Description

Periodic positioning method in the GSM

Technical field

The present invention relates to GSM, more particularly, relate to a kind of based on the periodic positioning method in the positioning information system of secured user's layer location (SUPL).

Background technology

Usually; GSM has and calculates the position relevant functional unit of mobile communication terminal (after this only being called ' terminal ') in mobile communications network, and is provided for transmitting to special entity periodically or according to user's request the positioning service in the place (position) at terminal thus.

Network based 3GPP relevant or the internal networking structure of 3GPP2 and have various structure with positioning service.The position at terminal can utilize following method to calculate: the sub-district ID method that is used to transmit the sub-district ID of terminal affiliated subdistrict; Calculating is sent to radio wave the time that each base station spends from the terminal, uses triangulation to come the method in the place (position) of computing terminal then; Use the method for global positioning system (GPS) etc.

Yet, to the user positioning service is provided in order to utilize position calculation (location) method, will between terminal and location-server, send and receive considerable signaling and positional information.For providing this positioning service, that is,, promote widely just fast based on the positioning service in the place (position) at terminal by standardized so-called location technology.This technological model ground can provide through client layer and key-course.Secured user's layer location (SUPL) provides positioning service as the example of known location technology through client layer.

SUPL is the effective ways that are used to transmit the required place of terminal positioning (position) information.The SUPL agreement transmits the positioning auxiliary information such as global positioning system (GPS) auxiliary data.SUPL adopts the client layer data medium between portable terminal and network, to carry the location technology associated protocol.

Usually, in navigation system, the SUPL network relevant with positioning service comprises that roughly SUPL agency, SUPL locating platform (SLP) and SUPL launch terminal (SET).The logical services access point of the positional information of in fact measuring is used in SUPL agency expression.SLP representes that the interior accessing network resources of network portion is to obtain the SUPL Service Access Point of positional information.SET representes to be used to use the device of SUPL interface and SUPL network service.SET can represent, for example, and in the mobile radio station (MS) of the subscriber equipment of UMTS (UE), GSM, IS-95 MS, laptop computer, the PDA(Personal Digital Assistant) etc. one with SET function.SET also can represent the various portable terminals through broadband LAN (WLAN) access.

The SET that is connected to network via the client layer carrier supports the various processes by the SUPL defined.At this, the network of user's first registers is called as local network.Therefore when the user moved and be positioned at not another zone in home network area, respective regions is called as was visited network.SLP in the local network is known as local SLP (H-SLP), and the SLP that is visited in the network is known as by visit SLP (V-SLP).At this, when the SUPL process of beginning in the network, the initial SLP that connects of external client is called as request SLP (R-SLP).R-SLP be can be identical or different with H-SLP logic entity.In addition, the SET as the target of working as prelocalization (that is Position Tracking) is defined as target SET.

SLP as network element can comprise the SUPL centre of location (SPC) and SUPL place-centric (SLC); SPC is the entity that is used to calculate physical location; And SLC management SLP remove calculating place (position) other function the information, for example, roaming function and resource management function.Therefore, SET can pass through to communicate calculating location information (that is, carrying out the location) via SLC (that is, the acting server pattern) and SPC, and can come calculating location information (that is, execution is located) through being directly connected to SPC (that is non-acting server pattern).

Direct localization method based on SUPL is disclosed in correlation technique, yet, the periodic positioning method based on SUPL is not wherein proposed as yet.

Embodiment

Describe the present invention in detail referring now to accompanying drawing.

The present invention can implement in the SUPL network.Yet the present invention also can be used for radio (wireless) communication system of operating based on different specification.Below, will describe preferred implementation of the present invention.

The present invention proposes the periodic positioning method in a kind of positional information (location) system based on SUPL.Particularly, the present invention proposes a kind of method of coming execution cycle property location through the triggering that allows in server and the terminal each all to manage to produce periodically to locate.

Usually, the positioning service that in the navigation system based on SUPL, provides can be divided into service (that is network startup situation) and the service through SET (that is, SET-starts situation) through network.Positioning service can be divided into SET through directly and the H-SLP of local network exchange messages the acting server pattern of carrying out the location and SET through with H-SLP in SUPL place-centric (SLP) and the SUPL centre of location (SPC) exchange messages and carry out the non-acting server pattern of location.

