Fig. 4 is referred to, is that a kind of base station that the embodiment of the present application is provided disappears to user equipment (UE) broadcast transmission conversation end
The signaling diagram of breath.Detailed step is as follows：
Step S41：BM-SC 403 sends conversation end request to each MBMS GW 402 in cell.
Step S42：Each MBMS GW 402 terminates response to 403 feeding back conversation of BM-SC, and session ending request is sent out
Deliver to MME/SGSN 401.
MBMS GW 402 passes to all MME/SGSNs 401 related to this carrying conversation end request, and discharge with
The user plane resource of eNB 404 and MBMS Bearer Context.
Step S43：MME/SGSN 401 terminates response to 402 feeding back conversation of MBMS GW.
Step S44：MME/SGSN 401 sends conversation end request, eNB to eNB (evolved NodeB, base station) 404
404 to MME/SGSN 401 feeding back conversations terminate response.
MME/SGSN 401 is sent to all eNB 404, eNBs 404 related to this carrying conversation end request and feeds back
Conversation end response, MME/SGSN 401 discharges MBMS Bearer Context.
Step S45：ENB 404 sends IGMPv3Membership Report to MME/SGSN 401.
ENB 404 exits the IP multicast group of correlation.
Step S46：ENB 404 generates conversation end message, and broadcast transmission is to user equipment (UE) 405.
Conversation end message can be carried by independent frame, as one single signal, it is also possible to be carried on SC-MCCH
In the frame that control information is located, that is, each repetition period for being carried on each modification cycle is corresponded in subframe, i.e., eNB 404 is permissible
Session end is arranged on SC-N-RNTI, and (Single Cell Notification RNTI, it is wireless that single cell is notified
Network Temporary Identifier) the DCI 1C (Downlink Control Information 1C, the descending control information format that scramble
1C), using one therein instruction conversation end message.
Illustrate for the structure of the conversation end message place frame in the embodiment of the present application below.Conversation end message can
To take shown in 1 bit, such as Fig. 5 (a), conversation end message is located at first bit, and is represented with 1, naturally it is also possible to position
In other bits, shown in such as Fig. 5 (b), certain conversation end message can be represented with 0, such as shown in Fig. 5 (c).
Wherein, LSB (Least Significant Bit) represent least significant bit), MSB (Most Significant
Bit) represent highest significant position.
User equipment 302, for obtaining SC-MCCH in the repetition period corresponding subframe of the starting from current Modification Period
Control information, and parse the SC-MCCH control information；And when the conversation end for receiving base station transmission disappears
Breath, and obtain from the repetition period of the starting the SC-MCCH control information parsing failure when, successively respectively from described
The SC-MCCH control information is obtained in the follow-up repetition period of the repetition period of starting, and parse, until described in successfully resolved
SC-MCCH control information.
Assume that the modification cycle includes 3 repetition periods, and be referred to as repetition period of starting, the second repetition period and the successively
Three repetition periods, then " obtain SC-MCCH control successively respectively from the follow-up repetition period of the repetition period of the starting
Information, and parse, until SC-MCCH control information described in successfully resolved " refer to, first from the second repetition period corresponding subframe
Obtain SC-MCCH control information.And parse, if successfully resolved, stop, or the repetition week of the starting from next modification cycle
Interim acquisition SC-MCCH control information is simultaneously parsed, if parsing failure, obtains SC- from the third repeating cycle corresponding subframe
MCCH control information, if successfully resolved, can stop, or obtain from the repetition period of the starting in next modification cycle
SC-MCCH control information is simultaneously parsed.
Because the SC-MCCH control information for parsing includes SC- corresponding with MBMS ID of user equipment (UE)
MTCH service related information, now shows that base station still sends business datum, i.e. base station and user equipment (UE) for the user equipment (UE)
Session do not terminate, accordingly, it would be desirable to persistently obtain SC-MCCH control information, if in the SC-MCCH control information for parsing not
Including SC-MTCH service related information corresponding with MBMS ID of user equipment (UE), now show base station with user equipment
The session of UE is over, and can stop obtaining SC-MCCH control information.So user equipment (UE) is after successfully resolved, have
Two kinds of possibility, that is, stop or obtain from the repetition period of the starting in next modification cycle SC-MCCH control information and parse.
If as shown in figure 5, user equipment receives conversation end message in the modification cycle 3, but in the repetition period 31
The non-successfully resolved of the SC-MCCH control information of middle acquisition, now can obtain SC-MCCH control information simultaneously from the repetition period 32
Parsing, if the SC-MCCH control information successfully resolved for obtaining from the repetition period 32, the session persistence of user equipment (UE)
For t3, compared with prior art, session persistence reduces t1-t3.
Maximum terminates Session Time in advance and is in the case：MaxTime=MP*10 RP*10 (unit：Ms), i.e. session
The wireless frame end of 0～maxTime can be shifted to an earlier date, in the formula, MP refers to the number of the radio frames that a modification cycle includes
The number of the radio frames that a repetition period includes is referred to RP, the persistent period of each radio frames is 10ms.
