Abstract
The key points of the method include following procedures: response message of position request returned from SLP to target SET contains indication information of returned positioning result; after receiving response of position request from SLP, and determining indication of returned positioning result in the response, target SET returns positioning result back to SLP. Using the invention makes SLP obtain final positioned result under condition of positioned SET-Based. Thus, the invention prevents that charging record of SLP still considers it is a successful positioning operation even if positioning operation by SET is failed so that SLP can take different charging strategy based on whether user obtains positioned result. Moreover, SLP can pass the positioned result to third party. SLP can buffer the positioned result of the target SET. Thus, in subsequent, possible other positioning the target terminal, the positioning result of satisfying QoS of positioning request can be provided rapidly.
Description
Technical field
The present invention relates to the business field, shift position, be meant especially and a kind ofly obtain the method for positioning result based on safe user plane location (SUPL, Secure User Plane Location) locating platform.
Background technology
Roughly process is following for current localization method based on safety: when a client through resident Location based service (MLS above that; When Mobile Location Services) use initiating location to a target terminal; SUPL locating platform (SLP, SUPL Location Platform) notification target terminal begins the location, through the accurate location sessions of target terminal and SLP; Completion is to target terminal position calculation; Notify MLS client by SLP with result of calculation, accomplish whole position fixing process, such flow process belongs to network originated instant positioning flow; Corresponding therewith; When SUPL terminal (SET, SUPL EnabledTerminal) initiates oneself location, carry out interacting message between SET and SLP; And finally through obtaining oneself position with the accurate location sessions of SLP, this flow process belongs to the instant positioning flow that mobile phone starts.
Above-mentioned SLP with terminal execution positioning action is the ownership SLP (H-SLP, Home SLP) at this terminal or visits SLP (V-SLP, Visit SLP).But the still H-SLP that receives Location Request and whole position fixing process is controlled.
The schematic flow sheet of location immediately for existing typical initial terminal shown in Figure 1.Hypothetical target SET does not roam in this flow process, and is agency's (proxy) pattern.
Step 101 after being positioned at SUPL agency (SUPL Agent) on the target SET (Target SET) and receiving the application location request initiating that operates on the SET, is set up data and is connected.Concrete, if Target SET is also online attached to grouped data, then Target SET adheres to up oneself, perhaps Target SET will set up a circuit switched data connection.
Step 103, after H-SLP test-target SET does not carry out the SUPL roaming, execution in step 104.
Step 104, H-SLP returns SUPL Location Request response message (SUPLRESPONSE) immediately to Target SET.The parameter that comprises indication locate mode (posmethod) among the SUPL RESPONSE is the posmethod parameter.
In accurate position fixing process, the concrete message content that carries in the SUPL POS message can be based on RRLP, RRC and TIA-801 protocol message.
If locate mode based on terminal auxiliary (SET-Assisted); Then H-SLP is according to the location measurement information calculating location estimated result of receiving; If based on the locate mode of terminal (SET-Based), then the auxiliary data that provides according to SLP of Target SET calculates the location estimation result.
In addition, except the location immediately of initial terminal, also have a kind of triggered location of initial terminal, referring to Fig. 2, shown in Figure 2 is the schematic flow sheet of the triggered location of existing typical initial terminal.Same hypothetical target SET does not roam in this flow process, and is agency's (proxy) pattern.
Step 201, be positioned at the triggered location request that SUPL Agent on the Target SET receives that the application that operates on the SET initiates after, set up data and connect.Concrete, if Target SET is also online attached to grouped data, then Target SET will adhere to up oneself, perhaps Target SET sets up a circuit switched data connection.
Step 203, after H-SLP confirms that target SET is roamed, execution in step 204.
Step 209, if SET need carry out when locating next time, repeated execution of steps 205 to 208.
Accurate position fixing process among the SUPL is to carry concrete location protocol by SUPL POS to realize at present.The structure of SUPL POS message is as shown in table 1:
| Parameter (Parameter) | There is (Presence) | Describe (Description) |
| Location load (Positioning Payload) | Necessary (M) | This parameter is based on TIA-801, the message of RRLP or RRC agreement |
| Speed (Velocity) | Inessential (O) | The speed of SET need be greater than information default in RRLP and RRC.In [3GPP GAD], define |
Table 1
The agreement of being carried among the SUPL POS is different, and concrete localization message is also inequality, and the situation of carrying RRLP, RRC or TIA-801 among the SUPL POS is described respectively below.
