Embodiment

The present invention typically implements in the SUPL network.Yet the present invention can also be applied to the wireless communication system according to the different specification operation.To describe with reference to preferred implementation of the present invention in detail now, in the accompanying drawings illustration its example.

The invention provides a kind of relevant triggered location service method of zone issue of in location information system, utilizing the counterpart terminal of user terminal requests expectation based on SUPL.For this reason, when the relevant triggered location of request zone issue is served, the user can be appointed as the zone of this zone issue the relevant specific region (certain area) of current location of terminal with it, or with the irrelevant concrete zone (specific area) of its terminal location.

Fig. 1 illustration according to the present invention first execution mode of request triggered location service method between the terminal in location information system.Specifically, this first execution mode has illustrated the method for checking the zone issue of SET2 in the specific region relevant with the current location of the SET1 that asks service.Here, SLP corresponding to network side SET corresponding to end side.

With reference to Fig. 1, the relevant request of receiving position from the application program of just among SET1, moving of the SUPL agency among the SET1.

When receiving the request of being correlated with the position,, then SET1 is connected to packet data network (S10) if the current data that are not established to arbitrary network connect.

If set up the data connection, then SET1 utilizes the default addresses for use that is provided by network to set up safe IP with location-server (SLP1) to be connected, and transmission session started message (SUPL START message) starts position measurement (location) session (S11) with SLP1.SUPL START message comprises session id, SET ability, location identifier (lid), msid, request type, defined range, event type etc.At this, it is the triggering service relevant with the position of SET1 that this request type is indicated this service request.This defined range indication has defined how wide zone from the position of SET1.The type of this event type indicating area incident (shift out, move into or maintain the original state).And this SET ability comprises supported localization method (for example the auxiliary A-GPS of SET-reaches the A-GPS based on SET) and relevant location protocol (for example, RRLP, RRC and TIA-801).And if the satisfied alignment quality (QoP) by the SET1 request in previous position of calculating, then SLP1 carries out next step (S16).

If the QoP of request is not satisfied in previous position of calculating, then SLP1 utilizes routing iinformation to determine that SET1 does not have roaming (its current coverage that belongs to) (S12), and determines the location-server SLP2 relevant with SET2 based on the msid that receives.

Thereafter, SLP1 determines a kind of suitable localization method, with the consistency of maintenance with the localization method that is included in the SET ability support in the SUPL START information of SET1.In determined localization method, SLP1 adopts the location protocol of being supported (being RRLP, RRC and TIA-801) that is included in the SUPL START message as required.After finishing these a series of operations, SLP1 to SET1 transmit comprise determined localization method conversational response message (SUPLRESPONSE message) (S13).SUPL RESPONSE message comprises session id, but does not comprise the address of SLP1, because SET1 does not need to set up new connection.

In addition, if the information that comprises in the SUPL START message (for example rough position result who is calculated by lid) satisfies the QoP of SET1 request, then SLP1 carries out next step (S16) immediately.

In response to the reception of SUPL RESPONSE message, SET1 then transmits location sessions to SLP1 and initiates message (SUPL POS INIT message) (S14).SUPL POS INIT message comprises session id, SET ability at least, reaches location identifier (lid).

When receiving SUPL POS INIT message, SLP1 is by exchanging the position (S15) that localization process message (SUPL POS message) is calculated SET1 with SET1 successively.In this case, measurement that has received from SET1 based on SLP1 (SET is auxiliary) or SET1 come calculating location from the auxiliary data (based on SET) that SLP1 obtains.

When the SUPL localization process finished between SLP1 and the SET1, SLP1 adopts RLP protocol message (RLP SSRLIR message) to trigger service (S16) to the SLP2 request as the location-server of SET2.RLP SSRLIR message comprises session id, msid, request type, defined range and event type.It is the triggering service relevant with the position of SET1 that this request type is indicated this service request.This defined range is indicated the calculating location of SET1 and is defined how wide zone from the position of this SET1.This which kind of zone issue of event type indicative of desired (whether this incident is for shifting out, move into or maintaining the original state).And if SLP2 has the mandate about the triggering service of SET1 request, then the SLP2 msid about SET1 that utilizes the client id that receives to authorize SET1 and utilization to receive comes user application security information (privacy).

When receiving RLP SSRLIR message, SLP2 utilizes the SET look-up table to check whether SET2 supports SUPL, and utilizes routing iinformation to check that SET2 is current whether to belong to coverage (whether SET2 roams) (S17).

