Problems solved by technology

However, in the MBMS UE context saved by the GGSN, NSAPI is not saved, and the GGSN cannot identify the MBMS UE context it owns through the NSAPI carried in the message, so the MBMS UE context cannot be deleted correctly

Embodiment Construction

[0061] In order to solve the problem that in the process of deactivating the MBMS multicast service, after the GGSN owning the MBMS UE context receives the delete MBMS context request message containing NSAPI sent by the SGSN, the GGSN cannot identify the MBMS UE context it owns through the NSAPI carried therein, The present invention further adds an identifier for identifying the MBMS UE context in the delete MBMS context request message sent by the SGSN, so as to realize the deactivation of the multicast / broadcast service.

[0062] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] see Figure 4 Shown, the specific process that realizes the specific embodiment of the inventive method is as follows:

[0064] Step 401: The UE sends an IGMP (Ipv) / MLD (IPv6) leave message to the GGSN through the default PDP context, thereby leaving a specific multicast service identif...

Abstract

This invention discloses a method for deexcitation in multimedia broadcasting / multicast business, which contains SGSN transmits content request information containing mark identifying MBMS.UE content to GGSN of MBMS.UE, GGSN deletes MBMS.UE content and transmits excitation indication information to BM-SC after receiving MBMS.UE content request information, then BM-SC deletes MBMS.UE and transmits confirmation message, GGSN transmits deletion of MBMS.UE content corresponding message to SGSN to confirm deexciting MBMS.UE content, SGSN deletes MBMS.UE content after receiving deleting message. Said invention can accurate and reliable deexcites to multimedia broadcasting / multicast business.

Description

technical field [0001] The invention relates to multicast services, in particular to a method for deactivating multimedia broadcast / multicast (MBMS) services. 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. Services such as video calls, picture downloads, and high-speed Internet browsing. One of the characteristics of one type of service is that the service can be sent to users who have subscribed to the service in the wireless network at the same time. For example, weather forecasts, news clips, sports highlights and so on. Utilizing the characteristics of simultaneous transmission of these services, the third generation mobile communication introduces the concept of multicast / broadcast. [0003] see figure 1 As shown, for an intermedi...
