Description

区域触发定位方法及装置 Area trigger positioning method and device

技术领域 technical field

本发明涉及基于用户平面的移动位置业务技术领域,具体涉及一种区域触发定位方法及装置。The present invention relates to the technical field of mobile location services based on user plane, in particular to an area trigger positioning method and device.

背景技术 Background technique

SUPL(安全用户平面定位)是一种采用用户平面的标准协议、允许移动电话用户与定位服务器交互而获得移动定位终端的位置的通讯协议。SUPL (Secure User Plane Positioning) is a communication protocol that adopts the standard protocol of the user plane and allows the mobile phone user to interact with the positioning server to obtain the position of the mobile positioning terminal.

一般的即时终端定位分为网络始发定位和终端始发定位:一个请求定位的发起方通过其客户端发起对另外一个终端的定位属于网络始发定位;发起对自己的定位属于终端始发定位。其过程分别为:General real-time terminal positioning is divided into network-initiated positioning and terminal-initiated positioning: an initiator requesting positioning initiates positioning of another terminal through its client, which belongs to network-initiated positioning; initiating its own positioning belongs to terminal-initiated positioning . The processes are as follows:

当一个请求定位的发起方的客户端通过驻留在其MLS(移动定位服务)应用发起对另外一个终端的定位时,目标终端的H-SLP(归属定位服务器)通知目标终端开始定位,通过目标终端和该H-SLP的会话,完成对目标终端的位置计算,最后将计算结果通知MLS客户端,完成定位过程;与此相应,当SUPL终端发起对自己的定位时,该终端与其归属的H-SLP会话,并最终即时获得自己的位置。When an initiator client requesting positioning initiates the positioning of another terminal through its MLS (Mobile Location Service) application, the H-SLP (Home Location Server) of the target terminal notifies the target terminal to start positioning. The session between the terminal and the H-SLP completes the location calculation of the target terminal, and finally notifies the MLS client of the calculation result to complete the positioning process; correspondingly, when the SUPL terminal initiates its own positioning, the terminal and its H-SLP -SLP sessions and end up with instant access to your location.

而触发定位过程不同于上述即时定位过程。当客户端的MLS应用发起对目标终端的一个触发定位时,触发定位条件驻留在目标终端的H-SLP或目标终端中,当满足触发条件时,触发该次的定位会话。如果触发器驻留在H-SLP上时则触发网络始发的定位过程,如果触发器驻留在目标终端上则触发终端始发的定位过程。However, the triggered positioning process is different from the above-mentioned instant positioning process. When the client's MLS application initiates a trigger location for the target terminal, the trigger location condition resides in the target terminal's H-SLP or the target terminal, and when the trigger condition is met, the location session is triggered. If the trigger resides on the H-SLP, the network-initiated positioning process is triggered, and if the trigger resides on the target terminal, the terminal-initiated positioning process is triggered.

周期性定位是触发定位的一种,它是在一段时间内以一定的时间间隔触发对目标终端的定位,目的是了解目标终端在一段时间内的位置信息。Periodic positioning is a kind of triggered positioning, which triggers the positioning of the target terminal at a certain time interval within a certain period of time, and the purpose is to know the position information of the target terminal within a certain period of time.

基于区域的触发定位是网络或终端周期性地检测目标终端是否处于、进入或离开特定的区域,如果是则满足触发条件,触发位置报告。The area-based trigger positioning is that the network or the terminal periodically detects whether the target terminal is in, enters or leaves a specific area, and if so, the trigger condition is met and the location report is triggered.

网络始发的触发定位流程如图1所示:其中,步骤h、j、l只在满足区域触发条件时才执行,执行这些步骤后会跳转到最后一步m,结束整个定位过程。The network-initiated trigger location process is shown in Figure 1. Among them, steps h, j, and l are only executed when the trigger conditions of the area are met. After executing these steps, it will jump to the last step m to end the entire location process.

终端始发的触发定位流程如图2所示:其中,步骤d、f、h只在满足区域触发条件时才执行,执行这些步骤后会跳转到最后一步i,结束整个定位过程。The trigger location process initiated by the terminal is shown in Figure 2: among them, steps d, f, and h are only executed when the trigger conditions of the area are met. After these steps are executed, it will jump to the last step i to end the entire location process.

不论是网络发起的还是终端发起的区域触发定位,每个完整的定位流程分为初始阶段和定位会话阶段。触发器在网络侧和终端侧只是定位会话的流程有所不同。Regardless of whether it is network-initiated or terminal-initiated area-triggered positioning, each complete positioning process is divided into an initial phase and a positioning session phase. The only difference between the trigger on the network side and the terminal side is the process of locating the session.

触发器位于网络的区域触发定位过程为:定位服务器在收到SUPL代理或目标终端发起的区域触发定位请求后,将区域触发条件保存在本地,并根据定位服务器上的触发开始时间开始周期性定位。定位服务器周期性地向目标终端发起多次立即定位流程,每次在获取到目标终端的精确位置后与触发定位任务中指定的目标区域以及区域触发类型(进入、离开、在内部)相比较,如果满足触发条件,则向定位发起方上报区域触发定位报告。The trigger location process of the area where the trigger is located in the network is as follows: After receiving the area trigger positioning request initiated by the SUPL agent or the target terminal, the positioning server saves the area trigger condition locally, and starts periodic positioning according to the trigger start time on the positioning server . The positioning server periodically initiates multiple immediate positioning processes to the target terminal, each time after obtaining the precise position of the target terminal, it compares it with the target area specified in the trigger positioning task and the area trigger type (entering, leaving, inside), If the trigger condition is met, report the area trigger location report to the location initiator.

如图3所示,为触发器在网络侧的定位会话流程:As shown in Figure 3, it is the location session process of the trigger on the network side:

当到达每次的定位时刻时,定位服务器发起和终端的定位会话,有以下两种情况:When the positioning time is reached each time, the positioning server initiates a positioning session with the terminal, there are the following two situations:

1.网络发起的定位请求:当采用基于终端的定位计算方法时,如果辅助数据不需要更新,则定位会话中目标终端计算完成后向定位服务器发送SUPLREPORT消息,通知本次定位结果,前面的几步是可选的;当采用基于终端辅助的定位计算方法时,定位服务器计算定位结果,由定位服务器判断是否满足区域触发条件,如果满足通知SUPL代理SUPL Agent。1. Positioning request initiated by the network: When using the terminal-based positioning calculation method, if the auxiliary data does not need to be updated, the target terminal in the positioning session will send a SUPLREPORT message to the positioning server after the calculation is completed to notify the positioning result. This step is optional; when using the terminal-assisted positioning calculation method, the positioning server calculates the positioning result, and the positioning server judges whether the area trigger condition is satisfied, and if it is satisfied, the SUPL Agent is notified.

