Below in conjunction with the accompanying drawings and specific embodiment the present invention is further described in more detail.

Fig. 7 is the flow chart for the SUPL that the present invention is provided, as shown in fig. 7, it is comprised the following steps that：

Step 701：The H-SLP of target SET ownership is received after the locating request message to target SET that SUPL agent is sent, and target SET is positioned, positioning is finished, is obtained target SET positional informations.

If the Location Request to target SET is self-positioning requests of the target SET by the SUPL agent initiation positioned at itself, locating request message only carries target SET marks；If being Location Request of the initiator's client initiated of the network side SUPL agent associated with H-SLP to target SET to target SET Location Request, locating request message carries target SET marks and initiator's client identification.

Step 702:H-SLP judges whether to get third party's client-side information, if so, performing step 703;Otherwise, this flow terminates.

Third party's client-side information includes：Third party's client identification, business information of third party's client registers etc..

H-SLP can get third party's client-side information by following approach：

Approach one, in the locating request message to target SET get third party's client-side information； Third party's client-side information can be carried in locating request message, for the SUPL flows originated to SET, locating request message refers to that SUPL starts message, for network originated SUPL flows, locating request message refers to MLP SLIR message.

Approach two, in the H-SLP that target SET and/or initiator's client the belong to target SET preserved and/or the log-on message of initiator's client find third party's client-side information；

Target SET and/or initiator's client can register third party's client-side information when being registered to the H-SLP of own home, and then third party's client-side information correspondence is stored in the log-on message of target SET and/or initiator's client by H-SLP.

Approach three, from privacy check entity（PCE, Privacy Checking Entity) third party's client-side information is found in the privacy information that reports of the target SET that gets and/or initiator's client.

Target SET and/or initiator's client can report third party's client-side information in registration location business to PCE, and then third party's client-side information correspondence is stored in the privacy information of target SET and/or initiator's client by PCE.

The positioning service type information that approach four, the Location Request sent according to SUPL agent are carried, and the corresponding relation of the positioning service type information itself preserved and third party's client-side information get third party's client-side information.

H-SLP pre-saves the corresponding relation of positioning service type information and third party's client-side information, when SUPL agent sends Location Request to H-SLP, target SET positioning service type information is carried in the Location Request, H-SLP is received after the Location Request, the positioning service type information carried according to the Location Request, in corresponding relation of the positioning service type information that itself is preserved with third party's client-side information, third party's client-side information is found.

It is pointed out that H- from target SET to own home SLP or PCE when reporting third party's client-side information, the information that third party's client can be reported whether to need target SET to carry out Notification Validation simultaneously.In network originated SUPL flows, if the third party visitor that H-SLP is obtained Family client information includes the information for needing target SET to carry out Notification Validation, then H-SLP to third party's client before target SET positional informations are sent, need first to send the Notification Validation request message for carrying third party's client identification to target SET, after the Notification Validation response message for third party's client identification that the carrying for receiving target SET returns allows to notify, the corresponding third party's client of third party's client identification notified is allowed to send target SET positional informations to this.Specifically, after the notified confirmation request message of target SET, the third party's client identification that the Notification Validation request message can be carried is shown to user, so that user selects to allow third party's client identification of notice, after user is selected, the third party's client identification for allowing to notify that user is selected is sent to H-SLP by Notification Validation response message.

Here, third party's client is probably one, it is also possible to more than one.

Step 703:Target SET positional informations are sent to third party's client by H-SLP.

In actual applications, target SET positional informations are carried in position informing message, and the position informing message also carries target SET ID simultaneously.

Position informing message can be carried by wap push or SMS triggering modes.

Based on safety, H-SLP can also carry key identification and MAC in the notification message of position, and third party's client receives after the position informing message, the key and MAC are verified, if being verified, and receive the position informing message；If checking does not pass through, ignore the position informing message.

If third party's client is more than one, H-SLP sends position informing message to them simultaneously.Third party's client is received after position informing message, can not make any processing；Also it can represent to have had successfully received the position informing message to H-SLP home position push-notification-answer, meanwhile, third party's client Dry puts related resource.Specifically, SUPL agent can carry the information for whether requiring third party's client home position push-notification-answer in locating request message, H-SLP after obtaining target SET positional informations, target SET positional informations are sent to third party's client by position informing message before, judge whether locating request message that SUPL agent is sent carries and require third party client Hold home position push-notification-answer information, if, carry the information for requiring home position push-notification-answer simultaneously in the notification message of position, third party's client is received after position informing message, if detecting the message carries the information for requiring home position push-notification-answer, to H-SLP home position push-notification-answer message.

If H-SLP requires third party's client home position push-notification-answer, based on safety, before H-SLP sends position informing message, will according to as defined in SUPL agreements algorithm, calculate and preserve the Hash of the position informing message, third party's client is received after the position informing message, also according to algorithm as defined in SUPL agreements, calculate the Hash for obtaining the position informing message, then the Hash is carried and is sent to H-SLP in the verifying field parameter of position push-notification-answer message, H-SLP is received after the position informing response message, Hash in the position informing response message and the Hash itself preserved are matched, if the match is successful, then receive the position informing response message；If it fails to match, ignore the position informing response message.

Here, the security mechanism between H-SLP and third party's client uses security mechanism specified in SUPL agreements completely.In SUPL agreements, message code stream is calculated according to regulation algorithm, a Hash on the message can be obtained.Using the SUPL entities of the security mechanism, before sending some message or after receiving some message, algorithm is calculated the message according to specified in the security mechanism of SUPL agreements, so that it may obtain a Hash on the message.

In addition, H-SLP predeterminable one waits position informing response time, from being sent the position informing message moment to certain third party's client, if the duration is not crossed and confiscates the position informing response of third party's client, think that third party's client does not receive position informing message, then repeat and send the position informing message to third party's client；If duration mistake, but H-SLP still confiscates the position informing response of third party's client, then, H-SLP can identify the notice failure to third party's client in the position informing response message or SLIA message for being sent to SUPL agent.
