Yet, provide positioning service in order to utilize position calculation (location) method to the user, will between terminal and location-server, send and receive considerable signaling and positional information.For providing this positioning service by standardized so-called location technology, that is, promote widely just fast based on the positioning service of the location (position) of terminal.This technology typically can provide by user plane and control plane.As the example of known location technology, secure user plane location (SUPL) provides positioning service by user plane.
SUPL is for the effective ways that transmit positional information, and this positional information is that terminal positioning is calculated required.The SUPL agreement transmits the positioning auxiliary information such as global positioning system (GPS) auxiliary data.SUPL adopts the user plane data carrier to carry the location technology associated protocol between portable terminal and network.
Usually, in navigation system, the SUPL network relevant with positioning service comprises that roughly SUPL agency, SUPL locating platform (SLP) and SUPL enable terminal (SET).The logical services access point of the positional information of in fact measuring is used in SUPL agency expression.SLP represents that interviewed Internet resources are with the SUPL Service Access Point in the network portion that obtains positional information.SET represents for the device that uses SUPL interface and SUPL network service.SET for example can represent one of mobile radio station (MS), IS-95MS, the portable computer with SET function, personal digital assistant (PDA) of subscriber equipment (UE), the GSM of UMTS etc.SET also can represent the various portable terminals by broadband LAN (WLAN) access.
The SET that is connected to network via user plane bearer supports by the defined various programs of SUPL.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 was called as interviewed network.SLP in the local network is known as this locality-SLP (H-SLP), and the SLP in the interviewed network is known as interviewed-SLP (V-SLP).At this, when the SUPL process in network began, the initial SLP that connects of external client was 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, follow the tracks of the position) is defined as target SET.
In addition, SLP as network element can comprise the SUPL centre of location (SPC) and SUPL place-centric (SLC), SPC is for the entity that calculates physical location, and the function except calculating place (position) information of SLC management SLP, for example, roaming function and resource management function.Therefore, SET can be by communicating calculating location information (namely via SLC (that is, acting server pattern) and SPC, carry out the location), and can come calculating location information (that is, carrying out the location) by being directly connected to SPC (that is, non-proxy server mode).

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 based on the different specification running.Below, preferred implementation of the present invention will be described.
The invention provides in server and terminal management with in the situation based on the relevant trigger message in the location in location (place/positional information) system of SUPL, be used for (for example locating (location tracking) based on zone (zone is relevant), when fast mobile terminal in the specific region, be positioned at specific zone, when perhaps shifting out the specific region) process.
Location based on the zone according to the present invention can be illustrated as when corresponding event occurs periodically or according to the trigger message that prestores, SLP or SET begin position fixing process and whether are positioned at trigger message (namely to determine that SET is current, area event information) in the defined respective regions, thus, if determine that SET is currently located in the described respective regions, then report corresponding event.At this, zone issue represents verification terminal immigration specific region or shifts out the specific region or be arranged in this zone, corresponding event occurs thus.In addition, this zone is corresponding to the specific region that exists among the present invention, and this expression is used for the information of defined range event.
Usually, the positioning service that provides in the navigation system based on SUPL can be divided into service (that is, network-startup situation) and the service by SET (that is, SET-starts situation) by network.Positioning service can be divided into SET by directly and the H-SLP exchange message of local network carry out the acting server pattern of position fixing process and SET by with H-SLP in SUPL place-centric (SLP) and the SUPL centre of location (SPC) the exchange message non-proxy server mode of carrying out position fixing process.
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.Situation through dividing is subdivided into service (that is, network-startup situation) by network and the service (that is, SET-starts situation) by SET in order to describe thus.
Fig. 1 is illustration according to the diagram based on the position fixing process in zone of first embodiment of the invention, its illustration network-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 customer requirement during based on the location in zone, the SUPL agency uses running fix agreement (MLP) triggered location report request (TLRR) message from the location (S10) of SLP request based on the zone.
MLP TLRR message can comprise such as ms-id, client-id, QoP, the parameter of tlrr_ event etc., ms-id represents the tracked target in its position (SET), QoP represents that positional accuracy (for example, time delay and spatial precision), and tlrr_ representations of events area event information, namely with based on the relevant characteristic in the location in zone (for example, whether localizing objects (for example terminal) moves into the specific region or shifts out the specific region, or be arranged in specific region etc.) and the information of specific region (for example the title of specific region, accurate positional value etc.).
MLP TLRR message can also comprise that (the expression currency is maybe when being difficult to calculating or obtaining currency with positional value, the value that obtains in the recently time) parameter that type is relevant, and for the parameter that priority is set for each Location Request of some Location Requests.
The SLP that has received MLP TLRR message is with tabling look-up to verify whether target SET supports SUPL, and verifies with routing iinformation that described target SET is current and whether just carrying out SUPL roaming (S11).
Support SUPL and current not roaming if confirm SET, then SLP sends the initialized SUPL INIT of SUPL message to SET, in order to begin (startup) SUPL process (S12) with this SET.At this, SUPL INIT message sends such as pushing the forms such as (push), Short Message Service (SMS) triggering, session initiation protocol (SIP) propelling movement, UDP/IP according to WAP (wireless application protocol) (WAP).
SUPL INIT message can comprise session-id, SLP pattern, SUPL pattern, localization method (posmethod) to be used etc. at least.At this, the mode of operation of SLP modal representation SLP (that is, acting server pattern or non-proxy server mode), the type of SUPL modal representation location (for example, directly periodically locate the location, based on zone location etc.).In addition, before execution in step S11, SLP confirms the privacy of (checking) SET.If the user need to relate to the notice of place (position) information, then SLP has also comprised notifying parameters in MLP TLRR message.
Therefore, SLP sends SUPL INIT message by comprising therein the trigger message based on the zone.This parameter can be used to notification target SET with based on the relevant information of zone location and the corresponding location (that is, network-triggering situation) of just carrying out by SLP.
When current when any data not being set connecting between SET itself and 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 be provided with data, then then the SET storage sends SUPL to SLP and begins message (S14) by the trigger message of SUPL INIT message transmission.At this, SET begins to send in the message described SET ability information by the SET ability information being included in SUPL.
For the corresponding Location Request to the SUPL agency, SLP is by using MLP triggered location report (TLRA) information of replying that exchanges to send affirmation (that is, whether the location can carry out) (S15).After this, SLP begins message to SET transmission SUPL response message (S16) in response to SUPL.At this, the SUPL response message can trigger message with SUPL and replace.In the case, execution in step S16 not.
Afterwards, for the trigger message with storage checks whether corresponding event has occured, namely for the position that periodically checks terminal whether corresponding to event relevant position occuring, SLP sends SUPL to SET and triggers message, thereby notice SET location begins (S17).SET sends SUPL positioning starting SUPL POS INIT message, to begin actual location correlated process (S18).At this, SUPL POS INIT message can comprise at least: the location identifier (lid) of expression session id, base station IDs etc.; Version; SET ability etc.
SLP and SET exchange (sending and receiving) message continuously, and to carry out actual location, then SLP or SET are according to the position (S19) of this continuous message calculating SET.Preferably, the information that exchanges between SLP and SET can comprise: session id, be ready to use in the agreement (for example, RRLP, RRC or TIA-801) of location etc.In addition, SET does not accurately calculate actual position value with SLP.On the contrary, SET can pass through only reported position identifier (lid) of SUPL report message.
(being the SET-auxiliary mode) can be carried out based on the location survey that receives from SET by SLP in the location (that is, position calculation) that is used for SET, or assists to carry out (namely based on the SET pattern) by SET based on what obtain from SLP.The part illustration that represents with the solid line among Fig. 1 the location by the SET-auxiliary mode.But if carry out the location in based on the SET pattern, then SET uses the SUPL report message (S20) (to be shown in broken lines) to the positional value (being posresult) that the SLP transmission calculates.
When executing location (position calculation), SLP determines whether the calculating location of (checking) this SET is identical with the area event information that prestores.If determine that the positional value of SET is identical with the area event information that prestores, then SLP uses MLP TLREP message to send corresponding positional value (S21) to the SUPL agency.If not identical, then SLP periodically carries out following position fixing process.
That is, during the follow-up location based on the zone, SLP sends SUPL to SET and triggers message with notice location beginning (S22).SET sends SUPL POS INIT message to begin actual position fixing process (S23) to SLP.Afterwards, SLP and SET exchange mutually the message that is used for carrying out actual location, the position (S24) of calculating thus SET continuously.At this, if carry out location (position calculation) in based on the SET pattern, then SLP is by utilizing the SUPL report message to receive the positional value (S25) that calculates from SET.In addition, SET does not accurately calculate actual position value with SLP.On the contrary, SET can pass through only reported position identifier (lid) of SUPL report message.