2.终端发起的定位请求:当采用基于终端的定位计算方法时,如果辅助数据不需要更新,则定位会话中目标终端计算完成后向定位服务器发送SUPLREPORT消息,通知本次定位结果,前面的几步是可选的;当采用基于终端辅助的定位计算方法时,由定位服务器计算定位结果并判断是否满足区域触发条件,如果满足通知SUPL代理SUPL Agent。2. Positioning request initiated by the terminal: When the terminal-based positioning calculation method is adopted, if the auxiliary data does not need to be updated, the target terminal in the positioning session will send a SUPLREPORT message to the positioning server after the calculation is completed to notify the positioning result of this time. The first step is optional; when using the positioning calculation method based on terminal assistance, the positioning server calculates the positioning result and judges whether the area trigger condition is satisfied, and if it is satisfied, the SUPL Agent is notified.

触发器位于终端的区域触发定位过程为:目标终端在收到SUPL代理发起的区域触发定位请求后,将区域触发条件保存在本地,如果是网络始发的定位,则会将触发定位任务通知目标终端。目标终端根据触发器设定的条件周期地向定位服务器发起定位请求,通过与定位服务器的交互获取到精确位置结果后,和本地保存的目标区域以及触发类型(进入、离开、在内部)相比较,如果满足触发条件,则目标终端通过定位服务器向SUPL代理上报区域触发定位报告或者向内部的位置应用上报区域触发定位报告。The process of triggering location where the trigger is located in the terminal is as follows: After the target terminal receives the location triggering request initiated by the SUPL agent, it saves the location triggering condition locally. If the location is initiated by the network, it will notify the target of the location triggering task. terminal. The target terminal periodically initiates a positioning request to the positioning server according to the conditions set by the trigger. After obtaining the precise position result through interaction with the positioning server, it compares it with the locally saved target area and trigger type (entry, exit, internal) , if the trigger condition is met, the target terminal reports the area-triggered positioning report to the SUPL agent through the positioning server or reports the area-triggered positioning report to the internal location application.

如图4所示,为触发器在终端侧的定位会话流程:As shown in Figure 4, it is the location session process of the trigger on the terminal side:

当到达每次的定位时刻时,终端发起和服务器的定位会话,分为以下两种情况:When the positioning time is reached each time, the terminal initiates a positioning session with the server, which can be divided into the following two situations:

1.网络发起的定位请求:当采用基于终端的定位计算方法时,如果辅助数据不需要更新,则定位会话中目标终端计算完成后向定位服务器发送SUPLREPORT消息,通知本次定位结束,前面的几步是可选的;当采用基于终端辅助的定位计算方法时,服务器计算定位结果,计算后通过SUPL REPORT消息向目标终端报告定位结果,目标终端判断是否满足区域触发条件,如果满足则通过SUPL REPORT消息通知定位服务器区域事件触发。1. Positioning request initiated by the network: When using the terminal-based positioning calculation method, if the auxiliary data does not need to be updated, the target terminal in the positioning session will send a SUPLREPORT message to the positioning server after the calculation is completed, notifying the end of this positioning. The first step is optional; when using the positioning calculation method based on terminal assistance, the server calculates the positioning result, and reports the positioning result to the target terminal through the SUPL REPORT message after calculation. Message notification location server area event trigger.

2.终端发起的定位请求:当采用基于终端的定位计算方法时,如果辅助数据不需要更新,则定位会话中目标终端计算完成后向定位服务器发送SUPLREPORT消息,通知本次定位结束,前面的几步是可选的;当采用基于终端辅助的定位计算方法时,服务器计算定位结果,计算后通过SUPL REPORT消息向目标终端报告定位结果,目标终端判断是否满足区域触发条件,如果满足通知内部应用。2. Positioning request initiated by the terminal: When using the terminal-based positioning calculation method, if the auxiliary data does not need to be updated, the target terminal in the positioning session will send a SUPLREPORT message to the positioning server after the calculation is completed, notifying the end of this positioning. This step is optional; when the terminal-based positioning calculation method is adopted, the server calculates the positioning result, and reports the positioning result to the target terminal through the SUPL REPORT message after the calculation. The target terminal judges whether the area trigger condition is satisfied, and if so, notifies the internal application.

在上述各流程中,对于区域触发定位,其定位周期的开始时间和结束时间可能都是发起者确定好的,定位的周期间隔通常是由定位服务器或终端通过计算或协商在区域触发的初始阶段确定。周期一经确定就不再更改,直到定位结束或者检测到满足指定的区域条件。但是如果目标终端在较长时间内在较小地理范围内活动,或者目标终端非常缓慢地或快速地向目标区域逼近时,此时目标终端在一个定位周期间隔内移动的距离很长或很短,采用固定的定位周期并不能有效地监控目标终端的精确位置。可见,现有对该目标终端的周期定位则不够智能化,从定位开始到结束始终以相同的定位周期间隔触发对目标终端的定位,还会造成网络和终端资源的较大浪费。In the above processes, for area-triggered positioning, the start time and end time of the positioning cycle may be determined by the initiator, and the positioning cycle interval is usually calculated or negotiated by the positioning server or terminal in the initial stage of area triggering Sure. Once the period is determined, it will not change until the positioning is completed or the specified area conditions are detected. However, if the target terminal is active in a small geographical range for a long time, or the target terminal is approaching the target area very slowly or quickly, and the distance that the target terminal moves within a positioning cycle interval is very long or very short, Using a fixed positioning period cannot effectively monitor the precise position of the target terminal. It can be seen that the existing periodic positioning of the target terminal is not intelligent enough, and the positioning of the target terminal is always triggered at the same positioning cycle interval from the beginning to the end of the positioning, which will also cause a large waste of network and terminal resources.