In the present invention, according to the main body of management trigger information, periodically the location is divided into network-triggering situation or SET-triggering situation.The situation of dividing is divided into service (that is, network-startup situation) and the service (that is, SET-starts situation) through SET through network again, so that describe thus.

Fig. 1 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of first embodiment of the invention.The first execution mode illustration of the present invention network-the triggering situation and the network-startup situation of non-roaming acting server pattern.At this, SLP is corresponding to network side, and target SET (after this being called SET) is corresponding to end side.

When outside LCS client RQ cycle property location, the SUPL agency uses positioning reporting request (TLRR) message that has triggered running fix agreement (MLP) to ask from SLP location (S10).

MLP TLRR message can comprise the parameter such as ms-id, client-id, QoP and tlrr_event, and these parameters are location associated trigger parameters.At this; Ms-id representes localizing objects (SET), and QoP representes location (location tracking) result's that client is hoped accuracy (for example, time delay and spatial precision); And tlrr_event representes the definition of " periodically "; The time started and termination time (for example, 8am to 10am) of promptly periodically locating and the RQ cycle (for example, one hour the time interval) that is used for the periodicity location.MLP TLRR message (for example also can comprise the parameter relevant with the type of locator value; It representes the value that currency maybe obtains in the time recently when being difficult to follow the trail of currency), and the parameter that is used for being provided with to several Location Requests the priority of each Location Request.

The SLP that has received MLP TLRR message tables look-up to check whether SET can support SUPL through use, uses routing iinformation to check that target SET is current whether in SUPL roaming (S11) then.

Support SUPL and current not roaming if be checked through SET, then SLP sends SUPL initiation message SUPL INIT to SET, SET is begun SUPL process (S12).SUPL INIT message can comprise session-id, SLP pattern, SUPL pattern, with the localization method (posmethod) that uses etc.At this, the mode of operation of SLP modal representation SLP (that is, acting server pattern or non-acting server pattern), the type of SUPL modal representation location (for example, immediately, periodically, postpone), promptly trigger type information.At this, SUPL modal representation periodic service type location.

In addition, before execution in step S11, SLP confirms the privacy of SET.If the user need with the relevant notice of place (position) information, then SLP also comprises notifying parameters in MLP TLRR message.

Therefore, SLP sends SUPL INIT message through in SUPL INIT message, comprising periodic triggers information.This parameter can be used to notify and the relevant information in location periodically, and the SLP corresponding location (that is network-triggering situation) of just carrying out.At this, forms such as SUPL INIT message for example can push according to wireless application protocol (wap), Short Message Service (SMS) triggering, session initiation protocol (SIP) propelling movement are sent.

When current when any data not being set being connected between SET itself and the particular network, the SET that has received SUPL INIT message connects (S13) from packet data network (that is, 3GPP or 3GPP2) request msg.Connect in case data are set, the trigger message that the SET storage is sent through SUPL INIT message sends SUPL START message (S14) to SLP then.At this, SET sends the SET ability information through in SUPL START message, comprising the SET ability information.

SLP through the MLP triggered location report of using exchange reply (TLRA) message to the SUPL agency send to corresponding Location Request affirmation (that is, whether the location can carry out) (S15).After this, in response to this SUPL START message, SLP sends SUPL RESPONSE message (S16) to SET.At this, SUPL RESPONSE message can be replaced with SUPL TRIGGER message.In the case, execution in step S16 not.

After this, when special event produced (to every specific period) based on the trigger message of storing, SLP sent SUPL TRIGGER message with beginning position fixing process (S17) to SET.SET sends SUPL positioning starting message (that is, SUPL POSINIT) to SLP subsequently, so that the triggering session (S18) of beginning and SLP.SUPL POS INIT message can comprise the location identifier lid of expression session id, base station IDs etc., version, SET ability etc. at least.