Thus, when checking out the position of SET by SUPL triggering message, SUPL POS INIT message, SUPL POS process and SUPL report message, SLP determines again whether the position of SET is identical with the area event information that prestores.If determine the positional value of SET identical with the area event information that prestores (that is, if corresponding event occurs), then SLP acts on behalf of the locator value (S26) that sends based on the zone by MLP TLREP message to SUPL.Then SLP sends the SUPL end to SET and stops SUPL process (or SUPL session) (S27) with notice.The SET that has received the SUPL end discharges all resources relevant with location sessions with the IP connection of SLP and release.
On the other hand, the SUPL among Fig. 1 begins can be omitted with the SUPL response message.In the case, can after sending SUPL POS INIT message, send MLP TLRA message.
For the long period based on zone location, location-server can send the SUPL end to terminal in the ending in each cycle, finishes thus the location of (termination) one-period.
Fig. 2 is illustration according to the view based on the position fixing process in zone of second embodiment of the invention, its illustration network-triggering situation and the SET-of non-roaming acting server pattern start situation.
At first, when SUPL proxy requests during based on the location in zone, when between SET itself and the particular network any data not being set and being connected, SET connects (S30) from packet data network (for example, 3GPP or 3GPP2) request msg.
Connect in case data are set, SET sends SUPL to SLP and begins message with beginning based on the position fixing process in zone (that is, move in the specific region or shift out the situation of specific region) (S31).At this, SET begins to insert in the message reporting standards parameter that (comprising) represents area event information at SUPL.Thus, SET can based on the characteristic of zone location (for example send to SLP, whether localizing objects (for example terminal) moves in the specific region or shifts out the specific region, or it is medium to be positioned at the specific region) with the information relevant with this specific region (for example, the title of specific region, exact position value etc.).
Receive the SLP storage area event information that SUPL begins message, and used routing iinformation to verify the current whether SUPL roaming (S32) of this SET.If confirm the current not roaming of SET, SLP begins message to SET transmission SUPL response message (S33) in response to SUPL so.
Afterwards, for whether the trigger message inspection of using storage corresponding event occurs, namely for the position that periodically checks terminal whether corresponding to event relevant position occuring, SLP sends SUPL to SET and triggers message and notify thus the SET location to begin (S34).SET sends SUPL positioning starting (SUPL POS INIT) message, to start (beginning) actual location correlated process (S35).At this, if the initial location that generates, then SUPL triggering message can be replaced by the SUPL response message.
SLP and SET exchange are used for carrying out the continuous meassage of actual location.SLP or SET can calculate the position (S36) of SET by utilizing this continuous meassage.At this, SLP does not accurately calculate actual position value with SET.On the contrary, SLP can only report lid by the SUPL report message.
The location (being that calculate the position) that is used for SET can use the location survey that receives from SET to carry out (that is, the SET-auxiliary mode) by SLP, perhaps uses from what SLP obtained by SET and assists to carry out (that is, based on the SET pattern).The part illustration that represents with the solid line among Fig. 1 by the location based on the SET pattern.But if carry out the location by the SET-auxiliary mode, then SLP uses the SUPL report message to send the positional value (S37) (being shown in broken lines) that calculates to SET.When executing the location, SLP checks whether the position of the SET that calculates is identical with the area event information of storage, determines whether thus to have occured corresponding event.
In locating periodically subsequently, SLP and SET exchange as mentioned above SUPL and trigger message, SUPL POS INIT message, SUPL POS process and SUPL report message, to re-execute location (S38-S41).At this, SLP can use the SUPL report message and only report lid, but not accurately calculates actual position value between SLP and SET.
When executing a series of position fixing process based on the zone, SLP sends the SUPL end to SET and stops SUPL process (or SUPL session) (S42) with notice SET.Then SET discharges all resources relevant with location sessions with the IP connection of SLP and release.
Fig. 3 is illustration according to the diagram based on the position fixing process in zone of third embodiment of the invention, its illustration compare with the second execution mode, based on the relatively long situation of the locating periodically in zone.
As shown in Figure 3, for the long period based on the location in zone, SLP uses the SUPL end in location (that is, only discharge SUPL and connect, keep simultaneously the SUPL session) that ending place in each cycle stops one-period (S58).Then SLP reuses SUPL and triggers message is carried out a rear cycle at the starting point place in a rear cycle location (S59).At this, except reference number, step (S50-S57) is identical with step (S30-S37), therefore no longer repeats its detailed description.
That is, when execute one-period based on the position fixing process in zone the time (S57), SLP sends the SUPL end to SET, the SUPL POS that discharges thus for described one-period connects (S58).After this, SLP sends SUPL to SET and triggers message, so that notice SET carries out the location (S59) in a rear cycle.At this, when between SET itself and the particular network any data not being set and being connected, SET connects from packet data network (for example, 3GPP or 3GPP2) request msg.
Thus, when corresponding event occured, SLP and SET intercoursed SUPL POS INIT message, SUPL POS process and SUPL report message, to carry out the location (S60-S62) of respective cycle.When executing a series of position fixing process based on the zone, SLP sends the SUPL end to SET, notifies thus the termination (S63) of SET SUPL process.
Fig. 4 is illustration according to the diagram based on the position fixing process in zone of four embodiment of the invention, its illustration SET-triggering situation and the network-startup situation of non-roaming acting server pattern, more particularly, its illustration by carry out the situation of location based on the pattern of SET.
When outside LCS client requests during based on the location in zone, the SUPL agency uses running fix agreement (MLP) triggered location report request (TLRR) message from the location (S70) of SLP request based on the zone.MLP TLRR message can comprise the parameter such as ms-id, client-id, QoP, tlrr_ event etc., ms-id represents tracked target (SET), QoP represents positional accuracy, and tlrr_ representations of events area event information, that is, based on the characteristic of location and the specific region in zone.In addition, MLP TLRR message also can comprise the parameter relevant with the type of positional value, and the parameter of priority that is used for arranging each Location Request of several Location Requests.
The SLP that has received MLP TLRR message is with tabling look-up to verify whether SET supports SUPL, and verifies that with routing iinformation this SET is current whether just in SUPL roaming (S71).Support SUPL and current not in roaming if confirm SET, then SLP sends SUPLINIT message to SET, begins SUPL process (S72) to utilize this SET.At this, described SUPL INIT message is such as sending according to forms such as WAP (wireless application protocol) (WAP) propelling movement, Short Message Service (SMS) triggering, session initiation protocol (SIP) propelling movement, UDP/ID.
SUPL INIT message can comprise the parameter such as session-id, SLP pattern, SUPL pattern, posmethod etc. at least.At this, the operator scheme of SLP modal representation SLP (for example, acting server pattern or non-proxy server mode), the type of SUPL modal representation location (for example, direct location, periodically locate and based on the location in zone).Before execution in step S71, SLP can check the privacy of SET.If the user need to relate to the notice of location, then in SUPLINIT message, also can comprise notifying parameters.
SLP comprises the reporting standards parameter in SUPL INIT message, to send SUPL INIT message.SLP operation report canonical parameter to SET send received from outside LCS client with based on the relevant trigger message in the location in zone, i.e. area event information.That is SLP transmits the trigger message T (that is, SET-triggering situation) that produces based on the location in zone to SET.When occuring, corresponding event allow thus SET to carry out actual location.
In fact the specific region (for example, Seoul or Shingil 1-dong) that utilizes MLP TLRR message to send from the SUPL Agency is not expressed as the cell i d on the network.Therefore, if necessary, SLP can change the specific region into the network parameter such as cell i d etc.Then SLP uses the network parameter of SUPLINIT message transmission through changing.Alternatively, SLP uses SUPL INIT message to send same as before the specific region title that is sent by MLP TLRR message.Can send by the agreement that independently provides by the value that is transformed into network parameter that SET distinguishes.
Be not connected if between SET itself and particular network any data are set, the data that the SET that has then received SUPL INIT message arranges with packet data network (for example, 3GPP or 3GPP2) connect (S73).When data network was set, the SET storage began message (S74) by the trigger message (being area event information) of SUPL INIT message transmission and with backward SLP transmission SUPL.At this, SET also begins to send in the message this SET ability information by the SET ability information being included in SUPL.
SLP is by using MLP TLRA message to send for the affirmation (that is, whether carrying out this location) of corresponding Location Request (S75) to the SUPL agency.SLP sends SUPL response message (S76) in response to SUPL begins message to SET subsequently.
