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。
图 1是本发明实施例提供的一种重定向处理方法的流程示意图, 如图 1所 示, 包括如下步骤。
101、 当 UE重定向失败的次数超过第一阈值时,第一设备通过 S1接口向第 一基站发送第一消息, 所述第一基站为所述 UE的服务基站, 所述第一消息用于 指示所述基站禁止对所述 UE进行同系统和 /或异系统的重定向。
可选的, UE的重定向失败次数超过第一阈值, 具体是 UE的异系统的重定 向的次数超过第一阈值, 这时第一设备通过 S 1接口向第一基站发送第一消息, 以指示所述基站至少禁止对所述 UE进行异系统的重定向。
可选的, UE的重定向失败次数超过第一阈值, 具体是 UE的同系统的重定 向的次数超过第一阈值,这时第一设备就通过 S 1接口向第一基站发送第一消息, 以指示所述基站至少禁止对所述 UE进行同系统的重定向。
可选的, UE的重定向失败次数超过第一阈值, 具体是 UE的同系统和异系 统的重定向的次数超过第一阈值, 这时第一设备就通过 S1接口向第一基站发送 第一消息, 以指示所述基站禁止对所述 UE进行同系统和 /或异系统的重定向。
作为一种可选的实施方式,在步骤 101之前, 第一设备会累计所述 UE的重 定向失败次数, 当累计的次数超过第一阈值时, 步骤 101第一设备就通过 S1接 口向第一基站发送第一消息。
作为一种可选的实施方式, 所述第一阈值具体可以为所述第一设备预先设 置的阈值, 具体可以是根据不同 UE灵活设置不同的阈值。 例如, UE1的签约等 级高于 UE2的签约等级时,所述第一设备就可以将相对于 UE1的第一阈值设置 为 3次, 也就是当 UE1的重定向失败次数超过 3次时, 所述第一设备就通过 S1 口向第一基站发送第一消息, 当第一基站接收到该消息时就禁止对 UE1进行同 系统和 /或异系统的重定向; 所述第一设备可以将相对于 UE2的第一阈值设置为 小于 UE1的第一阈值,例如 1次,也就是当 UE2的重定向失败次数超过 1次时, 第一基站就禁止对 UE2进行同系统和 /或异系统的重定向。
作为一种可选的实施方式, 所述第一消息具体可以是第一列表, 所述第一 列表包括: 系统标识, 所述系统标识对应的系统为所述第一设备指示所述基站 禁止所述 UE进行异系统的重定向的目标系统; 和 /或, 小区标识, 所述小区标 识对应的小区为所述第一设备指示所述基站禁止所述 UE 进行同系统的重定向
的目标小区。
所述系统标识对应的系统与所述基站所属的系统不同, 所述小区标识对应 的小区所属的系统与所述基站所属的系统相同。 当所述第一基站接收到所述第 一列表后,就禁止所述 UE对所述第一列表包含的系统标识对应的系统进行异系 统的重定向, 和 /或, 禁止所述 UE对所述第一列表包含的小区标识对应的小区 进行同系统的重定向。
该实施方式中, 所述第一列表还可以包括: 与所述基站所属的系统不同、 且被所述 UE支持的全部或部分系统对应的系统标识, 和 /或, 与所述基站所属 的系统相同、 且被所述 UE支持的全部或部分小区对应的小区标识。
可选的, 第一列表包括的系统标识和小区标识可以根据不同情况而灵活设 置, 如当 UE处于 LTE网络系统时, UE可以进行异系统的重定向和同系统的重 定向 ,第一设备根据记录的该 UE的重定向失败次数,如记录的 UE从 LTE网络 系统至 GSM的异系统的重定向的失败次数为 5 , 而 UE从 LTE网络系统至通用 移动通信系统 ( Universal Mobile Telecommunications System, UMTS )的异系统 重定向的失败次数为 2 ,则第一设备可以设备第一列表只包括 GSM的系统标识, 也就是只指示第一基站禁止 UE对 GSM进行异系统的重定向。 同理, 同系统的 重定向也可以是根据不同小区之间的重定向的失败次数, 第一设备灵活设置第 一列表, 以提升用户体验。
