Shown in Figure 1, the embodiment of the present invention provides a kind of room subsystem localization method flow diagram, specifically realizes
Method includes:
Step S101, according to the end message monitored that each radio frequency remote unit RRU received reports, judgement is
It is no to there are at least two RRU to monitor target terminal.
Step S102 is determined and is once accessed before the target terminal if there is at least two RRU monitor target terminal
First RRU.
Step S103, from all RRU for monitoring target terminal, the determining space with preceding the first RRU once accessed
The RRU of position intercommunication.
Step S104 selects a RRU from the RRU of determining intercommunication, and by the position of the 2nd RRU of the RRU of selection
The position current as the target terminal.
Wherein, the RRU of so-called spatial position intercommunication refers to the space where the first RRU and the space where the 2nd RRU
Be geographically it is interconnected, i.e., terminal can be moved to the 2nd RRU from the first RRU.
Under this special application scenarios of room subsystem, a usual cell is small to be promoted by multiple RRU collaboration covering
Area's area coverage, and the signal between multiple RRU is by returning to baseband processing unit (Building Base band after superposition
Unit, BBU) demodulation, in light of this situation, the terminal in the subsystem of room constantly can report information to RRU, and then RRU is collected
Terminal reports information, and the end message monitored can be reported to BBU every a SRS period.According to RRU in previous SRS
The end message monitored reported in period determines the SRS of each RRU in received room subsystem；According to each RRU
SRS, determine include target terminal information the corresponding RRU of SRS；Select the quality of reception maximum from the corresponding RRU of the SRS
It is worth corresponding RRU, and using the corresponding RRU of the quality of reception maximum value as the terminal in preceding the first RRU once accessed.
Specifically, the end message monitored reported within the previous SRS period according to RRU, BBU are received when special
The information transmitted in long, the information is that the SRS symbol splicing in a SRS period by multiple RRU is formed, it is described extremely
The SRS symbol of few two different RRU corresponds to the same terminal；The SRS symbol of each RRU is determined from the information, and will
Position of the position of each RRU as the corresponding terminal of SRS symbol of determining each RRU；From described different
The RRU that the top-quality RRU of selection signal is accessed as the target terminal in RRU.
Wherein, the process that the SRS symbol splicing in a SRS period of multiple RRU is formed are as follows: assuming that currently having 2
A RRU, each RRU generate two SRS symbols, are identified according to two RRU, will line up one by received four SRS symbols simultaneously
Sequence.This have the effect that because SRS symbol will not be superimposed between each other in sequence, when Base Band Unit receives this
Corresponding duration can be distributed after sequence to be transmitted.
In order to which the determination process of above-mentioned special duration is described in detail, the embodiment of the present invention provides Fig. 2, is said by concrete example
It is bright.
Assuming that having 8 RRU, each RRU to service 50 user terminals in the region in cell 0, each RRU is each
2 SRS symbols (2 SRS symbols are multiplexed by 50 user terminals) are generated in the SRS period, then 8 RRU just produce 16
SRS symbol can only transmit 14 SRS symbols based on 1ms, therefore can choose 2ms from the first collection period 1000ms
For transmitting 16 SRS symbols, two durations of selection can also be interrupted from the second collection period 1000ms and are used to transmit 16
SRS symbol, the summation of certain two durations are centainly greater than the duration of 16 SRS symbols occupancy.It can be seen that special duration specifically takes
Value depends on the result of product of RRU number in a collection period and the SRS symbol numbers in a SRS period, when special
Length can be long for consecutive hours, is also possible to multiple summations long in short-term, and certain special duration can not be greater than collection period, pass through
Special duration can individually be transmitted SRS symbol.
After special duration is determined according to above-mentioned determining method, so that it may believe according to correlation is received in special duration
The first RRU that breath once accesses before determining, specific determination process are as follows.
For example, as shown in figure 3, cell 0 connects two expanding elements by a baseband processing unit, each extension is single
Cell signal covering altogether is completed in member four RRU of connection, collaboration.Assuming that the SRS period of current area is 10ms, due to each RRU
Lower covering terminal user is 50, therefore includes 2 SRS symbols in a SRS period, in fact, the number of SRS symbol is by end
End subscriber number determines.