具体实施方式 Detailed ways

本发明的核心在于采用周期可变的区域触发定位,在区域触发定位的初始阶段,定位服务器或目标终端确定定位周期参数;在区域触发定位过程中,定位服务器或目标终端在周期性定位过程中根据目标终端的移动速度调整周期性定位的周期间隔;经过调整后的定位周期间隔后,开始下次区域触发定位过程。具体地,在区域触发定位的初始阶段,可以根据目标终端当前位置与目标区域间的距离确定定位周期间隔;在区域触发定位过程中,当目标终端缓慢地背离目标区域移动时,适当地增加定位周期间隔;反之,当目标终端快速地朝向目标区域移动时,适当地缩小定位周期间隔The core of the present invention is to adopt area-triggered positioning with a variable period. In the initial stage of area-triggered positioning, the positioning server or target terminal determines the positioning period parameters; during the process of area-triggered positioning, the positioning server or target terminal The periodic interval of periodic positioning is adjusted according to the moving speed of the target terminal; after the adjusted positioning periodic interval, the next area trigger positioning process is started. Specifically, in the initial stage of area-triggered positioning, the positioning cycle interval can be determined according to the distance between the current position of the target terminal and the target area; during the process of area-triggered positioning, when the target terminal slowly moves away from the target area, the positioning cycle interval; on the contrary, when the target terminal moves quickly towards the target area, the positioning cycle interval is appropriately reduced

为了使本技术领域的人员更好地理解本发明方案,下面结合附图和实施方式对本发明作进一步的详细说明。In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

参照图5,图5示出了本发明方法的实现流程,包括以下步骤:With reference to Fig. 5, Fig. 5 has shown the implementation process of the method of the present invention, comprises the following steps:

步骤501:在区域触发定位的初始阶段,确定定位周期间隔。Step 501: In the initial stage of area-triggered positioning, determine the positioning cycle interval.

本技术领域人员知道,不论是网络发起的还是终端发起的区域触发定位过程,当目标终端的归属定位服务器收至定位请求方的定位请求时,需要在初始阶段协商定位方法等参数。Those skilled in the art know that whether the area-triggered positioning process is initiated by the network or the terminal, when the home positioning server of the target terminal receives the positioning request from the positioning requester, it needs to negotiate parameters such as the positioning method in the initial stage.

在本发明中,根据需要,可以初始阶段由定位服务器和目标终端协商确定第一次定位的起始时间及定位周期间隔等参数;也可以由请求方确定或者由定位服务器根据定位请求方提出的触发条件来确定。为了获得更优化合理的每一次定位的起始时间,可以由定位服务器或目标终端根据目标终端当前位置与目标区域间的距离确定定位周期间隔。In the present invention, as required, parameters such as the starting time of the first positioning and the positioning cycle interval can be determined through negotiation between the positioning server and the target terminal at the initial stage; Trigger conditions are determined. In order to obtain a more optimal and reasonable start time for each positioning, the positioning server or the target terminal may determine the positioning cycle interval according to the distance between the current position of the target terminal and the target area.

步骤502:在周期性定位过程中,根据目标终端的移动速度调整本次定位至下次定位的定位周期间隔。Step 502: During the periodical positioning process, adjust the positioning cycle interval from this positioning to the next positioning according to the moving speed of the target terminal.

当开始周期性定位时,完成第一次定位过程。在前面现有技术中已经提到,区域触发定位可以由网络发起,也可以由终端发起,触发器可以在网络侧,也可以在终端侧,在本发明中同样适用。When periodic positioning is started, the first positioning process is completed. It has been mentioned in the prior art that area trigger positioning can be initiated by the network or by the terminal, and the trigger can be on the network side or on the terminal side, which is also applicable in the present invention.

参照图3所示触发器在网络侧的定位会话流程,定位服务器向目标终端发送SUPL TRIGGERED INIT(安全用户面触发起始)消息,开始定位会话,目标终端向定位服务器回应SUPL POS INIT(安全用户面定位起始)消息。当采用基于终端辅助的定位计算方法时,在该消息中包含目标终端当前所在的小区信息(包括移动国家码、移动网络码、位置区域码、小区标识等信息),由定位服务器根据这些信息计算目标终端当前的位置,并判断是否满足区域触发条件,如果满足通知SUPL代理;当采用基于终端的定位计算方法时,则目标终端计算其位置后向定位服务器发送SUPL REPORT(安全用户面报告)消息,通知本次定位结果。With reference to the positioning session process of the trigger on the network side shown in Figure 3, the positioning server sends a SUPL TRIGGERED INIT (secure user plane trigger initiation) message to the target terminal to start the positioning session, and the target terminal responds to the positioning server with a SUPL POS INIT (secure user plane trigger initiation) message. face positioning start) message. When the positioning calculation method based on terminal assistance is adopted, the information of the cell where the target terminal is currently located (including mobile country code, mobile network code, location area code, cell identity, etc.) The current position of the target terminal, and judge whether the trigger condition of the area is met, and if it is satisfied, notify the SUPL agent; when the terminal-based positioning calculation method is adopted, the target terminal calculates its position and sends a SUPL REPORT (secure user plane report) message to the positioning server , to notify the result of this positioning.

再参照图4所示触发器在终端侧的定位会话流程,目标终端向定位服务器发送SUPL POS INIT消息,开始定位会话,当采用基于终端辅助的定位计算方法时,由定位服务器根据这些信息计算目标终端当前的位置,计算后通过SUPL REPORT消息向目标终端报告定位结果,目标终端判断是否满足区域触发条件,如果满足通知内部应用;当采用基于终端的定位计算方法时,如果辅助数据不需要更新,则目标终端计算其位置后向定位服务器发送SUPLREPORT消息,通知本次定位结果。如果需要更新辅助数据,则利用SUPLREPORT步骤前的消息即可完成定位计算及通知过程。Referring again to the positioning session process of the trigger on the terminal side shown in Figure 4, the target terminal sends a SUPL POS INIT message to the positioning server to start the positioning session. The current position of the terminal, after calculation, reports the positioning result to the target terminal through the SUPL REPORT message, and the target terminal judges whether the area trigger condition is satisfied, and if so, notifies the internal application; when using the terminal-based positioning calculation method, if the auxiliary data does not need to be updated, After calculating its position, the target terminal sends a SUPLREPORT message to the positioning server to notify the positioning result. If it is necessary to update the auxiliary data, the positioning calculation and notification process can be completed by using the message before the SUPLREPORT step.