作为一种可选的实施方式,所述第一列表具体可以为禁止切换制式列表(例 如: Forbidden inter RATs ) ,所述禁止切换制式列表包括系统标识和 /或 d、区标识, 所述系统标识对应的系统为所述第一设备指示所述基站禁止所述 UE进行异系 统的重定向的目标系统, 所述小区标识对应的小区为所述第一设备指示所述基 站禁止所述 UE进行同系统的重定向的目标小区。
该实施方式中, 所述禁止切换制式列表可以是包含在切换限制列表(例如: Handover Restriction List ) 中, 步骤 101具体可以是第一设备通过 S1接口向第 一基站发送所述切换限制列表, 所述第一基站为所述 UE的服务基站, 所述切换 限制列表包含禁止切换制式列表, 所述禁止切换制式列表包含系统标识和 /或小 区标识,所述系统标识对应的系统为所述第一设备指示所述基站禁止所述 UE进 行异系统的重定向的目标系统, 所述小区标识对应的小区为所述第一设备指示 所述基站禁止所述 UE进行同系统的重定向的目标小区。
由于所述切换限制列表包含系统标识和 /小区标识的禁止切换制式列表, 且 所述系统标识对应的系统为所述第一设备指示所述基站禁止所述 UE进行异系 统的重定向的目标系统, 所述小区标识对应的小区为所述第一设备指示所述基 站禁止所述 UE进行同系统的重定向的目标小区,这样可以保持 UE业务的连续 性, 同时还可以节约网络资源。
作为一种可选的实施方式, 所述第一消息具体可以为初始上下文请求消息 (例如: Initial Context Setup Request )或下行非接入层 NAS传输消息 (例如: Downlink Non Access Stratum Transport ), 也就是说, 在所述初始上下文请求消 息或所述下行非接入层 NAS传输消息中指示所述基站禁止对所述 UE进行同系 统和 /或异系统的重定向。
步骤 101具体可以是第一设备通过 S1接口向第一基站发送所述初始上下文 请求消息或所述下行非接入层 NAS传输消息, 所述第一基站为所述 UE的服务 基站, 所述初始上下文请求消息或所述下行非接入层 NAS传输消息包含系统标 识和 /或小区标识, 所述系统标识对应的系统为所述第一设备指示所述基站禁止 所述 UE进行异系统的重定向的目标系统,所述小区标识对应的小区为所述第一 设备指示所述基站禁止所述 UE进行同系统的重定向的目标小区。
具体的可以是在所述初始上下文请求消息或所述下行非接入层 NAS传输消 息携带系统标识和小区标识, 所述系统标识对应的系统为所述第一设备指示所 述基站禁止所述 UE进行异系统的重定向的目标系统,所述小区标识对应的小区 为所述第一设备指示所述基站禁止所述 UE进行同系统的重定向的目标小区。这 样在指示所述基站禁止所述 UE进行重定向时,无需得建立指示消息,可以采用 现有过程中的初始上下文请求消息或下行非接入层 NAS传输消息携带系统标识 和小区标识, 以指示所述基站禁止所述 UE进行重定向。 这样可以保证 UE业务 的连续性, 并进而提高用户体验。
该实施方式中, 上述初始上下文请求消息或所述下行非接入层 NAS传输消 息具体可以为所述 UE的跟踪区更新( Tracking Area Update, TAU )过程或在所 述 UE的服务请求(例如: Service Request )过程中通过 S1口发送的初始上下文 请求消息或下行非接入层 NAS传输消息。
在上述过程中会把所述初始上下文请求消息或所述下行非接入层 NAS传输 消息发送至所述基站。 由于所述初始上下文请求消息或下行非接入层 NAS传输
