Description

一种集群通信系统的组派接方法、通信系统及存储介质 【技术领域】
本申请涉及通信技术领域，具体涉及一种集群通信系统的组派接方法、通信系统及存储介质。
【背景技术】
在国内专网通信系统(如警用数字集群(Police Digital Trunk，PDT)和长期演进(Long Term Evolution，LTE)等)建设过程中，会遇到某些地方已经建设了老的专网系统(如移动专用集群(Mobile PrivateTrunking，MPT)和泛欧集群无线电(Trans European Trunked Radio，Tetra)等)并实际在用，这样就会产生新的专网通信系统和老的专网通信系统之间的互联互通的需求。现有建设的专网通信系统中一般有对应的手台、车台以及调度台，车台和手台一般通过无线基站的方式接入到专网通信系统，调度台一般是通过网络协议(Internet Protocol，IP)链路的方式接入到集群系统。
本申请的发明人在长期研发中发现，目前存在的老集群通信系统通常是制造商专用的系统，该系统是私有的、封闭式的，并且不对其他厂商开放，因此无法直接接入老集成通信系统的系统服务器，目前国内大多数新的通信系统和老的通信系统进行互联互通的方案中，如果需要多个组进行互联互通，就需要在互联互通网络内增加多个车台信令处理设备，并将多个车台接入到老的通信系统下，部署时则需要将每个车台放入到不同的基站下，由于每个车台仅工作在一个信道上且只能用于一个互联组，因而此方案不能实现动态互联，当互联组较多，实际并发量不大时，不能重复利用车台资源进行呼叫，耗费硬件资源，随着互联组的增加，需要不断增加硬件设备，呼叫时需要占用一个基站的一个信道资源；且部署困难，需要将不同的车台设备部署到不同的基站下，否则容易将一个基站的信道资源耗光；维护困难，当互联出故障时，需要去基站下进行设备检查。

【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。其中：

【具体实施方式】
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性的劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
目前国内大多数新通信系统和老通信系统进行互联互通的方案，一般是通过开发一种特殊的车台信令处理设备，并在该设备下挂载一个车台，通过对车台写频的方式，将该车台加入到老通信系统对应的组下，实现一个组的互联互通，如图1所示；如果需要多个组进行互联互通，就需要在互联互通网络内增加多个车台信令处理设备，并将多个车台接入到老通信系统下；一个车台对应一个老通信系统的组，分别和新通信系统下的组进行互通；如果需要100个组互通，就需要100个车台和车台信令处理设备，由于在同一个基站下部署车台和车台信令处理设备会将基站的信道资源耗光，因而需要将每个车台放入到不同的基站下；此方案不能实现动态互联，无法重复利用车台资源进行呼叫，耗费硬件资源，且部署和维护困难。
例如，Tetra系统的老集群通信系统一般可包括基站、系统服务器、调度台和通信终端。当通信终端发起呼叫时，基站接收到呼叫请求，并且将该呼叫消息转发给系统 服务器，由系统服务器处理该呼叫请求。调度台可通过系统服务器监听特定的呼叫，当相应呼叫发生时系统服务器可通知调度台，并且调度台可用于发起或接收呼叫。例如车台和手台的通信终端一般通过无线方式利用基站接入到专网通信系统，调度台一般是通过IP链路的方式接入到集群系统服务器。老集群通信系统通常是制造商专用的系统，该系统是封闭式的，并且不对其他厂商开放，因此无法直接接入老集成通信系统的系统服务器，然而在集成通信系统中的调度台的控制接口一般是对用户开放的以便于实现用户功能的定制。本申请的实施例灵活利用老集群通信系统下的调度台，并作为互联互通的资源。在一些实施例中，还通过将部分调度台作为监听调度台，部分调度台作为语音调度台，监听调度台监听到老的通信系统中呼叫事件后，选择空闲调度台加入到该监听到的呼叫中，语音调度台建立语音链路进行语音的传递，呼叫结束后释放该语音链路，通过这种方式实现呼叫调度台的重复利用，从而达到了动态互联的效果。
