Description

移动性管理方法及设备 技术领域 本发明实施例涉及通信技术, 尤其涉及一种移动性管理方法及设备。 背景技术
随着通信技术的发展,第三代合作伙伴组织( Third Generation Partnership Project, 简称 3GPP )对 3G长期演进型 ( Long Term Evolution, 简称 LTE ) 技术, 进行了研究与标准化工作, 以期待获得更高速度、 更大容量和更好的 用户性能。 在 LTE部署初期, LTE网络仅对热点地区部署, 而 2G/3G网络进 行全面覆盖。 在多种无线网络重叠或者相邻的区域, UE ( User Equipment , 用户设备)在 LTE网络与 2G/3G网络之间来回移动时, UE需要进行系统间 小区重选, 每一次系统间的小区重选都会引起 UE的位置更新过程, 从而更 新其在核心网中注册的位置信息,这会导致网络和空口增加大量的信令负载。
为了解决上述问题, 3GPP引入了空闲状态信令缩减 ( Idle State Signaling Reduction, 简称 ISR )机制。 在激活 ISR机制后, UE在已注册的覆盖区域移 动时, 即使跨制式, 也不需要进行位置更新。 同时, 如果网络需要寻呼 UE, 则在 UE在不同网络制式下注册的位置区内的小区对 UE进行寻呼。但是由于 UE只可能驻留在一种网络制式下,监听一个小区的寻呼消息, 现有技术中对 所有 UE注册的位置区都进行寻呼无疑造成了系统空口资源的浪费, 亟需提 出一种在混合网络制式下对 UE寻呼的优化方法。 发明内容

为使本发明实施例的目的、 技术方案和优点更加清楚, 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为本发明实施例提供的第一种移动性管理方法流程图。如图 1所示,
LTE 网络和 2G/3G 网络同时存在的应用场景。 2G 网络包括 GSM ( Global System of Mobile,全球移动通讯系统)网络和 TDMA ( Time Division Multiple Access, 时分多址 )网络等, 3G网络包括 WCDMA ( Wideband Code Division Multiple Access , 宽 带码分多 址 ) 网 络和 TD-SCDMA ( Time Division- Synchronous Code Division Multiple Access, 时分同步码分多址 ) 网 络等。 LTE网络中的网元具体包括 P-GW ( Packet Data Network Gateway, 分 组数据网络网关) 、 S-GW ( Serving Gateway, 服务网关) 、 MME ( Mobility Management Entity, 移动性管理实体)和 eNB ( evolved Node B, 演进型基 站)。 2G网络中的网元具体包括 P-GW、 S-GW、 SGSN ( Serving GPRS Support Node, GPRS业务支撑节点 )、 BTS ( Base Transceiver Station, 基站 )和 BSC ( Base Station Controller, 基站控制器)。 3G网络中的网元具体包括 P-GW 、 S-GW, SGSN, Node B (基站)和 RNC ( Radio Network Controller, 无线网 络控制器)。 为了描述方便, 以下实施例均以 LTE网络和 2G/3G网络同时存 在的应用场景进行说明, 但本发明并不以此为限。 本实施例提供的移动性管理方法, 具体包括:
步骤 111、 统一无线控制器 SRC接收至少一个第一网络设备对用户设备 UE发送的寻呼消息, 其中, 所述寻呼消息中携带有用以指示所述 UE的用户 标识;
步骤 112、 所述 SRC根据所述寻呼消息中的用户标识确定所述 UE的寻 呼管理上下文, 其中, 所述 UE的寻呼管理上下文中记录有网络制式信息, 所述网络制式信息用以指示所述 UE转入空闲态时所驻留的网络制式或者所 述 UE转入空闲态后重定向到的网络制式;
步骤 113、 所述 SRC根据所述寻呼消息和所述 UE的寻呼管理上下文确 定寻呼范围, 向所述寻呼范围中的小区发起对所述 UE的寻呼。
具体地, SRC ( Single Radio Controller, 统一无线控制器)为新增设的网 元, SRC可以统一管理同一区域内不同网络制式的第二网络设备, 在该区域 内, SRC管理的同一网络制式下的第二网络设备的数量可以为一个或多个, 每个第二网络设备都有其对应的第一网络设备, 且每个第一网络设备或第二 网络设备通过各自的接口与 SRC 交互。 在 LTE 网络中, 第一网络设备为 MME, 第二网络设备为 eNB, 在 2G网络中, 第一网络设备为 SGSN, 第二 网络设备为 BSC, 在 3G网络中, 第一网络设备为 SGSN, 第二网络设备为 RNC。在实际实现过程中, SRC也可以集成在 BSC和 /或 RNC中,或者, SRC、 BSC和 RNC三者可以集成在一起。
在一种网络架构下, SRC可以设置在第一网络设备与第二网络设备之间,
