The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of this TS, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the specification; ETSI ETSI TS 122 066 V3.2.0 (2000-06) 5 3G TS 22.066 version 3.2.0 Release 1999 1 Scope This TS defines the stage one description of the Support of Mobile Number Portability between networks in the same country as well as North America cross-sector portability (i.e.,. number portability between fixed and GSM mobile networks). Stage one is an overall service description, primarily from the service subscriber's and user's points of view, but does not deal with the details of the human interface itself. Mobile Number Portability (MNP) is applicable only to those telecommunication services identified by an MSISDN. This specification includes information applicable to network operators, service providers and terminal, switch and database manufacturers. This specification contains the core requirements for the Support of Mobile Number Portability between network operators in the same country as well as North America cross-sector portability which are sufficient to provide a complete service. Other cross-sector portability options (e.g. number portability between fixed and mobile networks outside the North American Region) are outside the scope of this technical specification. It is highly desirable however, that technical solutions for MNP should be sufficiently flexible to allow for possible enhancements, e.g. cross-sector number portability, and MNP between analogue and digital mobile networks. Additional functionalities not documented in this specification may implement requirements which are considered outside the scope of this specification. This additional functionality may be on a network-wide basis, nation-wide basis or particular to a group of users. Such additional functionality shall not compromise conformance to the core requirements of the service. Porting between Service Providers (i.e. service provider portability) which does not involve a change of Network Operator is outside the scope of this specification. The relationship between Service Providers and Network Operators is outside the scope of this specification. The relationship between a Service Provider and subscriber is outside the scope of this specification. The interface between the Mobile Station (MS) and any external applications are outside the scope of this specification. Charging principles are outside the scope of this specification except where explicitly stated in the text. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies. • For this Release 1999 document, references to GSM documents are for Release 1999 versions (version 8.x.y).

A DN can be a 10-digit number in the context of the North American Numbering Plan (without a country code) or up to 15 digits for an international number(country code included). donor network: The subscription network from which a number is ported in the porting process. This may or may not be the number range owner network. mobile number portability: The ability for a mobile subscriber to change digital mobile subscription network within the same country retaining their original DN(s). Additional regulatory constraints apply in North America. network operator: A PLMN operator. North American GSM number portability: the ability for a subscriber to change subscription between North American GSM networks and other subscription networks within an FCC regulated geographical area within North America originating network: the network where the calling party is located. ported number: Is a MSISDN that has undergone the porting process. ported subscriber: The subscriber of a ported number. porting process: A description of the transfer of a number between network operators. recipient network: The network which receives the number in the porting process. This network becomes the subscription network when the porting process is complete. service provider: An entity which offers service subscriptions to individual subscribers and contracts with a network operator to implement services for a specific DN. A service provider may contract with more than one network operator. service provider portability: The transfer of numbers between two unique Service Providers. subscription network: The network with which the customer’s Service Provider has a contract to implement the customer’s services for a specific DN. NOTE: The term "recipient network" is used during the porting process. The recipient network becomes the "subscription network" after the completion of the porting process. 3.2 Abbreviations For the purposes of this specification the following abbreviations apply: DN Directory Number MMI Man Machine Interface MNP Mobile Number Portability MSISDN Mobile Station ISDN number NAGNP North American GSM Number Portability PLMN Public Land Mobile Network SIM Subscriber Identity Module USIM Universal Subscriber Identity Module ETSI ETSI TS 122 066 V3.2.0 (2000-06) 7 3G TS 22.066 version 3.2.0 Release 1999 Further related abbreviations are given in GSM 01.04 [1] and TR 21.905 [2]. ETSI ETSI TS 122 066 V3.2.0 (2000-06) 8 3G TS 22.066 version 3.2.0 Release 1999 4 Applicability Mobile Number Portability cannot be offered to a subscriber as a stand alone service. Mobile Number Portability is applicable to all teleservices (e.g. SMS, voice, fax) and bearer services (e.g. data), except for TS12 (emergency call). The implementation of MNP shall be flexible enough to apply to each DN of a subscriber separately. Where the DNs used in the donor network are ported to different recipient mobile networks then a new IMSI (and SIM/USIM) will be required for each recipient network. The basic and supplementary services provisioned in the recipient network shall not be dependent on those that were provisioned in the donor network. 