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 通技术人员在没有做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。
为了解决现有技术在 UE进行状态迁移的过程中， 接入网络侧设 备工作负载较大的问题， 本发明实施例提供一种状态迁移方法和网络 设备。
如图 1所示， 本发明实施例提供的状态迁移方法， 包括： 步骤 101， 判断 UE是否为频繁进行状态迁移的 UE;
步骤 102， 如果 UE为频繁进行状态转移的 UE， 当需要将用户设 备的状态迁移到空闲状态时， 将 UE的状态迁移到 PCH状态；
步骤 103， 如果 UE为非频繁进行状态转移的 UE， 当需要将用户 设备的状态迁移到空闲状态时， 将 UE的状态迁移到空闲状态。
本发明实施例提供的状态迁移方法， 当需要将 UE的状态迁移 ， 空闲状态时， 将频繁进行状态迁移的 UE迁移到 PCH状态， 使得接入 网络侧设备不需要为该 UE频繁建立 /释放无线接入承载， 降低了接入 网络侧设备在频繁进行状态迁移的 UE进行状态迁移过程中的工作负 载； 当需要将 UE的状态迁移到空闲状态时， 将非频繁进行状态转移 的 UE迁移到空闲状态， 使得接入网络侧设备不需要维护该非频繁进 行状态转移的 UE的 PCH状态， 降低了接入网络侧设备在非频繁进行 状态迁移的 UE进行状态迁移过程中的工作负载。
为了使本领域技术人员能够更清楚地理解本发明实施例提供的技 进行详细说明。
如图 2所示， 本发明另一实施例提供的状态迁移方法， 包括： 步骤 201， 获取 UE 的国 际移动设备标识型号核准号码 ( International Mobile Equipment Identity TAC , IMEI TAC ), 1"列 口， ^口 图 3所示， 可以包括：
步骤 2011， 向 UE发送身份请求 （ Identity Request )。
在本实施例中， 步骤 2011可以在 UE进行 RRC连接阶段进行； 也可以在接 4史到 UE发送的 Signaling Connection Release Indication之 后进行。 当然， 在实际的使用过程中， 还可以在其他阶段进行， 此处 不对每种情况进行——赘述。
步骤 2012，接收 UE根据 Identity Request返回的国际移动设备标 识 ( International Mobile Equipment Identity , IMEI )。
在本实施例中， IMEI可以携带在身份响应 （Identity Response ) 中。
步骤 2013， 从步骤 2012接收的 IMEI中获取 IMEI TAC。
步骤 202，根据步骤 201获取的 IMEI TAC判断 UE是否为频繁进 行状态迁移的 UE。
在本实施例中， 例如， 步骤 202可以包括：
首先， 从预先存储的 IMEI TAC与终端类型对应的关系表中， 查 找步骤 201获取的 IMEI TAC对应的终端类型信息。
例如， 本实施例可以将 UE的类型划分成两种： 一种是， 智能终 端， 该智能终端能够自动进行状态迁移， 状态迁移较频繁； 另一种是， 非智能终端， 该非智能终端不能自动进行状态迁移， 状态迁移次数较 少。 当然， 也可以将 UE的类型划分成两种： 一种是状态迁移较频繁 的终端； 另一种是， 状态迁移次数较少的终端。
在本实施例中， IMEI TAC 与终端类型对应的关系表可以包括： UE的 IMEI TAC和 UE对应的终端类型信息， 如表 1所示：
表 1 :
Figure imgf000006_0001
也可以预先将 IMEI TAC与终端类型对应的关系表中的终端类型 设置成默认值， 如终端类型为智能终端 （或者非智能终端）， 则此时 IMEI TAC与终端类型对应的关系表也可以仅包括 UE的 IMEI TAC， 即成为智能终端 （或者非智能终端） 对应的 IMEI TAC列表， 例如： 预先将 IMEI TAC与终端类型对应的关系表中的终端类型设置为智能 终端， 则此时 IMEI TAC与终端类型对应的关系表如表 2所示： 表 2 :
IMEI TAC
011776
356219
011775
本发明实施例不对 IMEI TAC与终端类型对应的关系表的具体形 式进行限定， 在实际的使用过程中， IMEI TAC 与终端类型对应的关 系表还可以为其他形式， 此处不做——赘述。
在本实施例中， IMEI TAC 与终端类型对应的关系表可以预先由 操作人员通过人机界面设置。
然后， 可以根据终端类型信息判断 UE是否为频繁进行状态迁移 的 UE。
在本实施例中， 如果终端类型信息为智能终端， 则 UE为频繁进 行状态迁移的 UE; 如果终端类型信息为非智能终端， 则 UE为非频繁 进行状态迁移的 UE。
步骤 203， 如果 UE为频繁进行状态转移的 UE， 当需要将 UE的 状态迁移到空闲状态时， 将 UE的状态迁移到 PCH状态。
在本实施例中， 确定需要将 UE的状态迁移到空闲状态， 可以是， 例如，如果接收到 UE发送的信令连接释放指示（ Signaling Connection Release Indication )， 则确定需要将 UE的状态迁移到空闲状态； 或者， 也可以预先设置一用于状态迁移检测的计时器， 当 UE处于专用信道 (Dedicated Channel, DCH)状态时启动该计时器， 如果在计时器的计时 时间内没有接收到 UE发送的业务数据， 则确定需要将 UE的状态迁 移到空闲状态。
