【Embodiment】
In order to be better understood from technical scheme, the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
It will be appreciated that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
The embodiment of the present invention provides a kind of measuring method of the quality of reception, refer to Fig. 1, the schematic flow sheet of the measuring method of its quality of reception provided by the embodiment of the present invention；As shown in figure 1, this method comprises the following steps：
Step 101, at least one change time window group of MBMS Control Channel is obtained；Each change time window group includes at least one change time window.
Specifically, terminal is with that after Network Synchronization, can receive the system information of network equipment broadcast, the network equipment can include：Base station, MBMS control units, radio network controller（Radio Network Controller, RNC）Deng；The system information can include Physical Broadcast Channel（Physical Broadcast Channel, PBCH）And system information block, the system information block（System Information Block, SIB）SIB1, SIB2 and SIB13 can be included.Terminal can obtain system wireless frame number from PBCH（System Frame Number, SFN）.Terminal can also continue to read SIB1, and read SIB13 according to the SIB13 carried in SIB1 reception time window, and SIB13 includes the configuration information of MBMS Control Channel, the configuration information of the MBMS Control Channel includes：The change cycle of MBMS Control Channel, the repetition period of MBMS Control Channel, wireless frame shifting amount and subframe mark etc..One MBSFN region can correspond to a MBMS Control Channel.
In the embodiment of the present invention, terminal according to system wireless frame number and change cycle, can obtain at least one change time window group of the MBMS Control Channel, specifically include：First, terminal obtains starting radio frame number；The starting radio frame number is the system wireless frame number for meeting below equation：System wireless frame number mod change cycle=0, i.e.,：The system wireless frame number divided by the remainder of the change cycle are equal to 0, that is to say, that if a certain system wireless frame number divided by the remainder of change cycle are equal to 0, then the system wireless frame number can be used as starting radio frame number；Then, time domain length of the terminal according at least one continuous change cycle after starting radio frame number, obtains a change time window group；I.e.：Terminal is using the starting radio frames as starting point, and continuous time domain length is exactly a change time window for the time-domain resource of a change cycle after the starting radio frames, and at least one continuous described change time window can constitute a change time window group.
Wherein, at least one change time window can be included in one change time window group, the specific number of change time window can be pre-configured with one change time window group, terminal can also be sent to by signaling by the network equipment, for example, the network equipment carries the number of change time window in a change time window group in system information, or the network equipment sends the number of change time window in a change time window group by MBMS Control Channel to terminal.
Wherein, MBMS Control Channel is repeatedly sent to less once in a change cycle, the cycle for repeating to send is exactly the repetition period, for example, refer to Fig. 2, the schematic diagram of its change time window provided by the embodiment of the present invention, as illustrated, change cycle is 512 system wireless frames, the repetition period is 128 system wireless frames, then MBMS Control Channel needs to repeat to send 4 times in a change cycle, and the time-domain resource in whole change cycle is exactly a change time window.
Step 102, at least one subframe of each change time window is obtained.
Specifically, first, terminal obtains the first radio frames of the carrying MBMS Control Channel in change time window, the first radio frames are the system wireless frame for meeting following formula according to the system wireless frame number, the repetition period and the wireless frame shifting amount：
The system wireless frame number mod repetition periods=wireless frame shifting amount
For example, as shown in Fig. 2 wireless frame shifting amount is 64, the repetition period is 128, System wireless frame number mod128=64, then system wireless frame number can be 64,192,320 and 448, then the first radio frames are the system wireless frames that system wireless frame number is 64,192,320 and 448.
Secondly, terminal is identified according to the subframe, and the first subframe of carrying MBMS Control Channel is determined in above-mentioned first radio frames；Subframe mark can be subframe number, and the subframe is identified for indicating which subframe can be the first subframe in the first radio frames, for example, the first subframe can be subframe 1, subframe 2, subframe 3, subframe 6, subframe 7 and the subframe 8 in the first radio frames.
It is preferred that, terminal is it is determined that after the first subframe of carrying MBMS Control Channel, further MBMS Control Channel can also be received in first subframe, and the end subframe instruction of candidate MBMS subframes, the cycle of MBMS scheduling channels and the MBMS data channel in the corresponding MBSFN regions of MBMS Control Channel is obtained from MBMS Control Channel, terminal can be according to system wireless frame number and MBMS scheduling channels cycle, it is determined that the second radio frames of carrying MBMS scheduling channels, then regard first subframe in the second radio frames as the second subframe；For example, Fig. 3 is refer to, the subframe schematic diagram of its change time window provided by the embodiment of the present invention, as illustrated, the second radio frames can be regard the system wireless frame for meeting equation below as：
Cycle=0 of system wireless frame number mod MBMS scheduling channels
Because MBMS data channel has flexibility, not necessarily all candidate MBMS subframes are all used for carrying MBMS data channel, therefore, it can be indicated by the end subframe of MBMS data channel, carry out the subframe of actual bearer MBMS data channel in instruction terminal candidate's MBMS subframes, therefore, terminal can be indicated according to the end subframe of MBMS data channel, the subframe of carrying MBMS data channel is determined in candidate's MBMS subframes, the subframe is exactly the 3rd subframe.