消息携带系统标识和小区标识, 所述系统标识对应的系统为所述第一设备指示 所述基站禁止所述 UE进行异系统的重定向的目标系统,所述小区标识对应的小 区为所述第一设备指示所述基站禁止所述 UE进行同系统的重定向的目标小区。 当所述基站接收到所述初始上下文请求消息或所述下行非接入层 NAS传输消息 后, 就禁止所述 UE进行同系统和 /或异系统的重定向。
上述 TAU过程和服务请求过程以及 TAU流程和服务请求过程中 S1口的初 始上下文请求消息, 都是现有的, 此处不作详细说明。 这样保持所述 UE业务连 续性的同时, 还可以节约网络资源。
该实施方式中, 所述初始上下文请求消息或所述下行非接入层 NAS传输消 息具体可以携带上述禁止切换制式列表, 所述禁止切换制式列表包括系统标识 和 /或小区标识, 所述系统标识对应的系统为所述第一设备指示所述基站禁止所 述 UE进行异系统的重定向的目标系统,所述小区标识对应的小区为所述第一设 备指示所述基站禁止所述 UE进行同系统的重定向的目标小区。
该实施方式中, 所述初始上下文请求消息或所述下行非接入层 NAS传输消 息具体还可以携带上述切换限制列表, 所述切换限制列表包含上述禁止切换制 式列表, 所述禁止切换制式列表包括系统标识和 /或小区标识, 所述系统标识对 应的系统为所述第一设备指示所述基站禁止所述 UE 进行异系统的重定向的目 标系统,所述小区标识对应的小区为所述第一设备指示所述基站禁止所述 UE进 行同系统的重定向的目标小区。
作为一种可选的实施方式, 本实施例中第一设备具体可以是移动管理设备 ( Mobility Management Entity, MME )。
上述技术方案中, 当 UE重定向失败的次数超过第一阈值时, 第一设备通过 S1接口向第一基站发送第一消息, 所述第一基站为所述 UE的服务基站, 所述 第一消息用于指示所述基站禁止对所述 UE进行同系统和 /或异系统的重定向, 可以减少 UE的重定向失败率, 并进而提高用户体验。
图 2是本发明实施例提供的另一种重定向处理方法的流程示意图, 如图 2 所示包括如下步骤。
201、 当 UE重定向失败的次数超过第一阈值时,第一设备通过 S1接口向第 一基站发送第一消息, 所述第一基站为所述 UE的服务基站, 所述第一消息用于 指示所述基站禁止对所述 UE进行同系统和 /或异系统的重定向。
步骤 201具体可以采用上面实施例描述的步骤 101的实施方式。
202、 当第一定时器超时时, 所述第一设备向所述第一基站发送第二消息, 所述第二消息用于指示所述第一基站取消禁止对所述 UE进行重定向 ,或者指示 允许所述第一基站接收到所述 UE发送的重定向请求时,对所述 UE进行重定向; 其中, 所述第一定时器是在所述第一设备通过 S1接口向第一基站发送第一消息 时启动的。
当步骤 201第一设备向所述基站发送通过 S1接口向第一基站发送第一消息 时就启动第一定时器, 该定时器的时长具体可以是根据不同 UE设置不同的时 长, 如根据 UE的签约等级不同, 设置该定时器的时长不同。 在该定时器专超时 时, 第一设备向所述第一基站发送第二消息, 所述第二消息用于指示所述第一 基站取消禁止对所述 UE 进行重定向, 或者指示允许所述第一基站接收到所述 UE发送的重定向请求时, 对所述 UE进行重定向。 这样在该定时器时长内, UE 的同系统和 /异系统的重定向是被禁止的, 所以减少的 UE的重定向失败率。
当所述基站接收到第二消息时就取消禁止对所述 UE进行重定向,或当所述 基站接收到第二消息后, 当接收到所述 UE发送的重定向请求时, 对所述 UE进 行重定向。这样可以实现只禁止 UE—段时间不能进行重定向操作,从而不影响 UE的业务。
作为一种可选的实施方式, 当第一设备通过 S 1接口向第一基站发送第一消 息时就启动第一定时器, 若所述计时器未超过第一预设时间阈值时, 则监测所 述计时器的监测单元监测所述计时器, 当监测到所述计时器超过第一预设时间 阈值时, 第一设备就向所述基站发送第二消息, 指示所述第一基站取消禁止对 所述 UE进行重定向,或者指示允许所述第一基站接收到所述 UE发送的重定向 请求时, 对所述 UE进行重定向。
