本发明涉及通信领域，尤其涉及一种集群通信中集群终端迟后进入组呼/广播呼叫方法。The invention relates to the field of communication, in particular to a method for a group terminal to enter a group call/broadcast call late in the group communication.
背景技术Background technique
集群通信系统诞生于70年代末到80年代初。其工作方式类似电话交换系统，通过中央交换站根据需要自动为用户指定信道。集群通信的基本原理是：由中央控制器集中控制和管理系统中的每个信道，并以动态方式迅速把空闲信道分配给发起呼叫的用户，通话完成后又将该信道收回给等待的用户使用，因此，极大地提高了频道使用率。The trunking communication system was born in the late 1970s to the early 1980s. Its working method is similar to the telephone switching system, and the channel is automatically assigned to the user through the central switching station as needed. The basic principle of trunking communication is: the central controller centrally controls and manages each channel in the system, and dynamically allocates the idle channel to the user who initiates the call quickly, and returns the channel to the waiting user after the call is completed. , thus greatly increasing channel usage.
集群通信系统通常包括诸如组呼、广播呼叫、紧急呼叫、发起或接收与公网之间的呼叫等多种呼叫功能；同时，可以为用户提供可靠的通信信道、快速建立通话、优先等级划分、动态重组能力等功能，尤其是在执行紧急任务时，这些功能更显重要。使用者可根据不同部门的需要共同使用一套集群通信系统，为如政务、公用设施管理、环境卫生、警务、消防等建立通话系统，而每个部门可以依其任务的需要，建立起符合自身任务要求的特定通话组群，而且集群通信系统具有弹性的扩充能力，因此能够随着业务需求的增加，扩充系统容量及调整系统组态，并且能够持续以软件方式升级。The trunking communication system usually includes multiple call functions such as group call, broadcast call, emergency call, initiating or receiving calls with the public network, etc.; at the same time, it can provide users with reliable communication channels, fast call establishment, priority division, Features such as dynamic reconfiguration capabilities, especially when performing emergency missions, are even more important. Users can use a set of trunking communication system together according to the needs of different departments to establish a communication system for government affairs, public facilities management, environmental sanitation, police, fire protection, etc., and each department can establish a communication system that meets the needs of its tasks. The specific call group required by its own tasks, and the trunking communication system has flexible expansion capabilities, so it can expand the system capacity and adjust the system configuration with the increase of business needs, and can continue to upgrade through software.
在集群组呼/广播呼叫通信中，集群终端作为被呼叫对象，需要能够正常参加每一次集群组呼/广播呼叫通信，但在现有的情况中，常常会出现集群终端因为自身或者网络的原因而无法正常参加组呼/广播呼叫通信的情况，比如集群组呼/广播呼叫通信时，某一个集群终端恰巧处于断电状态或者网络无法覆盖的区域，这样该集群终端就无法正常参与本次组呼/广播呼叫通信。按照现有的技术方案，该种情况无法解决。而如果集群终端漏掉了某次组呼/广播呼叫，则有可能产生很严重的后果，这与集群通信的安全性和快捷性是相背离的。In the trunking group call/broadcast call communication, the trunking terminal, as the called object, needs to be able to normally participate in each trunking group call/broadcast call communication, but in the existing situation, it often happens that the trunking terminal is Due to some reasons, the group call/broadcast call communication cannot be normally participated in. For example, during the trunking group call/broadcast call communication, a certain trunking terminal happens to be in a power-off state or an area that cannot be covered by the network, so the trunking terminal cannot participate normally. This group call/broadcast call communication. According to the existing technical solutions, this situation cannot be solved. However, if the trunking terminal misses a certain group call/broadcast call, serious consequences may occur, which is contrary to the security and quickness of the trunking communication.
发明内容Contents of the invention

If there is, the call notification information will be displayed on the terminal and added to the The cluster group call/broadcast call.