在本申请实施例中提及的集群通信系统包括但不限于PDT系统、Tetra系统、集成数字增强型网络(Integrated Digital Enhanced Network，iDEN)系统、开放式集群架构(Global Open Trunking Architecture，GOTA)或华为的GT800系统等。
参阅图2，图2是本申请提供的集群通信系统一实施例的结构示意图，该通信系统20可包括互联服务器21、系统服务器22和至少一个语音调度台23。
互联服务器21连接到与集群通信系统之外的其他集群通信系统，并且可用于接收该其他集群通信系统中的第一通信终端24向目标组发起的组呼相关联的第一建立呼叫消息，其中，目标组包括多个第二通信终端25，并且当互联服务器21接收到第一建立呼叫消息时，建立第一通信终端24与互联服务器21之间的呼叫连接、从至少一个语音调度台23中选择空闲的语音调度台23作为服务接入点，并向空闲的语音调度台23发送第二建立呼叫消息，其中，第二建立呼叫消息包含目标组的组呼号码。
互联服务器21与其他设备的连接能够以任何有线或无线连接方式实现，并且为了便于客户应用定制，集群通信系统中的调度台通常配置有相应的接口用于接入调度台并对调度台进行操作，因此互联服务器21可以根据不同的集群通信系统采用不同的通信协议接入调度台。可以理解地，采用相应的通信协议接入调度台是本领域技术人员所通知的技术，在此不做赘述。
系统服务器22用于在语音调度台23与集群通信系统中目标组中的第二通信终端25之间建立连接；在集群通信系统中该系统服务器22可用于处理终端的通信业务，例如，从诸如调度台、手台或车台等通信终端接收呼叫，并且将该呼叫转发给目的通信终端，使得集群通信系统中的通信终端通过系统服务器22彼此连接。同时，可以在系统服务器22中对呼叫规则进行配置，例如，可以将特定的组呼配置成当接收到相应的组呼号码呼叫时通知特定的调度台。
语音调度台23用于当接收到第二建立呼叫消息时，在空闲的语音调度台23和互联服务器21之间建立呼叫连接，并通过系统服务器22与集群通信系统中目标组中的第二通信终端25建立呼叫连接用于收发语音。
在语音调度台23和集群通信系统中的目标组之间建立呼叫连接可包括语音调度台23通过为该目标组中的第二通信终端25提供服务的系统服务器22与该目标组建立呼叫连接以进行语音通话。
通过利用互联服务器21控制多个语音调度台23进行语音呼叫；在互联服务启动后，能够实现第一通信终端24和目标组中的第二通信终端25之间进行组呼时，动态的选择语音调度台23呼叫目标组，从而能够实现呼叫业务，充分利用资源。
可以理解地，除上述组成部件之外，集群通信系统也可能包括现有技术中的其他部分，例如，用于从/向通信终端接收/发射无线信号的基站以及用于中继信号的中转台等等，但省略这些其他部分并不妨碍本领域技术人员对于本申请实施例的理解，在此不做赘述。
参阅图2和图3，图3是本申请提供的用于集群通信系统的组派接方法第一实施例的流程示意图，该方法应用于上述实施例中的集群通信系统，包括以下步骤：
步骤31：互联服务器21接收来自集群通信系统之外的其他集群通信系统的第一建立呼叫消息。
第一建立呼叫消息与其他集群通信系统中的第一通信终端24向目标组发起的组呼相关联，目标组包括多个第二通信终端25。
可以理解地，目标组中的第二通信终端25可以包括该集群通信系统中的通信终端，也可以包括其他集群通信系统中的通信终端。集群通信系统和其他集群通信系统中目标组的组呼号码可以不同，可以在互联服务器21中存储有集群通信系统中目标组的组呼号码和其他集群通信系统中目标组的组呼号码的对应关系。
第一通信终端24向目标组发起组呼，将第一建立呼叫消息发送给互联服务器21，以请求与集群通信系统中的目标组建立通话。
