MIGRATING EMBMS INTO A CLOUD COMPUTING SYSTEM

摘要

A method is executed by a multimedia broadcast multicast services gateway (MBMS- GW) to offload data plane traffic, where the data plane traffic is enhanced MBMS (e MBMS) downlink traffic for a data plane interface Internet Protocol (IP) multicast transport between the MBMS-GW and an enhanced node B (e Node B). The method includes allocating an IP multicast address and a common tunnel endpoint identifier (C-TEID) for an MBMS session between node B (e Node B) and a broadcast multicast service center (BM-SC). The method also includes configuring the at least one network element to match an IP address and a user datagram protocol (UDP) port of incoming data plane traffic, to modify the IP address and UDP port to the IP multicast address and associated UDP port, and to push a general packed radio service (GPRS) tunneling protocol (GTP) user data (GTP-U) header including the C-TEID onto the data plane traffic.