5 Description Mobile Number Portability (MNP) is the ability for a mobile subscriber to change digital mobile subscription networks within the same country whilst retaining her original DN or DNs. Additional regulatory constraints apply in North America. North American GSM Number Portability (NAGNP) is the ability for a subscriber to change subscription between North American GSM networks and other subscription networks within an FCC regulated geographical area within North-America. The IMSI shall not be ported, hence the recipient mobile network of the porting process will issue a new IMSI for the ported subscription. The porting process may, but need not, include a change in service provider. The ported subscriber can use exactly the same services as non-ported customers in the same subscription network. That is: whether the DN of a subscriber belongs to a subscription network or is ported to the subscription network shall have no influence on the services offered to the customer by that subscription network. The services offered by the number range owner network and/or the donor network have no influence on the services offered by the subscription network. When a subscriber ports a DN to a new network then the donor network no longer provides support for the services of the ported number (this includes supplementary and value added services). NOTE: This also implies that if a service supported in the donor network is not available on the recipient network then number portability mechanisms need not provide that service for the ported subscriber. A network can be a donor of numbers and a recipient of numbers. A DN can be ported more than once; a ported number can be ported back to its number range owner network. Even after multiple portings, the technical solution shall involve only the number range owner network and recipient network. The solution for MNP/NAGNP shall have a minimal adverse effect upon the quality of service offered to ported and non-ported subscribers. It may be the case that the quality of service for ported and non-ported subscribers differs slightly (e.g. due to additional call set-up delay). Any additional delay in call set-up to ported numbers shall be minimised. The process of porting a number may involve a disruption in service to the customer. The time that no service is available shall be minimised. The technical implementation of the support of MNP/NAGNPin a network should not impede number availability and efficient use of numbers. The technical implementation for the support of MNP/NAGNPshall not involve loss of functionality in the number range owner, donor or subscription network. The technical implementation of MNP/NAGNPshall support optimisation of the use of network and inter-network resources so as to minimise costs associated with transport of traffic and/or appropriate signalling and/or processing activities (e.g. optimal routing). In addition, for the porting process an efficient and effective way is needed to exchange porting information between all types of network operators. ETSI ETSI TS 122 066 V3.2.0 (2000-06) 9 3G TS 22.066 version 3.2.0 Release 1999 6 Normal procedures with successful outcome Mobile Number Portability is offered to all subscribers of telephone services subject to regulatory requirements. A porting process is initiated at a subscriber’s request on their selected DN(s) with the relevant networks. Initiation of the porting process is an off-line administrative process and cannot be invoked via a specific MMI on the hand-set. After successful porting the subscriber, is able to use the provisioned telephone services and network specific services of the subscription network as offered to non-ported subscribers on that network. Porting will effectively initiate a new subscription As part of the porting process, the donor, number range owner and recipient networks shall update their relevant network elements in order to perform the porting. After the porting process is complete, the subscription details related to the ported DN on the donor network shall not be required and can be deleted. Therefore, only the number range owner network and the recipient network are involved in the MNP/NAGNPsolution for support of service to the ported subscriber. The originating network may not be aware of the ported nature of the number; therefore the technical solution shall work even if networks other than the number range owner and recipient have no knowledge of the ported nature of the number. NOTE: Other networks may be involved to increase the efficiency of call-set-up to ported numbers. When a ported subscriber takes an additional DN at her subscription network that additional DN should not have to come from the number range owner network(s) of the subscriber’s ported numbers. Where number ranges are assigned to network operators, the number range owner network shall receive the ported number back from the recipient network when the subscriber relinquishes the ported number, i.e. when the ported number ceases to be an active service number. 7 Exceptional procedures Service related data (e.g. numbers used in the call-forwarding service, etc.) may not be transferred to the recipient network during the porting process. 8 Addressing As a consequence of MNP, the DN of a subscriber may no longer explicitly identify the subscription network of that subscriber. 9 Supplementary Services and Service Interworking The support of mobile Number Portability in a network shall not affect the handling of supplementary service for the subscribers, i.e. there shall be no difference in the handling of the supplementary services between ported in and normal subscribers of the same network. 9.1 Calling line identification presentation (CLIP) No impact. 9.2 Calling line identification restriction (CLIR) No impact.