Shown in Figure 3 is the message flow chart of carrying RRLP among the existing SUPL POS.
Step 301, SLP is used for positioning assistance data is sent to target SET through auxiliary data (Assistance Data) message content of SUPL POS message bearing based on the RRLP agreement.
Step 302, SET receives after the complete auxiliary data to return based on the auxiliary data of RRLP to SLP and replys (Assistance Data Ack), and this is replied and is carried on SUPL POS message, and expression receives the data success.
Shown in Figure 4 is message flow chart when carrying RRC among the existing SUPL POS.
Step 401, SLP transmits (Assistance Data Delivery) message content through the auxiliary data in the SUPL POS message bearing RRC agreement, and positioning assistance data is sent to target SET.
Shown in Figure 5 is message flow chart when carrying TIA-801 among the existing SUPL POS.
Step 501, location survey data (the Position Determination Data) message that SLP sends among the SUPL POS message bearing TIA-801 is sent auxiliary data to target SET.
Using the SET-Based localization method and be that SET starts under the situation of location; SET can calculate positioning result voluntarily according to the positioning assistance data that SLP sends over, and SLP only works to provide auxiliary data in the prior art at this moment, it is thus clear that locate at initial terminal; Use under the situation of SET Based localization method; Prior art has been ignored the demand that SLP need obtain final positioning result, causes SLP can not know but after positioning service is provided whether the user has really obtained positioning result, like this; Under the situation of SET location failure, think still but in the station message recording of SLP that this is the positioning action of a success.
And prior art is not considered need positioning result be sent to third-party situation under the situation of initial terminal location yet.

Embodiment
Below in conjunction with accompanying drawing the present invention is explained further details again.
Core of the present invention is: SLP increases restoring to normal position result's indication information in the Location Request response message that returns to target SET; Target SET receives the Location Request response from SLP; Confirm to comprise in this response restoring to normal position result's indication; After calculating positioning result, this positioning result is returned to SLP, thereby make and locate at initial terminal; Use under the situation of SET Based localization method, SLP has obtained positioning result.Positioning result wherein can be an actual position information, also can be the information of location success or failure, if the location failure information then also comprises failure reason value in this information.
Concrete: the method that in the Location Request response message, increases restoring to normal position result's indication information is: set up a parameter field Loc Estimates at the Location Request response message; Whether value through this field indicates the restoring to normal position result; For example the value of this parameter is TRUE; Then showing needs target SET restoring to normal position result, if the value of this parameter is FALSE, then showing does not need target SET restoring to normal position result.Like this, the field that whether value of Loc Estimates parameter indicates the restoring to normal position result in the Location Request response message that target SET receives through judgement need to determine whether the restoring to normal position result.Definition about Loc Estimates parameter is as shown in table 2:
| Parameter (Parameter) | There is (Presence) | Describe (Description) |
| Loc?Estimates | Option (CV) | Whether sign SLP need obtain the final positioning result of target SET. |
Table 2
If positioning flow is the positioning flow immediately of initial terminal, then above-mentioned Location Request response message is a SUPL RESPONSE message; If positioning flow is the triggered location flow process of initial terminal, then above-mentioned Location Request response message is a SUPL TRIGGERED RESPONSE message.
Before the Location Request response message that SLP returns to target SET, SLP judges whether needs target SET restoring to normal position result according to the configuration information of systemic presupposition; Perhaps, whether needs sent positioning result to third party after SLP finished according to the location judges whether needs target SET restoring to normal position result.According to this judged result, the value that the SLP decision is inserted in Loc Estimates parameter.
Can take multiple implementation when target SET gives the SLP restoring to normal position as a result, below be that example describes with three kinds of implementations.And all hypothetical target SET is definite in following all realizations will give SLP restoring to normal position result.
Implementation one: give SLP restoring to normal position result in the message content that in accurate localization message (SUPL POS), is carried.Because the message of being carried among the SUPL POS is different, thereby its realization flow is also just different, and the situation of just carrying RRLP, RRC and TIA-801 is below explained respectively.
