Description

一种定时器控制方法及系统 One kind of timer control method and system

技术领域 FIELD

本发明涉及定时器控制领域,具体涉及一种定时器控制方法及系统。 The present invention relates to a timer control, and in particular, to a timer control method and system.

背景技术 Background technique

对于基于安全的用户平面移动位置业务,目前国际开放移动联盟(OMA,Open Mobile Alliance)已制订出一套基于安全的用户平面移动定位(SUPL,Secure User Plane Location)协议,以对该业务进行全面规范。 For security-based user plane mobile location business, the international Open Mobile Alliance (OMA, Open Mobile Alliance) has developed a set of security-based user plane mobile positioning (SUPL, Secure User Plane Location) protocol, Full to the business specification. 在SUPL协议中,对各实体对应的定时器,以及各定时器的触发和结束条件都进行了明确定义。 In the SUPL protocol, each entity corresponding timers, and triggering and ending conditions timers have been clearly defined. SUPL终端(SET,SUPL Enabled Terminal)对应的定时器分别是:UT1、UT2、UT3和UT4,SUPL定位平台(SLP,SUPL LocationPlatform)对应的定时器分别是:ST1、ST2、ST3和ST4,SUPL位置计算中心(SPC,SUPL Positioning Centre)对应的定时器是PT1,请求SUPL定位平台(R-SLP,Requesting SUPL Location Platform)对应的定时器是RT1。 SUPL terminal (SET, SUPL Enabled Terminal) corresponding to the timer are: UT1, UT2, UT3 and UT4, SUPL Location Platform (SLP, SUPL LocationPlatform) corresponding to the timer are: ST1, ST2, ST3 and ST4, SUPL location computing Center (SPC, SUPL positioning Centre) corresponding timer is PT1, requesting SUPL location platform (R-SLP, requesting SUPL Location platform) corresponding timer is RT1. 各定时器分别应用于SUPL过程的不同阶段,例如:UT1触发条件是:SET发送SUPL开始(Start)消息,结束条件是:SET收到SUPL响应(Response)消息,UT1的定时时长是10秒,当UT1超时时,SET会给SLP发送SUPL结束(End)消息,同时释放自身占用的本次对话资源。 Timers are used in different stages of the SUPL procedure, for example: UT1 triggering condition is: SET transmits a SUPL START (Start) message, ending with the proviso that: SET received SUPL RESPONSE (the Response) message, when the timing of UT1 length is 10 seconds, when UT1 timeout, SET will SLP sends a SUPL end (end) messages, while the release of this dialogue resource itself occupied.

定时器可以避免在业务进行过程中,当请求方发送了请求消息后,响应方由于对该请求消息的响应超时而导致的对话吊死,减少资源的浪费。 Timers can be avoided during the course of business, when the requester sends a request message, a response interlocutor since the response to the request message timeout caused by hanging, reduce waste of resources. 具体地,当响应方没有释放本次对话,但由于内部处理或其它原因导致响应超时,且请求方发现了自身的等待定时器超时时,那么,请求方会及时给响应方发送SUPL结束消息,以通知响应方释放本次对话,同时自身释放本次对话。 Specifically, when the responder does not release this dialogue, but the internal processing or other causes response timeout, and the request discovery when its timer expires, then the requester will promptly to the responder sends a SUPL END message, to inform the responder release of this dialogue, while their release this dialogue.

上述处理虽然可在一定程度上避免资源的浪费,但是同时也会引起以下缺点:1、在响应方有能力处理本次业务时,异常结束本次业务。 The above-mentioned process, although to avoid waste of resources to some extent, but will also cause the following disadvantages: 1, when the responder is capable of handling this business, abnormal end of this business. 响应方可能由于当前网络负荷较大等原因,暂时无法处理本次业务,但若请求方稍微等待较短时间,响应方就很有可能处理本次业务。 The responder may be due to network loading and other reasons this is temporarily unable to handle this traffic, but if the requester is slightly shorter wait time, the responder is likely process for the business. 且,业务异常结束,会给用户造成服务质量不好的印象。 Moreover, the business ends abnormally, the user will cause the quality of service is not good impression.

2、请求方可能会进行二次或多次业务申请,而此时响应方可能仍然无法处理该业务,导致该业务继续失败,浪费了大量资源。 2, the requesting party may be twice or more business applications, at a time when the responder may still be unable to handle the business, resulting in the business continue to fail, wasting a lot of resources.

3、标准规范中的定时器时长都为建议值,这些建议值并不能适用于所有业务对话。 3, the standard specification of the timer length are recommended values ​​These recommendations do not apply to all business conversation.

