Description
Technical field
The present invention relates to the multimedia broadcast multi-broadcasting business being suspended (MBMS, Multimedia Broadcast
Multicast Service) counting technology, a kind of more particularly to Long Term Evolution (LTE, Long Term Evolution) system
Start method and system, MCE and the base station of multiple MBMS counting processes in system.
Background technology
With the popularization of Internet fast development and giant-screen Multi-featured Mobile Terminal, there are a large amount of mobile datas
Multimedia service and various high bandwidth multimedia services, as video conference, television broadcasting, video request program, advertisement, online education,
Interactive game etc., this aspect meets the multiple services demand of mobile subscriber, while also brings new industry for mobile operator
Business growth point.The multiple users of these mobile data multimedia service requirements can receive identical data simultaneously, with general data
Business is compared, and has the characteristics that data volume is big, the duration is long, delay sensitive.
In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rd Generation
Partnership Project) propose multimedia broadcast multi-broadcasting business (MBMS, Multimedia Broadcast
Multicast Service), the business is a kind of technology that data are transmitted from a data source to multiple destination mobile terminals,
The shared of network (including core net and access network) resource is realized, improves Internet resources (especially air interface resource)
Utilization rate.The MBMS that 3GPP is defined can not only realize message class multicast and the broadcast of plain text low rate, and can also
Enough realize broadcast and the multicast of high-speed multimedia service, there is provided a variety of abundant video, audio and multimedia services, this is undoubtedly suitable
The trend of following mobile data development has been answered, better services prospect is provided for 3G development.
At present, in the system of Long Term Evolution (LTE, Long Term Evolution) system version 9 (Release 9)
MBMS technologies are introduced, and are optimized in LTE versions 10 (R10, Release10).MBMS carries in systems
The common transport of control signaling (also referred to as MBMS control signalings) and user data (also referred to as MBMS) is needed to realize.Its
In, control signaling will inform receiving terminal (such as terminal, user equipment (UE, User Equipment)) corresponding control parameter,
UE is guided to go to receive its MBMS interested (i.e. corresponding user data) to corresponding position.
Wherein, control signaling is by multicast control channel (MCCH, Multicast in LTE R9, R10 systems
Control Channel), BCCH (BCCH, Broadcast Control Channel) and MCH schedule informations
(MSI, MCH Scheduling Information) is come what is be transmitted；MBMS be by Logical Traffic Channels (MTCH,
Multicast Traffic Channel) come what is be transmitted.
MBMS control signalings and MBMS are transmitted with MBSFN regions (MBSFN Area), MBSFN
Area is made up of a series of cells, generally comprises the cell under one or more controls by evolution base station node (eNB).Fig. 1 is
Existing MBSFN area logical construction schematic diagram, as shown in figure 1, the MBSFN regions (such as in circle) include 19 cells, its
Middle eNB1 control cell 1, cell 2 ..., cell 6；ENB2 control cell 7, cell 8 ..., cell 13；ENB3 controls cell
14th, cell 15 ..., cell 19.
Or eNB1 controls cell 1, cell 2 ..., cell 13, wherein cell 1, cell 2 ..., cell 6 belongs to
MBSFN area 1, cell 7, cell 8 ..., cell 13 belong to MBSFN area 2, i.e. different districts in eNB1 belong to not
Same MBSFN area.
In view of in the prior art, being sent control signaling in MBSFN Area MBSFN technologies will be used with user data
Transmission (purpose is so that UE can obtain corresponding merging gain when receiving) is synchronized, MBSFN technologies need MBSFN
Each cell sends identical data content on identical running time-frequency resource in area, thus needs the resource to each cell
Carry out unified scheduling and planning.Use multiple cell/multicast coordination entity (MCE, Multi-cell/multicast at present
Coordination Entity) network element carries out the United Dispatching of Radio Resource and planning, specifically refer to international standard 3GPP
36.300。
Fig. 2 is existing MBMS control system architecture schematic diagrams, as shown in Fig. 2 in existing MBMS systems, it is related to MBMS
Network element have 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), processing business and updates (Session
Updated) or MBMS data provide network element；MBMS data is sent to accordingly by MBMS GW by M1 interfaces
eNB；MBMS GW by Sm interfaces by the chain of command information generated by BM-SC (such as Session Start message,
Session Stop message, Session Updated message) it is sent to MME；MME is entirely as a forwarding net
Member, the chain of command information that MBMS GW are sent is transmitted to MCE by M3 interfaces；Corresponding chain of command information is sent to phase by MCE
The eNB answered；By such processing, eNB will obtain MBMS data and corresponding chain of command information.