NOTE: This is a service requirement. However, it may be difficult to find an MNP solution with no impact on Optimal Routing. 11 Networking interworking All services offered in co-operation with other types of networks shall still be offered in combination with MNP. This includes the basic services, all supplementary services and all network features. 12 Charging aspects No additional charging mechanisms relating to the calling party are to be standardised. Enough information should be collected to allow the involved networks to workout inter-network charging. 13 Lawful Interception Issues Lawful interception shall be possible on a ported MSISDN.

According to GSM 02.72 this may happen as an automatic response from the mobile station if the call is offered or as the result of a subscriber action. The mobile station shall invoke the call deflection supplementary service by initiating call clearing with a DISCONNECT message including the call deflection request (refer to figure 4.1). The call deflection request shall contain the DeflectedToNumber which may be accompanied by a DeflectedToSubAddress. The MS may invoke the call deflection supplementary service at every time after call confirmation until the call is accepted (refer to GSM 04.08). If the network accepts the call deflection request, it shall continue call clearing. The result indication shall be returned to the mobile station in the RELEASE message. If the network cannot accept the call deflection request, it shall continue call clearing. The corresponding error indication shall be returned to the mobile station in the RELEASE message. Error values are specified in GSM 04.80. During the call deflection request the MS shall run a timer TCD. This timer is started when the call deflection request is sent and stopped when a response is received from the network. If this timer expires the MS shall assume that the call deflection request has failed, locally release the invokeID, inform the user of the failure and continue call clearing as defined in GSM 04.08.

When available, the SS Code of the Call Deflection supplementary service is included, see figure 4.2. When multiple diversions occurs the value of the SS Code shall relate to the last invoked diversion service. In addition the deflected-to subscriber will receive the redirecting party BCD number and optionally, a redirecting party subaddress. The redirecting party BCD number information element is made up of a number of information units as defined in GSM 04.08. In addition to or instead of the redirecting party's digits, the subscriber may be given the following information: - screening indicator; - presentation indicator.

