Shown in Figure 1, the embodiment of the present invention provides a kind of room subsystem localization method schematic flow sheet, and implementation method comprises particularly:
Step S101, according to the end message monitored that each radio frequency remote unit RRU received reports, has judged whether that at least two RRU monitor target terminal.
Step S102, if there are at least two RRU to monitor target terminal, the RRU once accessed before determining described target terminal.
Step S103, from all RRU monitoring target terminal, determines the RRU with the locus intercommunication of the front RRU once accessed.
Step S104, selects a RRU from the RRU of the intercommunication determined, and using the position of the 2nd RRU of RRU selected as the current position of described target terminal.
Wherein, the space in space and the 2nd RRU place that the RRU of so-called locus intercommunication refers to a RRU place is geographically interconnected, and namely terminal can move to the 2nd RRU from a RRU.
Under this special application scenarios of room subsystem, a usual community covers by multiple RRU is collaborative to promote MPS process area, and the signal between multiple RRU is by returning to baseband processing unit (BuildingBasebandUnit after superposition, BBU) demodulation, in light of this situation, terminal in the subsystem of room can constantly to RRU reporting information, and then RRU collects the reporting information of terminal, can report the end message monitored every a SRS cycle to BBU.According to the end message monitored that RRU reports within the previous SRS cycle, determine the SRS of each RRU in the room subsystem that receives; According to the SRS of described each RRU, determine to comprise the RRU that the SRS of target terminal information is corresponding; The RRU selecting quality of reception maximum corresponding from the RRU that described SRS is corresponding, and using RRU corresponding for described quality of reception maximum as described terminal at the front RRU once accessed.
Particularly, according to the end message monitored that RRU reports within the previous SRS cycle, BBU is received in the information transmitted in special duration, described information is formed by the SRS symbol splicing in multiple RRU SRS cycle, the corresponding same terminal of SRS symbol of described at least two different RRU; The SRS symbol of each RRU is determined from described information, and using the position of the position of described each RRU as terminal corresponding to the SRS symbol of the described each RRU determined; The RRU that the RRU selecting signal quality best from described different RRU accesses as described target terminal.
Wherein, the process that SRS symbol splicing in the SRS cycle of multiple RRU is formed is: suppose currently have 2 RRU, each RRU generates two SRS symbols, according to two RRU marks, simultaneously receive four SRS symbols is lined up a sequence.The effect done like this is, because SRS symbol can not superpose each other in sequence, can distribute corresponding duration and transmit after Base Band Unit receives this sequence.
In order to describe the deterministic process of above-mentioned special duration in detail, the embodiment of the present invention provides Fig. 2, is illustrated by concrete example.
Suppose in community 0, there are 8 RRU, each RRU serves 50 user terminals in this region, each RRU produces 2 SRS symbols (2 SRS symbols are multiplexing by 50 user terminals) within each SRS cycle, so 8 RRU just create 16 SRS symbols, 14 SRS symbols can only be transmitted based on 1ms, therefore 2ms can be able to be selected from the first collection period 1000ms to be used for transmission 16 SRS symbols, also can be interrupted from the second collection period 1000ms and choose two durations and be used for transmission 16 SRS symbols, the summation of certain two durations is necessarily greater than the duration that 16 SRS symbols take.The concrete value of visible special duration depends on the result of product of the RRU number in a collection period and the SRS symbol numbers in the SRS cycle, special duration can be long for consecutive hours, also can be multiple summations long in short-term, certain special duration can not be greater than collection period, can be transmitted SRS symbol separately by special duration.
After special duration is determined according to above-mentioned defining method, just can according to receiving the RRU once accessed before relevant information is determined in special duration, concrete deterministic process is as follows.
For example, as shown in Figure 3, community 0 connects two expanding elements by a baseband processing unit, and each expanding element connects four RRU, has worked in coordination with common cell signal and has covered.The SRS cycle supposing current area is 10ms, and be 50 owing to covering terminal use under each RRU, therefore a SRS cycle comprises 2 SRS symbols, and in fact, the number of SRS symbol is determined by terminal use's number.
Because this community comprises 8 RRU, each SRS cycle comprises 2 SRS symbols, and therefore, special duration can value be 2ms, therefore chooses 2ms as special duration inside a collection period 1000ms, for transmitting the SRS symbol of each RRU.Baseband processing unit is by the SRS symbol of each RRU of independent parsing, and user terminal resident under can determining each RRU, is defined as the position of terminal by the position of affiliated RRU.Target terminal 0 is belonged to the situation of multiple RRU, then the RRU0 selecting signal quality best is as the position of this target terminal.
Consider that indoor distributed system existed the problem covered, in order to avoid terminal is located by mistake, the embodiment of the present invention introduces the concept of intercommunication characteristic value, according to the intercommunication characteristic value in the room subsystem pre-set between RRU, from all RRU monitoring target terminal, determine the RRU with the locus intercommunication of the front RRU once accessed.
