Description

Trigger positioning method based on zone issue

Technical field

The present invention relates to service technique field, shift position, be specifically related to a kind of trigger positioning method based on zone issue based on user plane.

Background technology

SUPL (secure user plane location) is a kind of standard agreement that adopts user plane, allow the communications protocol of the position of mobile phone user's and acquisition running fix terminal mutual with location-server.

General instant terminal positioning is divided into network originated location and initial terminal location: the initiator of a request location initiates the location of another one terminal is belonged to network originated location by its client; Initiation belongs to the initial terminal location to the location of oneself.Its process is respectively:

When the initiator's of a request location client is used the location of initiating the another one terminal by residing in its MLS (Location based service), the H-SLP of target terminal (ownership location-server) notification target terminal begins the location, session by target terminal and this H-SLP, finish target terminal position calculation, notify MLS client with result of calculation at last, finish position fixing process; Corresponding therewith, when the SUPL terminal is initiated own location, the H-SLP session of this terminal and its ownership, and the final position of acquisition immediately oneself.

And the triggered location process is different from above-mentioned instant position fixing process.When the MLS of client used triggered location initiating target terminal, the triggered location condition resided among the H-SLP or target terminal of target terminal.Periodically initiate position fixing process if trigger resides in H-SLP when going up by H-SLP, periodically initiate position fixing process by target terminal oneself if trigger resides on the target terminal to target terminal.When satisfying trigger condition, return the triggered location report by trigger place direction SUPL agency.

At present, the method that whether satisfies the area triggering condition at this two kinds of patterns (trigger is arranged in target terminal and trigger is positioned at network) lower area triggered location detection target terminal all is periodically to obtain target terminal position, by with Location Request in the target area of appointment compare and judge whether to meet trigger condition, if then report the area triggering positioning report to the SUPL agency.

For example, trigger be positioned at terminal network originated area triggering positioning flow process as shown in Figure 1:

In the starting stage, location-server is after receiving the area triggering positioning request that the SUPL agency initiates, the triggered location task is notified to target terminal (situation of network originated location, if the location of initial terminal, the triggered location task is at the very start on target terminal).At positioning stage, target terminal began periodically to initiate Location Request to location-server from time started of term of reference, by with location-server get access to the exact position result alternately after, the target area and the triggering type of preserving with this locality (enter, leave, in inside) compare, if satisfy trigger condition, then report area triggering positioning report (if the initial terminal location, then target terminal directly reports to the SUPL agency and triggers report) to the SUPL agency by location-server.

Trigger be positioned at network initial terminal area triggering positioning flow process as shown in Figure 2:

In the starting stage, location-server is kept at this locality with the area triggering positioning task after receiving the area triggering initiation message that target terminal is initiated.At positioning stage, begin periodically to initiate repeatedly positioning flow immediately according to the location tasks official hour to target terminal, each after getting access to the exact position of target terminal with the triggered location task in the target area and the area triggering type of appointment (enter, leave, in inside) compare, if satisfy trigger condition, then the notification target terminal is returned to the SUPL agency and is triggered report.

By above-mentioned flow process as seen, in the existing area triggering positioning flow process, when initiating the location by network, if trigger is positioned at end side and adopts the auxiliary localization method (SET-Assisted) of terminal, then location-server is after finishing target terminal position calculation, need to send position result and report to target terminal, judge whether to satisfy trigger condition by target terminal, and then judged result is reported to location-server by target terminal.Equally, when initiating the location by target terminal, when if trigger is positioned at network side and adopts the localization method (SET-Based) of network assistance, target terminal is after finishing its position calculation, need to send position result and report to location-server, judge whether to satisfy trigger condition by location-server, and then judged result is reported to target terminal by location-server.These two kinds of processes have in fact all adopted unnecessary reporting process, and like this, too much interacting message has not only greatly been wasted network and terminal resource, and has influenced location efficiency.