[4] TR 21.905: "Vocabulary for 3GPP Specifications". 3 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following definitions apply: Definition of name identity: The name identity is made up of the following information unit: - The name of the mobile subscriber for the purpose of calling name presentation - up to 80 characters of information associated with a specific calling party. The calling name identity is the name identity of the calling party. Definition of Presentation Indicator: In addition to or instead of the name identity, the network may give a Presentation Indicator (PI) to the called mobile subscriber of the CNAP service. The following information may be given: - Presentation Indicator (PI) showing: a) presentation restricted, or ETSI TS 122.096 V3.0.1 (2000-01) 3G TS 22.096 version 3.0.1 (3G TS 22.096 version 3.0.1 Release 1999) ETSI ETSI 3GPP 3G TS 22.096 V3.0.1 (1999-10) 6 3G TS 22.096 version 3.0.1 b) name unavailable. The name identity of a PLMN subscriber shall always be provided by the network. Calling Party: The calling party is the originating party. Called Party: The called party is the terminating party. The CNAP service is provided to the called party. Calling Name Information: The calling name information of the calling party includes either the calling name identity or an indication of privacy or unavailability. 3.2 Abbreviations In addition to the following abbreviations used in the present document, abbreviations are listed in GSM 01.04. CNAP Calling Name Presentation 4 Calling Name Presentation (CNAP) 4.1 Definition The CNAP supplementary service enables the called party to receive the calling name information of the calling party. 4.2 Description 4.2.1 Description This supplementary service provides for the ability to indicate the name information of the calling party to the called party at call set-up time for all incoming calls. The calling party takes no action to activate, initiate, or in any manner provide Calling Name Identification Presentation. However, the delivery of the calling name to the called party may be affected by other services subscribed to by the calling party. For example, if the calling party has subscribed to Calling Line Identification Restriction (CLIR), then the calling line identity as well as the calling name identity shall not be presented to the called party. 4.2.2 Applicability to telecommunication services The applicability of this supplementary service is defined in TS 22.004 [2]. CNAP is applicable to all telecommunication services except Short Message service. (for further study) 4.3 Normal procedures with successful outcome 4.3.1 Provision This supplementary service is provisioned for all Basic Services subscribed to and to which it is applicable, i.e. not provisioned for any subset of these Basic Services. This service shall be provided after pre-arrangement with the service provider. It may be provided on a subscription basis or be generally available. ETSI TS 122.096 V3.0.1 (2000-01) 3G TS 22.096 version 3.0.1 (3G TS 22.096 version 3.0.1 Release 1999) ETSI ETSI 3GPP 3G TS 22.096 V3.0.1 (1999-10) 7 3G TS 22.096 version 3.0.1 The override category controlling the name information is separate from the override category for the line identity information. It is left to the CNAP service provider to ensure that no discrepancy between these two override categories occurs. The handling of override category within a PLMN or between PLMNs shall follow the rules applying to the override category of the line identification services TS 22.081 [3]. 4.3.2 Withdrawal The CNAP supplementary service shall be withdrawn at the customer's request or for administrative reasons. 4.3.3 Registration Not applicable. 4.3.4 Erasure Not applicable. 4.3.5 Activation The CNAP supplementary service is activated as a result of provision. 4.3.6 Deactivation The CNAP supplementary service is deactivated as a result of withdrawal. 4.3.7 Invocation The network shall automatically invoke the CNAP supplementary service in the call set-up phase to the terminating CNAP subscriber. CNAP is invoked when the Calling Name Information associated with an incoming call is available and can be presented to the called party which has subscribed to CNAP. 4.3.8 Normal operation with successful outcome A user who has subscribed to the CNAP supplementary service and receives a call shall also receive the calling name information of the calling party, if available. The calling party takes no action to activate, initiate, or in any manner provide the calling name identity. When the CNAP service is subscribed and activated, the destination network provides the called subscriber with calling name information at call set-up on all incoming calls or during an active call for that particular call. In addition to, or instead of, the calling name identity, the subscriber may be given a presentation indicator with the relevant information. 