所述步骤C中，所述未加入本次呼叫的集群终端，可以是下述之一：In the step C, the cluster terminal that has not joined this call can be one of the following:
呼叫发起时处于关闭状态，在呼叫建立后开机的终端；A terminal that is turned off when the call is initiated and turned on after the call is established;
呼叫发起时与网络失去联系，在呼叫建立后与网络恢复联系的终端；A terminal that loses contact with the network when the call is initiated, and recovers contact with the network after the call is established;
呼叫发起时处于呼叫受理范围之外，在呼叫建立后回到呼叫调度区域内的终端；The terminal is outside the call acceptance range when the call is initiated, and returns to the terminal in the call dispatching area after the call is established;
呼叫发起时处于不可被终止的业务过程中，在呼叫建立后原业务过程结束的终端。A terminal that is in a service process that cannot be terminated when the call is initiated, and the original service process ends after the call is established.
所述的步骤B中，所述的呼叫通知是周期发送的。In the step B, the call notification is sent periodically.
所述的步骤C中，未加入本次呼叫的终端监听公共信道或其占用信道上的呼叫通知。In the step C, the terminal not participating in the current call monitors the call notification on the public channel or the channel it occupies.
所述的步骤C中，如果所述的未加入本次呼叫的集群终端当前有非本次呼叫的业务正在接入，则停止当前正在接入的业务，并响应本次呼叫通知，加入本次呼叫。In the step C, if the cluster terminal that has not joined this call is currently accessing services other than this call, then stop the currently accessing service, respond to the call notification, and join this call call.
所述的集群终端监听是否有针对其呼叫通知，是通过在该终端上显示所述的呼叫通知信息来完成的。The cluster terminal monitors whether there is a call notification for it, which is accomplished by displaying the call notification information on the terminal.

具体实施方式Detailed ways
下面结合说明书附图来说明本发明的具体事实方式。The specific fact mode of the present invention will be described below in conjunction with the accompanying drawings.
迟后进入对于集群系统是非常重要的特性，保证集群用户的服务质量。迟后进入是指，对于某个组呼/广播呼叫建立时没有立即加入的用户终端，系统可以在本次组呼/广播呼叫进行过程中将其加入的一项集群补充业务。这里的组呼/广播呼叫，可以是集群组呼、广播呼叫等。Late entry is a very important feature for cluster systems to ensure the quality of service for cluster users. Late entry refers to a trunking supplementary service that the system can add to a user terminal that does not join immediately when a group call/broadcast call is established. The group call/broadcast call here may be a trunking group call, a broadcast call, and the like.
迟后进入的终端可以是以下几种：The late entry terminals can be the following types:
a 组呼/广播呼叫发起时处于关闭状态，在组呼/广播呼叫建立后开机的终端；a A terminal that is turned off when the group call/broadcast call is initiated and turned on after the group call/broadcast call is established;
b 组呼/广播呼叫发起时由于处于网络覆盖不到的区域等原因而与网络失去联系，在组呼/广播呼叫建立后与网络恢复联系的终端；b A terminal that loses contact with the network due to reasons such as being in an area not covered by the network when the group call/broadcast call is initiated, and restores contact with the network after the group call/broadcast call is established;
c 组呼/广播呼叫发起时由于处于系统定义的组呼/广播呼叫受理范围(简称组呼/广播呼叫的调度区域)之外，在组呼/广播呼叫建立后回到组呼/广播呼叫的调度区域内的终端；c When the group call/broadcast call is initiated, because it is outside the acceptance range of the group call/broadcast call defined by the system (referred to as the scheduling area of the group call/broadcast call), it returns to the group call/broadcast call after the group call/broadcast call is established. Terminals in the dispatch area;
d 组呼/广播呼叫发起时正处于其他不可被该组呼/广播呼叫自动强行终止的业务过程中，在组呼/广播呼叫建立后原进行的业务过程结束的终端。d. When the group call/broadcast call is initiated, it is in the process of other business processes that cannot be automatically and forcibly terminated by the group call/broadcast call, and the terminal whose original business process ends after the group call/broadcast call is established.