Step 103, the measurement of the MBSFN qualities of reception is carried out in each subframe, to obtain candidate's measurement result.
If specifically, terminal is in a step 102, obtaining the first subframe, the second subframe and the 3rd subframe, then terminal can be at least one subframe in above-mentioned first subframe, the second subframe and the 3rd subframe, and each subframe obtains MBSFN RS；The measurement of the MBSFN qualities of reception in MBSFN regions is carried out according to the MBSFN RS, to obtain candidate's measurement result.Wherein, MBSFN RS is scrambled using the distinctive area identification in MBSFN regions, and the area identification is also carried in above-mentioned SIB13.
Or, if terminal is in a step 102, the first subframe is only obtained, then terminal only carries out MBSFN in the first subframe The measurement of the quality of reception, without carrying out MBSFN in the second subframe and the 3rd subframe The measurement of the quality of reception, the modulation coding mode for being MBMS data channel in subframe mark, the subframe of the 3rd subframe mark and the 3rd subframe because of the second subframe can be just obtained after MBMS Control Channel is obtained, therefore, the measurement of the MBSFN qualities of reception is only carried out in the first subframe of carrying MBMS Control Channel, without further obtaining the second subframe and the 3rd subframe, MBSFN can be simplified The measurement procedure and terminal implementation complexity of the quality of reception.
Wherein, the MBSFN qualities of reception include at least one in following information：
MBSFN Reference Signal Received Power（Reference Signal Receiving Power, RSRP）, MBSFN Reference Signal Received Quality（Reference Signal Receiving Quality, RSRQ）, MBSFN received signal strength indicators（Received Signal Strength Indication, RSSI）, MBSFN channel qualities indicate（Channel Quality Indicator, CQI）, MBSFN Signal to Interference plus Noise Ratios（Signal to Interference plus Noise Ratio, SINR）, MBSFN bLock error rates（Block Error Ratio, BLER）Bag number is missed with MBSFN.
Wherein, MBSFN RSSI refer to whole receiving powers on symbol or subframe, and MBSFN RSRQ can be according to MBSFN RSRP and MBSFN RSSI ratio is obtained, and MBSFN SINR are equal to MBSFN RSRP divided by MBSFN RSSI and MBSFN RSRP difference or MBSFN SINR refers to the MBSFN under certain MBSFN bLock error rates equal to MBSFN RSRP, MBSFN CQI SINR or modulation coding mode, MBSFN miss the number that bag number refers to wrapping by mistake in a period of time.Wherein, terminal can pass through MBSFN BLER measurement, obtain modulation coding mode bLock error rate corresponding with the modulation coding mode, and modulation coding mode bLock error rate corresponding with the modulation coding mode is stored, modulation coding mode bLock error rate corresponding with the modulation coding mode can also be reported to the network equipment.So, different terminals is not used in identical MBSFN Measurement obtains modulation coding mode in the case of BLER, but obtains modulation coding mode than the actual MBSFN BLER relatively freely obtained according to itself measurement so that the implementation of terminal measurement is more flexible.
Step 104, according to candidate's measurement result and each change time window, objective measurement is obtained.
Specifically, terminal is carried out in each subframe after the measurement of the MBSFN qualities of reception, candidate's measurement result and each change time window that can be according to acquisition, and average computation is carried out to candidate's measurement result, to obtain objective measurement, measurement accuracy and stability can be improved.
In the embodiment of the present invention, terminal according to candidate's measurement result and each change time window, obtain the method for objective measurement can include it is following several：
The first：Candidate's measurement result that terminal is obtained at least one subframe according to each change time window, obtains the average value of candidate's measurement result of each change time window, the average value of candidate's measurement result is the objective measurement；I.e.：Terminal only allows to carry out average computation to belonging to candidate's measurement result at least one subframe in same change time window, candidate's measurement result in subframe that cannot be to belonging to different change time window carries out average computation, so, at least one change time window each change time window is corresponding to obtain an objective measurement.
Second：If the change time window group includes change time window described at least two, then terminal is according to the candidate's measurement result obtained at least one subframe of each change time window at least two change time window, the average value of candidate's measurement result of the change time window group is obtained, the average value of candidate's measurement result is the objective measurement；I.e.：Terminal only allow to belong to same change time window group at least one subframe on candidate's measurement result carry out average computation, the average computation of candidate's measurement result belonged in the subframe of different change time window group cannot be carried out, so, in at least one change time window group, each change time window group is corresponding to obtain an objective measurement.
The third：If at least one described change time window group includes at least two change time window groups, terminal obtains status indicator；The status indicator indicates first state or the second state, and status indicator can be realized using modes such as bit or scramblers, for example, when bit is equal to 0, status indicator indicates first state, when bit is equal to 1, and status indicator indicates the second state.