步骤32：当互联服务器21收到第一建立呼叫消息时，建立第一通信终端24与互联服务器21之间的呼叫连接、从至少一个语音调度台23中选择空闲的语音调度台23作为服务接入点、并且向空闲的语音调度台23发送第二建立呼叫消息。
系统服务器22中存储有集群通信系统的目标组的对应信息，互联服务器21在接收到第一建立呼叫消息时，从至少一个语音调度台23中选择一个空闲的语音调度台23发起呼叫，并向该语音调度台23发送第二建立呼叫消息，第二建立呼叫消息包含目标组的组呼号码，以将目标组呼叫起来。
可以在互联服务器21中或是与互联服务器21耦合的其他设备中存储指示至少一个语音调度台23是否空闲的状态信息，以便于互联服务器21可以从至少一个语音调度台23中选择一个空闲的语音调度台23。可以理解地，本申请的实施例也可以通过其他方式确定语音调度台23的状态，例如，接收至少一个语音调度23的指示其状态信息的消息来确定语音调度台23的状态，在此不限制其具体实现方式。
进一步地，互联服务器21可以将其他集群通信系统中目标组的组呼号码转换成集群通信系统中目标组的组呼号码，并查找集群通信系统中目标组对应的第二通信终端25，最终建立起集群通信系统中目标组中的第二通信终端25与其他集群通信系统中目标组中的第一通信终端24的呼叫连接。
步骤33：当空闲的语音调度台23接收到第二建立呼叫消息时，在空闲的语音调度台23和互联服务器21之间建立呼叫连接，并且空闲的语音调度台23通过系统服务器22与集群通信系统中目标组中的第二通信终端25建立呼叫连接用于收发语音。
语音调度台23接收到第二建立呼叫消息后，建立互联服务器21与语音调度台23之间的呼叫连接，并建立目标组与系统服务器22之间的连接，使得目标组中的第二通 信终端25可以与第一通信终端24进行通话，从而实现集群通信系统之间的呼叫业务。

步骤46：语音调度台51判断第二建立呼叫消息中是否携带监听标识，若不携带监听标识，则语音调度台53发送建立呼叫消息给目标组。
语音调度台53在接收到互联服务器51发送的第二建立呼叫消息后，检查该第二建立呼叫消息是否携带监听标识，如果不携带监听标识，则语音调度台53会发起呼叫，即通过系统服务器52发送建立呼叫消息给目标组中的第二通信终端55。
步骤47：目标组分别通过语音调度台53和监听调度台56发送建立成功消息和监听组呼消息给互联服务器51。

互联服务器51判断当前是否存在组呼，如果当前存在组呼，则不做任何处理，第一通信终端54和目标组中的多个第二通信终端55利用互联服务器51、语音调度台53以及系统服务器52进行语音消息的传送。
在一个具体的实施例中，为了实现了PDT与Tetra的组的动态互联，建立一个通信系统，该通信系统的系统服务器52为Tetra连接服务器(Tetra Connectivity Server，TCS)，并使用Tetra语音网关(Tetra Voice Gateway，TVG)作为语音设备57接入；调度台的语音是通过IP的方式传给TVG，TVG通过E1协议(欧洲的30路脉码调制)连接到Tetra的数字交换机以进行语音的传递，Tetra的数字交换机为每个调度台的语音资源都创建了一个控制器，每一个控制器控制调度台的语音通话路数，一个调度台能够实现一路下呼语音和多路监听语音。由于E1协议时隙的限制，通过该TVG设备传递的语音数量有限，最多可以实现60个调度台同时进行呼叫传递语音，当配置200个组进行互联互通时，最多实现60路并发呼叫。
通过利用集群通信系统中的调度台作为互联互通的资源实现多路动态并发，一个调度台(监听调度台56)作为监听接口，多个调度台(语音调度台53)作为语音接口；利用监听接口监听到集群通信系统内的呼叫，利用语音接口进行实际的语音呼叫；在集群通信系统有限制的情况下，使用更少的语音链路实现更多的组进行互联；可以同时实现多个组互联，全部使用有线传输语音，减少了设备的使用量，避免使用空口传语音引起的丢字问题，节省硬件资源，且便于后期的维护。
参阅图5和6，图6是本申请提供的用于集群通信系统的组派接方法第三实施例的流程示意图，该实施例为第一通信系统终端54挂断与集群通信系统中目标组之间的组呼，包括以下步骤：
