WAP gateway can be determined according to the URL in the WAP access request message SP of the required access of portable terminal, and then WAP gateway can authenticate the authority of this SP, judges whether this SP has the positional information of this portable terminal of authority acquiring.

Step 303, WAP gateway are determined the IP address information of this portable terminal according to the WAP access request message, and obtain corresponding mobile terminal identification according to this IP address information;

Present embodiment can suppose that the mobile terminal identification that WAP gateway gets access to is " 8611012345678 ".

Step 304, WAP gateway obtain corresponding positional information according to this mobile terminal identification;

WAP gateway within it section is safeguarded a terminal positional information administration module, stored the current positional information of online portable terminal in this terminal positional information administration module, when WAP gateway receives the WAP access request message of portable terminal transmission, can in the terminal positional information administration module, search according to the mobile terminal identification of obtaining the positional information of corresponding portable terminal, if found, then WAP gateway can obtain the positional information of the portable terminal corresponding with mobile terminal identification of local storage; If do not find, then WAP gateway can obtain by location gateway such as GMLC the positional information of the portable terminal corresponding with mobile terminal identification.

Step 305, WAP gateway add this positional information " x-huawei-location " in the protocol header extended field of this WAP access request message;

Because the agreement of this WAP access request message of carrying can be HTML (Hypertext Markup Language) (HypertextTransfer Protocol, hereinafter to be referred as: HTTP), also can be WAP, therefore this positional information " x-huawei-location " both can be stored in the protocol header extended field of WAP, also can be stored in the protocol header extended field of HTTP.

The positional information " x-huawei-location " of carrying in the protocol header extended field of this http protocol or wap protocol can comprise following daughter element:

x-huawei-location-cellid＝″″，x-huawei-location-position-X＝″″，x-huawei-location-position-Y＝″″，x-huawei-location-position-Z＝″″

Do not enter a new line between these four daughter elements, adopt CSV.

Wherein, x-huawei-location-cellid=" " represents the cellular cell sign of this portable terminal, the i.e. current residing cellular cell of this portable terminal " cellid " and area code " areanum ", the form of x-huawei-location-cellid=" " can for " cellid; Areanum ".For example, " 35; 755 " expression " cellid " is 35, and " areanum " is 755; " 36; " expression " cellid " is 36, do not carry " areanum "; "; 755 " " cellid " do not carried in expression, and " areanum " is 755; X-huawei-location-position-X=" " represents the latitude information of portable terminal current location, for example, and x-huawei-location-position-X=" 40 07 24.240N "; X-huawei-location-position-Y=" " represents the longitude information of portable terminal current location, for example, and x-huawei-location-position-Y=" 1230724.240E "; X-huawei-location-position-Z=" " represents the elevation information of portable terminal current location.

The positional information that present embodiment can be established this portable terminal is:

x-huawei-location:location

x-huawei-location-cellid＝″36；″，x-huawei-location-position-X＝″4007

24.240N″，x-huawei-location-position-Y＝″123?07?24.240E″，

x-huawei-location-position-Z＝″″

Need to prove, because the step 302 of present embodiment hypothesis is to the authentication success of SP, therefore, the positional information of having carried portable terminal in the WAP access request message that WAP gateway sends to SP, for step 302 concerning the unsuccessful situation of the authentication of SP, WAP gateway does not just carry portable terminal in the WAP access request message that sends to SP positional information, namely above-mentioned positional information is empty.

The WAP access request message that step 306, WAP gateway send to the SP transmitting mobile terminal of correspondence;

Owing to all exist some can self-defining extended field in http protocol and the wap protocol, these extended fields are used for finishing special function, therefore, WAP gateway can be carried in positional information " x-huawei-location " in the protocol header extended field of the HTTP of WAP access request message or WAP, and this WAP access request message is sent to corresponding SP.Following daughter element can realize that namely the WAP access request message that WAP gateway will carry positional information " x-huawei-location " sends to corresponding SP:

So far, portable terminal can obtain the business information of SP feedback, finishes this Operational Visit operation.

In the present embodiment, WAP gateway is in the process of mobile terminal accessing SP, can know according to the WAP access request message that portable terminal sends the positional information of portable terminal, and by sending this WAP access request message to corresponding SP in the protocol header extended field that this positional information is included in the WAP access request message, thereby make SP know the positional information of portable terminal, reach the purpose that portable terminal is positioned.This process implementation is simple, and WAP gateway only needs to use the protocol header extended field of WAP access request message positional information can be carried in the WAP access request message.In this position fixing process, SP itself does not need to be undertaken alternately by any interface and WAP gateway, and the interface encoding and decoding that do not need to carry out various complexity are processed, therefore, the method of present embodiment has reduced the complexity of SP operation, has also alleviated the burden of SP place server simultaneously.And because SP can get access to by WAP gateway the positional information of portable terminal, so SP can provide related service for positional information according to the positional information that gets access to, and further expanded the scope of business of SP.Obtain at WAP gateway before the positional information of portable terminal, WAP gateway also will authenticate requested SP according to this WAP access request message, only have in the situation of the authority of obtaining this portable terminal at this SP of authentication and just obtain corresponding positional information, guarantee the fail safe of location information of mobile terminal with this.