Embodiment

Core of the present invention is in the starting stage based on area triggering positioning, with judge whether target terminal enters the specific region, leave the specific region, trigger condition in inside, specific region is kept on location-server and the target terminal simultaneously.Like this, when the area triggering positioning request is initiated by network, if adopt the auxiliary localization method of terminal, then server is after finishing target terminal position calculation, just can judge whether to satisfy trigger condition, if satisfy then the direct SUPL agency who the result is reported to network terminal by location-server oneself.Equally, when the area triggering positioning request is initiated by terminal, if adopt the auxiliary localization method of terminal, location-server is after finishing target terminal position calculation, just can oneself judge whether to satisfy trigger condition by it, if satisfy then send SUPL REPORT message informing target terminal, trigger respective application; If when adopting the localization method of network assistance, target terminal oneself judges whether to satisfy trigger condition by it after finishing its position calculation, if satisfy then directly trigger application corresponding.

In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.

With reference to Fig. 3, Fig. 3 shows the realization flow of the inventive method, may further comprise the steps:

Step 301:, will judge that the area trigger event triggering condition is kept on location-server and the target terminal simultaneously in area triggering positioning initial stage.

For network originated area triggering positioning, SUPL sends MLP TLRR (running fix agreement trigger position report request) message to location-server, in this message, comprise client identification, target terminal identified areas triggered location task, i.e. information such as trigger event, location quality of service.Location-server obtains the trigger event in this message.

Area triggering positioning for initial terminal, after being positioned at SUPL agency on the target terminal and receiving the application location request initiating that operates on the terminal, target terminal sends SUPL TRIGGERED START message, the location sessions between beginning and the location-server to location-server.In this message, comprise session-id terminal capability and parameter informations such as station location marker, area trigger event.Location-server obtains the trigger event in this message.

Location-server generates zone issue according to the trigger event that obtains and triggers Rule of judgment, and it is kept at this locality.Specifically the target area can be converted to the corresponding relation of Target cell tabulation or other network identities and described target area.Location-server triggers Rule of judgment by SUPL TRIGGERED RESPONSE (secure user plane triggered response) message with zone issue and sends to target terminal after receiving the affirmation message of target terminal to the location notice.Then, by target terminal this area triggering condition is kept at its this locality.

Step 302: when adopting the auxiliary localization method of terminal, location-server oneself judges whether to satisfy trigger condition and triggering following positioning flow according to the area trigger event triggering condition of preserving after finishing target terminal position calculation.

The present technique field personnel know, when positioning calculating, can adopt by the auxiliary computational methods of terminal, that is to say by location-server and carry out the target terminal position calculation, also can adopt computational methods, that is to say by target terminal and carry out its position calculation based on terminal.Utilize the present invention, owing to will judge that in positioning initial stage the area trigger event triggering condition has been kept on location-server and the target terminal simultaneously.Therefore, just can decide at different computational methods by location-server still is to carry out trigger condition by target terminal to judge.

If what consult in the starting stage is the localization method that adopts terminal auxiliary, then location-server oneself judges whether to satisfy trigger condition according to the area trigger event triggering condition of its preservation after the position calculation of each execution cycle property.When satisfying trigger condition, for network originated area triggering positioning, location-server returns the triggered location report by MLP TLREP (report of running fix agreement trigger position) message to the SUPL agency, send SUPL END (finish the secure user plane location) message to target terminal simultaneously, finish current location sessions; For the area triggering positioning of initial terminal, location-server takes place to target terminal report area trigger event by SUPLREPORT message.After target terminal is received the SUPL REPORT message of location-server transmission, trigger, finish current location sessions to its inner SUPL proxy-reporting zone issue.

Step 303: when adopting the localization method that calculates based on terminal, target terminal oneself judges whether to satisfy trigger condition and triggering following positioning flow according to the area trigger event triggering condition of preserving after finishing its position calculation.

If the starting stage consult be based on the localization method that terminal is calculated, then target terminal oneself judges whether to satisfy trigger condition according to the area trigger event triggering condition of its preservation after the position calculation of each execution cycle property.When satisfying trigger condition, for network originated area triggering positioning, target terminal takes place to location-server report area trigger event; Location-server triggers to SUPL proxy-reporting zone issue after receiving the message of the zone issue generation that target terminal is reported, finishes current location sessions.For the area triggering positioning of initial terminal, target terminal triggers to its inner SUPL proxy-reporting zone issue, finishes current location sessions.

For network originated area triggering positioning, target terminal can take place to location-server report area trigger event by SUPL REPORT message.