Wherein, intercommunication characteristic value in the subsystem of room between RRU derives from the system parameters during subsystem networking of room, if the intercommunication characteristic value wherein between two RRU in the subsystem of described room is effective value, then show that the locus of described two RRU representative is intercommunication; If the intercommunication characteristic value wherein between two RRU in the subsystem of described room is invalid value, then show that the locus of described two RRU representative does not communicate.Characteristic value is mainly in order to whether the locus characterized in indoor distributed system representated by each RRU communicates, a such as building, building, room A and room B belongs to the room in remote two floors, and it is not connected, in setting-up time section, terminal can not move to room B from room A in other words conj.or perhaps, therefore can represent that the RRUA that the RRUA that room A is corresponding and room B is corresponding does not communicate by arranging this intercommunication characteristic value, therefore the intercommunication characteristic value between RRUA and RRUB is invalid, same reason, suppose in a same building, building, room C and room D be near two rooms, and communicate with each other, in setting-up time section, terminal can move to room D from room C in other words conj.or perhaps, therefore can represent that the RRUD that the RRUC that room C is corresponding and room D is corresponding communicates by arranging this intercommunication characteristic value, therefore the intercommunication characteristic value between RRUA and RRUB is effective.
Based on the introducing of above-mentioned characteristic value, the embodiment of the present invention further using intercommunication characteristic value and the front RRU once accessed as screening conditions, the positioning result of current target terminal is screened, obtains the most accurate result.Particularly, according to described intercommunication characteristic value, if there is the RRU with the locus intercommunication of the front RRU once accessed from all RRU monitoring target terminal, then the RRU selecting signal quality best from all RRU determined.
Still with an above-mentioned building, building for example, the RRU once accessed before target terminal is RRUC, prove that target terminal is at room C, monitor in addition in all RRU of target terminal and there is RRUd and RRUa, in view of the intercommunication characteristic value of known RRUc and RRUd is effective, the intercommunication characteristic value of RRUa and RRUc is invalid, therefore select the RRU that RRUd accesses as current target terminal, and the room D at RRUd place is as the position of target terminal.
In addition, if current the orientating as of described target terminal is accessed first, the RRU once accessed before namely not existing, then, from all RRU monitoring target terminal, select the position of the best RRU of the quality of reception as the current position of described target terminal.
Such as, monitor in all RRU of target terminal and there is RRUa, RRUb and RRUc, and target terminal this time access for access first, then selects the RRUa of signal quality the best, using the current location of the position of RRUa as target terminal from RRUa, RRUb and RRUc.
On the other hand, if from all RRU monitoring target terminal, determine to there is not the RRU with the locus intercommunication of the front RRU once accessed, then monitor all RRU of target terminal from described, select the position of the best RRU of signal quality as the current position of described target terminal.
For example, the RRU once accessed before target terminal is RRUC, prove that a front localizing objects terminal is at room C, monitor in addition in all RRU of target terminal and there is RRUa and RRUb, known, the intercommunication characteristic value of RRUa and RRUb and RRUc is invalid value, therefore, the current RRUa selecting signal quality best from RRUa and RRUb, and using the position of RRUa as the current position of described target terminal.In addition, in order to avoid the inaccurate of a front positioning result causes follow-up determination result to occur error, this place increases fault tolerant mechanism further, such as, if target terminal initial alignment target terminal is at the room C at RRUc place, all do not exist and the effective RRU of RRUc intercommunication characteristic value in the positioning result that follow-up N continuous is secondary, now, judge that target terminal initial alignment result exists deviation, the positioning result of initial target terminal is made correction, be modified to the RRU intercommunication with next positioning result, and the RRU that locus is adjacent.
Below by concrete example system, the process of above-mentioned room subsystem localizing objects terminal is described, as shown in Figure 4.
Fig. 4 small area 0 connects two expanding elements by a baseband processing unit, and each expanding element connects six BBU, has worked in coordination with the common MPS process of the building to four floors.In the diagram, the intercommunication characteristic value between 12 BBU as shown in Table 1.
Table one:
The intercommunication characteristic value do not identified in table one between effective RRU is invalid.If in the T0 moment of first locating periodically, the extension unit that may be belonged to by location acquisition terminal 0 comprises RRU2, RRU1, wherein the quality of reception of RRU2 is 100, the quality of reception of RRU1 is 90, quality of reception value is higher, represent that the quality of reception is better, therefore select the positioning result of RRU2 as terminal 0 of quality of reception the best.
If in the T1 moment of second locating periodically, the extension unit that may be belonged to by location acquisition terminal 0 comprises extension unit 2, extension unit 1, wherein the quality of reception of extension unit 2 is 85, the quality of reception of extension unit 1 is 105, now, network optimization system by this building, building is learnt terminal 0 is positioned at below RRU2, due to the position ownership that RRU1 is this cycle location optimum reception quality, and know that the characteristic value between RRU1 and RRU2 is effective from table one, therefore, determine the T1 moment, the position of terminal is attributed to RRU1.
