Embodiment Construction

[0047] In this embodiment, the multimedia broadcast / multicast service (MBMS) in the multicast service is taken as an example for illustration.

[0048] Since there is no interface between the BM-SC in the roaming network and the BM-SC in the user's home network in the prior art, the BM-SC in the roaming network cannot obtain the user's authorization from the BM-SC in the user's home network Therefore, it is impossible to provide local MBMS services to roaming users who have subscribed to MBMS services. The present invention adds an interface between BM-SCs in each network, so that the BM-SC in the visited network where the roaming user is located can interact with the BM-SC of the home network, so as to realize the communication between the BM-SC of the visiting network and the roaming user. Provides multicast services.

[0049] As shown in Figure 4, interfaces are added between BM-SCs in each network. Therefore, in the case of roaming, it is located between the BM-SC in the ...

This invention discloses one broadcast business center and communication system.

Description

technical field [0001] The invention relates to multicast technology in the communication field, in particular to a method and a communication system for providing multicast services to roaming users. 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. For example, 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 simultaneously send information to users who have subscribed to the service in the wireless network. For example, sending weather forecasts, news clips, sports highlights, etc. Taking advantage of the simultaneous transmission of these services, the third-generation mobile communication system introduces the concept of multicas...
