Description

A kind of method of portable terminal being carried out triggered location

Technical field

The present invention relates to mobile positioning technique, particularly relate to a kind of method of portable terminal being carried out triggered location.

Background technology

The mobile communication location service is by certain technology, obtain target terminal position information, and positional information is used for many aspects such as emergency relief, automobile navigation and intelligent transportation system, scheduling and Team Management, mobile yellow pages inquiry, enhancing network performance.

In some applications, initiate client based on the location in running fix (SUPL, the Safe User PlaneLocation) system of secure user plane and need carry out triggered location target terminal.Triggered location comprises cycle triggered location and area triggering positioning.In the cycle triggered location, the location is initiated client and is being submitted to ownership SUPL locating platform (H-SLP, Home SUPL Location Platform) specifies the zero hour, the finish time and the cycle of location in the triggered location request, wherein can replace with the duration finish time.Positioning interaction between H-SLP and the target terminal is periodically initiated, and initiates the clients report target terminal position to the location after obtaining target terminal position at every turn.In area triggering positioning, client is specified the monitored object terminal location in the triggered location request of submitting to H-SLP the zero hour and area triggering condition initiated in the location, determines by H-SLP or target terminal which the positioning interaction between them initiated constantly at; Positioning interaction all obtains target terminal position one time each time, initiates the area triggering condition that client proposes if the target terminal position that gets access to meets the location in the triggered location request, then initiates the clients report target terminal position to the location.

In triggered location, can judge whether the triggered location condition satisfies and then whether decision initiates positioning interaction, and just trigger is positioned at H-SLP by H-SLP; Also can judge whether the triggered location condition satisfies and then whether decision initiates positioning interaction, and just trigger is positioned at target terminal by target terminal.In view of the above, can orientation triggering be divided into network-triggered and terminal triggering from another angle.

In the prior art, no matter be in the cycle triggered location or in area triggering positioning, still be that the terminal triggered location is mutual no matter also by the network-triggered positioning interaction, when the positioning interaction that carries out at each H-SLP and target terminal begins, target terminal all need and H-SLP between set up Internet protocol (IP, Internet Protocol) and connect; After each positioning interaction finished, target terminal was connected with the IP that H-SLP can discharge each other, and discharges all resources relevant with this location sessions.Especially, for network-triggered, when the positioning interaction that carries out at each H-SLP and target terminal begins, H-SLP also needs at first by Short Message Service (SMS, Short Message Service) or WAP (wireless access protocol) (WAP, Wireless Access Protocol) the relatively poor mode of this real-time issues the location initial message to target terminal, and target terminal just can begin to set up IP with H-SLP and is connected then.

The shortcoming of prior art is that on the one hand, if the time interval between the positioning interaction is very short, this each positioning interaction all needs to rebulid the IP ways of connecting when beginning, and its joint efficiency is very low; Especially, for network-triggered, when positioning interaction began next time, H-SLP also had to issue the location initial message by non real-time SMS or WAP mode, has reduced location efficiency.On the other hand, if target terminal keeps IP to be connected with H-SLP all the time, though can raise the efficiency, but it is longer for the triggered location mission duration, and the situation that the interval between per twice positioning interaction in the triggered location task is also all long, target terminal keeps IP to be connected the load that can increase both sides greatly with H-SLP for a long time, waste system resource.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of portable terminal is carried out the method for triggered location, has both improved joint efficiency and location efficiency, the system resource of avoid waste again H-SLP and target terminal.

Fig. 2 is the flow chart that portable terminal is carried out trigger positioning method embodiment two provided by the invention.

Embodiment

Core concept of the present invention is: in triggered location, H-SLP and target terminal carry out repeatedly positioning interaction if desired, then after initial phase finishes and after each positioning interaction end, determine whether need to keep H-SLP to be connected with current IP between target terminal earlier, then H-SLP keeps current IP to be connected with target terminal if desired.

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with drawings and the specific embodiments.

