Description

A kind of measurement cell determining method and device

Technical field

The present invention relates to communication technical field, particularly a kind of measurement cell determining method and device.

Background technology

Development along with the communication technology, detect arriving time difference (OTDOA, Observed Time Difference Of Arrival) localization method is a kind of enhancement type district ID(E-Cell ID of 3GPP organization prescribed) the standardization location solution of localization method.

Wherein, OTDOA is the technology positioning according to the time difference of signal transmission between evolution base station (eNB, Evolved Node B) and subscriber equipment (UE, User Equipment).As shown in Figure 1, Fig. 1 is the schematic diagram of OTDOA positioning principle in prior art.In Fig. 1, eNB1(is with reference to eNB) by location reference signals (PRS, Positioning Reference Signal) add in down link signal to be sent, (minimum period is 160ms periodically to send PRS signal, maximum cycle is 1280ms), eNB1 sends the PRS signal of several continuous descending sub frames in each cycle, is called a PRS occasion.UE carries out related calculation to a plurality of descending PRS signal receiving, and calculates each neighbours eNB(such as eNB2 and eNB3) with the difference of time of advent of the PRS signal of eNB1, UE observes to network equipment report the measured value that arrives the time difference.Network equipment determines that according to the measured value of the PRS signal arrival time difference value of eNB2 and eNB1 UE take on the hyperbola A that eNB1 is focus, specifically as shown in Figure 1; According to the measured value of the PRS signal arrival time difference value of eNB3 and eNB1, determine that UE take on the hyperbola B that eNB1 is focus, like this, the intersection point of A and B is exactly the position of UE.

In the prior art, OTDOA localization method requires to measure the poor (RSTD time of advent of a plurality of communities and reference cell, Reference signal time difference), 3GPP requires UE, and approximately 16 PRS cycles, (PRS cycle minimum is 160ms, be 1280ms to the maximum) the interior community that can measure maximum 3 frequency layer, each frequency layer at least will be measured 16Ge community.Because UE measurement capability is limited, the time that all communities of a PRS occasion of measurement may need is longer, has likely surpassed the PRS cycle, thereby has missed a PRS occasion.On the other hand, even if UE measures the time of a PRS occasion and is no more than a PRS occasion, but when measuring the RSTD of a plurality of frequencies, UE may also not complete the measurement of the PRS occasion of this frequency before the PRS of next frequency occasion starts; And, owing to mourning in silence (muting) in community in certain PRS occasion, dispatch this community and cannot obtain measurement result at the PRS of muting occasion.

Therefore, how effectively determining and to measure community, and rationally utilize UE to measure resource and PRS occasion resource, meet the measurement requirement of 3GPP, is to measure OTDOA to have problem to be solved.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out to clear, complete description, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

In this application example, UE is before carrying out each OTDOA measurement, by the measuring state of each community, the measurement number of times of community, the maximum of each community measure the measurement priority of number of times, community and community the next location reference signals time interval (PRS occasion) whether mourn in silence (muting) determine the frequency measured at upper once PRS occasion and the community of measurement.

Before introducing this embodiment of the present invention, first do following parameter setting:

1,, for a measuring state is given in each community, described measuring state can comprise following three kinds but be not limited to this:

Failed: show that this community is not measured or not successfully measurement;

Bad: represent that this community measures, but measurement result is not so good community;

Success: show the successfully measurement of this community;

Generally, the initial measured state of each community is Failed.

2, be each cell allocation cell measurement number of times (Measure Num), for recording cell, be repeated to carry out the number of times that TOA measures, initial measurement number of times (Measure Num) is 0, i.e. Measure Num=0.

3, be the maximum number of times Max Num Repeat Measur that measures of other cell settings except RSTD reference cell, the maximum number of times of measuring is set according to UE RSTD measurement capability, and UE RSTD measurement capability is strong, and Max Num Repeat Measur value is larger; UE RSTD measurement capability is strong, and Max Num Repeat Measur value is less.Generally measuring number of times maximum can be 4, certainly, is not limited to this, can also be according to carrying out adaptability revision under actual conditions, and such as being revised as 5 or 7 or 10 etc.

