Technical field
Multimedia broadcast multi-broadcasting business (the MBMS that the present invention relates to be suspended, Multimedia Broadcast Multicast Service) counting technology, relate in particular to the method and system, MCE and the base station that start a plurality of MBMS counting processes in a kind of Long Term Evolution (LTE, Long Term Evolution) system.
Background technology
Along with the fast development of Internet and popularizing of large-screen Multi-featured Mobile Terminal, a large amount of Mobile data multimedia services and various high bandwidth multimedia service have appearred, such as video conference, television broadcasting, video request program, advertisement, online education, interactive game etc., this has satisfied the multiple services demand of mobile subscriber on the one hand, has also brought new business growth point for mobile operator simultaneously.These Mobile data multimedia services require a plurality of users can receive simultaneously identical data, compare with general data service, have the characteristics such as data volume is large, longer duration, delay sensitive.
In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rd Generation Partnership Project) multimedia broadcast multi-broadcasting business (MBMS has been proposed, Multimedia Broadcast Multicast Service), this business is a kind of technology that transmits data from a data source to a plurality of destination mobile terminals, realize sharing of network (comprising core net and Access Network) resource, improved the utilance of Internet resources (especially air interface resource).The MBMS business of 3GPP definition not only can realize classes of messages multicast and the broadcasting of plain text low rate, but also can realize broadcasting and the multicast of high-speed multimedia business, multiple abundant video, audio frequency and multimedia service are provided, this has complied with the trend of following Mobile data development undoubtedly, for the development of 3G provides better professional prospect.
At present, in the system of Long Term Evolution (LTE, Long Term Evolution) system version 9 (Release 9), introduced the MBMS technology, and in LTE version 10 (R10, Release10), be optimized.The MBMS business is carried in system needs the common transmission of control signal (being also referred to as the MBMS control signal) and user data (being also referred to as the MBMS business) to realize.Wherein, control signal will inform that receiving terminal (such as terminal, subscriber equipment (UE, User Equipment)) controls parameter accordingly, guides UE to go to receive its interested MBMS business (being corresponding user data) to corresponding position.
Wherein, control signal is by multicast control channel (MCCH in LTE R9, R10 system, Multicast Control Channel), Broadcast Control Channel (BCCH, Broadcast Control Channel) and MCH schedule information (MSI, MCH Scheduling Information) transmit; The MBMS business is to transmit by multicast service channel (MTCH, Multicast Traffic Channel).
MBMS control signal and MBMS business are transmitted with MBSFN zone (MBSFN Area), and MBSFN Area is comprised of a series of residential quarters, generally comprise one or more by the residential quarter under evolution base station node (eNB) control.Fig. 1 is the logical construction schematic diagram of existing MBSFN area, and as shown in Figure 1, this MBSFN zone (in circle) comprises 19 residential quarters, wherein eNB1 control residential quarter 1, residential quarter 2 ..., residential quarter 6; ENB2 control residential quarter 7, residential quarter 8 ..., residential quarter 13; ENB3 control residential quarter 14, residential quarter 15 ..., residential quarter 19.
Perhaps, eNB1 control residential quarter 1, residential quarter 2 ..., residential quarter 13, its small area 1, residential quarter 2 ..., residential quarter 6 belongs to MBSFN area 1, residential quarter 7, residential quarter 8 ..., residential quarter 13 belongs to MBSFN area 2, namely the different districts among the eNB1 belongs to different MBSFN area.
Consider in the prior art, in MBSFN Area, send control signaling and to use the MBSFN technology to carry out synchronized transmission (purpose is so that UE can obtain the corresponding gain that merges when receiving) with user data, each residential quarter sends identical data content at identical running time-frequency resource in the MBSFN Technology Need MBSFN area, so just need to carry out unified scheduling and planning to the resource of each residential quarter.Use at present many cell/multicasts coordination entity (MCE, Multi-cell/multicast Coordination Entity) network element to carry out United Dispatching and the planning of Radio Resource, specifically can be with reference to international standard 3GPP 36.300.