The difference of cycle triggered location and area triggering positioning is: the positioning interaction time started of cycle triggered location is initiated the client appointment by the location, and the positioning interaction time started of area triggering positioning is determined as required by H-SLP or target terminal; The cycle triggered location all can initiate client for the location target terminal position message that positioning interaction obtained when each positioning interaction finishes, and area triggering positioning just initiates client for the location target terminal position message only when the target terminal position that positioning interaction obtained meets the location and initiates area triggering condition that client proposed.These differences of cycle triggered location and area triggering positioning can't make the execution mode that portable terminal is carried out trigger positioning method provided by the invention that too big difference is arranged.Therefore, below mainly be positioned at network with trigger still to be positioned at terminal be standard, describe the embodiment of technical scheme provided by the present invention respectively, each embodiment has illustrated the situation of cycle triggered location and area triggering positioning simultaneously.

Please refer to Fig. 1, Fig. 1 is the flow chart that portable terminal is carried out trigger positioning method embodiment one provided by the invention.In the present embodiment, trigger is positioned at H-SLP.

Step 101, the location is initiated client and is proposed running fix agreement triggered location request (MLP TLRR, Mobile Location Protocol Triggered Location ReportingRequest) to H-SLP.

MLP TLRR message comprises the sign that client identification and target terminal are initiated in the location at least.

Require target terminal is carried out the cycle triggered location if locate the initiation client, can also comprise the zero hour of cycle location in this message and/or stop the moment and/or blanking time, wherein termination can replace with the duration constantly.

Require target terminal is carried out area triggering positioning if client is initiated in the location, can also comprise the zero hour and/or the area triggering condition of monitored object terminal location in this message.

Step 102, H-SLP carries out authentication, privacy inspection and route inspection.

The purpose of authentication is, judges that the location initiates the client positioning service of being asked of whether having the right to use.

The purpose of privacy inspection is, judges whether location initiation client has the right to obtain target terminal position to H-SLP request positioning service.

If initiating client, the location haves no right to ask positioning service, then initiate client and return MLP triggered location answer (TLRA to the location, Triggered Location Reporting Answer) message, utilize the result parameter notice location in this message to initiate terminal, this cycle triggered location request has been rejected.Have the right to ask positioning service if client is initiated in the location, then execution in step 103.

The purpose of route inspection is, judge that target terminal is in non-roaming state, and definite terminal is supported the SUPL triggered location.

Step 103, H-SLP uses Short Message Service (SMS, Short Message Service) or WAP (wireless access protocol) (WAP, Wireless Access Protocol) mode sends SUPL location initialization (SUPL INIT) message to target terminal, informs that target terminal has a triggered location request to need target terminal to confirm.

This message comprises localization method, align_type and trigger mode at least, and wherein trigger mode represents that trigger is positioned at H-SLP and still is positioned at target terminal.

Step 104, target terminal will oneself be tied on the data network, sets up to be connected with the IP of H-SLP.

Step 105, if target terminal is agreed this cycle triggered location request, and the localization method, align_type, the trigger mode that indicate in the support SUPL INIT message, then send the SUPL triggered location and begin (SUPL TRIGGERED START) message, comprise terminal capability parameter and terminal result in the message at least the location Notification Validation to H-SLP.Terminal capability comprises: the localization method that target terminal is supported, as auxiliary agps system (A-GPS, the Assisted Global PositioningSystem) localization method of: terminal, based on the A-GPS localization method of terminal etc.; And located in connection agreement, as: Radio Resource location service agreement (RRLP, Radio Resource Location serviceProtocol), Radio Resource control (RRC, Radio Resource Control) agreement, telecommunications industry association (TIA, Telecommunication Industries Association)-801 agreements etc.

If target terminal is disagreed with this cycle triggered location request, then target terminal sends SUPL to H-SLP and finishes (SUPL END) message, and release is connected and related resource with the IP of H-SLP, and execution in step 107 then.

Step 106 is agreed at target terminal under the situation of triggered location request, and H-SLP returns SUPL triggered location response (SUPL TRIGGERED RESPONSE) message to target terminal.

At least comprise the final localization method of determining that is used for location sessions and the sign of unique this triggered location of indication in this message.

