发明人在实施本发明的过程中发现：目前的智能手机通常既支持 WiFi 或蓝牙 （BlueTooth ) 等短距离通信技术， 又支持长期演进 (Long Term Evolution , 简称 LTE)、 通用移动通信系统 （ Universal Mobile
Telecommunications System, 简称 UMTS ) 、 CDMA, GSM或 WiMAX等 蜂窝通信技术。 在单网络节点且多用户设备之间的协作通信的场景下， 或 者称为多用户协作通信 ( multiple UEs cooperative communication, 简称 MUCC ) 的场景下， 至少有两个 UE同时支持 WiFi和 LTE时， 为这些同 时支持 WiFi和 LTE的 UE之间建立一种 MUCC的关系 ,可增加可靠性和 吞吐率。 即在其中一个 UE需要发送或接收数据时， 除该 UE之外的其他 UE均可进行支撑， 协助该 UE与基站进行通信。 将被支持的 UE称为受益 UE、 被服务 UE、 被协助 UE或目标 UE, 将除该被协助 UE之外的其他 UE称为支撑 UE、 服务 UE、 协助 UE或中继 UE。
以支撑 UE与受益 UE为例， 受益 UE和支撑 UE的概念是从受益 UE 的承载角度来看的， 例如， UE1和 UE2组成 MUCC, 它们可以相互协助 通信， 从 UE1的某个承载角度来说， UE2可以支撑 UE1的该承载， 因此 UE1是受益 UE, UE2是支撑 UE。 而与此同时， UE1也可以支撑 UE2的 某个承载， 从 UE2的这个承载角度来说， UE2是受益 UE, 而 UE1是支撑 UE。 以支撑 UE与受益 UE为例， 受益 UE为上行数据包的源发送方或者 下行数据的最终接收方。 针对某一承载来说， 一般有一个受益 UE, 而支 撑 UE是用来协助受益 UE而进行数据中转的 UE。 针对受益 UE的某一承 载来说， 可以有多个支撑 UE。 基于以上基本思想本发明实施例将蜂窝网络中的用户设备组成多个 用户设备组， 一个用户设备组内的用户设备之间通过本地网络通信， 基站 与目标用户设备通信时， 目标用户设备所属用户设备组内的中继 UE协助 目标 UE进行通信。 以下实施例中， 基站可以是 2G网络中的基站 （base Transceiver station, 简称 BTS )、相应地，基站控制器可以是 Base station Controller ( BSC ) 。 基站也可以是 3G网络中的 NodeB, 相应地， 基站控 制器可以是无线网络控制器 （ Radio Network Controller, 简称 RNC ) 。 基 站也可以是 LTE网络中的演进基站 （ eNodeB ) 。 .
图 1A为本发明实施例提供的一种数据传输方法流程图。 本实施例主 要说明网络侧设备如何通过用户设备组内的中继用户设备向位于该组内 的目标用户设备发送下行数据包。 如图 1A所示， 本实施例提供的方法包 括：
步骤 11 : 网络侧设备向目标 UE发送下行数据包时， 根据 UE分组信 息确定目标 UE所属 UE组 , 并确定所述目标 UE所属 UE组的中继 UE, UE组内各 UE之间通过本地网络通信。
