FRAMEWORK FOR ACCESS NETWORK SELECTION IN 3GPP IMS

摘要

3GPP Release 6 system aims to support various and multiple IP-CANs (IP Connectivity Access Networks) for IMS service access. In this environment, overlapping of cell coverage between IP-CANs that use the different access technologies occurs. Therefore a subscriber needs to select the appropriate IP-CAN considering the supported QoS level, the charging policy, the requested service, and etc. In this paper, we propose the framework for access network selection in 3GPP IMS.