Afterwards, when the information that need to periodically need by the SLP calculated location value (namely, auxiliary data) time, for example, when the information that need to transmit by SLP so as fast processing (using in the situation of A-GPS when should be the data that the actual location carried out by SET measures, described data comprise: the current track of satellite, the number of satellite of terminal under the satellite-signal that current location can receive etc.), described SET sends SUPL POS INIT message to SLP and begins thus position fixing process (S77).At this, if after sending the SUPL response message, the TCP/IP connection between SET and the SLP is released, and then before sending SUPL POS INIT message, described SET must reset data and connect.
Therefore, SLP and SET exchange continuously for the message of carrying out actual location (that is, carrying out SUPL POS process).Thus, (that is, the SET-auxiliary mode) can be carried out based on the location survey that receives from this SET by SLP in the location (being that calculate the position) that is used for SET, perhaps assists to carry out (that is, based on the SET pattern) by this SET based on what obtain from SLP.
Fig. 4 illustration the location by carrying out based on the SET pattern.Therefore, when stopping SUPL POS process, SET compares the actual position value that arranges in calculated location value and the area event information, and whether inspection zone issue has occured thus.If be checked through zone issue has occured, then SET uses the SUPL report message to send the positional value (S79) that calculates to SLP.SLP uses MLPTLREP message to send the positional value (S80) that receives from SET to the SUPL agency.At this, SET comprises the information of the characteristic (for example, SET moves on in the specific region or shifts out this zone, or is positioned at this specific region) that represents corresponding event in the trigger event parameter of SUPL report message, thus described information is sent to SLP.
On the other hand, do not have the generation area event if be checked through, SET periodically carries out following position fixing process so.In the case, not execution in step S79 and S80.
That is in the locating periodically based on the zone subsequently, SET sends SUPL POSINIT message with notice SLP location beginning (S81) to SLP.SET continuously with the SLP exchange message, carry out thus the location, thereby carry out SUPL POS process (S82).
When stopping SUPL POS process, SET compares the actual position value that arranges in the positional value that calculates and the area event information.According to this relatively, if the positional value that calculates identical with actual position value (that is, zone issue having occured), then SET uses the SUPL report message to send the type (S83) of corresponding positional value and event generation to SLP.
Thus, SLP uses MLP TLREP message to send the positional value (S84) that receives from SET to the SUPL agency.SLP sends the SUPL end to SET and notifies thus SET to finish (termination) SUPL process (or SUPL session) (S85).
In Fig. 4, on the other hand, can omit SUPL and begin the response message with SUPL.In the case, can after sending SUPL POS INIT message, send MLP TLRA message.
Fig. 5 is illustration according to the diagram based on the position fixing process in zone of fifth embodiment of the invention, its illustration compare with the 4th execution mode, based on the relatively long situation of the locating periodically in zone.
As shown in Figure 5, when the position fixing process carried out by long period based on the zone, SLP uses the SUPL end in location (that is, the connection of the SUPL except the SUPL session is released) that ending place in each cycle stops one-period (S100).SLP re-uses subsequently SUPL and triggers message is carried out a rear cycle in the starting point in a rear cycle location (S102).At this, (S90-S99) identical with step (S70-S79) except the step reference number, will no longer repeat its detailed description thus.
That is, when stop one-period based on the position fixing process in zone thus during the generation area event, SLP sends the SUPL end to SET, the SUPLPOS that discharges thus for described one-period connects (S100).After this, SLP uses MLP TLREP message to send corresponding locator value (S101) based on the zone to the SUPL agency.If there is not the generation area event, execution in step (S99 and S101) not so.
Afterwards, in rear one locating periodically based on the zone, SET uses SUPL to begin message to disconnect the SUPL POS that (connections) discharge and connect, and notice SLP will carry out the location (S102) in a rear cycle.In Fig. 5, can omit SUPL and begin the response message with SUPL.In the case, can after having sent SUPL POS INIT message, send MLP TLRA message.SUPL begins message and can replace with SUPL POS INIT message in step S102.
Thus, in rear one locating periodically based on the zone, SLP and SET exchange SUPL POS INIT message, SUPL POS process and SUPL report and MLP TLREP message continuously each other, to carry out the location, in order to send relevant position value (S104-S107) to the SUPL agency.When a series of position fixing process based on the zone stopped, SLP sent the SUPL end to SET, with to the end (termination) of SET notice SUPL process (S108).
Fig. 6 is illustration according to the diagram based on the position fixing process in zone of sixth embodiment of the invention, its illustration SET-triggering situation and the network-startup situation of non-roaming acting server pattern, specifically, its illustration carry out the situation of location by the SET-auxiliary mode.
As shown in Figure 6, identical with the operation of being carried out by the step (S70-S78) of Fig. 4 by the operation that step (S110-S118) is carried out, thus with detailed.
Therefore, when finishing (termination) SUPL POS process (S118), SLP uses the SUPL report message to send the positional value (S119) that calculates to SET.SET compares the actual position value that arranges in the positional value that calculates and the area event information, whether checks thus the generation area event.If be checked through zone issue has occured, SET triggers at SUPL and comprises the positional value that calculates and the trigger event parameter that represents the characteristic of corresponding event in the message so.After this SET sends SUPL to SLP and triggers message (S120).SLP uses MLP TLREP message to send the positional value (S121) that receives from SET to the SUPL agency subsequently.
On the other hand, if be checked through not generation area event, SET periodically carries out following position fixing process so, in the case, and not execution in step S120 and S121.
That is in follow-up locating periodically based on the zone, SET sends SUPLPOS INIT message again to SLP, thus to SLP notice location beginning (S122).SET is used for carrying out the continuous information of actual location subsequently with the SLP exchange, carry out thus SUPL POS process (S123).
When finishing (termination) SUPL POS process, SLP uses the SUPL report message to send the positional value (S124) that calculates to SET.SET compares the actual position value that arranges in the described positional value that calculates and the area event information subsequently, checks thus whether zone issue has occured.If check zone issue has occured, SET triggers the triggering _ event argument that comprises the described positional value that calculates in the message and represent the characteristic of corresponding event at SUPL so, and sends this SUPL triggering message (S125) to SLP.
Therefore, SLP uses MLP TLREP message to send the positional value (S126) that receives from SET to the SUPL agency.SLP sends the SUPL end with backward SET, and SET stops SUPL process (or SUPL session) (S127) with notice.
On the other hand, in Fig. 6, can omit SUPL and begin the response message with SUPL.In the case, after sending SUPL POS INIT message, send MLP TLRA message.
Fig. 7 is illustration according to the diagram based on the position fixing process in zone of seventh embodiment of the invention.The 7th execution mode illustration when SPL can not send reporting standards with SUPL INIT message because of the restriction on the size of SUPL INIT message, SLP sends the embodiment of reporting standards with new SUPL triggering request.
That is, the 7th execution mode of the present invention is different from the 4th execution mode part and is to have increased SUPL trigger request and SUPL and triggers RESPONSE message.Other steps are all identical with step in the 4th execution mode except reference number.
Therefore, when carrying out above-mentioned step (S130-S134), SLP uses the SUPL triggering request to send based on the trigger message of the location in zone (namely to SET, area event information) (S135), in order to make SET according to the location of corresponding information layout based on the zone, and allow SET to carry out independently user's affirmation.After this area event information that the SET storage sends by the SUPL triggering request sends SUPL triggered response message (136) in response to the SUPL triggering request.
Yet different from Fig. 4, as shown in Figure 7, SLP receives the SUPL triggered response message from SET, then sends MLP TLRA message (S137) to the SUPL agency.Because SLP sends the SUPL triggering request that comprises with based on the relevant trigger message in the location in zone to SET, and receive SUPL triggered response message in response to the SUPL triggering request from SET subsequently, therefore only receive the SUPL triggered response message and could notify and sent to SET fully based on the relevant trigger message in the location in zone.Yet the SUPL triggered response message can be omitted, and in the case, SLP sends the SUPL triggering request, and immediately sends MLP TLRA message to the SUPL agency.
SUPL INIT message can send according to the SMS send mode.Therefore, when not comprising the reporting standards parameter fully among the SMS, the SUPL triggering request can represent the message for independent transmission reporting standards parameter, and the SUPL triggered response message is corresponding to the message of response SUPL triggering request.Therefore, in Fig. 4, can omit SUPL and begin message and SUPL response message.Yet, in Fig. 7, for send by the SUPL triggering request with based on the relevant trigger message in the location in zone and receive SUPL and trigger response, for the periodicity location that comprises among the SUPL INIT, SET must at first begin message with the acceptance of acquisition from SLP to SLP transmission SUPL.Therefore, only can omit the SUPL response message.
Even in the 7th execution mode of the present invention, the long period for based on the location in zone also can change process, so that each cycle can disconnect by SET (connection) SUPL session.In the case, before sending SUPL POS INIT message, increase SUPL for each locating periodically and begin message and SUPL response message.If do not use (requirement sends) SUPL report message, after each SUPL POS process, increase the SUPL end so.If use the SUPL report message, increase so the SUPL end in SUPL report message back.
