Abstract
The invention discloses an LMU (location measurement unit) selection method and an LMU selection device. The LMU selection method comprises the following steps that: an E-SMLC (enhanced serving mobile location centre) receives the LMU auxiliary information sent by an access-side network element; and the E-SMLC selects an LMU set participating in the positioning location of this time according to the LMU auxiliary information. With the adoption of the LMU selection method and the LMU selection device disclosed by the invention, the problem that the E-SMLC only knows the base station serving UE (user equipment) and a cell identify, and cannot know the approximate location of the UE and then select an LMU adjacent to the UE to measure is solved.
Description
Technical field
The present invention relates to the communications field, in particular to LMU system of selection and device.
Background technology
UTDOA (Uplink Time Difference Of Arrival, the up link timesharing arrives) be that a kind of service Mobility Center take evolution is as the basis, take the base station as auxiliary (eNB-assisted, E-SMLC (Enhanced Serving Mobile Location Centre, the service Mobility Center of evolution) Based) localization method.In the UTDOA system, LMU (Location Measurement Unit, location measurement unit) carries out and measures operation, and E-SMLC obtains carrying out the positional information that location Calculation obtains UE (User Equipment, subscriber equipment) after the measurement result.
Concrete, after E-SMLC received Location Request, the request service base station was UE configuration SRS (Sounding Reference Signal, sound reference signal) parameter, after finishing after the serving BS configuration this SRS configuration parameter was informed E-SMLC.E-SMLC sends to a plurality of Different L MU with the SRS configuration parameter again, the SRS configuration parameter that a plurality of LMU send according to E-SMLC receives the uplink SRS reference signal that UE sends simultaneously, and receiving time information sent to E-SMLC, E-SMLC receives the SRS time difference according to Different L MU UE is positioned calculating.
Pass through LPPa (LTE Positioning Protocol Annex between base station and E-SMLC, long evolving system location Additional Agreement) communicates, LMU and E-SMLC communicate by LMUp (Location Measuring Unit Protocol, location measurement unit agreement).LMU has two types: independent LMU entity (Stand-alone) or integrated LMU (integrated is integrated in the base station).Normally, Stand-alone LMU and base station are total to location (that is, both common antenna).Integrated LMU and base station share radio-cell and antenna.LMU may be logical ne or be connected with the base station or be integrated in the base station independently.In transparent (transparent) framework, the LMUp agreement between Stand-alone LMU and integrated LMU and the E-SMLC is all passed through the SLm interface and is set up; And in mixing (hybrid) framework, the LMUp agreement between Stand-alone LMU and the E-SMLC is set up by the SLm interface, and the LMUp agreement between integrated LMU and the E-SMLC is set up by the LPPa interface.In the UTDOA method, the LPPa agreement can be used for transferring auxiliary data, and measurement result is transmitted to E-SMLC in the base station that also can be used for integrated LMU under the hybrid framework; The LMUp agreement is used for LMU and transmits measurement result to E-SMLC, also can be used for transmitting LMU for information about (for example, link monitoring).
Fig. 1 has described the framework of UTDOA navigation system, in the UTDOA system, for same Location Request, a plurality of LMU carry out simultaneously and measure operation and measurement result is sent to E-SMLC, and E-SMLC obtains carrying out the positional information that location Calculation obtains UE after the measurement result.LMU can be divided into two types of independent LMU and integrated LMU.Independent LMU may with the base station shared antenna, and integrated LMU is integrated in the base station.E-SMLC connects by SLs interface and MME (Mobility Management Entity, mobile management entity), and MME passes through the S1 interface and is connected with the base station, and then mutual LPPa protocol message is connected by this SLs and is connected transmission with S1 between E-SMLC and base station.Integrated LMU can set up that LPPa is connected with E-SMLC or SLm connects, and independent LMU can set up SLm with E-SMLC and be connected, and then mutual LMUp protocol message can be connected or LPPa connection transmission by SLm between E-SMLC and LMU.
In sum, E-SMLC need to know the geographical topology information of LMU, and for example geographical location information, affiliated base station or affiliated cell information could be the LMU set that UE selects to participate in this positioning action.Because E-SMLC is location-server, may not have the geographical location information of base station, if therefore E-SMLC only knows base station and the cell ID of service UE, can not know the Position Approximate of UE, measure with the LMU that selects contiguous UE.
Only know base station and the cell ID of service UE for E-SMLC in the correlation technique, can not know the Position Approximate of UE, the problem so that the LMU that selects contiguous UE measures not yet proposes effective solution at present.