如图 1B所示， 本发明实施例将蜂窝网络中多个 UE通过本地网络组 成一个 UE组， 一个蜂窝网络中可能会建立多个 UE组。 一个 UE组内各 UE可以通过本地网络路由设备进行通信， 本地网络路由设备可以是 UE 组内具有路由功能的 UE。 一个 UE组内的各 UE之间通过本地网络通信， 例如， 通过 WiFi或者 BlueTooth等短距离无线通讯技术组成的网络通信。 一个 UE组的不同 UE可以归属同一个基站， 也可以归属不同的基站。 UE 组可以通过 UE之间的相互协商建立， 例如 UE通过蓝牙协商建立； 也可 以通过网络侧设备辅助建立， 例如通过 WiFi服务器建立。 一个 UE组的 UE之间通过短距离无线通讯技术建立连接， 因此。 一个 UE组内的 UE之 间的通信可靠性较高。
UE分组信息包括 UE与 UE所属 UE组的组标识的对应关系。 在 UE 组建立成功后， 网络侧设备通过用户设备发送的本地组消息确定用户设备 与所述用户设备所属用户设备组的组标识的对应关系， 建立所述用户设备 分组信息， 所述本地组消息至少包括所述用户设备所属用户设备组的组标 识。 网络侧设备向目标 UE发送下行数据时， 在 UE分组信息中查找目标 UE在所属 UE组的组标识， 通过组标识确定目标 UE所属的 UE组。 网络 侧设备确定目标 UE所属的 UE组后， 在该 UE组内选择任意一个除目 UE 之外的 UE作为中继 UE , 也可以所属 UE组内信号质量最好的 UE为中继 UE。
可选地， 本地组消息还可包括用户设备的宏网络标识。 网络侧设备通 过用户设备发送的本地组消息确定用户设备的宏网络标识与所述用户设 备所属用户设备组的组标识的对应关系。 UE分组信息包括 UE的宏网络 标识与 UE所属 UE组的组标识的对应关系。
步骤 12: 网络侧设备通过所述目标 UE所属 UE组内的中继 UE, 将 下行数据包发送给所述目标 UE, 所述下行数据包中包括所述目标 UE的 宏网络标识 , 所述中继 UE为目标 UE所属 UE组内的 UE。
网络侧设备在目标 UE的下行数据包中添加目标 UE的宏网络标识后， 发送给目标 UE所属 UE组的中继 UE。 目标 UE在中继 UE的协助下 , 获 取网络侧设备发送的下行数据包。 其中， 目标 UE的宏网络标识为 UE在 所属蜂窝网络的网络标识， 或者为目标 UE在所属蜂窝网络的逻辑信道标 识， 或者为 UE在所属蜂窝网络的网络标识和在所属蜂窝网络的逻辑信道 标识的组合。 举例来说， UE所属蜂窝网络为 3G网络， 则 UE在所属蜂窝 网络的网络标识为 UE在 3G网络的网络标识 , 例如高速共享信道无线网 络临时标识 （H-RNTI ) , UE所属蜂窝网络为 2G网络， 则 UE在所属蜂 窝网络的网络标识为 UE在 2G网络的网络标识。
需要说明的是， 本实施例的执行主体网络侧设备可以是基站， 也可以 是基站控制器。 本实施例可以由基站确定目标 UE所属的 UE组和该 UE 组的中继 UE, 也可以由目标 UE归属的基站确定目标 UE所属的 UE组和 该 UE组的中继 UE。
如果由基站确定目标 UE所属的 UE组和该 UE组的中继 UE,步骤 11 可包括： 基站根据基站控制器发送的 UE分组信息， 确定目标 UE所属 UE 组， 确定所述目标 UE所属 UE组内的中继用户设备， 并在所述下行数据 包的介质访问控制 （ Medium Access Control , 简称 MAC ) 层添加目标 UE 的宏网络标识。 基站确定目标 UE所属 UE组内的中继 UE后， 将下行数 据包发送给目标 UE所属 UE组内的中继 UE。 其中， 基站从基站控制器处 获取本地的 UE分组信息。
如果由基站控制器确定目标 UE所属的 UE组和该 UE组的中继 UE, 步骤 11可包括： 基站控制器根据所述 UE分组信息确定目标 UE所属 UE 组的中继 UE , 在下行数据包的无线链路控制 （ Radio Link Control , 简称 RLC ) 层添加所述目标 UE的宏网络标识。 基站控制器确定目标 UE所属 UE组内的中继 UE, 通过与中继 UE之间的通道将下行数据包发送给目标 UE所属 UE组内的中继 UE。