本发明中每次的定位会话过程与上述相同,只是在第一次定位完成后,需要记录目标终端的位置参数,在经过初始阶段商定的定位周期间隔到达第二次周期定位时间后,估计目标终端的移动速度,然后根据该移动速度计算目标终端在一个定位周期间隔内所移动的距离L。根据该距离L及移动方向是朝向目标区域还是背离目标区域来决定缩小或是增加下一个定位周期间隔。Each positioning session process in the present invention is the same as above, only after the first positioning is completed, the position parameters of the target terminal need to be recorded, and after the positioning cycle interval agreed in the initial stage reaches the second cycle positioning time, the target terminal is estimated The moving speed of the terminal, and then calculate the distance L moved by the target terminal within one positioning cycle interval according to the moving speed. According to the distance L and whether the moving direction is towards the target area or away from the target area, it is decided to reduce or increase the next positioning cycle interval.

当服务器或目标终端获得第二次的位置结果后,如果结果中包含有速度参数,可以使用该速度参数,计算得到目标终端在一个定位周期间隔内所移动的距离L;如果没有速度参数,则可以通过以下方式估计目标终端的移动速度:After the server or the target terminal obtains the second location result, if the result contains a speed parameter, the speed parameter can be used to calculate the distance L that the target terminal moves within a positioning cycle interval; if there is no speed parameter, then The moving speed of the target terminal can be estimated by:

(1)根据在预定时间内目标终端与一固定目标的相对移动距离计算目标终端的移动速度。可以在一次定位周期间隔内设定一个时间段,分别记录在该时间段内目标终端与该已知固定目标的距离,根据该距离及设定的时间段即可得到在该时间段内目标终端的移动速度,将该速度作为目标终端在该定位周期间隔内移动速度的估计值。特别地,可以分别记录在前一次定位及本次定位时目标终端与该已知固定目标的距离,根据这两个距离值可以直接获得目标终端在一个定位周期间隔内所移动的距离L。(1) Calculate the moving speed of the target terminal according to the relative moving distance between the target terminal and a fixed target within a predetermined time. A time period can be set within a positioning cycle interval, and the distance between the target terminal and the known fixed target within this time period can be recorded respectively. According to the distance and the set time period, the target terminal within this time period can be obtained. The moving speed of is used as the estimated value of the moving speed of the target terminal within the positioning cycle interval. In particular, the distances between the target terminal and the known fixed target during the previous positioning and current positioning can be recorded respectively, and the distance L moved by the target terminal within a positioning cycle interval can be directly obtained according to these two distance values.

(2)根据前两次定位过程中获得的目标终端的位置估计目标终端的移动速度。同样,也可以根据这两次的定位结果直接获得目标终端在一个定位周期间隔内所移动的距离L。(2) Estimate the moving speed of the target terminal according to the position of the target terminal obtained in the previous two positioning processes. Similarly, the distance L moved by the target terminal within one positioning cycle interval can also be directly obtained according to the two positioning results.

(3)根据在预定时间内目标终端与目标区域的相对移动距离计算目标终端的移动速度。可以在一次定位周期间隔内设定一个时间段,分别记录在该时间段内目标终端与目标区域的距离,根据该距离及设定的时间段即可得到在该时间段内目标终端的移动速度,将该速度作为目标终端在该定位周期间隔内移动速度的估计值。特别地,可以分别记录在前一次定位及本次定位时目标终端与目标区域的距离,根据这两个距离值可以直接获得目标终端在一个定位周期间隔内所移动的距离L。(3) Calculate the moving speed of the target terminal according to the relative moving distance between the target terminal and the target area within a predetermined time. A time period can be set within a positioning cycle interval, and the distance between the target terminal and the target area within this time period can be recorded respectively, and the moving speed of the target terminal within this time period can be obtained according to the distance and the set time period , taking the velocity as an estimated value of the moving velocity of the target terminal within the positioning cycle interval. In particular, the distances between the target terminal and the target area during the previous positioning and this positioning can be recorded respectively, and the distance L moved by the target terminal within a positioning cycle interval can be directly obtained according to these two distance values.

如果以目标区域为参照点,则根据目标终端与目标区域的相对距离的变化即可得知目标终端的移动方向是背离目标区域还是朝向目标区域;如果以已知的固定目标为参照点,则还需要知道该固定目标与目标区域的相对位置关系,根据该关系及目标终端与该固定目标的相对距离的变化来确定目标终端的移动方向是背离目标区域还是朝向目标区域。If the target area is used as a reference point, then according to the change of the relative distance between the target terminal and the target area, it can be known whether the moving direction of the target terminal is away from the target area or towards the target area; if a known fixed target is used as a reference point, then It is also necessary to know the relative positional relationship between the fixed target and the target area, and determine whether the moving direction of the target terminal is away from the target area or towards the target area according to the relationship and the change of the relative distance between the target terminal and the fixed target.

在确定目标终端的移动方向时,可按以下方式来确定:When determining the moving direction of the target terminal, it can be determined in the following manner:

比如,以GPS(全球定位系统)的定位技术中的地球坐标系(WGS-84地心坐标系)为参考系的测量结果,然后将其转换为本地的高斯平面直角坐标系内的位置。两次周期测量位置间的连线即可在坐标系内得出其相对与坐标轴的方向;另外,还可以采用上次位置和目标区域的连线与本次位置和上次位置连线的夹角确定相对移动方向。如果目标终端的当前位置与上次位置连线的方向与上次位置与目标中心区域点连线的夹角大于90度,则表明目标终端背离目标区域移动;反之,如果目标终端的当前位置与上次位置连线的方向与上次位置与目标中心区域点连线的夹角小于90度,则表明目标终端朝向目标区域移动。For example, take the measurement results of the earth coordinate system (WGS-84 geocentric coordinate system) in GPS (Global Positioning System) positioning technology as the reference system, and then convert it into a position in the local Gaussian plane Cartesian coordinate system. The connection line between the two periodic measurement positions can be used to obtain its relative direction to the coordinate axis in the coordinate system; in addition, the connection line between the last position and the target area and the connection line between the current position and the last position can also be used. The included angle determines the relative movement direction. If the angle between the direction of the line connecting the current position of the target terminal and the previous position and the line connecting the last position and the point in the target central area is greater than 90 degrees, it indicates that the target terminal is moving away from the target area; otherwise, if the current position of the target terminal is in line with If the angle between the direction of the line connecting the last position and the line connecting the last position and the point in the target central area is less than 90 degrees, it indicates that the target terminal is moving towards the target area.