4, by community to be measured according to frequency categorization; Set the measurement priority of each community, measure the order of the high-rise sending measuring of the set basis community of priority and set, preceding native region priority is high, after native region priority low.

Refer to Fig. 2, a kind of flow chart of measuring cell determining method that Fig. 2 provides for the embodiment of the present invention; Described method comprises:

Step 201: determine Candidate Frequency list to be measured; Described Candidate Frequency list comprises at least one Candidate Frequency;

In this step, the measurement that subscriber equipment sends according to network equipment asks to determine Candidate Frequency list to be measured.A kind of process of definite Candidate Frequency list to be measured comprises:

First, user equipment (UE) receives the OTDOA measurement message that network equipment sends, described OTDOA measures in message and can comprise: the measuring frequency that needs are measured, the measurement cell i d under each measuring frequency, the temporal information (or time location information) of measuring the location reference signals time interval (PRS occasion) of community, measurement community muting information etc.

Then, the measurement microzonation that UE measures described OTDOA in message according to frequency is divided into measurement cell list, and records each cell id of measuring community, measurement number of times and measuring state;

Then, UE judges that the common frequency measurement cell list that whether has non-NULL in described measurement cell list (can comprise one or more measurements community in this measurement cell list, also can comprise zero measurement community), if existed, using a Candidate Frequency to be measured in Candidate Frequency list to be measured with frequent rate; If there is no, finish this flow process;

Then, UE continues to judge the different-frequency measure cell list that whether has non-NULL in described measurement cell list, if existed, from described measurement cell list, selects the alien frequencies frequency of a non-NULL; Calculate the time location of the PRS occasion of described alien frequencies frequency; Afterwards, judge whether the time location of the PRS occasion of described alien frequencies frequency mates with measurement clearance gap, if so, determine that described alien frequencies frequency is Candidate Frequency to be measured; Otherwise, determine that described alien frequencies frequency is for can not survey alien frequencies frequency;

Wherein, whether the time location that judges PRS occasion mates with measurement clearance gap, can determine by the time location of PRS occasion and the situation that overlaps of gap, generally, PRS occasion and gap include six subframes, such as, in the larger situation of bandwidth ratio, the two has at least a subframe to overlap in time, in the situation that bandwidth is smaller, may need several subframes to overlap in time, specifically depend on the circumstances, can be that 2 subframes overlap in time, can be also that 3 or 4 subframes overlap etc. in time.

Afterwards, if also have other non-NULL alien frequencies in described measurement cell list, re-execute the step of the alien frequencies frequency of an alien frequencies community to be measured of described selection, from described measurement cell list, select the alien frequencies frequency of next alien frequencies community to be measured, calculate the time location of the PRS occasion of described alien frequencies frequency, whether the time location that judges described PRS occasion mates with measurement clearance gap, if so, determines that described alien frequencies frequency is Candidate Frequency to be measured; Otherwise, determine that described alien frequencies frequency is for can not survey alien frequencies frequency.Until the frequent rate computing of the alien frequencies community to be measured of the non-NULL in described cell list to be measured is complete.

Optionally, after alien frequencies frequency in described measurement cell list is all finished dealing with, whether UE judges whether to have sent to network equipment the gap request of alien frequencies frequency, do not have to survey alien frequencies frequency, wherein, described gap request comprises the needed gap of all alien frequencies frequencies; If all no, the measurement prs that calculates the location reference signals of each alien frequencies frequency is offset meas prs offset; To network equipment, send each alien frequencies frequency and corresponding meas prs offset.