SRC上设置有与该区域内不同网络制式中的第二网络设备的接口以及与不同 网络制式中的第一网络设备的接口。 如图 2 所示, 该网络架构下设置有 P-GW11 , S-GW12, SGSN13 , MME14、 SRC15、 BSC16、 RNC17、 BTS18、 Node B19和 eNB21 , SRC 15与 SGSN13的接口为 Gb/Iu, SRC 15与 MME14 的接口为 SI , —个 SRC15上的 Gb或 Iu或 SI接口的数量均可以为一个或多 个。
在另一种网络架构下, SRC 并不直接与第一网络设备连接, SRC上可 以设置有与该区域内不同网络制式中的第二网络设备的接口, 第二网络设备 可以将第一网络设备发送的信令转发给 SRC。 如图 3所示, 该网络架构下设 置有 P-GW11、 S-GW12, SGSN13 , MME14、 SRC15、 BSC16、 RNC17、 BTS18、 Node B 19和 eNB21 , SGSN13与 BSC16的接口为 Gb, SGSN13与 RNC17的 接口为 Iu, MME14与 eNB21的接口为 S1 , SRC15与 BSC16、RNC17和 eNB21 直接交互, 与一个 SRC15连接的与 BSC16、 RNC17或 eNB21的数量均可以 为一个或多个。 在实际应用过程中, 用户标识用以指示 UE, 网络中各网元之 间的交互信息中均可以携带有该用户标识或交互信息的会话用用户标识绑 定,以指示网络服务的对象。用户标识具体可以为永久标识 IMSI( International Mobile Subscriber Identification, 国际移动用户识别码)或临时标识 S-TMSI 或 P-TMSI等。 需要说明的是, UE处于连接态时, SRC在 3G网络制式的 Iu 接口, 可以在信令中收到 UE的永久标识 IMSI; 在 2G网络制式的 Gb接口, 第一网络设备可以被配置为在 Gb接口信令中发送 UE的永久标识 IMSI , SRC 也可以获得 UE的 IMSI; 在 LTE网络制式下, 第一网络设备在 S 1接口不向 接入网发送 UE的 IMSI。 则在 UE转入空闲态前, 处于 2G/3G网络制式的 UE, UE的寻呼管理上下文中记录有永久标识 IMSI; 处于 LTE 网络制式的 UE, UE的寻呼管理上下文中记录的可能只有临时标识 S-TMSI,在从本 SRC 控制的 2G/3G网络制式下的小区切换到 LTE网络制式下的小区然后转入空闲 态的 UE, SRC也可识别出该 UE的永久标识 IMSI, 并记录在 UE的寻呼管 理上下文中。 由于在 2G/3G/LTE网络制式下, 第一网络设备发往 SRC的寻 呼消息中, 携带 UE的永久标识 IMSI和临时标识 P-TMSI和 S-TMSI, SRC 收到不同网络制式的接口发来的对转入空闲态前处于 2G/3G网络制式下的对 UE的寻呼消息, 都可以根据 UE的永久标识 IMSI找到 UE的寻呼管理上下 文。如果 UE的寻呼管理上下文中没有记录 UE的 IMSI(转空闲态前处于 LTE 网络制式时) , 则 SRC只有从 LTE网络制式的与第一网络设备的接口收到 UE的寻呼消息, 才能确定该 UE的寻呼管理上下文。 如果 UE的寻呼管理上 下文中记录 UE的 IMSI (从本 SRC的 2G/3G网络制式下的小区切换到 LTE 网络制式下的小区, 或 LTE网络制式的与第一网络设备接口在连接态的信令 中携带有 IMSI ) , 则 SRC收到不同网络制式的接口发来的对转入空闲态前 处于 2G/3G网络制式下的 UE的寻呼消息, 都可以根据 UE的永久标识 IMSI 找到 UE的寻呼管理上下文。 UE的寻呼管理上下文中还记录有网络制式信息, 用以指示 UE转入空闲态时所驻留的网络制式或者 UE转入空闲态后重定向到 的网络制式, UE 的寻呼管理上下文中还记录有小区标识, 以指示小区。 若 SRC在下发的消息中未指示网络制式和频点和 /或小区, UE的寻呼管理上下 文中所记录的 UE驻留的网络制式的小区为 UE转入空闲态之前最后一次连接 态时所在的小区,若 SRC在下发的消息中指示网络制式和频点和 /或小区,且 UE的 ISR激活, UE转入空闲态后会到指示的网络制式和频点和 /或小区中, 且不发起位置更新,则 UE的寻呼管理上下文中所记录的 UE驻留的网络制式 的小区为该指示的网络制式和频点和 /或小区。
UE转入空闲态后, 该 UE的下行数据到达 P-GW, P-GW将下行数据发 送给 S-GW, S-GW会分别向 MME和 SGSN发送下行数据通知消息, 图 2所 示的网络架构下, MME和 SGSN分别向 SRC发送寻呼消息; 或者图 3所示 的网络架构下, MME向 eNB发送寻呼消息, SGSN向 BSC/RNC发送寻呼消 息, eNB/BSC/RNC并不直接寻呼, 而是将寻呼消息转发给 SRC。 SRC可以 从不同的网络制式的一个或多个接口接收到寻呼消息, SRC根据接收到的寻 呼消息的网络制式和 UE的寻呼管理上下文中所记录的网络制式确定寻呼范 围, 该寻呼范围包括 UE的寻呼管理上下文中所记录的第一网络制式中的该 SRC覆盖范围内的小区的一个或多个。
SRC才艮据寻呼消息和 UE的寻呼管理上下文确定寻呼范围的实现方式可 以有多种:
在第一种实现方式中, SRC可能在较短的时间内从不同的网络制式的一 个或多个接口接收到寻呼消息, 其中一种网络制式为 UE的寻呼管理上下文 中所记录的第一网络制式, 则可以首先在该第一网络制式中对 UE进行寻呼。 寻呼范围可以为 UE寻呼管理上下文中记录的小区或该小区及其周边小区。
