Problems solved by technology

Because MBMS services are numerous, such a network design will inevitably cause these useless session start messages to cause signaling impacts on some RNC and SGSN nodes, so that relevant network nodes need to analyze and sort out some useless signaling
At the same time, GGSN and SGSN nodes are required to support these irrelevant services, occupying the bearer plane resources between GGSN and SGSN, and between SGSN and RNC, bringing unnecessary signaling load to RNC and SGSN nodes, and increasing network load and cost

Embodiment 1

[0070] In this embodiment, it is assumed that the service area of ​​operator A is area B, and area B includes n sub-areas B1, B2, . . . , Bn. In network planning, one SGSN is set for each sub-area Bi. In this embodiment, operator A provides an MBMS multicast service, which provides traffic information service only within the scope of sub-area B1, then, the general service area of ​​the MBMS multicast service is sub-area B1, and the corresponding SGSN is SGSN_B1. OAM configures the SGSN node list in the BM-SC that provides the MBMS multicast service. Since the MBMS multicast service is only provided within the sub-area B1, the SGSN node list configured by OAM has only one SGSN identifier, that is, SGSN_B1.

[0071] During the MBMS registration process, once an MBMS registration request is received from a GGSN, the BM-SC will add the identifier of the GGSN to the parameter "downstream node list" in its own MBMS bearer context, and respond with an MBMS registration response messag...

Embodiment 2

[0079] In this embodiment, it is assumed that the service area of ​​operator A is area B, and area B includes n sub-areas B1, B2, . . . , Bn. In network planning, one SGSN is set for each sub-area Bi. In this embodiment, operator A provides an MBMS multicast service, which provides traffic information service only within the scope of sub-area B1, then, the general service area of ​​the MBMS multicast service is sub-area B1, and the corresponding SGSN is SGSN_B1. OAM configures the SGSN node list on the GGSN that provides the MBMS multicast service. Since the MBMS multicast service is only provided within the sub-area B1, the SGSN node list configured by OAM has only one SGSN identifier, that is, SGSN_B1.

[0080] During the MBMS registration process, if the GGSN receives a registration request message from the SGSN, the GGSN first judges whether the SGSN node list obtained through OAM configuration restricts the SGSN receiving the MBMS multicast service, that is, whether the SG...

Embodiment 3

[0084] In this embodiment, it is assumed that the service area of ​​operator A is area B, and area B includes n sub-areas B1, B2, . . . , Bn. In network planning, one SGSN is set for each sub-area Bi. The BM-SC saves the corresponding relationship between the SGSNs in the network and the geographic locations of their coverage areas. In this embodiment, operator A provides an MBMS multicast service, and the MBMS multicast service provides traffic information service only within the scope of sub-area B1. By comparing the geographical location of the area covered by the SGSN stored by the BM-SC with the geographical location of the sub-area B1, the BM-SC obtains that the SGSN serving the traffic information service area is SGSN_B1, and the SGSN node list only includes SGSN_B1.

[0085] The subsequent MBMS registration process and session initiation process are the same as those in the first and second embodiments above.

[0086] In the second implementation scheme, the OAM defin...

Abstract

The invention discloses a method to control dialog starting in MBMS. Wherein, configuring SGSN node list contained all service area to every business; then, GGSN acquires the list and determines whether admits SGSN have a special MBMS dialog in MBMS registration process or MBMS dialog starting process according to said list. This method can decrease unnecessary signaling load and network cost.

Description

technical field [0001] The invention relates to multimedia broadcast / multicast service (MBMS) session technology, especially a method for controlling the start of MBMS session. Background technique [0002] With the development of the third-generation mobile communication technology, the third-generation mobile communication can provide services with a higher data rate than the second-generation mobile communication, thereby supporting various business forms, such as: video calls, picture downloads, and high-speed Internet browsing and other services. Among them, one type of service is characterized by: it can be sent to all users in the wireless network who have customized the service at the same time, such as: sending weather forecasts, news clips, sports game highlights, and so on. Thus, the third-generation mobile communication introduces the concept of broadcast / multicast. [0003] As shown in Figure 1, for an intermediate node, no matter how many nodes are expected t...
