Description

组呼建立方法及其系统 技术领域  Group call establishment method and system thereof
本发明涉及集群通信技术领域, 尤其涉及一种组呼建立方法及其系统。 背景技术  The present invention relates to the field of trunking communication technologies, and in particular, to a group call establishing method and system thereof. Background technique
数字集群通信网是二十世纪末兴起的新型移动通信系统, 它除了具备公 共移动通信网 (如 GSM、 CDMA网络等)所能提供的个人移动通信服务外, 还能实现个人与群体间的任意通信。  The digital trunking communication network is a new mobile communication system that emerged at the end of the 20th century. In addition to the personal mobile communication services that public mobile communication networks (such as GSM and CDMA networks) can provide, it can also realize any communication between individuals and groups. .
其中, GT800 集群通信技术是一种基于时分多址的专业数字集群通信新 技术,它结合蜂窝通信技术,通过对 TDMA和 TD - SCDMA通信技术的优化 与组合,可为专业集群用户提供高性能、大容量的集群通信业务; 并且 GT800 集群通信系统具有系统性能稳定, 可持续发展能力强、 快速的接续性能和高 速率的数据业务等优点。  Among them, GT800 trunking communication technology is a new professional digital trunking communication technology based on time division multiple access. It combines cellular communication technology to optimize the combination of TDMA and TD-SCDMA communication technologies to provide high performance for professional cluster users. Large-capacity cluster communication service; and GT800 trunking communication system has the advantages of stable system performance, strong sustainable development capability, fast connection performance and high-speed data service.
目前, 在 GT800集群通信系统中, 网络侧在用户发起组呼业务时, 需要 在所有小区的通知信道(NCH, Notification Channel )上发送组呼通知消息, 该发送的组呼通知消息中包含组呼标识(组呼 ID ); 对应群组中的其他用户通 过监听自身所处小区中的 NCH信道, 一旦发现在 NCH信道上发送的组呼通 知消息中包含的组呼 ID 和自身用户识别模块 ( SIM, Subscriber Identity Module )中预先写入的组呼 ID相同, 就立即响应该组呼通知消息, 加入到上 述用户发起的组呼中, 从而完成该组呼的建立。  Currently, in the GT800 trunking communication system, when the user initiates a group call service, the network side needs to send a group call notification message on the notification channel (NCH, Notification Channel) of all the cells, and the group call notification message includes the group call. Identification (group call ID); other users in the corresponding group monitor the group call ID and the self-user identification module included in the group call notification message sent on the NCH channel by monitoring the NCH channel in the cell in which the cell is located. In the Subscriber Identity Module, the pre-written group call ID is the same, and immediately responds to the group call notification message, and joins the group call initiated by the user, thereby completing the establishment of the group call.
由于目前在 GT800集群通信系统中, NCH信道资源是十分有限的, 一般 情况下一个小区可能就被分配一个 NCH信道。 这样在大量数目的组呼同时发 起后, 网络侧需要在各个 NCH信道上周期的发送各个不同的组呼通知消息, 由于 NCH信道资源比较紧张, 当多个组呼通知消息都需要发送时, 就需要将 各个組呼通知消息在该 NCH信道上进行排队发送, 因此当网络侧要发送的组 呼通知消息数目过多时, 就可能会造成组呼通知消息的发送滞后或丟失, 这 样必将影响到组呼通信业务的运行质量。 发明内容 Since the NCH channel resources are currently very limited in the GT800 trunking communication system, a cell may be allocated an NCH channel in general. After a large number of group calls are simultaneously initiated, the network side needs to periodically send different group call notification messages on each NCH channel. Since the NCH channel resources are relatively tight, when multiple group call notification messages need to be sent, Each group call notification message needs to be queued and sent on the NCH channel. Therefore, when the number of group call notification messages to be sent by the network side is too large, the group call notification message may be delayed or lost. This will definitely affect the operational quality of the group call communication service. Summary of the invention

NCH channel resources in. That is, in the GSM-based trunking communication system, the initiator of the group call adopts the normal group call initiation process (same as the prior art), and the users in other groups join the group call to adopt the paging mode proposed by the solution of the present invention.
下面将结合各个附图对本发明方案的主要实现原理及其具体实施方式进 行详细的阐述。  The main implementation principles of the solution of the present invention and its specific embodiments will be described in detail below with reference to the accompanying drawings.