SRC还可以预先对 UE在过去的一段预设时间内所驻留过的网络制式及 小区进行记录, 以形成该 UE的历史记录, 则该寻呼范围可以为 SRC可以根 据 UE历史记录确定第一网络制式下的小区。 SRC还可以根据运营商策略确 定第一网络制式下的小区, 运营商策略具体可以为运营商预先设置的策略, 例如,当该 UE的寻呼管理上下文中所记录的 UE转空闲态前驻留的小区为火 车站, 则认为用户可能进入火车等交通工具, 并沿着某条路线移动, 则寻呼 范围可以为该路线上的小区。
第一网络设备发送的寻呼消息中携带有位置区标识, 位置区标识用以指 示 UE已经注册的位置区,例如在 2G/3G网络中, SGSN注册 RAI( Routing Area ID, 路由区标识 )或在 LTE网络中, MME注册 TAI list ( Tracking Area ID, 跟踪区标识列表) 。 该位置区标识可以为路由区标识或跟踪区标识列表。 则 该寻呼范围可以为 SRC根据从该第一网络制式的接口接收到的寻呼消息中携 带的位置区标识所指示的位置区内确定的小区。
在第二种实现方式中, SRC可能首先从某个网络制式的一个或多个接口 接收到寻呼消息, 例如, 从第一网络制式的接口接收到第一寻呼消息, 第一 网络制式与 UE的寻呼管理上下文中所记录的网络制式相同, 则 SRC不用等 待其他寻呼消息的到来,就可以根据 UE的寻呼管理上下文、 UE的历史记录、 运营商策略和该第一寻呼消息中携带的位置区标识中的一种或几种, 确定寻 呼范围。
若该第一网络制式与 UE的寻呼管理上下文中所记录的网络制式不相同, SRC可以先在第一网络制式中准备寻呼资源, 例如在寻呼队列中排队。 当寻 呼还未在空口发送时, SRC从与 UE的寻呼管理上下文中所记录的网络制式 相同的第二网络制式的接口接收到对该 UE的寻呼消息, 则 SRC在第一网络 制式中释放对 UE的寻呼资源, 例如把 UE从寻呼队列中删除, 并根据 UE的 寻呼管理上下文、 UE的历史记录、运营商策略和该第一寻呼消息中携带的位 置区标识中的一种或几种, 确定寻呼范围。
若该第一网络制式与 UE的寻呼管理上下文中所记录的网络制式不相同, SRC还可以启动定时器 S, 等待从与 UE的寻呼管理上下文中所记录的网络 制式相同的第二网络制式的接口发来的对 UE的寻呼消息。 如果定时器 S超 时前,收到从第二网络制式的接口发来的对 UE的寻呼消息,则根据 UE的寻 呼管理上下文、 UE的历史记录、运营商策略和该第一寻呼消息中携带的位置 区标识中的一种或几种, 确定寻呼范围。
在第三种实现方式中, 第一网络设备发送的寻呼消息中携带有激活指示 信息, 该激活指示信息用以指示 UE的空闲状态信令缩减 ISR是否激活, 若 SRC接收一个寻呼消息中携带有该激活指示信息,且该激活指示信息指示 UE 的 ISR激活, 则 SRC不需要等待所有的寻呼消息都接收到, 就可以根据 UE 的寻呼管理上下文、 UE的历史记录、运营商策略或该第一寻呼消息中携带的 位置区标识中的一种或几种, 确定寻呼范围。
SRC向寻呼范围中的小区发起对该 UE的寻呼的具体过程可以为: SRC 向寻呼范围中的小区对应的第二网络设备发送寻呼消息, 第二网络设备再在 相应的小区中对 UE进行寻呼。
值得注意的是, 当 SRC总共接收到的寻呼消息的数量为多个时, 在上述 SRC首先从与 UE的寻呼管理上下文中所记录的网络制式相同的网络制式的 接口中接收到寻呼消息或者接收到的寻呼消息中携带有指示 UE的 ISR激活 的指示消息的实现方式中, SRC可以无需等待全部的寻呼消息都接收到后再 执行步骤 112, 即步骤 111和步骤 112并不具有必然的时序关系。
本实施例提供的移动性管理方法, SRC接收至少一个第一网络设备发送 的寻呼消息, 其中, 寻呼消息中携带有用以指示用户设备 UE的用户标识, 根据寻呼消息中的用户标识确定 UE的寻呼管理上下文, 其中, UE的寻呼管 理上下文中记录有网络制式信息, 网络制式信息用以指示 UE转入空闲态时 所驻留的网络制式或者 UE转入空闲态后重定向到的网络制式, 才艮据寻呼消 息和 UE 的寻呼管理上下文确定寻呼范围, 向寻呼范围中的小区发起对 UE 的寻呼。 SRC可以从不同网络制式下的接口接收寻呼消息, 根据寻呼消息和 UE的寻呼管理上下文确定 UE的寻呼管理上下文中记录的网络制式下的寻呼 范围, 实现对寻呼过程的优化, 尤其是避免了 UE的 ISR激活时, 不同网络 制式下的第一网络设备对 UE注册的位置区中的所有小区都进行寻呼而造成 的资源浪费, 提高了移动性管理效果。
图 4为本发明实施例提供的第二种移动性管理方法流程图。如图 4所示, 在本实施例中, 所述 SRC接收到的所述寻呼消息中包括第一寻呼消息;
步骤 113 , 所述 SRC根据所述寻呼消息和所述 UE的寻呼管理上下文确 定寻呼范围, 具体可以包括:
所述 SRC若首先从与所述网络制式信息所指示的网络制式相同的第一网 络制式的接口接收到所述第一寻呼消息, 则根据所述 UE的历史记录或预设 策略,或者, 当所述 UE的寻呼管理上下文中还记录有用以指示所述 UE转入 空闲态时所驻留的小区标识或者所述 UE转入空闲态后重定向到的小区标识 时, 根据所述小区标识, 在所述第一网络制式下确定所述寻呼范围。
