实施例 1 本发明实施例提供一种用户设备上下文的识别方法, 其中用户设备 从第二基站向第一基站切换; 本实施例应用于第一基站侧。
图 1是本发明实施例的识别方法的流程图, 如图 1所示, 该识别方 法包括:
歩骤 101, 第一基站获得用户设备的第一终端标识, 其中该第一终端 标识由该用户设备发生连接失败后向网络侧发送;
歩骤 102,第一基站根据第一终端标识在该用户设备的上下文中査找 对应于第二基站的第二终端标识;
歩骤 103, 第一基站向第二基站发送包含第二终端标识的切换报告, 使得第二基站根据第二终端标识査找该用户设备的上下文。
在本实施例中, 第一基站可以是切换的目标基站, 是切换报告 (Handover Report, 具体内容可以参考【TS36.423】) 的发送者; 第二基 站时切换的源基站, 是切换报告的接收者。 用户设备从第二基站向第一 基站切换, 并经历了连接失败, 例如可以是链路失败 RLF、 也可以是切 换失贝夂 (HOF, Handover Failure )。
在本实施例中, 可以在如下情形下执行歩骤 102和 103, 例如切换报 告类型是切换太早 (too early) 或切换到错误小区; 或者连接失败类型是 链路失败;或者连接失败后无线资源控制(RRC, Radio Resource Control) 连接重建不成功。 但本发明不限于此, 可以根据实际情况确定执行条件。
在本实施例中, 用户设备在发生连接失败后, 可以向网络侧发送第 一终端标识, 例如在发送 RLF报告时携带 UE— identity— 1信息。 其中, 第 一终端标识可以是小区无线网络临时标识 C-RNTI、或者短媒体接入控制 标识 shortMAC-I (具体内容可以参考 【TS36.331】)、 或者 C-RNTI 和 shortMAC-L 但本发明不限于此, 可以根据实际情况确定具体的信息。
在本实施例中, 第一基站可以获得用户设备的第一终端标识。 可以 通过直接接收该用户设备发送的 RLF报告, 来获得该用户设备的第一终 端标识; 或者, 还可以从网络侧的其他基站发送的消息中来获得该用户 设备的第一终端标识。
在本实施例中, 第一基站获得该第一终端标识后, 可以判断该第一 终端标识是否是自己分配给该用户设备的 C-RNTI 1, 或者是否是对应于 该第一基站的 shortMAC-I— 1。 如果是, 则该第一基站可以根据第一终端 标识在该用户设备的上下文中进行査找, 找到对应于第二基站的第二终 端标识。
其中, 第二终端标识可以是小区无线网络临时标识 C-RNTI、 或者短 媒体接入控制标识 shortMAC-I、 或者 C-RNTI和 shortMAC-I。 但本发明 不限于此, 可以根据实际情况确定具体的信息。
在本实施例中, 第一基站可以将査找到的第二终端标识 (例如第二 基站为该用户设备分配的 C-RNTI— 2, 或者该用户设备由第二基站切换到 第一基站时生成的 shortMAC-I— 2) 加入到切换报告中。 第一基站可以在 从其他基站接收到 RLF 指示 (RLF Indication , 具体内容请参见 【TS36.423】) 之后, 将该切换报告发送给第二基站。
在本实施例中, 第二基站接收到切换报告之后, 可以根据第二终端 标识査找该用户设备的上下文。
由上述实施例可知, 通过目标基站将源基站对应的终端标识发送给 源基站, 可以使得源基站根据对应的终端标识査找该用户设备的上下文。 实施例 2

在本实施例中, 第一基站可以是切换的目标基站, 是切换报告的发 送者; 第二基站是切换的源基站, 是切换报告的接收者。 用户设备从第 二基站向第一基站切换, 并经历了连接失败, 例如可以是链路失败 RLF、 也可以是切换失败 HOF。
在本实施例中, 当用户设备从第二基站向第一基站切换时, 第二基 站可以在切换准备过程中接收到切换请求确认 (Handover Request Acknowledge) 消息 (具体内容可以参见【TS36.423】)。 第二基站可以读 取该切换请求确认消息, 来获取对应于第一基站的第一终端标识。
其中, 第一终端标识可以是小区无线网络临时标识 C-RNTI、 或者短 媒体接入控制标识 shortMAC-I、 或者 C-RNTI和 shortMAC-I。 但本发明 不限于此, 可以根据实际情况确定具体的信息。