That is to say, UE can first judge whether to have sent gap request to network equipment, if sent described gap request, finishes this flow process; If do not send described gap request, judged whether immeasurability alien frequencies; If had, calculate the measurement prs skew meas prs offset of the location reference signals of each alien frequencies frequency; To network equipment, send each alien frequencies frequency and corresponding meas prs offset; Otherwise, finish this flow process.

Certainly, UE also can first judge whether immeasurability alien frequencies, if there is no immeasurability alien frequencies, finishes this flow process; If had, can measure alien frequencies, judge whether to have sent gap request to network equipment; If no, calculate the measurement prs skew meas prs offset of the location reference signals of each alien frequencies frequency; To network equipment, send each alien frequencies frequency and corresponding meas prs offset; Otherwise, finish this flow process.

Wherein, the process of described definite Candidate Frequency list to be measured specifically as shown in Figure 4, is not described in detail at this.

Step 202: the time location that calculates the time interval PRS of the location reference signals next time occasion that in described Candidate Frequency list, each Candidate Frequency starts from current time;

In the present embodiment, calculate the first time location with frequency PRS occasion, then according to the described first time location with frequency PRSoccasion, calculate the time location of the next PRS occasion of each Candidate Frequency from current time.

Step 203: the nearest PRS occasion of chosen distance current time from the time location of the occasion of PRS next time of described each Candidate Frequency, using described apart from the nearest corresponding frequency of PRS occasion of current time as treating measured frequency;

That is to say, the time location of the occasion of PRS next time of several Candidate Frequencies is compared, select wherein the PRS occasion corresponding frequency nearest with current time as treating measured frequency.

Step 204: treat the community to be measured under measured frequency described in determining.

Wherein, first described in judgement, treat under measured frequency, whether have community to be measured, that is to say, described in treat can comprise the community to be measured that this need to be measured under measured frequency, also can comprise zero community to be measured, do not need the community to be measured of measuring.

Wherein, if described in treat to comprise under measured frequency the community to be measured that this need to be measured, a kind ofly treat that the process of the community to be measured under measured frequency is described in determining:

First, first described in judgement, treat whether measured frequency is with frequent rate, if with frequent rate, described in judgement, treat that reference cell under measured frequency treats on measured frequency that described once whether PRS occasion is in silent status, if in non-silent status, using described, treat that reference cell under measured frequency is as community to be measured, and according to other height of native region priority, select successively Cell-1 measurement result of Max Measur for not measuring successfully from the described cell list for the treatment of measured frequency, do not surpass the maximum of setting and measure number of times, and treat on measured frequency that described once the community of PRS occasion in non-silent status is as community to be measured,

Such as, if UE is according to the performance of self, multipotency is to 8 cell measurements at every turn, if the reference cell under same frequent rate to be measured is as community to be measured, also need in the cell list from this same frequent rate to be measured, select 7 communities as community to be measured, its selection mode can be according to the measurement result of selecting successively from high to low community of the priority of each community for measuring successfully, surpass the maximum measurement number of times of setting, and on it once the community of PRS occasion in non-silent status as community to be measured.

If frequency to be measured is that alien frequencies or described reference cell are in silent status, from described treat in the cell list measured frequency, according to other height of native region priority, select successively Cell measurement result of Max Measur for measuring successfully, over the maximum measurement number of times of setting, and treat on measured frequency that described once the community of PRS occasion in non-silent status is as community to be measured;

Wherein, Max Measur Cell is for measuring the maximum number of community.

Wherein, the described flow chart for the treatment of the cell list to be measured under measured frequency described in determining as shown in Figure 5, does not repeat them here.

In the embodiment of the present invention, first determine Candidate Frequency list to be measured, then select the nearest corresponding frequency of PRS occasion of the time location middle distance current time of the occasion of PRS next time of Candidate Frequency in Candidate Frequency list as treating measured frequency, and treat the community to be measured under measured frequency described in determining, be in the embodiment of the present invention, reasonably to select frequency and the community of measurement next time, thereby effectively avoided because missing PRS occasion next time, and the technical problem that the certainty of measurement causing declines; Also effectively avoid the waste because of same community measurement resource, time and power that repeatedly invalid duplicate measurements causes, thereby improved the efficiency of measuring.

