判断用户设备之间的距离是否超过了直接 D2D通信的范围； 判断用户设备的签约数据是否允许进行 D2D通信； 在用户设备之 间的距离超过了直接 D2D通信的范围， 通过中间节点进行 D2D通信时， 判断所述中 间节点是否具备中继通信能力。 在用户设备之间采用 D2D进行集群通信时， 可以向演进型基站 eNB发送指示信 息， 其中， 该指示信息用于指示在用户设备之间采用 D2D进行集群通信， eNB为用户 设备之间采用 D2D进行集群通信分配资源，在用户设备之间基于分配的资源采用 D2D 进行集群通信。 另外， 还可以向演进型基站 eNB发送话权占用提示信息， 其中， 话权 占用提示信息用于指示话权授权，在用户设备之间基于话权授权采用 D2D进行集群通 信。 其中， 可以通过以下方式至少之一确定话权授权： 话权申请、 话权抢占； 根据话 权授权向 eNB发送话权占用提示信息。

通信处理装置二的结构框图， 如图 11所示， 该装置包括第一发送模块 112、 第二接收 模块 114和第二通信模块 116， 下面对该装置进行说明。 第一发送模块 112， 设置为发送集群通信请求； 第二接收模块 114， 连接至上述第 一发送模块 112， 设置为接收指示信息， 其中， 该指示信息设置为指示采用 D2D进行 集群通信， 以及采用 D2D进行集群通信的资源； 第二通信模块

通信是指邻近的设备间直接通信， 如蓝牙， 由于缺少网络管控， D2D通信一般采用非授权频谱， 如 2.4GHz。 随着智能手 机的快速普及， 出现了很多新的应用， 如基于位置应用， 社交应用等等。 在移动通信 网络中， 用户设备之间的通信必须通过网络进行， 图 14是相关技术中 D2D通信示意 图， 如图 14所示， 即使两个设备位于邻近的位置， 这是因为网络运营商需要对授权频 谱进行管控， 当通信双方使用授权频谱进行通信时， 必须通过网络， 以实现网络对通 信活动的资源调度， 计费和管理等。 为了降低网络负载， 有些公司提出了邻近设备直 接通信的设想， D2D通信具备广播通信和中继通信功能， 因此在集群通信中采用 D2D 技术具有天然的优势， 特别是在以下场景： 用户在网络覆盖区外或盲区工作； 用户在 没有部署基站的地区工作； 网络侧设备出现故障时。基于 D2D通信的上述优势， 在本 实施例中将 D2D通信应用于集群通信，但是，采用 D2D实现集群通信应该由谁决定？ 网络如何配置采用 D2D的集群通信？采用 D2D的集群通信的业务流程如何处理？等 等， 在相关技术中均还没有相应的解决方案。 基于上述问题，在本实施例中提供了一种利用设备到设备 D2D技术实现集群通信 的方法， 该方法包括： 具有 D2D能力的集群用户设备 UE向移动管理实体 MME发起 集群通信请求， MME选择通过 D2D实现集群通信； MME向 UE所在基站 eNB发送 采用 D2D的集群通信指示， eNB为 UE分配 D2D用户面无线通信资源， UEs采用 D2D 进行集群通信。 通过上述实施例及优选实施方式， 能够实现采用 D2D实现集群通信， 通过上述设置， 可以降低网络负载， 减少集群通信对网络的依赖。 下面结合优选实施方式进行说明。 图 15是根据本发明优选实施例的利用 D2D实现集群通信的系统架构图， 如图 15 所示， 组通信实体 （Group Communication Entity, 简称为 GCE) 为有线调度台和无线 网络之间的网关， 还负责该集群系统与其他集群系统的互联互通。 图 16是根据本发明优选实施例的实现集群通信的方法流程图， 如图 16所示， 该 流程包括如下步骤： 步骤 S1602, 用户设备 UE向 MME发送集群通信请求。 其中， 用户设备 UE具备集群通信功能， 如专用集群通信终端， 或增加了集群通 信模块的通用终端； 上述终端包括用户终端和调度台， 用户终端包括手持终端、 车载 台和固定台等； 调度台包括有线调度台和无线调度台。 用户终端和无线调度台通过空 中接口与长期演进 （Long Term Evolution, 简称为 LTE) 网络相连， 有线调度台通过 集群网关与网络子系统相连。 