Feasibility study on multimedia session continuity; Stage 2
This study intends to investigate the general problem of IMS-level multimedia session continuity, including potential enhancements to IMS specifications that can improve the multimedia session continuity experience. In particular, the following topics will be studied:
- Identification of session continuity scenarios;
- PS-PS session continuity;
- PS-PS session continuity in conjunction with PS-CS continuity;
- Session continuity between 3GPP and non-3GPP systems;
- Network-initiated Multimedia Session Transfer;
- Mobility of media components of a session between different terminals under the control of the same user;
- Coexistence and/or potential interactions with possible underlying mobility solutions defined by 3GPP. The solutions developed within this study should not have any impacts to underlying mobility solutions.
In the end this study will provide conclusions with respects to what further specification work is required in order to fulfil the IMS-level Multimedia Session Continuity requirements and improve the overall service continuity experience.