如图1所示，是本发明实施例的一个系统结构示意图，本实施例以基于GSM的集群调度系统为例进行说明，但本发明的适用范围并不局限于此，本发明适用于TETRA、IDEN以及其它制式的数字集群通信系统。从图1中可见，该集群网络结构，包括基站、基站控制器、移动交换机和调度控制系统，终端要求能够支持集群调度业务。其中调度控制系统是一个逻辑实体，主要负责调度业务的处理，可以是独立设置，也可以与其他实体(如移动交换机、基站控制器)在物理上进行合设。As shown in Figure 1, it is a schematic diagram of a system structure of an embodiment of the present invention. This embodiment is described by taking a GSM-based cluster scheduling system as an example, but the scope of application of the present invention is not limited thereto. The present invention is applicable to TETRA, IDEN and other standard digital trunking communication systems. It can be seen from Figure 1 that the cluster network structure includes base stations, base station controllers, mobile switches and dispatch control systems, and terminals are required to support cluster dispatch services. Among them, the dispatch control system is a logical entity, which is mainly responsible for the processing of dispatch services. It can be set up independently, or it can be set up physically together with other entities (such as mobile switches and base station controllers).
如图2所示，是本发明的集群终端迟后进入组呼/广播呼叫的流程示意图，从图中可见，主要包括以下步骤：As shown in Figure 2, it is a schematic flow chart of the trunking terminal of the present invention entering a group call/broadcast call later, as can be seen from the figure, it mainly includes the following steps:
S1、集群通信系统侧向组呼/广播呼叫设定的集群终端发送组呼/广播呼叫通知，建立组呼/广播呼叫通信。S1. The trunking communication system sends a group call/broadcast call notification to the trunking terminal configured for group call/broadcast call, and establishes group call/broadcast call communication.
当某一个集群系统欲发起组呼/广播呼叫时，系统侧向组呼/广播呼叫设定的集群终端发送组呼/广播呼叫通知，触发建立组呼/广播呼叫通信。这时，所有设定的集群终端，在网络及集群终端功能正常的时候，接收所述的呼叫通知，并做出响应，加入到本次组呼/广播呼叫通信中。When a trunking system intends to initiate a group call/broadcast call, the system side sends a group call/broadcast call notification to the trunking terminal set for the group call/broadcast call, triggering the establishment of group call/broadcast call communication. At this time, all the set trunking terminals receive the call notification when the network and the trunking terminals are functioning normally, and make a response to join this group call/broadcast call communication.
S2、集群通信系统侧重复向组呼/广播呼叫设定的集群终端发送呼叫通知。S2. The trunking communication system side repeatedly sends a call notification to the trunking terminal configured for the group call/broadcast call.
为了避免本次组呼/广播呼叫的集群用户因为各种原因而没有接入到本次组呼/广播呼叫，集群通信系统侧重复向本次组呼/广播呼叫设定的集群用户发送呼叫通知，该呼叫通知与本次组呼/广播呼叫建立时所发送的呼叫通知相同。In order to prevent the cluster users of this group call/broadcast call from not accessing this group call/broadcast call due to various reasons, the trunking communication system side repeatedly sends call notifications to the cluster users set for this group call/broadcast call , the call notification is the same as the call notification sent when this group call/broadcast call is established.
该重复发送呼叫通知的步骤，可以周期地进行，这样可以保证在本次组呼/广播呼叫通信过程中，可以多次提醒未加入本次业务的集群终端，以减少系统漏呼的可能性。The step of repeatedly sending the call notification can be performed periodically, so as to ensure that during the communication process of the group call/broadcast call, the trunking terminals that have not joined the service can be reminded multiple times, so as to reduce the possibility of system missed calls.
本步骤中，发送呼叫通知时，发送途径包括在系统的公共信令信道上发送，以及集群用户占用的业务信道上发送。In this step, when sending the call notification, the sending method includes sending on the public signaling channel of the system and sending on the traffic channel occupied by the trunking user.
