Summary

Recommendation ITU-T Y.2040 describes the flow-based service continuity mechanism in a multi-connection environment. This Recommendation also covers scenarios, requirements, solutions, information flows and security. In the multi-connection environment, flow-based service continuity is the mechanism that allows the moving of IP flows from one access to another (target) access, thus minimising service disruption in the case of access loss, or when the access is no longer usable. Flow-based service continuity (FSC) includes two modes, the multi-connection user equipment (MUE) initiated flow-based service continuity mode and the network-initiated flow-based service continuity mode.