Also refer to Fig. 3, the another kind that Fig. 3 provides for the embodiment of the present invention is measured the flow chart of cell determining method, and described method comprises:

Step 300: determine Candidate Frequency list to be measured;

In this step, the OTDOA that subscriber equipment sends according to network equipment measures message and determines Candidate Frequency list to be measured.Its process of determining Candidate Frequency list to be measured refers to Fig. 4, does not repeat them here.

Step 301:UE judges whether described Candidate Frequency list to be measured is empty (whether comprising Candidate Frequency to be measured), if not, and execution step 303; If so, execution step 302: finish this flow process;

Step 303:UE calculates the time location of the time interval PRS of the location reference signals next time occasion that in described Candidate Frequency list to be measured, each Candidate Frequency starts from current time;

Its computational process refers to above-mentioned, does not repeat them here.

Step 304:UE selects the nearest corresponding frequency of PRS occasion of the time location middle distance current time of the occasion of PRS next time of described Candidate Frequency as treating measured frequency;

Described in determining, treats step 305:UE under measured frequency, whether have community to be measured; If existed, execution step 306; Otherwise, execution step 308;

Generally, treat under measured frequency, there are a plurality of communities for one.UE need to judge in a plurality of communities under it, which community is this community that need to measure, i.e. community to be measured.Which community is not need this measurement.Whether its definite mode can surpass the maximum of setting according to the measurement number of times of community and measure number of times, and whether measuring state for successfully or failure, or measurement result is bad etc., and condition is determined.

Wherein, in the community to be measured of determining, can be to exist this to treat to need under measured frequency one or more communities of measuring, certainly, described in treat also can not need under measured frequency the community measured, there is not community to be measured.

Described in its UE determines, treat the flow chart of the community to be measured under measured frequency as shown in Figure 5, do not repeat them here.

Step 306: treat the community to be measured under measured frequency described in determining;

Wherein definite process refers to above-mentioned.

Step 307: the described measurement community of determining is measured;

After measurement completes, finish this flow process.

The measuring process of Qi Dui community has been to know technology, does not repeat them here.

Step 308: described in renewal, treat measured frequency the occasion of PRS next time time location for this treat measured frequency under the time location of PRS occasion next time; Then return to step 304, proceed to treat the selection of measured frequency.

In the embodiment of the present invention, by further, judge in cell list to be measured, whether there is community to be measured, while there is community to be measured for this cell list to be measured, directly this community to be measured is measured, when not there is not community to be measured, upgrade this community to be measured the occasion of PRS next time time location for this treat measured frequency under the time location of PRS occasion next time, thereby improved measurement community efficiency.

Also refer to Fig. 4, Fig. 4 determines in Fig. 3 in this embodiment, to be measured as first example, to comprise the flow chart of Candidate Frequency list to be measured:

Step 401:UE receives the OTDOA measurement message that network equipment sends;

That is to say, UE receives the pattern that network equipment sends at Prs occasion, and as shown in Figure 6, Fig. 6 is the schematic diagram of a kind of pattern of the Prs occasion that in the embodiment of the present invention, subscriber equipment receives network equipment transmission to this pattern;

As shown in Figure 6, the time 0 is the time that starts to select Candidate Frequency.

Suppose that f1 is for frequently same, the community that will measure in frequency f 1 is with community C01, and C02 is example;

Suppose that f2 is alien frequencies, the community that will measure in frequency f 2 is with community C11, and C12 is example;

The measurement microzonation that step 402:UE measures described OTDOA in message according to frequency is divided into measurement cell list, and records each cell id of measuring community, measurement number of times and measuring state;

Wherein, described cell list to be measured is as shown in table 1, comprises common frequency measurement cell list and different-frequency measure cell list, and wherein, common frequency measurement cell list and different-frequency measure cell list comprise respectively frequency, cell id, measurement number of times and measuring state.