步骤61：第一通信设备54通过语音调度台53发送第一呼叫挂断消息给互联服务器51。
在第一通信终端54与集群通信系统中的多个第二通信终端55通话了一段时间之后，第一通信终端54的用户想要结束通话时，第一通信终端54接收到挂断组呼的指令，发送第一呼叫挂断消息发送给互联服务器51。
步骤62：互联服务器51接收到第一呼叫挂断消息时，发送释放话权消息给语音调度台53。
第一通信终端54挂断呼叫后，将第一呼叫挂断消息上报给互联服务器51，互联服务器51向语音调度台53发送释放话权请求。
步骤63：语音调度台53判断目标组中的第二通信终端55是否具有话权；若具有话权，则目标组在呼叫的空闲时间超过预设时间时挂断呼叫，并将呼叫挂断消息发送给互联服务器51，语音调度台53取消监听目标组。
语音调度台53在接收到释放话权消息后，判断目标组的调度台是否有话权，如果具有话权，则将该调度台的话权释放，发送释放话权消息给目标组中的第二通信终端55；并在空闲超时的时候，分别将呼叫挂断消息通过语音调度台53和监听调度台56发送给互联服务器51，语音调度台53取消监听集群通信系统中的目标组。
集群通信系统中组呼空闲超时后会自动挂断该组的呼叫，即在无人讲话的情况下空闲预设时间后，就会挂断组呼，并发送呼叫挂断消息给语音调度台53和监听调度台56，这两个呼叫挂断消息都会上报给互联服务器51，但是互联服务器51不做处理，且语音调度台53在接收到呼叫挂断消息后负责取消监听，发送取消监听消息给集群通信系统，以实现组呼的挂断。
参阅图5和7，图7是本申请提供的用于集群通信系统的组派接方法第四实施例的 流程示意图，该实施例为第一通信终端54挂断与集群通信系统中目标组之间的组呼，包括以下步骤：
步骤71：第一通信设备54发送第二呼叫挂断消息给互联服务器51。
互联服务器51接收到第一通信设备54发送的第二呼叫挂断消息。
步骤72：互联服务器51接收到第二呼叫挂断消息时，发送释放话权消息给语音调度台53。
互联服务器51根据第二呼叫挂断消息发送释放话权请求给语音调度台53。
步骤73：语音调度台53判断目标组中的第二通信终端55是否具有话权。
步骤74：在呼叫的空闲时间未超过预设时间且有第二通信终端55申请话权时，通过监听调度台56将话权消息发送给互联服务器51。
语音调度台53判断集群通信系统中的目标组是否具有话权，若具有话权，在集群通信系统中的目标组在呼叫的空闲时间未超过预设时间且有第二终端申请55话权时，通过监听调度台56将话权消息发送给互联服务器51。
由于第一通信终端54发送呼叫挂断消息后，互联服务器51只是给集群通信系统中的目标组发送话权释放；如果集群通信系统中目标组的空闲时间并未达到预设时间，且集群通信系统中有第二通信终端55申请了话权，通过监听调度台56上报话权消息给互联服务器51，申请话权，此时互联服务器51检查到第一通信终端54的通话组已经挂断，负责再次拉起与第一通信终端54之间的通话。
步骤75：互联服务器51接收到话权消息时，发送第三建立呼叫消息给第一通信终端54，在第一通信终端54和互联服务器51之间建立呼叫连接用于收发语音。
互联服务器51在接收到监听调度台56转发的话权消息之后，发送第三建立呼叫消息给第一通信终端54，第一通信终端54返回建立成功消息给互联服务器51，第一通信终端54和集群通信系统中的目标组重新开始通话。
在第一通信终端54发送挂断请求时，集群通信系统在检测到未空闲超时，且有第二通信终端55申请话权时，重新建立与第一通信终端54的通话，实现了组呼的再次建立。
参阅图8，图8是本申请提供的集群通信系统另一实施例的结构示意图，该通信系统80可包括互联服务器81、系统服务器82、至少一个语音调度台83和监听调度台86。
监听调度台86用于监听集群通信系统内的第二通信终端85向目标组发起的组呼，并且当监听调度台86监听到第二通信终端85向目标组发起组呼时，向互联服务器81发送第四建立呼叫消息，其中，第四建立呼叫消息包含集群通信系统中目标组的组呼号码，目标组包括多个通信终端。