然后,根据目标终端的移动距离L和移动方向来确定本次定位至下次定位的定位周期间隔的调整策略。具体可以采用以下两种调整策略:Then, according to the moving distance L and moving direction of the target terminal, an adjustment strategy for the positioning cycle interval from this positioning to the next positioning is determined. Specifically, the following two adjustment strategies can be adopted:

(1)根据距离L和定位请求方所要求的定位服务质量中的精度的比较结果及目标终端的移动方向确定本次定位至下次定位的定位周期间隔:(1) Determine the positioning cycle interval from this positioning to the next positioning according to the comparison result of the distance L and the accuracy of the positioning service quality required by the positioning requester and the moving direction of the target terminal:

如果目标终端的移动方向背离目标区域,则增加定位周期间隔;If the moving direction of the target terminal deviates from the target area, increase the positioning cycle interval;

如果目标终端的移动方向朝向目标区域,并且距离L大于定位发起方所要求的定位服务质量中的精度要求,则表明在该段时间内目标终端快速逼近目标区域,此时可以缩小定位周期间隔,增加定位频度。If the moving direction of the target terminal is towards the target area, and the distance L is greater than the accuracy requirement in the positioning service quality required by the positioning initiator, it indicates that the target terminal is rapidly approaching the target area within this period of time, and the positioning cycle interval can be reduced at this time. Increase positioning frequency.

如果目标终端的移动方向朝向目标区域,并且距离L小于定位发起方所要求的定位服务质量中的精度要求,则表明在该时间段内目标终端移动缓慢,此时增加定位周期间隔。If the moving direction of the target terminal is towards the target area, and the distance L is less than the accuracy requirement in the positioning quality of service required by the positioning initiator, it indicates that the target terminal moves slowly during this time period, and the positioning cycle interval is increased at this time.

可以根据距离L与定位发起方所要求的定位服务质量中的精度要求的差值确定增加或缩小定位周期间隔的幅度。The magnitude of increasing or reducing the positioning cycle interval may be determined according to the difference between the distance L and the accuracy requirement in the positioning service quality required by the positioning initiator.

(2)根据距离L和目标终端与目标区域的相对距离S的比较结果及目标终端的移动方向确定本次定位至下次定位的定位周期间隔。(2) According to the comparison result of the distance L and the relative distance S between the target terminal and the target area and the moving direction of the target terminal, determine the positioning cycle interval from this positioning to the next positioning.

如果目标终端的移动方向背离目标区域,并且距离L远小于相对距离S,则表明在该段时间内目标终端移动缓慢,此时可以增加定位周期间隔。If the moving direction of the target terminal deviates from the target area, and the distance L is much smaller than the relative distance S, it indicates that the target terminal moves slowly during this period of time, and the positioning cycle interval can be increased at this time.

如果目标终端的移动方向朝向目标区域,并且距离L大于或等于相对距离S,则表明在该段时间内目标终端快速逼近目标区域,此时,可以缩小定位周期间隔,增加定位频度。If the moving direction of the target terminal is towards the target area, and the distance L is greater than or equal to the relative distance S, it indicates that the target terminal is rapidly approaching the target area within this period of time. At this time, the positioning cycle interval can be reduced and the positioning frequency can be increased.

同样,可以根据距离L与相对距离S的差值确定定位周期间隔缩小或增加的幅度。Likewise, the magnitude of the reduction or increase of the positioning cycle interval can be determined according to the difference between the distance L and the relative distance S.

步骤503:经过调整后的定位周期间隔后,开始下次区域触发定位过程。Step 503: After the adjusted positioning cycle interval, start the next area trigger positioning process.

在本发明中,可以由目标终端计算需要调整的定位周期间隔,也可以由定位服务器计算需要调整的定位周期间隔。当触发条件和计算周期间隔的功能不在同一个实体时需要通知对方定位周期改变。In the present invention, the positioning cycle interval that needs to be adjusted can be calculated by the target terminal, or the positioning cycle interval that needs to be adjusted can be calculated by the positioning server. When the function of the trigger condition and the calculation cycle interval are not in the same entity, it is necessary to notify the other party of the change of the positioning cycle.

如果由目标终端计算需要调整的定位周期间隔,则在目标终端确定需要调整的定位周期间隔后,可以利用SLPL POS INIT消息通知定位服务器调整后的定位周期间隔。比如,当由目标终端计算需要调整的定位周期间隔、并且触发器在网络侧时,需要目标终端将调整后的定位周期间隔通知定位服务器。If the positioning cycle interval to be adjusted is calculated by the target terminal, after the target terminal determines the positioning cycle interval to be adjusted, the SLPL POS INIT message may be used to notify the positioning server of the adjusted positioning cycle interval. For example, when the target terminal calculates the positioning cycle interval that needs to be adjusted, and the trigger is on the network side, the target terminal is required to notify the positioning server of the adjusted positioning cycle interval.

对现有的SUPL POS INIT消息进行扩展,扩展一个参数来表示目标终端修改后的定位周期间隔值。如下表1所示:The existing SUPL POS INIT message is extended, and a parameter is extended to indicate the modified positioning cycle interval value of the target terminal. As shown in Table 1 below:

表1:Table 1:

  参数 parameters   可选状态 optional state   描述 describe   SET Capabilities SET Capabilities   M m   终端性能 Terminal performance   Requested Requested   O o   请求辅助数据 Request auxiliary data

 Assistance Data Assistance Data  Location ID Location ID   M m   终端的cell信息 terminal cell information  Position position   O o   终端的位置 The location of the terminal  SUPLPOS SUPLPOS   O o   所包含的SUPL POS消息 Included SUPL POS message  Ver Ver CVcv   网络发起的情况下需要终端计算的一个SUPL INIT的hash值 In the case of network initiation, a SUPL INIT hash value calculated by the terminal is required  Period Data Period Data   O o   修改后周期参数 Modified cycle parameters

如果由服务器来计算需要调整的定位周期间隔,则在服务器确定需要调整的定位周期间隔后,可以利用SUPLTRIGGERED INIT消息通知目标终端调整后的定位周期间隔。比如,当由定位服务器计算需要调整的定位周期间隔、并且触发器在终端侧时,定位服务器需要通知目标终端调整后的定位周期间隔。If the server calculates the positioning cycle interval that needs to be adjusted, after the server determines the positioning cycle interval that needs to be adjusted, it can use the SUPLTRIGGERED INIT message to notify the target terminal of the adjusted positioning cycle interval. For example, when the positioning server calculates the positioning cycle interval that needs to be adjusted, and the trigger is on the terminal side, the positioning server needs to notify the target terminal of the adjusted positioning cycle interval.

