Specific implementation mode
For a better understanding of the technical solution of the present invention, being retouched in detail to the embodiment of the present invention below in conjunction with the accompanying drawings
It states.
It will be appreciated that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art obtained without creative efforts it is all its
Its embodiment, shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of measurement method of the quality of reception, referring to FIG. 1, it is carried by the embodiment of the present invention
The flow diagram of the measurement method of the quality of reception of confession；As shown in Figure 1, this approach includes the following steps：
Step 101, at least one change time window group of MBMS Control Channel is obtained；Each change time window group packet
Include at least one change time window.
Specifically, terminal can receive the system information of network equipment broadcast, the network equipment can with after Network Synchronization
To include：Base station, MBMS control units, radio network controller（Radio Network Controller, RNC）Deng；It is described
System information may include Physical Broadcast Channel（Physical Broadcast Channel, PBCH）And system information block, it should
System information block（System Information Block, SIB）May include SIB1, SIB2 and SIB13.Terminal is from PBCH
System wireless frame number can be obtained（System Frame Number, SFN）.Terminal can also continue to read SIB1, and foundation
The receiving time window of the SIB13 carried in SIB1 reads SIB13, and SIB13 includes the configuration information of MBMS Control Channel, institute
The configuration information for stating MBMS Control Channel includes：The change cycle of MBMS Control Channel, the repetition period of MBMS Control Channel, nothing
Line frame shifting amount and subframe mark etc..One region MBSFN can correspond to a MBMS Control Channel.
In the embodiment of the present invention, terminal can obtain the MBMS controls letter according to system wireless frame number and change cycle
At least one change time window group in road, specifically includes：First, terminal obtains starting radio frame number；The starting radio frame number
To meet the system wireless frame number of following formula：Change cycle=0 system wireless frame number mod, i.e.,：The system wireless frame number removes
It is equal to 0 with the remainder of the change cycle, that is to say, that if a certain system wireless frame number divided by the remainder of change cycle are equal to 0,
So the system wireless frame number can be used as starting radio frame number；Then, terminal is continuous later extremely according to starting radio frame number
The time domain length of a few change cycle, obtains a change time window group；I.e.：Terminal, should using the starting radio frames as starting point
It is exactly a change time window that continuous time domain length, which is the time-domain resource of a change cycle, after starting radio frames, continuously
At least one change time window can form a change time window group.
Wherein, may include at least one change time window in a change time window group, in a change time window group
The specific number of change time window can be pre-configured with, and terminal can also be sent to by signaling by the network equipment, for example, network
Equipment carries the number of change time window or the network equipment in a change time window group in system information and passes through MBMS
Control channel sends the number of change time window in a change time window group to terminal.
Wherein, MBMS Control Channel is repeatedly sent to less primary in a change cycle, and the period for repeating to send is exactly
Repetition period, for example, referring to FIG. 2, the schematic diagram of its change time window provided by the embodiment of the present invention, as shown,
Change cycle is 512 system wireless frames, and the repetition period is 128 system wireless frames, then MBMS is controlled in a change cycle
Channel needs to repeat to send 4 times, and the time-domain resource in entire change cycle is exactly a change time window.
Step 102, at least one subframe of each change time window is obtained.
Specifically, first, terminal according to the system wireless frame number, the repetition period and the wireless frame shifting amount,
The first radio frames of the carrying MBMS Control Channel in change time window are obtained, the first radio frames are to meet the system of following formula
Radio frames：
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 128, system wireless frame number mod128=64,
Then system wireless frame number can be 64,192,320 and 448, then it is 64,192,320 and that the first radio frames, which are system wireless frame numbers,
448 system wireless frame.