4.3.9 Interrogation Status check The mobile subscriber can, by the appropriate control procedure, request from the network the status of this supplementary service. Upon receiving an interrogation request, the network shall send the status of this supplementary service to the subscriber. The information sent to the subscriber shall indicate whether the service is provided to her. The information sent in response to the interrogation of this supplementary service shall not imply the status of any other supplementary service. ETSI TS 122.096 V3.0.1 (2000-01) 3G TS 22.096 version 3.0.1 (3G TS 22.096 version 3.0.1 Release 1999) ETSI ETSI 3GPP 3G TS 22.096 V3.0.1 (1999-10) 8 3G TS 22.096 version 3.0.1 4.4 Exceptional procedures or unsuccessful outcome If the name identity for a specific caller is not available, then the CNAP subscriber shall be sent an indication that the name is unavailable. If the network has been unable to determine the appropriate name information within a predefined time, then the CNAP subscriber shall be sent an indication that the name is unavailable. The predefined time is a network dependent value such that the called user may receive the name in a timely manner prior to answer. If the calling name information is not available due to a system problem, such as signalling inter-working, then a standard error treatment shall be provided, which may be a visual display to the subscriber indicating the name is unavailable. 4.5 Alternate procedures The decision of whether the user-defined name stored in the handset should take precedence over the calling name identity provided by the network is a handset implementation issue. 4.6 Interactions with other supplementary services Only those supplementary services for which CNAP has any interactions are detailed in this clause. For all other supplementary services not mentioned in this clause no interactions were identified. 4.6.1 Calling Line Identification Presentation (CLIP) No interaction. 4.6.2 Calling Line Identification Restriction (CLIR) The CLIR supplementary service shall take precedence over the CNAP supplementary service, unless the called user has an override category. In this latter case, it is assumed that the override category for name information has been set so that the name information is presented to the called user. The Calling Line Identification Restriction (CLIR) information shall be used to restrict the delivery of the calling name to the called subscriber. That is, if the calling party has activated CLIR then instead of the calling name, a privacy indication shall be provided to the called subscriber, which may be a visual display indicating “private” (or Restricted) name. This method of restricting calling name shall not restrict the use or implementation of other calling name restriction methods when the calling party is a fixed subscriber. These methods used by fixed subscribers are outside the scope of this specification. 4.6.3 Call Forwarding Unconditional (CFU) For an incoming call to a subscriber with both CNAP and Call Forwarding Unconditional activated, the calling party name information shall not be displayed at the forwarding subscribers terminal. When a call has been forwarded and the forwarded-to user has been provided with the CNAP supplementary service, the forwarded-to user shall receive the name of the original calling party, if the calling party has not subscribed to or invoked the CLIR supplementary service. 4.6.4 Call Forwarding on mobile subscriber Busy (CFB) 4.6.4.1 Network Determined User Busy (NDUB) Same as the interaction with call forwarding unconditional. ETSI TS 122.096 V3.0.1 (2000-01) 3G TS 22.096 version 3.0.1 (3G TS 22.096 version 3.0.1 Release 1999) ETSI ETSI 3GPP 3G TS 22.096 V3.0.1 (1999-10) 9 3G TS 22.096 version 3.0.1 4.6.4.2 User Determined User Busy (UDUB) Same as interaction with call forwarding no reply. 4.6.5 Call Forwarding on No Reply (CFNRy) For an incoming call to a subscriber with both CNAP and Call Forwarding on No Reply activated, the calling party name information shall be displayed by the predefined time while the call is alerting. 4.6.6 Call Forwarding on mobile subscriber Not Reachable (CFNRc) Same as the interaction with call forwarding unconditional. 4.6.7 Call Waiting (CW) If the served mobile subscriber is provisioned with the CNAP service, the calling party name information shall be displayed to the subscriber at the notification of an incoming (waiting) call as for a normal incoming call. 4.6.9 Explicit Call Transfer (ECT) For Further Study. 4.6.10 Support of Private Numbering Plan (SPNP) The public number corresponding to the used PNP number is used to obtain the calling name information for delivery to the called party’s terminal. 4.6.11 Completion of Calls to Busy Subscriber (CCBS) No interaction. 4.6.12 enhanced Multi-Level Precedence and Pre-emption (eMLPP) No interaction. 4.7 Service functions for roamers CNAP should be available to a roaming subscriber. However, the serving system may elect to not offer the CNAP service to any subscriber. According to national network specific rules, the CNAP supplementary services need not be applicable, if at least one of the two parties is not an ISDN or PLMN subscriber.

