Abstract:
1. A method of mobility management in an Internet Protocol (IP) enabled wireless communication network, comprising the steps of: using IP multicast for data transport of a unicast session for a user equipment (UE) going into active mode connected to a communication gateway that is located between the UE and an infrastructure network; allocating an IP multicasting address for use in transporting data to the UE, wherein the IP multicasting address is an IP multicast address and not an IP unicast address; informing the communication gateway of the allocated IP multicast address; sending a control message from the communication gateway, which is located between the UE and the infrastructure network, to a router in the infrastructure network to configure the router to forward to the communication gateway IP packets addressed to the allocated IP multicast address; using in a network gateway the IP multicast address for sending user plane data downlink to the UE; and using the router in the infrastructure network to transport the user plane data to the communication gateway.
