Description

组呼业务的实现方法及其系统 技术领域
本发明涉及语音通信技术领域， 尤其涉及一种组呼业务的实现方法及其 实现系统。 背景技术
目前语音通信技术的发展， 已经从过去的点对点语音业务逐步发展到点 对多点语音业务， 其中现有的集群通信系统就是点对多点语音通信业务的一 种应用情况。 目前业界通用的集群通信系统主要包括 IDEN， TETRA, GT800 和 GOTA等系统， 而这些通信系统都是专业的集群通信系统， 需要组建专门 的网络， 并需要具有支持集群通信功能的终端进行支持。 通用的集群通信业 务主要是一对多点的半双工组呼语音业务； 通常情况下， 集群通信技术广泛 应用于各种专网通信上, 如交警系统、 铁路系统及其公安系统等多采用集群 通信技术进行集群通信。
但是伴随着语音业务的发展, 越来越多的大众用户也渴望能够享受基本 的组呼业务， 如经常一起打牌的朋友， 或球迷组合， 或车友会及其一些亲属 等， 这些群组用户都希望能够在自己的群组内进行集群组呼通信， 但是这些 群组用户一般只拥有普遍的个人通信终端， 如手机等， 而分别为这些群組用 户专门组建对应的集群通信网络似乎又不太值得。
基于上述原因， 业界提出了在公共通信网络系统上（如 PLMN网络、 或 PSTN网络等， 以下简称"公网，，）实现集群组呼通信的技术，如会议电话技术、 多方通话技术和 POC ( PTT Over Cellular )技术等， 其中：
会议电话技术： 指用户通过申请会议电话功能， 拨打会议组号， 来参加 会议。 会议电话可以有多人参加， 但是由于会议电话通常采用会议桥方式进 行多方话路汇聚， 所以会议桥资源对于会议电话而言就显得非常重要了， 然 而目前 MSC会议桥资源很有限， 不能用于大规模提供会议电话业务。 多方通话技术： 多方通话最多可以支持六方同时通话， 例如由用户 A发 起多方通话呼叫， 用户 A先与用户 B建立通话， 并保持与 B的通话； 再与用 户 C建立通话， 并通过终端菜单操作， 令用户 C加入会话， 此时 A、 B、 C 可同时通话。 依次类推， 用户 A可逐次分别与 D、 E、 F建立通话， 并令其加 入会话。 用户 A可单独与 B、 C、 D、 E、 F中的一个通话， 而保持其他用户 的通话， 也可与 B、 C、 D、 E、 F同时通话。 多方通话需要多个用户的通信终 端分别支持呼叫保持功能。
POC技术： POC通信业务是由公网提供的， 用于在 IP网络上承载的一种 集群通话业务， 其缺点是由于 IP网络使用的是分组域承载， 话音盾量和通话 的实时性不能够得到 4艮好的保证， 仅仅相当于语音短消息， 不能够满足用户 组呼通信的实时性要求。
由此可见， 上述现有技术中提出的在公网上实现组呼业务的各个技术普 遍还存在着会议桥资源占用及其语音通信质量和实时性不能得到很好的保证 的缺陷。 发明内容
本发明要解决的技术问题在于提出一种组呼业务的实现方法及其系统， 以使在公网上实现的组呼通信业务能够保证较好的语音通信质量和实时性要 求。

本发明这里将要提供一种新的在公共通信网上实现组呼通信业务的方法 及其系统， 以在不要求更改用户终端的前提下， 确保较好的语音通信质量和 通信实时性要求。
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。
请参照图 1， 该图是本发明组呼业务的实现方法的主要实现原理流程图， 其主要实现过程如下：
步骤 S10,公共通信网网络侧受理群組用户申请的组呼业务， 并为该群组 分配对应的组呼标识；
其中这里提及的公共通信网可以但不限于为公共陆地移动通信网 ( PLMN ); 也可以为公共电话交换网 （PSTO );
其中一个群组中的任一用户向公网网络侧申请组呼业务的过程如图 2所 示， 其具体的申请过程如下： a. 所述群组内的任一用户在向公网网络侧申请组呼业务时， 将预加入该 群组的各个用户标识通知给公网网络侧；
其中通知的预加入该群组的各个用户标识可以为各个用户的号码信息 (如移动用户的 MSISDN等）；
其中所述群组内的任一用户可以通过短消息方式、 或通过客服电话方式 (如中国移动的 1860客服电话）、 或通过到营业厅直接办理方式实现向公网 网絡侧申请组呼业务， 并将预加入该群组的各个用户标识通知给公网网络侧。
