Description

宽带集群通信系统及其资源释放、 建立方法、 终端及基站
技术领域
本发明涉及集群通信技术领域， 尤其涉及的是一种宽带集群通信系统的 资源释放、 建立方法、 宽带集群通信系统中的终端、 基站及宽带集群通信系 统。
背景技术
如图 1所示， 长期演进（ Long Term Evolution , 简称 LTE )技术的宽带 集群通信系统， 是在 LTE系统上结合专用集群系统进行扩展实现集群功能的 系统， 主要由集群调度服务器（PTT Dispatching Server, 简称 PDS )、 集成集 群功能的演进的通用陆基无线接入网 （E-UTRAN )基站（E-UTRAN节点或 演进的节点 B, 简称 eNB ) 、 集群终端 （ User Equipment, 简称 UE )等设备 组成， 实现一对多的半双工宽带集群通信。 UE前向监听并接收共享信道发送 的信令和业务数据实现相关业务，反向发送随机接入信令； eNB前向接收 PDS 信令和业务数据进行处理并转发给 UE,反向接收 UE信令进行处理或转发给 PDS; PDS 是信令和业务的集中点， 对话权用户的业务数据接收并转发给所 有非话权用户所在 eNB, 对话权用户和非话权用户的业务信令集中处理。
基于长期演进技术的宽带集群通信系统， 群组非话权用户分布在多个小 区， 在每个小区建立一套下行共享信道资源， 所有该小区组内非话权用户监 听该信道， 实现信令、 语音、 和视频等多媒体宽带业务的接收， 该下行共享 信道资源在群组呼叫建立或非话权用户寻呼响应接入未建资源小区时为群组 非话权用户建立， 在群组释放时发起释放。
相关的宽带集群通信系统， 若非话权用户所在小区下的所有用户已退出 组呼或移到其他小区， 也即， 原小区下当前已经没有用户， 但是该小区下的 资源却要等到组呼释放时才能释放掉， 因此存在小区资源浪费的情况； 另一 方面， 若当前小区的非话权用户检测到其他未建立群组资源的小区更适合自 己而希望发起切换， 但因为目标小区没有建立该群组集群资源而无法进行切 换， 从而导致掉话。
因此， 相关的宽带集群通信系统， 存在群组资源无法动态建立和释放的 缺陷。 发明内容

所述非话权用户归属的基站如判断目标小区不是本基站下的小区， 则判 断所述目标小区是否满足切换条件， 如果是， 则向集群调度服务器 PDS发送 资源建立请求， 其中携带目标小区所属基站的标识和目标小区的标识；
所述 PDS接收到所述非话权用户归属的基站发送的资源建立请求后， 通 知目标小区所属基站为所述目标小区建立所述组呼的群组资源， 其中携带资 源建立指示信息；
目标小区所属基站接收到 PDS的通知后， 根据资源建立指示信息为所述 目标小区建立所述组呼的群组资源， 建立成功后， 向所述 PDS发送目标小区 的群组资源配置信息； 所述 PDS接收到目标小区的群组资源配置信息后将所述群组资源配置信 息转发给所述非话权用户归属的基站， 再由所述非话权用户归属的基站将所 述群组资源配置信息转发给所述非话权用户； 以及
所述非话权用户归属的基站如判断目标小区不是本基站下的小区， 则判 断所述目标小区是否满足切换条件， 如果是， 则向目标小区所属基站发送资 源建立请求， 其中携带目标小区所属基站的标识和目标小区的标识；
所述目标小区所属基站收到所述资源建立请求后， 判断本基站是否在除 所述目标小区之外的其他小区下为所述组呼建立过群组资源， 如已建立过， 则直接为所述目标小区建立所述组呼的群组资源； 如未建立过， 则向 PDS转 发所述资源建立请求； 所述 PDS接收到所述目标小区所属基站发送的资源建 立请求后， 向目标小区归属的基站发送资源建立响应， 其中携带资源建立指 示信息； 所述目标小区归属的基站接收到所述 PDS的资源建立响应后， 根据 资源建立指示信息在所述目标小区下建立所述组呼的群组资源； 目标小区下 的群组资源建立成功后， 将所述目标小区的群组资源的配置信息发送给所述 非话权用户归属的基站， 再由非话权用户归属的基站将所述目标小区的群组 资源的配置信息转发给非话权用户。
24、 如权利要求 21所述的系统， 其中：
所述切换条件包括：所述目标小区为所述非话权用户所在小区的邻小区 , 且所述目标小区支持集群功能。
25、 如权利要求 21-24中任一项所述的基站， 其中：
所述宽带集群通信系统为基于长期演进 LTE技术的宽带集群通信系统。