具体实施方式 Detailed ways

本发明的核心思想是:请求方给响应方发送请求消息的同时,启动等待定时器;响应方收到该消息后,启动监测定时器,该监测定时器的时长小于等待定时器的时长,在响应方未处理完该请求消息、但监测定时器超时时,响应方给请求方发送定时器重启消息;请求方收到该消息后,重新启动等待定时器,以继续等待响应方的响应。 The core idea of ​​the invention is: while the requester to the responder transmits a request message, start the wait timer; the responder receives the message, starts the monitoring timer, when the monitoring timer length less than the long wait timer in responder untreated completion of the request message, but monitor the timer expires, the responder to the requestor send timer restart message; the requesting party receives the message, re-start wait timer to continue waiting for a response of the responder.

下面结合附图及具体实施例对本发明再作进一步详细的说明。 Specific embodiments of the present disclosure will be described in further detail below in conjunction with the accompanying drawings and.

图1是本发明提供的定时器控制的系统框图,如图1所示,其具体包括:请求方设备:用于给响应方设备发送请求消息,同时启动等待定时器;用于接收响应方设备发送的定时器重启消息,并重新启动等待定时器。 FIG. 1 is a system block diagram of the present invention provides a timer control, shown in Figure 1, which comprises: requesting device: means to the responder device transmits a request message, and start wait timer; for receiving a response side device send timers restart message, and restart the wait timer.

进一步地,请求方设备用于在收到响应方设备发送的定时器重启消息后,给响应方设备返回定时器重启响应。 Further, the requesting device after receiving the timer in response sent by the party restart message to the responder device returns timer restart response.

响应方设备:用于接收请求方设备的请求消息,同时启动时长小于请求方设备的等待定时器时长的监测定时器;用于在监测定时器已超时、但未处理完该请求消息时,给请求方设备发送定时器重启消息。 Responder equipment: means for receiving requestor device request message, and start time length is less than the requestor device wait timer duration monitoring timer; for monitoring the timer has timed out, but not finished processing the request message, give requesting device send timer restart message.

进一步地,响应方设备用于接收请求方设备发送的定时器重启响应。 Further, the response side device for receiving a request timer device transmits a square restart response.

在本发明中,只要一设备发起请求并等待对方设备的响应,该设备就可称为请求方设备;同样,只要一设备接收请求并需给发送该请求的对方设备返回响应,该设备就可称为响应方设备。 In the present invention, when a device initiates a request and waits for a response of the other device, the device can be called requestor device; Similarly, as long as a device receives the request and the need to send the request to the other device returns a response, the device can be It referred responder device.

图2是本发明提供的定时器控制的流程图,如图2所示,其具体步骤如下:步骤201:请求方给响应方发送请求消息,同时启动等待定时器。 FIG 2 is a flowchart of the present invention provides a timer control, as shown in FIG. 2, the specific steps are as follows: Step 201: the requestor to the responder transmits a request message, and start the wait timer.

本发明中的请求方可以是SET或SLP等,对应地,响应方可以是SLP或SET等。 In the present invention, the requester may be other SET or SLP, correspondingly, the responder may be like SLP or the SET. 若有多个请求方或多个响应方,且所有请求方和所有响应方之间都可实现通信,那么可以采用本发明提供的定时器控制方法,实现所有请求方的定时器控制。 If a plurality of requestor or more responders, and communication can be realized, the present invention provides a method of controlling the timer may be employed to realize the timer control all requestor among all parties and all responder requests.

步骤202:响应方收到该消息,设定并启动监测定时器,同时对该消息进行处理。 Step 202: the responder receives the message, setting and starts monitoring the timer, while the message is processed.

监测定时器时长要小于请求方的等待定时器时长。 Long time monitoring timer length is less than the wait timer requesting party. 响应方可通过以下两种方式得知请求方的等待定时器时长:一、自身保存的由系统设定的默认等待定时器时长;二、响应方预测的等待定时器时长。 In response to only the following two ways long wait timer when the requesting party that: a long waiting timer own default settings stored by the system; second, long wait timer responder predicted.

步骤203:响应方判断该消息是否处理完毕,若是,执行步骤204;否则,执行步骤205。 Step 203: the responder determines whether the message has been processed, if yes, perform step 204; otherwise, step 205 is executed.

步骤204:响应方给请求方返回响应消息,同时清除监测定时器,本流程结束。 Step 204: the responder to the requestor returns a response message, and clear the monitor timer, and the flow ends.

同样,请求方收到该响应消息后,清除等待定时器。 Similarly, the requesting party after receiving the response message, clears the wait timer.

