The Mobile Station (MS) invokes the service by sending a FACILITY message to the network containing the ECT request (ECT request). This ECT request indicates to the network that the mobile subscriber wishes the two calls to be connected together. The MS shall not change the basic call state or the auxiliary state of either call when sending ECT request. The network will normally accept the ECT request and connect the two calls, indicates the success of the ECT request to the served subscriber and disconnect afterwards the served mobile subscriber from both calls (see figure 1). If the ECT request is not accepted, the network will indicate the error to the served subscriber (see figure 1) and leaves the two calls to the condition it was in prior to the ECT request. The network confirms with the same transaction identifier. The detailed coding of the different error values are specified in GSM 04.80. Which error value is used in which error case is described below. During the ECT operation the MS shall run a timer TECT. This timer is started when the operation is sent, and stopped when a response is received from the network. If this timer expires the MS shall assume that the operation has failed, locally release the invokeID, and may re-attempt the operation or inform the user of the failure. 4.2 Explicit Call Transfer invocation MS Network FACILITY (TI A-B/A-C) ---------------------------------------------------------------------------------------------------------------------> Facility (Invoke = ExplicitCT) DISCONNECT/RELEASE/RELEASE COMPLETE (TI A-B/A-C) <--------------------------------------------------------------------------------------------------------------------- Facility (Return result) DISCONNECT/RELEASE/RELEASE COMPLETE (TI A-C/A-B) <--------------------------------------------------------------------------------------------------------------------- FACILITY (TI A-B/A-C) <- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -- - - - - - - - - -- - - - - - - Facility (Return error (Error)) FACILITY (TI A-B/A-C) <- - - - -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -- - - - - - - - - -- - - - - - - Facility (Reject (Invoke_problem)) NOTE: A-B/A-C indicates a choice. The Transaction Identifier (TI) used for the invocation of ECT shall be that of the active/answered call or of the held call. A-C/A-B indicates the TI of the other call. Figure 1: Invocation of Explicit Call Transfer (3G TS 24.091 version 3.0.0 Release 1999) ETSI TS 124 091 V3.0.0 (2000-01) ETSI 3GPP 3G TS 24.091 V3.0.0 (1999-05) 8 3G TS 24.091 version 3.0.0 In the following table, the use of the different error values is described: Table 1: Error values Error Error case IllegalSS-Operation - operation violates the general rules applicable to the service - different calls and either off them or two are not TS 11 (telephony) - one or both of the calls are in the wrong call states - having only one call or one call is clearing - creation of a traffic channel loop SS-ErrorStatus - the served subscriber has not subscribed to ECT SS-NotAvailable - SS is not available in current location area SS-Incompatibility - SS-Interaction violation FacilityNotSupported - Facility not supported in VPLMN SystemFailure - problems in an entity or network resources ResourcesNotAvailable - problems to allocate resources CallBarred - contravention with the active barring program 4.3 Notification to the remote parties If the network received a non-zero SS Screening indicator from the remote party's MS the network shall send a notification to the remote party indicating that the call has been transferred and towards the previously-held party to indicate that he is now retrieved. If the network did not receive a non-zero SS Screening indicator from the remote party's MS it shall not send a notification. The content of the Notification Indicator and the Redirection Number in detail is given in GSM 03.91 and the coding in GSM 04.80. For the following it is assumed that the Line Identities of the remote parties are available and allowed to be presented to the remote parties. 4.3.1 Notification to the held remote party If ECT was invoked in the active state the previous-held remote party will be notified at the invocation of ECT (see figure 2).

It is however, an operator option to support the invocation of ECT by these mobile stations. Where operators support this option, the mechanism employed to offer the ECT service to these MSs shall be USSD. However, it should be noted that it may not be possible using this mechanism to offer the same degree of service to the served subscriber as described in clause 4. 5.1 Explicit Call Transfer invocation MS A invokes the service by sending a REGISTER message to the network using a call independent supplementary service (SS) transaction, with the facility information element, indicating ProcessUnstructuredSS-Request (the MMI is specified in GSM 02.30). If the invocation of ECT is successful, then after the SS transaction has been cleared, the network shall release the CC transactions. If the invocation of ECT is not successful, then the CC transactions shall not be released.