If the positioning interaction first time between H-SLP and the target terminal is not to begin very soon to carry out, then H-SLP disconnects the current IP connection and discharges related resource after sending SUPL TRIGGERED RESPONSE; Target terminal also disconnects the current IP connection and discharges related resource after receiving SUPL TRIGGERED RESPONSE.Otherwise if the positioning interaction between H-SLP and the target terminal needs to begin very soon to carry out, H-SLP comprises predefined tag field in this message, is used to indicate target terminal to keep current IP to connect; Simultaneously, H-SLP self also keeps current IP to connect.

In order to judge whether the positioning interaction between H-SLP and the target terminal begins to carry out very soon, can preestablish a time threshold, if pick up counting from the current time, can carry out the positioning interaction between H-SLP and the target terminal in time threshold, the positioning interaction that so just is judged as between H-SLP and the target terminal can begin to carry out very soon.

Step 107, H-SLP returns the MLP triggered location to location initiation client and answers (TLRA, Triggered Location Reporting Answer) message, and the triggered location request that expression is initiated the client proposition by the location has been accepted by target terminal.

If target terminal has been refused the triggered location request in step 105, then comprise the result parameter in the MLP TLRA message, identify the reason of location failure.

Step 108, H-SLP initiates the trigger condition that client proposes according to the location in MLP TLRR message, position when mutual at needs and target terminal, sends SUPL to target terminal and triggers initialization (SUPL TRIGGERED INIT) message.

At least the sign that comprises this triggered location of unique identification described in the step 106 in the SUPL TRIGGERED INIT message.If kept effective I P to be connected between H-SLP and the SET, then H-SLP can directly use this connection to issue SUPL TRIGGERED INIT message to target terminal, otherwise H-SLP sends this message by SMS or WAP to target terminal.

Step 109, target terminal sends SUPL location initialization (SUPL POS IN IT) message with the positioning interaction between beginning and the H-SLP to H-SLP.

Step 110 positions between H-SLP and the target terminal alternately, obtains target terminal position.

Step 111, H-SLP sends the SUPL location to target terminal and finishes (SUPL POS END) message, to finish current positioning interaction.

If the next positioning interaction between H-SLP and the target terminal is not to begin very soon to carry out, then H-SLP disconnects the current IP connection and discharges related resource after sending SUPL POS END message; Target terminal also disconnects the current IP connection and discharges related resource after receiving SUPL POS END message.Otherwise if the next positioning interaction between H-SLP and the target terminal needs to begin very soon to carry out, H-SLP comprises predefined tag field in SUPL POS END message, is used to indicate target terminal to keep current IP; Simultaneously, H-SLP self also keeps current IP to connect.

For the situation of cycle triggered location, H-SLP also initiates client transmission MLP triggered location report (TLREP, Triggered Location Report) message to the location client is initiated in target terminal position notice location.Situation for area triggering positioning, whether the target terminal position that H-SLP at first obtains in the determining step 110 satisfies the location is initiated the area triggering condition that terminal is set in MLP TLRR message, send MLP TLREP message client is initiated in target terminal position notice location if satisfy then initiate client to the location.

Step 112 is initiated the triggered location condition that client proposes according to the location in MLP TLRR message, step 108 is arrived step 111 repeated several times.

Step 113, after execution in step 110 is obtained target terminal position the last time, H-SLP after target terminal sends SUPL END message, disconnect with target terminal between IP be connected; H-SLP can also initiate client transmission MLP TLREP message to the location client is initiated in target terminal position notice location; H-SLP discharges the resource relevant with this triggered location.

Target terminal receive disconnect after the SUPL END message with H-SLP between IP is connected and the release resource relevant with this triggered location.

