Method for providing broadcast multicast service to users

Abstract

This invention relates to user broadcast business method, which comprises the following steps: sending the broadcast set business requirement to first belonged broadcast business center; the said first business center provides user with broadcast business requirement re-positioning to second broadcast business center; the said business center receives user business requirements to provide user broadcast business.

Description

technical field [0001] The invention relates to multicast technology in the communication field, in particular to a method for providing broadcast and multicast services to 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 multicast / broadcast from Rel-...

Problems solved by technology

Therefore, under normal circumstances, users can only obtain multicast services in their home BM-SC, but in some special cases, the multicast service provided by only one BM-SC of the user's home network cannot meet the actual business needs of users. Requirements, for example, in the case of roaming, users need to access MBMS services, which means that they need to return to the BM-SC in the home network for service activation (authorization), and receive MBMS data provided by the BM-SC in the home network, like image 3 shown

[0008] However, in the case of roaming, the MBMS service provided by the BM-SC in the home network cannot meet the needs of the user. All are local weather forecasts, not always the weather forecasts where they belong

However, the current MBMS framework cannot well support roaming in this situation, because the user always needs to access the BM-SC in the home network, and the BM-SC in the roaming network does not have the subscription information of the roaming user. The BM-SC in the roaming network cannot authorize the user; therefore, no matter where you are roaming, you will receive the weather forecast of the place you belong to

Therefore, in the case of roaming, the existing technology cannot realize the local provision of MBMS services

Similarly, other multicast services that require authorization by the home domain network of roaming users also have the problem that the visited network cannot directly provide multicast services locally

[0009] To sum up, the existing implementation methods for providing multicast services to users are limited to the provision of multicast services to users by the home BM-SC in the user's home network, and the effectiveness of providing services to users is limited to the home network. (for example, in the case of user roaming), it cannot meet the actual multicast service requirements of the user.