Fig. 2 is existing MBMS control system structural representation, as shown in Figure 2, in existing MBMS system, the network element relevant with MBMS has eNB, MCE, MBMS gateway (MBMS Gateway), broadcast multicast service center (BM-SC, Broadcast Multicast Service Centre) and mobility management unit (MME, Mobility Management Entity), wherein, BM-SC initiates (Session Start) as business, business stops (Session Stop), the network element that professional renewal (Session Updated) or MBMS business datum provide; MBMS GW sends to corresponding eNB with the MBMS business datum by the M1 interface; MBMS GW will send to MME by the chain of command information (for example Session Start message, Session Stop message, Session Updated message) that BM-SC generates by the Sm interface; MME transmits network element as one fully, the chain of command information exchange of MBMS GW transmission is crossed the M3 interface be transmitted to MCE; MCE sends to corresponding eNB with corresponding chain of command information; By such processing, eNB will obtain MBMS business datum and corresponding chain of command information.
MBMS is professional to be sent in order further to optimize, and industry has been introduced the UE upstream feedback mechanism, particularly, upstream feedback mechanism be mainly used in network side obtain each MBMS business interested/number of users (or UE number) that receiving; Network side is optimized the transmission of MBMS business by obtaining number of users, for example, hang up (suspension) interested/ receiving the few MBMS of number of users professional, recover (resumption) interested/to receive the many MBMS of number of users professional.Network side is interested in order to know/ receiving the UE quantity (or with/without) of certain MBMS business, can be by sending counting order (counting order), so that interested/UE that receiving this MBMS business carries out uplink feedback, informs that this UE receives the state of MBMS at present.Network side can with get access to the information (have for certain MBMS namely what are interested/ receiving UE number) of UE quantity by uplink feedback, be applied to hang-up or the recovery operation of this MBMS business; In other words, network side can decide according to the UE quantity information that uplink feedback gets access to this MBMS business whether to carry out the MBSFN transmission on eating dishes without rice or wine.
Fig. 3 is complete MBMS service counting flow chart, as shown in Figure 3, when the MBMS service needed is counted, these need to be counted the MBMS business be called and treat that counting is professional, professional, or MBMS is professional.
Step 1, at first professional (business in this specification unless otherwise noted for the counting for the treatment of of a MBSFN area of eNB configuration by a MBMS service counting request message (MBMS SERVICE COUNTING REQUEST) for MCE, refer to that all MBMS is professional), and every MBMS SERVICE COUNTING REQUEST message only can comprise the counting business for the treatment of of a MBSFN area, and professional sum is at most 16.
MBMS SERVICE COUNTING REQUEST message definition is as shown in table 1:
Table 1
Wherein MCCH Update Time definition is as shown in table 2:
Table 2
Be that MCCH Update Time shows eNB in the time of eating dishes without rice or wine to send the MCCH message (comprising MBMSCountingRequest message) of upgrading, the multiple of revising the cycle (MP, Modification Period) with MCCH represents.
Step 2, eNB sends MBMS service counting response message (MBMS SERVICE COUNTING RESPONSE message) response to MCE and receives the counting request that comes from MCE; If eNB is execution in step 1 correctly, then send MBMS service counting failed message (MBMS SERVICE COUNTING failure message) to MCE.
Step 3, eNB will send counting request (MBMSCountingRequest) message at the corresponding MCCH of this MBSFN area, UE is carried on MBMSCountingRequest message on the MCCH by reception, knows that eNB is adding up the number of users of some MBMS business.
Step 4, corresponding UE (be interested and/or receiving the UE that counts the MBMS business) feeds back to eNB by counting response (MBMSCountingResponse) message; The number of considering corresponding UE under the eNB may be a large amount of, so eNB will collect corresponding feedback information within a period of time, can be that a MCCH revises the cycle (MCCH Modification Period) during this period of time, such as 5.12 seconds or 10.24 seconds.
The MBMSCountingResponse message definition is as shown in table 3:
Table 3
As can be seen from Table 3, two (IE of key message unit are arranged in the MBMSCountingResponse message, Information Element): mbsfn-AreaIndex-r10 and countingResponseService-r10, i.e. MBSFN area index and MBMS counting service index.
Step 5 is finished the collection of UE feedback information as eNB, eNB will report corresponding statistics to MCE, and namely eNB sends MBMS service counting report the test message (MBMS Service Counting Results Report) to MCE.