本实施例提供的技术方案中， 网络侧设备通过目标 UE所属 UE组的 中继 UE向目标 UE发送下行数据包， 使得目标 UE在本地网络中的中继 UE的协助下， 接收网络侧设备发送的下行数据包。 由于本实施例为目标 UE接收网络侧设备发送的下行数据包提供了的新途径， 因而提高了目标 UE的吞吐率和通信速率。
可选地， 当 UE处于相同的短距离连接范围内， 网络侧设备可以将下 行数据包分别发送给目标 UE和中继 UE。由目标 UE对从网络侧设备直接 接收到的下行数据包和从中继 UE接收到的下行数据包进行合并。 同理， 行数据的合并， 完成与 UE之间的协作通信。
可选地， 为提高网络侧设备与目标 UE之间的通信可靠性。 步骤 11 中网络侧设备确定中继 UE可以是所属 UE组内信号质量最好的 UE。网络 侧设备通过信号质量最好的 UE向目标 UE发送下行数据包。 网络侧设备 可釆用多种方法确定一个 UE组内信号质量最好的 UE。 可选地， 基站可 根据 UE分组信息和每个 UE周期性上报的信号质量测量指示或事件性上 报的信号质量测量指示， 确定每个 UE组内信号质量最好的中继 UE。 基 站可以向基站控制器上报每个 UE组中信号质量最好的 UE。 可选地， 基 站控制器也可以定期统计用户设备的通信速率， 根据通信速率的大小确定 哪个 UE的信号质量最好。
基站确定每个 UE组内信号质量最好的中继 UE的方法具体如下： 基 站周期性接收每个 UE上报的信号质量测量指示， 或者， 事件性接收每个 UE上报的信号质量测量指示， 即 UE在预设事件的触发下向基站上报信 号质量测量指示。 基站通过信号质量测量指示可确定 UE的信号质量。 另 夕卜， 基站可以通过 UE上报信号质量测量指示的信道或者 UE与基站之间 的连接， 确定 UE在所属蜂窝网络的网络标识， 例如， 无线网络临时标识。 基站确定上报信号质量测量指示的 UE的宏网络标识后， 结合 UE分组信 息确定 UE所属 UE组。 之后， 根据每个 UE组内各 UE的信号质量， 确定 每个 UE组内信号质量最好的中继 UE。
由于中继 UE是本组内信号质量最好的 UE, 因此，基站向目标 UE所 属 UE组内的中继 UE发送下行数据包的成功概率远高于基站向目标 UE 发送下行数据包的成功概率。 并且， 一个 UE组内 UE通过本地网络通信， 组内 UE之间的通信可靠性较高， 中继 UE向本组内的目标 UE发送下行 数据包的成功概率远高于基站向目标 UE直接发送下行数据包的成功概 率。 因此， 在目标 UE所属 UE组内信号质量最好的中继 UE的协助下， 可提高网络侧设备和目标 UE之间的通信可靠性和目标 UE的吞吐率。
可选地， UE向网络侧设备发送上行数据包时， 也可通过本组内的中 继 UE向网络侧设备转发。 进一步， UE可通过组内成员之间的交互获取 到本组内信号质量最好的 UE。 UE可以直接将上行数据包发送本组内的中 继 UE , 也可以先发给本组内的本地网络路由设备， 由本地网络路由设备 将上行数据包转发给本组内的中继 UE。
图 2为本发明实施例提供的另一种数据传输方法流程图。 本实施例主 要说明： 中继 UE接收到基站发送的下行数据包后， 如何转发给目标 UE。 如图 2所示， 本实施例提供的方法包括：