在第一种实现方式中,具体地, SRC首先从第一网络制式的接口接收第 一寻呼消息, 该第一网络制式为 UE的寻呼管理上下文中记录的网络制式, SRC可以根据 UE的寻呼管理上下文、 UE的历史记录和预设策略中的一种或 几种在第一网络制式下确定寻呼范围。
在本实施例中, 所述寻呼消息中携带有位置区标识; 所述 SRC向所述寻 呼范围中的小区发起对所述 UE的寻呼之后, 所述方法还包括:
步骤 114、所述 SRC若在第一预设时间内未接收到所述 UE的寻呼响应, 则根据所述第一寻呼消息中的位置区标识确定所述 UE在所述第一网络制式 下注册的所有小区;
步骤 115、 所述 SRC向所述 UE在所述第一网络制式下注册的所有小区 发起对所述 UE的寻呼。
具体地, 若第一网络制式为 2G/3G网络, 则第一寻呼消息中的位置区标 识为 RAI, 若第一网络制式为 LTE网络, 则位置区标识为 TAI list。
当在第一网络制式下的寻呼范围内未寻呼到 UE时, 可以进一步扩大该 寻呼范围, 则可以该第一寻呼消息中的位置区标识确定该 UE在第一网络制 式下注册的所有小区, 并再次发起对 UE的寻呼。
在本实施例中,所述 SRC接收到的所述寻呼消息中还包括第二寻呼消息, 所述第一寻呼消息所属的第一网络制式与所述第二寻呼消息所属的第二网络 制式不同;
步骤 115, 所述 SRC向所述 UE在所述第一网络制式下注册的所有小区 发起对所述 UE的寻呼之后, 所述方法还包括:
步骤 116、所述 SRC若在第二预设时间内未接收到所述 UE的寻呼响应, 则根据所述第一寻呼消息中的位置区标识和所述第二寻呼消息中的位置区标 识确定所述 UE在所述第 ―网络制式和所述第二网络制式下注册的所有小区; 步骤 117、 所述 SRC向所述 UE在所述第一网络制式和所述第二网络制 式下注册的所有小区发起对所述 UE的寻呼。
具体地, SRC在接收到第一寻呼消息后, 从与第一网络制式不同的第二 网络制式的接口接收到第二寻呼消息。
当在第一网络指示下注册的所有小区中都为寻呼到该 UE时, 可以再进 一步扩大寻呼范围。 根据第一寻呼消息中的位置区标识确定该 UE在第一网 络制式下注册的所有小区, 根据第二寻呼消息中的位置区标识确定该 UE在 第二网络制式下注册的所有小区, 并再次发起对 UE的寻呼。
通过对寻呼范围逐渐扩大, 可以避免在一开始就在所有网络制式下的小 区对 UE进行寻呼所造成的空口资源的浪费。
在实际应用过程中,如果 SRC先收到某个网络制式,例如网络制式 A的 第一网络设备在该网络制式的接口向 SRC发送 UE的寻呼消息,则 SRC根据 UE的用户标识查找到 UE的寻呼管理上下文。 如果 UE寻呼管理上下文中记 录的制式是 A, 则 SRC先在网络制式 A中对 UE进行寻呼。 寻呼范围可以是 UE寻呼管理上下文中记录的小区或该小区及其周边小区, 也可以是 SRC根 据 UE历史记录和 /或运营商策略确定的小区。 在寻呼的同时启动定时器 M, 如果在定时器 M超时前 SRC未收到 UE的寻呼响应, SRC收到不同于网络制 式 A的网络制式 Y的接口发来的对该 UE的寻呼消息,并不在网络制式 Y下 对 UE的寻呼, 直到定时器 M超时, 仍未收到 UE的寻呼响应 , SRC再在该 网络制式 Y的小区中对 UE寻呼,本次寻呼范围还可包含网络制式 A的小区。
在本实施例中, 所述寻呼消息中携带有位置区标识, 所述寻呼消息中携 带有位置区标识, 所述 SRC接收到的所述寻呼消息中包括第一寻呼消息和第 二寻呼消息,所述 UE的寻呼管理上下文中还记录有用以指示所述 UE转入空 闲态时所驻留的小区标识或者所述 UE转入空闲态后重定向到的小区标识; 步骤 113 , 所述 SRC根据所述寻呼消息和所述 UE的寻呼管理上下文确 定寻呼范围, 具体可以包括:
所述 SRC若首先从第一网络制式的第一接口接收到所述第一寻呼消息, 若所述第一网络制式与所述网络制式信息所指示的网络制式相同, 且所述第 一接口与所述小区标识所指示的小区对应的第二接口不同, 则根据所述第 ― 寻呼消息中的位置区标识确定所述寻呼范围, 并根据所述寻呼范围准备寻呼 资源; 若在通过所述寻呼资源进行寻呼之前, 从所述第一网络制式的所述第 二接口接收到所述第二寻呼消息, 则释放所述寻呼资源, 根据所述小区标识、 所述 UE的历史记录、 预设策略和所述第二寻呼消息中的位置区标识中的一 个或多个,在所述第二接口对应的第二网络设备的小区中确定所述寻呼范围; 或者,
所述 SRC若首先从第一网络制式的第一接口接收到所述第一寻呼消息, 若所述第一网络制式与所述网络制式信息所指示的网络制式相同, 且所述第 一接口与所述小区标识所指示的小区对应的第二接口不同, 若在第三预设时 间内从所述第一网络制式的所述第二接口接收到所述第二寻呼消息, 则根据 所述小区标识、 所述 UE的历史记录、 预设策略和所述第二寻呼消息中的位 置区标识的一个或多个, 在所述第二接口对应的第二网络设备的小区中确定 所述寻呼范围; 或者,
所述 SRC若首先从第一网络制式的第一接口接收到所述第一寻呼消息, 若所述第一网络制式与所述网络制式信息所指示的网络制式相同, 且所述第 一接口与所述小区标识所指示的小区对应的第二接口相同, 则根据所述第 ― 寻呼消息中的位置区标识确定所述寻呼范围, 并才艮据所述寻呼范围寻呼 UE; 若在第四预设时间内, 从所述第 ―网络制式的第三接口接收到所述第二寻呼 消息, 且所述第三接口与所述第二接口不同, 则在第四预设时间结束后, 在 未接收到所述 UE的寻呼响应时, 根据所述小区标识、 所述 UE的历史记录、 预设策略和所述第一寻呼消息、 第二寻呼消息中的位置区标识中的一个或多 个, 在所述第一接口和第二接口对应的第二网络设备的小区中确定所述寻呼 范围。