If carry message among the SUPL POS based on RRLP, then target SET give SLP restoring to normal position result process referring to Fig. 6, shown in Figure 6 for using the schematic flow sheet based on the SUPL POS message of RRLP of implementation one of the present invention.
Step 601, SLP sends the SUPL POS message based on RRLP to target SET, comprises auxiliary data (Assistance Data) message content based on RRLP in this SUPLPOS message.
Step 602, target SET are returned to SLP and are comprised the SUPL POS message that auxiliary data is replied (Assistance DataACK) message content, successfully receive data to show.
Need to give SLP restoring to normal position result because target SET has known, therefore, after target SET receives Assistance DataACK message, also can continue to receive subsequent message.
Step 603, SLP is through measurement and positioning request (the Measure Position Request) message content in the SUPL POS message bearing RRLP agreement, and indicating is request position calculation result.
Step 604 after target SET calculates positioning result, is returned the SUPL POS message that comprises measurement and positioning response (Measure Position Response) message content to SLP, and wherein positioning result is included among the Measure Position Response.
In practical application; If auxiliary data is few; Or not strict to the reliability requirement of auxiliary data, also 601,602 liang of steps of execution in step not, and 603,604 liang of steps of execution in step only; Like this, the needed auxiliary data of target SET is fallen through the Measure Position Request in the step 603 and is obtained.
If carry message among the SUPL POS based on RRC, then target SET give SLP restoring to normal position result process referring to Fig. 7, shown in Figure 7 for using the schematic flow sheet based on the SUPLPOS message of RRC of implementation one of the present invention.
Step 701, SLP sends to target SET and comprises the SUPL POS message of measuring control (Measurement Control) message content, transmitting auxiliary data to target SET, and request set result.
Step 702 after target SET calculates positioning result, is returned the SUPL POS message that comprises measurement report (Measurement Report) message content to SLP, and wherein positioning result is included among the Measurement Report.
Because having known, target SET needs to give SLP restoring to normal position result; Therefore; Target SET must be waited for SUPL POS (RRC (Measurement Control)) message; Need not give SLP restoring to normal position result if target SET has known, target SET is waited for treatment S UPL POS (RRC (AssistanceData Delivery)) message.
If carry message among the SUPL POS based on TIA-801, then target SET give SLP restoring to normal position result process referring to Fig. 8, shown in Figure 8 for using the schematic flow sheet based on the SUPL POS message of TIA-801 of implementation one of the present invention.
Step 802 after target SET calculates positioning result, is returned the SUPL POS message that comprises location survey data (Position Determination Data) message content to SLP, and wherein positioning result is included among the Position Determination Data.
Implementation two: accurately setting up the field that is used to indicate positioning result among the localization message SUPL POS; With positioning result place accurate localization message SUPL POS preset be used to indicate in the field of positioning result, give SLP restoring to normal position result through SUPL POS.
If carry message among the SUPL POS based on RRLP, then target SET give SLP restoring to normal position result process referring to Fig. 9, shown in Figure 9 for using the schematic flow sheet based on the SUPL POS message of RRLP of implementation two of the present invention.
If carry message among the SUPL POS based on RRC, then target SET give SLP restoring to normal position result process referring to Figure 10, shown in Figure 10 for using the schematic flow sheet based on the SUPL POS message of RRC of implementation two of the present invention.
Step 1001, SLP sends to target SET and comprises the SUPL POS message that auxiliary data transmits (Assistance DataDeliverry) message content, to transmit auxiliary data to target SET.
Step 1002 after target SET calculates positioning result, places this positioning result in the preset position field of SUPL POS message, returns SUPL POS message to SLP, and wherein positioning result is included in the position field in the SUPL POS message.The form of this SUPL POS message can be SUPL POS (position) or SUPL POS (RRC (), position).
Implementation three: change the sending direction of location end, send the location end to SLP, comprise positioning result in this message by target SET.
Referring to Figure 11, it is the sketch map of positioning flow immediately of using the initial terminal of implementation three of the present invention.
Step 1101～1103, it is identical with step 101～103 among Fig. 1, is specially: after being positioned at SUPL Agent on the target SET and receiving the application location request initiating that operates on the SET, set up data and connect.Set up safe IP between SUPL Agent and the SLP and be connected, and send that SUPL START is used to begin and SLP between location sessions.This SUPL START message has comprised session-id, SET capabilities and lid.SLP test-target SET does not carry out SUPL roaming, execution in step 1104.