Wherein, above-mentioned step 1 and step 2, adopt the M2 interface between MCE and the eNB, be used for starting MBMS service counting process, step 3 and step 4 adopt the Uu interface between eNB and the UE, be used for finishing eNB and configure the counting business for the treatment of at MCCH, UE receives and treats counting business and UE to eNB feedback count result, and step 5 adopts the M2 interface between MCE and the eNB, is used for eNB and reports count results to MCE.A complete MBMS service counting (MBMS Service Counting) process should comprise the start-up course of the MBMS service counting of step 1 and step 2, the counting process of the MBMS business of eating dishes without rice or wine in step 3 and the step 4, and the MBMS service counting result's of step 5 reporting process.That is to say, MCE has started a MBMS service counting process, and has obtained the count results of MBMS business, has just finished a MBMS service counting process.
Can find out by top analysis, the counting business for the treatment of that triggers as MCE belongs to a plurality of MBSFN area, and MCE must send many MBMS SERVICE COUNTING REQUEST message and count (the counting business for the treatment of that every request message only comprises a MBSFN zone); The counting business for the treatment of that perhaps triggers as MCE belongs to a MBSFN area but number of services during greater than 16, and MCE need to send many MBMS SERVICE COUNTING REQUEST information and count (every request message comprises maximum 16 business).That is to say, in many cases, when MCE receives when needing professional or a plurality of MBSFN zone of counting to need counting professional from upper level network element or from a plurality of (greater than 16) of operator configuration, MCE need to send many MBMS SERVICE COUNTING REQUEST message and count, and namely MCE need to start a plurality of MBMS SERVICE COUNTING processes.
The problem that exists at present comprise following some:
1, if MCE indication eNB starts a plurality of MBMS counting processes within a MCCH modification cycle, because the MBMSCountingResponse message that UE sends only comprises MBSFN area index and MBMS service index, rather than concrete ID value, therefore may cause eNB can't distinguish counting response message, as: it is mbsfn-AreaIndex-r10=000 (3bits that UE1 sends MBMSCountingResponse message, indicate MBSFN area 1) and countingResponseService-r10=0001 (4bits, indication MBMS counting service 2); It is mbsfn-AreaIndex-r10=000 (3bits that UE2 sends MBMSCountingResponse message, indicate MBSFN area 1) and countingResponseService-r10=0001 (4bits, indication MBMS counting service 3).And when UE1 and UE2 belong to eNB1, when eNB1 receives above-mentioned counting response message, can't correctly distinguish MBMS service. corresponding to counting response
If 2 because radio network problems or other faults, cause the count results of the business that has not feed back to MCE, according to existing standard, MCE can not determine then whether successfully this counting process;
3, (the part residential quarter of eNB1 belongs to MBSFN area1 if eNB1 belongs to MCE1 and MCE2, another part residential quarter belongs to MBSFN area2), owing to not having interface between MCE1 and the MCE2, MCE1 initiates the counting request at MBSFN area1, MCE2 initiates the counting request at MBSFN area2, UE1 is in MBSFN area1, it is mbsfn-AreaIndex-r10=000 (3bits that UE1 sends MBMSCountingResponse message, indicate MBSFN area 1) and countingResponseService-r10=0001 (4bits, indication MBMS counting service 2); UE2 is in MBSFN area 2, it is mbsfn-AreaIndex-r10=000 (3bits that UE2 sends MBMSCountingResponse message, indicate MBSFN area 2) and countingResponseService-r10=0001 (4bits, indication MBMS counting service 3).Because UE1 and UE2 belong to eNB1, when eNB1 receives above-mentioned counting response message, can't correctly distinguish MBSFN area corresponding to counting response and MBMS service.

When MCE need to start a plurality of MBMS service counting process, MCE sent MBMS service counting request message to a plurality of eNB under its control.
It is to be noted: the corresponding a plurality of MBMS counting of above-mentioned a plurality of MBMS counting processes request (MBMS Service Counting Request) message, MCCH Update Time value in each MBMS counting request message can not be identical, must use different values.
Can not correctly obtain MBMS Service Counting Request message content refers to, owing to network reason (such as link failure) or other reasons (such as hardware fault), may cause eNB can not be correctly decoded MBMS Service Counting Request message.
