Sae application for mbms

A method in a first core network gateway for providing multimedia broadcast multicast service (MBMS) in a wireless communication network, wherein the network includes a broadcast multicast service center (BM-SC) node connected to the first core network gateway and a second core network gateway connected to the first core network gateway over an S5/S8 interface, said method comprising the steps of:

• receiving an MBMS session request from the BM-SC node;
• sending an MBMS session response to the BM-SC node;
• forwarding the MBMS session request message to the second core network gateway;
• and,
• receiving an MBMS session response message from the second core network gateway;
• wherein the MBMS session request and response messages each comprise an information field adapted to MBMS.

A core network gateway for providing multimedia broadcast multicast service (MBMS) in a wireless communication network, wherein the network includes a broadcast multicast service center (BM-SC) node connected to the first core network gateway and a second core network gateway connected to the first core network gateway, the core network gateway comprising:

• a receiver configured to receive an MBMS session request from the BM-SC node;
• a transmitter configured to send a MBMS session response to the BM-SC node;
• a transmitter configured to forward the MBMS session request message to the second core network gateway over an S5/S8 interface;
• and,
• a receiver configured to receive an MBMS session response message from the second core network gateway;
• wherein the MBMS session request and response messages each comprise an information field adapted to MBMS.