According to the result who checks, when SET2 supported SUPL and do not roam, SLP2 utilized the location sessions of session initiation message (SUPL INIT message) initiation and SET2.SUPL INIT message comprises the COS of session id, proxy/non-proxy mode indicator, the localization method (posmethod) that will use and the service of indicating area Event triggered at least.In addition, SUPL INIT message can also comprise the QoP of expectation.

When receiving SUPL INIT message,, then SET2 is connected to packet data network (S19) if current foundation as yet is connected with the data of arbitrary network.Then SET2 sends session triggered start message (SUPL TRIGGERED START message) with the location sessions (S20) of startup with SLP2.SUPL TRIGGERED START message comprises session id, SET ability and location identifier (lid) at least.

If by be included in the SUPL TRIGGERED START message that receives information (for example, lid) the coarse localization result who calculates satisfies the QoP of SET2 request, and then SLP2 compares (S22) to this coarse localization result with the assigned address incident that receives from SLP1.

On the contrary, if this coarse localization result who calculates does not satisfy the QoP of SET2 request, then SLP2 transmits SUPL TRIGGERED RESPONSE message to SET2 and initiates triggering session (S21) with notice.SUPL TRIGGERED RESPONSE message comprises the localization method that will use in triggering session.

Subsequently, between SET2 and SLP2, periodically generate location sessions (S22).When each location sessions starts, between SET2 and SLP2, successfully exchange localization process message (SUPLPOS message).In this case, the auxiliary data (based on SET) that measurement that has received from SET2 based on SLP2 (SET is auxiliary) or SET2 have obtained from SLP2 is come calculating location.After finishing each location sessions, SLP2 compares with the assigned address that receives from SLP1 the position of the SET2 that calculates.According to relatively, if the position of the SET2 that calculates corresponding to the defined range that is provided with by SET1 and be the positional value that receives via SLP1, then SLP2 carries out next step, otherwise SLP2 repeats this step (S22).

If the position of the SET2 that calculates is corresponding to the defined range that is provided with by SET1 and be the position that receives by SLP1, then SLP2 stops location sessions (S23) by transmitting conversation end message (SUPLEND message) to SET2, then transmits the RLP SSRLIR message (S24) of the location comparison result value (POSRESULT) that comprises SET2 to SLP1.

Therefore, SLP1 transmits the SUPL END message (S25) of the location comparison result value (POSRESULT) comprise SET2 to SET1, so SET1 discharges all resources that safe IP connects and release is relevant with this session with SLP1.

Fig. 2 illustration according to the present invention second execution mode of request triggered location service method between the terminal in location information system.Second execution mode of the present invention is similar to first execution mode, and different is before transmitting RLP message to SLP2, has just stopped the connection between SLP1 and the SET1.That is, in the first embodiment, the IP connection between SLP1 and the SET1 is kept up to carrying out final step (S25), therefore causes the unnecessary waste of Radio Resource.Therefore, second execution mode of the present invention connects by sending the IP that SUPL END message stops between SLP1 and the SET1 from SLP1 to SET1 after the localization process between SLP1 and the SET1 is finished immediately.

Therefore, when the localization process of finishing between SLP1 and the SET1, SLP1 transmits the SUPL END message comprise session id to SET1 and finishes connection (S30) between SLP1 and the SET1, and then SLP1 triggers service by utilizing RLP protocol message (RLP SSRLIR message) to the location-server SLP2 of SET2 request.(therefore identical in S16～S24) and first execution mode omitted the detailed description to them to step subsequently.

When the triggering result (POSRESULT) of the expectation that receives SET2 from SLP2 (S24), SLP1 transmits this given triggering result (S31) via SUPL report message (SUPL REPORT message) to SET1.Trigger to wait via WAP PUSH, SMS and transmit this SUPL REPORT message.

Fig. 3 illustration according to the present invention the 3rd execution mode of request triggered location service method between the terminal in location information system.The 3rd execution mode has been to send SUPL END message with the second execution mode similarity and has been connected with the IP that stops between SET1 and the SLP1.Yet their difference is to transmit the time of SUPL END message.

That is, in second execution mode of the present invention, behind the position fixing process of finishing between SLP1 and the SET1, transmit SUPL END message immediately.In the 3rd execution mode of the present invention, only after will starting, the location sessions between SLP2 affirmation SLP2 and the SET2 just transmits SUPL END message.When SLP2 receives SUPL TRIGGERED START message and when SLP1 transmits RLPSSRLIR END message, this affirmation takes place from SET2.