具体地, 在第一种实现方式中, 当第一网络设备从 UE的寻呼管理上下 文中所记录的第一网络制式的接口发来对 UE的寻呼消息, 但该接口不属于 UE寻呼管理上下文中记录的小区所在的第二网络设备, 则 SRC确定的寻呼 范围可以为 SRC根据从该第一网络制式的接口接收到的寻呼消息中携带的位 置区标识所指示的位置区内确定的小区。
如果 SRC从同一网络制式的不同接口收到对同一个 UE的寻呼消息, 在 根据 UE寻呼管理上下文、 UE的历史记录、 运营商策略和 UE已经注册的位 置区标识中的一种或几种确定寻呼范围后, SRC首先向此次确定的寻呼范围 包含小区所属的第二网络设备发送寻呼。
当在该寻呼范围内没有寻呼到 UE时, 可以扩大寻呼范围, 其具体实现 过程可以参照图 4所示实施例, 在此不再赘述。
图 5为本发明实施例提供的第三种移动性管理方法流程图。如图 5所示, 在本实施例中, 所述寻呼消息中携带有位置区标识, 所述 SRC接收到的所述 寻呼消息中包括第一寻呼消息和第二寻呼消息;

所述 SRC若首先从与所述网络制式信息所指示的网络制式不同的第一网 络制式的接口接收到所述第一寻呼消息, 若在第三预设时间内从所述网络制 式信息所指示的网络制式相同的第二网络制式的接口接收到所述第二寻呼消 息, 则根据所述 UE的历史记录、 预设策略和所述第二寻呼消息中的位置区 标识中的一个或多个, 在所述第二网络制式下确定所述寻呼范围, 或者, 当 所述 UE的寻呼管理上下文中还记录有用以指示所述 UE转入空闲态时所驻留 的小区标识或者所述 UE转入空闲态后重定向到的小区标识时, 才艮据所述小 区标识在所述第二网络制式下确定所述寻呼范围。
在第二种实现方式中, 具体地, 若 SRC首先从第一网络制式的接口接收 到寻呼消息, 该第一网络制式与 UE的寻呼管理上下文中所记录的网络制式 不相同, SRC可以先在第一网络制式中准备寻呼资源, 例如在寻呼队列中排 队。 当寻呼还未在空口发送时, SRC从与 UE的寻呼管理上下文中所记录的 网络制式相同的第二网络制式的接口接收到对该 UE的寻呼消息, 则 SRC在 第一网络制式中释放对 UE的寻呼资源,例如把 UE从寻呼队列中删除,并根 据 UE的寻呼管理上下文、 UE的历史记录、 运营商策略和该第一寻呼消息中 携带的位置区标识中的一种或几种, 确定寻呼范围。
或者, 若 SRC首先从第一网络制式的接口接收到寻呼消息, 该第一网络 制式该第一网络制式与 UE的寻呼管理上下文中所记录的网络制式不相同, SRC在第一网络制式的小区中寻呼 UE前, SRC还可以启动定时器 S, 等待 从与 UE的寻呼管理上下文中所记录的网络制式相同的第二网络制式的接口 发来的对 UE的寻呼消息。 如果定时器 S超时前, 收到从第二网络制式的接 口发来的对 UE的寻呼消息,则根据 UE的寻呼管理上下文、 UE的历史记录、 运营商策略和该第一寻呼消息中携带的位置区标识中的一种或几种, 确定寻 呼范围。

在第三种实现方式中,若 SRC接收一个寻呼消息中携带有 ISR激活指示 信息, 该激活指示信息指示 UE的 ISR是否激活, 则 SRC还可以根据该指示 及 UE的寻呼管理上下文、 UE的历史记录、 运营商策略或该第一寻呼消息中 携带的位置区标识中的一种或几种, 确定寻呼范围。 具体地, 在 UE 的 ISR 激活时, 若 SRC首先从第一网络制式的接口接收到寻呼消息, 该第一网络制 式与 UE的寻呼管理上下文中所记录的网络制式不相同, SRC在第一网络制 式的小区中寻呼 UE前, SRC启动定时器 S, 等待从与 UE的寻呼管理上下文 中所记录的网络制式相同的第二网络制式的接口发来的对 UE的寻呼消息。 如果定时器 S超时前, 收到从第二网络制式的接口发来的对 UE的寻呼消息, 则根据 UE的寻呼管理上下文、 UE的历史记录、 运营商策略和该第一寻呼消 息中携带的位置区标识中的一种或几种, 确定寻呼范围。 若 SRC首先从第一 网络制式的接口接收到寻呼消息, 该第一网络制式与 UE的寻呼管理上下文 中所记录的网络制式不相同, SRC可以先在第一网络制式中准备寻呼资源, 例如在寻呼队列中排队。 当寻呼还未在空口发送时, SRC从与 UE的寻呼管 理上下文中所记录的网络制式相同的第二网络制式的接口接收到对该 UE的 寻呼消息, 则 SRC在第一网络制式中释放对 UE的寻呼资源, 例如把 UE从 寻呼队列中删除, 并根据 UE的寻呼管理上下文、 UE的历史记录、 运营商策 略和该第一寻呼消息中携带的位置区标识中的一种或几种, 确定寻呼范围。 在 UE的 ISR未激活时,若 SRC首先从第一网络制式的接口接收到寻呼消息, 该第一网络制式与 UE 的寻呼管理上下文中所记录的网络制式不相同, SRC 不用等待, 直接根据第一寻呼消息中位置区标识在第一网络制式下确定寻呼 范围。
在本实施例中, 步骤 113 , 所述 SRC向所述寻呼范围中的小区发起对所 述 UE的寻呼之后, 所述方法还包括:
步骤 134、所述 SRC若在第一预设时间内未接收到所述 UE的寻呼响应, 则根据所述第一寻呼消息中的位置区标识确定所述 UE在所述第一网络制式 下注册的所有小区;