作为一种可选的实施方式, 所述第二消息具体可以是第二列表, 所述第二 列表包括: 系统标识, 所述系统标识对应的系统为所述第一设备指示所述基站 允许所述 UE进行异系统的重定向的目标系统; 和 /或, 小区标识, 所述小区标 识对应的小区为所述第一设备指示所述基站允许所述 UE 进行同系统的重定向 的目标小区; 或者, 所述第二消息包括内容为空的第一列表, 所述第一列表用 于保存: 系统标识, 所述系统标识对应的系统为所述第一设备指示所述基站禁 止所述 UE进行异系统的重定向的目标系统; 和 /或, 小区标识, 所述小区标识
对应的小区为所述第一设备指示所述基站禁止所述 UE 进行同系统的重定向的 目标小区。
其中, 所述系统标识对应的系统与所述基站所属的系统不同, 所述小区标 识对应的小区所属的系统与所述基站所属的系统相同。 当所述第一基站接收到 所述第二列表后,基站允许所述 UE进行相对于所述第二列表所包含的系统标识 对应的系统, 和 /或, 所述第二列表所包含的小区标识对应的小区的同系统和 /或 异系统的重定向。如所述第二列表包含 GSM对应系统标识和 LTE网络系统小区 1对应的小区标识, 当所述基站接收到所述第二列表时, 就可以允许所述 UE进 行相对于 GSM的异系统的重定向 ,和相对于 LTE网络系统小区 1的同系统的重 定向。
当所述第二消息包括内容为空的第一列表, 所述第一列表用于保存: 系统 标识, 和 /或, 小区标识; 所述系统标识对应的系统为所述第一设备指示所述基 站禁止所述 UE进行异系统的重定向的目标系统,所述小区标识对应的小区为所 述第一设备指示所述基站禁止所述 UE进行同系统的重定向的目标小区。而第二 消息包括的第一列表的内容为空, 也就是第一设备指示所述基站不禁止所述 UE 进行同系统和 /或异系统的重定向。 所述第一列表具体可以采用上面实施例描述 的第一列表。
可选的, 该实施方式中, 步骤 202具体可以包括: 当第一定时器超时时, 所述第一设备向所述第一基站发送所述第二列表, 所述第二列表包括: 系统标 识, 和 /或, 小区标识; 所述系统标识对应的系统为所述第一设备指示所述基站 允许所述 UE进行异系统的重定向的目标系统,所述小区标识对应的小区为所述 第一设备指示所述基站允许所述 UE进行同系统的重定向的目标小区。其中, 所 述第一定时器是在所述第一设备通过 S1 接口向第一基站发送第一消息时启动 的。
可选的, 该实施方式中, 步骤 202具体还可以包括: 当第一定时器超时时, 所述第一设备向所述第一基站发送内容为空的第一列表, 所述第一列表用于保 存: 系统标识, 和 /或, 小区标识; 所述系统标识对应的系统为所述第一设备指 示所述基站禁止所述 UE进行异系统的重定向的目标系统,所述小区标识对应的 小区为所述第一设备指示所述基站禁止所述 UE 进行同系统的重定向的目标小 区。
可选的, 当所述基站接收到所述第二消息 (例如: 第二列表或内容为空的 第一列表)后, 就取消禁止对所述 UE进行重定向, 当所述第一基站接收到所述 UE发送的重定向请求时, 对所述 UE进行重定向。 这样可以实现只禁止 UE在 一段时间内进行同系统和 /或异系统的重定向, 当第一定时器超时时, 就取消禁 止对 UE进行重定向 , 从而保证减少 UE的重定向失败率的同时, 可以保证 UE 可以进行重定向, 以完成 UE的业务。
作为一种可选的实施方式, 所述第二消息具体可以为初始上下文请求消息 或下行非接入层 NAS传输消息, 也就是说, 在所述初始上下文请求消息或所述 下行非接入层 NAS传输消息中指示所述第一基站取消禁止对所述 UE进行重定 向, 或者指示允许所述第一基站接收到所述 UE发送的重定向请求时, 对所述 UE进行重定向。