In step 106 and step 111, H-SLP comes the indicating target terminal to keep current IP to be connected by comprise predefined tag field in SUPL TRIGGEREDRESPONSE message and SUPL POS END message respectively.As first kind of replacement scheme, H-SLP comprises being used to the tag field of indicating target terminal to keep current IP to be connected, but comprise a time parameter, determine whether disconnecting the current IP connection and discharge related resource according to this time parameter with the indicating target terminal.This time parameter can be an absolute time value, also can be the value of a time span.If time parameter is absolute time value, then this parameter can be called disconnection constantly, when target terminal arrives in this absolute time, if do not receive the SUPLTRIGGERED INIT message that is used to initiate new positioning interaction that H-SLP sends, then disconnect the current IP connection and discharge related resource; If time parameter is the value of time span, then this parameter can be called the wait duration, target terminal picks up counting after receiving SUPLTRIGGERED RESPONSE message and SUPL POS END message, if before timing arrives this time span, do not receive the SUPL TRIGGERED INIT message that is used to initiate new positioning interaction that H-SLP sends, then disconnect the current IP connection and discharge related resource.Above-mentioned time parameter also can be used to indicate simultaneously H-SLP self whether to disconnect the current IP connection and discharge related resource.As second kind of replacement scheme, can arrange to wait for duration in advance by H-SLP and target terminal, if H-SLP is in SUPL TRIGGERED RESPONSE message or SUPL POSEND message, comprised the tag field that is used to indicate the connection of target terminal maintenance current IP, then H-SLP treats to keep current IP to be connected before duration arrives at these with target terminal.As the third replacement scheme, can arrange to wait for duration in advance by H-SLP and target terminal, after SUPLTRIGGERED RESPONSE message or SUPL POS END message, H-SLP and target terminal are all given tacit consent at these and are treated to keep current IP to be connected before duration arrives.H-SLP need not judge whether next positioning interaction begins very soon in the third replacement scheme.As the 4th kind of replacement scheme, H-SLP can comprise predefined tag field in SUPL TRIGGERED RESPONSE, with the indicating target terminal from current time, before whole triggered location process finishes, all keep current IP to connect, perhaps the indicating target terminal, all remained on the IP that sets up when positioning interaction begins for the first time and connects before whole triggered location process finishes since the positioning interaction first time; Perhaps H-SLP can comprise first kind of wait duration described in the replacement scheme in SUPL TRIGGERED RESPONSE, with the indicating target terminal after receiving SUPL TRIGGERED RESPONSE message, and follow-up each positioning interaction finish after all according to waiting for whether the duration decision disconnects connection.

Please refer to Fig. 2, Fig. 2 provided by the inventionly carries out the flow chart of trigger positioning method embodiment two to portable terminal, and in the present embodiment, trigger is positioned at target terminal.

In Fig. 1, step 101 can be called the initial phase of triggered location to step 107.Be positioned at the situation of target terminal for trigger, the step of initial phase, it is basic identical that just step 201 is positioned at the step of initial phase under the situation of H-SLP to step 207 and trigger, difference has two places: at first, in the step 206 of present embodiment, when H-SLP sends SUPLTRIGGERED RESPONSE message to target terminal,, also carry the zero hour, the termination moment and the blanking time of cycle triggered location in this message for the cycle triggered location.Wherein stop constantly can replacing with the duration; For area triggering positioning, then also carry the zero hour and the area triggering condition of monitored object terminal location in this message.Secondly, in the step 206 of present embodiment, be target terminal rather than H-SLP because when decision positions mutual, therefore, H-SLP can not keep current IP to connect with the indicating target terminal by comprise predefined tag field in SUPLTRIGGERED RESPONSE message.Other identical steps do not repeat them here.

Step 208, target terminal judge whether to have kept effective I P to be connected with H-SLP, if having then directly send SUPL POS INIT message with the positioning interaction between beginning and the H-SLP to H-SLP; If do not have would at first set up with H-SLP between IP is connected, then to H-SLP send SUPL POSINIT message with begin and H-SLP between positioning interaction.

Step 209 positions between H-SLP and the target terminal alternately, obtains target terminal position, and initiates clients report target terminal position by H-SLP to the location.

For the cycle triggered location, if in the positioning interaction between H-SLP and target terminal, be to calculate the target terminal position by target terminal, target terminal directly sends to H-SLP with self terminal location by SUPL report (SUPL REPORT) message so, and positioning interaction finishes.For area triggering positioning, if in the positioning interaction between H-SLP and target terminal, be to calculate the target terminal position by target terminal, target terminal judges at first whether self-position satisfies the area triggering condition so, if satisfy then self-position is sent to H-SLP by SUPL report (SUPL REPORT) message, positioning interaction finishes.After H-SLP obtains the target terminal position, by MLP TLREP message the target terminal position is sent to the location again and initiate client.