Since this cell includes 8 RRU, each SRS period includes 2 SRS symbols, and therefore, special duration can be with value
For 2ms, therefore 2ms is chosen inside a collection period 1000ms as special duration, for transmitting the SRS symbol of each RRU.
Baseband processing unit passes through the SRS symbol of each RRU of independent parsing, the user terminal being resident under each RRU can be determined, by institute
The position of the RRU of category is determined as the position of terminal.The case where multiple RRU are belonged to for target terminal 0, then selection signal quality
Position of the best RRU0 as the target terminal.
In view of there is covering in indoor distributed system, in order to avoid terminal is accidentally positioned, the embodiment of the present invention
The concept for introducing intercommunication characteristic value, according to the intercommunication characteristic value between RRU in pre-set room subsystem, from monitoring target
In all RRU of terminal, the RRU of the determining spatial position intercommunication with preceding the first RRU once accessed.
Wherein, the system parameter when intercommunication characteristic value in the subsystem of room between RRU is from the network construction of room subsystem,
If the intercommunication characteristic value between two of them RRU in the room subsystem is virtual value, show what described two RRU were represented
Spatial position is intercommunication；If the intercommunication characteristic value between two of them RRU in the room subsystem is invalid value, show
The spatial position that described two RRU are represented is not communicated with.Characteristic value is primarily to characterize each RRU institute's generation in indoor distributed system
Whether the spatial position of table communicates, such as a building building, and room A and room B belong to the room in remote two floors,
And it is not connected, or perhaps terminal can not be moved to room B from room A in the set time period, therefore by the way that this is arranged
Intercommunication characteristic value can indicate that the corresponding RRUA of room A corresponding RRUA and room B is not communicated with, thus RRUA and RRUB it
Between intercommunication characteristic value be invalid, same reason, it is assumed that in same building building, room C and room D are two abutted
A room, and communicate with each other, or perhaps terminal can be moved to room D from room C in the set time period, therefore by setting
Setting this intercommunication characteristic value can indicate that the corresponding RRUD of room C corresponding RRUC and room D is communicated, therefore RRUA and RRUB
Between intercommunication characteristic value be effective.
Based on the introducing of features described above value, the embodiment of the present invention is further by intercommunication characteristic value and preceding once accessed
One RRU screens the positioning result of current target terminal as screening conditions, obtains most accurate result.Specifically, root
According to the intercommunication characteristic value, if there is the space with preceding the first RRU once accessed from all RRU for monitor target terminal
The RRU of position intercommunication, the then top-quality RRU of selection signal from determining all RRU.
Still for example with above-mentioned building building, the first RRU once accessed before target terminal is RRUC, it was demonstrated that target
In addition terminal monitors that there are RRUd and RRUa in all RRU of target terminal, in view of known RRUc's and RRUd in room C
Intercommunication characteristic value is effectively that the intercommunication characteristic value of RRUa and RRUc are invalid, therefore select RRUd as current goal end
Terminate into RRU, and position of the room D as target terminal where RRUd.
In addition, preceding the first RRU once accessed is not present, then if the target terminal is currently positioned as accessing for the first time
From all RRU for monitoring target terminal, the position for the RRU for selecting the quality of reception best is as the target terminal
Current position.
For example, monitoring that there are RRUa, RRUb and RRUc in all RRU of target terminal, and target terminal this time connects
Enter to access for the first time, then from RRUa, RRUb and RRUc optimal RRUa of selection signal quality, using the position of RRUa as target end
The current location at end.
On the other hand, it if from all RRU for monitoring target terminal, determines and is not present and preceding first once accessed
The RRU of the spatial position intercommunication of RRU, then from all RRU for monitoring target terminal, selection signal is top-quality
The position of the RRU position current as the target terminal.
For example, the first RRU once accessed before target terminal is RRUC, it was demonstrated that preceding primary positioning target terminal is in room
Between C, in addition monitor that there are RRUa and RRUb in all RRU of target terminal, it was known that the intercommunication of RRUa and RRUb and RRUc is special
Value indicative is invalid value, therefore, the current top-quality RRUa of selection signal from RRUa and RRUb, and the position of RRUa is made
For the current position of the target terminal.In addition, in order to avoid the inaccuracy of a preceding positioning result causes subsequent definitive result
There is error, fault tolerant mechanism is further increased at this, for example, if target terminal initial alignment target terminal is in the room where RRUc
Between C, in the positioning result of subsequent continuous n times there is no with the RRUc effective RRU of intercommunication characteristic value, at this point, judge that target is whole
Holding initial alignment result, there are deviations, and the positioning result of initial target terminal is made amendment, are modified to and next positioning result
RRU intercommunication, and the RRU that spatial position is adjacent.
