Description
Technical field
The present invention relates to the communication technology, relate in particular to the method that multi-service receives.
Background technology
The crowd that the communication technology is benefited is more and more wider, but its business that provides is still based on phone and message.Fast development along with the internet, a large amount of multimedia services emerge, the some of them multimedia service requires a plurality of user terminals (User Equipment is called for short UE) to receive identical data, for example video request program, television broadcasting, video conference, online education, interactive game etc. simultaneously.On cable network, can adopt internetworking agreement multicast (IP multicast) and broadcast technology to realize described requirement at present.Because particular network structure, functional entity and wave point etc. that mobile communications network has are all different with wireline communication network, and mobile multi-media service is compared with general data service, have characteristics such as data volume is big, longer duration, delay sensitive, existing IP multicast and broadcast technology can not be directly applied for mobile communications network.
In order to effectively utilize mobile network resource, realize the application of multimedia service, third generation partner program (3rd Generation Partnership Project, abbreviation 3GPP) multimedia broadcast-multicast service (Multimedia Broadcast/Multicast Service is called for short MBMS) has been proposed.The purpose of described MBMS is to provide one to send the business of data from data source to a plurality of users in mobile communications network, i.e. point-to-multipoint service realizes that Internet resources share, and improves utilization rate of network resource, the interface resource of especially eating dishes without rice or wine.The MBMS business that 3GPP proposes can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and this has complied with the trend of mobile data development undoubtedly.
Described MBMS architecture as shown in Figure 1, wherein, broadcast multicast service center (BroadcastMulticast Service Center, be called for short BM-SC) be the mobile network feature entity newly-increased in order to support MBMS, it is the inlet of content supplier, be used for authorizing and initiating the MBMS bearer service, and plan transmits the MBMS content to schedule the mobile network.In addition, in order to support the MBMS business, at subscriber equipment, ALPURCOM grounding wireless access network (UMTS Terrestrial Radio AccessNetwork, be called for short UTRAN), the enhancing data wireless access network of Global Communications System and evolution thereof (GSM EDGE Radio Access Network, be called for short GERAN), GPRS serving GPRS support node (Serving GPRS Support Node, be called for short SGSN), increased the relevant function of described MBMS respectively on the gateway GPRS supporting node (GGSN) functional entitys such as (GPRS Gateway Support Node are called for short GGSN).
Described MBMS comprises multicast pattern and broadcast mode, because that multicast pattern and broadcast mode exist on business demand is different, operation flow separately is difference also.
Under the described broadcast mode, the flow process that the user receives certain MBMS as shown in Figure 2, in step 210, carry out service statement, service statement is equivalent to the advertisement done to described business, as notify the user on certain channel of certain time, to be about to the program that broadcasts by short message or alternate manner, notify the relevant information of user MBMS; Session begins in step 220, and BM-SC is ready for sending data; In step 230, carry out the MBMS service announcements, service announcements then is that notice UE can prepare to receive described business before business arrives, and specifically is to notify user MBMS broadcast data to begin transmission by radio network controller (Radio Network Controller is called for short RNC); In step 240, carry out data transmission procedure; Conversation end in step 250, BM-SC no longer send data, and then releasing bearing resource.
Because described multicast pattern needs user's corresponding multicast group of contracting, carry out activation of service, and produce corresponding charge information, so its operation flow is different with operation flow under the broadcast mode.As shown in Figure 3, in step 310, contract, set up the contact between user and the service supplier; Carry out service statement in step 320, carry out the user and add in step 330, promptly the user notification network prepares to receive the MBMS business; Step 340-370 does not repeat them here corresponding to step 220-250, and the user withdraws from step 380, and after withdrawing from, the user has been the member of MBMS multicast group no longer just.
Wherein, data transfer phase in broadcast mode business and multicast pattern business, MBMS transmits information between UTRAN and UE mode has two kinds of patterns: put multiple spot (Point to Multipoint is called for short PTM) pattern and point-to-point (Point to Point is called for short PTP) pattern.Wherein, the PTM pattern sends identical data by MBMS point-to-multipoint service channel (MBMS Point-to-MultipointTraffic Channel is called for short MTCH), and all add multicast service and can receive the broadcasting service users interest; Ptp mode sends data by Dedicated Traffic Channel (Dedicated Traffic Channel is called for short DTCH), has only a corresponding UE can receive described data.
In the prior art, when multiple business was concurrent, as speech business and MBMS business, or many MBMS were when taking place simultaneously, and UE carries out professional priority and selects, i.e. the business that selective reception priority is the highest, and UE can not receive multi-service simultaneously.Under some scene, the user may wish to receive the MBMS business when answering speech business, such as, the user is watching a mobile TV (MBMS business a kind of), just in time there is a phone, but UE is unwilling to miss described TV programme again when conversation, according to existing technology, if UE can only select a business to handle, this is because network only uses the bearing mode carrying MBMS business of PTM, and major part only has the UE of basic MBMS receiving ability and can not receive data on DCH and the FACH simultaneously, can't realize that like this multiple services of speech business and MBMS business receives simultaneously.