The MS shall respond to the request by sending a FACILITY message containing the user's mobile subscriber's response in a return result component. The network shall pass the data received in the response to the application handling USSD operations and shall wait for the response of the application. The application may either continue or terminate the dialogue. When the application continues the dialogue, it may initiate another USSD operation by sending a FACILITY message (see figure 5.2). The operation may either be an USSD request or notification (see subclause 5.1.2). When the application terminates the dialogue, the network shall clear the transaction by sending a RELEASE COMPLETE message. The MS may also clear the transaction at any time by sending a RELEASE COMPLETE message upon the request of the user. If the MS is unable to process the request received from the network, it shall return an error indication by sending a FACILITY message containing a return error component. Error values are specified in GSM 04.80. When the MS receives an USSD operation in parallel to any call independent supplementary service transaction, it shall respond with a return error component in a RELEASE COMPLETE message, containing the "USSD-Busy" error as specified in GSM 04.80, to indicate the failure in handling a parallel USSD operation. However, the network is allowed to initiate USSD operations in parallel to call related transactions.

The MS shall acknowledge the operation by sending a FACILITY message containing an empty result component to the network. The application may either continue or terminate the dialogue. When the application continues the dialogue, it may initiate another USSD operation by sending a FACILITY message (see figure 5.4). The operation may either be an USSD request (see subclause 5.1.1) or notification. When the application terminates the dialogue, the network shall clear the transaction by sending a RELEASE COMPLETE message. The MS may also clear the transaction at any time by sending a RELEASE COMPLETE message upon request of the user. If the MS is unable to process the request received from the network, it shall return an error indication by sending a FACILITY message containing a return error component. Error values are specified in GSM 04.80. When the MS receives an USSD operation in parallel to any call independent supplementary service transaction, it shall respond with a return error component in a RELEASE COMPLETE message, containing the "USSD-Busy" error as specified in GSM 04.80, to indicate the failure in handling a parallel USSD operation. However, the network is allowed to initiated USSD operations in parallel to call related transactions.

c0dd1f49bffdd1daa285ed67ebae4b56 | 124 088 | 0 Scope | This Technical Specification (TS) specifies the procedures used at the radio interface (reference point Um as defined in GSM 04.02) for normal operation, registration, erasure, activation, deactivation, invocation and interrogation of call barring supplementary services. Provision and withdrawal of supplementary services is an administrative matter between the mobile subscriber and the service provider and cause no signalling on the radio interface. In GSM 04.10 the general aspects of the specification of supplementary services at the layer 3 radio interface are given. GSM 04.80 specifies the formats and coding for the supplementary services. Definitions and descriptions of supplementary services are given in GSM 02.04, GSM 02.8x and GSM 02.9x-series. Technical realization of supplementary services is described in GSM 03.11, GSM 03.8x and GSM 03.9x-series. The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3 radio interface are defined in GSM 04.07 and GSM 04.08. The following supplementary services belong to the call restriction supplementary services and are described in this specification: - Barring of outgoing calls (clause 1): - Barring of all outgoing calls (BAOC) (Barring program 1); - Barring of outgoing international calls (BOIC) (Barring program 2); - Barring of outgoing international calls EXCEPT those directed to the home PLMN country (BOIC-exHC) (Barring program 3). - Barring of incoming calls (clause 2): - Barring of all incoming calls (BAIC) (Barring program 1); - Barring of incoming calls when roaming outside the home PLMN country (BIC-Roam) (Barring program 2). 0.1 Normative references References may be made to: a) specific versions of publications (identified by date of publication, edition number, version number, etc.), in which case, subsequent revisions to the referenced document do not apply; or b) all versions up to and including the identified version (identified by "up to and including" before the version identity); or c) all versions subsequent to and including the identified version (identified by "onwards" following the version identity); or d) publications without mention of a specific version, in which case the latest version applies. A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the same number.