Initiating Subscriber A shall be able to manipulate the Follow Me data of remote party B such that subsequent calls directed to remote party B are forwarded to initiating subscriber A. Initiating subscriber A needs to have FM provisioned by her service provider. In case remote party B is a subscriber she needs to have FM provisioned by her service provider too. The FM service supervisor shall be able to modify the Follow Me data of the remote party who has been registered to another initiating subscriber. It remains in the responsibility of a FM provisioning service provider to confine a.) the range of remote parties for which a FM provisioned subscriber may become initiating subscriber b.) the range of potential initiating subscribers for a remote party. The mobile subscriber who has been provisioned Follow Me is able to use the following control operations: Registration available to the initiating subscriber Interrogation available to the initiating and remote party in case the remote party corresponds to a subscriber Erasure available to the initiating and remote party in case the remote party corresponds to a subscriber ETSI TS 122 094 V3.1.0 (2000-01) (3G TS 22.094 version 3.1.0 Release 1999) ETSI 3GPP 3G TS 22.094 V3.1.0 (1999-12) 7 3G TS 22.094 version 3.1.0 (There is no explicit activation or deactivation.) The FM service supervisor is able to use the following control operations: Interrogation Erasure (forced erasure) NOTE 1: The functionality of the Follow Me feature is equivalent to the Call Forwarding Unconditional Supplementary Service (see TS 22.082 [5]), controlled by initiating subscriber A and effecting remote party B. NOTE 2: The Follow Me feature is designed in such a way that the requirements of "functional addressing", which is needed for GSM-Railway operators, can be met. The concept of "functional addressing" enables a subscriber to set up a call to a "function" - e.g. the conductor - on a "train". The Follow Me feature identifies this "function" with the remote party B. Consequently a "functional number" is the equivalent to the number of remote party B (e.g. the MSISDN of a subscriber B). A call to that "functional number" (the conductor on a particular train - to stay with the example) will be forwarded to the MS of the person, who is on duty as a conductor at this time for this train. In the context of the Follow Me feature, this person (the train conductor) constitutes the "initiating subscriber" A, who has registered Follow Me with respect to the remote party B (the "function" train conductor). 4.1 Normal Operation Due to reduced security requirements to the Follow Me feature the service shall not be offered in standard operations of public GSM networks. In railway operations it must be enabled by definitive action on the part of the operator. Fraud Information Gathering System (FIGS) as specified in [11] can be used to protect in CAMEL based inter-working networks. The Follow Me feature shall be controlled by means of Subscriber Controlled Input using USSD. 5 Applicability to telecommunication services GSM 02.01 describes the principles of the Telecommunication services provided in a GSM PLMN. It also defines the concepts of Telecommunication services and describes their characterization by appropriate attributes. Bearer services and Teleservices, which are offered by a PLMN in connection with other networks, are defined in TS 22.002, GSM 02.03 and TS 22.101. A list of basic service groups can be found in GSM TS 22.004. Follow Me is applicable to the following telecommunication services: ETSI TS 122 094 V3.1.0 (2000-01) (3G TS 22.094 version 3.1.0 Release 1999) ETSI 3GPP 3G TS 22.094 V3.1.0 (1999-12) 8 3G TS 22.094 version 3.1.0 Table 1: Applicability of the Follow Me feature to telecommunication services Feature Telephony Emergency Call SMS PTP SMS-CB Fax cct Data PAD/Packet Access Voice Group Services TS11 TS12 TS21 TS22 TS 23 TS 6x BS2x, BS3x BS4x BS5x TS 91 TS 92 Follow Me Yes Yes Yes No1 No1 NOTE 1: The feature is in general not applicable for Voice Group Services. However a dispatcher may be an initiating subscriber or a remote party for the Follow Me feature. EDITOR's Note: The applicability of FM to SMS is for further study. 