Description
Technical field
The present invention relates to the communications field, particularly, relate to message treatment method and device in multimedia broadcast-multicast service (Multimedia Broadcast Multicast Service the abbreviates MBMS as) system.
Background technology
In order to realize effective utilization of mobile network resource, multimedia broadcast-multicast service (Multimedia Broadcast Multicast Service abbreviates MBMS as) has been proposed.The MBMS technology is that a data source is sent the point-to-multipoint service of data to a plurality of users, and it has realized sharing of Internet resources (comprising mobile core network and access network resource), and especially interface-free resources shares.Third generation mobile gpp (3rd Generation partnershipproject; Abbreviating 3GPP as) MBMS of definition not only can realize the classes of messages multicast and the broadcasting of plain text low rate; But also can realize the multimedia service multicast and the broadcasting of two-forty, this has complied with following mobile data Development Trend undoubtedly.
MBMS SFN (MBMS Single Frequency Network; Abbreviating MBSFN as) technology is a kind of technology that can improve the professional availability of frequency spectrum of MBMS; It requires the identical wireless signal of all adjacent base station synchronized transmissions; Subscriber equipment (UserEquipment abbreviates UE as) can be regarded as multipath signal with the signal from different base station.Make public physic channel transmit broadcasting service and obtain bigger signal gain, thereby improve professional service quality (Quality of Service the abbreviates QoS as) performance of MBMS.The MBSFN retaining zone is formed in one group of sub-district of the professional wireless signal of synchronized transmission MBMS, and these sub-districts are called the MBSFN sub-district.Sub-district in the MBSFN retaining zone, the wireless signal that synchronized transmission is identical.
The MBMS business is the service towards the whole network, and same MBMS business possibly be based upon on the different distribution network element nodes.Like this,, also need synchronized transmission MBMS service signal in the internodal sub-district of different distributions network element, otherwise, just possibly can not get receiving gain during UE receiving system message, and possibly cause strong same frequency to disturb.
In the existing 3GPP agreement; Radio network controller (Radio Network Controller; Abbreviate RNC as) or Node B add (Node B+) and receiving MBMS session that core network element sends when beginning message (MBMS Session Start); Respond the MBMS session according to disposition and begin response (MBMS Session Start Response) message, perhaps the MBMS session begins failure (MBMS Session Start Failure) message.When responding MBMS Session Start Response, RNC, Node B+ and core network element are set up this professional Iu signaling and are connected, and select to set up or do not set up this professional Iu user plane bearer.When responding MBMS Session Start Failure; RNC, Node B+ and core network element are not set up this professional Iu user plane bearer and are connected with Iu signaling that should business; Simultaneously; In MBMS Session Start Failure message, carry cause information, be used to indicate the reason of core network element failure.
Fig. 1 shows and realizes the network architecture that the MBMS service synchronization is sent between network element in the correlation technique.
As shown in Figure 1, one group of access network element (comprising RNC or NodeB+) of accomplishing the transmission of MBMS service synchronization is divided into master control network element and slave element locations from function.Master control network element is accomplished the user plane processing of MBMS business datum, through the interface between master control network element and the slave element locations its user plane processing dateout and timestamp information is sent to each distribution network element.Master control network element here and slave element locations can be that RNC, high-speed packet access add the Node B (Node B+) under (High Speed Packet Access Plus abbreviates HSPA+ as) flat framework.
Between above-mentioned MBMS business network element in the synchro system; Have only master control network element to obtain the MBMS business datum from core net; Slave element locations need not obtain the MBMS business datum from core net, that is to say, slave element locations does not need to set up Iu User Plane with core network element and carries.
For non-MBMS was professional, each slave element locations was an independently logic entity, and master control network element is not participated in non-MBMS business operation.According to present agreement, there is MBMS UE Linking message, the effect of this message is to connect through the PS signaling of having set up, and a given UE is added/leaves the advisory RNC/NodeB+ of multicast service.Therefore, in this case, core net possibly connect through the PS signaling of having set up between core network and the slave element locations directly with MBMS UE Linking message, send to corresponding slave element locations, and master control network element is not understood for this processing procedure.
Summary of the invention
Consider exist in the correlation technique professional for non-MBMS, master control network element is not known the problem of the processing between slave element locations and the core net and is proposed the present invention.For this reason, the present invention aims to provide a kind of message treatment method and device, in order to address the above problem.