Therefore, SLP and SET exchange (send and receive) continuous meassage, to carry out actual location, SLP or SET calculate the position (S19) of SET according to this continuous meassage then.Preferably, agreement (for example, RRLP, RRC or TIA-801) that the information that exchanges between SLP and the SET can comprise session id, will be used to locate etc.At this, (that is, the SET-auxiliary mode) can be carried out based on the location survey value that receives from SET through SLP in the location that is used for SET, or carries out (that is, based on SET pattern) through SET based on assisting of obtaining from SLP.Fig. 1 illustration in the SET auxiliary mode, carry out the example of location.Yet if in based on the pattern of SET, carry out the location, SET uses SUPL REPORT message to send the positional value (that is, posresult) (S20) that calculates to SLP.Therefore, SLP uses MLP TLREP message to send positional value that is calculated by SLP itself or the positional value (S21) that comes from the SET forwarding to the SUPL agency.

Afterwards; In follow-up locating periodically; SLP and SET use SUPL TRIGGER message, SUPL POS INIT message, SUPL POS process, SUPL REPORT message, MLP TLREP message to carry out the location that is used for respective cycle, after this send the positional value (S22-S26) of the SET that calculates to the SUPL agency.

Then, and when the series of periodic position fixing process all stops (end) (, when the location concluding time arrives), SLP sends SUPL END message, with the termination (S27) to SET notice SUPL process (or SUPL session).SET discharges IP connection and release all resources relevant with location sessions with SLP subsequently.

On the other hand, in Fig. 1, SUPL START and SUPL RESPONSE message can be omitted.In the case, can after sending SUPL POS INIT message, send MLP TLRA message.

Fig. 2 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of second embodiment of the invention, its illustration compare with first execution mode and be used for the periodically relatively long example of cycle of location.

As shown in Figure 2, for long periodicity locating periodically, SLP in the location of the ending use SUPL in each cycle END message termination (end) one-period (at this, discharging (disconnection) other SUPL connection except that the SUPL session) (S41).SLP is the starting point of one-period in the back subsequently, through reusing SUPL TRIGGER, carry out the location (S43) that is used for back one-period.At this, except that label, step (S30-S40) is identical with the step (S10-S20) of Fig. 1, therefore will no longer repeat its detailed description.

That is, when stopping (ends) to the periodicity position fixing process of one-period (S39) time, SLP sends SUPL END message to SET, to discharge the SUPL POS connection (S41) to one-period.SLP uses MLP TLREP message to send corresponding periodic location value (S42) to the SUPL agency subsequently.After this, SLP uses SUPL TRIGGER message to connect the SUPL POS connection that (disconnection) discharges, and notice SET carries out to the location (S43) of one-period, back.

Thus; When corresponding event produces; SLP and SET use SUPL POS INIT message, SUPL POS process and SUPL REPORT and MLP TLREP message to carry out the location to respective cycle, send corresponding positional value (S44-S47) to the SUPL agency then.When the series of periodic position fixing process stopped (end), SLP sent SUPL END message to SET, stops SUPL process (S48) with notice.

Fig. 3 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of third embodiment of the invention.The 3rd execution mode illustration of the present invention network-triggering situation and the SET-of non-roaming acting server pattern start situation.At this, SLP is corresponding to the local network side, and target SET (after this, being called SET) is corresponding to end side.

At first, when the SUPL proxy requests was periodically located, if currently between SET itself and particular network any data are not set are connected, then SET connected (S50) from packet data network (for example, 3GPP or 3GPP2) request msg.Connect in case data are set, SET just sends SUPL START message to SLP, with beginning periodicity Location Request process (S51).

SET comprises the reporting standards parameter in SUPL START message, so that periodically cycle, time started and the concluding time of Location Request are set.SET sends set information to SLP subsequently.

Receive the SLP memory cycle property locating information of SUPL START message, and used routing iinformation to check that this SET is current whether in SUPL roaming (S52).If be checked through the current not roaming of SET, then SLP sends SUPLRESPONSE message (853) in response to SUPL START message to SET.

