下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
本发明实施例中, 当两个或多个 UE ( user equipment, 用户设备 )都具有同 时支持某种短距离通信技术和某种蜂窝通信技术,这些 UE可以建立一种 MUCC 的关系。其中短距离通信技术可以例如 WiFi ( wireless fidelity ,无线相容性认证 ) 或 BlueTooth(蓝牙技术;),蜂窝通信技术如 LTE( Long Term Evolution,长期演进), 3G UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统 ) 或 CDMA ( Code Division Multiple Access, 码分多址), 2G GSM ( global system for mobile communications , 全球移动通信系统 ) , WiMAX ( Worldwide Interoperability for Microwave Access, 全球敫波互联接入)等。 比如其中一个 UE 需要发送或接收数据, 为了增加可靠性和吞吐率, 可以有额外一个或多个 UE (我们可以称为支撑 UE, 或协助 UE, 用来协助受益 UE而进行数据中转的 UE )对该 UE (我们称为受益 UE, 或被协助 UE, 为数据最终的发送 /接收方和 使用方)进行支撑, 协助其通信, 这些 UE处于相同的短距离连接范围内, 那么 对于下行数据来说, 网络可以将下行数据分别发送给这些 UE (一种优化的方法 是, 网络调度总会选择当时无线链路情况最好的 UE发送), 如果数据不是到达 最终受益 UE,那么接收到数据的支撑 UE再将数据通过短距离通信(例如 WiFi ) 发送给受益 UE。 当然, 数据也可以是直接到达受益 UE的。 受益 UE可进行数 据的合并。 同理, 受益 UE的上行数据也可以通过受益 UE 自身或者其他支撑 UE发给网络, 然后网络进行数据的合并, 完成 UE之间的协作通信。 受益 UE 和支撑 UE的概念是从受益 UE的某一承载角度来看的。 例如, UE1和 UE2组 成 MUCC, 它们可以相互协助通信, 这样, 站在 UE1的某个承载角度, UE2可 以支撑 UE1的该承载, 于是 UE1是受益 UE, UE2是支撑 UE。 而于此同时, UE1也可以支撑 UE2的某个承载, 于是站在 UE2的这个承载的角度, UE2是受 益 UE, 而 UE1是支撑 UE。
图 1 是本发明实施例中一种协作通信系统的组成结构示意图。 如图所示本 发明中的协作通信系统包括源基站 10和切换目标基站 20, 其中源基站 10下包 括至少一对协作通信设备一作为通信数据中转设备的支撑设备 50和作为通信数 据目的设备的受益设备 40, 还可以包括其他的协作通信设备, 而所述支撑设备 50还可以对应有其他的受益设备, 受益设备 40也还可以有其他的支撑设备, 其 中:
源基站 10用于获取支撑设备 50和受益设备 40的上报信息, 根据支撑设备 50和受益设备 40的上报信息可以确认支撑设备 50或受益设备 40是否需要进行 通信切换, 本发明实施例中的上 信息包括并不限于当前所在小区以及相邻小 区的信号质量或强度等信息, 若当前所在小区的信号质量或强度低于某一阈值, 或与相邻小区相比较差, 并且差值超过某一阈值, 则可以确认支撑设备 50或受 益设备 40需要进行通信切换。 在确认支撑设备 50或受益设备 40需要进行通信 切换后, 即可分别向双方发送连接配置消息, 以使支撑设备 50和受益设备 40 释放协作相关的承载上下文。 在本发明实施例中支撑设备 50或受益设备 40可 以切换至切换目标基站 20下。 本发明实施例中的承载上下文指的是空口承载的 相关信息, 主要包括建立空口承载的协议栈中的相关配置参数, 分别保存在承 载两端设备上, 承载上下文可以包括协作承载上下文和非协作承载上下文, 其 中非协作承载上下文即设备为了自身通信与基站间建立的空口承载的相关信 息, 协作承载上下文包括支撑设备为了协作受益设备而与基站间建立的空口承 载的相关信息以及支撑设备与受益设备之间的短距离承载的相关信息。

第二配置模块 204用于当所述切换确认模块 202确认所述第一通信设备需 要进行通信切换时向第二通信设备发送连接配置消息, 以使所述第二通信设备 释放与第一通信设备之间的协作承载上下文以及与源基站之间的协作承载上下 文。 所述第二通信设备为所述第一通信设备的协作通信设备, 若所述第一通信 设备是支撑设备时, 其协作通信设备即第二通信设备为受益设备, 在所述第二 通信设备是受益设备时, 其协作通信设备即第二通信设备为支撑设备。 具体的, 所述第二配置模块 204向第二通信设备发送的连接配置消息可以为 RRC的连接 重配消息, 指示第二通信设备进行承载上下文的重新配置, 包括释放需要进行 重配的承载上下文, 本实施例中为指示第二通信设备释放与第一通信设备之间 的协作承载上下文以及与源基站之间的协作承载上下文。 第二通信设备的承载 上下文包括协作承载上下文和非协作承载上下文, 其中第二通信设备的协作承 载上下文包括与第一通信设备之间的协作承载上下文以及与源基站之间的协作 承载上下文, 当第二通信设备还与其他通信设备存在协作通信关系时, 还包括 与其他协作通信设备之间的协作承载上下文。 可选的, 第二配置模块 204在向 第二通信设备发送连接配置消息后可以重新为第二通信设备进行通信协调配 对。