If the status indicator indicates first state, then represent that terminal can carry out receiving the average computation of candidate's measurement result and candidate's measurement result of change time window before of the change time window after status indicator, candidate's measurement result i.e. according at least one change time window after the candidate's measurement result and the status indicator of at least one change time window before the status indicator, the average value of candidate's measurement result is obtained, the average value of candidate's measurement result is the objective measurement.
If the status indicator indicates the second state, then represent that terminal cannot carry out receiving the average computation of candidate's measurement result and candidate's measurement result of change time window before of the change time window after status indicator, i.e. after the status indicator for second state that indicates is received, candidate's measurement result that cannot be according at least one change time window after the candidate's measurement result and the status indicator of the change time window of at least one before the status indicator, obtain the average value of candidate's measurement result, cannot average computation be carried out to candidate's measurement result before and after acquisition status indicator.
Here, if terminal never has the status indicator for receiving second state that indicates, then terminal can carry out receiving the average computation of the candidate's measurement result and candidate's measurement result of change time window before of the change time window after status indicator always, once receive the status indicator for second state that indicates, then terminal cannot just carry out the average computation of follow-up candidate's measurement result and candidate's measurement result before, but terminal can be to receiving second state that indicates status indicator after candidate's measurement result for receiving carry out average computation, untill when terminal is received again by the status indicator for second state that indicates.
Further, for above-mentioned three kinds of methods, identical modulation coding mode is used in view of MBMS Control Channel and MBMS scheduling channels, and MBMS data channel can use and be different from MBMS Control Channel and the modulation coding mode of MBMS scheduling channels, therefore, can also be by the first subframe for carrying MBMS Control Channel and candidate's measurement result of the second subframe of carrying MBMS scheduling channels, candidate's measurement result of the 3rd subframe with carrying MBMS data channel separately carries out average computation, average computation is carried out with candidate's measurement result of the second subframe to candidate's measurement result of the first subframe, candidate's measurement result to the 3rd subframe individually carries out average computation.
Optionally, after the measurement of the above-mentioned MBSFN qualities of reception has been carried out,, can also be further by the average value in high level in the candidate's measurement result for obtaining at least one subframe or the change time window for obtaining above-mentioned physical layer or change time window group after the average value of candidate's measurement result（Such as wireless heterogeneous networks（Radio Resource Control, RRC）Layer or media access control（Media Access Control, MAC）Layer）Carry out further average treatment, now also need to introduce average time window and average time window group in high level, the high-rise average time window or average time window group can be more than or equal to the change time window or change time window group of above-mentioned physical layer, i.e. to the measurement result of corresponding physical layer in above-mentioned high-rise average time window or average time window group, carry out further average treatment, obtain final measurement result, then the final measurement result is preserved, further the final measurement result can also be reported to the network equipment.
It is preferred that, after step 104, this method can also include：

5 base stations most start to belong to the MBSFN regions, provide MBMS jointly for the terminal in the MBSFN regions, terminal carries out the measurement of the MBSFN qualities of reception according to the measuring method of the above-mentioned quality of reception, and the objective measurement of acquisition is sent into the network equipment.If the network equipment finds that the MBSFN qualities of reception are very good, it then can suitably reduce the quantity for the base station that MBMS is participated in the MBSFN regions, 5 base stations before are for example reduced to 3 base stations, the base station 5 in the base station 4 and cell 5 in cell 4 can be removed the MBSFN regions, that is base station 4 and base station 5 will not be provided MBMS, and be to provide unicast service.
Base station 4 and base station 5 are removed behind the MBSFN regions, the area identification in MBSFN regions, MBMS Control Channel, MBMS scheduling channels and MBMS data channel etc. do not change, the change of i.e. above-mentioned base station number is transparent for terminal, terminal does not know the change of above-mentioned base station number, therefore terminal may proceed to carry out the measurement of the MBSFN qualities of reception, and objective measurement is reported into the network equipment, because before and after base station number changes, there is difference in the MBSFN qualities of reception, therefore, if candidate's measurement result before and after the change of above-mentioned base station number is averaging processing terminal, the inaccurate of objective measurement will be caused.
In order to solve the problem of front and rear objective measurement of base station number change is inaccurate, above-mentioned three kinds are provided in the embodiment of the present invention according to candidate's measurement result and each change time window, the method for obtaining objective measurement, for example, for the third method therein, before base station number changes, the network equipment sends status indicator to terminal, candidate's measurement result of candidate's measurement result of the subframe of change time window after status indicator and the subframe of change time window before cannot be carried out average computation by instruction terminal, so, candidate's measurement result before and after the change of base station number would not be averaging processing for terminal, so as to avoid the inaccurate problem of objective measurement after base station number changes.
It should be noted that, even if only allowing to carry out average computation to candidate's measurement result in the subframe in a change time window, also there will not be considerable influence to the precision of objective measurement, because the sub-frame number in a change time window is relatively more, therefore can also meet the required precision of MBSFN qualities of reception measurement.
