Problems solved by technology

Such a solution is somewhat similar to the early TV with only eight channels. Compared with the dozens or even hundreds of TV channels that TV stations can provide, it will greatly restrict users from watching more programs.
Moreover, it is very troublesome for users to activate MBMS services manually, and reduces user satisfaction; at the same time, due to the complexity of ordering, more services may not be selected, thereby reducing MBMS service providers and mobile network operators. operating efficiency

Embodiment Construction

[0074] The core idea of ​​the present invention is to expand the structure of MBMS_NSAPI, and enable users to activate more MBMS services at the same time by using the expanded MBMS_NSAPI.

[0075] In the present invention, the MBMS service activation process is as shown in Figure 6, including the following steps:

[0076] Step 601: SGSN sends a request MBMS context activation message RequestMBMS Context Activation to UE for requesting UE to activate an MBMS UE context, the message carries at least IP multicast address, APN, Linked NSAPI, transaction identifier (TI). Among them, the IP multicast address identifies the service that the UE needs to activate; TI is selected by the SGSN, and its value is a value that has not been used by other activated PDP contexts and MBMS UE contexts of the UE. Here, TI may be without extension or after extension.

[0077] Step 602: After creating an MBMS UE context, the UE sends an Activate MBMS Context Request to the SGSN, which includes: IP...

Abstract

This invention discloses a method to create bearing in MBMS. Wherein, during the activation and deactivation process for MBMS business, using extended MBMS_NSAPI to activate more than eleven MBMS bear businesses and avoid the complexity of hand operation. On this condition, it also uses extended TI mark to identify more than sixteen dual-direction information stream. There is another method in this invention to create bear in MBMS, wherein, during the activation and deactivation process for MBMS business, using extended MBMS_NSAPI, and replacing the MBMS_NSAPI and TI by special MBMS upper and lower message mark; then, it can not only activate more than eleven MBMS bear business, but also identifies more dual-direction information stream.

Description

technical field [0001] The invention relates to multimedia broadcast / multicast service (MBMS) technology, especially a method for realizing bearer establishment in MBMS. 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, such as node 10, no matter how many nodes are ...