Fig. 5 and 7 illustrations the location (that is, position calculation) by carrying out based on the SET pattern only.If carry out the location by the SET auxiliary mode, as shown in Figure 6, then SLP uses the SUPL report message to send the positional value that calculates to SET, and SET checks whether corresponding event has occured.When corresponding event occured, the SUPL of SET when corresponding event occurs triggered message and notifies SLP.
Fig. 8 is illustration according to the diagram based on the position fixing process in zone of eighth embodiment of the invention, its illustration SET-triggering situation and the SET-of non-roaming acting server pattern start situation.
At first, when SUPL proxy requests during based on the location in zone, be not connected if between SET itself and particular network any data are set, SET connects (S150) from packet data network (for example, 3GPP or 3GPP2) request msg so.
Connect in case data are set, SET sends SUPL to SLP and begins message with the position fixing process (S151) of beginning based on the zone.At this, SET begins to insert in the message (comprising) tlrr_ event argument at SUPL, to arrange based on the characteristic of the location in zone, the relevant information of specific region etc., then sends SUPL to SLP and begins message.
For example, the specific region relevant information can be that the title in zone name in the administration area or known zone is such as " Seoul ", " Shingil 1-dong ".The specific region relevant information is by having lat/lon or coordinate x, and the information of y and z etc. represents.Therefore, SET must send specific region relevant information and/or more specific location information, receives network parameter (for example, cell i d) from SLP thus, and SET distinguishes the respective regions that it moves to by described network parameter.This is why only SLP knows the reason of the cell i d in the zone that configuration is associated with location based on the zone.
Received SUPL and begun whether message SLP use routing iinformation checking SET is current roams (S152) at SUPL.If the current not roaming of SET, SLP begins message to SET transmission SUPL response message (S153) in response to SUPL so.
SLP sends the SUPL response message by comprise the reporting standards parameter in the SUPL response message.SLP comprises the trigger message relevant with the Location Request based on the zone that receives from SET, then described trigger message is sent to SET.That is, SLP transmits the trigger message that produces based on the location in zone to SET, and when occuring with convenient corresponding event (, SET-triggers), allow SET to carry out the actual position fixing process based on the zone.For example, for the location relevant with the specific region, specific region (for example, Seoul or the shingil 1-dong) relevant information that receives from SET is not the expressions such as cell i d of using on the real network.Therefore, SLP changes respective regions into such as cell i d etc. network parameter, after this sends it to SET.In addition, can be responded to send with the agreement that independently provides and SUPL by the value that converts network parameter to that SET distinguishes.
In the locating periodically based on the zone, SET sends SUPL POS INIT message with the position fixing process (S154) of beginning based on the zone to SLP.At this, when having discharged the TCP/IP connection between SET and the SLP after sending the SUPL response message, SET must before send SUPL POSINIT message, reset described data and connect.
SET and SLP exchange continuously for the message of carrying out actual location, carry out thus the SUPLPOS process, thereby calculate the position (S155) of SET.At this, (that is, the SET-auxiliary mode) can be carried out based on the location survey that receives from this SET by SLP in the location (that is, position calculation) that is used for SET, or assists to carry out (that is, based on the SET pattern) by SET based on what obtain from SLP.Fig. 8 illustration the location by carrying out based on the SET pattern.Yet if carry out the location by the SET-auxiliary mode, SLP uses the SUPL report message to send the positional value (S156) that calculates to SET so.
Therefore, SET determines whether the positional value that calculates is identical with the area event information that provides from SLP (for example, cell i d), checks thus whether zone issue has occured.If be checked through zone issue has occured, then SET provides the described positional value that calculates to the SUPL agency.
Afterwards, in follow-up locating periodically, as previously mentioned, SLP and SET use SUPL POSINIT message, SUPL POS process and SUPL report message to carry out the location that is used for respective cycle, in order to calculate the positional value (S157-S159) of SET.When executing a series of position fixing process based on the zone, SLP sends the SUPL end to SET and stops (end) SUPL process (S160) with notice SET.SET discharges all resources relevant with location sessions with the IP connection of SLP and release subsequently.
Fig. 9 is illustration according to the diagram based on the position fixing process in zone of ninth embodiment of the invention, its illustration compare with the 8th execution mode, based on the relatively long situation of the locating periodically in zone.
That is if by the location of long period execution based on the zone, then location-server sends the SUPL end at the end in each cycle to terminal, and stops the location (S176) of one-period.At this, when the location of the location that stops one-period and beginning next cycle, SET use SUPL begin message informing SLP begin second round based on zone location (S177).At this, can comprise since the SUPL message that sends second round having reduced the many like that periodic quantities (for example, number of times) of time value the last week.
Thus, the difference of the 9th execution mode of the present invention and the 8th execution mode is following steps, and wherein after having carried out step S177, SET sends SUPL for each locating periodically to SLP and begins message, begins thus the position fixing process based on the zone.Except above-mentioned steps, the step in the 9th execution mode is all identical except reference number is different from step in the 8th execution mode, no longer repeats thus its detailed description.
As mentioned above, in order to check whether zone issue has occured, must calculate the current location of SET.But, if the position of SET away from the zone of definition in the trigger message (area event information), the periodicity location sessions between SET and the SLP is just so unimportant so.In the case, can come the processing region event by the coarse localization that is used for SET, until SET is near the target area.
Therefore, if use residential quarter-id to carry out coarse localization, basically can dispose with following three phases based on the positioning service in zone so.
1) a plurality of residential quarter-id with the specific region send to SET.
2) a plurality of residential quarter-id of sending are compared with the current residential quarter-id that is positioned of target SET wherein.
3) if one of described a plurality of residential quarter-id are with wherein the current residential quarter-id that is positioned of target SET is identical, then SET periodically begins location sessions.At this, will describe Figure 10 to 13 based on these aspects now.
Figure 10 is illustration according to the diagram based on the position fixing process in zone of tenth embodiment of the invention, its illustration SET-triggering situation and the network-startup situation of non-roaming acting server pattern.The tenth execution mode illustration of the present invention use residential quarter-id carry out approx for the location of SET (namely, and location based on the zone of execution cycle property just when corresponding, the position that defines in the position of after this only working as the SET that calculates and the area event information position calculation).At this, SLP is corresponding to the local network side, and SET is corresponding to end side.
As shown in figure 10, when outside LCS customer requirement during based on the location in zone, the SUPL agency uses MLP TLRR message from the location (S190) of SLP request based on the zone.MLP TLRR message comprises the parameter such as ms-id, clinet-id, QoP, tlrr_ event etc.At this, ms-id represents to carry out the target of location tracking, and QoP represents positional accuracy, and tlrr_ representations of events area event information, namely based on the characteristic of the location in zone and the characteristic of specific region.
The SLP that has received MLP TLRR message uses the checking SET that tables look-up whether to support SUPL, and verifies that this SET is current whether in SUPL roaming (S191).Support SUPL and current not roaming if confirm SET, then SLP sends SUPL INIT message to utilize SET to begin SUPL process (S192) to SET.At this, SUPL INIT message can send according to forms such as WAP Push, SMS triggering, SIP propelling movement, UDP/IP.
SUPL INIT message can comprise the parameter such as session-id, SLP pattern, SUPL pattern, posmethod etc. at least.At this, the operator scheme of SLP modal representation SLP (being acting server pattern or non-proxy server mode), the type of SUPL modal representation location (for example, directly periodically locate the location, based on zone location etc.).In addition, SLP sends SUPL NIT message by the reporting standards parameter is included in the SUPL NIT message.SLP operation report canonical parameter sends the information relevant with the location based on the zone that receives from outside LCS client, i.e. area event information to SET.That is SLP transmits the trigger message that produces based on the location in zone to SET.When corresponding event occurs, allow SET to carry out actual location thus.
When between SET itself and the particular network any data not being set and being connected, the data that the SET that has received SUPL INIT message arranges with packet data network (for example, 3GPP or 3GPP2) connect (S193).
When the data connection was set, the SET storage comprised that by the area event information of SUPL INIT message transmission and to the SLP transmission SUPL triggering of session-id, lid and SET ability information begins message (S194).
Receive SUPL and triggered the SLP that begins message is used for Location Request to SUPL agency transmission by MLP TLRA message affirmation (S195).SLP determines that subsequently which residential quarter belongs to the specific region of being asked by the SUPL agency.The SLP storage is corresponding to the cell i d of determined residential quarter, and use SUPL triggered response message sends cell i d (S196) to SET.