用户设备出于空闲态时， 需要先发起无线资源控制 RRC连接建立过程； 用户设备 UE通过所在基站 eNB向 MME发送集群通信请求消息； MME通过归属用户服务器 HSS归属用户服务器 （Home Subscriber Server, 简称为 HSS) 对 UE进行鉴权并判断 其是否有权限发起集群业务， 如果鉴权不通过， 则 MME拒绝 UE的业务请求； 用户 设备可以是有线调度台， 有线调度台通过 GCE向 MME发送请求消息。 步骤 S 1604， MME判断是否可以采用 D2D进行集群通信，如果是，转向步骤 S 1606， 否则转向步骤 S1610。 该 MME根据用户设备间的距离， 用户设备能力， 和用户设备签约数据等判断是 否可以进行 D2D通信； 如果用户设备间距离满足 D2D通信要求， UE具有 D2D通信 能力且签约数据允许 D2D，则可以进行 D2D通信，否则不能进行 D2D通信；上述 D2D 通信能力保存在用户设备的签约数据或 USIM卡中。 需要指出的是： 用户设备间距离超过了直接 D2D通信的范围， MME可以选择通 过中间节点进行 D2D通信。 该中间节点是指： 用户设备， 或 eNB。 参与 D2D通信的用户设备位于相同的 eNB范围内， 则可以通过中间的其他用户 设备或 eNB中继进行 D2D通信；如果 D2D通信的用户设备不能通过 eNB或其他中间 节点通信， 则采用通过网络通信。 该中间节点要求具有中继通信的能力， 该 MME通过签约数据确定中间节点是否 具有中继通信能力。 步骤 S1606， MME向 eNB指示采用 D2D进行集群通信。
MME通过 S1-MME接口向所述 eNB发送消息： 指示采用 D2D进行集群通信。 eNB为参与集群通信的用户设备所在的 eNB， 可以为一个或多个 eNB， 一个或多 个 eNB与相同的 MME进行通信。 步骤 S1608， eNB分配集群通信的用户面无线资源， UE采用 D2D通信。 该 eNB配置集群通信的用户面无线资源， 当集群通信结束， 用户设备或 MME请 求释放集群通信资源；上述 D2D通信的无线资源采用授权频谱，即运营商使用的频谱。 集群通信中， 用户面通信通过 eNB分配的资源直接在空口进行， 即不再通过核心 网； 控制面通信通过网络完成， 以实现网络对集群通信的管控。 步骤 S 1610， MME选择通过网络进行集群通信。
MME 请求建立通过网络的集群通信用户面路径和资源， 用户设备通过网络进行 集群通信。 下面通过具体集群业务流程的实施例来说明本发明的方案； 为了便于说明， 以下 实施例包含以下假设： 参与集群通信的 UE位于相同的 eNB覆盖范围内； 参与集群通 信的 UE具备 D2D通信能力。需要指出的是:如果参与集群通信的 UE位于不同的 eNB 覆盖范围内， 同样可以采用本发明的方法， 其中的 D2D通过 eNB或 UE中继实现。 实施例一 图 17是根据本发明实施例的针对组呼建立流程的场景，实现设备通信方法的流程 图， 如图 17所示， 该流程包括如下步骤： 步骤 S1700， UE1与基站 eNB之间建立 RRC连接； 步骤 S1702， UE1通过 eNB向 MME发送集群呼叫建立请求消息。 如果发起组呼业务时， UE1处于空闲状态， 则当主叫用户输入组号码， 按下即按 即说（Push To Talk,简称为 PTT)键时， UE1需要先发起无线资源控制（Radio Resource Control, 简称为 RRC) 连接建立过程；
UE1通过非接入层 （Non-Access Stratum, 简称为 NAS) 信令发送集群呼叫建立 请求消息， 其中业务类型为组呼。 步骤 S 1704， MME对 UE1进行鉴权。 该 MME通过 HSS查询 UE1的签约数据并判断 UE1是否有权限发起组呼业务， 如果鉴权不通过 （如 HSS没有返回 UE1签约数据， 或签约数据显示 UE1不能发起组 呼）， 则 MME拒绝 UE1的业务请求。 步骤 S1706， MME向 eNB发送集群无线接入承载建立请求。 MME根据参与组呼的 UE的位置和签约信息确定可以采用 D2D进行集群通信； 该请求消息中包含 D2D通信指示； 如果 UE1从空闲态发起组呼请求， 则 MME发送初始上下文建立请求， 如果 UE1 为连接态， 则 MME发送集群无线接入承载建立请求。 步骤 S1708， eNB向 UE1发送 RRC连接重配置消息。