Sent to further optimize MBMS, industry introduces UE upstream feedback mechanisms, specifically, uplink feedback
Mechanism is mainly used in interested/number of users (or UE number) for receiving that network side obtains each MBMS；Network
Side optimizes the transmission of MBMS by obtaining number of users, for example, hang up (suspension) it is interested/ receive user
The few MBMSs of number, recover (resumption) it is interested/ receiving MBMS more than number of users.Network side is in order to obtain
Know it is interested/ receiving the UE quantity (or with/without) of some MBMS, (can be counted by sending counting orders
Order) so that it is interested/ receiving the MBMS UE carry out uplink feedback, inform that the UE receives MBMS shape at present
State.Network side can by got by uplink feedback UE quantity information (i.e. for some MBMS, how many is interested/
UE number of reception), hang-up or recovery operation applied to the MBMS；In other words, network side can be according to uplink feedback
The UE quantity informations got determine whether the MBMS carries out MBSFN transmissions on eating dishes without rice or wine.
Fig. 3 is that complete MBMS counts flow chart, as shown in figure 3, when MBMS needs to count, these are needed
Carry out counting MBMS and be referred to as business to be counted, or business, or MBMS.
Step 1, MCE passes through a MBMS Counting requests message (MBMS SERVICE COUNTING first
REQUEST) (business in this specification refers both to the business to be counted for being one MBSFN area of eNB configurations unless otherwise noted
MBMS), and every MBMS SERVICE COUNTING REQUEST message is only capable of waiting to count comprising MBSFN area
Number business, and the sum of business is preferably at most 16.
MBMS SERVICE COUNTING REQUEST message definitions are as shown in table 1：
Table 1
Wherein MCCH Update Time definition is as shown in table 2：
Table 2
That is MCCH Update Time show that eNB sends the MCCH message of renewal on eating dishes without rice or wine and (included
MBMSCountingRequest message) time, with MCCH change the cycle (MP, Modification Period) multiple table
Show.
Step 2, eNB sends MBMS counting response message (MBMS SERVICE COUNTING RESPONSE to MCE
Message) response receives the Counting requests for coming from MCE；If eNB can not be appropriately carried out step 1, sent to MCE
MBMS counts failed message (MBMS SERVICE COUNTING failure message).
Step 3, eNB will send Counting requests on the MCCH corresponding to the MBSFN area
(MBMSCountingRequest) message, UE are obtained by receiving the MBMSCountingRequest message being carried on MCCH
Know that eNB is counting the number of users of some MBMSs.
Step 4, corresponding UE (i.e. interested and/or receive the UE for carrying out counting MBMS) passes through counting response
(MBMSCountingResponse) message is fed back to eNB；Number in view of corresponding UE under eNB be probably it is substantial amounts of,
So eNB will collect corresponding feedback information within a period of time, this period can be a MCCH modification cycle (MCCH
Modification Period), such as 5.12 seconds or 10.24 seconds.
MBMSCountingResponse message definitions are as shown in table 3：
Table 3
From table 3 it can be seen that have in MBMSCountingResponse message two key message members (IE,
Information Element)：Mbsfn-AreaIndex-r10 and countingResponseService-r10, i.e. MBSFN
Area indexes and MBMS counting service indexes.
Step 5, when eNB completes the collection of UE feedback informations, eNB will report corresponding statistical result, i.e. eNB to MCE
MBMS count results report message (MBMS Service Counting Results Report) is sent to MCE.
