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

[0072] From the perspective of existing NSAPI usage, in PTP mode, NSAPI is used to identify a user's service access point for data transmission at the third layer of GPRS, and together with the user's IMSI, it identifies a data transmission tunnel from UE to GGSN. But for the MBMS service bearer, the bearer from the BM-SC to the RNC only distinguishes the service, not the user. The RNC also establishes a radio access bearer (RAB) for each MBMS bearer service. This RAB can be mapped to multiple radio bearers (RB). These RBs can be point-to-point dedicated bearers for a single UE or for a cell. Point-to-multipoint (PTM) shared bearer for multiple UEs. Therefore, in the application of MBMS services, no matter whether the RNC is transmitting PTP or PTM downwards, there is no longer any difference between MBMS_NSAPI for each user, a RAB ID defined by a controlling RNC (CRNC), and RB IDs corresponding to different bearers. One-to-one correspondence. That is to say, MBMS_NSAPI no l...

Abstract

This invention discloses a method to create bearing in MBMS. Wherein, during the activation and deactivation process for MBMS business, using special MBMS context mark to replace MBMS_NSAPI and 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 of the invention to create bear in MBMS. During the activation and deactivation process for MBMS business, using special MBMS context mark to replace the MBMS_NSAPI and TI; 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] see figure 1 As shown, for an intermediate node, such as node 10, no matter how many nodes ar...
