Abstract
The invention provides a GSM adjacent region measurement method and device in an LTE/TD-SCDMA business state. According to the offset between measurement GAPs and GSM frames, the measurement GAPs are grouped. By using the measurement GAPs of different groups, BSIC initial confirmation, BSIC re-confirmation or RSSI measurement is carried out. The problems of measurement GAP waste or uneven sampling points of RSSI measurement can be avoided. Furthermore, initial confirmation is divided into two steps of FCB and SB receiving.

5) measure GAP
The length of measurement GAP under LTE business state RRC_CONNECTED is all 6ms, but has two kinds of MGRP(Measurement Gap Repetition Period), be respectively 40ms and 80ms, specifically please refer to Fig. 5, it is the measurement GAP schematic diagram in LTE.
Under LTE business state, to the measurement of GSM adjacent area, need to complete following several measurements:
1) rssi measurement of GSM adjacent area
Under LTE business state, measure frequency number and be 32 to the maximum, at least 3 of the rssi measurement needs of each GSM community, measure sample values, measure sample values for these 3 and will be evenly distributed in measurement report cycle.
For non-DRX pattern, under RRC_CONNECTED state, the measurement report cycle of measuring GSM carrier wave RSSI is:
T
Measurement?Period,GSM=N
freq*480ms
Wherein, N
freq=N

Measure in GAP for one that LTE is corresponding and at least can measure 10 GSM carrier wave RSSI, each GSM carrier wave needs 3 to measure sampling point.If measure in report cycle and can not obtain desired measurement number of samples at one, can not measure obtaining the GSM carrier wave of enough number of samples in ensuing measurement report cycle.
For DRX pattern, measure the measurement report cycle T of GSM carrier wave RSSI
measurement Period, GSMthe length (details can with reference to 3GPP TS 36.133-970 section 8.1.2.4.5.2.1) that depends on DRX cycle.Shown in table 0 specific as follows:
Table 0
2) BSIC of GSM adjacent area confirms
Under LTE business state, support at most the BSIC of 8 signal Qiang GSM communities to confirm, the BSIC of GSM adjacent area confirms to be divided into initial confirmation (InitBSIC) and heavily confirms (ReBSIC), when under non-DRX pattern or DRX pattern, DRX cycle is less than or equal to 40ms, the time requirement of InitBSIC and ReBSIC as shown in following table one, the carrier number of Number of carriers other than GSM(except GSM in table) refer to N

Table one
When under DRX pattern, DRX cycle is greater than 40ms:
1) 8 the strongest GSM adjacent area frequencies are by intensity order: every Nfreq*30s at least attempts InitBSIC 1 time, if all do not had successfully in Nfreq*60s, abandons this frequency, attempt time strong frequency;
2) maximum 8 GSM adjacent areas, at least will attempt ReBSIC 1 time every Nfreq*30s, if cannot ReBSIC in continuous 2 ReBSIC failures or Nfreq*60s, abandon this frequency.
Under some scene, also need to be enhancing BSIC and confirm (Enhanced BSIC verification), strengthen the Enh-InitBSIC of BSIC confirmation and the time requirement of Enh-ReBSIC and see the following form two, the carrier number of Number of carriers other than GSM(except GSM in table) be 0, i.e. N

freq, HRPD=0, and measurement GAP is the 40ms cycle.
Table two
While initially confirming due to BSIC, there is no timing relationship, need blind check, during the direct blind SB of looking for, need to use all measurement GAP.Be this time, the priority that the BSIC of GSM adjacent area confirms is the highest, and other priority that need to use GAP to measure are temporarily lowerd.In prior art, under the 40ms/80ms GAP cycle, complete the needed GAP number of cycles of the initial confirmation of BSIC as shown in following table three:
Table three
For the measurement of GSM adjacent area, there is following several shortcoming in prior art:
1) under LTE business state, not only need to use GAP to carry out BSIC confirmation, also need in measuring report cycle, carry out rssi measurement, measure each GSM adjacent area frequency in report cycle for one and will adopt 3 sampling points.Thus, carry out GSM adjacent area when synchronous receiving the blind SB of looking for of data with continuous GAP, cannot guarantee to measure sampled point number and uniformity thereof to rssi measurement in report cycle.