Wherein, above-mentioned step 1 and step 2, using the M2 interfaces between MCE and eNB, counted for starting MBMS
Process, step 3 and step 4, using the Uu interfaces between eNB and UE, business to be counted is configured on MCCH for completing eNB,
UE receives business to be counted and UE to eNB feedback count results, and step 5 is using the M2 interfaces between MCE and eNB, for eNB
To MCE report count results.One complete MBMS, which counts (MBMS Service Counting) process, should include step
Rapid 1 and the start-up course that counts of MBMS of step 2, the counting process for the MBMS eated dishes without rice or wine in step 3 and step 4, with
And the reporting process of the MBMS count results of step 5.That is, MCE starts a MBMS counting process, and
The count results of MBMS have been obtained, has just calculated and completes a MBMS counting process.
By analysis above as can be seen that when the business to be counted of MCE triggerings belongs to multiple MBSFN area, MCE must
Beard and hair send a plurality of MBMS SERVICE COUNTING REQUEST message, and to be counted, (every request message only includes one
The business to be counted in MBSFN regions)；Or when the business to be counted of MCE triggerings belongs to a MBSFN area but number of services
During more than 16, MCE needs to send a plurality of MBMS SERVICE COUNTING REQUEST information, and to be counted, (every please
Message is asked to include most 16 business).That is, in many cases, when MCE is received from upper level network element or is come from
When the business or multiple MBSFN regions that multiple (being more than 16) needs of operator's configuration count need the business counted, MCE
Need to send a plurality of MBMS SERVICE COUNTING REQUEST message to be counted, i.e. MCE needs to start multiple MBMS
SERVICE COUNTING processes.
The problem of presently, there are include it is following some：
If the 1, MCE indicates that eNB starts multiple MBMS counting processes within a MCCH modification cycle, sent due to UE
MBMSCountingResponse message only includes MBSFN area indexes and MBMS service indexes, rather than specific ID
Value, it is thus possible to cause eNB to cannot be distinguished by counting response message, such as：UE1 sends MBMSCountingResponse message
Mbsfn-AreaIndex-r10=000 (3bits, instruction MBSFN area 1) and countingResponseService-r10
=0001 (4bits, instruction MBMS counting service 2)；UE2 sends MBMSCountingResponse message
Mbsfn-AreaIndex-r10=000 (3bits, instruction MBSFN area 1) and countingResponseService-r10
=0001 (4bits, instruction MBMS counting service 3).And when UE1 and UE2 belong to eNB1, when eNB1 is received
During above-mentioned counting response message, MBMS service. corresponding to counting response can not be correctly distinguished
If the 2nd, because radio network problems or other failures, the count results for the business for causing to have are not fed back to
MCE, according to existing specification, MCE then not can determine that whether the counting process succeeds；
The 3rd, if eNB1 belongs to MCE1 and MCE2 (eNB1 cell portion belongs to MBSFN area1, another part cell
Belong to MBSFN area2), due to not having interface between MCE1 and MCE2, MCE1 initiates Counting requests in MBSFN area1,
MCE2 initiates Counting requests in MBSFN area2, and for UE1 in MBSFN area1, UE1 sends MBMSCountingResponse
Message be mbsfn-AreaIndex-r10=000 (3bits, instruction MBSFN area 1) and
CountingResponseService-r10=0001 (4bits, instruction MBMS counting service 2)；UE2 exists
In MBSFN area 2, it is mbsfn-AreaIndex-r10=000 that UE2, which sends MBMSCountingResponse message,
(3bits, instruction MBSFN area 2) and countingResponseService-r10=0001 (4bits, indicate MBMS
counting service 3).Because UE1 and UE2 belong to eNB1, when eNB1 receives above-mentioned counting response message, Wu Fazheng
Really distinguish MBSFN area and MBMS service corresponding to counting response.