Secondly, terminal identify according to the subframe, is determined in above-mentioned first radio frames and is carried the of MBMS Control Channel
One subframe；Subframe mark can be subframe number, and subframe mark is used to indicate which subframe in the first radio frames can be
First subframe, for example, the first subframe can be subframe 1, subframe 2, subframe 3, subframe 6, subframe 7 and subframe in the first radio frames
8。
Preferably, terminal, can also be further in first son after the first subframe for determining carrying MBMS Control Channel
MBMS Control Channel is received on frame, and the candidate in the corresponding regions MBSFN of MBMS Control Channel is obtained from MBMS Control Channel
The end subframe of MBMS subframes, the period of MBMS scheduling channels and MBMS data channel indicates that terminal can be according to system wireless
The period of frame number and MBMS scheduling channels determines the second radio frames of carrying MBMS scheduling channels, then will be in the second radio frames
First subframe as the second subframe；For example, referring to FIG. 3, its change time window provided by the embodiment of the present invention
Subframe schematic diagram, as shown, the system wireless frame of following formula can will be met as the second radio frames：
Period=0 of system wireless frame number mod MBMS scheduling channels
Since there is MBMS data channel flexibility, not necessarily all candidate MBMS subframes to be all used for carrying MBMS data
Therefore channel can be indicated by the end subframe of MBMS data channel, carry out actual bearer in instruction terminal candidate's MBMS subframes
The subframe of MBMS data channel, therefore, terminal can be indicated according to the end subframe of MBMS data channel, in candidate MBMS subframes
The subframe of middle determining carrying MBMS data channel, which is exactly third subframe.
Step 103, the measurement that the MBSFN qualities of reception are carried out in each subframe, to obtain candidate measurement result.
Specifically, if terminal is in a step 102, the first subframe, the second subframe and third subframe are obtained, then terminal can be
In at least one of above-mentioned first subframe, the second subframe and third subframe subframe, each subframe obtains MBSFN RS；According to institute
The measurement that MBSFN RS carry out the MBSFN qualities of reception in the regions MBSFN is stated, to obtain candidate measurement result.Wherein, MBSFN RS
It is scrambled using the distinctive area identification progress in the regions MBSFN, which is also carried in above-mentioned SIB13.
Alternatively, if terminal is in a step 102, the first subframe is only obtained, then only progress MBSFN connects terminal in the first subframe
The measurement for receiving quality, the measurement without carrying out the MBSFN qualities of reception in the second subframe and third subframe are because of the second subframe
Subframe mark, the modulation coding scheme of MBMS data channel is all to obtain in the subframe of third subframe mark and third subframe
It can just be obtained after MBMS Control Channel, therefore, MBSFN receptions only be carried out in the first subframe of carrying MBMS Control Channel
The measurement of quality, without further obtaining the second subframe and third subframe, can simplify the MBSFN qualities of reception measurement procedure and
Terminal implementation complexity.
Wherein, the MBSFN qualities of reception include at least one in following information：
MBSFN Reference Signal Received Power（Reference Signal Receiving Power, RSRP）, MBSFN ginseng
Examine signal receiving quality（Reference Signal Receiving Quality, RSRQ）, MBSFN received signal strength indicators
（Received Signal Strength Indication, RSSI）, MBSFN channel qualities instruction（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）Packet number is missed with MBSFN.
Wherein, MBSFN RSSI refer to all receiving power on symbol or subframe, and MBSFN RSRQ can foundation
The ratio of MBSFN RSRP and MBSFN RSSI obtain, MBSFN SINR be equal to MBSFN RSRP divided by MBSFN RSSI and
The difference or MBSFN SINR of MBSFN RSRP is equal to MBSFN RSRP, MBSFN CQI and refers to missing in certain MBSFN blocks
MBSFN SINR under code check or modulation coding scheme, MBSFN miss packet number and refer to the number accidentally wrapped in a period of time.Its
In, terminal can obtain corresponding with the modulation coding scheme piece of error code of modulation coding scheme by the measurement of MBSFN BLER
Rate, and modulation coding scheme bLock error rate corresponding with the modulation coding scheme is stored, the tune can also be reported to the network equipment
Coding mode processed bLock error rate corresponding with the modulation coding scheme.In this way, different terminals does not have in identical MBSFN
It is measured in the case of BLER and obtains modulation coding scheme, but than relatively freely measuring obtained practical MBSFN according to itself
BLER obtains modulation coding scheme so that the realization method that terminal measures is more flexible.
Step 104, according to the candidate measurement result and each change time window, objective measurement is obtained.
Specifically, after terminal carries out the measurements of the MBSFN qualities of reception in each subframe, it can be according to the time of acquisition
Measurement result and each change time window are selected, average computation is carried out to candidate measurement result, it, can be with to obtain objective measurement
Improve measurement accuracy and stability.