同样,可以对现有的SUPL TRIGGERED INIT消息进行扩展,扩展一个Period Data参数来表示目标终端修改后的定位周期间隔值。Similarly, the existing SUPL TRIGGERED INIT message can be extended, and a Period Data parameter can be extended to indicate the modified positioning period interval value of the target terminal.

具体的定位方法可以采用小区标识的定位方法,也可以采用GPS、EOTD(Enhanced Observed Time Difference,增强型观察时间差)或者OTDOA(Observed Time Difference ofArrival,可观察的到达时间差)等定位方法。The specific positioning method can use the positioning method of the cell identification, or GPS, EOTD (Enhanced Observed Time Difference, enhanced observed time difference) or OTDOA (Observed Time Difference of Arrival, observable time difference of arrival) and other positioning methods.

可以由目标终端根据有效的辅助数据计算出自身的位置(SET-Based方式),并将位置结果返回给定位服务器;或者由定位服务器根据收到的位置测量报告计算出目标终端的位置。The target terminal can calculate its own position according to the valid auxiliary data (SET-Based mode), and return the position result to the positioning server; or the positioning server can calculate the position of the target terminal according to the received position measurement report.

为了方便确定第一次周期定位的开始时间,可以由定位服务器将定位请求方发送的定位请求消息中的目标区域转换为小区列表。对于网络发起的周期性定位,在定位阶段,定位服务器根据目标终端发送的安全用户面定位发起SUPLPOS INIT消息获取目标终端当前所在的小区信息;然后由定位服务器根据目标终端当前所在的小区及目标区域的小区列表信息确定第一次周期定位的开始时间。对于终端发起的周期性定位,在初始阶段,定位服务器将目标区域的小区列表发送给目标终端;然后由目标区域根据其当前所在的小区及所述目标区域的小区列表信息确定第一次周期定位的开始时间。In order to conveniently determine the start time of the first periodic positioning, the positioning server may convert the target area in the positioning request message sent by the positioning requester into a list of cells. For periodic positioning initiated by the network, in the positioning phase, the positioning server initiates a SUPLPOS INIT message to obtain the current cell information of the target terminal according to the secure user plane positioning sent by the target terminal; The cell list information of the cell list determines the start time of the first periodic positioning. For the periodic positioning initiated by the terminal, at the initial stage, the positioning server sends the cell list of the target area to the target terminal; then the target area determines the first periodic positioning according to the cell it is currently located in and the cell list information of the target area start time of .

由上述描述可见,当目标终端移动速度较快或较慢时,会在一个定位周期间隔内移动很长或很短的距离,本发明根据目标终端的移动速度来调整区域触发定位的定位周期间隔。在目标终端移动速度很快时适当缩小定位周期间隔,可以更加及时地确定目标终端的位置,判定其是否满足触发条件;在目标终端移动速度很小时适当增加定位周期间隔,可以有效地节省网络资源。It can be seen from the above description that when the target terminal moves faster or slower, it will move a long or short distance within a positioning cycle interval. The present invention adjusts the positioning cycle interval of the area-triggered positioning according to the moving speed of the target terminal . Appropriately reducing the positioning cycle interval when the target terminal is moving fast can determine the location of the target terminal in a more timely manner and determine whether it meets the trigger conditions; appropriately increasing the positioning cycle interval when the target terminal is moving at a low speed can effectively save network resources .

由于目标终端的移动性,当目标终端处于漫游状态时,上述过程需要由目标终端的H-SLP(归属定位服务器)和V-SLP(拜访定位服务器)来共同完成。网络发起的情况下,SUPL代理向R-SLP(请求定位服务器)发起定位请求,R-SLP找到目标终端的归属H-SLP,H-SLP查找目标终端是否在漫游,如果是处于漫游状态,则通知对应的V-SLP,通过V-SLP、H-SLP和目标终端之间的会话协商确定定位方法等参数,当满足触发条件时触发对目标终端的定位。当定位周期结束时或者满足区域条件时结束整个定位过程。终端发起的情况下,终端向其归属SLP发起定位请求,H-SLP查找路由信息,如果是处于漫游状态,则通知对应的V-SLP,通过V-SLP、H-SLP和目标终端之间的会话协商确定定位方法等参数,当满足触发条件时触发对目标终端的定位。当定位周期结束时或者满足区域条件时结束整个定位过程。Due to the mobility of the target terminal, when the target terminal is in a roaming state, the above process needs to be completed jointly by the target terminal's H-SLP (Home Location Server) and V-SLP (Visitor Location Server). In the case of network initiation, the SUPL agent initiates a location request to the R-SLP (Request Location Server), the R-SLP finds the H-SLP of the target terminal, and the H-SLP checks whether the target terminal is roaming. If it is in the roaming state, then Notify the corresponding V-SLP, determine the location method and other parameters through session negotiation between the V-SLP, H-SLP and the target terminal, and trigger the positioning of the target terminal when the trigger condition is met. When the positioning period ends or the area condition is satisfied, the whole positioning process ends. When initiated by the terminal, the terminal initiates a location request to its home SLP, and the H-SLP searches for routing information. If it is in a roaming state, it notifies the corresponding V-SLP. Through the communication between V-SLP, H-SLP and the target terminal The session negotiation determines the positioning method and other parameters, and triggers the positioning of the target terminal when the trigger condition is met. When the positioning period ends or the area condition is satisfied, the whole positioning process ends.

每次定位过程可以由H-SLP完成,也可以由V-SLP完成,具体实现流程与图5所示类似,在此不再赘述。Each positioning process can be completed by the H-SLP or by the V-SLP. The specific implementation process is similar to that shown in FIG. 5 and will not be repeated here.

参照图6,图6是本发明装置的原理框图:With reference to Fig. 6, Fig. 6 is the functional block diagram of device of the present invention:

本装置包括:定位策略协商单元S1、定位计算单元S2、定位结果通知单元S3、定位周期间隔调整单元S4。The device includes: a positioning strategy negotiation unit S1, a positioning calculation unit S2, a positioning result notification unit S3, and a positioning cycle interval adjustment unit S4.

