Summary

Recommendation ITU-T Y.2041 describes a policy control mechanism in multi-connection. Recommendation ITU-T Y.2041 also covers scenarios, requirements, solutions and information flows.

Multi-connection architecture is designed for heterogeneous networks, has the ability to provide multi-connection user equipment (MUE) and networks the functionality to maintain more than one access network connection simultaneously. It controls policies, flows, quality of service (QoS), etc.

Policy control is useful or even necessary for multi-connection. Policy control determines how to use multiple access network connections. There can be several policies in multi-connection, such as those for QoS and service transfer. Recommendation ITU-T Y. 2041 provides a coordination mechanism to ensure that all policies work together in a coherent manner for multi-connection.