步骤 135、 所述 SRC向所述 UE在所述第一网络制式下注册的所有小区 发起对所述 UE的寻呼。
在本实施例中, 所述第一寻呼消息所属的第一网络制式与所述第二寻呼 消息所属的第二网络制式不同;

图 9为本发明实施例提供的第五种移动性管理方法流程图。如图 9所示, 在本实施例中, 步骤 111 , 所述 SRC接收至少一个第一网络设备对用户设备 UE发送的寻呼消息之前, 所述方法还可以包括:
步骤 101、 所述 SRC记录所述 UE处于连接态时所在的网络制式下的位 置信息, 形成所述 UE的寻呼管理上下文。
具体地, UE处于连接态时, UE会与 SRC或者通过第二网络设备与 SRC 进行交互, 则 SRC可以获知 UE所在的网络制式和小区。 SRC对 UE处于连 接态时所在网络制式的位置信息进行记录, 形成 UE的寻呼管理上下文, 该 位置信息具体可以为小区标识或者位置区标识或者其他可以指示 UE的位置 的信息。 当 UE发起位置更新时, SRC也根据 UE的位置更新对该寻呼管理 上下文进行更新。 UE的寻呼管理上下文可以在 UE处于连接态时的某个时间点生成或更新 记录, 也可以在该 UE转为空闲态的处理流程中生成或更新记录。
在本实施例中, 步骤 111 , 所述 SRC接收至少一个第一网络设备对用户 设备 UE发送的寻呼消息之前, 所述方法还可以包括:
步骤 102、 所述 SRC接收第二网络设备发送的检测到 UE去激活消息, 向所述第一网络设备发送 UE上下文释放请求消息;
步骤 103、 所述 SRC接收所述第一网络设备发送的 UE上下文释放命令 消息, 向所述第二网络设备发送无线资源控制 RRC上下文释放指示消息, 其 中, 所述 RRC上下文释放指示消息中携带有网络制式指示信息和 /或频点指 示信息;
步骤 104、 所述 SRC接收所述第二网络设备发送的 UE上下文释放完成 指示消息, 向所述第一网络设备发送 UE上下文释放完成消息。
具体地, 在图 2所示的网络架构下, UE转入空闲态的处理流程中, 第二 网络设备通过 SRC与第一网络设备进行通信。 SRC在向第二网络设备发送的 RRC上下文释放指示消息中可以携带网络制式指示信息和 /或频点指示信息。
SRC或者 SRC与第二网络设备配合, 根据连接态 UE所处位置的其他网络制 式的覆盖情况, 以及网络资源状况, 为该 UE确定一个网络制式的一个频点, 希望 UE可以在空闲态时驻留在 SRC所指示的网络制式的频点。
第二网络设备在接收到 SRC发送的 RRC上下文释放指示消息后,向 UE 发送 RRC连接释放消息, 该 RRC连接释放消息中携带有该网络制式指示信 息和 /或频点指示信息。 UE重选到该指示的网络制式和频点, 若 UE的 ISR 未激活, UE在 SRC的控制下的该网络制式的小区发起位置更新, SRC可以 根据 UE发起的位置更新记录或更新该 UE的寻呼管理上下文。 若 UE的 ISR 激活,且 UE重定向的小区位于该 UE注册的另一个网络制式的位置区内,则 UE没有在 SRC的控制下的小区内发起位置更新。 则 SRC可以根据指示 UE 的网络制式指示信息和频点指示信息对 UE的寻呼管理上下文进行更新。
SRC通过第二网络设备发给 UE的 RRC连接释放指示消息中带有网络制 式指示信息和 /或频点指示信息, SRC在 UE寻呼管理上下文中记录上述指示 网络制式指示信息和 /或频点指示信息对应的网络制式和小区。 可在 UE转入 空闲态时进行对应和记录, 也可以在进行对 UE寻呼时进行对应。 如果两个 接口都收到第一网络设备发来的寻呼消息,可以是两种网络制式都在记录(或 对应) 的小区或小区及周边小区寻呼。 如 UE转入空闲态是第一网络制式, 重定向是第二网络制式, 则也可以在第一网络制式和第二网络制式的接口收 到寻呼消息后, 第一轮就在在转入空闲态的第一网络制式的小区及其位置对 应的第二网络制式的小区都进行寻呼。显然, UE在连接态发生的任何网络制 式和小区的改变, SRC都进行记录。
步骤 105、所述 SRC根据所述网络制式指示信息和 /或所述频点指示信息 对所述 UE的寻呼管理上下文进行更新。
图 10为本发明实施例提供的第六种移动性管理方法流程图。 如图 10所 示, 在本实施例中, 在如图 3所示的网络架构下, UE转为空闲态的处理流程 还可以为,在步骤 111 ,所述 SRC接收至少一个第一网络设备对用户设备 UE 发送的寻呼消息之前, 包括如下步骤:
步骤 106、 所述 SRC接收第二网络设备发送的 UE连接释放请求消息; 步骤 107、 所述 SRC向所述第二网络设备发送 UE连接释放响应消息, 其中, 所述 UE连接释放响应消息中携带有网络制式指示信息和 /或频点指示 信息;

值得注意的是, 图 7和图 8所示实施例以 UE空闲态时驻留在 LTE网络 时为例对 UE的寻呼过程进行说明, UE空闲态时驻留在 2G/3G网络时对 UE 的寻呼过程类似。 图 11和图 12所示实施例以 UE转入空闲态之前在 LTE网 络为例对 UE转入空闲态的处理流程进行说明, UE转入空闲态之前在 2G网 络中的转入空闲态处理流程类似, 只需要将图 11和图 12 中的 eNB替换为 BSC即可, UE转入空闲态之前在 3G网络中的转入空闲态处理流程也类似, 只需要将图 11和图 12中的 eNB替换为 RNC即可, 具体实现过程在此不再 赘述。