After this, when corresponding event produced, SLP sent SUPL TRIGGER message to SET, with beginning periodicity position fixing process (S54).SET sends SUPL POS INIT message to SLP, with the triggering session (S55) of beginning with SLP.At this, for the initial period location that produces, SUPLTRIGGER message can be used the SUPL RESPONSE message replacement of step (S53), or SUPLRESPONSE message can be used the SUPL TRIGGER message replacement of step (S54).

Thus, SUPL POS message and the SET that SLP is used to carry out the location exchanges (send and receive) location protocol (for example, RRLP, RRC, TIA-801 etc.), the position (S56) of calculating SET thus continuously.At this, can carry out (that is, the SET-auxiliary mode) based on the location survey value that receives from SET through SLP to the location of SET, or carry out (that is, based on SET pattern) based on assisting of obtaining from SLP through SET.

Should locate if in the SET auxiliary mode, carry out, then SLP uses SUPL REPORT message to send the positional value (that is, posresult) (S57) that calculates to SET.If under based on the pattern of SET, carry out and should locate, then SLP does not send SUPL REPORT message to SET.Therefore, SET sends positional value that calculates through SET itself or the positional value that receives from SLP to the SUPL agency.

After this; In locating periodically subsequently; As stated, SLP and SET use SUPLTRIGGER message, SUPL POS INIT message, SUPL POS process and SUPLREPORT message to carry out the location that is used for respective cycle, after this send the positional value (S58-S61) of the SET that calculates to SET.

Then, when whole periodicity position fixing process stopped (end), SLP sent SUPLEND message to SET, with the termination (S62) to SET notice SUPL process (or SUPL session).SET discharges IP connection and release all resources relevant with location sessions with SLP subsequently.

Fig. 4 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of four embodiment of the invention, its illustration compare with the 3rd execution mode and be used for the periodically relatively long example of cycle of location.

As shown in Figure 4, for long cycle locating periodically, SLP uses SUPL END message to stop (ends) to the location (that is, discharging or break off the SUPL connection) of one-period (S78) in the ending in each cycle.SLP in the starting point of subsequent cycle, carries out the location (S79) that is used for subsequent cycle through reusing SUPLTRIGGER subsequently.At this, except that label, step (S70-S77) is identical with step (S50-S57), will no longer repeat its detailed description thus.

That is, when the periodicity position fixing process for one-period stops (S76), SLP sends SUPL END message to SET, and the SUPL POS that discharges then for one-period connects (or triggering connection) (S78).

Afterwards, SLP sends SUPL TRIGGER message to SET, and SET carries out the location (S79) to subsequent cycle with notice.At this, when between SET itself and the particular network any data not being set and being connected, SET can connect from packet data network (for example, 3GPP or 3GPP2) request msg.

Thus, when corresponding event produced, SLP and SET used SUPL POS INIT message, SUPL POS process and SUPL REPORT message to carry out the location that is used for respective cycle, and in some cases, send corresponding positional value (S80-S82) to SET.Then, when the series of periodic position fixing process stopped (end), SLP sent SUPL END message to SET, with the termination (S83) of the notice whole SUPL process of SET (or triggering session).

Fig. 5 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of fifth embodiment of the invention.The 5th execution mode illustration of the present invention the SET-triggering situation and the network-startup situation of non-roaming acting server pattern.At this, SLP is corresponding to the local network side, and target SET (after this, being called SET) is corresponding to end side.

At first, when outside LCS client RQ cycle property location, the SUPL agency uses the MLPTLRR message request from SLP location (S90).As stated, MLP TLRR message can comprise such as ms-id, client-id, QoP, the parameter of tlrr_event etc.Tlrr_event representes the definition of ' periodically ', that is, and and the time started and concluding time (for example, 8am to 10am) of periodically locating and the RQ cycle (for example, one hour the time interval) that is used for the periodicity location.MLP TLRR message also can comprise the parameter relevant with the type of positional value (for example, the value that its expression currency maybe obtains) in the time recently when being difficult to follow the trail of currency, and for each Location Request of several Location Requests the parameter of priority is set.

When receiving MLP TLRR message, SLP uses to table look-up to check whether SET can support SUPL, uses routing iinformation to check that target SET is current whether in SUPL roaming (S91) then.