Table 1

Step 403:UE judges whether the common frequency measurement cell list in described cell list to be measured is empty, if so, and execution step 404; Finish this flow process; Otherwise, execution step 405;

In this embodiment, UE finds to have the measurement community that needs measurement in common frequency measurement cell list, and common frequency measurement cell list is non-NULL; Otherwise, in common frequency measurement cell list, there is not the measurement community that needs measurement, common frequency measurement cell list is empty.

In this embodiment, find will survey with frequency (f1) You Liangge community.From the measurement number of times of table 1, being measured as first of Dui Liangge community measured.

Step 405:UE will elect Candidate Frequency to be measured as with frequency f1; Be chosen as one of Candidate Frequency to be measured;

Step 406:UE judges the different-frequency measure cell list that whether has non-NULL in described measurement cell list, if so, and execution step 407; Otherwise, execution step 408: finish this flow process;

In this embodiment, UE finds to exist the alien frequencies f2 of non-NULL, and alien frequencies f2 Xia Youliangge community will be surveyed.

Step 407:UE selects the alien frequencies frequency of a non-NULL from described measurement cell list;

Select alien frequencies f2.

Step 409:UE calculates the time location of the PRS occasion of alien frequencies frequency;

In this embodiment, as shown in Figure 6, the time location of the PRS occasion2 of the alien frequencies of UE calculating f2 is 15 to 21.In Fig. 6, the solid line boxes of label 1 correspondence, represents Prs occasion1; The solid line boxes of label 2 correspondences represents Prs occasion2; That dashed rectangle is corresponding is measurement clearance gap.

Step 410:UE judges whether the time location of PRS occasion mates with measurement clearance gap; If so, execution step 411; Otherwise, execution step 412;

In this step, in the larger situation of bandwidth ratio, if UE finds that the beginning of gap, to the time finishing, as long as there is a subframe to overlap with the time location of PRS occasion, can be just Candidate Frequency to be measured by alien frequencies frequency; Otherwise, determine that described alien frequencies frequency is for can not survey alien frequencies frequency.

Certainly, in the smaller situation of bandwidth, may at least need several subframes to overlap in time, could determine that alien frequencies frequency is Candidate Frequency to be measured.Concrete subframe need to depend on the circumstances.In this embodiment, the position of gap, 8 to 14, because the time location with PRS occasion2 overlaps with gap, so the time location of PRS occasion2 does not mate with gap, performs step 412.

Step 411: determine that described alien frequencies is Candidate Frequency to be measured; Execution step 413;

Step 412: determine that described alien frequencies is for can not survey alien frequencies frequency; Execution step 413;

Determine that f2 is for can not survey alien frequencies frequency.In this embodiment, f2 is defined as can not survey alien frequencies frequency.

Step 413:UE judges whether to handle all alien frequencies in described measurement cell list, if so, and execution step 414; Otherwise, return to step 407;

In this embodiment, owing to only having an alien frequencies f2 in cell list to be measured, so all process and be over, certainly, in other embodiments, if there are a plurality of alien frequencies, need to continue to carry out the step of above-mentioned steps 407 to 414, until handle described alien frequencies.

Step 414:UE judges whether to have sent gap request to network equipment, judges whether not have to survey alien frequencies, if all, and execution step 415: finish this flow process; If all no, execution step 416;

Wherein, in this embodiment, UE can first judge whether to have sent gap request to network equipment, if sent described gap request, finishes this flow process; If do not send described gap request, judged whether immeasurability alien frequencies; If had, perform step 416; Otherwise, finish this flow process.

Certainly, UE also can first judge whether immeasurability alien frequencies, if there is no immeasurability alien frequencies, finishes this flow process; If had, can measure alien frequencies, judge whether to have sent gap request to network equipment; If no, perform step 416; Otherwise, finish this flow process.