The process that above-mentioned room subsystem positioning target terminal is systematically described below by specific example, such as Fig. 4 institute
Show.
Cell 0 connects two expanding elements by a baseband processing unit in Fig. 4, and each expanding element connects six BBU,
The total MPS process to the building of four floors is completed in collaboration.In Fig. 4, the intercommunication characteristic value between 12 BBU is as shown in Table 1.
Table one:
The intercommunication characteristic value not identified between effective RRU in table one is invalid.If in the T0 of first locating periodically
Moment, by positioning obtain terminal 0 may the extension unit of ownership include RRU2, RRU1, wherein the quality of reception of RRU2 is
100, the RRU1 quality of reception is 90, and quality of reception value is higher, indicates that the quality of reception is better, therefore select the quality of reception best
Positioning result of the RRU2 as terminal 0.
If at the T1 moment of second locating periodically, the extension unit that obtaining terminal 0 by positioning may belong to includes
Extension unit 2, extension unit 1, wherein the quality of reception of extension unit 2 is 85, and the quality of reception of extension unit 1 is 105, this
When, learn that terminal 0 is located at RRU2 in the following, since RRU1 is that the positioning of this period is best on the network optimization system by the building building
The position of the quality of reception belongs to, and knows that the characteristic value between RRU1 and RRU2 is effective from table one, accordingly, it is determined that the T1 moment, whole
The position at end is attributed to RRU1.
If at the T2 moment of third locating periodically, the extension unit that obtaining terminal 0 by positioning may belong to includes
RRU1, RRU0, RRU3, the quality of reception that the quality of reception that wherein quality of reception of RRU1 is 85, RRU0 is 95, RRU3 is 98,
At this point, knowing that terminal last week 0 is located at RRU1 in the following, although RRU3 is that this period is best according to second locating periodically positioning result
The terminal location of the quality of reception belongs to, but from table one know the intercommunication characteristic value between RRU3 and RRU1 be it is invalid, therefore, RRU 3
It for unreasonable position, is rejected, includes then RRU1, RRU0 from the extension unit that may belong to, select RRU0 in RRU3,
Continue according to table one determine RRU0 whether be terminal 0 final positioning result, know from table one, due to the intercommunication of RRU0 and RRU1
Characteristic value is effective, and RRU0 is legal optimum reception Remote Radio Unit, it is thus determined that RRU0 is the final positioning of terminal 0
As a result.Subsequent position fixing process is similar, no longer illustrates.
Through this embodiment as it can be seen that characteristic value between the initial position RRU based on the terminal last, positions in third
The T2 moment in period effectively rejects the erroneous judgement that terminal 0 belongs to RRU3, avoids RRU3 signal and cross and cover 1 building and cause to position
As a result there is the problem of floor erroneous judgement, promote positioning accuracy, provide reliable location information for location-based business.
Based on the same technical idea, the embodiment of the present invention also provides a kind of room subsystem positioning device, which can hold
Row above method embodiment.Device provided in an embodiment of the present invention is as shown in Figure 5, comprising: judging unit 401 determines access
RRU unit 402, determines position units 404 at the RRU unit 403 for determining intercommunication, in which:
Judging unit 401, the terminal letter monitored for being reported according to each radio frequency remote unit RRU received
Breath, judges whether there is at least two RRU and monitors target terminal；
Determine that the RRU unit 402 of access determines the target for monitoring target terminal if there is at least two RRU
The first RRU once accessed before terminal；
The RRU unit 403 for determining intercommunication, for determining and preceding primary access from all RRU for monitoring target terminal
The first RRU spatial position intercommunication RRU；
Position units 404 are determined, for selecting a RRU from the RRU of determining spatial position intercommunication, and by selection
The position of the 2nd RRU position current as the target terminal.