The main body of this specification assumes that all network entities comply with this version of the service. In each case an additional subclauses 1.7 and 2.7 defines the additional requirements for when one or more network entities or the MS complies with the protocol version 1 specifications for the supplementary service procedures. ETSI TS 124 088 V3.0.0 (2000-01) (3G TS 24.088 version 3.0.0 Release 1999) ETSI 3GPP 3G TS 24.088 V3.0.0 (1999-05) 8 3G TS 24.088 version 3.0.0 1 Barring of outgoing calls 1.1 Normal operation When a barring program relating to outgoing calls is active and operative for a basic service, each call set up related to that basic service and not allowed by the barring program will be refused by the network. In this case a NotifySS operation containing the SS-Status indicating that a barring program relating to outgoing calls is currently active and operative will be sent to the served mobile subscriber in a clearing message (see figure 1.1). MS Network SETUP ------------------------------------------------------------------------------------------------------------------------> DISCONNECT/RELEASE/RELEASE COMPLETE <------------------------------------------------------------------------------------------------------------------------ Facility (Invoke = NotifySS (SS-Code, SS-Status)) NOTE 1: The SS-Code will be the common code for outgoing barring services. NOTE 2: $(CAMEL2)$ The DISCONNECT and RELEASE messages were introduced because of CAMEL Phase 2. Figure 1.1: Notification to the served mobile subscriber that barring of outgoing calls is active When a barring program is active (operative or quiescent), the ability of the served mobile subscriber to set up emergency calls is not affected, irrespective of the basic service to which the barring program applies. When a barring program relating to outgoing calls is active (operative or quiescent), the ability of the served mobile subscriber to receive calls is not affected. 1.2 Registration If the served mobile subscriber at provision time has selected the subscription option "control of barring service: by subscriber using password", the subscriber has to register a call barring password at provision time. Furthermore the served mobile subscriber can change the call barring password by a registration procedure at any time. If the served mobile subscriber at provision time has selected the subscription option "control of barring service: by service provider", an attempt to register a new call barring password will be denied. The procedure to register a new password is specified in GSM 04.10. ETSI TS 124 088 V3.0.0 (2000-01) (3G TS 24.088 version 3.0.0 Release 1999) ETSI 3GPP 3G TS 24.088 V3.0.0 (1999-05) 9 3G TS 24.088 version 3.0.0 1.3 Activation If the served mobile subscriber at provision time has selected the subscription option "control of barring service: by subscriber using password", the supplementary service is activated for a basic service if the subscriber has requested so by means of an activation procedure for that basic service. If the subscriber does not indicate a specific basic service, the activation applies to all basic services. The subscriber may use the call barring password at activation (see figure 1.2). If the activation is successful, the service will be activated. The network will then send a return result indicating acceptance of the request. The result is formatted according to the options shown below: - The result includes the Basic Service group Code(s) to which the service is activated. The result may also contain an SS-Code and SS-Status parameter. If the MS does not send an SS Version Indicator in the invocation request then these parameters shall be presented in the result. If the MS does send an SS Version Indicator in the invocation request then these parameters are optional in the result. If the SS-Status is included the network shall set it to reflect the state of the service. If the SS-Code is included then it shall contain the SS-Code of the service which has been activated. The MS shall ignore the contents of the SS-Code and SS-Status parameters if they are received. Note that the use of SS-Code and SS-Status is to provide backwards compatibility with GSM Phase 1. - If the request did not include a BasicServiceCode, and the activation was successful for all basic services, the network may send an empty return result to the MS. This option applies whether or not an SS Version Indicator is received from the MS. If the served mobile subscriber at provision time has selected the subscription option "control of barring service: by service provider", an attempt to activate the service will be denied and the served mobile subscriber receives an error indication (see figure 1.3). Error values are specified in GSM 04.80.

The subscriber may use the call barring password at deactivation (see figure 1.3). The deactivation request of a barring program may specify the basic service. If the subscriber does not indicate a specific basic service, the deactivation applies to all basic services (see figure 1.3). If the deactivation is successful, the service will be deactivated. The network will then send a return result indicating acceptance of the request. The result is formatted according to the options shown below: - The result includes the Basic Service group Code(s) to which the service is deactivated. The result may also contain an SS-Code and SS-Status parameter. If the MS does not send an SS Version Indicator in the invocation request then these parameters shall be presented in the result. If the MS does send an SS Version Indicator in the invocation request then these parameters are optional in the result. If the SS-Status is included the network shall set it to reflect the state of the service. If the SS-Code is included then it shall contain the SS-Code of the service which has been deactivated. The MS shall ignore the contents of the SS-Code and SS-Status parameters if they are received. Note that the use of SS-Code and SS-Status is to provide backwards compatibility with GSM Phase 1. - If the request did not include a BasicServiceCode, and the deactivation was successful for all basic services, the network may send an empty return result to the MS. This option applies whether or not an SS Version Indicator is received from the MS. If the served mobile subscriber at provision time has selected the subscription option "control of barring service: by service provider", an attempt to deactivate the supplementary service will be denied and the served mobile subscriber receives an error indication (see figure 1.3).