In the data handling system that the embodiment of the present application is provided, base station can generate conversation end message, work as user equipment
After receiving the conversation end message, need to further determine whether to be oneself to need to terminate and the session between base station, now,
If the SC-MCCH control information parsing failure for obtaining from the repetition period of the starting in modification cycle, can be successively from follow-up
SC-MCCH control information is obtained in repetition period, and is parsed, until successfully resolved.With prior art only from the modification cycle
The repetition period of beginning obtains C-MCCH control information and compares, and obtains and parse the frequency of SC-MCCH control information due to improve,
Therefore the success rate of parsing SC-MCCH is improve such that it is able to which fast resolving goes out SC-MCCH control information such that it is able to enter one
Step determines whether it is oneself to need to terminate and the session between base station, such that it is able to terminate session in time.
In order to improve user equipment (UE) parse SC-MCCH control information success rate, above-mentioned user equipment secondary respectively from
SC-MCCH control information is obtained in the corresponding subframe of follow-up repetition period of the repetition period of the starting, and when parsing, specifically
For：
By at least one SC-MCCH control information of the parsing failure for obtaining, with the current SC-MCCH not parsed for obtaining
Control information carries out soft merging, obtains the SC-MCCH control information after merging.To the SC-MCCH control information after described merging
Parsed.
In order to improve the success rate for receiving SC-MCCH control information, base station is used when SC-MCCH control information is transmitted
Turbo chnnel coding produces multiple redundancy versions (RV), to using increasing in the different repetition periods in same SC-MCCH change cycle
The mode of amount redundancy carries out SC-MCCH control information transmission, i.e., the different repetition periods adopt different redundancy versions.Redundancy version
This (RV), will the redundant bit that generates of encoder generate 4 redundancy versions according to starting point is different, numbering is 0,1,2,3.SC-
Transmission sequence of the MCCH control information in the difference repetition period in same change cycle is 0,2,3,1, specifically according to the repetition period
In number, if any 5 repetition periods, redundancy versions order is 0,2,3,1,0, if only 2 repetition periods, redundancy versions
Order is 0,2.
Terminal unit, can be to the SC- of the different repetition periods in the same change cycle when SC-MCCH control information is received
MCCH control information carries out soft merging.Specifically, if first repetition period SC-MCCH control information decoding failure, will
The corresponding bit of SC-MCCH control information of the unsuccessful decoding for receiving is preserved in the buffer, when receiving the same modification cycle
During the corresponding bit of SC MCCH control information in second repetition period, with first repetition period SC-MCCH in caching
The corresponding bit of control information is decoded after carrying out soft merging again, if decoding failure again, is receiving same modification week
During the corresponding bit of SC-MCCH control information in the 3rd repetition period, by the SC-MCCH control in the 3rd repetition period
The corresponding bit of information bit corresponding with first repetition period SC-MCCH control information receiving twice before caching and the
The corresponding bit of SC MCCH control information in two repetition periods carries out further decoding after soft merging.The rest may be inferred, until SC-
MCCH control information successfully decoded.
Add when SC-MCCH control information is transmitted within the different repetition periods in same change cycle by base station redundancy letter
The incremental redundancy transmission method of breath, terminal unit is decoded using soft merging when receiving, and can correct a part of SC-MCCH control
The corresponding error bit of information processed, so as to improve the probability for being properly received SC-MCCH control information.
It is understood that the SC-MCCH control information in each repetition period in the same modification cycle is all identical
, by each identical but the SC-MCCH control information of non-successfully resolved, with the current SC-MCCH control not parsed for obtaining
After information carries out soft merging, the SC-MCCH control information after to merging is parsed, and can greatly improve parsing SC-MCCH control
The success rate of information processed.
Certainly, user equipment can also only parse the SC-MCCH control information not parsed of current acquisition every time.
It is understood that user equipment is additionally operable to：As the SC- that each repetition period obtains in the same modification cycle
When MCCH control information is all parsed unsuccessfully, SC-MCCH control is obtained successively respectively from each repetition period in next modification cycle
Information processed, and parse, until successfully resolved SC-MCCH control information.
User equipment (UE) represents the session of the user equipment (UE) and base station after conversation end message is received, not and just ties
Shu Liao, because base station is when conversation end message is sent, is broadcast transmission, when the conversation end of some user equipment (UE)
Afterwards, base station all can broadcast transmission conversation end message, i.e., after user equipment (UE) receives conversation end message, may be strictly from
Oneself should terminate session, it is also possible to which other users equipment UE needs to terminate session.Now user equipment can be also used for：When
When success parses SC-MCCH, judge in the SC-MCCH, whether to include SC-MTCH business phase corresponding with the user equipment
Pass information；When SC-MTCH service related information corresponding with the user equipment is not included, conversation end is determined.
Optionally, user equipment can be also used for：When including SC-MCCH control information corresponding with the user equipment
When, still only from the repetition period of the starting in modification cycle corresponding subframe, SC-MCCH control information is obtained, and parse.From
And the number of times that user equipment is frequently obtained and parses SC-MCCH control information can be reduced, the electric energy of user equipment is saved, is provided
The processing speed of user equipment.
User equipment is additionally operable to：When the conversation end message is not received, when in the repetition period from the starting
