Problems solved by technology

But in that case, when the RNC sends a paging message to the user, the paging message must carry the IP address
The IPv6 address has 128 bits, and transmission on the air interface will cause additional overhead
If the IP address is really used as the paging identifier, it means that the paging identifier is consistent globally, which is unnecessary and will cause management confusion

Embodiment Construction

[0048] TMGI can be generated by GGSN. The TMGI is passed to the SGSN by the GGSN when the SGSN applies for joining the MBMS multicast group for the first time. The RNC obtains the TMGI for a certain service when the RNC receives the MBMS notification from the SGSN, and the SGSN delivers it. When the UE joins the MBMS service multicast group, the SGSN specifies the TMGI of the service for it.

[0049] If TMGI is generated by SGSN, TMGI is generated when SGSN applies for joining MBMS group for the first time, and informs GGSN. If the GGSN does not save the TMGI for the service, then use the TMGI as the identifier of the service. If the GGSN has recorded the TMGI corresponding to the service, the GGSN will notify it in the response to the SGSN. Therefore, it is ensured that the TMGI for the same service in a pool is consistent, and the problem caused by the introduction of Iu-Flex is solved.

[0050] If the TMGI is generated by the SGSN, after the allocation is completed, the...

Abstract

The method includes the following steps: issuing message to SGSN when UE is joined to multicast group; replying TMGI containing this service to VE if SGSN record is added with MBMS; issuing message from SGSN to GGSN if the service record is not in SGSN and sending TMGI to SGSN by GGSN if TMGI is generated by GGSN; generating a TMGI for MBMS service after GGSN is joined into the group by GGSN if the service record is not in GGSN; transmitting TMGI to RNC when MBMS note is sent to RNC by SGSN and issuing service request to RNC by UE of which TMGI is included.

Description

technical field [0001] The present invention relates to multimedia broadcast / multicast service (hereinafter referred to as MBMS), in particular to a method for generating and distributing temporary mobile group identifiers. Background technique [0002] MBMS is a new service being standardized by the Third Generation Partnership Project (abbreviated as 3GPP). The MBMS service is a one-way point-to-multipoint service. The biggest feature of this service is that it can effectively utilize wireless resources and network resources. In this service, the multimedia data sent from the data source is sent to multiple users through the transmission network. This point-to-multipoint service can save network resources. MBMS services are mainly used in wireless communication network systems, such as Wideband Code Division Multiple Access (hereinafter referred to as WCDMA), Global System for Mobile (hereinafter referred to as GSM), and so on. The transmission of MBMS data basically goe...