Figure 2.1: Notification to the calling mobile subscriber that at the called subscriber side barring is active When barring of incoming calls is active (operative or quiescent), the ability of the served mobile subscriber to originate calls is not affected. 2.2 Registration If the served mobile subscriber at provision time has selected the subscription option "control of barring service: by subscriber using password", the subscriber has to register a call barring password at provision time. Furthermore the served mobile subscriber can change the call barring password by a registration procedure at any time. If the served mobile subscriber at provision time has selected the subscription option "control of barring service: by service provider", an attempt to register a new call barring password will be denied. The procedure to register a new password is specified in GSM 04.10.

If the subscriber does not indicate a specific basic service, the activation applies to all basic services. The subscriber may use the call barring password at activation (see figure 2.2). If the activation is successful, the service will be activated. The network will then send a return result indicating acceptance of the request. The result is formatted according to the options shown below: - The result includes the Basic Service group Code(s) to which the service is activated. The result may also contain an SS-Code and SS-Status parameter. If the MS does not send an SS Version Indicator in the invocation request then these parameters shall be presented in the result. If the MS does send an SS Version Indicator in the invocation request then these parameters are optional in the result. If the SS-Status is included the network shall set it to reflect the state of the service. If the SS-Code is included then it shall contain the SS-Code of the service which has been activated. The MS shall ignore the contents of the SS-Code and SS-Status parameters if they are received. Note that the use of SS-Code and SS-Status is to provide backwards compatibility with GSM Phase 1. - If the request did not include a BasicServiceCode, and the activation was successful for all basic services, the network may send an empty return result to the MS. This option applies whether or not an SS Version Indicator is received from the MS. If the served mobile subscriber at provision time has selected the subscription option "control of barring service: by service provider", an attempt to activate the service will be denied and the served mobile subscriber receives an error indication (see figure 2.2).

The subscriber may use the call barring password at deactivation (see figure 2.3). If the deactivation is successful, the service will be deactivated. The network will then send a return result indicating acceptance of the request. The result is formatted according to the options shown below: - The result includes the Basic Service group Code(s) to which the service is deactivated. The result may also contain an SS-Code and SS-Status parameter. If the MS does not send an SS Version Indicator in the invocation request then these parameters shall be presented in the result.

