Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of enhancing broadcasting, method for activating multicast service, system and service center.
Background technology
Multicast is a kind of technology that transmits data message from a data source to a plurality of targets.For at present increasing high-speed multimedia business, using multicast mode shared resource is a kind of inevitable trend.
At third generation partnership projects (3GPP, Third Generation Partnership Projects) in, wireless network has been introduced multimedia broadcast multicast services (MBMS, Multimedia Broadcast Multicast Service) technology, send identical data to a plurality of subscriber equipment (UE by multicast mode, UserEquipment), i.e. portable terminal.Broadcast multicast service center (BM-SC, BroadcastMulticast-Service Center) is used for being responsible for processing, the processing of user profile and the processing of data of MBMS flow process.
Wireless network provides in the MBMS process, the content of multicast service is sent to each network node by multicast mode, Node B (eNodeB) or radio network controller (RNC such as evolution, RadioNetwork Controller), network node is by sending the Temporary Mobile Group Identity (TMGI be used to indicate the multicast service content that needs transmit on broadcast channel, Temporary Mobile Group Identifier) gives UE, UE judges whether the TMGI that preserves among TMGI that described network node sends and the UE is consistent, the TMGI that preserves among the described UE is used to indicate UE to obtain the content of the multicast service of mandate, if the TMGI that preserves among the TMGI that described network node sends and the UE is consistent, represent that then UE has the right to add the multicast service that wireless network sends, therefore can adopt the MBMS carrying between UE and the multicast source, transmission has obtained the multicast service of mandate, if not, then transmit unwarranted multicast service between wireless network refusal UE and the multicast source.Wherein, the TMGI that preserves among the UE is that UE obtains by activating in the multicast service process.
In carrying out the invention process, the inventor finds that the user that prior art provides activates in the multicast service process, the mode of consulting in advance between user and the user place Virtual network operator, obtain the multicast service of mandate, BM-SC has obtained the content of the multicast service of mandate according to the user, provide the TMGI of the multicast service correspondence that obtains mandate to the user, so that multicast source to user's multicast data transmission the time, is judged whether the have the right multicast packet of receiving group source transmission of user.But, when multicast service is when being provided by external network, the user can't obtain the mandate of the multimedia broadcast multicast services that external network provides in advance, BM-SC can't know whether the user has obtained the mandate of the multimedia broadcast multicast services that external network provides, can't provide corresponding TMGI to the user at the multicast service of external network, cause the external network multicast source to user's multicast data transmission the time, the user can't receive the multicast service that external network provides.
Because the complexity of multicast is too high, 3GPP organizes and has defined a cover and strengthens broadcast technology, broadcast technology among its technical characterictic and the 3GPP MBMS is very approaching, its major technique is characterised in that, network is not broadcasted in the sub-district of no user, and can select suitable empty port load-supporting according to number of users.Such technical characterictic just requires access network node to know user's number in its sub-district, the related realization mode of multicast is in full accord among the implementation of prior art and the MBMS, the last service identifiers TMGI that preserves its hope reception of UE, when Access Network is prepared to begin to play the enhancing broadcasting service, issue the TMGI of this business correspondence, with to user number counting in its sub-district.UE judges whether this TMGI is consistent with the TMGI that himself preserves, if consistent, then according to a certain percentage to the access network node feedback, so that access network node knows that it covers general number of users down.
In carrying out the invention process, the inventor finds that the user that prior art provides activates in the enhancing broadcasting service process, and network is when carrying out release of service, and the TMGI that programme content is corresponding with it tells in the lump to terminal.But for the business that network-external provides, wireless network can't be its distribution T MGI in advance, causes terminal can't obtain TMGI in advance, so that the user can't receive the multicast service that external network provides.
In sum, the inventor finds that there are the following problems in the prior art: the Activiation method of the Activiation method of the multicast service that the employing prior art provides or enhancing broadcasting service, the user can't obtain the TMGI of the multimedia broadcast multicast services correspondence that external network provides in advance, can't receive the multicast service that external network provides.