Embodiment
The basic thought of the present invention is that multiple cell/multicast coordination entity MCE can repair in a multicast control channel MCCH
Change and start two or more difference MBMS counting processes in the cycle, the different counting processes refer to MBMS Counting requests message
MBSFN area identifications difference or MCCH renewal times MCCH Update in MBMS SERVICE COUNTING REQUEST
Time is different.；When not receiving count results report within a period of time after MCE sends counting MBMS request messages, then MCE recognizes
Fail for counting process；When the counting MBMS request messages requirement that eNB is received completed within MCCH modification cycle it is multiple
During same count request process, eNB only handles the counting MBMS request messages being initially received or the MBMS being currently received meters
Number request messages, ignore follow-up Counting requests or Counting requests above described in same count process refer to that MBMS counts
MBSFN area identifications and MCCH renewal times MCCH in request message MBMS SERVICE COUNTING REQUEST
Update Time are identical..And after counting MBMS request messages are received, the MCCH in determines counting MBMS request messages
When Update Time values are less than the MCCH Update Time values in the counting MBMS request messages received before, abandon and work as
Before the counting MBMS request messages that receive.
In the present invention, MCE is a logic entity, and MCE can exist as a single network element or other
A part for network element；Same MCE refers to that same MCE in logic, i.e. MCE can be located in multiple network elements, but with identical
Mark；
It is sent in MCE in eNB MBMS Counting requests message, in addition to an activationary time, i.e.,：ENB updates
The time (MCCH Update Time) of MCCH message；MCCH Update Time are an absolute values, its span is 0~
255 integer, unit are the MCCH modification cycles；
In the present invention, within MCCH modification cycle starting multiple MBMS counting processes refers to：Changed in a MCCH
In cycle, MCE starts simultaneously to be sent multiple Counting requests message or sends multiple Counting requests message, the MCCH successively
Update Time identical can not refer to：MCCH Update Time in each Counting requests message are necessary for different values.
In the present invention, described a period of time is：MCCH Update Time×MP+T；Wherein MCCHUpdate Time are
Refer to MCCH Update Time, wherein MP that MCE is set in MBMS Service Counting Request message
(Modification period) refers to that MCCH is changed the cycle, MCE and the known MP of related eNB value；Wherein T refers to eNB
Statistics, the time for sending MBMS Service Counting Results Report, T can be according to network state or operator
Tactful value, such as：1s, 2s ..., 10s, N × MP any one, wherein N is integer, N=0,1,2 .., 255；MP is
MCCH changes the cycle；After the MCE thinks Counting requests procedure failure, MCE can be retransmitted or be stopped sending Counting requests message.
Unless otherwise instructed, the MP in this specification is the MCCH modification cycles.
Embodiment one
Fig. 4 is the method flow diagram of the multiple MBMS counting processes of startup of the embodiment of the present invention one, as shown in figure 4, originally showing
The method of the multiple MBMS counting processes of startup of example specifically includes following steps：
Step 101, MCE starts multiple MBMS counting processes.
When MCE needs to start multiple MBMS counting processes, MCE sends MBMS industry to multiple eNB under its control
Business Counting requests message.
It is to be noted that：Above-mentioned multiple MBMS counting processes correspond to multiple MBMS Counting requests (MBMS Service
Counting Request) message, the MCCH Update Time values in each MBMS Counting requests message can not be identical, must
Different values must be used.
Step 102, eNB judges whether correctly obtain MBMS Service Counting Request message contents,
If it is, performing step 103, step 109 is otherwise performed.
MBMS Service Counting Request message contents can not correctly be obtained to refer to, due to network reason (such as
Link failure) or other reasonses (such as hardware fault), eNB may be caused to be correctly decoded MBMS Service
Counting Request message.
Step 103, eNB sends MBMS Service Counting Response response messages to MCE.
If eNB is correctly decoded MBMS Service Counting Request message, MBMS is sent to MCE
Service Counting Response response messages.
Step 104, eNB is eating dishes without rice or wine to send MBMSCountingRequest message.
MCCH Update Times of the eNB in MBMS Counting requests message value, counted it is determined that being sent on eating dishes without rice or wine
Ask the time of (MBMSCountingRequest) message.
ENB receives multiple MCE MBMS Counting requests message, then eNB sends corresponding Counting requests respectively on eating dishes without rice or wine
Message.
The MBMS Counting requests message of eating dishes without rice or wine is sent by MCCH.
Step 105, UE sends MBMS counting responses (MBMSCountingResponse) message.