2) GSM carries out BSIC while heavily confirming (ReBSIC) in each adjacent area on synchronously, also need to use GAP, use a continuous N GAP to receive when data are blind looks for SB, the BSIC that middle any one GAP inserts other frequencies heavily confirms, all will cause the incomplete of this blind SB of looking for search.
3) GSM adjacent area synchronous (BSIC initially confirms) adopts the mode of the blind SB of looking for, and this mode algorithm there are certain requirements frequency deviation, if when GSM adjacent area frequency deviation is very large, will cause effectively detecting SB.

The first adjacent area synchronization module 21, carries out BSIC and initially confirms in order to utilize wherein one group or many groups to measure GAP;
The second adjacent area synchronization module 22, carries out BSIC and heavily confirms or rssi measurement in order to utilize remaining one group or many groups to measure GAP.
First, for the convenience of present specification narration, do following agreement/definition:
1) if no special instructions, following method, device is applicable to LTE and TD-SCDMA system/business state simultaneously, wherein, for LTE system if no special instructions, comprises/be applicable to simultaneously two kinds of systems of LTE-TDD and LTE-FDD;
2) 40ms GAP refers to take in LTE system the GAP of 40ms as cycle duration 6ms; 80ms GAP refers to take the GAP of 80ms as cycle duration 6ms;
3) establish Δ=5/13ms, GSM frame length=12 Δ=60/13ms so, 5ms=13 Δ, 40ms=104 Δ;
4) FN refers to the actual frame number of GSM, and fn refers to the result of the actual frame number mould 51 of GSM: fn=(FN) %51, during without special instruction, GSM frame number refers to fn herein.
Concrete, the side-play amount between described measurement GAP and GSM frame comprises: the first side-play amount, the second side-play amount and the 3rd side-play amount, wherein differ between 8 Δs, the 3rd side-play amount and the first side-play amount and differ 4 Δs between the second side-play amount and the first side-play amount.
With 40ms GAP and GSM and the initial frame head of LTE, be aligned to example, use continuously 9 positions of time slot long data in GSM frame of 40ms GAP reception GSM as shown in Figure 8, wherein, the duration of measuring GAP is 6ms, the duration of GSM frame is 4.615ms, therefore, measure the 9 time slot long datas (i.e. the data of 9 slot lengths) that GAP can receive GSM for one.
As shown in Figure 8,40ms GAP receives " 0 ", " 8 ", " 17 ", " 26 " in the long GSM data of 9 time slots continuously ... it is the result of the actual frame number FN of GSM mould 51, GSM frame number is as the criterion to receive data original position place GSM frame number, in Fig. 8, " 8 " represent that receiving position is to start in the frame head 2/3 frame length position apart from the 8th frame, last till apart from the frame head 19/24 frame length position of the 9th frame and finish, wherein 19/24=2/3+1/8.
At this, with 40ms GAP and GSM and the initial frame head of LTE, be aligned to example, can obtain the first side-play amount is that 0, the second side-play amount is that 8 Δs (also differing 8 Δs between the second side-play amount and the first side-play amount), the 3rd side-play amount are 4 Δs (also differing 4 Δs between the 3rd side-play amount and the first side-play amount).In addition, if the initial frame head aligned relationship of GSM and LTE is other situations, for example LTE frame and GSM frame deviation 2 Δs, the first side-play amount is 2 Δs, the offset relationship between same satisfied and the first side-play amount of the second side-play amount and the 3rd side-play amount simultaneously: differ between the second side-play amount and the first side-play amount between 8 Δs, the 3rd side-play amount and the first side-play amount and differ 4 Δs, now, the second side-play amount is that 10 Δs, the 3rd side-play amount are 6 Δs.
