The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Fig. 1 is the system block diagram of realization SUPL provided by the invention, and as shown in Figure 1, it mainly comprises:
SET is used for to H-SLP transmit status notice, to report the state information of self;
During the SET start, giving H-SLP transmit status parameter is the state notifying of reaching the standard grade; During shutdown, giving H-SLP transmit status parameter is the state notifying of off-line.
Further, SET is used to receive the state notifying response that H-SLP returns.
SP: be used for sending Location Request: SLIR or TLRR, and be used to receive the positioning result that H-SLP returns to H-SLP;
H-SLP: the state notifying that is used to receive SET, and be used to set up and preserve the state recording of SET: the state information that comprises SET sign and SET, and in the Location Request of receiving SP and judge that the corresponding SET of SET sign that this request message carries is current during for off-line state, send the location notice to SET, and after receiving the location push-notification-answer that SET returns, begin SET is positioned, be used for sending the positioning result of SET to SP.
Further, H-SLP is used for giving SET return state push-notification-answer after the state parameter of receiving the SET transmission is the state notifying of reaching the standard grade.
Prerequisite of the present invention is: SET provides the state information of self in real time to H-SLP.Concrete mode can be:
One, when start, sends the state notifying of reaching the standard grade to H-SLP; When shutdown, send the off-line state notice to H-SLP.
Particularly, state notifying can comprise SET sign, state parameter: reach the standard grade or off-line, the current place of SET subdistrict position sign, it is the state notifying of reaching the standard grade that the state notifying of reaching the standard grade here refers to state parameter, and the off-line state notice refers to the state notifying that state parameter is an off-line.
State notifying can carry by IP, also can carry by short message service (SMS).
After H-SLP receives the state notifying of reaching the standard grade, can be to SET return state push-notification-answer, otherwise SET thinks that H-SLP confiscates this notice, thus repeat to send this notice.
Two, SET is in start or when shutdown, can provide option to H-SLP " transmissions " and " not sending " current state to the user, if the user selectes " transmission ", just will reach the standard grade state notifying or off-line state of SET notified and sent to H-SLP.
Three, SET self is provided with the option that sends current state to H-SLP, if selected this option of user, SET just sends reach the standard grade state notifying or off-line state notice from trend H-SLP when start or shutdown so; If the user cancels selected this option, SET just no longer sends reach the standard grade state notifying or off-line state notice to H-SLP.
Fig. 2 is the flow chart of realization SUPL provided by the invention, and as shown in Figure 2, its concrete steps are as follows:
Step 201:SP is sent to H-SLP with Location Request, and this request message carries the sign of SET.
Step 202: according to the state information that SET reports, H-SLP judge the SET of this Location Request appointment current whether be off-line state, if, execution in step 203; Otherwise, execution in step 204.
Step 203:H-SLP does not send the location notice to this SET, and returns the location failure information of this SET to SP, and this flow process finishes.
Step 204:H-SLP sends the location notice to this SET.
In the SUPL agreement, this location notice sends by SUPL initialization (INIT) message.
Step 205:H-SLP receives the location push-notification-answer that SET returns, and begins the location, and the location finishes, and obtains the position of SET.
In the SUPL agreement, this location push-notification-answer returns by SUPL location initialization (POS INIT) message.
Step 206:H-SLP returns the positional information of this SET to SP.
Fig. 3 is that the present invention realizes the flow chart of locating immediately, and as shown in Figure 3, its concrete steps are as follows:
The H-SLP of step 301:SET ownership preserves in real time and upgrades all state informations at the SET of self signatory location service.
When SET start or shutdown, send reach the standard grade state notifying or off-line state notice, after H-SLP receives, according to upgrade in time the state information of the SET that self preserves of this notice to H-SLP.
Step 302:SP is sent to H-SLP by the LCS agency who operates in self with SLIR message, and this message is carried the sign of SET.
If H-SLP under the SET and the request SLP (R-SLP) under the SP are not same SLP, then give H-SLP with the SLIR forwards by R-SLP.
The state information of the SET that step 303:H-SLP preserves according to self, judge the SET of this SLIR appointment current whether be off-line state, if, execution in step 304; Otherwise, execution in step 305.
Step 304:H-SLP does not send the location notice to this SET, and fail in the location of this SET of sign in SLIA or SLIREP message, and execution in step 308 then.
