<p><P>PROBLEM TO BE SOLVED: To provide a system and method for appropriately managing call routing in a network environment including a CS network and an IMS network. <P>SOLUTION: A scheme is disclosed for managing call routing in a network environment including a CS network and an IMS network. When a call is originated by a UE device in the CS network, call information associated with the call is provided to a CCCF network node disposed in the IMS network. At the CCCF node, a pool of E.164 numbers are maintained as IMRNs which are mapped to or otherwise associated with called party numbers. The CCCF node dynamically allocates a select IMRN with respect to a called party number received from the UE device and returns it to the UE device. The dynamically allocated IMRN is then utilized for routing the call towards the called party. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