In order further to reduce message interaction process, can expand existing SUPL POS message, expand a parameter and represent that trigger condition satisfies.

SUPL POS message after the expansion such as following table 1:

Table 1:

Parameter	There is option	Describe
Parameter	There is option	Describe	Positioning Payload	M	The TIA-801 of lower floor, RRLP or RRC member
Velocity	O	The speed of terminal	Positioning Payload	M	The TIA-801 of lower floor, RRLP or RRC member
Velocity	O	The speed of terminal	Trigger Condition Met	O	Very (Ture) or false (False) defaults to vacation (False)

Like this, when network is initiated Location Request, for the area triggering positioning of calculating based on terminal, after target terminal calculates the acquisition position result, just can utilize the SUPL POS message of expansion to transmit the report that trigger condition has been satisfied in the location, and need not to send again SUPL REPORT message.Thereby further reduced message interaction process, improved location efficiency.

Respectively the area triggering positioning flow process under the various triggering modes in the inventive method is described in further detail below.

1. also initiate the periodically pattern of location by server monitoring:

Location-server is decided through consultation positional parameter in the starting stage after receiving the area triggering request, determine under this pattern, whether begins periodically location by server monitoring.When server monitoring moves to when needing the pinpoint sub-district of beginning to terminal, server periodically issues SUPL TRIGGEREDINIT message to target terminal, is calculated the current location of (SET-Assisted) or target terminal calculating (SET-Based) target terminal by location-server by message subsequently.When adopting network location request initiating type, then judge whether to have satisfied trigger condition by location-server.If satisfy, then the notification target terminal stops reporting the SUPL agency when prelocalization and with the result; When adopting terminal location request initiating type, then judge whether to have satisfied trigger condition by target terminal oneself.If satisfy, then notify location-server to satisfy trigger condition, finish this location.

Among the present invention by network originated, server monitoring and initiate periodically positioned area triggered location flow process as shown in Figure 4:

A.SUPL Agent sends MLP TLRR (Triggered Location Reporting Request) message and gives H-SLP, has comprised client identification in the message, target terminal sign, area triggering positioning task (being information such as trigger event, QoP).

B.H-SLP carries out the privacy inspection, and judges whether target terminal is supported the SUPL area triggering positioning, whether roamed.If this client is uncommitted, then H-SLP directly returns MLPTLRA message to SUPL Agent, refuses this triggered location.

If c. this client is authorized to, H-SLP sends SUPL INIT message to target terminal, and this message can adopt SMS (short message) or WAP (wireless access protocol) carrying.This message comprised localization method, align_type (be locate immediately, cycle triggered location or area triggering positioning, or other location), QoP information such as (location quality of service).

D. the IP that sets up safety between target terminal and the H-SLP is connected.Target terminal can be notified to the relevant information of user's triggered location, if desired, also needs to obtain user's affirmation.If localization method, align_type, trigger mode that the user agrees this triggered location task and supports to indicate in the SUPL INIT message, then target terminal returns SUPL TREGGERED START message to H-SLP, comprises target terminal ability and the target terminal information such as result to the location Notification Validation in this message.

E.H-SLP returns MLP TLRA message to SUPL Agent, shows that this triggered location is identified.

F.H-SLP will be kept at this locality in the area trigger event that A obtained in the step, and return SUPL TRIGGERED RESPONSE message to target terminal, comprise relevant parameter, the area triggering condition of triggering task in this message, and the localization method of this subtask.The sign reqid (request mark) or the sessionid (session identification) that also comprise unique this triggered location of indication in this message.By SUPLTRIGGERED RESPONSE end of message triggered location initial phase.

G. when H-SLP need carry out locating the first time (the beginning to monitor when constantly arriving of triggered location task defined), if kept effective I P to be connected between H-SLP and the target terminal, then H-SLP can directly use this connection to issue SUPL TRIGGERED INIT message to target terminal, otherwise this message is by SMS or WAP PUSH carrying.The reqid or the sessionid that comprise this triggered location of unique identification in the message.

H. target terminal sends SUPL POS INIT message with the location sessions between beginning and the location-server to H-SLP.Comprised sessionid in the SUPL POS INIT message, terminal capability and terminal current position identification (lid).