Step 1104, SLP returns SUPL RESPONSE to Target SET, comprises indication locate mode posmethod parameter in this message, and the Loc Estimates parameter that indicates whether the restoring to normal position result.
In accurate position fixing process, the concrete message content that carries in the SUPL POS message can be based on RRLP, RRC and TIA-801 protocol message.
Referring to Figure 12, it is a triggered location schematic flow sheet of using the initial terminal of implementation three of the present invention.
Step 1201～1203, step 201～203 among itself and Fig. 2 are identical, are specially: after being positioned at the triggered location request that SUPL Agent on the Target SET receives that the application that operates on the SET initiates, setting up data and connect.Target SET is set up IP with SLP and is connected, and sends SUPLTRIGGERED START to SLP, comprises session-id in this message, SET ability, station location marker and area triggering positioning task.SLP confirm target SET roam the back execution in step 1204.
Step 1204; SLP returns SUPL TRIGGERED RESPONSE to target SET; This message has comprised the sign reqid or the sessionid of unique this triggered location of indication, and definite localization method also comprises the Loc Estimates parameter that indicates whether the restoring to normal position result.
Step 1205, identical with the step 206 among Fig. 2.Be specially: when SET need begin to locate, initiate SUPLPOS INIT message, the location sessions between beginning and the SLP to SLP.
Step 1206, it is mutual to carry out SUPL POS between SET and the SLP.
Step 1207, SET sends SUPL REPORT to SLP, and positioning result is notified to SLP, finishes current location sessions.This positioning result is included among the SUPL REPORT.
Step 1208～1210, identical with step 208～210 among Fig. 2, be specially: if the cycle triggered location, target SET reports the triggered location report to SUPL Agent.If area triggering positioning, when area trigger event took place, target SET reported the triggered location report to SUPL Agent, and the report triggering incident takes place.If SET need carry out when locating next time, repeated execution of steps 1205 to 1208.During the triggered location task termination, SET returns SUPL END message to SLP, finishes whole triggered location session.SLP is connected with the SET release IP, and discharges all resources relevant with this triggering task.
That is to say that when positioning flow was the positioning flow immediately of initial terminal, former cause SLP sent to the SUPL END message of target SET, changes into by target SET and sends to SLP.When positioning flow was the triggered location flow process of initial terminal, former cause SLP sent to the SUPLREPORT message of target SET, changes into by target SET and sends to SLP.
Use the present invention, which kind of implementation no matter if Target SET hopes positioning result is sent to the third party, then also comprises in the target SET institute location request initiating message positioning result is sent to third-party indication, and third-party sign.Like this, after SLP has obtained positioning result, will further send the positioning result that receives to third party according to fixed third-party sign.If positioning flow is a positioning flow immediately, then above-mentioned locating request message is SUPL START; If positioning flow is to trigger flow process, then above-mentioned locating request message is SUPL TRIGGERED START.Certainly; Requiring to notify under the third-party situation; SET institute location request initiating message is not limited to this; Can positioning result be sent to third-party indication through increasing in existing any SET location request initiating message, and third-party label manner is indicated positioning result is sent to the third party.In addition, the positioning result that SLP can the buffer memory target SET in the location to this target terminal of follow-up possible other, can provide the positioning result that satisfies Location Request Qos fast.
In above-mentioned three kinds of implementations, all be to be that example describes with the situation that target SET is not roamed.If target SET is in roaming state, then can know according to existing standard, can be by positioning operation between H-SLP or V-SLP and the target SET.If by positioning operation between H-SLP and the target SET, then target SET directly returns to H-SLP with last positioning result, by H-SLP positioning result is notified to the third party; If by positioning operation between V-SLP and the target SET; Then the interactive operation in early stage remains and carries out between target SET and the H-SLP; Just when positioning operation, carry out between just by V-SLP and target SET; And V-SLP can return to H-SLP with last positioning result, and is same, notifies the third party by H-SLP with positioning result.
The flow process of triggered location described in the present invention can be a cycle triggered location flow process, also can be the area triggering positioning flow process.