In the embodiment of the present invention, terminal obtains target according to the candidate measurement result and each change time window
The method of measurement result may include following several：
The first：Candidate measure that terminal obtains at least one subframe according to each change time window is tied
Fruit obtains the average value of the candidate measurement result of each change time window, and the average value of candidate's measurement result is institute
State objective measurement；I.e.：Terminal only allows to belonging to the candidate survey at least one subframe in the same change time window
It measures result and carries out average computation, it is not possible to which the candidate measurement result in subframe to belonging to different change time window carries out average meter
It calculates, in this way, each change time window at least one change time window is corresponding to obtain an objective measurement.
Second：If the change time window group includes at least two change time windows, terminal is according to described in
The candidate measurement result obtained at least one subframe of each change time window at least two change time windows,
The average value of the candidate measurement result of the change time window group is obtained, the average value of candidate's measurement result is the target
Measurement result；I.e.：Terminal only allow to belong to same change time window group at least one subframe on candidate measurement result into
Row average computation, it is not possible to belong to the average computation of the candidate measurement result in the subframe of different change time window group, this
Sample, 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 change time window group includes at least two change time window groups, terminal obtains
Obtain status indicator；The status indicator instruction first state or the second state, status indicator can utilize bit or scrambler etc.
Mode realizes that for example, when bit is equal to 0, status indicator indicates first state, and when bit is equal to 1, status indicator indicates the second shape
State.
If the status indicator indicates first state, then it represents that when terminal can carry out receiving the change after status indicator
Between window candidate measurement result and the candidate measurement result of change time window before average computation, i.e., according to the state mark
The candidate measurement result of at least one change time window before knowledge and at least one described after the status indicator
The candidate measurement result of change time window, obtains the average value of the candidate measurement result, and candidate's measurement result is averaged
Value is the objective measurement.
If the status indicator indicates the second state, then it represents that terminal cannot carry out receiving the change after status indicator
The average computation of the candidate measurement result of time window and the candidate measurement result of change time window before is receiving instruction the
After the status indicator of two-state, it is not possible to which the candidate according at least one change time window before the status indicator surveys
The candidate measurement result of at least one change time window after result and the status indicator is measured, the candidate survey is obtained
The average value of result is measured, i.e., cannot carry out average computation to the candidate measurement result before and after acquisition status indicator.
Here, if terminal never has the status indicator for receiving the second state of instruction, terminal can be received always
The candidate measurement result of change time window after to status indicator is flat with the candidate measurement result of change time window before
Calculate, once receive the status indicator of the second state of instruction, then terminal cannot just carry out subsequent candidate measurement result with
The average computation of candidate measurement result before, but received after the status indicator that terminal can be to receiving the second state of instruction
Candidate measurement result carry out average computation, until terminal be received again by instruction the second state status indicator when until.
Further, for above-mentioned three kinds of methods, it is contemplated that MBMS Control Channel is with MBMS scheduling channels using identical
Modulation coding scheme, and the modulating-coding different from MBMS Control Channel and MBMS scheduling channels may be used in MBMS data channel
Mode, and hence it is also possible to by the time of the second subframe of the first subframe and carrying MBMS scheduling channels that carry MBMS Control Channel
Measurement result is selected, average computation is separately carried out with the candidate measurement result of third subframe of carrying MBMS data channel, i.e., to the
The candidate measurement result of one subframe carries out average computation with the candidate measurement result of the second subframe, measures the candidate of third subframe
As a result average computation is individually carried out.
Optionally, it after the measurement for having carried out the above-mentioned MBSFN qualities of reception, obtains the candidate of at least one subframe and measures
It as a result or after obtaining the change time window of above-mentioned physical layer or the average value of candidate measurement result in change time window group, can be with
Further by the average value in high level（Such as wireless heterogeneous networks（Radio Resource Control, RRC）Layer or media interviews
Control（Media Access Control, MAC）Layer）Further average treatment is carried out, also needs to introduce in high level at this time flat
Equal time window and average time window group, the average time window or average time window group of the high level can be greater than or equal to above-mentioned object
Manage the change time window or change time window group of layer, i.e., it is corresponding in the average time window to above-mentioned high level or average time window group
The measurement result of physical layer carries out further average treatment, obtains final measurement result, then preserves the final measurement
As a result, the measurement result that further this can also be reported final to the network equipment.
Preferably, after step 104, this method can also include：
Terminal judges the state of terminal；If the state of the terminal is Idle state, objective measurement described in terminal storage,
When the state of terminal is connected state, terminal can send the objective measurement to the network equipment；If the state of the terminal
For connected state, terminal sends the objective measurement to the network equipment.