互联服务器81与集群通信系统之外的其他集群通信系统连接，用于在接收到第四建立呼叫消息时，与其他集群通信系统中目标组的通信终端建立呼叫连接、从至少一个语音调度台83中选择空闲的语音调度台83作为服务接入点、并且向空闲的语音调度台83发送第五建立呼叫消息。
系统服务器82用于在语音调度台83与集群通信系统中目标组中的通信终端之间建立连接。
语音调度台83用于在接收到第五建立呼叫消息时，在空闲的语音调度台83和互联服务器81之间建立呼叫连接，并且空闲的语音调度台83通过系统服务器82与第二 通信终端85建立呼叫连接用于收发语音。
可以理解地，相同的目标组在派接的两个集群通信系统中可以具备不同的组呼号码，即集群通信系统的目标组的组呼号码和其他集群通信系统的目标组的组呼号码可以存在对应关系，具体地，互联服务器81中存储有集群通信系统中目标组的组呼号码和其他集群通信系统中目标组的组呼号码的对应关系；当集群通信系统中的第二通信终端85呼叫集群通信系统中的目标组时，互联服务器81将集群通信系统中目标组的组呼号码转换成其他通信系统中目标组的组呼号码，并查找其他集群通信系统中目标组对应的第一通信终端84，最终建立起集群通信系统中目标组中的第二通信终端85与其他集群通信系统中目标组中的第一通信终端84的呼叫连接。
通过利用互联服务器81控制用于监听的监听调度台86，以监听集群通信系统系统内的呼叫事件，还控制多个语音调度台83进行语音呼叫；在互联服务启动后，利用多个语音调度台83和监听调度台86之间的协作，能够实现第二通信终端85和目标组之间进行组呼时，动态的选择语音调度台83呼叫目标组，从而能够实现呼叫业务，充分利用资源。
参阅图8和图9，图8是本申请提供的用于集群通信系统的组派接方法第五实施例的流程示意图，该方法应用于上述实施例中的集群通信系统，包括以下步骤：
步骤91：当监听调度台86监听到集群通信系统内的第二通信终端85向目标组发起组呼时，向互联服务器81发送第四建立呼叫消息。
互联服务器81用于与除集群通信系统之外的集群通信系统连接，监听调度台86用于监听集群通信系统内的第二通信终端85发起的组呼，第四建立呼叫消息包含其他集群通信系统中目标组的组呼号码。
如本领域技术人员所知的，集群通信系统中的系统服务器82可配置成当接收到特定的组呼号码时向特定的调度台发出通知。因此，可以通过对系统服务器82进行相应的配置，来使得监听调度台86能够监听到集群通信系统内的第二通信终端85向集群通信系统中的目标组发起组呼。
可以理解地，集群通信系统和其他集群通信系统中目标组的组呼号码可以不同，互联服务器81中存储有集群通信系统中目标组的组呼号码和其他集群通信系统中目标组的组呼号码的对应关系。
步骤92：当互联服务器81接收到第四建立呼叫消息时，与其他集群通信系统中目标组中的第一通信终端84建立呼叫连接、从至少一个语音调度台83中选择空闲的语音调度台83作为服务接入点、并且向空闲的语音调度台83发送第五建立呼叫消息。
系统服务器82中存储有其他集群通信系统的目标组的对应信息，互联服务器81选择一个空闲的语音调度台83发起呼叫。
步骤93：当空闲的语音调度台83接收到第五建立呼叫消息时，在空闲的语音调度台83和互联服务器81之间建立呼叫连接，并且空闲的语音调度台83通过系统服务器82与第二通信终端85建立呼叫连接用于收发语音。
在第二通信终端85发起呼叫后，利用监听调度台86实现将第三建立呼叫消息传递给互联服务器81，互联服务器81选择空闲的语音调度台83发起呼叫，使得第二通信终端85和目标组之间建立呼叫，能够动态的选择语音调度台83发起呼叫，从而实现动态跨系统的呼叫业务。
参阅图8和图10，图10是本申请提供的用于集群通信系统的组派接方法第六实施例的流程示意图，该实施例为第二通信终端85请求建立与其他集群通信系统中目标组之间的组呼，包括以下步骤：
步骤101：当监听调度台86监听到第二通信终端85向目标组发起组呼时，向互联服务器81发送第四建立呼叫消息。
