图 1表示本发明实施例所述的 TD集群 UE群组实现方法的流程示意图。 参见图 1所示,所述集群 UE的无线资源控制 RRC层包括空闲模式和连接 模式; 其中, 在所述 RRC层为连接模式时, 所述集群 UE实现群组方法包括: S 102: 控制所述集群 UE进入说状态, 使得所述集群 UE获取一群组的话权, 并独占所述群组通信的上行专用信道; 在所述 RRC层为空闲模式时, 所述 集群 UE实现群组方法包括: S101 : 控制所述集群 UE进入听状态, 使得所述 集群 UE在所述群组中处于接收状态,并与所述群组内的全部听状态 UE共享 所述群组通信的下行业务信道。
在本实施例的上述技术方案中, 对集群 UE的 RRC状态, 在与 UTRAN 无连接时, 分为 IDLE态, T— DSCH态, 在 IDLE态, 新增功能为 BCCH上接 收集群 T— FACH资源, 接收 T—FACH信道上的组呼业务配置信息并进行相关 配置; 在 T— DSCH态, 该状态为集群中特有状态, 特指在群组业务中只有下 行业务信道(处于接收状态)、 上行为公共信道(RACH信道) 的 UE状态, 即集群中处于听状态的 UE。 与 UTRAN有连接时, 新增 T— CELL— DCH状态。 T CELL DCH, UE存在上行专用信道, 下行为群组内用户共享信道, 特指 集群中有话权的 UE,即集群中处于说状态的 UE。并且根据上述定义的状态, 集群 UE可以组建一群组或加入一已有群组,如步骤 S 102即为集群 UE组建一 群组从 IDLE态进入 T— CELL— DCH态, 也可以加入集群的一已有群组, 如步 骤 S101即为集群 UE加入一群组从 IDLE态进入 T— DSCH态。 上述对 RRC的状 态重新划分, 以满足实现集群功能的需要。
更具体的说, 上述各状态在集群的群组组建及释放群组的整个过程中 均可以相互转换, 以达到集群 UE可以反复变换,让群组内的用户说话交流, 直到这个群组呼叫结束的目的。
图 2表示本发明实施例所述的 TD集群 UE群组各状态间转换的示意图。 参见图 2所示, 由于 CELL— FACH沿用原 TD***, 并且从, IDLE态迁移 到 CELL— FACH态 A以及从 CELL— FACH态迁移到 IDLE态 B沿用原 TD***, 这里不予说明。 以下针对 TD集群各个状态下的功能, 以及状态之间的转换 故详细说明。
状态一: IDLE态,为实现集群 UE的群组功能, IDLE态新增功能为 BCCH 上集群 T— FACH资源接收, 接收 T— FACH信道上的组呼业务配置信息并进行 相关配置。
状态二: T— DSCH态, 该状态为集群中特有状态, 特指在群组业务中只 有下行业务信道(处于接收状态)、 上行为公共信道(RACH信道)的 UE状 态。 该状态功能如下: 正常接收群组业务信令及数据; 接收服务小区*** 消息, 对变更的广播消息能够及时更新; 监听并接收寻呼消息, 用于发起 混合业务或接入高优先级的业务; 进行自主切换; 话权申请。
状态三: T— CELL— DCH, UE存在上行专用信道, 下行为群组内用户共 享信道。 该状态功能如下: 测量控制; 选择并配置应用于此 RRC状态下所 使用的传输信道的 RB复用选项; 对在 DCCH上所收到的 RRC消息进行处理。
参见图 2, 上述状态一、 状态二、 状态三相互间转换过程如下: 状态迁移 C: IDLE态迁移到 T— CELL— DCH态, 集群 UE发起群组业务呼 叫后进入由 IDLE态转换到 T— CELL— DCH态, 此时上行业务信道为专用, 下 行业务信道为群组内用户共享。
^!犬态迁移 D: T CELL DCH态迁移到 IDLE态, 群组业务中 T— CELL— DCH态的 UE收到业务释放的消息后, 集群 UE从 T— CELL— DCH态 转换到 IDLE态。
状态迁移 E: T— DSCH态迁移到 T— CELL— DCH态, 已经处于群组业务中 的听用户的 UE在得到话权后由 T— DSCH态转换到 T— CELL— DCH态。
状态迁移 F: T— CELL— DCH态迁移到 T— DSCH态, 已经处于群组业务中 说用户的 UE在得到话权释放消息或发起话权释放请求后由 T— CELL— DCH 态跳转到 T— DSCH态。
状态迁移 G: IDLE态迁移到 T— DSCH态, 处于 IDLE态下的 UE在收到群 组业务的寻呼消息并且正确接收到业务资源配置消息后, 进入 T— DSCH态, 该状态为 UE自主转换, 不需要网络侧指定。
状态迁移 H: T— DSCH态迁移到 IDLE态, 已经处于群组业务中的听用户 的 UE在收到群组业务释放消息后, 由 T— DSCH态进入 IDLE态。
上述实施例通过演示集群 UE各状态间转换的流程说明通过对 RRC状态 的重新划分, 在原有 TD***的基础上可以完成集群 UE的群组功能, 实现群 组内的用户说话交流。