步骤 21 : 中继 UE接收基站发送的下行数据包， 中继 UE为所属 UE 组内的 UE , 下行数据包中包括目标 UE的宏网络标识， 目标 UE的宏网络 标识为 UE在所属蜂窝网络的网络标识， 或者为目标 UE在所属蜂窝网络 的逻辑信道标识， 或者为 UE在所属蜂窝网络的网络标识和逻辑信道标识 的组合； UE组内各 UE之间通过本地网络通信。
步骤 22: 中继 UE根据目标 UE的宏网络标识， 确定自己不是接收下 行数据包的目标 UE时， 根据目标 UE的宏网络标识在所属 UE组内转发 下行数据包。
中继 UE接收基站发送的下行数据包， 确定其中的宏网络标识是否是 自己的宏网络标识。 确定自己不是接收下行数据包的目标 UE后中继 UE 有两种处理方法， 一种是对下行数据包解析后直接发送给目标 UE, 另一 种方法是中继 UE对下行数据包解析后发送给本组的本地网络路由设备， 由本地网络路由设备将下行数据包转发给目标 UE。
可选地， 中继 UE根据所述目标用户设备所属用户设备组的网络标识 映射信息和所述目标用户设备的宏网络标识， 确定所述目标用户设备在所 属用户设备组内的本地网络标识， 所述用户设备组的网络标识映射信息包 括所述用户设备组内每个用户设备的宏网络标识与本地网络标识的对应 关系。 根据所述目标用户设备的本地网络标识， 将所述下行数据包发送给 所述目标用户设备。 具体地， 中继 UE确定目标用设备的宏网络标识， 根 据目标用户设备的宏网络标识在网络标识映射信息中查找与之对应的目 标 UE在本组内的本地网络标识。 然后， 根据目标 UE的本地网络标识 , 将基站发送的下行数据包发送给目标 UE。 本地网络标识可以是媒介访问 控制 （ MAC ) 地址， 也可以是 IP地址。
在前述技术方案中， 组内的每个 UE都有可能成为中继 UE, 因此， 组 内的每个 UE都配置有网络标识映射信息。 UE组内 UE可以通过协商建立 所属 UE组内 UE的宏网络标识与 UE的本地网络标识的对应关系 , 建立 所属 UE组的网络标识映射信息。 也可以通过基站控制器为每个 UE下发 所属 UE组的网络标识映射信息， 具体地， UE组建立成功后， 组内 UE通 过所属基站建立的与基站控制器之间的连接。 向基站控制器上报本地组消 息 ,本地组消息包括 UE所属 UE组的组标识和 UE在所属 UE组的本地网 络标识。 基站控制器根据接收到的本地组消息， 为每个 UE组建立网络标 识映射信息。
可选地， 中继 UE根据目标 UE的宏网络标识， 将下行数据包转发给 所属 UE组内的本地网络路由设备， 通过本地网络路由设备将下行数据包 转发给目标 UE。其中，本地网络路由设备为 UE组内具有路由功能的 UE。
进一步， UE组内的中继 UE还可接收目标 UE发送给基站的上行数据 包， 并将上行数据包转发给基站。 或者， UE组内的中继 UE接收本地网 络路由设备转发的目标 UE的上行数据包， 并将上行数据包转发给基站。
图 3为本发明实施例提供的又一种数据传输方法流程图。 本实施例主 要说明： UE组内的本地网络路由设备接收到组内的中继 UE转发的下行 数据包后如何转发给目标 UE。 本地网络路由设备为 UE组内具有路由功 能的 UE或者为建立 UE组的服务器。 如图 3所示， 本实施例提供的方法 包括：
步骤 31： 本地网络路由设备接收所属 UE组内的中继 UE转发的基站 向目标 UE发送的下行数据包，下行数据包中包括目标 UE的宏网络标识， 上述本地网络路由设备为 UE组内具有路由功能的 UE。 UE组内各 UE之间通过本地网络通信。上述目标 UE的宏网络标识为 UE在所属蜂窝 网络的网络标识， 或者为目标 UE在所属蜂窝网络的逻辑信道标识， 或者 为 UE在所属蜂窝网络的网络标识和逻辑信道标识的组合。