Step 305:H-SLP sends the location notice to this SET.
Step 306:SET gives H-SLP restoring to normal position push-notification-answer after receiving this location notice.
Step 307:H-SLP receives this response, begins SET is positioned, and the location finishes, and obtains the position of SET.
Step 308:H-SLP acts on behalf of to SP by LCS and returns SLIA or SLIREP.
Carried the position of locating successful SET in the message, the SET that locatees failure has also been done the location failure identified.
If H-SLP under the SET and the R-SLP under the SP are not same SLP, then H-SLP can give SP with SLIA or SLIREP forwards by R-SLP.
Fig. 4 is the flow chart of location performance period of the present invention, and as shown in Figure 4, its concrete steps are as follows:
Step 401:SP is sent to H-SLP by the LCS agency who operates in self with TLRR message, and this message is carried the sign of SET.
Also the cycle of carrying is located the initial moment, cycle location finish time, positioning time interval, alignment quality (QoP) etc. to this message simultaneously.
If H-SLP under the SET and the R-SLP under the SP are not same SLP, then give H-SLP with the TLRR forwards by R-SLP.
Step 402:H-SLP obtains the state information of all SET of this TLRR appointment.
The state information that H-SLP obtains all SET of TLRR appointment can realize in the following manner:
One, H-SLP is based upon the state recording of all SET of the location service of self contracting, this state recording comprises: the state information of SET sign and this SET, as long as H-SLP receives the state notifying that SET sends, just preserve and upgrade the state information of this SET in real time according to this notice, after receiving the TLRR that SP sends, H-SLP searches the current state of the SET of this TLRR appointment in this state recording;
Two, only after receiving the TLRR of SP, H-SLP just begins to set up the state recording of all SET of this TLRR appointment: the state information of SET sign and this SET, and the state notifying that sends according to SET, preserve and upgrade the state information of SET in real time, according to this state recording, determine the current state of the SET of TLRR appointment simultaneously.
The state of SET has three kinds: sky, online or off-line.
Step 403:H-SLP judge the SET of TLRR appointment current whether be off-line state, if, execution in step 404; Otherwise, execution in step 405.
Step 404:H-SLP does not send the location notice to this SET, and fail in the location of this SET of sign in TLRA or TLR message, and execution in step 408 then.
Step 405:H-SLP sends the location notice to SET.
Step 406:SET gives H-SLP restoring to normal position push-notification-answer after receiving this location notice.
Step 407:H-SLP receives this response, begins this SET is positioned, and the location finishes, and obtains the position of SET.
Step 408:H-SLP acts on behalf of to SP return period location response (TLRA, Triggered Location Reporting Answer) or cycle positioning reporting (TLR, TriggeredLocation Report) by LCS.
Carried the position of locating successful SET in the message, the SET that locatees failure has also been done the location failure identified.
If H-SLP under the SET and the R-SLP under the SP are not same SLP, then H-SLP can give SP with TLRA or TLR forwards by R-SLP.
Step 409:H-SLP judges that current time is whether more than or equal to location finish time in cycle, if this flow process finishes; If not and next time location arrive the zero hour, then return step 402.
After H-SLP receives TLRR message, an orientation triggering timer is set, this timer starts in the cycle location of TLRR message appointment the zero hour, then according to positioning time of TLRR message appointment at interval, in the location of TLRR message appointment before the finish time, send one to H-SLP at interval every a positioning time and trigger message, H-SLP begins new position fixing process with indication.That is to say that the location of adjacent twice position fixing process differs a positioning time at interval the zero hour.
In the cycle position fixing process, if when this locatees beginning, the state of certain SET is an off-line, and when next time, the location began, H-SLP did not receive the state notifying of reaching the standard grade of this SET yet, and in this position fixing process, H-SLP still can not give this SET transmission location notice so; Reported the state notifying of reaching the standard grade up to this SET to H-SLP, H-SLP with the state of this SET be changed to online after, H-SLP just can send the location notice to this SET in next position fixing process.
If the state recording of SET is set up after receiving TLRR message, so, after the cycle location arrival finish time, H-SLP can remove this state recording.
The above only is process of the present invention and method embodiment, in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is not equal to replacement, improvement etc., all should be included within protection scope of the present invention.