6 Normal procedures with successful outcome 6.1 Provision Follow Me shall be provided after prior arrangement with the service provider. Follow Me will be provisioned for all Basic Services subscribed to and to which it is applicable. NOTES: - A Follow Me provision is required for the initiating subscriber and for the remote party in case the remote party corresponds to a subscriber. - If Follow Me is provisioned for a mobile subscriber she may assume the role of an initiating subscriber and/or the role of a remote party. - A Follow Me provisioning service provider may confine: a.) the range of remote parties for which a FM provisioned subscriber may become initiating subscriber b.) the range of potential initiating subscribers for a remote party. c) the range of remote parties for which a FM provisioned subscriber may become FM service supervisor. NOTE: (Health warning on security) The Follow Me feature is designed in such a way as to meet the security requirements of GSM-Railway operators. If the Follow Me feature is to be used by other operators - in particular if the remote party corresponds to a subscriber - operators are strongly advised to care for additional suitable security mechanisms to protect the remote party from potential harm by misuse of FM. These mechanisms are out of scope of this specification. To support such mechanisms the possibility is foreseen to convey additional operator-specific information in the registration, interrogation and erasure procedures to the PLMN of the remote party. It should however be noted, that this is not a very secure mechanism. Operators should try to use existing security mechanisms where possible 6.2 Withdrawal Follow Me will be withdrawn at the subscriber's request or for administrative reasons. 6.3 Registration Follow Me shall be registered with an appropriate control procedure by the initiating subscriber. The initiating Subscriber registers the Follow Me feature with respect to a particular remote party. The initiating subscriber shall provide the following information to the network: the number of the remote party (e.g. the Basic MSISDN of a subscriber); ETSI TS 122 094 V3.1.0 (2000-01) (3G TS 22.094 version 3.1.0 Release 1999) ETSI 3GPP 3G TS 22.094 V3.1.0 (1999-12) 9 3G TS 22.094 version 3.1.0 The initiating subscriber shall receive an indication if the FM registration request was accepted or rejected by the network. As an operator's option additional information (such as passwords) for registration may be required from the initiating subscriber. The registration procedure shall transport this information from the initiating subscriber to the network of the remote party. This information shall be coded as a USSD string with a length not exceeding 30 characters. The content of this information and the use of it are out of scope of this specification. NOTE 1: The Follow Me feature may, at an instant, be registered to an initiating subscriber with respect to several remote parties. Conversely, a remote party can be registered only to one initiating subscriber at a time. 6.4 Erasure A previous FM registration can be erased in either of the following ways: a) The initiating subscriber can specifically erase her previous registration with an appropriate control procedure. b) In case the remote party corresponds to a subscriber the remote party can erase any previous registration with an appropriate control procedure. c) The FM service supervisor can erase any previous registration to any remote party with an appropriate control procedure (forced erasure). The subscriber who initiates the FM erase request shall be informed of the outcome of the request by the network. As an operator's option additional information (such as passwords) for erasure may be required from the subscriber. The registration procedure shall transport this information from the subscriber to the network of the remote party. This information shall be coded as a USSD string with a length not exceeding 30 characters. The content of this information and the use of it are out of scope of this specification. 6.5 Activation Follow Me is activated by registration. 6.6 Deactivation Follow Me is deactivated by erasure. 6.7 Invocation Follow Me is automatically invoked by the network if it was previously registered. If Follow Me is registered all incoming calls to the remote party will be forwarded to the initiating subscriber by network invocation. When Follow Me is active and operative and if the remote party is a subscriber, the ability of the remote party to originate calls is not affected. 6.8 Interrogation An initiating subscriber (also the FM service supervisor) shall be able to interrogate the Follow Me data of any remote party, for which she is authorised to become initiating subscriber. In case the remote party corresponds to a subscriber the remote party shall be able to interrogate her own Follow Me data stored in the network. The network shall return the basic MSISDN of the initiating subscriber for which the remote party is registered to Follow Me. ETSI TS 122 094 V3.1.0 (2000-01) (3G TS 22.094 version 3.1.0 Release 1999) ETSI 3GPP 3G TS 22.094 V3.1.0 (1999-12) 10 3G TS 22.094 version 3.1.0 As an operator's option additional information (such as passwords) for interrogation may be required from the subscriber. The registration procedure shall transport this information from the subscriber to the network of the remote party. This information shall be coded as a USSD string with a length not exceeding 30 characters. The content of this information and the use of it are out of scope of this specification. 