The SET that has received a plurality of cell i d by the SUPL triggered response message is compared described a plurality of residential quarter-id and this SET wherein by the cell i d when prelocalization, whether have the cell i d consistent with the cell i d of SET (S197) to check.Carry out described comparison, to check that by the approximate location (that is, position calculation) that is used for SET whether SET is near the target area.
According to described comparison, if one of a plurality of cell i d are consistent with the cell i d of current SET, then SET confirms it near the target area, and the periodic location based on the zone of beginning.That is SET sends SUPL POS INIT message to SLP in based on the locating periodically in zone, with the position fixing process (S198) of beginning based on the zone.
Therefore, SET and SLP exchange mutually the message that is used for carrying out actual location continuously, carry out thus SUPL POS process, calculate thus the position (S199) of SET.At this, (that is, the SET-auxiliary mode) can be carried out based on the location survey that receives from SET in the location (that is, position calculation) that is used for SET, or assists to carry out (based on the SET pattern) by SET based on what obtain from SLP.Figure 10 illustration the location by carrying out based on the SET pattern.Yet if carry out the location by the SET auxiliary mode, SLP uses the SUPL report message to send the positional value (S200) that calculates to SET.
When obtaining the positional value of SET, the actual position value that arranges in the positional value that SET will obtain and the area event information is compared, and whether inspection zone issue has occured.Do not have the generation area event if be checked through, then again execution in step S201 and S202 to calculate new positional value.At this, if carry out the location by the SET auxiliary mode, then SLP uses the SUPL report message to send the positional value (S203) that calculates to SET.
Afterwards, the actual position value that arranges in the positional value that again latest computed gone out of SET and the area event information compares.If two positional values are consistent thereby zone issue (S204) occured mutually, then SET uses the SUPL report message to send positional value (that is, locator value) that described latest computed goes out (S205) to SLP.Thus, SLP sends the SUPL end to stop SUPL session (S206) to SET.SLP uses MLP TLREP message to send the locator value (S207) that receives from SET to the SUPL agency subsequently.
Figure 11 is illustration according to the diagram based on the position fixing process in zone of eleventh embodiment of the invention, its illustration SET-triggering situation and the network-startup situation of non-roaming acting server pattern.The 11 execution mode illustration of the present invention SLP calculate to be used for initial period information based on the location in zone, to send the initial period information of being calculated to SET, and SET is according to described initial period information and executing location, and after this position according to SET changes initial period information.
As shown in figure 11, identical with the operation of carrying out by the step S190 to S193 among Figure 10 by the operation that step S210 to S213 carries out, no longer repeat thus detailed description thereof.
Connect (S213) in case data are set, the area event information that SUPL INIT message sends is passed through in the SET storage, and comprises that to the SLP transmission SUPL of session-id, lid and SET ability information triggers beginning message (S214).
Receive the SLP that SUPL triggers beginning message, sent the affirmation (S215) that is used for Location Request by utilizing MLP TLRA message to the SUPL agency.SLP calculates subsequently by the relative distance between the specific region of SUPL proxy requests and the current location of SET (namely using the position of lid approximate evaluation).SLP calculates initial period based on the location in zone based on the relative distance of calculating thus.The initial period that calculates is sent to SET (S216) by the SUPL response message.Lid represents place (position) identifier.
The SET that has received based on initial period of the location in zone by the SUPL response message begins cycle location sessions (S217).SET sends SUPL POSINIT message with the position fixing process (S218) of beginning based on the zone in the corresponding initial period to SLP.
Therefore, SET and SLP exchange continuously and are used for carrying out the message of actual location to carry out SUPLPOS process, the position (S219) of calculating thus SET.At this, (SET-auxiliary mode) can be carried out based on the location survey that receives from SET by SLP in the location (that is, position calculation) that is used for SET, or assists to carry out (based on the SET pattern) by SET based on what obtain from SLP.Figure 10 illustration the location by carrying out based on the SET pattern.Yet if carry out the location by the SET auxiliary mode, SLP uses the SUPL report message to send the positional value (S220) that calculates to SET.
When having calculated the calculated location value of SET, SET compares the actual position value that arranges in the positional value that calculates and the area event information, to check whether zone issue has occured.If be checked through not generation area event, then SET recomputates the relative distance between the positional value that calculates and the zone of asking, and changes thus the cycle (S221) based on the location in zone.
Afterwards, in the cycle based on the location in zone, SET sends SUPLPOS INIT message to SLP in latest computed.At this, the locating periodically of change is sent to SLP (S222).Therefore, SET and SLP exchange continuously and are used for carrying out the information of actual location to carry out SUPL POS process, the position (S223) of calculating thus SET.At this, if carry out the location by the SET auxiliary mode, then SLP comes to send the positional value (S224) that calculates to SET with the SUPL report message.
Afterwards, SET compares the actual position value that arranges in the positional value of latest computed and the area event information again.If two positional values are consistent with each other and therefore generation area event (S225), then SET utilizes the SUPL report message to send described reposition value (S226) to SLP.SLP sends the SUPL end to stop SUPL session (S227) with backward SET.After this, SLP uses MLP TLREP message to send the described positional value (S228) that receives from SET to the SUPL agency.
Figure 12 is illustration according to the diagram based on the position fixing process in zone of twelveth embodiment of the invention, its illustration SET-triggering situation and the SET-of non-roaming acting server pattern start situation.Identical with the tenth execution mode, the 12 execution mode illustration of the present invention following situation: use residential quarter-id to carry out the approximate location that is used for SET, after this location based on the zone of ability execution cycle property when the position that defines in the calculating location of SET and the area event information is corresponding only.
As shown in figure 12, when SUPL proxy requests during based on the location in zone, be not connected if between SET itself and particular network any data are set, then SET arranges and is connected (S230) with the data of packet data network.
Connect in case data are set, SET sends SUPL to SLP and triggers beginning message with the position fixing process (S231) of beginning based on the zone so.At this, SET triggers in the beginning message at SUPL and comprises the tlrr_ event argument, to arrange based on the type of the location in zone and the relevant information of specific region.SET sends message with backward SLP.
The SLP that has received SUPL triggering beginning message determines which residential quarter belongs to the specific region.Then, the cell i d that the SLP storage is corresponding with respective cell, and use the SUPL triggered response message to send cell i d (S232) to SET.By the SUPL triggered response message received the SET of a plurality of cell i d will be wherein the current cell i d that is positioned of SET compare with a plurality of cell i d that receive, whether inspection exists the cell i d consistent with the cell i d of SET (S233) thus.Carry out this comparison and check that with the approximate location by SET whether SET is near the target area.
If one of a plurality of cell i d are consistent with current area id, then SET confirms it near the target area, then begins periodic location based on the zone.That is in the locating periodically based on the zone, SET sends SUPL POS INIT message with the position fixing process (S234) of beginning based on the zone to SLP.
Therefore, SET and SLP exchange continuously and are used for carrying out the message of actual location to carry out SUPLPOS process, the position (S235) of calculating thus SET.At this, (that is, the SET-auxiliary mode) can be carried out based on the location survey that receives from SET by SLP in the location (that is, position calculation) that is used for this SET, or assists to carry out (that is, based on the SET pattern) by SET based on what obtain from SLP.Figure 12 illustration the location by carrying out based on the SET pattern.Yet if carry out the location by the SET-auxiliary mode, SLP sends the positional value (S236) that calculates with the SUPL report message to SET.
When obtaining the positional value of SET, the actual position value that arranges in the positional value that SET will obtain and the area event information is compared, and whether inspection zone issue has occured thus.If be checked through not generation area event, then re-execute step S237 and S238 to calculate new positional value.At this, if carry out the location by the SET-auxiliary mode, then SLP uses the SUPL report message to send the positional value (S239) that calculates to SET.
Afterwards, SET re-starts comparison with the actual position value that arranges in the positional value of latest computed and the area event information.If two positional values are consistent with each other and therefore generation area event (S240), then SET uses the SUPL report message to send described new positional value (S241) to SLP.SLP sends the SUPL end to finish (termination) SUPL session (S242) to SET.
Figure 13 is illustration according to the diagram based on the position fixing process in zone of thirteenth embodiment of the invention, its illustration SET-triggering situation and the SET-of non-roaming acting server pattern start situation.As the 11 execution mode, the 13 execution mode illustration of the present invention following situation: SLP calculate to be used for initial period information based on the location in zone, so that described information is sent to SET, and SET changes initial period information according to described initial period information and executing location with the position according to SET.