图 5 是本发明另一实施例中的源基站的组成结构示意图。 如图所示本实施 例中的源基站至少包括: 上报信息获取模块 501、 切换确认模块 502、 第一配置 模块 503、 第二配置模块 504、 切换请求发送模块 505、 切换应答接收模块 506、 第一判断模块 507以及无线网络临时标识保存模块 508, 其中:
上报信息获取模块 501用于获取第一通信设备和第二通信设备的上报信息, 所述上 信息可以包括所述第一通信设备和第二通信设备分别的当前所在小区 以及相邻小区的信号质量或强度等信息。 其中所述第一通信设备和第二通信设 备相互为协作通信设备, 第一通信设备为本实施例中首先需要进行通信切换的 通信设备, 可以为支撑设备或受益设备, 第二通信设备为所述第一通信设备的 协作通信设备, 若所述第一通信设备是支撑设备时, 其协作通信设备即第二通 信设备为受益设备, 在所述第二通信设备是受益设备时, 其协作通信设备即第 二通信设备为支撑设备。
切换确认模块 502用于分别根据所述第一通信设备和第二通信设备的上报 信息确定所述第一通信设备和第二通信设备是否需要进行通信切换。 由于第一 通信设备与第二通信设备在不同实施例中可以是支撑设备或受益设备, 本实施 例中, 将两者中首先确认需要进行通信切换的通信设备设为第一通信设备, 它 的协作通信设备为第二通信设备。
切换请求发送模块 505 ,用于当切换确认模块 502确认第一通信设备需要进 行通信切换时向所述第一通信设备的切换目标基站发送切换请求消息, 针对第 一通信设备的切换请求消息包括源基站的与所述第一通信设备之间的第一承载 上下文; 以及当切换确认模块 502确认第二通信设备需要进行通信切换时切换 请求发送模块 505用于向所述第二通信设备的切换目标基站发送切换请求消息, 针对第二通信设备的切换请求消息可以包括源基站的与第二通信设备之间的第 一承载上下文, 还可以包括无线网络临时标识保存模块 508在与所述第二通信 设备之间的承载上下文中保存的所述第一通信设备的切换目标基站的基站标识 以及所述第一通信设备的切换目标基站为所述第一通信设备分配的无线网络临 时标识, 目的是通知第二通信设备的切换目标基站当前请求切换的第二通信设 备的协作通信设备在之前进行过通信切换。 进而, 所述第一通信设备的切换目 标基站与第二通信设备的切换目标基站可以为同一个目标基站, 也可以为不同 的目标基站。 若第二通信设备的切换目标基站与第一通信设备的切换目标相同, 表示第二通信设备切换到了与第一通信设备同一个目标基站, 那么它们的切换 目标基站可以为它们做通信协作配对。 进一步的, 在本实施例中所述切换请求 消息中源基站的与第一通信设备或第二通信设备之间的承载上下文可以包括非 协作承载上下文以及协作承载上下文, 即把第一通信设备或第二通信设备的所 有承载上下文均切换至切换各自的目标基站。

无线网络临时标识保存模块 508用于在与所述第二通信设备之间的承载上 下文中保存所述第一通信设备的切换目标基站的基站标识以及所述第一通信设 备的切换目标基站为所述第一通信设备分配的无线网络临时标识。 具体的, 当 切换应答接收模块 506接收到第一通信设备的切换目标基站发送的切换应答消 息后, 源基站的无线网络临时标识保存模块 508就将第一通信设备的切换目标 基站的基站标识及其为所述第一通信设备分配的无线网络临时标识保存在源基 站的与第二通信设备之间的承载上下文中。
第一配置模块 503用于当切换应答接收模块 506接收到第一通信设备的切 换目标基站发送的切换应答消息后, 向第一通信设备发送连接配置消息, 当切 换应答接收模块 506接收到第二通信设备的切换目标基站发送的切换应答消息 后, 向第二通信设备发送连接配置消息。 具体的, 向第一通信设备发送的连接 配置消息中携带所述第一通信设备的切换目标基站为所述第一通信设备分配的 第二承载上下文, 指示第一通信设备释放与源基站之间的协作承载上下文并指 示第一通信设备根据所述第一通信设备的切换目标基站为所述第一通信设备分 配的第二承载上下文向所述第一通信设备的切换目标基站发起随机接入流程。 当切换确认模块 502确认第二通信设备需要进行通信切换时第一配置模块向第 二通信设备发送的连接配置消息同理类似, 不再赘述。 具体的, 所述第一配置 模块 503 向第一通信设备或第二通信设备发送的连接配置消息可以为 RRC ( Radio Resource Control , 无线资源控制协议 )的连接重配消息, 指示第一通信 设备或第二通信设备进行承载上下文的重新配置, 包括释放需要进行重配的承 载上下文, 本实施例中为指示第一通信设备或第二通信设备释放与源基站之间 的协作承载上下文。
第二配置模块 504用于当第一判断模块 507得到肯定的判断结果后向第二 通信设备发送连接配置消息, 以使所述第二通信设备释放与第一通信设备之间 的协作承载上下文以及与源基站之间的协作承载上下文。