RRC连接重配置消息修改 RRC连接， 用于传输无线资源配置信息。 eNB通过 RRC连接重配置消息对 UE1的上行资源进行配置。 步骤 S1710， UE1向 eNB发送 RRC连接重配置完成消息。 步骤 S1712， eNB向 MME发送集群无线接入承载建立响应。 eNB向 MME指示 UE1的上行无线资源配置完成。 需要指出的是： 这里的上行无 线资源是指 D2D的通信资源， 根据运营商策略， 可采用 LTE空口的上行或下行资源。 上述步骤 S1706-步骤 S1712为主叫 UE1的上行资源建立过程。 步骤 S1714， MME向 eNB发送集群上下文建立请求消息。 集群上下文建立请求用于建立被叫 UE的上下文。 步骤 S1716， eNB广播集群寻呼消息。 集群寻呼消息用于寻呼组中被叫 UE.所述寻呼消息可以通过专用的集群寻呼逻辑 信道发送。 步骤 S 1718， UE响应寻呼消息。
UE为组中的被叫， UE根据寻呼消息中的组标识判断是否为自身所在的组， 如果 是， 则响应寻呼消息； 否则， 则忽略寻呼消息。 步骤 S 1720， eNB广播集群呼叫建立请求消息。 集群呼叫建立请求用于建立组呼中被叫方 UE的下行空口资源。 步骤 S 1722， UE响应请求消息。
UE为请求组的被叫方。 步骤 S1724， eNB向 MME发送集群上下文建立响应消息。 eNB为被叫 UE分配下行集群空口资源， 即 D2D通信资源， 并通知 MME资源配 置完成。 步骤 S1714-步骤 S1724 为被叫 UE 的下行资源建立过程。 需要指出的是： 步骤 S1706-步骤 S1712和步骤 S1714-步骤 S1724可以并行进行。 步骤 S1726， MME通过 eNB向 UE1发送集群呼叫接受消息。 呼叫接受消息用于话权授权， 即 UE1拥有话权。 步骤 S1728， MME向 eNB发送话权占用提示消息。 步骤 S1730， eNB广播话权占用提示消息。 eNB通知组中 UE/用户话权占用提示。 步骤 S 1732， 集群通信通过 D2D进行。 集群通信中的主、 被叫通过已分配的空口上下行资源进行 D2D通信。 网络侧对 D2D集群通信进行监控， 以保证通信质量， 同时对通信计费。 实施例二 图 18是根据本发明实施例的针对组呼释放集群通信场景，实现设备通信方法的流 程图， 如图 18所示， 其中 UE1代表组呼发起者， UE2为当前占有话权的用户设备， 包括： 步骤 S1802， UE1通过 eNB向 MME发送集群呼叫释放请求。 请求通过 NAS信令发送； 请求的业务类型为组呼， 包含组标识。 步骤 S1804， MME对请求者 UE1鉴权。 MME通过 HSS获取 UE1的签约数据， 核查 UE1是否有权发起组呼释放过程， 如果鉴权不通过则拒绝 UE1的请求， 否则执行步骤 S1806。 步骤 S1806， MME向 eNB发送集群上下文释放请求， 集群上下文释放请求用于释放该组呼的上下文。 步骤 S1808， eNB释放 UE2的无线通信资源。 eNB释放 UE2的 D2D空口资源， 包括上行和下行资源。 步骤 S1810， eNB向 UE2发送 RRC连接重配置消息。 步骤 S1812， UE2向 eNB发送 RRC连接重配置完成响应。 以上步骤 S1808-步骤 S1812用于释放占有话权的 UE2的上下行无线资源。 步骤 S1814， eNB释放 UE1的无线资源。 用于释放 UE1的下行 D2D共享无线资源。 步骤 S 1808-步骤 S1812和步骤 S1814可以同时进行。 步骤 S 1816， eNB广播发送集群呼叫释放消息。 集群呼叫释放消息用于向组中 UE/用户指示组呼停止。 步骤 S1818， eNB向 MME发送集群上下文释放响应。 步骤 S1820， MME通过 eNB向 UE1发送集群呼叫释放接受消息。