As shown in figure 13, when SUPL proxy requests during based on the location in zone, be not connected if between SET itself and particular network any data are set, then SET arranges and is connected (S250) with the data of packet data network.When the data connection was set, SET sent SUPL to SLP and triggers beginning message, with the position fixing process (S251) of beginning based on the zone.At this, SET triggers in the beginning message at SUPL and comprises the tlrr_ event argument, so that characteristic and the specific region relevant information based on the location in zone to be set.SET sends message with backward SLP.
Receive SUPL and triggered the SLP calculating of STAT message by the relative distance between the specific region of SUPL proxy requests and the current location of SET (that is the position of, using lid to estimate approx).SLP calculates initial period based on the location in zone based on the relative distance that calculates.Use the SUPL response message that the initial period that calculates is sent to SET (S252).
The SET that has received based on initial period of the location in zone uses the SUPL response message to begin cycle location sessions (S253).SET sends SUPL POS INIT message with the position fixing process (S254) of beginning based on the zone to SLP subsequently in the initial period of corresponding location.
Therefore, SET and SLP continuously exchange are used for carrying out the information of actual location, in order to carry out SUPL POS process, the position (S255) of calculating thus SET.At this, (that is, the SET-auxiliary mode) can be carried out based on the location survey that receives from SET by SLP in the location of SET, or assists to carry out (that is, based on the SET pattern) by SET based on what obtain from SLP.Figure 10 illustration the location by carrying out based on the SET pattern.Yet if carry out the location by the SET-auxiliary mode, SLP uses the SUPL report message to send the positional value (S256) that calculates to SET.
When having calculated the calculated location value of SET, SET compares the actual position value that arranges in the positional value that calculates and the area event information, to check whether zone issue has occured.If be checked through not generation area event, then SET recomputates the relative distance between the positional value that calculates and request zone, changes thus the cycle (S257) that is used for based on the location in zone.
Afterwards, in the cycle that is used for based on the latest computed of zone location, SET sends SUPL POS INIT message with the position fixing process of beginning based on the zone to SLP.At this, the locating periodically of change is sent to SLP (S258).Thus, SET and SLP continuously exchange are used for carrying out the message of actual location, in order to carry out SUPL POS process, the position (S259) of calculating thus SET.At this, if carry out the location by the SET-auxiliary mode, then SLP uses the SUPL report message to send the positional value (S260) that calculates to SET.
Then, the actual position value that arranges in SET positional value that this latest computed is gone out and the area event information re-starts comparison.If two positional values are consistent with each other and therefore generation area event (S261), then SET uses the SUPL report message to send new positional value (S262) to SLP.SLP sends the SUPL end to stop SUPL session (S263) to SET.
As mentioned above, the first to 13 execution mode of the present invention has illustrated and the situation of Periodic correlation connection ground execution based on the location in zone.Yet, always do not carry out with Periodic correlation connection ground based on the location in zone.That is, only when the actual position value that arranges in the positional value of SET and the area event information is consistent, (that is, only when when prestoring trigger message generation corresponding event) can carry out the location based on the zone.Figure 14 to 16 illustration various types of location based on the zone of irrespectively carrying out with specific period.
Figure 14 is illustration according to the diagram based on the position fixing process in zone of fourteenth embodiment of the invention, its illustration SET-triggering situation and the network-startup situation of non-roaming acting server pattern.
When outside LCS customer requirement during based on the location in zone, the SUPL agency uses MLP TLRR message from the location (S270) of SLP request based on the zone.MLP TLRR message can comprise the parameter such as ms-id, client-id, QoP, tlrr_ event etc.
The SLP that has received MLP TLRR message uses the checking SET that tables look-up whether to support SUPL, then uses routing iinformation to verify that this SET is current whether in SUPL roaming (S271).Support SUPL and current not roaming if confirm SET, SLP sends SUPL INIT message to SET so, begins SUPL process (S272) to utilize SET.At this, SUPL INIT message can send according to forms such as WAP Push, SMS triggering, SIP propelling movement, UDP/IP.
SUPL INIT message can comprise the parameter such as session-id, posmethod, reporting standards, SLP pattern, SUPL pattern etc. at least.At this, the operator scheme of SLP modal representation SLP.SUPL modal representation align_type.Before execution in step S271, SLP can verify the privacy of SET.If customer requirements relates to the notice of place (position) information, then SLP also can comprise notifying parameters in MLP TLRR message.
In addition, SLP comprises the reporting standards parameter in SUPL INIT message, to send SUPLINIT message.SLP operation report canonical parameter sends the trigger message relevant with the location based on the zone that receives from outside LCS client, i.e. area event information to SET.That is SLP transmits the trigger message (that is, SET-triggering situation) that produces based on the location in zone to SET.So, when corresponding event occurs, allow SET to carry out actual location.
For example, for the location based on the zone, SLP comprises that in particular message sign based on the parameter of the characteristic of the location in zone and specific region, sends described particular message thus.At this, such as the title of the specific region of " Seoul " or " Shingil 1-dong ", for example expression is used for the parameter whether the inquiry user accepts this location when SET user moves on to respective regions, this parameter with private examine relevant.
Yet, for the location based on the zone, use MLP TLRR message in fact not represent the cell i d on the network from the specific region relevant information (for example, Seoul or Shingil 1-dong) that the SUPL agency has sent.Thus, SLP changes the specific region into such as cell i d etc. network parameter to send thus described network parameter.In addition, SLP use SUPL INIT message sends the title of specific region same as before, that is, and and the title of the specific region that use MLP TLRR message has sent.The value of the network parameter (that is, cell i d) that is converted to SET and can distinguishes also can be provided by the agreement that independently provides SLP.
When between SET itself and the particular network any data not being set and being connected, the SET that has received SUPL INIT message arranges and is connected (S273) with the data of packet data network.When data network was set, the SET storage was by the trigger message of SUPL INIT message sink, and this backward SLP sends SUPL and begins message (S274).
For corresponding Location Request, SLP confirms (that is, whether this location can carry out) (S275) by using MLP TLRA message to send to the SUPL agency.SLP begins message in response to SUPL subsequently and sends SUPL response message (S276) to SET.At this, when by using title that SUPL INIT message sends the specific region that sends by MLP TLRR message same as before (namely, the title of being distinguished by the user) time, SLP uses the SUPL response message to send the value that changes the network parameter (for example, cell i d or shape information) that SET can distinguish into to SET.
Afterwards, SET verifies that cell i d that SET itself wherein is positioned is whether consistent with the cell i d that comprises in the trigger message, and checks thus whether zone issue has occured.If it is consistent and therefore the generation area event is (namely to be checked through the cell i d that comprises in cell i d that SET wherein is positioned and the trigger message, if SET moves on to the zone that defines in the area event information), then SET sends SUPL POS INIT message with beginning position fixing process (S277) to SLP.At this, if after sending the SUPL response message, SET is connected with TCP/IP between the SLP and disconnects, and then SET must reset described data connection before sending SUPL POS INIT message.
SLP and SET exchange the message that is used for carrying out actual location continuously.SLP and SET calculate the position (S278) of SET subsequently by this continuous message.(being the SET-auxiliary mode) can be carried out based on the location survey that receives from SET by SLP in the location (being that calculate the position) that is used for this SET, or assists to carry out (namely based on the SET pattern) by SET based on what obtain from SLP.If by carrying out the location based on the SET pattern, then SET uses the SUPL report message to send the positional value (S279) that calculates to SLP.
Therefore, SLP uses MLP TLREP message to send the positional value that is calculated by SLP itself or the positional value (S280) that receives from SET to the SUPL agency.
SUPL among Figure 14 begins can omit with the SUPL response message.In the case, can after sending SUPL POS INIT message, send MLP TLRA message.Yet, the name that sends the specific region when the SLP former state is referred to as the specific region relevant information in the SUPL INIT message, and when comprising that in the SUPL response message the value that converts network parameter (being cell i d or shape information) to that SET can distinguish sends described value, can not omit the SUPL response message.
Figure 15 is illustration according to the diagram based on the position fixing process in zone of fifteenth embodiment of the invention, its illustration SET-triggering situation and the network-startup situation of non-roaming acting server pattern.The 15 execution mode illustration when because the restriction of the size of SUPL INIT message, when SLP can not use SUPL INIT message to send reporting standards, SLP sent the situation of reporting standards with new SUPL triggering request.Therefore, the 15 execution mode is most of similar with the 14 execution mode, except having increased SUPL trigger request and SUPL triggered response message.
At first, when carry out being used for beginning based on the step (S290-S294) of the location in zone, SLP use the SUPL triggering request to SET send with based on the relevant information in the location in zone (S295), in order to make SET according to the location of corresponding information layout based on the zone, and allow SET independently to carry out user's affirmation.After this SET storage sends SUPL triggered response message (S296) in response to the SUPL triggering request by the area event information that the SUPL triggering request sends.