It is interested and/or receive carry out count MBMS UE pass through counting response
(MBMSCountingResponse) message is fed back to eNB.
Step 106, eNB receives MBMS counting responses, counts UE quantity.
Number in view of corresponding UE under eNB be probably it is substantial amounts of, so eNB will be collected within a period of time it is corresponding anti-
Feedforward information, this period are that a MCCH is changed the cycle (Modification Period), such as 5.12 seconds or 10.24 seconds.
Step 107, statistical result is sent to MCE by eNB.
When eNB completes the collection of UE feedback informations, eNB will report corresponding statistical result to MCE, i.e.,：ENB is to MCE
Send MBMS count results report message (MBMS Service Counting Results Report).
Step 108, MCE is determined to hang up according to counting statistics result or the MBSFN of recovery MBMS is transmitted, flow knot
Beam.
The hang-up refers to that eNB deletes the MBMS resources on eating dishes without rice or wine, and stops sending MCCH change notification,
Retain MBMS context, retain or leave IP multicast group.
It is described recovery refer to eNB recover eat dishes without rice or wine on MBMS resources, recover send MCCH change notification,
Rejoined if IP multicast group are left.
Step 109：ENB sends MBMS Service Counting Failure message to MCE.
Step 110：MCE judges whether retransmission count request message, if it is performs step 111, otherwise performs step
112。
If the MBMS that MCE receives one or more eNB counts failed message (MBMS service counting
Failure), then it represents that MCE does not start this MBMS counting process successfully, then MCE can be with：
A) MCE repeatedly restarts this MBMS counting process, until success；
B) MCE restarts several MBMS counting process, is abandoned if failure；
C) MCE abandons this MBMS counting process.
Step 111, MCE retransmission counts request message, step 102 is performed.
Step 112, MCE stops sending Counting requests message, and flow terminates.
Embodiment two
Fig. 5 is the method flow diagram of the multiple MBMS counting processes of startup of the embodiment of the present invention two, as shown in figure 5, originally showing
The method of the multiple MBMS counting processes of startup of example specifically includes following steps：
Step 201, MCE sends MBMS Service Counting Request message in M2 interfaces.
Step 202, eNB sends MBMS Service Counting Response response messages to MCE.
Step 203, MCE judges whether MBMS counting processes succeed, if it is, flow terminates, otherwise performs step
204。
Step 204, within a period of time, MCE is not received by MBMS Service Counting Results
Report message, then it is assumed that counting process fails.
Described a period of time is specially：MCCH Update Time×MCCH MP+T；Wherein MCCH Update Time are
Value in MBMS Service Counting Request message, MCCH MP are that MCCH is changed the cycle, and T is that eNB counts UE numbers
Amount and the time for sending count report, T can be according to network state or carrier policy values, such as：1s, 2s ..., 5s, N ×
MP etc. any one, wherein N is integer, N=0,1,2 ..., 255.
Step 205：MCE is retransmitted or sent new or stops sending MBMS Counting requests message.
Embodiment three
Fig. 6 is the method flow diagram of the multiple MBMS counting processes of startup of the embodiment of the present invention three, as shown in fig. 6, originally showing
The method of the multiple MBMS counting processes of startup of example specifically includes following steps：
Step 301, MCE1 sends MBMS Service Counting Request message, MCCH in MBSFN area1
Update Time=N.
MCE2 sends MBMS Service Counting Request message, MCCH Update in MBSFN area2
Time=N.
Step 302, eNB1 receives MCE1 and MCE2 MBMS Counting requests message.
The eNB 1 sends MBMS Service Counting Response message to MCE1 and MCE2 respectively, shows
It is properly received MBMS counting request informations.
Step 303, eNB1 judges eating dishes without rice or wine which bar sent according to the sequencing for receiving MBMS Counting requests message
MBMS Counting requests message, if first receiving MCE1 MBMS Counting requests message, step 304 is performed, otherwise performs step
306。
It is to be noted that：If eNB receives multiple MCE MBMS Counting requests message, and requires eNB same
When MBMS countings are completed in the MCCH modification cycles, eNB is suitable according to the priority of the multiple MCE received MBMS Counting requests message