Under this special application scenarios of room subsystem, a usual cell is small to be promoted by multiple RRU collaboration covering
Area's area coverage, and the signal between multiple RRU is by returning to baseband processing unit (Building Base band after superposition
Unit, BBU) demodulation, in light of this situation, the RRU unit 402 of the determining access is specifically used for: according to RRU previous
The end message monitored reported in the SRS period determines the SRS of each RRU in received room subsystem；According to described each
The SRS of RRU determines the corresponding RRU of SRS comprising target terminal information；The quality of reception is selected from the corresponding RRU of the SRS
The corresponding RRU of maximum value, and using the corresponding RRU of the quality of reception maximum value as the terminal in preceding first once accessed
RRU。
Specifically, the end message monitored reported within the previous SRS period according to RRU, BBU are received special
The information transmitted in duration, the information is that the SRS symbol splicing in a SRS period by multiple RRU is formed, described
The SRS symbol of at least two different RRU corresponds to the same terminal；The SRS symbol of each RRU is determined from the information, and
Using the position of each RRU as the position of the corresponding terminal of SRS symbol of determining each RRU；From the difference
RRU in the RRU that is accessed as the target terminal of the top-quality RRU of selection signal.
Wherein, the process that the SRS symbol splicing in a SRS period of multiple RRU is formed are as follows: assuming that currently having 2
A RRU, each RRU generate two SRS symbols, are identified according to two RRU, will line up one by received four SRS symbols simultaneously
Sequence.This have the effect that because SRS symbol will not be superimposed between each other in sequence, when Base Band Unit receives this
Corresponding duration can be distributed after sequence to be transmitted.
In order to which the determination process of above-mentioned special duration is described in detail, the embodiment of the present invention provides Fig. 2, is said by concrete example
It is bright.
Assuming that having 8 RRU, each RRU to service 50 user terminals in the region in cell 0, each RRU is each
2 SRS symbols (2 SRS symbols are multiplexed by 50 user terminals) are generated in the SRS period, then 8 RRU just produce 16
SRS symbol can only transmit 14 SRS symbols based on 1ms, therefore can choose 2ms from the first collection period 1000ms
For transmitting 16 SRS symbols, two durations of selection can also be interrupted from the second collection period 1000ms and are used to transmit 16
SRS symbol, the summation of certain two durations are centainly greater than the duration of 16 SRS symbols occupancy.It can be seen that special duration specifically takes
Value depends on the result of product of RRU number in a collection period and the SRS symbol numbers in a SRS period, when special
Length can be long for consecutive hours, is also possible to multiple summations long in short-term, and certain special duration can not be greater than collection period, pass through
Special duration can individually be transmitted SRS symbol.
After special duration is determined according to above-mentioned determining method, so that it may believe according to correlation is received in special duration
The first RRU that breath once accesses before determining, specific determination process are as follows.
For example, as shown in figure 3, cell 0 connects two expanding elements by a baseband processing unit, each extension is single
Cell signal covering altogether is completed in member four RRU of connection, collaboration.Assuming that the SRS period of current area is 10ms, due to each RRU
Lower covering terminal user is 50, thus in a SRS period include 2 SRS symbols, in fact, the number of SRS symbol by
Terminal user's number determines.
Since this cell includes 8 RRU, each SRS period includes 2 SRS symbols, and therefore, special duration can be with value
For 2ms, therefore 2ms is chosen inside a collection period 1000ms as special duration, for transmitting the SRS symbol of each RRU.
Baseband processing unit passes through the SRS symbol of each RRU of independent parsing, the user terminal being resident under each RRU can be determined, by institute
The position of the RRU of category is determined as the position of terminal.The case where multiple RRU are belonged to for target terminal 0, then selection signal quality
Position of the best RRU0 as the target terminal.
In view of there is covering in indoor distributed system, in order to avoid terminal is accidentally positioned, the embodiment of the present invention
The concept of intercommunication characteristic value is introduced, the RRU unit 403 of the determining intercommunication is specifically used for: according to pre-set room subsystem
Intercommunication characteristic value between interior RRU, it is determining with preceding the first RRU's once accessed from all RRU for monitoring target terminal
The RRU of spatial position intercommunication.