Thereby when receiving SUPL TRIGGERED START message from SET2 and after RLP SSRLIR END message is transmitted to SLP1 (S40), SLP2 transmits SUPLTRIGGERED RESPONSE message to SET2, initiates triggering session (S41) with notice.For all those steps identical (S21～S24), omit detailed description to them with second execution mode.

After receiving RLP SSRLIR END message, SLP1 transmits SUPL END message to finish the connection (S41) between SET1 and the SLP1 to SET1.Subsequently, when receiving the triggering result (POSRESULT) of expectation from SLP2 (S24), SLP1 transmits given triggering result (S42) via SUPL RESPORT message to SET1.Trigger to wait via WAP PUSH, SMS and transmit SUPL RESPORT message.

Fig. 4 illustration according to the present invention the 4th execution mode of request triggered location service method between the terminal in location information system.Specifically, the 4th execution mode is a method of checking the zone issue of SET2 in the specific region that is provided with by SET1, and this method is not carried out the position fixing process between SET1 and the SLP1.

With reference to Fig. 4, the application program receiving position relevant request of the SUPL agency among the SET1 from just among SET1, moving.When receiving the relevant request in this position,, then SET1 is connected to packet data network (S50) if currently arbitrary network is not set up data as yet and connect.

In case set up the data connection, then SET1 utilizes the default addresses for use that is provided by network to set up safe IP with location-server (SLP1) to be connected, and transmission SUPL START message starts position measurement (location) session with SLP1.SUPL START message comprises: session id, SET ability, location identifier (lid), msid, request type, defined range, event type etc.At this, it is the triggering service relevant with particular location that this request type is indicated this service request.The concrete zone of defined range indication.This event type indication SET1 expects which kind of zone issue (shift out, move into or maintain the original state).Preferably, defined range comprises coordinate or zone name.

In addition, the SET ability comprises localization method (for example, the auxiliary A-GPS of SET-reaches the A-GPS based on SET) and the relevant location protocol (for example, RRLP, RRC and TIA-801) that can support.

When receiving SUPL START message, SLP1 utilize routing iinformation determine SET1 not roaming (its current coverage that belongs to) (S52) and determine the location-server (SLP2) relevant with target SET 2 based on the msid that receives.

SLP1 utilizes RLP protocol message (RLP SSRLIP message) to trigger service (S53) to the location-server SLP2 of SET2 request.RLP SSRLIP message comprises session id, msid, request type, defined range and event type.It is the triggering service relevant with ad-hoc location that this request type is indicated this service request.The concrete zone of defined range indication.Event type indication SET1 expects which kind of zone issue (shift out, move into or maintain the original state).If SLP2 has the mandate for the triggering service of SET1 request, then the SLP2 msid that utilizes the client id that receives to authorize SET1 and utilization to receive comes the user application security information.

After receiving RLP SSRLIR message, SLP2 utilizes the SET look-up table to check whether SET2 supports SUPL, and utilizes routing iinformation to check that SET2 is current whether to belong to coverage (whether it roams) (S54).

According to the result who is checked, if SET2 supports SUPL and not roaming, then SLP2 utilizes the location sessions (S55) of initiation of SUPL INIT message and SET2.SUPL INIT message comprises the COS of session id, proxy/non-proxy mode indicator, the localization method (posmethod) that will use and the service of indicating area Event triggered at least.In addition, SUPL INIT message can comprise the QoP of expectation.

When receiving SUPL INIT message,, then SET2 is connected to packet data network (S56) if current foundation as yet is connected with the data of arbitrary network.Then SET2 sends session triggered start message (SUPL TRIGGERED START message) with the location sessions (S57) of startup with SLP2.SUPL TRIGGERED START message comprises session id, SET ability and location identifier (lid) at least.

If by be included in the SUPL TRIGGERED START message that receives information (for example, lid) the coarse localization result who calculates satisfies the QoP of SET1 request, and then SET2 compares (S59) to this coarse localization result with the assigned address incident that receives from SLP1.

On the contrary, if this coarse localization result who calculates does not satisfy the QoP of SET1 request, then SLP2 transmits SUPL TRIGGERED RESPONSE message to SET2 and initiates triggering session (S58) with notice.SUPL TRIGGERED RESPONSE message comprises the localization method that will adopt in triggering session.