请参照图 1 , 该图是本发明组呼建立方法的主要实现原理流程图, 其主要 实现过程如下:  Please refer to FIG. 1 , which is a flow chart of the main implementation principle of the group call establishment method of the present invention. The main implementation process is as follows:
步骤 S10, GSM制式的集群通信系统网络侧在用户发起组呼时, 根据该 用户发来的组呼发起消息中承载的组呼标识(组呼 ID ), 索引该用户所在的群 组; 其中组呼的这个发起过程与现有技术的发起过程相同, 本发明这里不再 过多予以赘述;  Step S10: The network side of the trunking communication system of the GSM system indexes the group call identifier (group call ID) carried in the group call initiation message sent by the user when the user initiates the group call, and indexes the group where the user is located; The initiation process of the call is the same as the initiation process of the prior art, and the present invention will not be repeated here;

步骤 S20, GSM制式的集群通信系统网絡侧才艮据索引到的该用户所在的 群组中的其他各用户标识(用户 ID ),依次将该群组中的其他各用户寻呼到该 用户发起的组呼中, 从而完成该组呼的建立, 即网络侧根据组中其他各用户 的标识信息(如号码信息等)通过 PCH信道寻呼各用户, 使各用户接收到寻 呼消息后, 能够加入到该发起的组呼中。  Step S20: The network side of the GSM system of the trunking communication system is based on the index of other user identifiers (user IDs) in the group in which the user is located, and sequentially pages other users in the group to the user. The group calls, thereby completing the establishment of the group call, that is, the network side pages each user through the PCH channel according to the identification information (such as number information, etc.) of other users in the group, so that each user can receive the paging message, Join the group call that was initiated.

Meanwhile, the user identifier (user ID) mentioned in the above step S20 may be but not limited to the user number information.
请参照图 2,该图是本发明方法中网络侧通过寻呼方式将組内其他各用户 呼入到组呼中, 建立组呼的处理流程图, 其具体的实现过程如下:  Please refer to FIG. 2, which is a flowchart of processing a group call by calling the other users in the group to the group call by using the paging mode in the method of the present invention. The specific implementation process is as follows:
步驟 S201 , GSM制式的集群通信系统网络侧才艮据上述索 1到的该用户所 在的群组中的其他各用户号码信息(各用户的 MSISDN信息), 获取对应各用 户的国际移动用户识别码(IMSI );  Step S201: The network side of the GSM system of the GSM system obtains the international mobile subscriber identity corresponding to each user according to the other subscriber number information (the MSISDN information of each subscriber) in the group where the user is located. (IMSI);
步驟 S202, GSM制式的集群通信系统网络侧根据上述获取到的各用户的 IMSI, 依次对该群组中的其他各用户分别发起寻呼; Step S202, the network side of the GSM standard trunking communication system is obtained according to the obtained users. IMSI, in turn, initiates paging for each of the other users in the group;
步骤 S203, 该群组内的其他各用户接收到网络侧发来的寻呼消息后, 分 别向网络侧反馈寻呼响应消息;  Step S203: After receiving the paging message sent by the network side, the other users in the group separately feed back the paging response message to the network side;
步骤 S204, GSM制式的集群通信系统网絡侧针对反馈寻呼响应消息的每 个用户, 判断是否已为反馈寻呼响应消息的该用户分配了组呼信道, 如果是, 执行步骤 S205; 否则执行步骤 S206;  Step S204, the network side of the trunking communication system of the GSM system determines, for each user of the feedback paging response message, whether the group call channel has been allocated for the user who feeds the paging response message, and if yes, step S205 is performed; otherwise, the step is performed. S206;
步骤 S205, GSM制式的集群通信系统网络侧指配该用户到已分配的组呼 信道上;  Step S205, the network side of the GSM standard trunking communication system assigns the user to the allocated group call channel;
步骤 S206, GSM制式的集群通信系统网络侧为该用户分配新的组呼信 道, 并将该用户指配到该新分配的组呼信道上。  Step S206: The network side of the GSM system trunking communication system allocates a new group call channel to the user, and assigns the user to the newly allocated group call channel.
一个 居本发明方案原理实现组呼建立过程的实施例:  An embodiment of the method for establishing a group call in accordance with the principle of the present invention:
GT800 集群通信系统网络侧通过组呼 ID 查询本组呼对应的各用户 MSISDN号, 并分别根据各 MSISDN号码, 获得各用户的 IMSI号码, 然后 根据各用户的 IMSI号码执行寻呼处理流程, 即通过组内各用户的 IMSI号码 依次寻呼组内各用户。 组内各用户收到寻呼消息后, 回应寻呼响应消息, 网 络侧给回应寻呼响应消息的用户分配组呼信道, 并将用户指配到分配的组呼 信道上; 如果此时组呼信道已经建立, 则直接指配用户到已经分配的组呼信 道上。  The network side of the GT800 trunking communication system queries the MSISDN number of each user corresponding to the group call by using the group call ID, and obtains the IMSI number of each user according to each MSISDN number, and then performs a paging processing process according to the IMSI number of each user, that is, The IMSI numbers of each user in the group sequentially page each user in the group. After receiving the paging message, each user in the group responds to the paging response message, and the network side allocates a group call channel to the user responding to the paging response message, and assigns the user to the allocated group call channel; If the channel has been established, the user is directly assigned to the already assigned group call channel.
网络侧根据上行信道占用情况进行接网, 即将发言者的上行信道接续到 组内各接听者的下行信道上  The network side picks up the network according to the occupancy of the uplink channel, and connects the uplink channel of the speaker to the downlink channel of each listener in the group.