图 13 为本发明实施例提供的第一种统一无线控制器结构示意图。 如图
13所示, 本实施例提供的统一无线控制器 15具体可以实现本发明任意实施 例提供的移动性管理方法的各个步骤, 具体实现过程在此不再赘述。 本实施 例提供的统一无线控制器 15, 具体包括:
接收单元 31 , 用于接收至少一个第一网络设备对用户设备 UE发送的寻 呼消息, 其中, 所述寻呼消息中携带有用以指示所述 UE的用户标识;
处理单元 32, 用于根据所述接收单元 32接收的寻呼消息中的用户标识 确定所述 UE的寻呼管理上下文,才艮据所述寻呼消息和所述 UE的寻呼管理上 下文确定寻呼范围, 其中, 所述 UE的寻呼管理上下文中记录有网络制式信 息, 所述网络制式信息用以指示所述 UE转入空闲态时所驻留的网络制式或 者所述 UE转入空闲态后重定向到的网络制式;
寻呼单元 33 , 用于向所述处理单元 32确定的寻呼范围中的小区发起对 所述 UE的寻呼。
具体地, SRC为新增设的网元, SRC可以统一管理同一区域内不同网络 制式的第二网络设备, 在该区域内, SRC管理的同一网络制式下的第二网络 设备的数量可以为一个或多个, 每个第二网络设备都有其对应的第一网络设 备, 且每个第一网络设备或第二网络设备通过各自的接口与 SRC 交互。 在 LTE网络中, 第一网络设备为 MME, 第二网络设备为 eNB, 在 2G网络中, 第一网络设备为 SGSN, 第二网络设备为 BSC, 在 3G网络中, 第一网络设备 为 SGSN,第二网络设备为 RNC。在实际实现过程中, SRC也可以集成在 BSC 和 /或 RNC中, 或者, SRC、 BSC和 RNC三者可以集成在一起。
在一种网络架构下, SRC可以设置在第一网络设备与第二网络设备之间, SRC上设置有与该区域内不同网络制式中的第二网络设备的接口以及与不同 网络制式中的第一网络设备的接口。在另一种网络架构下, SRC并不直接与 第一网络设备连接, SRC上可以设置有与该区域内不同网络制式中的第二网 络设备的接口, 第二网络设备可以将第一网络设备发送的信令转发给 SRC。
在实际应用过程中, 用户标识用以指示 UE, 网络中各网元之间的交互信 息中均可以携带有该用户标识或交互信息的会话用用户标识绑定, 以指示网 络服务的对象。 用户标识具体可以为永久标识 IMSI或临时标识 S-TMSI或 P-TMSI等。 需要说明的是, UE处于连接态时, SRC在 3G网络制式的 Iu接 口, 可以在信令中收到 UE的永久标识 IMSI; 在 2G网络制式的 Gb接口, 第 一网络设备可以被配置为在 Gb接口信令中发送 UE的永久标识 IMSI , SRC 也可以获得 UE的 IMSI; 在 LTE网络制式下, 第一网络设备在 S 1接口不向 接入网发送 UE的 IMSI。 则在 UE转入空闲态前, 处于 2G/3G网络制式的 UE, UE的寻呼管理上下文中记录有永久标识 IMSI; 处于 LTE 网络制式的 UE, UE的寻呼管理上下文中记录的可能只有临时标识 S-TMSI,在从本 SRC 控制的 2G/3G网络制式下的小区切换到 LTE网络制式下的小区然后转入空闲 态的 UE, SRC也可识别出该 UE的永久标识 IMSI, 并记录在 UE的寻呼管 理上下文中。 由于在 2G/3G/LTE网络制式下, 第一网络设备发往 SRC的寻 呼消息中, 携带 UE的永久标识 IMSI和临时标识 P-TMSI和 S-TMSI, SRC 收到不同网络制式的接口发来的对转入空闲态前处于 2G/3G网络制式下的对 UE的寻呼消息, 都可以根据 UE的永久标识 IMSI找到 UE的寻呼管理上下 文。如果 UE的寻呼管理上下文中没有记录 UE的 IMSI(转空闲态前处于 LTE 网络制式时) , 则 SRC只有从 LTE网络制式的与第一网络设备的接口收到 UE的寻呼消息, 才能确定该 UE的寻呼管理上下文。 如果 UE的寻呼管理上 下文中记录 UE的 IMSI (从本 SRC的 2G/3G网络制式下的小区切换到 LTE 网络制式下的小区, 或 LTE网络制式的与第一网络设备接口在连接态的信令 中携带有 IMSI ) , 则 SRC收到不同网络制式的接口发来的对转入空闲态前 处于 2G/3G网络制式下的 UE的寻呼消息, 都可以根据 UE的永久标识 IMSI 找到 UE的寻呼管理上下文。 UE的寻呼管理上下文中还记录有网络制式信息, 用以指示 UE转入空闲态时所驻留的网络制式或者 UE转入空闲态后重定向到 的网络制式, UE 的寻呼管理上下文中还记录有小区标识, 以指示小区。 若 SRC在下发的消息中未指示网络制式和频点和 /或小区, UE的寻呼管理上下 文中所记录的 UE驻留的网络制式的小区为 UE转入空闲态之前最后一次连接 态时所在的小区,若 SRC在下发的消息中指示网络制式和频点和 /或小区,且 UE的 ISR激活, UE转入空闲态后会到指示的网络制式和频点和 /或小区中, 且不发起位置更新,则 UE的寻呼管理上下文中所记录的 UE驻留的网络制式 的小区为该指示的网络制式和频点和 /或小区。