UE1 收到集群呼叫释放接受消息后， 可以释放 RRC连接返回空闲态， 或者保持 RRC连接到定时器超时。 实施例三 图 19是根据本发明实施例的针对话权申请集群通信的场景，实现设备通信方法的 流程图， 如图 19所示， 其中用户设备 UE1、 UE2所在群组正在进行组呼， 当前无人 讲话， 话权空闲。 UE1发起话权申请。 包括： 步骤 S1902， UE1通过 eNB向 MME发送集群话权请求消息。 如果申请话权时， UE1处于空闲状态， 则当用户按下 PTT键时， UE1需要先发起 RRC连接建立过程。 步骤 S1904, 核查 UE1签约数据。
MME通过 HSS核查 UE1签约数据是否有话权， 如果是， 则继续步骤 S1902,， 否则， MME拒绝 UE1请求。 步骤 S1906， MME向 eNB发送集群上下文修改请求消息。 MME执行话权策略控制， 如果 UE1 申请话权时处于空闲状态， 则 MME向 eNB 发送初始上下文建立请求消息； 如果 UE1申请话权时处于连接状态， 则 MME向 eNB 发送集群上下文修改请求。
MME根据参与组呼的 UE的位置和签约信息确定采用 D2D进行集群通信； 请求 消息中包含 D2D通信指示。 步骤 S1908， eNB为 UE1配置上行无线资源。 无线资源为 D2D通信的空口资源， 根据运营商策略， 可采用 LTE空口的上行或 下行资源。 步骤 S 1910， eNB向 UE1发送 RRC连接重配置消息。 步骤 S1912， UE1向 eNB发送 RRC连接重配置完成响应。 步骤 S1914， eNB向 MME发送集群上下文修改请求响应。 响应指示 UE1的上行资源配置完成。 步骤 S1916， MME通过 eNB向 UE1发送集群话权响应。 响应为话权授权指示。 步骤 S 1918， MME向 eNB发送话权占用指示消息。 步骤 S1920， eNB广播发送话权占用指示消息。 eNB通知组中的用户/ UE话权已占用。 实施例四 图 20是根据本发明实施例的针对话权抢占集群通信的场景，实现设备通信方法的 流程图， 如图 20所示， 用户设备 UE1、 UE2所在群组正在进行组呼， UE2占有话权。 UE1的用户优先级高于 UE2。 包括： 步骤 S2002， UE1通过 eNB向 MME发送集群话权请求消息。 如果申请话权时， UE1处于空闲状态， 则当用户按下 PTT键时， UE1需要先发起 RRC连接建立过程。 步骤 S2004， MME向 HSS核查 UE签署数据。
MME通过 HSS中的签约数据判断 UE1与当前占有话权的 UE2的优先级高低， 并根据话权策略决定话权授予； 如果 UE1优先级低于 UE2， 则 MME拒绝 UE1的请 求。 步骤 S2006， MME向 eNB发送集群上下文修改请求消息。
MME根据参与组呼的 UE的位置和签约信息确定采用 D2D进行集群通信； 请求 消息中包含 D2D通信指示。 步骤 S2008， eNB释放 UE2的上行无线资源。 无线资源为 D2D或网络通信中的上行资源。 步骤 S2010， eNB向 UE2发送 RRC连接重配置消息。 步骤 S2012， UE2向 eNB发送 RRC连接重配置完成响应。 步骤 S2014， eNB向 MME发送集群上下文修改请求响应。 步骤 S2016， eNB为 UE1分配上行无线资源。 上行无线资源为 D2D通信的上行空口资源， 根据运营商策略， 可采用 LTE空口 的上行或下行资源。 步骤 S2018， eNB向 UE1发送 RRC连接重配置消息。 步骤 S2020， UE1向 eNB发送 RRC连接重配置完成响应。 步骤 S2022， eNB向 MME发送集群上下文修改请求响应。 步骤 S2024， MME通过 eNB向 UE1发送集群话权响应。 响应为话权授权指示。 步骤 S2026， MME向 eNB发送话权占用指示消息。 步骤 S2028， eNB广播发送话权占用指示消息。 基于上述指示消息类型的方法， 在本实施例中还提供了一种集群通信的系统， 图 21是根据本发明实施例的集群通信系统的示意图， 如图 21所示， 该系统包括： MME 212、 用户设备 214、 基站 eNB 216， 下面对该系统进行说明。