Wherein, the system parameter when intercommunication characteristic value in the subsystem of room between RRU is from the network construction of room subsystem,
If the intercommunication characteristic value between two of them RRU in the room subsystem is virtual value, show what described two RRU were represented
Spatial position is intercommunication；If the intercommunication characteristic value between two of them RRU in the room subsystem is invalid value, show
The spatial position that described two RRU are represented is not communicated with.Characteristic value is primarily to characterize each RRU institute's generation in indoor distributed system
Whether the spatial position of table communicates, such as a building building, and room A and room B belong to the room in remote two floors,
And it is not connected, or perhaps terminal can not be moved to room B from room A in the set time period, therefore by the way that this is arranged
Intercommunication characteristic value can indicate that the corresponding RRUA of room A corresponding RRUA and room B is not communicated with, thus RRUA and RRUB it
Between intercommunication characteristic value be invalid, same reason, it is assumed that in same building building, room C and room D are two abutted
A room, and communicate with each other, or perhaps terminal can be moved to room D from room C in the set time period, therefore by setting
Setting this intercommunication characteristic value can indicate that the corresponding RRUD of room C corresponding RRUC and room D is communicated, therefore RRUA and RRUB
Between intercommunication characteristic value be effective.
Based on the introducing of features described above value, the embodiment of the present invention is further by intercommunication characteristic value and preceding once accessed
One RRU screens the positioning result of current target terminal as screening conditions, obtains most accurate result.Specifically,
According to the intercommunication characteristic value, if there is the sky with preceding the first RRU once accessed from all RRU for monitor target terminal
Between position intercommunication RRU, the determining position units are specifically used for: selection signal is top-quality from determining all RRU
RRU。
Still for example with above-mentioned building building, the first RRU once accessed before target terminal is RRUC, it was demonstrated that target
In addition terminal monitors that there are RRUD and RRUA in all RRU of target terminal, in view of known RRUC's and RRUD in room C
Intercommunication characteristic value is effectively that the intercommunication characteristic value of RRUA and RRUC are invalid, therefore select RRUD as current goal end
Terminate into RRU, and position of the room D as target terminal where RRUD.
Further, if preceding the first RRU once accessed, the determining position units 404 are not present in the target terminal
Be also used to: from all RRU for monitoring target terminal, the position for the RRU for selecting the quality of reception best is as the mesh
Mark the current position of terminal.
For example, monitoring that there are RRUa, RRUb and RRUc in all RRU of target terminal, and target terminal this time connects
Enter to access for the first time, then from RRUa, RRUb and RRUc optimal RRUa of selection signal quality, using the position of RRUa as target end
The current location at end.
Further, it if from all RRU for monitoring target terminal, determines and is not present and preceding first once accessed
The RRU of the spatial position intercommunication of RRU, determines position units 404, is also used to: from all RRU for monitoring target terminal
In, the position of the top-quality RRU of the selection signal position current as the target terminal.
For example, the first RRU once accessed before target terminal is RRUC, it was demonstrated that preceding primary positioning target terminal is in room
Between C, in addition monitor that there are RRUa and RRUb in all RRU of target terminal, it was known that the intercommunication of RRUa and RRUb and RRUc is special
Value indicative is invalid value, therefore, the current top-quality RRUa of selection signal from RRUa and RRUb, and the position of RRUa is made
For the current position of the target terminal.In addition, in order to avoid the inaccuracy of a preceding positioning result causes subsequent definitive result
There is error, fault tolerant mechanism is further increased at this, for example, if target terminal initial alignment target terminal is in the room where RRUc
Between C, in the positioning result of subsequent continuous n times there is no with the RRUc effective RRU of intercommunication characteristic value, at this point, judge that target is whole
Holding initial alignment result, there are deviations, and the positioning result of initial target terminal is made amendment, are modified to and next positioning result
RRU intercommunication, and the RRU that spatial position is adjacent.
To sum up, the on the one hand terminal monitored that the embodiment of the present invention is reported in positioning according to each RRU received
Information judges whether there is at least two RRU and monitors target terminal；If there is at least two RRU monitor target terminal, then need
It to be selected according to the first RRU once accessed before the determination target terminal as screening conditions；On the other hand from monitoring
Into all RRU of target terminal, the RRU of the determining spatial position intercommunication with preceding the first RRU once accessed, and from determining
A RRU, and the position that the position of the 2nd RRU selected is current as the target terminal are selected in the RRU of intercommunication.It can
See, finally determines that the current position of target terminal have passed through the judgement of two layers of screening conditions, it finally will be caused by covering problem
Erroneous judgement situation filters out, so that the result of positioning is more accurate.