当关机的用户终端开机、本次组呼/广播呼叫建立时不再服务区/调度区的用户终端进入服务区/调度区、本次组呼/广播呼叫建立时正在进行高优先级业务的用户终端空闲时，其具备了接入到本次组呼/广播呼叫的条件，便可加入到本次组呼/广播呼叫了。这时候，进入到步骤S3中。When the user terminal that is powered off is turned on, the user terminal that is no longer in the service area/dispatching area enters the service area/dispatching area when this group call/broadcast call is established, and the user that is performing high-priority services when this group call/broadcast call is established When the terminal is idle, it meets the conditions for accessing the group call/broadcast call, and can join the group call/broadcast call. At this time, go to step S3.
S3、设定的集群终端中，未加入本次组呼/广播呼叫的集群终端监听其所在群组的呼叫通知。S3. Among the set trunking terminals, the trunking terminals that have not joined the current group call/broadcast call monitor the call notification of the group they belong to.
设定的集群终端中，未加入本次组呼/广播呼叫的集群终端监听其所在群组的呼叫通知，以随时获取是否有被漏呼的信息。Among the set trunking terminals, the trunking terminals that have not joined the current group call/broadcast call monitor the call notification of the group they belong to, so as to obtain information on whether there is a missed call at any time.
本步骤中，集群终端在空闲状态下，要监听公共信令信道上的呼叫通知，在参与呼叫的状态，要检测当前正在接入的业务信道上的呼叫通知。In this step, in the idle state, the trunking terminal needs to monitor the call notification on the public signaling channel, and in the state of participating in the call, it needs to detect the call notification on the service channel currently being accessed.
S4、未加入本次组呼/广播呼叫的集群终端，加入本次组呼/广播呼叫。S4. The trunking terminals that have not joined the current group call/broadcast call join the current group call/broadcast call.
本次组呼/广播呼叫设定的集群用户中，如果得知有被漏呼的信息存在，则加入本次组呼/广播呼叫。Among the cluster users set for this group call/broadcast call, if they know that there is information about missed calls, they will join this group call/broadcast call.
本步骤中，当接收到呼叫通知后集群终端能够显示相应的组呼信息，并能够提示集群用户是否加入。而对于退出的组呼/广播呼叫，当接收到对应该群组的呼叫通知时，终端可以不再提示。In this step, after receiving the call notification, the trunking terminal can display corresponding group call information, and can prompt the trunking user whether to join. As for the withdrawn group call/broadcast call, when receiving the call notification corresponding to the group, the terminal may no longer prompt.
本次组呼/广播呼叫设定的集群用户中，如果有被漏呼的现象存在，则接受所述的呼叫通知，加入本次组呼/广播呼叫。If there is a missed call among the cluster users set for this group call/broadcast call, then accept the call notification and join this group call/broadcast call.
如图3所示，是本发明的一个实施例的流程示意图，图3中的呼叫通知1、呼叫通知2分别代表发送不同基站的呼叫通知。这里只画出了两个基站，每个基站一个信道的情况，实际应用中需要向更多数量的基站，以及单个基站下多个业务信道发送呼叫通知。As shown in FIG. 3 , it is a schematic flowchart of an embodiment of the present invention. Call notification 1 and call notification 2 in FIG. 3 respectively represent call notifications sent by different base stations. Only two base stations are shown here, and each base station has one channel. In practical applications, it is necessary to send call notifications to more base stations and multiple service channels under a single base station.
当集群用户收到呼叫通知后，根据呼叫通知的信息接入到相应的组呼/广播呼叫信道，参加组呼/广播呼叫。这个接入过程不同的无线通信系统存在差异，由相应的无线通信系统定义。After receiving the call notification, the trunking user will access the corresponding group call/broadcast call channel according to the call notification information, and participate in the group call/broadcast call. This access process is different for different wireless communication systems, and is defined by the corresponding wireless communication system.
本发明保证各种情况下的终端能够及时参加正在进行的呼叫，提高对集群用户的服务质量，保证了集群组呼/广播呼叫的安全性和准确性。The invention ensures that terminals in various situations can participate in ongoing calls in time, improves service quality for trunking users, and ensures security and accuracy of trunking group calls/broadcast calls.
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