在本实施例中,第二基站可以存储该第一终端标识(例如 C-RNTI— 1, 或者 shortMAC-I— 1 ), 从而将该第一终端标识与该用户设备联系起来。例 如, 可以为该第一终端标识与该用户设备建立映射关系, 可以将该第一 终端标识与该用户设备的对应于该第二基站的第二终端标识 (例如 C-RNTI 2, 或者 shortMAC-I— 2) 联系起来。
在本实施例中, 当第二基站在接收到包含第一终端标识的切换报告 时, 可以根据第一终端标识査找该用户设备的上下文。
由上述实施例可知, 通过源基站从切换请求确认消息中获取目标基 站对应的终端标识, 可以使得源基站将该用户设备与对应于目标基站的 终端标识联系起来; 由此, 源基站在接收到切换报告时, 可以根据该终 端标识査找该用户设备的上下文。 实施例 3
本发明实施例提供一种用户设备上下文的识别方法, 应用于用户设 图 3是本发明实施例的识别方法的又一流程图, 如图 3所示, 该识 别方法包括:
歩骤 301, 用户设备存储第二终端标识, 该第二终端标识在该用户设 备收到切换命令后生成;
歩骤 302, 用户设备发送链路失败报告, 使得接收到该链路失败报告 的基站査找该用户设备的上下文。
在本实施例中, 与现有技术不同的是, 用户设备收到切换命令 (Handover Command, 具体内容可以参考【TS36.331】)后, 可以生成第 二终端标识。 该第二终端标识可以是用户设备收到该切换命令后, 所在 的基站为该用户设备分配的 C-RNTI、或者也可以是用户设备从源小区切 换到目标小区时生成的 shortMAC-I、或者可以是 C-RNTI和 shortMAC-I。
在本实施例中, 用户设备可以在连接失败 (例如链路失败 RLF或者 切换失败 HOF ) 之后, 发送链路失败报告。 至于具体如何实施可以参考 现有技术。
在一个实施方式中, 在发生连接失败 (例如 RLF或者 HOF ) 之后, 用户设备可以将第二终端标识添加到 RLF报告中, 并将该 RLF报告发送 至网络侧。 接收到该 RLF报告的基站可以根据该第二终端标识査找该用 户设备的上下文, 并且可以对移动性能的参数进行优化。

歩骤 401, 用户设备存储第二终端标识, 该第二终端标识在该用户设 备收到切换命令后生成;
歩骤 402, 用户设备发送包含第二终端标识的链路失败报告, 使得接 收到该链路失败报告的基站根据该第二终端标识査找该用户设备的上下 文。
在另一个实施方式中, 用户设备可以具有计时器。 该定时器可以根 据切换命令而启动, 但本发明不限于此, 可以根据实际情况确定具体的 实施方式。
图 5是本发明实施例的识别方法的又一流程图, 如图 5所示, 该识 别方法包括:
歩骤 501, 用户设备存储第二终端标识, 该第二终端标识在该用户设 备收到切换命令后生成。
歩骤 502, 用户设备在发生连接失败时, 判断计时器是否超过预设时 间。 若计时器没有超时则执行歩骤 503 ; 若计时器超时则执行歩骤 504。
其中, 计时器可以根据切换命令而启动, 例如可以在用户设备完成 切换之后 (如成功发送 RRCCorniectionReconfiguratk Compiete、消息、, 具 体内容可以参考【TS36.331】) 启动计时器。 计时器的预设时间可以由基 站配置, 也可以是协议指定, 或者也可以由用户设备自己产生。
歩骤 503, 用户设备发送包含第二终端标识的链路失败报告, 使得基 站根据第二终端标识査找该用户设备的上下文。
歩骤 504, 用户设备发送包含第一终端标识的链路失败报告, 使得基 站根据第一终端标识査找用户设备的上下文。
其中, 该第一终端标识在用户设备发生链路失败时生成, 或者在发 生链路失败后进行 RRC连接重建时生成。 第一终端标识具体可以为: 小 区无线网络临时标识 C-RNTI和 /或短媒体接入控制标识 shortMAC-I。
在本实施例中, 由于该第二终端标识在用户设备收到切换命令后生 成, 当第二终端标识具体为短媒体接入控制标识 shortMAC-I时, 即使出 现基站分配了重复的 C-RNTI 的情况, 也能唯一识别该用户设备的上下 文。
由上述实施例可知, 通过在用户设备收到切换命令后生成终端标识, 可以使得基站根据该终端标识识别用户设备的上下文, 并对移动性能的 参数进行优化。 实施例 4