UE转入空闲态后, 该 UE的下行数据到达 P-GW, P-GW将下行数据发 送给 S-GW, S-GW会分别向 MME和 SGSN发送下行数据通知消息, MME 和 SGSN分别向 SRC发送寻呼消息;或者 MME向 eNB发送寻呼消息, SGSN 向 BSC/RNC发送寻呼消息, eNB/BSC/RNC并不直接寻呼, 而是将寻呼消息 转发给 SRC。 SRC可以从不同的网络制式的一个或多个接口接收到寻呼消息, SRC根据接收到的寻呼消息的网络制式和 UE的寻呼管理上下文中所记录的 网络制式确定寻呼范围, 该寻呼范围包括 UE的寻呼管理上下文中所记录的 第一网络制式中的该 SRC覆盖范围内的小区的一个或多个。
SRC才艮据寻呼消息和 UE的寻呼管理上下文确定寻呼范围的实现方式可 以有多种:
在第一种实现方式中, SRC可能在较短的时间内从不同的网络制式的一 个或多个接口接收到寻呼消息, 其中一种网络制式为 UE的寻呼管理上下文 中所记录的第一网络制式, 则可以首先在该第一网络制式中对 UE进行寻呼。 寻呼范围可以为 UE寻呼管理上下文中记录的小区或该小区及其周边小区。
SRC还可以预先对 UE在过去的一段预设时间内所驻留过的网络制式及 小区进行记录, 以形成该 UE的历史记录, 则该寻呼范围可以为 SRC可以根 据 UE历史记录确定第一网络制式下的小区。 SRC还可以根据运营商策略确 定第一网络制式下的小区, 运营商策略具体可以为运营商预先设置的策略, 例如,当该 UE的寻呼管理上下文中所记录的 UE转空闲态前驻留的小区为火 车站, 则认为用户可能进入火车等交通工具, 并沿着某条路线移动, 则寻呼 范围可以为该路线上的小区。
第一网络设备发送的寻呼消息中携带有位置区标识, 位置区标识用以指 示 UE已经注册的位置区 , 例如在 2G/3G网络中, SGSN注册 RAI或在 LTE 网络中, MME注册 TAI list。 该位置区标识可以为路由区标识或跟踪区标识 列表。 则该寻呼范围可以为 SRC根据从该第一网络制式的接口接收到的寻呼 消息中携带的位置区标识所指示的位置区内确定的小区。
在第二种实现方式中, SRC可能首先从某个网络制式的一个或多个接口 接收到寻呼消息, 例如, 从第一网络制式的接口接收到第一寻呼消息, 第一 网络制式与 UE的寻呼管理上下文中所记录的网络制式相同, 则 SRC不用等 待其他寻呼消息的到来,就可以根据 UE的寻呼管理上下文、 UE的历史记录、 运营商策略和该第一寻呼消息中携带的位置区标识中的一种或几种, 确定寻 呼范围。
若该第一网络制式与 UE的寻呼管理上下文中所记录的网络制式不相同,
SRC可以先在第一网络制式中准备寻呼资源, 例如在寻呼队列中排队。 当寻 呼还未在空口发送时, SRC从与 UE的寻呼管理上下文中所记录的网络制式 相同的第二网络制式的接口接收到对该 UE的寻呼消息, 则 SRC在第一网络 制式中释放对 UE的寻呼资源, 例如把 UE从寻呼队列中删除, 并根据 UE的 寻呼管理上下文、 UE的历史记录、运营商策略和该第一寻呼消息中携带的位 置区标识中的一种或几种, 确定寻呼范围。
若该第一网络制式与 UE的寻呼管理上下文中所记录的网络制式不相同, SRC还可以启动定时器 S, 等待从与 UE的寻呼管理上下文中所记录的网络 制式相同的第二网络制式的接口发来的对 UE的寻呼消息。 如果定时器 S超 时前,收到从第二网络制式的接口发来的对 UE的寻呼消息,则根据 UE的寻 呼管理上下文、 UE的历史记录、运营商策略和该第一寻呼消息中携带的位置 区标识中的一种或几种, 确定寻呼范围。
在第三种实现方式中, 第一网络设备发送的寻呼消息中携带有激活指示 信息, 该激活指示信息用以指示 UE的空闲状态信令缩减 ISR是否激活, 若 SRC接收一个寻呼消息中携带有该激活指示信息,且该激活指示信息指示 UE 的 ISR激活, 则 SRC不需要等待所有的寻呼消息都接收到, 就可以根据 UE 的寻呼管理上下文、 UE的历史记录、运营商策略或该第一寻呼消息中携带的 位置区标识中的一种或几种, 确定寻呼范围。
SRC向寻呼范围中的小区发起对该 UE的寻呼的具体过程可以为: SRC 向寻呼范围中的小区对应的第二网络设备发送寻呼消息, 第二网络设备再在 相应的小区中对 UE进行寻呼。
本实施例提供的统一无线控制器 SRC, SRC可以从不同网络制式下的接 口接收寻呼消息,根据寻呼消息和 UE的寻呼管理上下文确定 UE的寻呼管理 上下文中记录的网络制式下的寻呼范围, 实现对寻呼过程的优化, 尤其是避 免了 UE的 ISR激活时, 不同网络制式下的第一网络设备对 UE注册的位置 区中的所有小区都进行寻呼而造成的资源浪费。 提高了移动性管理效果。
在本实施例中, 所述 SRC接收到的所述寻呼消息中包括第一寻呼消息; 所述处理单元 32 具体用于若首先从与所述网络制式信息所指示的网络制式 相同的第一网络制式的接口接收到所述第一寻呼消息, 则根据所述 UE的历 史记录或预设策略, 或者, 当所述 UE的寻呼管理上下文中还记录有用以指 示所述 UE转入空闲态时所驻留的小区标识或者所述 UE转入空闲态后重定向 到的小区标识时, 根据所述小区标识, 在所述第一网络制式下确定所述寻呼 范围。
在本实施例中, 所述寻呼消息中携带有位置区标识;
所述处理单元 32还用于若在第一预设时间内未接收到所述 UE的寻呼响 应, 则根据所述第一寻呼消息中的位置区标识确定所述 UE在所述第一网络 制式下注册的所有小区;
所述寻呼单元 33还用于向所述 UE在所述第一网络制式下注册的所有小 区发起对所述 UE的寻呼。
在本实施例中,所述 SRC接收到的所述寻呼消息中还包括第二寻呼消息, 所述第一寻呼消息所属的第一网络制式与所述第二寻呼消息所属的第二网络 制式不同;