Support SUPL and current not roaming if be checked through SET, then SLP sends SUPL INIT message with beginning SUPL process (S92) to SET.SUPL INIT message must comprise the parameter such as session-id, posmethod, SLP pattern, SUPL pattern etc. at least.The SUPL modal representation triggers type information, indication cycle's sex service type in the 5th execution mode of the present invention.

Before execution in step S91, the privacy of SLP inspection SET.If the user need the notice relevant with positional information, then in MLP TLRR message, can also comprise notifying parameters.

SLP comprises the reporting standards parameter, and this parameter is the trigger parameter (or trigger message) of the SUPL INIT message that is used for sending.SLP operation report canonical parameter is sent and the relevant trigger message in periodicity location that receives from outside LCS client to SET.That is, SLP will produce the trigger message of periodically locating and pass on to SET (that is, the SET-triggering situation), when in SET, producing corresponding event with box lunch, allow to carry out actual location.For example, reporting standards can comprise cycle, time started and the concluding time that is used for requirement periodicity Location Request.

When between SET itself and the particular network any data not being set and being connected, the SET that has received SUPL INIT message connects (S93) from packet data network (for example, 3GPP or 3GPP2) request msg.

Under the situation that is provided with the data connection, after this trigger message that the SET storage is sent through SUPL INIT message sends SUPL START message (S94) to SLP.At this, SET sends the SET ability information through in SUPL START message, comprising the SET ability information.

SLP sends the affirmation (S95) to corresponding Location Request through using MLP TLRA message to the SUPL agency.SLP sends SUPLRESPONSE message in response to SUPL START message subsequently, with when corresponding event takes place, allows SET to begin position fixing process (S96).

After this, when based on the trigger message of storing (that is, being used for periodically each cycle of location) generation corresponding event, SET sends SUPL POS INIT message to SLP, begins position fixing process (S97) to utilize SLP.At this, if the TCP/IP between SET and the SLP connects and is terminated (releases) after sending SUPL RESPONSE message, then SET must reset this data connection before sending SUPL POS INIT message.

Thus, SET and SLP exchange the message that is used for carrying out with SLP actual location continuously, to calculate the position (S98) of SET.At this, can calculate (that is, the SET-auxiliary mode) based on the location survey value that receives from SET through SLP for the location of SET, maybe can be through SLP based on carrying out from assisting of SLP acquisition.

When under based on the pattern of SET, carrying out the location, SET uses SUPL REPORT message to send the positional value (that is, posresult) (S99) that calculates to SLP.When under the SET-auxiliary mode, carrying out the location, SLP does not send SUPL REPORT message.Thus, SLP uses TLREP message to send corresponding positional value (S100) to the SUPL agency.

In locating periodically subsequently; The positional value (S101-S104) that sends the SET that calculates is acted on behalf of to SUPL in SLP and the SET location through using SUPL POS INIT message, SUPL POS process, SUPL REPORT and MLP TLREP message to carry out respective cycle after this.

Afterwards, and when the series of periodic position fixing process all stops (end) (, in the location concluding time), SLP sends SUPL END message to SET, and SET stops SUPL process (or SUPL session) with notice.SET discharges IP connection and release all resources relevant with location sessions with SLP subsequently.

On the other hand, in Fig. 5, can omit SUPL START message and SUPL REPORT message.In the case, can after sending SUPL POS INIT message, send MLP TLRA message.

Fig. 6 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of sixth embodiment of the invention, its illustration when the cycle of comparing location periodically with the 5th execution mode is longer relatively, SET can break off or connect the example of SUPL session to each cycle.

As shown in Figure 6, for long periodicity locating periodically, SLP uses location (at this, discharging (disconnection) SUPL connection) that SUPL END message stops (ends) one-period (S120) in the ending in each cycle.The starting point of one-period resends SUPL START message to SLP to SET in the back subsequently, is used for the location (S122) of one-period, back with execution.At this, except label, step (S110-S119) is identical with step (S90-S99), will no longer repeat its detailed description thus.

That is, when the periodicity position fixing process for one-period stops (S118), SLP sends SUPL END message to SET, and the SUPL POS that is used for one-period with release connects (S120).After this, SLP uses MLP TLREP message to send corresponding periodic location value (S121) to the SUPL agency.