在周期定位过程的初始阶段,定位策略协商单元S1和目标终端协商定位方法及使用的参数,完成触发定位的协商过程。网络始发的周期性定位过程由定位策略协商单元S1向目标终端发送SUPL INIT(SUPL初始化)消息,通知进行触发定位;目标终端回应SUPL TRIGGERED START(SUPL触发启动)消息,然后定位策略协商单元S1向目标终端回答SUPL TRIGGEREDRESPONSE(SUPL触发响应)消息确认,同时向SUPL Agent发送定位确认消息。在此过程中完成一些参数(比如,定位方法等)的协商,然后进入后面的定位过程。终端始发的周期性定位过程由目标终端上的MLS应用发起针对自己的定位过程。由目标终端向定位策略协商单元S1发送SUPL TRIGGEREDSTART(SUPL触发启动)消息,然后定位策略协商单元S1向目标终端回答SUPL TRIGGERED RESPONSE(SUPL触发响应)消息确认。在此过程中完成一些参数的协商,然后进入后面的定位过程。In the initial stage of the periodic positioning process, the positioning strategy negotiating unit S1 negotiates with the target terminal on the positioning method and parameters used, and completes the negotiation process of triggering positioning. In the periodic positioning process initiated by the network, the positioning policy negotiation unit S1 sends a SUPL INIT (SUPL initialization) message to the target terminal to notify the trigger positioning; the target terminal responds to the SUPL TRIGGERED START (SUPL trigger start) message, and then the positioning policy negotiation unit S1 Reply SUPL TRIGGEREDRESPONSE (SUPL trigger response) message confirmation to the target terminal, and send a location confirmation message to SUPL Agent at the same time. In this process, the negotiation of some parameters (for example, positioning method, etc.) is completed, and then enters into the following positioning process. In the periodic positioning process initiated by the terminal, the MLS application on the target terminal initiates the positioning process for itself. The target terminal sends a SUPL TRIGGEREDSTART (SUPL trigger start) message to the positioning strategy negotiation unit S1, and then the positioning strategy negotiation unit S1 replies to the target terminal with a SUPL TRIGGERED RESPONSE (SUPL trigger response) message confirmation. In this process, the negotiation of some parameters is completed, and then enters the following positioning process.

触发定位的协商过程完成后,在到达定位时刻时,定位计算单元S2计算目标终端的位置,完成第一次定位过程。同时,定位周期间隔调整单元S4根据目标终端的移动速度确定本次定位至下次定位的定位周期间隔,并在到达确定的定位周期间隔后,触发定位计算单元S2对目标终端进行位置计算。After the negotiation process of triggering positioning is completed, when the positioning time is reached, the positioning calculation unit S2 calculates the position of the target terminal to complete the first positioning process. At the same time, the positioning cycle interval adjustment unit S4 determines the positioning cycle interval from this positioning to the next positioning according to the moving speed of the target terminal, and triggers the positioning calculation unit S2 to calculate the position of the target terminal after reaching the determined positioning cycle interval.

为了使定位周期间隔调整单元S4进行正确地决策,可以在该单元中设置速度估计子单元S41、距离计算子单元S42和调整决策子单元S43。In order for the positioning cycle interval adjustment unit S4 to make correct decisions, a speed estimation subunit S41, a distance calculation subunit S42 and an adjustment decision subunit S43 can be set in this unit.

其中,速度估计子单元S41用于估计目标终端的移动速度。在前面对本发明方法的描述中已经提到,可以根据在预定时间内目标终端与一固定目标的相对移动距离计算目标终端的移动速度,或者根据前两次定位过程中获得的目标终端的位置估计目标终端的移动速度;还可以根据在预定时间内目标终端与目标区域的相对移动距离计算目标终端的移动速度。在此不再赘述。Wherein, the speed estimation subunit S41 is used for estimating the moving speed of the target terminal. As mentioned above in the description of the method of the present invention, the moving speed of the target terminal can be calculated according to the relative moving distance between the target terminal and a fixed target within a predetermined time, or according to the position estimation of the target terminal obtained in the previous two positioning processes The moving speed of the target terminal; the moving speed of the target terminal can also be calculated according to the relative moving distance between the target terminal and the target area within a predetermined time. I won't repeat them here.

得到目标终端的移动速度后,由距离计算子单元S42根据该速度估计值计算目标终端在前一次定位周期间隔内移动的距离L,并确定其移动方向。然后由调整决策子单元S43根据距离L进行调整决策。After obtaining the moving speed of the target terminal, the distance calculation subunit S42 calculates the moving distance L of the target terminal in the previous positioning cycle interval according to the estimated speed value, and determines its moving direction. Then the adjustment decision subunit S43 makes an adjustment decision according to the distance L.

调整决策子单元S43可以对距离L和定位请求方所要求的定位服务质量中的精度进行比较,根据比较结果及目标终端的移动方向确定本次定位至下次定位的定位周期间隔:如果目标终端的移动方向背离目标区域,并且距离L小于定位请求方所要求的定位服务质量中的精度要求,则表明在该时间段内目标终端移动缓慢,此时可以增加定位周期间隔,定位周期间隔的增加程度可以依据该终端的移动速度大小来确定。如果目标终端的移动方向朝向目标区域,并且距离L远大于定位发起方所要求的定位服务质量中的精度要求,则表明在该段时间内目标终端快速逼近目标区域,此时可以缩小定位周期间隔,增加定位频度。同样,定位周期间隔的缩小程度可以依据该终端的移动速度大小来确定。The adjustment decision-making subunit S43 can compare the distance L with the accuracy of the positioning service quality required by the positioning requester, and determine the positioning cycle interval from this positioning to the next positioning according to the comparison result and the moving direction of the target terminal: if the target terminal If the direction of movement deviates from the target area, and the distance L is less than the accuracy requirement in the positioning service quality required by the positioning requester, it indicates that the target terminal moves slowly during this time period. At this time, the positioning cycle interval can be increased, and the positioning cycle interval can be increased. The degree can be determined according to the moving speed of the terminal. If the moving direction of the target terminal is towards the target area, and the distance L is much greater than the accuracy requirement in the positioning quality of service required by the positioning initiator, it indicates that the target terminal is rapidly approaching the target area within this period of time, and the positioning cycle interval can be reduced at this time , increase the positioning frequency. Likewise, the reduction degree of the positioning cycle interval can be determined according to the moving speed of the terminal.