步骤 32: 本地网络路由设备根据 UE组的网络标识映射信息和目标
UE的宏网络标识， 确定目标 UE在所属 UE组内的本地网络标识， 并根据 目标 UE的本地网络标识 , UE组的网络标识映射信息包括 UE组内每个 UE的宏网络标识与本地网络标识的对应关系。
步骤 33: 本地网络路由设备将下行数据包发送给目标 UE。
进一步， 本地网络路由设备还可接收目标设备发送的上行数据包， 并 将上行数据包发送给中继 UE, 以使中继 UE发送给网络侧设备。
图 4为本发明实施例提供的再一种数据传输方法流程图。 本实施例主 要说明： 基站控制器如何为所管理的每个基站建立 UE分组表， 以使基站 可通过目标 UE所属 UE组的中继 UE向目标 UE发送下行数据包。
步骤 41 : 基站控制器接收每个 UE发送的本地组消息， 本地组消息包 括 UE所属 UE组的组标识。
步骤 42: 基站控制器根据接收到的本地组消息， 向所管理的基站发送 归属基站的 UE分组信息， UE分组信息包括 UE的宏网络标识与 UE所属 UE组的组标识的对应关系。
UE组成功建立后，组内的 UE通过基站与基站控制器建立连接， 并通 过与基站控制器之间的连接向基站控制器上报本地组消息。 本地组消息至 少包括 UE所属 UE组的组标识。 基站控制器通过 UE上报本地组消息的 信道或者 UE与基站之间的连接， 可获知 UE在所属蜂窝网络的网络标识 和 UE归属的基站。 根据本地组消息中组标识确定 UE属于哪个 UE组。 因此， 基站控制器可根据 UE上报的本地组消息确定 UE的宏网络标识与 UE所属 UE组的组标识的对应关系， 从而为管理的各基站建立并发送归 属基站的 UE的 UE分组信息。
进一步 , 本地组消息还可包括 UE在所属 UE组内的本地网络标识。 通过 UE上 ·艮的本地网络标识， 基站控制器可确定该 UE的宏网络标识与 本地网络标识的映射关系。 基站控制器根据接收到的本地组消息， 为每个 UE组建立网络标识映射信息 ,并向每个 UE组内的 UE发送本组的网络标 识映射信息 , 每个 UE组的网络标识映射信息包括本组内 UE的宏网络标 识与 UE的本地网络标识的对应关系。 具体地， 如果釆用中继 UE直接向 目标 UE转发下行数据包的方法， 对于每个 UE组， 基站控制器需要向组 内的每个 UE发送网络标识映射信息。 如果中继 UE通过具有本地网络路 由功能的 UE向目标 UE转发下行数据包， 基站控制器向 UE组内具有本 地网络路由功能的 UE发送网络标识映射信息。
图 5Α为本发明实施例提供的再一种数据传输方法流程图。 本实施例 以 3G网络为例说明， 基站控制器如何为所管理的基站配置 UE分组信息 并为 UE配置网络标识映射信息， 以及基站向目标 UE发送的下行数据包 如何被传输到目标 UE。 本实施例适应于目标 UE所属的 UE中各个 UE均 归属同一个 NodeB。 如图 5A所示， 本实施例提供的方法包括：
步聚 la: UE组建立成功后， 组内的每个 UE通过归属的 Node B向 RNC上报本地组消息 ,本地组消息中包括 UE在蜂窝网络的宏网络标识和 UE所属 UE组的组标识。
步骤 2a: RNC根据接收到的本地组消息， 为自己管理的各个 Node B 建立并下发自己管理的 UE的 UE分组信息。
步骤 3a: RNC根据接收到的本地组消息， 为每个 UE组建立网络标识 映射信息， 并向 UE下发所属 UE组的网络标识映射信息。 每个 UE组的 网络标识映射信息包括本组内 UE的宏网络标识与 UE的本地网络标识的 对应关系。
