This document defines the Stage 2 architecture and specification for the CS Fallback and for SMS over SGs for EPS or CS Fallback and SMS over S102. The scope of this document includes the architecture enhancements for functionality to enable fallback from E-UTRAN access to UTRAN/GERAN CS domain access and to CDMA 1x RTT CS domain access, and functionality to reuse of voice and other CS-domain services (e.g. CS UDI video / LCS / USSD) by reuse of the CS domain. The functionality specified to support SMS over SGs does not trigger any CS Fallback to UTRAN/GERAN. The functionality specified to support SMS over S102 does not trigger any CS Fallback to CDMA 1xRTT CS domain. In addition this specification includes an SMS in MME architecture option for SMS services only. This functionality does not trigger any CS Fallback and does not require SGs. The architecture enhancements to support CS fallback to CDMA 1x RTT CS domain access for UEs with single and dual receiver configurations are specified in Annex B. In this Release of the specification no mechanisms are specified to support CS Fallback to both UTRAN/GERAN and CDMA 1xRTT in the same PLMN. So, even when a UE has the capability to support both CS Fallback to UTRAN/GERAN CS domain and CS Fallback to CDMA 1xRTT CS domain in a given PLMN, the PLMN implements only one of the two.

Enhancements for Multimedia Priority Service (MPS)
TR
1.4.0
S2
https://www.3gpp.org/ftp/Specs/archive/23_series/23.854/23854-140.zip
MPS will enable National Security/Emergency Preparedness (NS/EP) users (herein called Service Users) to make priority calls/sessions using the public networks. This service needs to be ensured also under special conditions such as network congestion. Service Users are the government-authorized personnel, emergency management officials and/or other authorized users. Effective disaster response and management rely on the Service User's ability to communicate during congestion conditions. Service Users are expected to receive priority treatment, in support of mission critical multimedia communications. The enhancements for MPS evaluated in this document are priority aspects of EPS packet bearer services and priority related interworking between IMS and EPS packet bearer services. These enhancements enable the network to support end-to-end priority treatment for MPS call/session origination/termination, including the Non Access Stratum (NAS) and Access Stratum (AS) signalling establishment procedures at originating/terminating network side as well as resource allocation in the core and radio networks for bearers. Priority treatment will be applicable to IMS based multimedia services, priority EPS bearer services and CS Fallback. This document clarifies the architectural requirements for MPS, considers the priority service scenarios, and evaluates solution alternatives. Solutions will be proposed and evaluated based on the following three service categories: IMS based multimedia service (voice, video etc), priority EPS bearer services (PS data without IMS interaction) and CS Fallback. Common issues for multiple service categories should be resolved by single solution to limit the amount of overall functionality and to avoid complexity. The basic eMPS, i.e. priority handling of IMS based multimedia service, EPS bearer services and CS Fallback have completed in Rel‑10. In Rel‑11, Single Radio Voice Call Continuity (SRVCC) from LTE to UTRAN/GERAN/1xCS will be investigated based on Rel‑10 SRVCC specification. The result of the analysis should be suitable as a basis for normative MPS specification work. The scope of the MPS part is to further investigate: - The signalling and procedures for identifying priority and authorizing the usage of priority service. - The required priority attributes used in enabling end-to-end priority marking and priority treatment during establishment, modification and release of an IMS based priority voice/video/data session. - The scenarios and capabilities for supporting priority EPS bearer data services. - The potential impacts on existing and relevant standard procedures in order to provide preferential treatment for MPS requests in the event of congestion. - Inter-working with other IMS and CS networks to provide an end-to-end priority service.

This Technical Report describes an IMS capable HNB SubSystem (the HNB and the HNB Gateway) as an optional capability of HNB that allows e.g. an operator to offload CS traffic to the IMS. The HNB and HNB Gateway are described in TR 23.830 [5], and the capabilities of these network elements are assumed by this TR. To achieve this and to satisfy the related requirements and use cases captured in TS 22.220 [2], the objective is to investigate the following: • an architecture to enable IMS capable HNB Subsystem to use the IMS for CS terminals using a corresponding equivalent IMS services (voice service in IMS Multimedia Telephony); • the impacts of the IMS capable HNB Subsystem to idle mode mobility for all supported UE types (e.g. IMS registration/de-registration); • service continuity at least in the direction from IMS capable HNB Subsystem to macro network; • support for pre-Rel‑9 CS and IMS UEs when using IMS capable HNB Subsystem. The TR will analyze solutions for the related architectural issues and capture the conclusions.

The system enhancements to enable codec rate adaptation at voice call setup over E-UTRA was standardized in Rel-9 in TS 23.401 [2]. The scope of this document is to study and specify enhancements to existing codec selection and codec rate adaptation based on network loading conditions and operator policies over UTRA and E-UTRA. Potential enhancements are definition of the signalling and interfaces enabling: - To perform codec selection based on network loading conditions and operator policies during call establishment phase over both UTRA and E-UTRA; - To perform codec data rate adaptation (if possible for the selected codec and needed by the service) based on network loading conditions during call establishment phase over UTRA; - To perform codec data rate adaptation (if possible for the selected codec and needed by the service) for non-voice RTP-based services based on network loading conditions at call setup over E-UTRA; - To perform codec data rate adaptation (if possible for the selected codec and needed by the service) based on network loading indications during an on-going call over both UTRA and E-UTRA; - Support of codec rate adaptation by IMS Core Network entities (e.g., MGCF/MGW, IBCF/TrGW, etc.); - Setting of Maximum Bit Rate (MBR) to be greater than the Guaranteed Bit Rate (GBR) over E-UTRA. The solutions can be moved to normative specifications independently of each other once the study on the particular solution has been concluded.