步骤205:响应方判断监测定时器是否超时,若是,执行步骤206;否则,继续处理该消息,并返回步骤203。 Step 205: responder judge monitoring timer expires, and if so, step 206 is executed; otherwise, continue to process the message and returns to step 203.

步骤206:响应方给请求方发送定时器重启消息。 Step 206: the responder to the requestor send timer restart message.

监测定时器超时,表明响应方没有及时给请求方返回响应消息。 Monitoring timer times out, indicating that the responder did not return a response message to the requester.

定时器重启消息包含当前对话标识(ID)、需重新设置的定时器ID即等待定时器ID,还可以包括定时器重新设置时长。 Restarting the timer message containing the current session identifier (ID), re-set the timer for an ID, i.e. wait timer ID, it can further include a reset timer duration.

定时器重启消息可采用现有技术中请求方和响应方支持的发送方式发送。 Timer restart message can be transmitted transmission mode prior art request and the responder support.

响应方在发送定时器重启消息时,可同时设定一等待重启响应时长,若该时长已过,仍未收到请求方返回的定时器重启响应,就重新给请求方发送该定时器重启消息。 Responder in the transmission timer when the restart message, which can be set long a wait for the restart response, if the duration has elapsed, not received the timer restarted in response to the request is returned from it again to the requesting party sends the timer restart message .

步骤207:请求方收到该定时器重启消息,重新启动等待定时器,以重新等待响应方的响应消息。 Step 207: the requesting party receives the message timer is restarted to restart the wait timer to wait for a response message back to the responder.

发送定时器重启消息后,响应方继续正常处理该请求消息。 Send timer restart message, the responder continues normal processing of the request message.

请求方收到响应方发送的定时器重启消息后,可以给响应方返回一个定时器重启响应,表示收到定时器重启消息,定时器重启响应包含对话ID。 After the request has received a timer in response sends restart messages can be to the responder returns a timer is restarted in response to acknowledge the receipt of the timer restart message, the timer restart response includes session ID.

重新设置的等待定时器时长,可以是响应方在定时器重启消息中设定的,也可以是请求方根据自身情况设定的。 Long waiting timer is reset to be a responder to set the timer to restart the message may be a requestor setting according to their own situation.

若重启的等待定时器超时后,响应方仍未处理完该消息,那么,响应方可再次发送定时器重启消息,请求方可再次重启等待定时器。 After If restart timer expires, the responder has not yet finished processing the message, then the response can send timer again restart message, request before restarting the standby timer again.

在实际应用中,根据自身的不同情况,请求方在收到定时器重启消息后,也可能不重设等待定时器,且在原设置的等待定时器超时后,仍没收到响应方的响应消息时,给响应方发送释放对话消息,同时自身释放本次对话;或者,在收到定时器重启消息后,直接释放本次对话,并给响应方发送释放对话消息。 In practical applications, according to their different circumstances, the requesting party in receipt timer restart message, or may not reset the waiting timer, and the original set timer expires after, still have not received the responder response message , to the responder transmits a release dialog messages, while self releasing the dialogue; or, after receiving the timer restart message, direct release of this dialogue, and to the responder sends a release dialog message.

为了更清楚地描述本发明,现给出一个具体的例子:SET要发起一个自定位过程,向SLP发送SUPL开始消息,同时启动定时器UT1,UT1的时长为10秒;SLP收到该消息,启动监测定时器,且设定该监测定时器时长为9秒;在监测定时器超时时,SLP仍未处理完SUPL开始消息,此时SLP给SET返回定时器重启消息,消息中包含本次对话ID、定时器ID:UT1、以及定时器重设时长:3秒;SLP收到该消息后,重新设置UT1时长为3秒,继续等待SLP返回的SUPL响应。 In order to more clearly describe the present invention, are given a concrete example: SET to initiate a self-aligning process, the SLP sends a SUPL START message, start the timer UT1, UT1 length of time is 10 seconds; SLP receives the message, starts monitoring the timer, and setting the monitoring timer to 9 seconds; at the monitoring timer expires, SLP not processed SUPL sTART message, then SLP to the sET returns timer restart message, the message comprising this dialogue ID, the timer ID: when UT1, and a timer reset length: 3 seconds; the SLP receives the message, re-set UT1 duration 3 seconds, continues to wait for the SUPL SLP response returned.

以上所述仅为本发明的过程及方法实施例,并不用以限制本发明,凡在本发明的精神和原则之内所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。 The above are only embodiments of the process and methods of the present invention, not intended to limit the present invention, where any modifications within the spirit and principle of the present invention made, equivalent replacement, or improvement, should be included in the present invention. within the scope of protection.