步骤 4a: RNC向目标 UE所归属的 NodeB发送下行数据包。
步骤 5a: NodeB解析下行数据包，确定目标 UE所属 UE组的中继 UE , 在下行数据包的 MAC包头添加目标 UE在蜂窝网络的宏网络标识后， 向 目标 UE所属 UE组的中继 UE发送目标 UE的下行数据包。 NodeB在 RNC与目标 UE建立的通道上接收到下行数据包后 , 在下行数 据包的 MAC包头添加目标 UE在蜂窝网络的宏网络标识，之后向目标 UE 所属 UE组的中继 UE发送目标 UE的下行数据包。
如图 5B所示，下行数据包包括 IP层、分组数据汇聚协议 （Packet Data
Convergence Protocol, 简称 PDCP)层、 RLC层、 MAC层和物理 （ PHY ) 层。 NodeB在下行数据包的 MAC包头添加目标 UE在蜂窝网络的宏网络 标识。
步骤 6a: 中继 UE解析下行数据包的 MAC包头，根据其中的目标 UE 的宏网络标识确定自己不是目标 UE, 拆解下行数据包， 提取下行数据包 的数据服务单元（ Service Data Unit, 简称 SDU ) , 将提取的 SDU和目标 UE的宏网络标识封装到下行数据包的包头， 将下行数据包发送给本地网 络路由设备。
如图 5B所示， 中继 UE接收 NodeB发送的下行数据包后， 从下往上 依次解析 PHY层和 MAC层。 解析到 MAC层时， 中继 UE根据其中的宏 网络标识确定自己不是下行数据包的目标 UE后， 拆解下行数据包， 提取 其中的 SDU。 将该 SDU和目标 UE的宏网络标识作为 FRP帧封装到下行 数据包的包头，将封装后的下行数据包发送给本地网络路由设备。进一步， 中继 UE还可以在 FRP帧中添加用于控制中继 UE和本地网络路由设备之 间的流量的控制信息。 其中， 目标 UE的宏网络标识包括目标 UE在蜂窝 网络的网络标识和 /或 NodeB为 UE分配的逻辑信道标识。 其中 , FRP层 为本实施例定义的协议层， 用于 UE之间的通信。 图 5B中所示的 L— TNL 层， 用于本地网络之间的通信， 比如 WiFi或 BlueTooth协议。 图 5B中， 中继 UE发送给本地网络路由设备的数据中添加 FRP帧头封装在 FRP帧 中， 称为 FRP上行帧， 本地网络路由设备发送给目标 UE的数据中添加 FRP帧头封装在 FRP帧中， 称为 FRP下行帧。 FRP上行帧中包括目标 UE 的宏网络标识 （ UEID/LCHID ) , 而 FRP下行帧中不包括目标 UE的宏网 络标识。
步骤 7a: 本地网络路由设备根据所属 UE组的网络标识映射信息和目 标 UE的宏网络标识， 确定目标 UE在所属 UE组内的本地网络标识， 并 根据目标 UE的本地网络标识， 将下行数据包发送给目标 UE。 如图 5B所示， 本地网络路由设备接收到中继 UE发送的下行数据包 后， 从 FRP帧中提取出下行数据包的 SDU和目标 UE的宏网络标识， 确 定目标 UE在所属 UE组内的本地网络标识 , 根据目标 UE的本地网络标 识， 将此 SDU直接发送给目标 UE , 或者， 在下行数据包中添加该 SDU 对应的逻辑信道信息后发送给目标 UE。 目标 UE从下向上依次解析下行 数据包中的 L— TNL层、 FRP层、 RLC层和 PDCP层。 目标 UE解析到 RLC 层时， 通过其中的宏网络标识确定自己是该下行数据包的目标 UE。

