MULTIMEDIA BROADCAST MULTICAST SERVICE SESSION STARTMETHOD AND SYSTEM THEREOF
First Claim
1. A Multimedia Broadcast/Multicast Service (MBMS) session start method, comprising:
- a Broadcast/Multicast Service Center (BM-SC) initiating a session start request message via a Gateway GPRS Support Node (GGSN) to a Serving GPRS Support Node (SGSN);
receiving the MBMS session start request message, the SGSN sending the MBMS session start request message to an element of a Radio Access Network (RAN); and
receiving the MBMS session start request message, the element of the RAN checking whether to establish a bearer plane for the MBMS session, if establishing, activating an MBMS bearer context and the element of the RAN establishing radio resources to the user equipment (UE).

Abstract
The present invention discloses a Multimedia Broadcast/Multicast service (MBMS) session start method and a system thereof. The MBMS session start method includes the steps of: an MBMS Center (BM-SC) initiating a session start request message via a GGSN to an SGSN; receiving the MBMS session start request message, the SGSN sending the MBMS session start request message to an element of a Radio Access Network (RAN); receiving the MBMS session start request message, the element of the RAN checking whether to establish a bearer plane for the MBMS session, if establishing, activating an MBMS bearer context and the RAN establishing radio resources to the user equipment (UE). The element of the RAN may be a BSC/RNC. The method and the system thereof make it possible to optimize the system performance, reduce the resource waste of the radio network, and lower the complexity of the system processing.

14. A system for starting the session of Broadcast/Multicast Service (MBMS) Service, comprising:
-
a Broadcast/Multicast Service Center (BM-SC);
a Gateway GPRS Support Node (GGSN) connected to the BM-SC;
a Serving GPRS Support Node (SGSN) connected to the GGSN;
an element of a Radio Access Network (RAN) connected to the SGSN; and
a User Equipment (UE) connected to the RAN;
wherein the BM-SC initiates a session start request message via the GGSN to the SGSN;
the SGSN receives the MBMS session start request message and sends the MBMS session start request message to the element of the RAN;
the element of RAN receives the MBMS session start request message, activates an MBMS bearer context and establishes radio resources to the UE if it is decided to establish a bearer plane for the MBMS session. - View Dependent Claims (15, 16, 17, 18, 19, 20)
