Problems solved by technology

[0008] in In the network architecture shown in Figure 1, MBMS GW not only needs to implement MBMS data interaction with ENB, that is, implement user plane functions, but also needs to implement control signaling interaction with BM-SC and MCE , that is to realize the functions of the control plane, which does not conform to the consensus of separating the control plane and the user plane of the LTE / SAE network

Embodiment Construction

[0033] In order to make the purpose, technical solutions and beneficial effects of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0034] The system for providing MBMS service in the embodiment of the present invention includes: Broadcast Multicast Service Center (BM-SC), MBMS Control Plane Entity (mMME), and Evolved Base Station (ENB).

[0035] Among them, BM-SC is used to provide MBMS service and send MBMS session management control signaling;

[0036] The mMME is used to perform session management on the MBMS service provided by the BM-SC, maintain the MBMS bearer context according to the received session management control signaling, and distribute the session management control signaling to the ENB;

[0037] The ENB is configured to maintain radio resources and MBMS service bearers according to the received session ma...

Abstract

The embodiment of the invention discloses a system for providing a MBMS service, including BM-SC, mMME and ENB, wherein mMME performs the conversation management on the provided MBMS service, sends the conversation management control signalling according to the received conversation management control signalling to maintain the MBMS bearing context; ENB maintains the wireless resource and the MBMS service bearing according to the received conversation management control signalling. The embodiment of the invention also discloses a method for providing MBMS service, wherein mMME maintains the MBMS bearing context , to send the conversation management control signalling to ENB, according to the received conversation management control signalling; MBMS maintains the MBMS bearing context according to the received conversation management control signalling; ENB maintains the wireless resource and the MBMS service bearing according to the received conversation management control signalling. The system and the method of the embodiment avoid the network service ability restricting by MCE function.

Description

technical field [0001] The present invention relates to multimedia broadcast multicast service MBMS technology, in particular to a system and method for providing MBMS service. Background technique [0002] In a long-term evolution network (LTE, Long Term Evolved) or a system architecture evolution network (SAE, System Architecture Evolved), adopt figure 1 The network architecture shown provides MBMS services. like figure 1 As shown, the architecture includes: Broadcast Multicast Service Center (BM-SC), MBMS Gateway (GW, gateway), Multi-Cell / Multicast Coordination Entity (MCE) and Evolved Base Station (ENB). [0003] During the MBMS session establishment process, BM-SC is used to send a session start request (Session Start Request) to MBMS GW; after MBMS GW receives the session start request, if it can accept the MBMS service, it will reply the session start request to BM-SC Response (Session StartResponse), which carries MBMS GW downlink tunnel information, such as MBMS ...
