以下结合附图对本发明的实施例进行详细说明， 但是本发明可以由权利 要求限定和覆盖的多种不同方式实施。
在介绍本发明具体的技术方案之前， 需要了解集群 UE 中处于听状态的 用户如何获取邻区资源信息， 以下两实施给出了在空闲状态下进入听状态以 及从说状态进入听状态的用户如何获取邻区资源信息。
图 1表示本发明空闲态下集群 UE收到组呼寻呼进入听状态的流程图。 参见图 1所示， 空闲态下集群 UE收到组呼寻呼进入听状态具体可包括 以下步骤：
步骤 201 :—个集群 UE在空闲 Idle态下，收到一个集群组呼的寻呼消息； 步骤 202: UE会读取当前的系统信息块 SIB, 此集群系统的 SIB中包含 有集群专有 FACH ( Forward Access channel, 向前接入信道 )信道所需要的资 源信息， UE根据此资源信息配置集群专有 FACH信道；
步骤 203: 同时， 网络侧建立起一个组呼后， 会在集群专有 FACH信道 上下发配置 UE到听状态的当前组呼本小区及邻区的资源信息；
步骤 204: UE根据本小区的资源信息配置 UE到听状态， 同时存储此组 呼的邻区资源信息到本地的存储模块；
步骤 205: 集群 UE进入听状态。 在上述过程中， 网络侧建立起一个组呼后， 会在集群专有 FACH信道上 下发配置 UE到听状态的当前组呼本小区及邻区的资源信息 UE根据本小区的 资源信息配置 UE到听状态， 同时存储此组呼的邻区资源信息到本地， 因此， 在之后集群 UE需要进行小区切换时， 可以到本地获取邻区资源信息以实现 小区的切换。
图 2表示本发明说状态的集群 UE转入听状态的流程图。
参见图 2所示， 一个说状态的集群 UE转入听状态的步骤为：
步骤 301 : 网络侧释放话权；
步骤 302: 当网络侧释放话权后， UE配置听状态；
步骤 303: UE需要读取 SIB, 根据 SIB中集群专有 FACH信道配置资源 配置 FACH信道；
步骤 304: 网络侧根据群专有 FACH信道下发组呼本小区及邻区信道资 源信息；
步骤 305: 根据组呼本小区资源信息配置 UE到听状态，存储邻区物理信 道资源信息；
步骤 306: 集群 UE进入到听状态。
综上可知， 邻区资源信息的获取方式包括如下：
1. 当 UE从空闲态转到听状态的时候。 UE根据 SIB中的配置专有 FACH 信道， 在集群专有 FACH信道上读到当前组呼的本小区和邻区的信道资源信 息后， 配置当前组呼的资源信息， 进入听状态， 并且存储邻区的信道资源信 息供后续在新小区切换的时候配置资源。
2. 当 UE从说状态转入听状态的时候， UE在首次进入说状态或者从听 状态转入说状态后续在说状态过程中发生了小区切换， UE 都没有从专有 FACH信道获取邻区物理信道资源， 所以从说状态转入听状态的时候也需要 配置集群专有 FACH信道， 读取邻区的信道资源信息， 供后续在新小区切换 的时候配置资源。
3.当听用户成功切换到新小区后， 由于小区变化， 新小区的邻区关系和 原小区不同， 也需要重新获取邻区的物理信道资源信息。 听用户 UE重新获 取新小区的 SIB信息，根据 SIB信息读取集群专有 FACH信道，配置专有 FACH 信道， 获取新小区的邻区物理信道资源信息， 供后续在新小区切换的时候配 置资源。
图 3表示本发明实施例所述的集群 UE切换方法的流程图。
参见图 3所示， 集群 UE切换方法可包括如下步骤：
S101 : 测量当前小区的信号质量与邻区的信号质量；
S103: 判断所述当前小区的信号质量与所述邻区的信号质量是否均满足 预设的判决规则， 并得一判断结果；
S105: 在所述判断结果为所述当前小区的信号质量与所述邻区的信号质 量均满足所述预设的判决规则时， 集群用户设备 UE从所述当前小区切换至 所述邻区。
本实施例的上述技术方案是集群 UE在小区中移动时发现更好的邻区后， 将当前所在的小区切换至邻区的技术方案， 所谓的更好的邻区， 即指信号质 量更高的小区， 但是， 是否切换仍然需要遵循一判决规则， 该判决规则预设 设定并保存在协议帧内，例如临区的信号比本小区的信号质量大于一个门限， 就触发测量报告给网络， 决定网络控制切换到临区。