可选的, 步骤 202具体可以包括: 当第一定时器超时时, 第一设备通过 S1 接口向第一基站发送所述初始上下文请求消息或所述下行非接入层 NAS传输消 息, 所述第一基站为所述 UE的服务基站, 所述初始上下文请求消息或所述下行 非接入层 NAS传输消息中指示所述第一基站取消禁止对所述 UE进行重定向, 或者指示允许所述第一基站接收到所述 UE发送的重定向请求时,对所述 UE进 行重定向。
这样在指示所述基站取消禁止所述 UE 进行重定向时, 无需得建立指示消 息, 可以采用初始上下文请求消息或下行非接入层 NAS传输消息指示所述第一 基站取消禁止对所述 UE 进行重定向, 或者指示允许所述第一基站接收到所述 UE发送的重定向请求时, 对所述 UE进行重定向。 例如, 所述初始上下文请求 消息或所述下行非接入层 NAS传输消息携带所述第二列表, 或携带内容为空的 第一列表。
当所述基站接收到携带有所述第二列表或内容为空的第一列表的初始上下 文请求消息或下行非接入层 NAS传输消息,就取消禁止对所述 UE进行重定向, 当接收到 UE的重定向请求时, 就可以控制 UE进行重定向。
作为一种可选的实施方式, 本实施例中的初始上下文请求消息或下行非接 程中通过 S1口发送的初始上下文请求消息或下行非接入层 NAS传输消息。
在上述过程中会把所述初始上下文请求消息或所述下行非接入层 NAS传输
消息发送至所述基站。 所述基站接收到所述初始上下文请求消息或所述下行非 接入层 NAS传输消息就会取消禁止对所述 UE进行重定向。上述 TAU过程和服 务请求过程以及 TAU流程和服务请求过程中 S1 口的初始上下文请求消息, 都 是现有的, 此处不作详细说明。 这样保持所述 UE业务连续性的同时, 还可以节 约网络资源。
作为一种可选的实施方式, 本实施例中第一设备具体可以是 MME, 第二设 备具体可以是 UE的服务基站。
上述技术方案中, 在上面实施例的基础上增加了当第一定时器超时时, 第 一设备向所述第一基站发送第二消息, 所述第二消息用于指示所述第一基站取 消禁止对所述 UE进行重定向,或者指示允许所述第一基站接收到所述 UE发送 的重定向请求时, 对所述 UE进行重定向。 这样可以实现只禁止 UE—段时间不 能进行同系统和 /或异系统的重定向, 从而不影响 UE的业务, 同时可以减少 UE 重定向失败率, 并进而提高用户体验。
图 3 是本发明实施例提供的另一种重定向处理方法的流程示意图, 如图 3 所示, 包括如下步骤。
301、 第一设备累计所述 UE重定向失败的次数; 其中, 若所述第一设备接 收到所述第一基站发送的 S1译放请求消息后的一段时间内没有接收到由服务通 用分组无线服务技术支撑节点 (Serving General Packet Radio Service Support Node, SGSN )或第二基站发送的所述 UE的上下文请求消息, 所述第一设备将 所述 UE重定向失败的次数增加 1。
其中, 所述第一基站为所述 UE的服务基站, 所述 S1译放请求消息包含的 原因值为重定向, 所述 SGSN所属的系统与所述第一基站所属的系统不同, 所 述第二基站所属的系统与所述第一基站所属的系统相同。
例如, 当 UE 的异系统的重定向成功后, 该异系统的重定向的目标系统的 SGSN会向第一设备发送所述 UE的上下文请求消息, 当 UE的同系统的重定向 成功后,该同系统的重定向的目标小区的基站会向第一设备发送所述 UE的上下 文请求消息以获取到第一设备保存的所述 UE的相关信息。当第一设备没有接收 到所述 UE的上下文请求消息, 就确定所述 UE的重定向失败, 步骤 301将所述 UE的重定向失败次数加 1。

步骤 303具体可以采用上面实施例描述的步骤 202的实施方式。