另外,还可以在该装置中设置一个相对距离计算单元S5,如图6所示。该相对距离计算单元S5与调整决策子单元S43相连,用于计算目标终端与目标区域的相对距离S,并将相对距离S通知调整决策子单元,使其根据距离L和相对距离S的比较结果及目标终端的移动方向确定本次定位至下次定位的定位周期间隔。如果目标终端的移动方向背离目标区域,并且距离L远小于相对距离S,则表明在该段时间内目标终端移动缓慢,此时可以增加定位周期间隔,定位周期间隔的增加程度可以依据该终端的移动速度来确定。如果目标终端的移动方向朝向目标区域,并且距离L大于或等于相对距离S,则表明在该段时间内目标终端快速逼近目标区域,此时,可以缩小定位周期间隔,增加定位频度。同样,定位周期间隔的缩小程度可以依据该终端的移动速度大小来确定。In addition, a relative distance calculation unit S5 can also be set in the device, as shown in FIG. 6 . The relative distance calculation unit S5 is connected with the adjustment decision-making subunit S43, and is used to calculate the relative distance S between the target terminal and the target area, and inform the adjustment decision-making subunit of the relative distance S, so that it can be adjusted according to the comparison result of the distance L and the relative distance S. and the moving direction of the target terminal to determine the positioning cycle interval from this positioning to the next positioning. If the moving direction of the target terminal deviates from the target area, and the distance L is much smaller than the relative distance S, it indicates that the target terminal moves slowly during this period. At this time, the positioning cycle interval can be increased, and the increase degree of the positioning cycle interval can be based on the terminal's Determine the speed of movement. If the moving direction of the target terminal is towards the target area, and the distance L is greater than or equal to the relative distance S, it indicates that the target terminal is rapidly approaching the target area within this period of time. At this time, the positioning cycle interval can be reduced and the positioning frequency can be increased. Likewise, the reduction degree of the positioning cycle interval can be determined according to the moving speed of the terminal.

在每次周期定位完成后,调整决策子单元S43确定下次定位周期间隔。当经过该间隔后,调整决策子单元S43触发定位计算单元S2对目标终端进行位置计算。After each periodic positioning is completed, the adjustment decision-making subunit S43 determines the next positioning cycle interval. After the interval, the adjustment decision subunit S43 triggers the positioning calculation unit S2 to calculate the position of the target terminal.

可以将本发明装置集成在服务器上。在定位阶段,被定位终端通过SUPLPOS INIT消息将自己的当前位置标识通知该装置。这样,在到达定位时刻后,就可由定位计算单元S2计算目标终端的位置,并根据区域定位触发请求中指定的触发类型判断是否满足触发条件。当不满足触发条件时,通知定位结果通知单元S3结束本次定位;当满足触发条件并且所述区域定位触发请求中未要求得到目标终端的位置时,通知定位结果通知单元S3直接向定位发起方返回触发定位报告;当满足触发条件并且所述区域定位触发请求中要求得到目标终端的位置时,获得定位结果。然后,将目标终端的位置信息发送给SUPL代理。同时,由定位周期间隔调整单元S4根据目标终端的移动速度对定位周期间隔进行调整,如果采用SET-Based方式,定位周期间隔调整单元S4还需要将调整后的定位周期间隔通知目标终端,然后由目标终端根据定位计算单元S2提供的有效的辅助数据计算出自身的位置,并将结果返回给定位计算单元S2;如果采用SET-Assisted方式,则由定位计算单元S2根据收到的目标终端的位置测量报告直接计算出目标终端的位置。The device of the present invention can be integrated on the server. In the positioning phase, the positioned terminal notifies the device of its current location identifier through the SUPLPOS INIT message. In this way, after the positioning time is reached, the positioning calculation unit S2 can calculate the position of the target terminal, and judge whether the trigger condition is satisfied according to the trigger type specified in the area positioning trigger request. When the trigger condition is not satisfied, notify the positioning result notification unit S3 to end this positioning; when the trigger condition is met and the location of the target terminal is not required in the area positioning trigger request, notify the positioning result notification unit S3 directly to the positioning initiator Return the trigger location report; when the trigger condition is met and the location of the target terminal is required in the area location trigger request, the location result is obtained. Then, the location information of the target terminal is sent to the SUPL agent. At the same time, the positioning cycle interval adjustment unit S4 adjusts the positioning cycle interval according to the moving speed of the target terminal. If the SET-Based method is adopted, the positioning cycle interval adjustment unit S4 also needs to notify the target terminal of the adjusted positioning cycle interval, and then The target terminal calculates its own position according to the effective auxiliary data provided by the positioning calculation unit S2, and returns the result to the positioning calculation unit S2; The measurement report directly calculates the position of the target terminal.

还可以将本发明装置集成在终端上,具体实现与上述描述类似,在此不再赘述。The device of the present invention can also be integrated on the terminal, and the specific implementation is similar to the above description, which will not be repeated here.

特别是,还可以将该装置中的不同单元分散集成在服务器和终端上。比如,将定位周期间隔调整单元S4集成在终端上,将其他单元集成在服务器上。这样,每次定位周期间隔的调整由目标终端来完成。如果采用SET-Based方式,则由目标终端根据定位计算单元S2提供的有效的辅助数据计算出自身的位置;如果采用SET-Assisted方式,则定位周期间隔调整单元S4还需要将调整后的定位周期间隔通知定位服务器,当间隔时间到达后,由定位计算单元S2根据收到的目标终端的位置测量报告直接计算出目标终端的位置。In particular, different units in the device can also be distributed and integrated on the server and the terminal. For example, the positioning cycle interval adjustment unit S4 is integrated on the terminal, and other units are integrated on the server. In this way, the adjustment of each positioning cycle interval is completed by the target terminal. If the SET-Based method is adopted, the target terminal calculates its own position according to the effective auxiliary data provided by the positioning calculation unit S2; if the SET-Assisted method is adopted, the positioning cycle interval adjustment unit S4 also needs to adjust the adjusted positioning cycle The interval notifies the positioning server, and when the interval time arrives, the positioning calculation unit S2 directly calculates the position of the target terminal according to the received position measurement report of the target terminal.