Then; In locating periodically subsequently; SET uses SUPL START, SUPLREPONSE, SUPL POS INIT message, SUPL POS process and SUPL REPORT and MLP TLREP message to carry out the location to respective cycle, after this sends corresponding positional value (S122-S127) to the SUPL agency.At this, SUPL START message can be used for notifying SLP to begin the location of one-period, back.When the series of periodic position fixing process stopped (end), SLP sent SUPL END message to SET, stopped SUPL process (S128) with logical SET.

Fig. 7 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of seventh embodiment of the invention.The 7th execution mode illustration when SLP can not use SUPL INIT message to send reporting standards because of the restriction of the size of SUPL INIT message, SLP uses new SUPL TRIGGERREQUEST message to send the example of reporting standards.

Promptly; The difference of the 7th execution mode of the present invention and the 5th execution mode is to have increased SUPL TRIGGER REQUEST and SUPL TRIGGER RESPONSE message, and to SUPL INIT message increased the SUPL pattern (its be used to discern immediately, periodically or postpone the parameter of location).Except label, other step is identical with step in the 5th execution mode.

Therefore; After carrying out above-mentioned steps (S130-S134); SLP uses SUPL TRIGGERREQUEST message to send the information (S135) relevant with the periodicity location to SET, so that make SET arrange periodically location according to corresponding information, and allows SET to carry out user's affirmation individually.The periodic triggers information that the SET storage is sent through SUPL TRIGGER REQUEST message after this in response to SUPL TRIGGER REQUEST message, is sent SUPL TRIGGERRESPONSE message (136).

But different with Fig. 5, as shown in Figure 7, SLP receives the SUPL TRIGGERRESPONSE message from SET, sends MLP TLRA message (S137) to the SUPL agency then.Because SLP sends the SUPL TRIGGERREQUEST message that comprises with the trigger message that periodically location is relevant to SET; Receive SUPL TRIGGER RESPONSE message in response to SUPL TRIGGER REQUEST message from SET then, therefore only the reception of SUPL TRIGGERRESPONSE message could be notified: send to SET fully with the relevant trigger message in periodicity location.Yet SUPL TRIGGER RESPONSE message can be omitted.In the case, SLP sends SUPL TRIGGER REQUEST message, sends MLP TLRA message to the SUPL agency immediately then.

SUPL INIT message can be sent according to the SMS send mode.Thus; When the reporting standards parameter can not all be included among the SMS; SUPL TRIGGER REQUEST message can represent to be used for sending separately the message of reporting standards parameter, and SUPL TRIGGER RESPONSE message is corresponding to the message of response SUPL TRIGGER REQUEST message.Therefore, in Fig. 5, can omit SUPL START message and SUPL RESPONSE message.Yet; In Fig. 7; In order to send through SUPL TRIGGER REQUEST message and periodically to locate relevant trigger message and receive SUPL TRIGGER RESPONSE; SET must at first send SUPLSTART message to SLP, to obtain the acceptance to the periodicity location among the SUPL INIT that is included in from SLP.Thus, can only omit SUPL RESPONSE message.

Even in the 7th execution mode of the present invention, the periodicity locating periodically for long can change process so that can open (connection) SUPL session in each cycle through SET.In the case, before sending SUPL POS INIT message, increase SUPLSTART message and SUPL RESPONSE message to each locating periodically.If do not use (requirement) SUPL REPORT message, then after this SUPL POS process, increase SUPL END message.If use SUPLREPORT message, then after SUPL REPORT message, increase SUPL END message.

Fig. 8 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of eighth embodiment of the invention.The 8th execution mode illustration SET-triggering situation and the SET-of non-roaming acting server pattern start situation.

At first, when the SUPL proxy requests is periodically located, be not connected if between SET itself and particular network, any data are set, then SET connects (S150) from packet data network (for example, 3GPP or 3GPP2) request msg.