This study intends to investigate the general problem of system enhancements for the use of IMS services in local breakout and optimal routeing of media. In particular the above issues will be addressed identifying - solutions for the home operator to control - whether the IMS user may connect to a PDN in the visited network, and - whether connections to PDNs provided from the home and visited network may exist in parallel; - solutions to enable the IMS network to be aware of whether local breakout can be invoked or not; - solutions to allow the home operator to determine which of the IMS sessions (for a given UE) can be handled in local breakout and which in home routed mode, and what information (e.g. operator's policies, customer's subscription profile, UE connectivity, and location of the remote end terminal/service) is needed for the decision; - solutions to allow the UE to concurrently use IMS services through local breakout and other IMS services through home routeing; - the feasibility of having the local breakout option in IMS service nodes: - is there a need for a P-CSCF at both PDN accesses? - if one P-CSCF is enough, what requirements are there for connectivity between the PDNs? - if methods are necessary to discover an additional P-CSCF in the visited network after the UE has moved to the visited network, even if the network-layer mobility mechanisms can sustain IP connectivity to the previously discovered P-CSCF in the home network; - the exact location of the decision point in the home network whether to use local breakout (application or delegated to IP-CAN); - solutions for SIP/SDP signalling related to the use of IMS services through local breakout. - interactions with network entities such as NAT (as specified in TS 23.228 [8]) when providing IMS services through local breakout; - interactions with and support of PCC to provide IMS services through local breakout; - security implications if there is need for multiple P-CSCFs per UE. Moreover: - describing a set of scenarios where the selection of an alternative media path (i.e., different to the signalling path) provides benefits to IMS operators by reducing the number of network entities in the media path; - providing requirements for suitable mechanisms to achieve optimal media routeing; - analysing the potential solution(s) to solve those scenarios in line with IMS procedures, while taking into account any impact of extensions required to existing functions/procedures (e.g., NAT, transcoding, Security, PCC, BCF, LI, etc.); - reducing the number of options for solving the same requirement and agree on a preferred solution. In the end this study will provide conclusions with respects to what further specification work is required in order to fulfil the requirements for the use of IMS services through local breakout and achieve optimal routeing of media.

The present document provides a study into the Core Network impacts for providing a solution for Local Call Local Switching. The document analyses and evaluates different solutions to determine the benefits provided compared to the identified impacts. Specific considerations are given to the following areas:- - Sending of correlation information between the two legs of the call to the BSS - Triggering to enable/release Local Call Local Switch (e.g. based on activation of Supplementary Services, etc.) - Support of existing Supplementary Services - Support of existing Lawful Intercept functionality - Impacts to the user plane handling on the A-interface - Impacts to the MSC-S – MGW Interface (Mc Interface) - Impacts to the MSC-S – MSC-S Interface (Nc Interface) The solution(s) considered for local call local switch should keep the core network impacts to a minimum, e.g. the impacts on the nodal functions, existing call flows, call establishment and call release. The contents of this report when stable shall determine the modifications to existing core network specifications.

This technical report intends to develop enhancements to Rel-9 IMS Service Continuity in TS 23.237 [2], specifically in the functional area of Inter-UE Transfer. The main objective is to provide enhancements to mobility of media flows of a session between different UEs (Inter-UE Transfer) with respect to the following aspects: - Extension of Inter-UE Transfer and Collaborative Session capabilities specified in Rel-09 to multiple UEs belonging to different IMS subscriptions under the same operator. - Establishment of a Collaborative Session at session setup. - Support for control of media components of a Collaborative Session by more than one UE simultaneously. - Transfer of control of a Collaborative Session. - Controller initiated media modification on a Controllee UE (e.g. video resolution). - Discovery of ongoing IMS multimedia sessions on different UEs. - Inter-UE Transfer initiated by the target UE when: - the target UE belongs to the Collaborative Session but it is not a Controller UE; - the target UE does not belong to the Collaborative Session and wants to join; - Inter-UE Transfer is performed without establishing a Collaborative Session. - Replication of an ongoing multimedia session from one UE on another UE. - Inter-UE Transfer between UEs connected to the IMS via an IP-CAN and ICS entities that provide interworking with UEs in the CS Domain. - Execution of MMTEL services for Collaborative Sessions. This document contains the results of an assessment of alternative architectures to support Inter-UE Transfer enhancements.

The objective of the feasibility study is to investigate a solution for supporting single radio the video call continuity from E-UTRAN/HSPA to UTRAN-CS based on the Rel-8/9 Single Radio Voice Call Continuity (SRVCC) architecture as specified in TS 23.216 [2] and TS 23.237 [3], and study the mechanisms to resolve the key issues. It is not expected that the SRVCC architecture will be modified unless any of the key issues cannot be resolved with the current architecture. The study will be performed to the scenarios where IMS session using bidirectional voice and synchronised video such as defined in TS 22.173 [4], originated in E-UTRAN/HSPA and the UE moves to UTRAN and continues the service over UTRAN in the CS domain. The video call continuity from E-UTRAN/HSPA to GERAN is not supported.
