Problems solved by technology
[0044] Therefore, one of the purposes of the present invention is to solve or alleviate the data loss problem that may occur when the user terminal equipment UE newly joins the MBMS service
[0046] In order to achieve the above object, the present invention provides a kind of dedicated channel suitable for MBMS service that can solve or alleviate the data loss problem that may occur when the user terminal equipment UE newly joins the MBMS service, and solves or alleviates the RNC's frequent decision on point-to-point dedicated channel. The "ping-pong effect" problem caused by the mutual conversion between point-to-multipoint public channels can reduce the signaling interaction process inside the system, thereby reducing the system load. Point-to-point mode and point-to-multipoint mode conversion method

Embodiment Construction
[0074] The present invention relates to an MBMS service suitable for MBMS service, which can solve or alleviate the problem of data loss that may occur when a user terminal equipment UE newly joins the MBMS service, and solve or alleviate the RNC's frequent decision on point-to-point dedicated channels and The "ping-pong effect" problem caused by the mutual conversion between point-to-multipoint public channels reduces the signaling interaction process inside the system, thereby reducing the system load. Point-to-point mode and point-to-multipoint mode mutual conversion method ; In fact, it reduces or alleviates the problem of data loss that may occur when the user terminal equipment UE newly joins the MBMS service by advancing the actual establishment process of the common channel before deciding to establish the common channel; The process of releasing and reestablishing dedicated (public) channel resources during the mutual conversion to multipoint mode is replaced by the pr...

This invention is an exchange method of point to point and point to points in multimedia and multicast business. Probable data lost problem brought by the new enter of MBMS business into subscriber terminal equipment UE is lightened or solved. And the í‹ping pong effectíŒ brought by RNC incessant making of reciprocal transformation of point to point special channel and point to points special channel is also lightened or solved. Signal interactive processing in the system is reduced in order to reduces the reciprocal transformation process of point to point and point to points of system load. The data lost problem brought by the new enter of MBMS business into subscriber terminal equipment UE is reduced by moving up the actual building process of common channel to the determination of building common channel. The goal of lightening or reducing í‹ping pong effectíŒ is achieved by replacing the release and rebuild process of special (common) channel resources brought by the reciprocal transformation of point to point special channel and point to points by parking emission and recovery emission process of the special (common) channel.
Description
technical field [0001] The present invention relates to multimedia broadcast and multicast service (hereinafter referred to as MBMS), in particular to a mutual conversion method between a point-to-point service data transmission mode and a point-to-multipoint service data transmission mode in MBMS. Background technique [0002] MBMS is a new service for which relevant standards are being formulated in the third generation mobile communication system partnership project for standardization. The MBMS service is a one-way point-to-multipoint service (that is, multimedia data broadcast from a single data source is sent to multiple users for reception through network transmission). The biggest feature of this kind of business is that it can effectively utilize wireless resources and network resources. MBMS services are mainly used in wireless communication network systems, such as broadband code division multiple access communication systems and global mobile communication syste...