Subsequently, between SET2 and SLP2, periodically generate location sessions (S59).When each location sessions starts, between SET2 and SLP2, successfully exchange SUPL POS message.In this case, the auxiliary data (based on SET) that measurement that has received from SET2 based on SLP2 (SET is auxiliary) or SET2 have obtained from SLP2 is come calculating location.After finishing each location sessions, SLP2 compares the position of the SET2 that calculates and defined range (position that receives via SLP1).According to relatively, if the position of the SET2 that calculates corresponding to this defined range, then SLP2 carries out next step, otherwise SLP2 repeats this step (S59).

If the position of the SET2 that calculates is corresponding to the concrete zone by the SET1 appointment, then SLP2 stops location sessions (S60) by transmit SUPL END message to SET2, then transmits the RLP SSRLIR message (S61) of the POSRESULT that comprises SET2 to SLP1.

Therefore, SLP1 transmits the SUPL END message (S62) of the POSRESULT comprise SET2 to SET1, so SET1 discharges all resources that safe IP connects and release is relevant with this session with SLP1.

Fig. 5 illustration the 5th execution mode of request triggered location service method between the terminal in location information system according to the present invention.The 5th execution mode is similar to the 4th execution mode, and different is before transmitting RLP message to SLP2, has just stopped the connection between SLP1 and the SET1.That is, in the 4th execution mode, the IP connection between SLP1 and the SET1 is kept up to execution in step (S62), therefore causes the unnecessary waste of Radio Resource.

Therefore, in method corresponding to the 5th execution mode shown in Figure 5, after SLP1 determines that SET1 does not have the location-server SLP2 of roaming (S52) and definite target SET 2, thereby SLP1 connects (S70) to the IP that SET1 sends between SUPL END message termination SLP1 and the SET1.And then trigger service to the location-server SLP2 of SET2 request via RLP SSRLIR message.(therefore identical in S53～S61) and the 4th execution mode omitted the detailed description to them to step subsequently.

When the POSRESULT of the expectation that receives SET2 from SLP2 (S53), SLP1 transmits this given triggering result (S71) via SUPLREPORT message to SET1.Trigger to wait via WAPPUSH, SMS and transmit this SUPL REPORT message.

Fig. 6 illustration according to the present invention the 6th execution mode of request triggered location service method between the terminal in location information system, the 6th execution mode of the present invention has been to send SUPL END message with the 5th execution mode similarity and has been connected with the IP between termination SET1 and the SLP1.Yet their difference is to transmit the time of SUPL END message.

That is, in the 5th execution mode of the present invention, behind the position fixing process that finishes between SLP1 and the SET1, transmit SUPL END message immediately.In the 6th execution mode of the present invention, only after will starting, the location sessions between SLP2 affirmation SLP2 and the SET2 just transmits SUPL END message.When SLP2 receives SUPL TRIGGERE DSTART message and when SLP1 transmits RLPSSRLIR END message, this affirmation takes place from SET2.

Thereby when receiving SUPL TRIGGERED START message from SET2 and after RLP SSRLIR END message is transmitted to SLP1 (S80), SLP2 transmits SUPLTRIGGERED RESPONSE message to SET2, initiates triggering session (S81) with notice.For identical with the 5th execution mode thereafter step (S58～S61), omit detailed description to them.

After receiving RLP SSRLIR END message, SLP1 transmits SUPL END message to finish the connection (S81) between SET1 and the SLP1 to SET1.Subsequently, when receiving the POSRESULT of expectation from SLP2 (S61), SLP1 transmits given triggering result (S82) via SUPL RESPORT message to SET1.Trigger to wait via WAP PUSH, SMS and transmit SUPLRESPORT message.

Fig. 7 illustration according to the present invention the 7th execution mode of request triggered location service method between the terminal in location information system.

With reference to Fig. 7, the relevant request of receiving position from the application program of just among SET1, moving of the SUPL agency among the SET1.Preferably, the request that this position is relevant is meant periodic request or the zone issue request at target SET 2 positions.Here, Fig. 7 illustration the relevant request in this position be the situation of zone issue request.

When receiving the relevant request in position,, then SET1 is connected to packet data network (S90) if currently arbitrary network is not set up data as yet and connect.

In case set up the data connection, then the SET1 default addresses for use that adopts home network to provide is set up and is connected with the safe IP of location-server (SLP1), and starts the location sessions (S91) of target SET 2 to SLP1 transmission SET initiation message (SUPL SET INIT message).

SUPL SET INIT message comprises session id, target SET id, trigger mode, trigger message etc.At this, this target SET id is meant the sign of target SET 2.This trigger mode is meant that the SET of another SET type initiates to trigger service, and comprises periodic event parameter or zone issue parameter.Use with Fig. 1 and arrive request type identical triggering service mode shown in Figure 6.This trigger message is meant the triggering session parameter, and comprises cycle parameter and zone issue parameter.For example, this cycle parameter comprises the triggering cycle, and the zone issue parameter comprises defined range and event type.