b. 公网网络侧根据申请用户通知的各个用户标识， 分别询问对应的各个 用户是否同意加入该群组； 其中公网网络侧可以通过短消息方式或通过客服 电话方式分别询问对应的各个用户是否同意加入该群组。
c 其他用户接收到公网网絡侧下发的询问信息后，如果同意加入该群组， 就向公网网络侧反馈同意加入信息， 同理各个用户也可以通过短消息方式或 通过客服电话方式将同意加入的信息反馈给公网网络侧。
d.公网网络侧将同意加入该群组的用户加入该群组， 并为该群组分配组 呼标识， 其中公网网络侧为群组分配的组呼标识可以为组呼号码信息， 如可 以使用 "12345"号码信息代表一个群组的组呼标识；
e.公网网络侧将加入群组成功信息及其分配给该群组的组呼标识分别通 知给该群组内的各个用户 （包括申请用户和预加入该群组的各个用户）， 同理 公网网络侧也可以通过短消息方式或通过客服电话方式将加入群组成功信息 及其分配给该群组的组呼标识分别通知给该群组内的各个用户。
一个申请组呼业务的例子：
申请用户通过短信方式、 或者到营业厅直接办理方式、 或者通过 1860业 务平台， 向公网运营商申请组呼业务， 申请时告知公网运营商该群组内成员 的号码信息， 公网运营商才艮据申请， 向群组内每个用户发送询问消息， 如果 该用户同意加入该群組， 就向公网运营商发送同意加入的短信， 或者通过营 业厅方式通知运营商同意加入， 公网网络将该用户成员加入到该群組内， 并 为该群组分配组呼 ID, 然后通过短信或者电话通知、 邮件通知等方式通知该 群组中的每个成员， 网络已经获准其加入该群组及其为该群组分配的组呼 ID 信息， 以通知该群组中的各个成员可以使用该组呼 ID和该群组内的其他用户 实现组呼语音通信。
步骤 S20,公网网络侧将为所述群组分配的组呼标识和所述群组内的各个 用户标识进行绑定； 即在网络侧的相应数据库中针对该群组建立对应的组呼 档案， 该档案中存储有该群组中的各个用户标识信息， 及其网络侧为该群组 分配的组呼标识， 这样网络侧就可以基于群组中的任一用户呼叫的组呼标识， 通过查找该组呼档案， 就可查找到该群组中的任一用户的用户标识信息。
步骤 S30,后续在所述群组内任一用户呼叫所述组呼标识时（即该群组中 的任一用户想发起该组呼通信时， 就可以向公网网絡侧拨叫该组呼标识信息， 如若组呼标识为" 12345"号码信息，则可以通过拨打该组呼号码 "12345"实现向 公网网絡侧发起组呼业务 ), 公网网络侧根据该用户呼叫的组呼标识索引对应 群组内的其他各个用户标识；
步骤 S40,公网网络侧分别根据上述索引到的各个用户标识，将该群组内 的其他各个用户呼入到该组呼中， 其中具体的呼入过程如下：
公网网絡侧根据上述索引到的各个用户标识， 分别呼叫对应的各个用户； 同时将索引到的组呼标识发送到对应的各个用户终端侧进行显示； 这样各个 用户接收到这个组呼呼叫时， 通过识别该组呼标识信息， 来决定是否加入该 组呼， 其中用户准备加入该组呼时， 可以在自身终端设备上按下具体的接听 键， 这样用户的终端设备就可以向公网网絡侧发送摘机接听信号；
针对呼叫的各个用户， 公网网络侧在接收到用户发来的摘机信号后， 就 可以确定已将该用户呼入到该组呼中。
一个呼叫群组中用户接入到组呼的例子：
群组中的任一用户均可通过呼叫组呼 ID 实现向公网网络侧发起組呼业 务， 组呼业务发起时， 公网网络侧通过该组呼 ID查询该群组内各个成员的号 码 , 并根据查询到的各个成员号码通过寻呼将各个組内成员接入组呼。
其中当群组内的任一用户拨打该组呼 ID时， 公网网络侧通过分析该 ID 号码， 得知该呼叫为组呼， 就根据保存的组内用户号码， 如果是移动用户， 获取这些用户的 IMSI和组内用户所在的位置区， 依次对组内用户发起寻呼； 如果是固定用户， 则呼叫该固定号码。
群组内各个用户接收到呼叫消息时， 网络侧振铃提示用户， 群组内用户 根据来电显示号码， 可以判断为某个组呼呼叫， 用户按接听键响应该组呼呼 叫， 网络给每个用户分配一条专用信道。
公网网络侧在经过上述的处理过程， 将一个组呼成功建立后， 网络侧可 以控制该建立起的组呼中各个用户之间采用半双工方式进行点对多点语音通 信。
在群组用户之间基于半双工方式进行语音通信时， 公网网络侧在组呼执 行过程中， 如果接收到该群组内的用户发来的申请发言权信令时， 就将为原 发言用户分配的讲话话路切换给该申请发言权的用户， 同时将原发言用户设 置为接听状态。