But different from the 14 execution mode, the SLP in the 15 execution mode receives the SUPL triggered response message from SET, then sends MLP TLRA message (S297) to the SUPL agency.Execution in step S297 as follows, namely since SLP by in the SUPL trigger request, comprising and sending described SUPL triggering request based on the relevant trigger message in the location in zone to SET, and in response to the SUPL triggering request, reception is from the SUPL triggered response message of SET, so only in SLP, receive after the SUPL triggered response message, could identify and sent to SET fully based on the relevant trigger message in the location in zone.Yet, also can omit the SUPL triggered response message.In the case, SLP sends the SUPL triggering request and sends MLP TLRA message to the SUPL agency immediately.
SUPL INIT message can send according to the SMS send mode.Therefore, when not comprising whole reporting standards parameter among the SMS, the SUPL triggering request can represent the message for independent transmission reporting standards parameter, and the SUPL triggered response message is corresponding to the message of response SUPL triggering request.
Independent to send by the name translation with the specific region be the discernible network parameter of SET (for example, cell i d or shape information) and the value that obtains then can send by analog value being included in the SUPL trigger request information if need.The name that in addition, can send same as before the specific region that sends by MLP TLRR message in the SUPL triggering request is referred to as the specific region relevant information.Also can be included in the SUPL response message by the value (for example, cell i d or shape information) that will be converted to the discernible network parameter of SET and send.
Therefore, in Figure 14, can omit SUPL and begin message and SUPL response message.Yet, in Figure 15, if by using the SUPL triggering request to send and also receiving subsequently the SUPL triggered response message based on the relevant trigger message in the location in zone, then SET at first begins message to SLP transmission SUPL and obtains SLP for the acceptance based on the location in zone that is included in the SUPL INIT message.Therefore, can only omit the SUPL response message.Yet, using SUPL triggering request former state to send the specific region relevant information (namely, the title of the specific region that sends by MLP TLRR message) in the situation, and send by the SUPL response message by the name translation with the specific region be the value that obtains of network parameter (for example, cell i d or shape information) situation under, can not omit the SUPL response message.
Subsequent step (S298-S302) is identical with step (S276-S284), therefore no longer repeats its detailed description.
Figure 16 is illustration according to the diagram based on the position fixing process in zone of sixteenth embodiment of the invention, its illustration SET-triggering situation and the SET-of non-roaming acting server pattern start situation.
As shown in figure 16, when SUPL proxy requests during based on the location in zone, be not connected if between SET itself and particular network any data are set, then SET connects (S310) from the packet data network request msg.
When the data connection was set, SET sent SUPL to SLP and begins message with the location (S311) of request based on the zone.At this, SET begins to comprise in the message (insertion) tlrr_ event argument at SUPL, and the parameter with the characteristic that is provided for identifying location based on the zone, specific region etc. sends message to SLP thus.Specifically, for the location based on the zone, SET comes to send the tlrr_ event argument to SLP by representing therein the specific region, in order to receive the network parameter that in fact SET itself can not identify from SLP.For example, the information (for example, Seoul or Shingil 1-dong) that the specific region that in fact sends of terminal is relevant can be the title in the zone in the administrative region or the title in known zone.Described respective name can not be expressed as the cell i d on the real network.
Therefore, SET must send the specific region relevant information to SLP, so that SLP is converted to the network parameter that can move on in order to identify SET itself the cell i d of respective regions such as SET with the specific region relevant information, thus to the network parameter of SET transmission through conversion.In addition, in order to receive the cell i d that in movement, has moved on to the described respective regions of respective regions so as to identification terminal, the information relevant with the lat/lon of specific region has lat/lon or coordinate x to send thus even SET knows for sure, the respective regions relevant information of y and z, SET also must send exact position (zone) information to SLP, receives subsequently the cell i d of respective regions from SLP.This is because only have SLP to know the cell i d that consists of with based on the relevant zone of zone location.
Having received the SLP that SUPL begins message uses routing iinformation checking SET current whether in SUPL roaming (S312).If the current not roaming of SET, then SLP begins message to SET transmission SUPL response message (S313) in response to SUPL.
SLP is by comprising that the mode of reporting standards parameter sends the SUPL response message in the SUPL response.By comprising that in described parameter the area event information relevant with the Location Request based on the zone that receives from SET sends described parameter to described SET.Be that SLP transmits the trigger message that produces based on the location in zone to SET, when the corresponding event generation occurs, in SET, carry out actual position fixing process in order to allow.Specifically, for the location based on the zone, use MLPTLRR message in fact not to be expressed as the cell i d on the network from the specific region relevant information (for example, Seoul or Shingil 1-dong) that the SUPL agency sends.Thus, SLP changes the specific region into such as cell i d etc. network parameter, and this backward SET sends described cell i d.SLP also uses SUPL INIT message former state to send the specific region title that is sent by MLP TLRR message.The value that changes the network parameter (for example, cell i d) that SET can distinguish into can send by the agreement that provides independently.
After this, when concrete event (that is, when SET moves on in the respective regions) occured the trigger message based on storage, SET sent SUPL POS INIT message with the position fixing process (S314) of beginning based on the zone to SLP.At this, SET can be with representing that the event trigger parameters that event occurs notifies SLP.At this, if after sending the SUPL response message, the TCP/IP connection between SET and the SLP discharges, and then before sending SUPL POS INIT message, SET must reset this data and connect.
Therefore, SET and SLP exchange continuously and are used for carrying out the message of actual location to calculate the position (S315) of SET.At this, (being the SET-auxiliary mode) can be carried out based on the location survey that receives from SET by SLP in the location (being that calculate the position) that is used for this SET, or carries out based on assisting of obtaining from SLP by SET.Figure 16 illustration the location by carrying out based on the SET pattern.Yet if carry out the location by the SET-auxiliary mode, SLP uses the SUPL report message to send the positional value (S316) that calculates to SET.
Figure 17 is illustration according to the diagram based on the position fixing process in zone of first embodiment of the invention, its illustration be used for SET-triggering situation and the network-startup situation of SET-auxiliary mode.
As shown in figure 17, when outside LCS client requests during based on the location in zone, the SUPL agency sends MLP TLRR message (S320) to SLP.
MLP TLRR message can comprise such as ms-id, client-id, QoP, the parameter of tlrr_ event etc., ms-id represents target SET, QoP represents that positional accuracy (for example, time delay and spatial precision), and the relevant trigger parameter in tlrr_ representations of events location, it represents for example relevant with the location various conditional informations, such as based on the characteristic of zone location (for example, whether target SET (for example terminal) moves on in the specific region or shifts out the specific region, and be arranged in the specific region) and the characteristic of specific region is (for example, the title of specific region, exact position value etc.).
MLP TLRR message also can comprise the parameter relevant with the type of locator value (its expression currency or the value that obtains in the recently time), and the parameter that is used for arranging with respect to each Location Request of several Location Requests priority.
The SLP that has received MLP TLRR message verifies with look-up table whether this target SET supports SUPL, then uses routing iinformation to verify that this target SET is current whether in SUPL roaming (S321).
Support SUPL and current not roaming if confirm this SET, then SLP sends SUPL startup (SUPL INIT) message to SET, begins SUPL process (S322) to utilize SET.At this, SUPL INIT message is such as sending according to forms such as WAP (wireless application protocol) (WAP) propelling movement, Short Message Service (SMS) triggering, session initiation protocol (SIP) propelling movement, UDP/IP.
SUPL INIT message can comprise at least session-id, triggers type indicator (for example, zone issue), SLP pattern (that is, acting server pattern or non-proxy server mode), localization method (posmethod) to be used etc.In addition, before execution in step S321, SLP confirms the privacy of SET.If the user need to relate to the notice of place (position) information, then SLP also comprises notifying parameters in SUPL INIT message.
Therefore, SLP is by comprising that in SUPL INIT triggering type parameter sends SUPL INIT message.These parameters can be used to ask to carry out corresponding location (that is, network-triggering situation) based on the location in zone and by SLP to the SET notice.
The SET that has received SUPL INIT message identifies SLP and uses acting server pattern and setting to be connected with the safe IP of SLP.When between SET itself and the particular network any data not being set and being connected, the data that SET arranges with packet data network (that is, 3GPP or 3GPP2) connect (S323).Connect in case data are set, SET sends SUPL to SLP and begins message with beginning zone issue triggering session (S324).At this, SUPL triggers beginning message can comprise session-id, lid and SET ability information at least.
When receiving SUPL triggering beginning message, SLP is chosen in the localization method that will use in the zone issue triggering session, and sends the SUPL triggered response message (S325) that comprises session-id, posmethod and trigger parameter (triggering params) to SET.This trigger parameter represents the area event trigger parameters relevant with the location.This trigger parameter is to trigger the part of relevant parameter with zone issue.
