As shown in Figure 4, in the acquisition methods for the position information of user's terminal that relates in the embodiment of the present invention, the topological structure schematic diagram of wap data business networking.Wherein, core network element SGSN and GGSN adopt distributed great Qu deployment way processed in network-wide basis, only for the UE in certain regional area, providing data service access service, there is incidence relation with specific position in each SGSN disposing in network and GGSN.Routing mode during UE access WAP/HTTP business is: the GGSN that accesses this region by the SGSN of local (ownership place/roaming place) nearby, GGSN accesses corresponding WAP gateway according to WAP business domains attaching relation, then according to the object URL/IP address in visit data bag, accesses the service server of external data network by WAP gateway.Therefore,, if can know the positional information of GGSN, can identify by the positional information of GGSN the relevant information of geographical position of user terminal.

For the mobile PS territory network of 2G and 3G, the IP address assignment situation of core network element SGSN and GGSN is as follows:

SGSN:Gn interface assignment public ip address space;

GGSN:Gn interface assignment public ip address space;

Gi interface and external data network interconnection, distribute public ip address;

Each WAP gateway can be corresponding with a GGSN or a plurality of GGSN.

In prior art, when user terminal is asked access network by GGSN, need to activate the stage through PDPContext, in this stage, GGSN sends information as shown in table 2 below by RADIUS (Remote Authentication DialIn User Service, remote customer dialing authentication system) message Accounting Request (accounting request) to WAP gateway:

Table 2.RADIUS message field

Attribute definition	Describe
		User-Name	User name
User-Password	User cipher under pap authentication mode

CHAP-Password	User cipher under chap authentication mode
		NAS-IP-Address	The IP address of NAS equipment
NAS-Identifier	NAS sign
		Called-Station-Id	APN
Calling-Station-Id	Calling number
		CHAP-Challenge	CHAP challenging value

In the equipment of the core network in PS territory, by parameter configuration, can set the NAS in Accounting Request message (Network Access System network access system) IP address field " NAS-IP-Address " is transferred to WAP gateway as effective field.In WAP gateway, receive in the prior art after Accounting Request message, conventionally can ignore the NAS-IP-Address information in message, do not carry out any processing.Therefore in wap data business of the present invention networking, NAS is GGSN, can think that what in the NAS-IP-Address of RADIUS message field, carry is the IP address of GGSN.

In the WAP gateway providing in the embodiment of the present invention, according to the construction situation of operator's data core net and deployment planning, and each GGSN disposing in network and the incidence relation of geographical location information, store corresponding geographical location information data storehouse.In this geographical location information data storehouse, comprise the corresponding relation between all GGSNIP address and positional information, for example, use form as shown in table 3:
