Abstract:
A system for compressing an Internet Protocol (IP) header for a multimedia broadcast multicast service (MBMS) is provided. The system includes an access gateway and a plurality of cells, each of which has an enhanced node B (ENB). When the quantity of cells that will provide the MBMS is known to be one, execution of a packet data convergence protocol (PDCP)-based data compression function for the IP header occurs in the ENB of the one cell. When the quantity of cells that will provide the MBMS is not known to be one, execution of the PDCP-based data compression function occurs in the access gateway.