Concrete, if the actual frame number of GSM and the poor N of hypothesis frame number, frame header deviation differs into delata, so
1) fn+n=(FN+N) %51, and fn+n<51;
2) the frame bias internal value of reception data is Offset+delata, wherein Offset+delat<60/13=12 Δ.
According to the side-play amount between the measurement GAP shown in Fig. 8 and GSM frame, just a plurality of measurement GAP can be divided into many groups.In the present embodiment, measurement GAP is divided into 6 groups, every group of corresponding GSM frame number is continuous, specifically please refer to following table four:
Table four
In table four, schematically list 66 and measured GAP, measure GAP arranged in sequence for these 66, sequence number is " 1. ", " 2. ", " 3. " ... according to the side-play amount of measuring between GAP and GSM frame, by these 66, measure GAP and be divided into 6 groups, every group is 11 and measures GAP, and it is continuous in logic that every group 11 measure the GSM frame that GAP are corresponding, " fn " frame number is continuous, namely continuous after actual frame number FN mould 51.
Because each measures 9 time slots that GAP receives GSM, just can guarantee that continuous twice reception in front and back of " fn " frame number is end to end.Concrete, please refer to Fig. 9, it is that one group of 40ms GAP realizes the continuous data receiver schematic diagram of GSM frame number.Wherein, in Fig. 9, exemplary first three that shows in the grouping shown in table four first group measured the situation that GAP receives GSM data.At this, as long as the GSM adjacent area of this frequency exists really, in 11 such reception data (utilize 11 and measure the data that GAP receives), must find complete FCB(in the present embodiment by first searching FCB so, then according to FCB, obtain the method for SB, therefore first-selection need be obtained FCB, to this, will be explained below; In other embodiments of the invention, also can directly search SB).In fact, if the SB position of all GSM adjacent areas does not overlap, measure the ReBSIC demand that GAP also can meet all adjacent areas for 11.
In the present embodiment, measurement GAP is divided into six groups, wherein, two groups of side-play amounts of measuring between GAP and GSM frame are the first side-play amount; Two groups of side-play amounts of measuring between GAP and GSM frame are the second side-play amount; Two groups of side-play amounts of measuring between GAP and GSM frame are the 3rd side-play amount.In other embodiments of the invention, also 40ms GAP can be divided into three groups, wherein, one group of side-play amount of measuring between GAP and GSM frame is the first side-play amount; One group of side-play amount of measuring between GAP and GSM frame is the second side-play amount; One group of side-play amount of measuring between GAP and GSM frame is the 3rd side-play amount.For table four, the 1st group and the 4th is combined into one group, and the 2nd group and the 5th is combined into one group, and the 3rd group and the 6th is combined into one group.
At this, at length narrated the grouping situation for 40ms GAP, similarly, also can obtain the grouping situation of 80msGAP.Concrete, please refer to following table five:
Table five
At this, schematically show 33 and measure GAP, measure GAP arranged in sequence for these 33, sequence number is " 1. ", " 2. ", " 3. " ... according to the side-play amount of measuring between GAP and GSM frame, by these 66, measure GAP and be divided into 3 groups, every group is 11 and measures GAP, and it is continuous in logic that every group 11 measure the GSM frame that GAP are corresponding, " fn " frame number is continuous, namely continuous after actual frame number FN mould 51.
After having completed the grouping of measurement GAP, then, by utilizing wherein (in a plurality of measurement GAP groups after grouping) a group or many group measurement GAP to carry out BSIC, initially confirm; Utilizing remaining one group or a plurality of measurement GAP to carry out BSIC heavily confirms or rssi measurement.
In the present embodiment, for the initial confirmation of BSIC (for SB blind check), by the detection for FCB, be achieved.Because FCB is stronger for the tolerance ability of frequency deviation, therefore, first by measuring GAP, carry out FCB synchronous (being blind check FCB), after FCB is synchronous, according to the FCB after synchronous, receive SB, realize BSIC and initially confirm.Visible according to the 51 multi-frame structure schematic diagrames of the GSM shown in Fig. 2 and table four, table five, at the FN of GSM frame, find after FCB, the same position of FN+1 frame must be just SB so, so FCB finds, looks for SB again, for 40ms GAP and 80ms GAP, all needs to add time 240ms again.For example, first in the 1st group measured blind check in GAP and arrived FCB, for 40ms GAP and 80ms GAP, all need in second measurement GAP in this group, obtain SB, needs respectively to measure GAP and 3 measurement GAP through 6, is 240ms.