For service 3 the remote party can be either the called or the calling party of an established call to whom the use of the UUS supplementary service is requested by the served subscriber. Served subscriber: The subscriber who has a provision of the UUS supplementary service and who activates the UUS supplementary service. For service 1 and 2 the served subscriber is always the calling subscriber, for service 3 either the calling or the called subscriber can be the served subscriber. User-to-User Information (UUI): The information transferred by using the UUS supplementary service. UUS not required: If the "UUS not required" indication is given by the subscriber, the call will be completed even if UUI cannot be passed to the called subscriber. ETSI TS 124 087 V3.0.0 (2000-01) (3G TS 24.087 version 3.0.0 Release 1999) ETSI 3GPP 3G TS 24.087 V3.0.0 (1999-05) 6 3G TS 24.087 version 3.0.0 UUS required: If the "UUS required" indication is given by the subscriber, the call shall not be completed if UUI cannot be passed to the called subscriber. UUS Service: The UUS services (Service 1, 2 and 3) are components of the UUS supplementary service. If the UUS supplementary service is provided to a subscriber, he can handle the UUS services independently within a call. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: MS A Mobile Station A, the mobile station of the served subscriber MS B Mobile Station B, the mobile station of the remote subscriber UUI User-to-User Information UUS User-to-User Signalling UUS1 User-to-User Signalling Service 1 UUS2 User-to-User Signalling Service 2 UUS3 User-to-User Signalling Service 3 Further GSM related abbreviations are listed in GSM 01.04. 4 User-to-User Signalling (UUS); served mobile subscriber side 4.1 UUS1 For UUS1, both parties may exchange UUI during the set-up and the clearing phases of a call by including User-user information element(s) in basic call control messages (ALERTING, CONNECT, DISCONNECT, PROGRESS, RELEASE, RELEASE COMPLETE, SETUP). UUS1 can be activated implicitly or explicitly. When UUS1 has been activated, either subscriber may include UUI when accepting, rejecting or terminating the call. UUS1 is automatically deactivated when the call is cleared. ETSI TS 124 087 V3.0.0 (2000-01) (3G TS 24.087 version 3.0.0 Release 1999) ETSI 3GPP 3G TS 24.087 V3.0.0 (1999-05) 7 3G TS 24.087 version 3.0.0 4.1.1 Operation when implicitly activated To activate UUS1 implicitly, the MS A shall include a User-user information element in the SETUP message as part of a normal call request. See GSM 04.08. Implicitly activated UUS1 is active for the duration of the call; i.e. the remote party is not required to send a response to the implicit activation request. However, the remote party may include a User-user information element in the call response. The served subscriber or the remote party may terminate the call before a connection is established. MS A NETWORK SETUP -----------------------------------------------------------------------------------------------------------------------------> User-user . ALERTING <---------------------------------------------------------------------------------------------------------------------------- User-user (Note 1) CONNECT <---------------------------------------------------------------------------------------------------------------------------- User-user (Note 1) . . DISCONNECT / RELEASE / RELEASE COMPLETE <---------------------------------------------------------------------------------------------------------------------------> User-user (Note 1), (Note 2) NOTE 1: The User-user information element is optional. NOTE 2: Under normal conditions DISCONNECT message is used for clearing the call, but also RELEASE or RELEASE COMPLETE message may be used as the first call clearing message. Figure 1: UUS1 when implicitly activated 4.1.2 Operation when explicitly activated UUS1 is explicitly requested by the MS A when including a Facility information element with a UserUserService invoke component in the SETUP message. See GSM 04.08, GSM 04.80. The UserUserService invoke component shall indicate whether the service is "UUS required" or "UUS not required". If the remote party accepts the request, the network shall include a Facility information element with a UserUserService Return Result component in the ALERTING or the CONNECT message sent to the MS A. If the request is not accepted, the network shall include a Facility information element with a UserUserService Return Error component in the DISCONNECT message (when UUS required) or in the ALERTING or in the CONNECT message (when UUS not required) sent to the MS A. See errors in GSM 04.80. An explicit activation request may include UUI. The network may include User-user information element when accepting the activation request. The served subscriber or the remote party may terminate the call before a connection is established. For UUS1 explicit activation SS Version Indicator value 3 or above has to be used.

848488317adf16c49e39417600a4774c | 124 086 | 0 Scope | The present document specifies the procedures used at the radio interface (reference point Um as defined in GSM 04.02) for normal operation, registration, erasure, activation, deactivation, invocation and interrogation of charging supplementary services. The provision and withdrawal of supplementary services is an administrative matter between the mobile subscriber and the service provider and causes no signalling on the radio interface. In GSM 04.10 the general aspects of the specification of supplementary services at the layer 3 radio interface are given. GSM 04.80 specifies the formats and coding for the supplementary services. Definitions and descriptions of supplementary services are given in GSM 02.04 and GSM 02.8x and GSM 02.9x-series. GSM 02.24 and 02.86 are related to the charging supplementary services. Technical realization of supplementary services is described in GSM 03.11 and GSM 03.8x and GSM 03.9x-series. GSM 03.86 is related to the charging supplementary services. The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3 radio interface are defined in GSM 04.07 and GSM 04.08. The following supplementary services belong to the charging supplementary services and are described in the present document: - Advice of Charge (Information) (AoCI) (clause 1); - Advice of Charge (Charging) (AoCC) (clause 2). 0.1 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. • A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the same number.

The network sends the Charge Advice Information (CAI) to the MS according to GSM 02.24, GSM 02.86 and GSM 03.86. With this information the MS is able to calculate the units associated with the requested service in real time. In the case where the served mobile is to be charged for multi party calls, separate processes within the MS are used to calculate units appropriate to each call. For unit calculation, each call is treated in the same way as a normal "two-party" call. Any change in the charging rate during a call may be indicated to the MS. 1.1.1 Call re-establishment When the MS detects a radio link failure, the Chargeable Duration (CDUR) shall be suspended. If a call re-establishment procedure is attempted, the MS shall resume the CDUR when: - an MM connection has been successfully completed; and - a TCH has been successfully seized in the appropriate mode. 1.1.2 MS originated call For an MS originated call, charging information is transferred to the MS as shown in figure 1.1. The charging information is acknowledged in a FACILITY message only if the MS supports the AoCI functionality specified in GSM 02.24 and GSM 02.86. AoCI refers to the Advice of Charge (Information) service.