图 5C为本发明实施例提供的再一种数据传输方法流程图。 本实施例 与图 5A对应实施例的区别在于， 本实施例适应于目标 UE所属的 UE组 中各个 UE归属不同基站的场景。
步骤 lb: RNC向目标 UE2发送下行数据包时， 确定 UE2所属的用户 设备组和该 UE组内的 UE1为中继 UE。
进一步， RNC向目标 UE1发送下行数据包时， 确定 UE1所属 UE组 的 UE2为信号质量最好的中继 UE, 向 UE2所归属的 NodeB2发送下行数 据包， 使得 UE2作为中继 UE协助 RNC与 UE 1之间的通信。
步骤 2b: RNC在下行数据包的 RLC包头中添加 UE2在蜂窝网络的宏 网络标识后， 向 UE1所归属的 NodeBl发送下行数据包。
步骤 3b: NodeBl将下行数据包数据发送给 UEl。
RNC在与 UEl建立的通道上向 NodeBl发送目标 UE为 UE2的下行 数据包， NodeBl在与 UEl建立的通道上接收到下行数据包后， 向 UE1转 发下行数据包。
如图 5D所示， UE1和 UE2归属于不同的 NodeB。 RNC发送的下行 数据包分为 IP层、 PDCP层、 RLC层。 RNC将 UE2的宏网络标识 ( UEID/LCHID ) 填充到下行数据包的 RLC层中发送给 UE1归属的 NodeBl , NodeBl对下行数据包进行处理后， 为下行数据包封装 MAC层 和 PHY层后， 将下行数据包发送给 UE1。
步骤 4b: UE1解析下行数据包的 RLC包头， 根据其中的目标 UE的 网络标识确定自己不是目标 UE, 拆解下行数据包， 提取下行数据包的 SDU, 将提取的 SDU和目标 UE的宏网络标识封装到下行数据包的包头， 将封装后的下行数据包发送给本地网络路由设备。
如图 5D所示， UE1解析 RLC层时， 根据 RLC包头中的宏网络标识 确定自己不是下行数据包的目标 UE后， 拆解下行数据包， 提取其中的 SDU, 将提取的 SDU和 UE2的宏网络标识封装到下行数据包。 进一步， UE1还可以在 FRP帧中添加用于控制 UE1和本地网络路由设备之间的流 量的控制信息。 其中， UE2的宏网络标识包括 UE2在蜂窝网络的网络标 识和 /或基站为 UE分配的逻辑信道标识。 之后， UE1将处理后的下行数据 包发送给本地网络路由设备。
步骤 5b: 本地网络路由设备根据所属 UE组的网络标识映射信息和目 标 UE2的宏网络标识 , 确定目标 UE在所属 UE组内的本地网络标识 , 并 根据目标 UE2的本地网络标识， 将下行数据包发送给目标 UE2。

可选地， UE1解析下行数据包的 RLC包头，根据其中的目标 UE的宏 网络标识确定自己不是目标 UE2时，还可根据所属 UE组的网络标识映射 信息， 确定与下行数据包中目标 UE2的宏网络标识对应的目标 UE2的本 地网络标识， 并根据目标 UE的本地网络标识， 将下行数据包发送给目标 UE2。
本实施例中， RNC向目标 UE发送下行数据包时，可以根据实际需求， 确定是由目标 UE归属的 NodeB确定目标 UE所属 UE组的中继 UE, 还 是自己确定上述中继 UE。 如果是为了提高目标 UE的可靠性， 由 RNC确 定目标 UE所属 UE组的中继 UE, 并向中继 UE所归属的 NodeB发送下 行数据包， 以避免中继 UE与目标 UE归属于不同的 NodeB时， 目标 UE 所属的 NodeB无法寻址到中继 UE的问题。 如果为了提高目标 UE的通信 可靠性， 可由目标 UE归属的 NodeB确定目标 UE所属 UE组的中继 UE。