In this step, gap request comprises the gap of all alien frequencies needs, comprises the alien frequencies as Candidate Frequency, and immesurable alien frequencies.In this embodiment, because f2 is can not measured frequency, so execution step 416.

Step 416:UE calculates the measurement prs skew (meas prs offset) of the location reference signals of each alien frequencies;

In this embodiment, owing to only having an alien frequencies f2, so it is certain only to have calculated the meas prs offset of alien frequencies f2, if a plurality of alien frequencies needs all to calculate the meas prs offset of each alien frequencies.

Step 417:UE reports each alien frequencies frequency and corresponding measurement prs skew (meas prs offset) to network equipment.

In this embodiment, reported the meas prs offset of f2 and f2.

In embodiment described in above-mentioned Fig. 4, each community is to be measured as first example, illustrate below, in each community, there is non-situation about measuring first, suppose another pattern of the Prs occasion that UE reception network equipment sends as described in Figure 7, Fig. 7 is the schematic diagram that the Prs occasion of subscriber equipment reception network equipment transmission in the embodiment of the present invention sends another kind of pattern.In Fig. 7, the solid line boxes of label 1 correspondence, represents Prs occasion1; The solid line boxes of label 2 correspondences represents Prs occasion2; That dashed rectangle is corresponding is measurement clearance gap.

From this Fig. 7, the time 10 is the time that starts to select Candidate Frequency.

Suppose that f1 is for frequently same, the community that will measure in frequency f 1 is with community C00, and C01 is example;

Suppose that f2 is alien frequencies, the community that will measure in frequency f 2 is with community C10, and C11 is example;

Afterwards, the measurement microzonation of described OTDOA being measured in message according to frequency is divided into measurement cell list, and record each cell id of measuring community, measure number of times and measuring state, wherein, described measurement cell list is as shown in table 2, comprises common frequency measurement cell list and different-frequency measure cell list;

Table 2

Again, UE judges the common frequency measurement cell list that whether has non-NULL in this measurement cell list;

In this embodiment, discovery co-frequency cell C00 measures and does not successfully need to survey again, and C01 measures number of times and reaches the maximum number of times of measuring, and does not also need to measure, and therefore, common frequency measurement cell list is sky.

Again, then judging in this measurement cell list whether have non-NULL different-frequency measure cell list, find to exist alien frequencies f2You Liangge community to survey, is not empty.

Again, select the alien frequencies frequency of a non-NULL from described measurement cell list, selected alien frequencies frequency f 2 in the present embodiment, its process is identical with the process of above-mentioned Fig. 4, specifically refers to above-mentionedly, does not repeat them here.

Again, determine that alien frequencies frequency f 2, for Candidate Frequency, just performs step 413, judge that whether all alien frequencies are all processed, if handled, its follow-up step is identical with in above-mentioned steps, specifically refers to above-mentionedly, does not repeat them here.

In the embodiment of the present invention, owing to having limited the maximum of each community, measure number of times, and no longer duplicate measurements after cell measurement success, can effectively avoid the insignificant duplicate measurements in Yi Ge community, thereby effectively avoid the waste of time and power.Due to according to the each community number of measuring of measurement capability restriction of UE, effectively avoid missing PRS occasion.

Also refer to Fig. 5, for what provide in Fig. 3, a kind ofly treat a kind of flow chart that measured frequency Xia community is community to be measured described in determining, in this embodiment, UE receives pattern that network equipment sends Prs as shown in Figure 8, and Fig. 8 receives the schematic diagram that network equipment sends the pattern of Prs for a kind of UE providing in the embodiment of the present invention.As shown in Figure 8: in prs occasion1, community C00 and C01 send out prs; In prs occasion2, community C10 and C11 send out prs; In prs occasion3, only have community C00 to send out prs; In prs occasion4, only have community C10 to send out prs; In prs occasion5, only have community C01 to send out prs;