图 4表示本发明实施例所述的说状态的集群 UE发生切换的流程图。 参见图 4所示， 在本实施例中， 设定当前小区为小区 1 , 需要切换至的 邻区为小区 2。 UE目前处于小区 1 , 说状态， 因此， 说状态的集群 UE实现 切换的具体步骤可以包括：
步骤 401 : 该 UE为说用户， 说用户根据网络侧的测量指令， 测量小区 1 及小区 2的信号质量， 当 UE发现了更好的邻区后， 即发现小区 2的信号质 量比小区 1的信号质量更好， UE会触发邻区的测量报告；
步骤 402: 网络侧收到测量报告后，会通过物理信道重配消息给 UE下发 小区 2的资源信息；
步骤 403: UE收到后会根据网络下发的小区 2的资源信息配置小区 2的 资源；
步骤 404: 配置成功后， 向网络侧发送物理信道重配完成消息； 步骤 405： UE在小区 2中进入说状态。
上述技术方案针对的是集群 UE中处于说状态的 UE的小区切换，该过程 可以使集群 UE 中的说用户在小区中移动的时候可以发生切换而不中断当前 的业务， 实现集群 UE的移动性管理。
图 5表示本发明实施例所述的听状态的集群 UE发生切换的流程图。 参见图 5所示， 同样本实施例中， 设定当前小区为小区 1 , 需要切换至 的邻区为小区 2。 并且集群业务中上行信道是说用户独享的， 听用户的集群 UE在进行业务的时候， 上行信道是不可以用的。 听用户不能和说用户一样， 当发现更好的邻区的时候， 通过测量 4艮告通知网络邻区的测量信息， 网络侧 根据邻区测量信息判决 UE切换到合适的小区。 当发现了更好邻区的时候， 听用户 UE根据集群专有 FACH中接收到的邻区资源信息， 配置底层资源， 该邻区资源信息在图 1与图 2的实施例中已经明确示出存储在本地， 即通过 听用户在空闲状态及从说用户转入听用户时从集群专有 FACH中获取并存储 在本地的存储模块中。
更具体地， 听状态的集群 UE发生切换的步骤可以包括：
步骤 501 : UE目前处于小区 1 , 听状态， 即小区 1中的一个听状态的集群 UE, 通过读取系统信息中的邻区信息， 发现了更好的小区 2的时候， UE会根 据之前存储的小区 2的物理信道资源信息， 配置 UE到小区 2的听状态。
步骤 502: 在小区 2中， UE需要读取 SIB信息， 根据 SIB中集群专有 FACH 信道配置资源配置 FACH信道；
步骤 503: 集群专有 FACH信道下发组呼小区 1及小区 2信道资源信息； 步骤 504: 根据组呼本小区资源信息配置 UE到听状态， 存储邻区物理信 道资源信息；
步骤 505: UE在小区 2进入听状态。
综上可知， 对于听用户的切换流程： 1. 从 SIB中获取 TFACH信道（新 定义的信道， 区别于 TD中的 FACH信道） 资源信息； 2.配置 TFACH信道。
3.从 TFACH信道获取当前听用户的资源配置（ PHY,MAC,RLC等 )及邻区资 源配置信息。 4.测量发现更好小区满足切换门限， 直接跟踪之前在 TFACH信 道接收到的临区资源配置信息配置直接切换到目标的小区 （邻区， 相当于在 切换之前已经获取到临区的资源配置信息 ) 。

网络侧设备包括上述的集群 UE切换装置。
综上， 对于说状态的集群 UE, 因为上行信道资源说用户共享， 说状态的 集群 UE可以上报邻区的测量报告，网络可以根据说状态的集群 UE上报的测 量报告及网络的当前状态来决定配置 UE到目标小区， 成功实现说状态 UE 的切换过程。 对于听用户： 1. 从 Idle态进入到说状态的 UE, 读取了邻区的 物理信道资源信息后并存储， 后续发生切换可以根据存储的邻区物理信道资 源信息切换到目标小区。 2.对于从说状态转入到听状态的听状态集群 UE, 在 状态发生转换的时候也读取并存储了邻区的资源信息， 后续发生切换也可以 根据存储的邻区资源信息成功切换到目标小区。 3. 对于之前就是听用户的用 户， 发生切换后， UE也读取了新小区的邻区物理信道资源， 后续如果再发生 切换， 也可以根据存储的资源信息成功切换到目标小区。
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