According to the grouping of table four and table five, in the present embodiment, schematically provided the search strategy (namely for the mode of choosing of measuring GAP group) of several FCB as shown in following table six:
Table six
Wherein, FCB search strategy 40_GAP_SINGLE refers to adopt two groups to measure GAP, respectively the 1st group in corresponding table four and the 4th group are (owing in table four, measurement GAP being divided into six groups, therefore 3k correspondence two groups), now, for the GAP number of the blind FCB of looking for, be 11, and the lasting maximum duration of the blind FCB of looking for is 31 measurement GAP numbers, under this FCB search strategy, InitBSIC maximum duration is 1445.192ms, specifically by 30*40+9* (60/13)/8=1445.192ms, is obtained.Now other 20 measurement GAP can be used for ReBSIC or rssi measurement, and the measurement GAP that remains four groups (the 2nd group, the 3rd group, the 5th groups and the 6th group) can be used for ReBSIC or rssi measurement.
FCB search strategy 40_GAP_TRI refers to adopt one group and measures blind the looking for of FCB that GAP realizes a frequency, can adopt respectively the 1st group, the 3rd group or the 5th group in table four, for blind the looking for of FCB of a frequency, GAP number for the blind FCB of looking for is 11, and the lasting maximum duration of the blind FCB of looking for is 61 measurement GAP numbers, InitBSIC maximum duration is 2645.192ms.Same, BSIC initially confirms that one group/many group measurement GAP that (namely FCB is blind looks for) does not use can be used for ReBSIC or rssi measurement.
For this search strategy 40_GAP_TRI, also can adopt three groups to measure blind the looking for of FCB that GAP does respectively three frequencies, now the required InitBSIC maximum duration of each frequency is (2645.192+5*40)/3=948.397ms simultaneously.
FCB search strategy 40_GAP_ENH refers to adopt four groups to measure GAP, distinguish the 1st group, the 3rd group, the 4th group and the 6th group in corresponding table four, now, GAP number for the blind FCB of looking for is 17, and the lasting maximum duration of the blind FCB of looking for is 25 measurement GAP numbers, under this FCB search strategy, InitBSIC maximum duration is 1205.192ms.Same, BSIC initially confirms that one group/many group measurement GAP that (namely FCB is blind looks for) does not use can be used for ReBSIC or rssi measurement.

After having confirmed the search strategy of FCB, chosen for after carrying out the measurement GAP group of FCB/SB, just can utilize remaining one group or many groups to measure GAP and carry out BSIC and heavily confirm or rssi measurement.For BSIC, heavily confirm, definite according to the time shown in table one and table two, only need meet under this time and be ReBSIC, formed selection mode is varied thus, and the application no longer exemplifies.
And for rssi measurement, select in remaining set, do not need the measurement GAP that is ReBSIC to carry out.Preferably, the measurement for RSSI is evenly distributed in measurement report cycle.At this, simply lift an example and be explained, suppose that the search strategy of FCB is selected 40_GAP_SINGLE, measurement report cycle is 480ms, hypothesis does not need to be ReBSIC simultaneously, now for the measurement of RSSI is evenly distributed in, measures in report cycle, can select sequence number be " 2. ", " 9. ",
measurement GAP do rssi measurement.At this, in the measurement report cycle of 480ms, remove 8 measurement GAP that will carry out FCB search, in remaining 16 are measured GAP, on average choose, can realize the measurement of RSSI is evenly distributed in measurement report cycle.In addition, if now according to the time requirement of ReBSIC, need to take one of them or a plurality of measurement GAP is ReBSIC, in remaining measurement GAP, on average choose, to carry out rssi measurement.