组呼建立后, 进入目前正常的组呼上行占用流程, 即用户通过即按即讲 ( PTT, Push To Talk )抢占方式抢占上行信道, 进行发言。  After the group call is established, the current normal group call uplink occupation process is entered, that is, the user preempts the uplink channel by using a PTT (Push To Talk) preemption mode to make a speech.
如果上行信道长时间无人占用, 网络侧将主动拆除该组呼, 并释放各个 用户占用的组呼信道。 其中各个用户可以通过挂机方式退出组呼。  If the uplink channel is unoccupied for a long time, the network side will actively remove the group call and release the group call channel occupied by each user. Each user can quit the group call by hanging up.
在组呼建立成功后, 后续群组内各个用户进行組呼通信过程中, 无论是 发言者用户还是接听者用户都可能发生在不同小区之间进行移动的问题, 这 就涉及到移动性管理的解决方式, 其中本发明方法这里提出在建立成功的组 呼中, 发言用户通过小区切换处理来实现移动性管理(具体实现过程同现有 技术中的小区切换处理:); 而接听用户则通过小区重选处理来实现移动性管 理。 After the group call is successfully established, during the group call communication process of each user in the subsequent group, both the speaker user and the listener user may move between different cells, which involves mobility management. Solution, wherein the method of the present invention is presented herein in establishing a successful group In the call, the speaking user implements mobility management through cell handover processing (the specific implementation process is the same as the cell handover processing in the prior art:); and the receiving user implements mobility management through cell reselection processing.
请参照图 3 ,该图是本发明方法中接听用户通过小区重选处理来实现移动 性管理的处理流程图, 其具体实现过程如下:  Please refer to FIG. 3 , which is a flowchart of processing in which the user in the method of the present invention implements mobility management through cell reselection processing, and the specific implementation process is as follows:
步骤 S301 , 接听用户在组呼通信过程中, 根据各个邻小区的信号情况, 定位一个合适的新小区;  Step S301: The receiving user locates a suitable new cell according to the signal condition of each neighboring cell in the group call communication process;
步骤 S302, 接听用户在该定位的新小区中向网络侧发送重选通知消息; 步驟 S303, 网络侧在接收到重选通知消息后, 判断该新小区中是否存在 已经建立的組呼信道, 如果是, 执行步骤 S304; 否则执行步骤 S305;  Step S302, the receiving user sends a reselection notification message to the network side in the located new cell. Step S303, after receiving the reselection notification message, the network side determines whether there is an established group call channel in the new cell, if If yes, go to step S304; otherwise, go to step S305;
步骤 S304, 网络侧将该接听用户指配到该新小区中的组呼信道上, 然后 转至步骤 S306;  Step S304, the network side assigns the answering user to the group call channel in the new cell, and then proceeds to step S306;
步驟 S305 , 网络侧为该新小区分配新的组呼信道, 并将该接听用户指配 到新分配的組呼信道上;  Step S305: The network side allocates a new group call channel to the new cell, and assigns the answering user to the newly allocated group call channel.
步驟 S306, 网络侧在该接听用户所处的原小区中进行下行检测处理; 步骤 S307, 网络侧根据上述下行检测结果, 判断该原小区中是否还存在 接听用户, 如果是, 执行步驟 S308; 否则执行步據 S309;  Step S306, the network side performs downlink detection processing in the original cell where the user is located. Step S307, the network side determines, according to the downlink detection result, whether there is still an answering user in the original cell, and if yes, step S308; otherwise, Execution step according to S309;
步驟 S308, 网络侧保留该原小区中的组呼信道;  Step S308, the network side reserves the group call channel in the original cell;
步骤 S309, 网络侧删除该原小区中的组呼信道。  Step S309, the network side deletes the group call channel in the original cell.
本发明组呼建立方法在组呼用户规模比较小的情况下, 通过在 PCH信道 发送寻呼消息代替在 NCH信道发送组呼通知消息来实现组呼的建立, 由于寻 呼消息是针对用户所在的位置区进行发送的, 无需全网发送; 这样在用户数 目比较少的情况下, 仅需要部分 PCH信道资源即可以实现组呼的建立; 而同 样对于这种小规模组呼, 采样在 NCH信道上发送组呼通知消息, 则需要在全 网进行发送, 因此会造成 NCH信道资源的严重浪费。  The group call establishment method of the present invention realizes the establishment of the group call by sending a paging message on the PCH channel instead of sending the group call notification message on the NCH channel, in the case that the group call user is relatively small, since the paging message is for the user If the location area is sent, it does not need to be sent over the entire network. In this case, if the number of users is relatively small, only part of the PCH channel resources are needed to establish the group call. For the small-scale group call, the sample is also sampled on the NCH channel. Sending a group call notification message needs to be sent on the entire network, thus causing serious waste of NCH channel resources.
相应的, 本发明还提出了一种组呼建立系统。 请参照图 4, 该图是本发明 组呼建立系统的主要組成结构框图,其中本发明组呼建立系统包括 GSM制式 的集群通信系统网络侧和终端设备,其中 GSM制式的集群通信系统网络侧包 括索引单元 10和寻呼单元 20, 各部分的作用如下: Correspondingly, the present invention also proposes a group call establishment system.