For example, this trigger parameter can comprise the characteristic of zone issue and the trigger condition information of expression specific region.The characteristic of this zone issue can be used for representing whether SET moves on in the specific region or shift out the specific region, or is arranged in the specific region.Simultaneously, the SUPL triggered response message can comprise the location identifier (position id) for the specific region of zone issue triggering session.Preferably, this position id can represent the information in the physical location zone on the indication network, such as cell i d, MCC, MNC or the LAC or the scrambling code number that belong to SUPL agency and asked the zone of locating.Specifically, for WCDMA, position id represents main scrambling code number.
In addition, SLP uses MLP TLRA message to the acceptance (S326) of SUPL agent advertisement Location Request.
For by SUPL triggered response message receiving position id, only when satisfying trigger condition, Cai SET sends SUPL POS INIT message to SLP.
For example, compare to verify whether satisfy trigger condition by the position id with current SET with the position id that receives from SLP.That is, SET wherein SET is compared with a plurality of cell i d that received by the cell i d when prelocalization, checks thus whether have the cell i d identical with its cell i d.
Represent that SET moves in the specific region or is arranged in the specific region if be included in the characteristic of the zone issue in this trigger parameter, then SET only when at least one of the position id that receives from SLP is consistent with the position id of SET, just begins periodicity and locates.On the contrary, if the characteristic of this zone issue represents that SET shifts out the specific region, when then only working as any position id that receives and not being equal to the position id of SET, SET just begins periodically location.
Carry out described comparison with the approximate location by SET, check whether SET moves closer to the zone of being asked by the SUPL agency.
If the audit by comparison by position id is to having satisfied trigger condition, then SET identifies SET itself and has moved closer to the zone of asking, and sends SUPL POS INIT message with beginning location sessions (S327) with backward SLP.SUPL POS INIT message can comprise session id and location identifier (lid) at least.
SLP and SET exchange the message that is used for carrying out actual location continuously, to calculate the position (S328) of SET.Preferably, the message that exchanges between SLP and SET can comprise session id, be ready to use in the agreement of location (for example, RRLP, RRC or TIA-801) etc.(being the SET-auxiliary mode) can be carried out based on the location survey that receives from SET by SLP in the location (being that calculate the position) that is used for SET, or based on assisting to carry out (namely based on the SET pattern) by SET based on what obtain from SLP.In this embodiment, carry out the location by the SET-auxiliary mode, SLP comes to send the positional value (that is, posresult) (S329) that calculates to SET by the SUPL report message thus.If carry out the location by the pattern based on SET, then do not need the SUPL report message.
Therefore, when the positional value (being posresult) that receives from the SET of SLP, SET compares the positional value of the specific region that defines in the positional value that calculates and the trigger parameter, in order to check whether satisfy trigger condition, whether zone issue (S330) has occured namely.
According to described comparison, if the positional value that defines in the positional value of SET and the trigger parameter consistent (that is, if zone issue occurs), then SET carries out the operation (S335) that continues next step.If two values are inconsistent each other, then SET sends SUPL POS INIT message to SLP, with the beginning (S331) of again notifying the SLP location sessions.After this, SLP and SET continuously exchange are used for carrying out the message of actual location, calculating the position (S332) of SET, and send the positional value (being posresult) that calculates (S333) by the SUPL report message to SET.
When the positional value (posresult) that receives from the SET of SLP, SET compares the positional value of the specific region that defines in this positional value that calculates and the trigger parameter, with the inspection area event whether (S334) occurs.According to this relatively, if there is not the generation area event, then SET repeatedly carries out the step identical with step (S21-S23).If mutually the same, then SET sends SUPL report message (S335) to SLP.The SUPL report message can comprise the positional value (being posresult) of session id and generation area event at least.
Thus, SLP sends locator value (S336) based on the zone by MLP TLREP message to SUPL agency, and sends the SUPL end with the end (termination) of notice SET location sessions (S337) to SET.The SET that has received the SUPL end discharges all resources relevant with location sessions with the IP connection of SLP and release.
Figure 18 is illustration according to the diagram based on the position fixing process in zone of second embodiment of the invention, its illustration SET-triggering situation and the SET-of non-roaming acting server pattern start situation.
As shown in figure 18, when the SUPL proxy requests zone issue among the SET triggers service, be not connected if between SET itself and particular network any data are set, then the SET setting is connected (S340) with the data of packet data network.
In the situation that is provided with this data connection, SET uses the default address setting that provides from local network to be connected with the safe IP of H-SLP.Then, SET sends SUPL to SLP and triggers beginning message with beginning location sessions (S341).SUPL trigger beginning message can comprise at least session id, trigger type indicator (for example zone issue), lid, SET ability and trigger parameter (trigger _ params).
This trigger parameter represents the area event trigger parameters relevant with the location.This trigger parameter is the part about the parameter of zone issue triggering.
This trigger parameter can comprise several trigger condition information, for example characteristic of zone issue and specific region.The characteristic of this zone issue can comprise several conditional informations, and described conditional information represents that whether SET moves on in the specific region or shift out the specific region, perhaps is arranged in the specific region.
The SLP that has received SUPL triggering beginning message determines which residential quarter belongs to the specific region in the trigger parameter.SLP stores the location identifier (position id) of respective regions subsequently, and sends this position id (S342) by the SUPL triggered response message to SET.Preferably, the information that this position id can represent the physical location zone on the indication network (for example, belong to cell i d, mobile country code (MCC), mobile network code, MNC (MNC), location area code (LAC etc.) that SUPL agency has asked the zone of locating, or scrambling code number.Specifically, for WCDMA, position id is corresponding to main scrambling code number.
The SET that has received this position id by the SUPL triggered response message sends SUPL POS INIT message when satisfying trigger conditions.That is, SET is with the position id of current SET compare with the position id that receives (S343).For example, SET wherein this SET is compared with a plurality of cell i d that received as the cell i d of prelocalization, and whether inspection exists the identical cell i d of cell i d that is positioned with this SET wherein thus.
Represent that SET moves in the specific region or is arranged in the specific region if be included in the characteristic of the zone issue in the trigger parameter, then SET only when at least one of the position id that receives from SLP is equal to the position id of this SET, just begins periodically to locate.On the contrary, if the characteristic of this zone issue represents that SET shifts out the specific region, then SET only when any position id that receives is not equal to the position id of this SET, just begins periodically location.Carry out this comparison, with the approximate location by SET, check whether SET moves closer to the zone by the SUPL proxy requests.
According to this relatively, if at least one among the position id that receives is equal to the current location id of SET, then SET identifies SET itself near this request zone, and sends SUPLPOS INIT message with beginning location sessions (S344) with backward SLP.SUPL POS INIT message can comprise session id and location identifier (lid) at least.
SLP and SET exchange the message that is used for carrying out actual location continuously, to calculate the position (S345) of SET.At this, (being the SET-auxiliary mode) can be carried out based on the location survey that receives from SET by SLP in the location (being that calculate the position) that is used for this SET, or assists to carry out (namely based on the SET pattern) by SET based on what obtain from SLP.In the execution mode of Figure 18, carry out the location by the pattern based on SET.Yet if carry out this location by the SET-auxiliary mode, SET sends the positional value (S346) that calculates by the SUPL report message to SET.
In the situation of the positional value that has calculated SET, SET compares the positional value of the specific region that defines in the positional value that calculates and the trigger parameter, in order to check whether satisfy trigger condition, namely whether zone issue (S347) occurs.According to this relatively, if trigger condition is not satisfied, then SET calculates the reposition value by execution in step S348 and S349.At this, if carry out this location by the SET-auxiliary mode, then SLP uses the SUPL report message to send this positional value that calculates (S350) to SET.
In the situation of having calculated the reposition value, the positional value of the specific region that defines in the positional value that SET will newly calculate and the trigger parameter is compared, and whether (namely generation area event) (S351) in order to check and whether satisfy trigger condition.If trigger condition is satisfied, then SET sends SUPL end (S352) to the positional value of the described latest computed of inner proxy-reporting with backward SLP.
As mentioned above, the present invention proposes a kind of method of in based on the localization method of SUPL, carrying out based on the location in zone, in order to allow to carry out the various localization methods based on SUPL.
In the situation that does not break away from spirit of the present invention or inner characteristic, the present invention can be embodied as several form, should also be appreciated that, above-mentioned execution mode is not limited by any details of foregoing description, unless otherwise mentioned, otherwise broadly explain in its spirit and scope that should in claims, define, therefore, be intended to comprise whole variations and modification in the equivalent in the boundary that falls into claims and the scope or that fall into this boundary and scope by claims.