作为一种可选的实施方式, 该方法还可以包括: 如果所述第一设备指示所 述第一基站取消禁止对所述 UE进行重定向,或者指示允许所述第一基站接收到 所述 UE发送的重定向请求时, 对所述 UE进行重定向, 所述第一设备将累计的 所述 UE重定向失败的次数清零。 也就是, 执行完步骤 303时, 所述第一设备将 累计的所述 UE重定向失败的次数清零。
作为一种可选的实施方式, 本实施例中第一设备具体可以是 MME。
上述技术方案中, 上面实施例的基石出上增加了, 第一设备累计所述 UE重定 向失败的次数, 当 UE重定向失败的次数超过第一阈值时, 第一设备通过 S1接 口向第一基站发送第一消息,所述第一消息用于指示所述基站禁止对所述 UE进 行同系统和 /或异系统的重定向。 这样第一设备可以精确控制在何种情况下通过 S1接口向第一基站发送第一消息指示所述基站禁止对所述 UE进行同系统和 /或 异系统的重定向, 同时可以减少 UE重定向失败率, 并进而提高用户体验。
图 4是本发明实施例提供的另一种重定向处理方法的流程示意图, 如图 4 所示, 包括如下步骤。
401、 第二设备通过 S1接口接收第一设备发送的第一消息, 所述第一消息 用于指示所述第二设备禁止对所述 UE进行同系统和 /或异系统的重定向; 其中, 所述第一消息是所述第一设备判断出所述 UE 的重定向失败次数超过第一阈值 时发送的。
例如, UE的重定向失败次数超过第一阈值时, 第一设备就会通过 S1接口 向第二设备发送第一消息, 以指示所述第二设备禁止对所述 UE进行同系统和 / 或异系统的重定向, 同样, 第二设备通过 S1接口接收到第一设备发送的第一消 息。
作为一种可选的实施方式, 上述第一消息具体可以是第一列表, 所述第一 列表包括: 系统标识, 所述系统标识对应的系统为所述第一设备指示所述第二 设备禁止所述 UE进行异系统的重定向的目标系统; 和 /或, 小区标识, 所述小 区标识对应的小区为所述第一设备指示所述第二设备禁止所述 UE 进行同系统 的重定向的目标小区。

作为一种可选的实施方式, 所述第一消息具体可以为初始上下文请求消息 或下行非接入层 NAS传输消息, 也就是说, 第二设备在所述初始上下文请求消 息或所述下行非接入层 NAS传输消息接收到指示所述第二设备禁止对所述 UE 进行同系统和 /或异系统的重定向。
步骤 401具体可以是第二设备通过 S1接口接收第一设备发送的所述初始上 下文请求消息或所述下行非接入层 NAS传输消息, 所述初始上下文请求消息或
所述下行非接入层 NAS传输消息指示所述第二设备禁止对所述 UE进行同系统 和 /或异系统的重定向。
这样在第二设备接收到第一设备发送的指示所述第二设备禁止所述 UE 进 行同系统和 /或异系统的重定向, 无需接收到新的消息, 可以在现有过程中接收 到初始上下文请求消息或下行非接入层 NAS传输消息, 接收到的初始上下文请 求消息或下行非接入层 NAS传输消息指示所述第二设备禁止对所述 UE进行同 系统和 /或异系统的重定向。 这样可以保证 UE业务的连续性, 并进而提高用户 体验。
该实施方式中, 上述初始上下文请求消息或所述下行非接入层 NAS传输消 送的初始上下文请求消息或下行非接入层 NAS传输消息。
在上述 TAU过程和服务请求过程中会接收到所述初始上下文请求消息或所 述下行非接入层 NAS传输消息。 上述 TAU过程和服务请求过程以及 TAU流程 和服务请求过程中 S1口的初始上下文请求消息, 都是现有的, 此处不作详细说 明。 这样保持所述 UE业务连续性的同时, 还可以节约网络资源。

402、所述第二设备根据所述第一消息禁止对 UE进行同系统和 /或异系统的 重定向。
可以理解的是, 第二设备具体根据第一消息的内容不同, 禁止对 UE进行不 同的同系统和 /或异系统的重定向。 如第一消息的内容为指示第二设备禁止异系
