In the present embodiment, can be in existing AP network, newly-increased location-server, and, between this location-server and the Surveillance center communication interface is arranged.When Surveillance center needs positioning UE, then send the request message of positioning user terminal to this location-server.

102, location-server obtains the sign that needs place, located subscriber terminal access point apparatus;

In the present embodiment, the sign of access point apparatus can for the numbering of AP (ID, Identity), Service Area Identifier (SAI, Service Area Identifier) or cell id (Cell ID, Cell Identity).

Location-server is before receiving the request message of positioning user terminal; Location-server can obtain the corresponding relation of the sign of the identification code that needs the located subscriber terminal and this user terminal place access point apparatus earlier; And this corresponding relation is stored in second mapping table; The identification code of user terminal can be international mobile subscriber identity (IMSI; International mobile subscriber identity) or mobile subscriber's international number (MSISDN, Mobile Station Integrated Services Digital Network).For example, when the UE in the needs location attempted residing among the AP, UE can initiate location area updating (LAU; Location AreaUpdate) or Routing Area Update operations such as (RAU, Route Area Update), AG can parse the IMSI of this UE that carries in the LAU/RAU message; And can also obtain the corresponding MSISDN of IMSI, can also obtain SAI or the Cell ID of AP simultaneously according to the ID of the resident AP of UE, therefore; AG need can obtain the identification code at located subscriber terminal, i.e. the IMSI of UE or MSISDN are with the sign of this user terminal place access point apparatus; It is the corresponding relation of ID, SAI or the Cell ID of AP; And, when AG is transmitted to CN to LAU/RAU, also can send to location-server to this corresponding relation.In addition, AG also can obtain the IMSI of UE from other existing operating process, for example UE setup requests operation.

In the preceding text, AG can get access to MSISDN from equipment of the core network after obtaining IMSI; Equally; Can in equipment of the core network, preserve the corresponding relation of ID, SAI or the Cell ID of AP, AG can obtain SAI and the Cell ID of AP from equipment of the core network after getting access to the ID of AP.Surveillance center can obtain ID and the Cell ID of AP according to this SAI from equipment of the core network the IMSI according to UE gets access to the SAI of UE place AP from CN after.

Have in positioning server stores under the situation of second mapping table; Can comprise the identification code that needs the located subscriber terminal in the request message of the positioning user terminal that Surveillance center issues, location-server can obtain the sign of the access point apparatus of the identification code correspondence that needs the located subscriber terminal from second mapping table.

It is understandable that; Also can obtain the sign of this UE place access point apparatus by the first identification code of the UE of location as required of Surveillance center; For example, can get access to the SAI of UE place AP from CN according to the IMSI of UE, and will need the sign of place, located subscriber terminal access point apparatus to be carried in the request message of positioning user terminal; In this case, location-server can directly obtain the sign that needs place, located subscriber terminal access point apparatus from this request message.

103, location-server obtains the positional information of the corresponding access point apparatus of the sign of access point apparatus from first mapping table that presets, and first mapping table is preserved the corresponding relation of positional information of sign and the access point apparatus of access point apparatus;

The positional information of access point apparatus can be the latitude and longitude information of AP, or the address information of AP (like No. 44, Chang'an road).

When AP powers on, can distribute parameters such as ID (perhaps being the ID of AP equipment self), SAI and Cell ID, gather the sign that all AP in the network are arranged and the corresponding relation of AP positional information on the location-server, the sign of AP can be ID, SAI or the Cell ID of AP.

104, location-server is to the response message of Surveillance center's transmission positioning user terminal, and the positional information of carrying the access point apparatus that obtains in this message is so that Surveillance center is with the positional information of this positional information as user terminal.

Location-server can obtain the positional information of AP according to this sign after getting access to the sign that needs place, located subscriber terminal AP, and this positional information is informed Surveillance center.Because in the AP network, the coverage of AP is little, therefore, basically in horizon range, therefore, in the present embodiment, Surveillance center can directly belong to the positional information of the positional information of AP as UE with UE between AP and the UE.

Because basically in horizon range, therefore, present embodiment directly belongs to the positional information of the positional information of AP as UE with UE between AP and the UE.Compared with prior art, the AP of present embodiment need not be provided with GPS, does not need calculation of mass data yet; The corresponding relation that only need on location-server, gather sign and the AP positional information of AP in advance; Obtain the sign that needs place, located subscriber terminal AP by location-server, and obtain the positional information of this AP, and inform that Surveillance center gets final product according to this sign; Have and realize simply the advantage that cost is less.And, can only obtain the latitude and longitude information of AP in the prior art, and present embodiment can also obtain the address information of AP, thereby can directly confirm user's addresses information.

AP?ID	SAI	Cell?ID	Address
				AP?ID1	SAI1	Cell?ID1	Address1
AP?ID2	SAI2	Cell?ID2	Address2
				...	...	...	...

Table 1

203, AG receives after the LAU message that AP sends, and parses the IMSI in the LAU message, and the corresponding relation of IMSI and the ID of the AP that sends LAU message is sent to location-server, and location-server is stored in table 2 with this corresponding relation:

IMSI	AP?ID
		IMSI1	APID1
IMSI2	APID1
		...	...

Table 2

Because UE can move between different AP, therefore, the corresponding relation of the IMSI of UE and the ID of UE place AP can respective change, therefore, can only preserve IMSI and the corresponding relation that UE belongs to the ID of AP of the UE of up-to-date acquisition in the table 2.

Need to prove here; AG can obtain the corresponding MSISDN of this IMSI from equipment of the core network according to the IMSI of UE; Can also obtain SAI or the Cell ID of AP according to the ID of the resident AP of UE from equipment of the core network; Therefore, table 2 can comprise the corresponding relation of ID, SAI or Cell ID of IMSI or MSISDN and the AP of UE.It is understandable that, also can be preset at the IMSI of UE and MSISDN corresponding relation among the AG that AG can be according to the IMSI of UE from self obtaining the corresponding MSISDN of this IMSI.