7 Exceptional procedures or unsuccessful outcome 7.1 Registration If the system cannot accept a registration request, the initiating subscriber shall receive a notification that Follow Me registration was not successful. Possible causes are: - insufficient information; - feature not provisioned to initiating subscriber; - feature not provisioned to remote party (in case the remote party is a subscriber); - conflicting situation with supplementary services (e.g. incoming call barring has been activated); – remote party already registered to a different initiating subscriber – insufficient authorisation for initiating subscriber or remote party 7.2 Erasure If the network cannot accept a mobile initiating or remote subscriber's request for erasure, cause will be returned to the subscriber, such as: - insufficient information; - remote party not registered – remote party registered to a different initiating subscriber – insufficient authorisation for initiating subscriber or remote party - feature not provisioned to initiating subscriber; - feature not provisioned to remote party (in case the remote party is a subscriber); 7.3 Interrogation If the network cannot accept a mobile initiating or remote subscriber's request for interrogation, cause will be returned to the subscriber, such as: - insufficient information; – insufficient authorisation for initiating subscriber or remote party – feature not provisioned to initiating subscriber; - feature not provisioned to remote party (in case the remote party is a subscriber); ETSI TS 122 094 V3.1.0 (2000-01) (3G TS 22.094 version 3.1.0 Release 1999) ETSI 3GPP 3G TS 22.094 V3.1.0 (1999-12) 11 3G TS 22.094 version 3.1.0 7.4 Invocation Within a PLMN or different PLMNs the number of tandem forwarding connections (including call forwarding, call deflection, Follow Me) should be limited. The maximum number of tandem forwarding connections should be limited to a value between 1 and 5. This is to prevent infinite looping. If the limit of successive forwardings of a call has already been reached, an unsuccessful call set up indication is sent backwards. If the call cannot be completed to the Follow Me destination, then the network will clear the forwarded part of the call and an unsuccessful call set up indication is sent backwards. 8 Alternate procedures None identified. 9 Charging requirements None identified. 10 Interactions with supplementary services Interactions of the Follow Me feature with supplementary services may occur only for the remote party. The interactions of the Follow Me feature with supplementary services other than Call Forwarding Unconditional (CFU) are the same as the interactions of CFU with supplementary services (see TS 22.082 [5]). NOTE: The “served mobile subscriber” in TS 22.082 [5] corresponds to the “remote party” in this document. The “forwarded-to subscriber” in TS 22.082 [5] corresponds to the “initiating subscriber” in this document 10.1 Call Forwarding unconditional Follow Me and the Call Forwarding Unconditional Supplementary Service are mutually exclusive. That is: If Follow Me is registered with respect to a remote party, registration or activation of Call forwarding unconditional by the remote party is rejected. The remote party shall be informed of this incompatibility. If Call forwarding unconditional is registered or active for the remote party, registration of Follow Me is rejected. The initiating subscriber shall be informed of this incompatibility. 11 Interaction with Operator Determined barring Same as interaction between Operator Determined barring and call forwarding unconditional as defined in TS 22.041. 12 Interaction with Optimal Routeing Same as interaction between Optimal Routeing and call forwarding unconditional as defined in TS 22.079. 13 Interaction with CAMEL Same as interaction between CAMEL and call forwarding unconditional as defined in TS 22.078.

When interworking with non-PLMN or non-ISDN networks, tones and announcements will be required. NOTE1: The number of times a call has been forwarded once it has exited the PLMN or ISDN may not be limited. NOTE2: Tones and/or announcements should not be provided to the calling party if the information transfer capability is set to UDI.
