Description
Technical field
The present invention relates to multimedia broadcasting and multicast service (being called for short MBMS), particularly the method for notifying user equipment service ending.
Background technology
Multimedia broadcasting and multicast service are to propose also carrying out a standardized new business by third generation partner plan (being called for short 3GPP).The MBMS business is a kind of business of unidirectional point-to-multipoint, and the maximum characteristics of this business are that it can effectively utilize Radio Resource and Internet resources.
For better the present invention will be described, Fig. 1 has described the system configuration of MBMS.Be description below to Fig. 1 MBMS system configuration:
The MBMS network configuration is based on GPRS (be called for short GPRS) core net, and increased new network element.101 broadcasting and multicast service center (being called for short BM-SC) are the professional control centres of MBMS system.102 Gateway GPRS Support Nodes (be called for short GGSN) and 103 Serving GPRS Support Nodes (abbreviation SGSN) have constituted the transmission network of MBMS business, for the transmission of data provides route.106 attaching position registers (being called for short HLR) are preserved and subscriber-related data, and services such as subscription authentication can be provided.104 UMTS Terrestrial radio access networks (being called for short UTRAN) provide Radio Resource for MBMS serves on the interface aloft.107 Iu represent the interface between wireless access network and the core net.105 subscriber equipmenies (being called for short UE) are the terminal equipments that is used for receiving data.The professional used Radio Resource of MBMS is not user's special use, but professional thus all users share.
According to the definition of existing MBMS business, a MBMS business can be made up of several sessions.For each session, when session began, network can wake UE up and add up the UE number by paging, decision radio bearer type (radio bearer of point-to-point radio bearer or point-to-multipoint) and relevant parameter.When conversation end, network will be notified UE, and UE can discharge the resource of relevant user plane, stops to monitor relevant Traffic Channel.Prior art has defined the method that announcement session begins and finishes in network.
In addition, in the prior art, what UE left a service groups employing is point-to-point mode.
Fig. 2 has described the method for leaving the MBMS business that UE initiates in the prior art.
In 201 stages, the UE decision no longer continues to receive the MBMS business, and sends request by Non-Access Stratum (being called for short NAS) message " MBMS context deexcitation request " to network.
In 202 stages, SGSN sends response message " MBMS context deexcitation acceptance " to UE.After UE receives response message, can discharge professional relevant resource, stop to receive the MBMS channel with MBMS.
Fig. 3 has described in the prior art, and the UE that network is initiated leaves the method for MBMS business.
In 301 stages, the professional receiving course of MBMS of certain UE of SGSN decision will stopping, it sends NAS message " MBMS context deexcitation request " to UE.
In 302 stages, after UE receives the request of SGSN, should discharge relevant MBMS resource immediately, stop to receive the MBMS business, and reply " MBMS context deexcitation acceptance " message to SGSN.
Can see that by top description the method that UE leaves the MBMS service groups in the prior art is all carried out in point-to-point mode.In the prior art, network notice UE leaves a business all to carry out in point-to-point mode, needs finishing alternately between UE and the network.But when the professional termination of MBMS, all UE need to leave the MBMS business, if at this moment adopt existing technology, at first need the RRC that sets up point-to-point to connect between UE and the network, to finish point-to-point Signalling exchange between UE and the SGSN.When number of users is a lot, does like this and must cause serious network congestion.In addition on the one hand, because some UE receives the MBMS business under idle pulley, setting up RRC in order to leave the MBMS business and connect, also is unscientific.
Summary of the invention
The new method that the purpose of this invention is to provide a kind of notifying user equipment service ending.
For achieving the above object, a kind of method of notifying user equipment service ending comprises step:
During certain MBMS service ending of upper layer network notice RNC, discharge in the RNC the professional relevant resource of MBMS therewith earlier, delete the professional business contexts of preserving of MBMS for this reason;
RNC sends the service ending indication to UE;
UE receives from professional termination of the MBMS of RNC and indicates, and UE discharges the resource of relevant this MBMS business in this locality, stop to receive relevant MBMS Traffic Channel, deletes the professional business contexts of preserving of MBMS for this reason.
UE leaves the method for MBMS business, UE when the present invention proposes the termination of MBMS business
Release in this locality
Be placed with the pass resource, stop to receive relevant MBMS channel, do not need to set up RRC and connect, do not need to carry out alternately with network.All UE can leave the process of MBMS business at one time, mutually noninterfere, and efficient is very high.Because UE leaves MBMS when professional, do not need to carry out alternately, so avoided that network processes UE leaves congested that process causes in the prior art with network.

Embodiment
Describe embodiments of the invention with reference to the accompanying drawings in detail.Below only necessary component of the present invention is elaborated, can omit to some extent other parts in order to give top priority to what is the most important.
Fig. 4 is the embodiments of the invention flow charts, has described network notice UE service ending and has made
UE leaves the method for a service groups.
In 401 stages, RNC receives " business stops " message that SGSN sends, and knows that certain MBMS business will be through with.
In 402 stages, RNC stops the transmission of relevant MBMS channel immediately, discharges the relevant control plane and the resource of user plane, and discharges this professional MBMS context.
In 403 stages, RNC sends " end-of-dialogue " message to UE, and this is the last session of this MBMS business for notice UE, or comprises one " business stops indication " and indicate this MBMS business of UE to stop.
As the replacement scheme in 403 stages, in 404 stages, RNC can directly send " business stops indication " message to UE, indicates a MBMS business to stop.