SLP1 transmits SUPL END message to SET1 and confirms to receive triggering service request (S92).Then SET1 discharges safe IP connection based on received SUPL END message, and discharges all Radio Resources relevant with this session.In addition, SLP1 utilizes location-server (SLP2) that the target SET id (routing iinformation) that comprises in the SUPL SET INIT message determines target SET 2 (S93).That is, SLP1 by the contact local dns server or arbitrarily other entity that the SET2 address information can be converted to the information that can be used to get in touch with SLP2 determine SLP2.

In case determined SLP2, SLP1 just transmits trigger position request message (S94) to the location-server (SLP2) of target SET 2.The trigger position request message comprises session id, target SET id, trigger mode, trigger message etc.

Thereby when receiving the trigger position request message, SLP2 can use the trigger mode and the trigger message that receive to determine thus the triggering COS (periodic event or zone issue) that SET1 asks.Determine to carry out illustrative execution mode among the Fig. 7 that will be described below or Fig. 8 based on this.

When SLP2 had the mandate of serving about the triggering of SET1 request, SLP2 authorized SET1 and user application security information.If SET1 is authorized to and asks notice and checking, then SLP2 calculates the position (S95) of SET2 to SET2 transmission network-triggered location request message and execution network initiation position fixing process to utilize the SUPL localization method.

Yet, if the QoP (alignment quality) of SET1 request is satisfied in previous position of calculating, and if do not require notice and checking, SLP2 carries out next step (S96), and does not carry out previous step (S95).

After finishing the SET2 position calculation, SLP2 compares the position that calculates and the defined range of trigger message, whether checks in the given area generation area incident thus.According to the result who checks, if zone issue has taken place, then SLP2 transmits trigger position response message (S96) to SLP1, and SLP1 utilizes SUPL REPORT message to transmit the SET2 positional information (S97) that receives to SET1.

Fig. 8 illustration according to the present invention the 8th execution mode of request triggered location service method between the terminal in location information system, and show the situation of cycle location association requests.

That is the application program receiving cycle event request of the agency of the SUPL among the SET1, from just among SET1, moving.

After receiving the cycle Location Request and being connected to packet data network (S100), SET1 utilizes default addresses for use that home network provides to set up with SLP1 that safe IP is connected and transmit the location sessions (S101) that SUPL SET INIT message starts target SET 2 to SLP1.

As shown in Figure 8, SUPL SET INIT message comprises session id, target SET id, trigger mode, trigger message etc.At this, trigger mode is set to periodic event, and trigger message comprises cycle parameter (that is triggering cycle).

SLP1 utilizes location-server (SLP2) that the target SET id (routing iinformation) that comprises in the SUPL SET INIT message determines target SET 2 (S102).

In case determined the SLP2 of target SET 2, SLP1 just transmits trigger position request message (S103) to SLP2.This trigger position request message comprises session id, target SET id, trigger mode, trigger message etc.

SLP2 authorizes SET1 and user application security information.If SET1 is authorized to and asks to notify and checking, then SLP2 transmits network to SET2 and initiates the position (S104) that the position fixing process of trigger position request message and the initiation of execution network calculates SET2.

Yet, if the QoP (alignment quality) of SET1 request is satisfied in previous location of calculating, and if do not require notice and checking, SLP2 carries out next step (S109), and does not carry out previous step (S95).

Therefore, based on the cycle information that is included in the trigger message, SLP2 sends the trigger position response message (S105 and S107) that comprises the position that calculates in the position of each computation of Period SET2 and to SLP1.And SLP1 transmits the SET2 position (S106 and S108) that receives via SUPL REPORT message to SET1.

Thereafter, when in the end one-period is finished the position calculation of SET2, SLP2 utilizes the trigger position response message to transmit the position (S109) that calculates to SLP1 in the same manner, and SLP1 utilizes SUPL REPORT message to transmit the SET2 position (S110) that receives to SET1.In this case, each cycle indicated in index.

In the present invention, SET is as can being in the mobile radio station (MS), IS-95 MS etc. of subscriber equipment (UE), the GSM of UMTS one with the equipment of SUPL network service.In the present invention, SET is called as terminal.

As mentioned above, the present invention can provide more convenience by utilizing user terminal in the location information system to serve for the user for the counterpart terminal request triggered location of expectation based on the SUPL network.