In order to further illustrate the application's content, the subsequent data receiver to measurement GAP illustrates.Please refer to Figure 10, the data receiver task configuration flow schematic diagram of the measurement GAP that it is the embodiment of the present invention.As shown in figure 10, to measuring the data receiver task configuration of GAP, mainly comprise the steps:
Execution step SA1, starts;
Then perform step SA2, get initBSIC queue, check and need the frequency of initBSIC number, the content aware that this point can issue according to network, the application repeats no more this;
Then perform step SA3, judge whether the frequency number of initBSIC is greater than 0, if NO, that is to say the frequency number that does not need to carry out initBSIC, forward step SA19 to, to judge whether carrying out ReBSIC; If yes, perform step SA4, calculate numbering and the corresponding Route value thereof of current GAP, at this, mainly according to current network clocking information, draw table four/table five;
Then perform step SA5, according to GAP numbering and current FCB search strategy, check whether current GAP belongs to FCB search and use, wherein, about the selected of FCB search strategy, can be chosen according to description above, after FCB search strategy is selected, perform step SA6, judge whether current GAP belongs to that search FCB uses; If NO, forward equally step SA19 to; If yes, perform step SA7, from initBSIC queue, get frequency, check that this frequency is which time GAP receives, to this, mainly based on different frequent points, adopt not measurement GAP on the same group to carry out FCB and search plain consideration;
Then perform step SA8, if measure GAP and carry out FCB search for the 1st time, perform step SA9, this frequency is recorded the Route value of current GAP and is carried out the Route value of FCB search as it, being about to the selected measurement GAP group as this frequency FCB search records, the measurement GAP that belongs to this group so that follow-up is all used as the initBSIC of this frequency, after having recorded, then perform step SA10 and SA11, from GAP constant offset position, start to configure the long FCB blind check data receiver task of 9 GSM time slots, utilize and measure GAP reception GSM frame data to realize the blind check for FCB, and the discontinuous GAP count pick up value of this frequency adds 1, at same group, to measure in GAP, the numbering of measuring GAP moves down one,
If not measure GAP for the 1st time, carry out FCB search, perform step SA12, check whether the Route value of current GAP mates with frequency GAP last time reception Route value, check whether to belong to and started a certain group of FCB search, then perform step SA13, if do not mate, perform step SA19; If coupling, perform step SA14, on whether the last time GAP that checks the FCB of frequency receives synchronously, if on not synchronous, perform step SA17, judged whether (confirming blind whether unsuccessfully the looking for of FCB of continuous 11 times) the 12nd time, perform step if not SA10 and SA11(and continue FCB blind check), if performing step SA18 rejects this frequency from InitBSIC queue and (makes way for other frequencies and do blind check, if this frequency signal is very strong, after next RSSI sequence, (take the flow process shown in Figure 11 as example) can reenter InitBSIC queue); If synchronously go up, perform step SA16, according to FCB synchronizing information, calculate the SB receiving position of current GAP, configuration SB receives task;
At this, mainly for the situation that often has the GSM adjacent area of a plurality of frequencies in reality, therefore, when utilizing different measurement GAP groups to carry out FCB blind check, need to record simultaneously each measure GAP group for frequency, to prevent that interspersed between different frequent points from causing the incomplete of the blind SB of looking for search, improved the reliability of GSM nearby region measurement thus.
After execution step SA16, then perform step SA19, the frequency of searching loop ReBSIC queue, checks the timing information of each frequency; If find that the residue empty position of current GAP can configure the SB reception of certain frequency, configure reception task, and from ReBSIC queue, frequency is rejected, at this, mainly judge whether to carry out ReBSIC;
Then perform step SA20, the adjacent area frequency RSSI that the residue empty position configuration of current GAP does not also complete epicycle receives, and judges whether to carry out rssi measurement;
After having carried out above-mentioned part/Overall Steps, for an operation of measuring GAP, completed, for this measurement GAP, can perform step SA21 and finish.