For the cycle triggered location, if in the positioning interaction between H-SLP and target terminal, be to calculate the target terminal position by H-SLP, H-SLP promptly finishes positioning interaction later on obtaining the target terminal position so, and H-SLP directly sends to the location by MLP TLREP message with the target terminal position and initiates client.For area triggering positioning, if in the positioning interaction between H-SLP and target terminal, be to calculate the target terminal position by H-SLP, H-SLP at first sends to target terminal with the target terminal position by SUPL position message (SUPL POS REPORT) message so, target terminal judges whether self-position satisfies the area triggering condition, if satisfy then self-position is sent to H-SLP by SUPL report (SUPL REPORT) message, positioning interaction finishes; After H-SLP obtains the target terminal position, by MLP TLREP message the target terminal position is sent to the location again and initiate client.For area triggering positioning and calculate the situation of target terminal position by H-SLP, as a kind of replacement scheme, also can directly whether satisfy the area triggering condition, initiate client if satisfy then the target terminal position is sent to the location by MLP TLREP message by H-SLP according to area triggering condition judgment target terminal position.

If the next positioning interaction between H-SLP and the target terminal is not to begin very soon to carry out, then H-SLP and target terminal all disconnect current IP and are connected and discharge related resource after this positioning interaction finishes.Otherwise, if the next positioning interaction between H-SLP and the target terminal needs to begin very soon to carry out, target terminal can be in SUPL POS INIT message, in any a piece of news before perhaps positioning interaction finishes after SUPL POS INIT message, comprise predefined tag field and keep current IP to connect with indication H-SLP; Simultaneously, target terminal self also keeps current IP to connect.

Step 210, the triggered location condition according to H-SLP proposes in SUPL TRIGGERED RESPONSE message arrives step 209 repeated several times with step 208.

Step 211, the last time after the execution in step 209, H-SLP after target terminal sends SUPLEND message, disconnect with target terminal between IP is connected and the release resource relevant with this triggered location; Target terminal receive disconnect after the SUPL END message with H-SLP between IP is connected and the release resource relevant with this triggered location.

H-SLP can also initiate client transmission MLP TLREP message to the location client is initiated in target terminal position notice location.

In step 208 and/or step 209, target terminal by with the interaction message of H-SLP in comprise predefined tag field and indicate H-SLP to keep current IP to be connected.As first kind of replacement scheme, target terminal can with the interaction message of H-SLP in comprise a time parameter, determine whether disconnecting current IP with indication H-SLP according to this time parameter and connect and discharge related resource.This time parameter can be an absolute time value, also can be the value of a time span.If time parameter is absolute time value, then this parameter can be called and disconnect constantly, when H-SLP arrives in this absolute time,, then disconnect the current IP connection and discharge related resource if do not receive the SUPL POSINIT message that is used to initiate new positioning interaction that target terminal is sent; If time parameter is the value of time span, then this parameter can be called the wait duration, H-SLP picks up counting after the positioning interaction with target terminal finishes, if before timing arrives this time span, do not receive the SUPL POS INIT message that is used to initiate new positioning interaction that H-SLP sends, then disconnect the current IP connection and discharge related resource.Above-mentioned time parameter also can be used to indicate simultaneously target terminal self whether to disconnect the current IP connection and discharge related resource.As second kind of replacement scheme, can arrange to wait for duration in advance by H-SLP and target terminal, if target terminal is in SUPL POS INIT message, in any a piece of news before perhaps positioning interaction finishes after SUPLPOS INIT message, comprised and be used to indicate H-SLP to keep current IP to connect predefined tag field, then H-SLP treats to keep current IP to be connected before duration arrives at these with target terminal.As the third replacement scheme, can arrange to wait for duration in advance by H-SLP and target terminal, finish the back or after positioning interaction finishes at initial phase, H-SLP gives tacit consent at these with target terminal and treats to keep current IP to be connected before duration arrives.Target terminal need not judge whether next positioning interaction begins very soon in the third replacement scheme.

The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