Fig. 4 is the flow chart of sending method the 4th embodiment of location information of mobile terminal of the present invention, and as shown in Figure 4, the method for present embodiment comprises:

The WAP Push request message that step 401, reception SP send, this WAP Push request message carry mobile terminal identification and the position requests sign of portable terminal;

This WAP Push request message can be used for SP and come sending business information to portable terminal transmission PUSH message.SP is in order to position the portable terminal corresponding with the WAP Push request message, can carry the position requests sign in the WAP Push request message that sends, WAP gateway can know that SP needs WAP gateway to feed back the positional information of corresponding portable terminal when receiving the WAP Push request message that carries the position requests sign.For instance, this mobile terminal identification and position requests sign can be stored in the WAP Push request message the propelling movement access protocal (Push Access Protocol, hereinafter to be referred as: in protocol header extended field PAP).

Step 402, obtain the positional information of portable terminal according to this mobile terminal identification;

WAP gateway can adopt dual mode when obtaining the positional information of the portable terminal corresponding with this mobile terminal identification: the positional information of obtaining the portable terminal corresponding with mobile terminal identification of local storage; Or obtain the positional information of the portable terminal corresponding with mobile terminal identification by the location gateway.

Specifically, WAP gateway within it section is safeguarded a terminal positional information administration module, stored the current positional information of online portable terminal in this terminal positional information administration module, when WAP gateway receives the WAP Push request message of SP transmission, can in the terminal positional information administration module, search according to the mobile terminal identification of carrying in this WAP Push request message the positional information of corresponding portable terminal, if found, then WAP gateway can obtain the positional information of the portable terminal corresponding with mobile terminal identification of local storage; If do not find, then WAP gateway can obtain by location gateway such as GMLC the positional information of the portable terminal corresponding with mobile terminal identification.

WAP gateway can obtain positional information with memory mobile terminal by following several modes:

Aaa server sends to WAP gateway with the cellular cell identification information of portable terminal and stores when sending the RADIUS on-line message;

WAP gateway is preserved the positional information of the mobile terminal reporting that has possessed the GPS function voluntarily.

Step 403, according to position requests sign, send the WAP Push request message to portable terminal;

WAP gateway can determine whether to push the WAP Push request message that SP sends to portable terminal according to the position requests sign.When specific implementation, can in the request mark of position, carry an indication information, for example use indication information " true " representative to issue the WAP Push request message to portable terminal, at this moment, WAP gateway not only will send the response message corresponding with the WAP Push request message to SP, also will send the WAP Push request message to portable terminal; Do not need to issue the WAP Push request message to portable terminal with indication information " false " representative, the positional information that this moment, WAP gateway only needed to feed back corresponding portable terminal to SP gets final product.

Need to prove that step 402 and step 403 can not have sequencing when carrying out.

Step 404, WAP gateway send the response message of this WAP Push request message to SP, and this response message comprises this positional information;

WAP gateway is when sending the response message corresponding with the WAP Push request message to SP, and the positional information of the portable terminal that WAP gateway can be got access to is carried in this response message, thereby makes SP can get access to the positional information of this portable terminal.For instance, the agreement of carrying this response message also can be the PAP agreement, and then this positional information also can be stored in the protocol header extended field of PAP of this response message.

Present embodiment obtains before the positional information of the portable terminal corresponding with mobile terminal identification at WAP gateway, can further include the step that WAP gateway authenticates the SP that asks the feedback location information of mobile terminal according to the WAP Push request message that receives.This verification process can judge whether the SP of request feedback location information of mobile terminal has authority to know the positional information of this portable terminal.If WAP gateway according to the WAP Push request message to the SP authentification failure, the positional information that then WAP gateway sends to SP in the step 403 is empty, namely when SP does not have authority to know the positional information of portable terminal, WAP gateway does not carry the positional information of this portable terminal in the response message of SP transmission, thereby has guaranteed the fail safe of location information of mobile terminal.

In the present embodiment, after the mobile terminal identification that WAP gateway carries in the WAP Push request message that receives the SP transmission, both can obtain the positional information of the portable terminal corresponding with this mobile terminal identification of local storage, also can locate the positional information that gateway obtains the portable terminal corresponding with this mobile terminal identification by other, and the positional information that gets access to fed back to SP, thereby realize that SP is to the location of portable terminal.This process implementation is simple, WAP gateway only needs to use the protocol header extended field of WAP Push request message the position requests sign can be carried in the WAP Push request message, only need to use the protocol header extended field of the response message that feeds back to SP the positional information of obtaining can be carried in the response message, thus the feedback of the request of completing place information and positional information easily.In position fixing process, SP itself does not need to be undertaken alternately by any interface and WAP gateway, and the interface encoding and decoding that do not need to carry out various complexity are processed, therefore, the method of present embodiment has reduced the complexity of SP operation, has also alleviated the burden of SP place server simultaneously.And because SP can get access to by WAP gateway the positional information of portable terminal, so SP can provide related service for positional information according to the positional information that gets access to, and further expanded the scope of business of SP.Obtain at WAP gateway before the positional information of portable terminal, WAP gateway can also authenticate SP according to this WAP Push request message, only have in the situation of the authority of obtaining this portable terminal at this SP of authentication and just corresponding positional information is fed back to SP, guarantee the fail safe of location information of mobile terminal with this.WAP gateway can also judge whether to issue the WAP Push request message to portable terminal according to position requests sign, thereby so that WAP gateway is more flexible to the mode that portable terminal pushes the business information that SP issues.
