The method comprises the following processing steps: the subordinate element location receives first information from the core element location, and the information content of the first information is reported to the main control element location, wherein the information content comprises the information of user equipment joining in/leaving from multimedia broadcast/multi-broadcast service. By the invention, the main control element location can know about the condition that the core element location transmits MBMS UE Linking information to the subordinate element location.
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.To be a data source send the point-to-multipoint service of data to a plurality of users to the MBMS technology, and it has realized sharing of Internet resources (comprising mobile core network and access network resource), and especially interface-free resources shares.The third generation mobile partner plans (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 the trend of following mobile data development undoubtedly.
MBMS single frequency network (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 considered as multipath signal with the signal from different base station.Make public physic channel transmit broadcasting service and obtain bigger signal gain, thereby improve service quality (Quality of Service the abbreviates QoS as) performance of MBMS business.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 may 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 receiving gain may be can not get during UE receiving system message, and strong co-channel interference may be caused.
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+ set up this professional Iu signaling with core network element 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 sends between network element in the correlation technique.
As shown in Figure 1, one group of access network element (comprising RNC or NodeB+) of finishing the transmission of MBMS service synchronization is divided into master control network element and slave element locations from function.Master control network element is finished user's face of MBMS business datum and is handled, and by the interface between master control network element and the slave element locations its user's face 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 insert the Node B (Node B+) that adds 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 does not need to obtain the MBMS business datum from core net, that is to say, slave element locations does not need to set up the Iu User Plane carrying with core network element.
For non-MBMS was professional, each slave element locations was an independently logic entity, and master control network element does not participate in non-MBMS business operation.According to present agreement, there is MBMS UE Linking message, the effect of this message is to connect by 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 may connect by 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 for non-MBMS business, 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.