If in the T2 moment of the 3rd locating periodically, the extension unit that may be belonged to by location acquisition terminal 0 comprises RRU1, RRU0, RRU3, wherein the quality of reception of RRU1 is 85, the quality of reception of RRU0 is 95, the quality of reception of RRU3 is 98, now, know that last week, terminal 0 was positioned at below RRU1 according to second locating periodically positioning result, although RRU3 is the terminal location ownership of this cycle optimum reception quality, but know that the intercommunication characteristic value between RRU3 and RRU1 is invalid from table one, therefore, RRU3 is irrational position, rejected, so comprise RRU1 from the extension unit that may belong to, RRU0, RRU0 is selected in RRU3, continue to judge RRU0 whether as the final positioning result of terminal 0 according to table one, know from table one, intercommunication characteristic value due to RRU0 and RRU1 is effective, and RRU0 is legal optimum reception Remote Radio Unit, therefore determine that RRU0 is the final positioning result of terminal 0.Follow-up position fixing process is similar, no longer sets forth.
Visible by the present embodiment, based on this terminal last initial position RRU between characteristic value, in the T2 moment of the 3rd locating periodically, effective rejecting terminal 0 belongs to the erroneous judgement of RRU3, avoid RRU3 signal to cross and cover 1st floor and cause positioning result to occur the problem that floor is judged by accident, promote Position location accuracy, for location-based business provides reliable locating information.
Based on identical technical conceive, the embodiment of the present invention also provides a kind of room subsystem positioner, and this device can perform said method embodiment.The device that the embodiment of the present invention provides as shown in Figure 5, comprising: judging unit 401, determine access RRU unit 402, determine intercommunication RRU unit 403, determine position units 404, wherein:
Judging unit 401, for the end message monitored reported according to each radio frequency remote unit RRU received, has judged whether that at least two RRU monitor target terminal;
Determine the RRU unit 402 accessed, if for there being at least two RRU to monitor target terminal, the RRU once accessed before determining described target terminal;
Determine the RRU unit 403 of intercommunication, for from all RRU monitoring target terminal, determine the RRU with the locus intercommunication of the front RRU once accessed;
Determine position units 404, for selecting a RRU in the RRU from the locus intercommunication determined, and using the position of the 2nd RRU selected as the current position of described target terminal.
Under this special application scenarios of room subsystem, a usual community covers by multiple RRU is collaborative to promote MPS process area, and the signal between multiple RRU is by returning to baseband processing unit (BuildingBasebandUnit after superposition, BBU) demodulation, in light of this situation, the described RRU unit 402 determining to access, specifically for the end message monitored that reports within the previous SRS cycle according to RRU, determines the SRS of each RRU in the room subsystem that receives; According to the SRS of described each RRU, determine to comprise the RRU that the SRS of target terminal information is corresponding; The RRU selecting quality of reception maximum corresponding from the RRU that described SRS is corresponding, and using RRU corresponding for described quality of reception maximum as described terminal at the front RRU once accessed.
Particularly, according to the end message monitored that RRU reports within the previous SRS cycle, BBU is received in the information transmitted in special duration, described information is formed by the SRS symbol splicing in multiple RRU SRS cycle, the corresponding same terminal of SRS symbol of described at least two different RRU; The SRS symbol of each RRU is determined from described information, and using the position of the position of described each RRU as terminal corresponding to the SRS symbol of the described each RRU determined; The RRU that the RRU selecting signal quality best from described different RRU accesses as described target terminal.
Wherein, the process that SRS symbol splicing in the SRS cycle of multiple RRU is formed is: suppose currently have 2 RRU, each RRU generates two SRS symbols, according to two RRU marks, simultaneously receive four SRS symbols is lined up a sequence.The effect done like this is, because SRS symbol can not superpose each other in sequence, can distribute corresponding duration and transmit after Base Band Unit receives this sequence.
In order to describe the deterministic process of above-mentioned special duration in detail, the embodiment of the present invention provides Fig. 2, is illustrated by concrete example.
Suppose in community 0, there are 8 RRU, each RRU serves 50 user terminals in this region, each RRU produces 2 SRS symbols (2 SRS symbols are multiplexing by 50 user terminals) within each SRS cycle, so 8 RRU just create 16 SRS symbols, 14 SRS symbols can only be transmitted based on 1ms, therefore 2ms can be able to be selected from the first collection period 1000ms to be used for transmission 16 SRS symbols, also can be interrupted from the second collection period 1000ms and choose two durations and be used for transmission 16 SRS symbols, the summation of certain two durations is necessarily greater than the duration that 16 SRS symbols take.The concrete value of visible special duration depends on the result of product of the RRU number in a collection period and the SRS symbol numbers in the SRS cycle, special duration can be long for consecutive hours, also can be multiple summations long in short-term, certain special duration can not be greater than collection period, can be transmitted SRS symbol separately by special duration.