After the data connection was set, SET sent SUPL START message to SLP, with beginning periodicity Location Request process (S151).At this, SET comprises the tlrr_event parameter in SUPL START message, so that periodically cycle, time started and the termination time of Location Request to be set, sends SUPL START message to SLP thus.That is, SET is in property SUPL of the following execution cycle of situation of management trigger information process, so SET can not send the tlrr_event parameter to SLP.Yet sending tlrr_event to SLP is in order to locate relevant information to SLP notice and resource management with periodicity earlier.

Whether the SLP that has received SUPL START message uses routing iinformation inspection SET current in SUPL roaming (S152).If SET is roaming not, then SLP sends SUPL RESPONSE message (S153) in response to SUPL START message.

Afterwards, when producing particular event based on the trigger message that prestores (at locating periodically), SET sends SUPL POS INIT message to SLP, with beginning periodicity position fixing process (S154).At this, SET can use that event_trigger parameter notice SLP is current to have reached periodically locating periodically, and can use the residue period of the whole locating periodically of event_trigger parameter notice SLP.At this, if after sending SUPL RESPONSE message, stopped SLP and has been connected with TCP/IP between the SET, then before sending SUPL POS INIT message, SET must reset this data connection.

Therefore, SET and SLP exchange the message that is used to carry out actual location continuously, to calculate the position (S155) of SET.At this, can carry out (being the SET-auxiliary mode) based on the location survey value that receives from SET through SLP for the location of SET, maybe can carry out based on obtaining to assist (that is, based on SET pattern) through SET from SLP.

Fig. 8 illustration the location of in pattern, carrying out based on SET.Yet if in the SET auxiliary mode, carry out the location, SLP uses SUPL REPORT message to send the positional value (being posresult) that calculates (S156) to SET.Thus, SLP sends positional value that calculates through SET itself or the positional value that receives from SLP to the SUPL agency.

Afterwards, in locating periodically subsequently, as stated, SLP and SET use SUPL POSINIT message, SUPL POS process and SUPL REPORT message to carry out the location to respective cycle, thereby calculate the positional value (S157-S159) of SET.Then, when the series of periodic position fixing process all stopped (end), SLP sent SUPL END message to SET, and SET stops SUPL process (S160) with notice.SET discharges IP connection and release all resources relevant with position fixing process with SLP subsequently.

Fig. 9 is an illustration according to the diagrammatic sketch of the periodicity position fixing process of nineth embodiment of the invention, its illustration compare relatively long example of the cycle of location periodically with the 8th execution mode.

As shown in Figure 9, for long periodicity locating periodically, SLP in the location of each use SUPL END message termination (end) one-period that periodically ends up (promptly discharging or disconnection SUPL connection) (S176).SET resends SUPL START message in the starting point of back one-period to SLP, to carry out the location (S177) of one-period, back.At this, except label, step (S170-S175) is identical with step (S150-S155), no longer repeats its detailed description thus.

That is, when the periodicity position fixing process to one-period stops (S175), SLP sends SUPL END message to SET, and stops (end) SUPL POS session (S176) to one-period.

Afterwards, in one locating periodically of back, SET uses SUPL START, SUPLRESPONSE, SUPL POS INIT and SUPL POS process message to carry out the location (S177-S180) to respective cycle again.In the case, the tlrr_event of SUPL START message comprises the periodic quantity that reduces.Be not connected if between SET itself and particular network, any data are set, then SET connected from packet data network (for example, 3GPP or 3GPP2) request msg before sending SUPL START message.

Thus, when the series of periodic finder stopped (end), SLP sent SUPL END message to SET, and SET stops SUPL process (S181) with notice.

As stated, in the present invention, can provide a kind of, to the user various localization methods are provided so that allow based on the periodic positioning method in the location information system of SUPL.

Under the situation that does not break away from spirit of the present invention or inner characteristic; The present invention can be embodied as some kinds of forms; Should also be appreciated that; Above-mentioned execution mode is not limited by above-described any details, unless otherwise mentioned, otherwise carries out wide in range explanation in its spirit that should in accompanying claims, define and the scope; Therefore be intended to comprise in the boundary that falls into accompanying claims and the scope, perhaps fall into the interior whole variations and the modification of equivalency range of this said boundary and scope through accompanying claims.