其中群组内的用户在组呼过程中， 如果想向公网网络侧申请发言权， 则 可以通过如下过程完成：
网络侧预先规定将用户按下终端上的规定按键 (如" *"键、 或" # "键等） 时， 终端向公网网络侧发送的信号作为申请发言权信令;
后续， 所述群组中的任一用户在组呼过程中， 就可以通过在自身终端上 按下上述规定的 4 建， 实现向公网网络侧申请发言权。
一个用户申请发言权的例子：
在组呼建立成功开始， 公网网络侧将组呼发起者的上行话路搭接到群组 内其他各个听者的下行话路上， 实现一点对多点的语音分发。 这时发起组呼 的用户占用讲话话路， 其他用户处于收听状态。 后续如果其他用户需要讲话， 就通过按键（如 *、 #或者数字键等）发起话路申请， 公网网络侧收到该申请 发言权的信令后， 将讲者话路分配给按键申请发言权的用户， 并将该讲者上 行话路交换到其他听者的下行话路上， 即公网网络侧在听者信道上收到申请 发言权的信令后， 认为该听者需要讲话， 则将该听者的上行话路交换到其他 听者的下行话路上， 该讲者的话音就可以通过网络侧的语音分发， 发送到组 内其他用户的下行话路上， 组内其他用户均可以听见该用户的讲话。 同理， 后续如果又有用户需要讲话， 则可以通过上述相同的办法申请发言权， 依此 类推， 直到所有用户退出组呼或者该组呼皮取消。
后续， 公网网络侧在组呼执行过程中， 如果接收到群组中的用户发来的 退出组呼信令时， 就立即在参加该组呼的群组用户中删除该用户。 其中群组 中的用户可以通过按下自身终端设备上的挂机按键实现向公网网络侧发送退 出组呼信令。 待公网网络侧确认群组中的各个用户全部退出了该组呼通信后， 就立即取消该组呼。
同时按照本发明方案实现原理 , 由于群组中的每个用户被分配一条话路， 用户和网络侧保持专用连接， 所以不会影响用户的移动切换处理。
对于群组中的用户处于网外时， 本网交换机可以^^据组呼建立后組内用 户的号码分析， 依次进行寻呼或者转发到其他网络进行接续， 从而实现对处 于不同公网中的各个组内用户进行接续处理。
一个根据本发明方案原理实现的组呼实施例：
假设用户 A, B, C和 D为经常一起论坛的车友组, 为了便于联系， 该车 友组申请了组呼业务； 其申请过程可以为：
A用户通过短信方式向公网运营商申请了一个组呼 ID, 该申请短信中包 括 A,B,C,D四人的手机号码；
公网网络侧接收到该申请短信后 , 分别发送询问短信给 B，C,D三人， 询 问其是否愿意加入用户 A发起的这个群组；
用户 B,C,D回复确认消息， 表示愿意加入该群组。 公网网络侧将 A， B, C D四人编为一个群组，并为该群组分配专用的组呼 ID,假设组呼 ID为 12345 (有别于普通的用户号码）， 经过上述处理后， 组呼申请登记成功， 这 4个人 可以将该群组称为车友组。
后续， 如果用户 A想邀请其他 3个车友 B、 C、 D进行论坛， 则可以拨打 组呼 ID"12345，，到公网网络侧， 以发起组呼（其拨叫过程和普通拨号一样）； 公网网络侧接收到 12345组呼申请后，根据组呼 ID"12345，，到数据库查找 12345群組的组内成员号码信息， 并分别提取该组内各个成员的 IMSI号码， 依次进行寻呼， 寻呼成功后， 网络为每个被叫用户分配专用的业务信道， 并 将用户 A的上行话音信道交换到用户 B，C,D的下行语音信道上。
用户 B,C,D收到寻呼信息时， 手机振铃提示， 来电号码显示为 12345， 表 明是车友组发起的组呼呼叫， 用户 B，C，D接听电话， 可以收到 A的话音。
如果用户 A说完了， B想发言， 则可以通过按" #，，键， 发送了申请发言 权信令到公网网络侧， 公网网络侧经分析是用户 B发送的申请发言权信令， 则将 B的上行话音信道交换到 A, C, D的下行话音信道上。 A,C,D即可以听 到 B的话音， 其他用户需要讲话， 同理进行上述处理。
后续如果用户 C想退出该組呼， 则可以通过直接按挂机键， 公网网络侧 接收到终端通过按下挂机键发送的退出组呼信令后 ,立即拆除用户 C的话路， 但不影响用户 A， B， D之间的通话。
直到所有用户均退出该组呼， 则网络侧取消该组呼。
综上可见， 上述全部实现过程无须用户更改终端设备， 即目前所有的手 机和固定终端均可支持本发明提出的方案， 并不会影响到用户的移动性， 提 升了用户的 ARPU值。