图 3表示本发明实施例所述的集群 UE从接入群组到群组释放的流程图。 参见图 3所示, 在本实施例中, 一集群 UE读取完集群相关 SI后, 会驻留 到集群小区, 并进入 IDLE态。 该 TD集群 UE群组实现方法具体可包括: 步骤一: 集群 UE所在群组存在, 则读取该群组的物理资源, 并接入到 该群组, 使该 UE从 IDLE态迁移到 T— DSCH态。
步骤二: 话权申请过程, 集群 UE通过向网络申请话权, 当网络为该 UE 分配话权后, 则该 UE从 T— DSCH态迁移到 T— CELL— DCH态。
步骤三: 组释放过程, 更高优先级的集群 UE向网络发起释放请求, 当 网络释放所属群组后, 则该 UE从 T— CELL— DCH态迁移到 IDLE态。
上述实施例为一典型的接入群组到群组释放的过程, 即集群 UE的群组 已经存在, 对于任一想加入该群组的集群 UE可通过上述过程实现从空闲态 进入听状态, 再从听状态进入说状态, 当然用户还可以根据具体的通话交 流需要进行个状态间的相互转换, 达到群组交流的目的。
图 4表示本发明实施例所述的集群 UE从群组组建到群组释放的流程图。 参见图 4所示, 在本实施例中, 同样是一集群 UE读取完集群相关 SI后, 会驻留到集群小区, 并进入 IDLE态。 该 TD集群 UE群组实现方法具体可包 括:
步骤(一): 组呼建立过程, 集群 UE向网络申请组建群组, 网络为该群 组建立无线链路等资源后, 则该 UE从 IDLE态迁移到 T— CELL— DCH态。
步骤(二): 话权释放过程, 当集群 UE向网络发起释放话权后, 网络释 放该 UE的话权, 使得该 UE从 T— CELL— DCH态迁移到 T— DSCH态。
步骤(三): 组释放过程, 集群 UE向网络发起释放请求, 当网络释放所 属群组后, 则该 UE从 T— DSCH态迁移到 IDLE态。
上述实施例为集群通讯***中通过 TD集群中状态的迁移来说明典型的 群组建立到群组释放过程。 即集群 UE的组建一群组并实现从空闲态进入说 状态, 再从说状态返回至空闲态, 当然用户还可以根据具体的通话交流需 要进行个状态间的相互转换, 达到群组交流的目的。
图 5表示本发明实施例所述的 TD集群 UE群组实现装置的结构示意图。 参见图 5所示, TD集群 UE群组实现装置包括: 第一控制模块 50, 用于 控制所述集群 UE进入说状态, 使得所述集群 UE获取一群组的话权, 并独占 所述群组通信的上行专用信道; 第二控制模块 52, 用于控制所述集群 UE进 入听状态, 使得所述集群 UE在所述群组中处于接收状态, 并与所述群组内 的全部听状态 UE共享所述群组通信的下行业务信道。
优选地, 所述第一控制模块 50包括: 第一发起模块(图中未示), 用于 所述集群 UE向网络侧发起一群组呼叫业务, 并在所述网络侧成功建立所述 群组后, 控制所述集群 UE由空闲状态转入所述说状态。
优选地, 集群 UE群组实现装置还包括: 转入模块(图中未示), 用于所 述集群 UE的上级集群 UE向所述网络侧发起释放所述群组的请求,并在所述 网络侧成功释放所述群组后,所述集群 UE从所述说状态转入所述空闲状态。
优选地, 集群 UE群组实现装置还包括: 接入模块(图中未示), 用于所 述集群 UE读取一已有群组的物理资源后接入所述已有群组, 并控制所述集 群 UE由所述空闲状态转入所述听状态。
优选地, 所述第二控制模块 52包括: 第二发起模块(图中未示), 用于 已经处于所述群组的所述集群 UE向网络侧发起申请话权请求, 并在所述网 络侧成功分配所述话权后,控制所述集群 UE由所述听状态转入所述说状态。
优选地,所述集群 UE群组实现装置还包括:第三发起模块(图中未示), 用于所述集群 UE向所述网络侧发起释放话权的请求, 并在所述网络侧成功 释放话权后, 控制所述集群 UE从所述说状态转入到所述听状态。
优选地,所述集群 UE群组实现装置还包括:第四发起模块(图中未示), 所述集群 UE向所述网络侧发起释放所述群组的请求, 并在所述网络侧成功 释放所述群组之后, 所述集群 UE从所述听状态转入所述空闲状态。 集群 UE 包括上述的集群 UE群组实现装置。
通过本发明的上述实施例, 可以看出, 为了满足 TD集群功能的需要, 以原 TD***为基础, 依据集群 UE端新增的功能, 对集群 UE端 RRC层的功 能, 以及状态重新划分并对各个状态下所需实现的功能进行重新定义, 以 满足集群功能需要。 以上所述是本发明的优选实施方式, 应当指出, 对于本技术领域的普 通技术人员来说, 在不脱离本发明所述原理的前提下, 还可以作出若干改 进和润饰, 这些改进和润饰也应视为本发明的保护范围。 工业实用性
本发明实施例以原 TD***为基础, 依据集群 UE端新增的功能, 对集群
UE端 RRC层的功能, 以及状态重新划分, 具体划分方式为: 与 UTRAN无连 接时, 分为空闲 IDLE态, T— DSCH态, 也称听状态, 其中 IDLE态沿用原 TD*** IDLE模式功能, 并加入了 TD集群相关功能; 与 UTRAN有连接时, 分为 CELL— FACH态, T— CELL— DCH态, 也称说状态, 并对各个状态下所需 实现的功能进行重新定义, 采用本发明实施例能满足集群功能需要。