I. position interacting message between target terminal and the H-SLP.Target terminal calculates self position (SET-Based mode) according to effective GPS (global positioning system) auxiliary data, and with position result and whether satisfy trigger condition and return to H-SLP.Perhaps, H-SLP calculates target terminal position (SET-Assisted mode) and judges whether to satisfy trigger condition according to the position measurement report of receiving.

J. when adopting SET Based localization method and not needing auxiliary data, SET calculates and also obtains after the position result and the area triggering condition of being preserved contrast, if satisfy then send SUPLREPORT message to server, the announcement server trigger condition is satisfied.

K. when the area triggering condition satisfied, H-SLP returned the triggered location report by MLP TLREP message to SUPL Agent, if require the home position result in the Location Request, then comprised the target terminal position estimated result in the report.

If l. H-SLP need carry out when locating, repeating step g to k next time.

M. when satisfying trigger condition, H-SLP returns SUPL END message to target terminal, finishes whole triggered location session.H-SLP discharges IP with target terminal and is connected, and discharges all resources relevant with this triggering task.

Initial terminal, by server monitoring and initiate periodically as shown in Figure 5 based on the positioning flow of area triggering:

A. the SUPL agency who is positioned on the target terminal receives the application location request initiating that operates on the terminal.Grouped data is online if target terminal also is not bundled in, and it is online then oneself to be tied to grouped data, perhaps sets up a circuit switched data by target terminal and connects.

B. the SUPL agency who is positioned on the target terminal uses the H-SLP default address that is disposed by home network, with set up safe IP between the H-SLP and be connected, and send that SUPL TRIGGERED START (secure user plane triggers and starts) message begins and location-server between location sessions.SUPLTRIGGERED START message has comprised session-id terminal capability and parameter informations such as station location marker, area trigger event.Terminal capability has comprised the localization method supported (SET-Asseisted A-GPS for example, SET-Based A-GPS) and corresponding location protocol (Radio Resource location protocol RRLP for example, radio resource control RRC, No. 801 agreement TIA-801 of American Communications industrial protocol).The localization method that the target terminal that comprises according to SUPLTRIGGERED START message is supported, H-SLP will be determined the localization method that adopts.If specified localization method, H-SLP will use in the SUPL TRIGGEREDSTART message with support location protocol (for example: RRLP, RRC, TIA-801).

C.H-SLP detects the current SUPL of the not carrying out roaming of target terminal.

D.H-SLP returns SUPL TRIGGERED RESPONSE message to target terminal, comprises parameters such as area triggering Rule of judgment that H-SLP generates according to zone issue, localization method in this message.Target terminal is kept at its this locality with the area triggering Rule of judgment in this message after receiving SUPL TRIGGERED RESPONSE message from H-SLP, and positioning initial stage finishes.

Because the mobility of target terminal, when target terminal is in roaming state, informational needs in the described zone position information tabulation obtains by the visit location-server of target terminal, and above-mentioned various area triggering positioning process needs are finished jointly by the H-SLP (ownership location-server) and the V-SLP (visit location-server) of target terminal.Under the situation that network is initiated, Client Agent is initiated Location Request to R-SLP (request location-server), R-SLP finds the ownership H-SLP of target terminal, whether H-SLP searches target terminal in roaming, if be in roaming state, then notify corresponding V-SLP, determine parameters such as localization method by the session negotiation between V-SLP, H-SLP and the target terminal, periodically check the current location of target terminal by trigger place side, when satisfying trigger condition, return the triggered location report to the SUPL agency.Finish whole position fixing process when locating periodically finishes or when satisfying area condition.Under the situation that terminal is initiated, terminal is initiated Location Request to its ownership SLP, H-SLP searches routing iinformation, if be in roaming state, then notify corresponding V-SLP, determine parameters such as localization method by the session negotiation between V-SLP, H-SLP and the target terminal,, when satisfying trigger condition, return the triggered location report to the SUPL agency by the current location that trigger place side periodically checks target terminal.Finish whole position fixing process when locating periodically finishes or when satisfying area condition.

Each position fixing process can be finished by H-SLP, also can be finished by V-SLP, and the description of specific implementation flow process and front is similar, does not repeat them here.

Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
