About This Item

 

Full Description

ETSI TS 123 237 specifies the architectural requirements and procedures for delivery of IMS Service Continuity.

TS 23.206 [3] is migrated to this specification.

The scope of the specification includes:
  • Access Transfer related functionality:
    • PS-CS Access Transfer;
    • PS-PS Access Transfer;
    • PS-PS Access Transfer in conjunction with PS-CS Access Transfer;
    • Adding and/or removing media flows to support service;
    • MSC Server assisted mid-call feature;
    • SRVCC session transfer of IMS emergency session.
  • Inter-UE Transfer related functionality:
    • Establishment and release of a Collaborative Session;
    • Addition of media flows to, modification of media flows in, and release of media flows from a Collaborative Session;
    • Transfer of media flows from one UE to another;
    • Transfer of the Collaborative Session Control with or without transfer of media flows;
    • Transfer of all media flows to a target UE without establishing a Collaborative Session;
    • Session discovery;
    • Inter-UE Transfer initiated by the target UE or by the SCC AS;
    • Replication of media flows by means of Inter-UE Transfer procedures;
    • Authorization and other aspects to support Inter-UE Transfer across multiple IMS subscriptions.
The solution is restricted to service continuity using IMS procedures, i.e. mobility mechanisms on the IP-CAN level are not within the scope of this specification.