If eNB is correctly decoded MBMS Service Counting Request message, then send MBMS Service Counting Response response message to MCE.
ENB determines in the time of eating dishes without rice or wine to send counting request (MBMSCountingRequest) message according to the value of the MCCH Update Time in the MBMS counting request message.
ENB receives the MBMS counting request message of a plurality of MCE, and then eNB sends respectively corresponding counting request message on eating dishes without rice or wine.
The described MBMS of eating dishes without rice or wine counting request message sends by MCCH.
Interested and/or receiving the UE that counts the MBMS business and feed back to eNB by counting response (MBMSCountingResponse) message.
The number of considering corresponding UE under the eNB may be a large amount of, so eNB will collect corresponding feedback information within a period of time, is that a MCCH revises the cycle (Modification Period) during this period of time, such as 5.12 seconds or 10.24 seconds.
Finish the collection of UE feedback information as eNB, eNB will report corresponding statistics to MCE, that is: eNB sends MBMS service counting report the test message (MBMS Service Counting Results Report) to MCE.
Step 108, MCE determines to hang up or recover the MBSFN transmission of MBMS business according to the counting statistics result, and flow process finishes.
Described hang-up refers to the eNB deletion MBMS resource on eating dishes without rice or wine, and stops to send MCCH change notification, keeps the MBMS business contexts, keeps or leaves IP multicast group.
Described recovery refers to the MBMS resource of eNB on recovering to eat dishes without rice or wine, and recovers to send MCCH change notification, if leave IP multicast group then again add.
Step 109:eNB sends MBMS Service Counting Failure message to MCE.
Step 110:MCE judges whether the retransmission count request message, and if it is execution in step 111, otherwise execution in step 112.
If MCE receives the MBMS service counting failed message (MBMS service counting failure) of one or more eNB, represent that then MCE does not successfully start this MBMS service counting process, then MCE can:
A) MCE restarts this MBMS service counting process repeatedly, until success;
B) MCE restarts several times MBMS service counting process, if the failure would abandon;
C) MCE abandons this MBMS service counting process.

MCE2 sends MBMS Service Counting Request message, MCCH Update Time=N in MBSFN area2.
Step 302, eNB1 receives the MBMS counting request message of MCE1 and MCE2.
Described eNB 1 sends MBMS Service Counting Response message to MCE1 and MCE2 respectively, shows and correctly receives the MBMS counting request information.
Step 303, eNB1 is according to the sequencing of receiving MBMS counting request message, and judgement is eating dishes without rice or wine to send which bar MBMS counting request message, if receive first the MBMS counting request message of MCE1, then execution in step 304, otherwise execution in step 306.
It is to be noted: if eNB receives the MBMS counting request message of a plurality of MCE, and when requiring eNB within the same MCCH modification cycle, to finish the MBMS counting, eNB is according to the sequencing of the MBMS counting request message of a plurality of MCE that receive, only send the MBMS counting request message that first receives, ignore the follow-up MBMS counting request message that receives.
Certainly, also can be, the eNB sequencing according to the MBMS counting request message of a plurality of MCE that receive among the present invention, only send the current MBMS counting request message that receives, the MBMS that receives before ignoring counting request message.
Step 304, eNB1 is at the MBMS counting request message MBMSCountingRequest that eats dishes without rice or wine to send MCE1.
Step 305, the UE among the MBSFN area1 sends MBMS counting response message, and eNB adds up UE quantity and sends the count results report to MCE1, and flow process finishes.
Step 306, eNB1 is at the MBMS counting request message MBMSCountingRequest that eats dishes without rice or wine to send MCE2.
Step 307, the UE among the MBSFN area2 sends MBMS counting response message, and eNB adds up UE quantity and sends the count results report to MCE2, and flow process finishes.
The present invention has also put down in writing a kind of system that starts a plurality of MBMS counting processes, comprise MCE and eNB, because the present invention there is no improvement to the existing network architecture, and only be that wherein Network Element Function is improved, therefore, the system of a plurality of MBMS counting processes of startup of the present invention still can understand with reference to the existing network framework, as understanding with reference to the network architecture shown in Figure 2.Below the correlation function of improved network element is described in detail.