第四建立呼叫消息包含其他集群通信系统中的目标组的组呼号码；第二通信终端85发起呼叫，由于监听调度台86在服务启动时监听了该组的呼叫消息，所以有监听呼叫消息会上报给监听调度台86，监听调度台86接收到该第四建立呼叫消息后上报给互联服务器81。
步骤102：当互联服务器81收到第四建立呼叫消息时，建立第二通信终端85与互联服务器81之间的呼叫连接。
互联服务器81在接收到第四建立呼叫消息之后，返回一个应答消息，即发送监听应答消息给监听调度台86，然后监听调度台86将接收到的监听应答消息通过系统服务器82发送给第二通信终端85。
步骤103：互联服务器81从至少一个语音调度台83选择空闲的语音调度台83。
互联服务器81将目标组呼叫起来后，在至少一个语音调度台83中选择一个空闲的语音调度台83发起呼叫。
步骤104：互联服务器81向空闲的语音调度台83发送第五建立呼叫消息。
互联服务器81将第五建立呼叫消息发送给目标组，同时互联服务器81还将第五建立呼叫消息发送给语音调度台83，该第五建立呼叫消息包含目标组的组呼号码和监听呼叫标识。
步骤105：语音调度台83根据第五建立呼叫消息发送第六建立组呼消息给目标组。
语音调度台83接收到互联服务器81的发送的第五建立呼叫消息后，会发起对该呼叫组的监听，通过系统服务器82发送第六建立组呼消息给第二通信终端85。
步骤106：第二通信终端85发送呼叫应答消息给语音调度台83。
步骤107：语音调度台83判断第五建立呼叫消息中是否携带监听标识，若携带监听标识，则语音调度台83在接收到第二通信终端85发送的监听呼叫消息时，发送建立成功消息给互联服务器81和第二通信终端85。
第二通信终端85将通过系统服务器82返回一个呼叫应答消息给语音调度台83，语音调度台83判断接收到的第五建立呼叫消息是否携带监听标识，如果携带监听标识，则等待第二通信终端85通过系统服务器82上报监听呼叫消息，并在接收到第二通信终端85发送的监听呼叫消息之后，将建立成功消息分别发送给第二通信终端85和互联服务器81。
在互联服务器81接收到语音调度台83发送的建立成功消息后，第二通信终端85可以利用语音设备87收发语音，并通过语音调度台83和互联服务器81将语音消息传送给目标组。
对于其他集群通信系统而言，一个调度台可以实现多路并发呼叫；对于集群通信系统而言，使用多个调度台进行连接，监听调度台86连接系统服务器82，进行呼叫消息的监听，语音调度台83同时连接系统服务器82和语音设备87；互联服务器81绑定多个第二通信终端85和第一通信终端84；在服务启动后，通过监听调度台86对这些 组发起监听，监听调度台86监听到呼叫消息后，通知互联服务器81，互联服务器81选择空闲的语音调度台83发起呼叫；利用多个调度台之间的协作，实现目标组和第二通信终端85之间进行组呼时，动态的选择语音调度台83呼叫目标组，能够实现跨系统的呼叫业务。
参阅图8和图11，图11是本申请提供的用于集群通信系统的组派接方法第七实施例的流程示意图，该实施例为第二通信终端85挂断与目标组之间的组呼，包括以下步骤：
步骤111：第二通信设备85分别通过语音调度台83和监听调度台86将第三呼叫挂断消息发送给互联服务器81。
正在进行的组呼在第二通信终端85发起断开请求后，语音调度台83和监听调度台86都会收到第二通信终端85通过系统服务器82发送的第三呼叫挂断消息，并分别将第三该呼叫挂断消息上报给互联服务器81。
步骤112：互联服务器81接收到第三呼叫挂断消息时，发送挂断请求给目标组，挂断第二通信终端85和目标组之间的语音连接。
互联服务器81只处理语音调度台83上报的第三呼叫挂断消息，将接收到的第三呼叫挂断消息转发给目标组，并强拆或者挂断与目标组之间的组呼。
此外，语音调度台83接收到第三呼叫挂断消息之后，负责取消自己当前监听的组，将取消监听消息通过系统服务器82发送给第二通信终端85。
通过利用集群通信系统下的语音调度台83和监听调度台86作为互联互通的资源，利用语音调度台83建立语音链路进行语音的传递，在呼叫结束后释放该语音链路，实现语音调度台83的重复利用，能够实现组呼的挂断。