当然， 在实际的使用过程中， 还可以通过其它方法确定是否需要 将 UE的状态迁移到空闲状态， 此处不对每种情况进行——赘述。
步骤 204， 如果 UE为非频繁进行状态转移的 UE， 当需要将 UE 的状态转移到空闲状态时， 将 UE的状态迁移到空闲状态。

在本实施例中， 步骤 4011可以在 UE进行 RRC连接阶段进行； 也可以在接 4史到 UE发送的 Signaling Connection Release Indication之 后进行。 当然， 在实际的使用过程中， 还可以在其他阶段进行， 此处 不对每种情况进行——赘述。
步骤 4012， 接收 UE根据 Direct Transfer Message返回的用户标 识。
在本实施例中， 如果用户标识为 TMSI， 则步骤 4012中用户标识 ( TMSI ) 可以携带在 UE发送的 RRC连接请求消息中； 如果用户标 识为 IMSI， 则步骤 4012 中用户标识 （IMSI ) 可以携带在 UE发送的 Identity Response中。
步骤 402， 根据步骤 401 获取的用户标识判断 UE是否为频繁进 行状态迁移的 UE。
在本实施例中， 例如， 步骤 402可以包括：
首先， 从预先存储的用户标识与终端类型的对应关系表中， 查找 步骤 401获取的用户标识对应的终端类型信息。 例如， 本实施例可以将 UE的类型划分成两种： 一种是， 智能终 端， 该智能终端能够自动进行状态迁移， 状态迁移较频繁； 另一种是， 非智能终端， 该非智能终端不能自动进行状态迁移， 状态迁移次数较 少。 当然， 也可以将 UE的类型划分成两种： 一种是状态迁移较频繁 的终端； 另一种是， 状态迁移次数较少的终端。
在本实施例中， 用户标识 （TMSI/IMSI ) 与终端类型对应的关系 表可以包括： 用户标识 （ TMSI/IMSI ) 和对应的终端类型信息， 如表 3所示：
表 3 :
Figure imgf000009_0001
也可以预先将用户标识 （TMSI/IMSI ) 与终端类型对应的关系表 中的终端类型设置成默认值， 如终端类型为智能终端 （或者非智能终 端）， 则此时用户标识 （ TMSI/IMSI )与终端类型对应的关系表也可以 仅包括用户标识 （TMSI/IMSI ), 即成为智能终端 （或者非智能终端） 对应的用户标识 （ TMSI/IMSI ) 列表， 例如： 预先将用户标识 ( TMSI/IMSI ) 与终端类型对应的关系表中的终端类型设置为智能终 端， 则此时用户标识 （ TMSI/IMSI ) 与终端类型对应的关系表如表 4 所示：
表 4:
用户标识 （ TMSI/IMSI )
800028967460070012340001
80002895/460070012340002
80002892/460070012340005
本发明实施例不对用户标识 （TMSI/IMSI ) 与终端类型对应的关 系表的具体形式进行限定， 在实际的使用过程中， 用户标识 ( TMSI/IMSI ) 与终端类型对应的关系表还可以为其他形式， 此处不 做——赘述。 在本实施例中， 用户标识 （TMSI/IMSI ) 与终端类型对应的关系 表可以预先由操作人员通过人机界面设置。
然后， 可以根据终端类型信息判断 UE是否为频繁进行状态迁移 的 UE。
在本实施例中， 如果终端类型信息为智能终端， 则 UE为频繁进 行状态迁移的 UE; 如果终端类型信息为非智能终端， 则 UE为非频繁 进行状态迁移的 UE。
步骤 403， 如果 UE为频繁进行状态转移的 UE， 当需要将 UE的 状态迁移到空闲状态时， 将 UE的状态迁移到 PCH状态。
在本实施例中， 确定需要将 UE的状态迁移到空闲状态， 可以是，
1"列^口， ^口果接 UE发送的 Signaling Connection Release Indication, 则确定需要将 UE的状态迁移到空闲状态； 或者， 也可以预先设置一 用于状态迁移检测的计时器， 当 UE处于 DCH状态时启动该计时器， 如果在计时器的计时时间内没有接收到 UE发送的业务数据， 则确定 需要将 UE的状态迁移到空闲状态。
当然， 在实际的使用过程中， 还可以通过其他方法确定是否需要 将 UE的状态迁移到空闲状态， 此处不对每种情况进行——赘述。
步骤 404， 如果 UE为非频繁进行状态转移的 UE， 当需要将 UE 的状态转移到空闲状态时， 将 UE的状态迁移到空闲状态。
本发明实施例提供的状态迁移方法， 当需要将 UE的状态迁移 ， 空闲状态时， 将频繁进行状态迁移的 UE迁移到 PCH状态， 使得接入 网络侧设备不需要为该 UE频繁建立 /释放无线接入承载， 降低了接入 网络侧设备在频繁进行状态迁移的 UE进行状态迁移过程中的工作负 载； 当需要将 UE的状态迁移到空闲状态时， 将非频繁进行状态转移 的 UE迁移到空闲状态， 使得接入网络侧设备不需要维护该非频繁进 行状态转移的 UE的 PCH状态， 降低了接入网络侧设备在非频繁进行 状态迁移的 UE进行状态迁移过程中的工作负载； 本发明实施例提供 的技术方案在降低接入网络侧设备信令面负载的同时控制 PCH 状态 用户的数量， 降低了接入网络侧设备逻辑资源的使用，保证系统容量。

步骤 602， 根据接收到的 UE发送的在线状态检查信息次数， 判 断 UE是否为频繁进行状态迁移的 UE。
在本实施例中， 可以预先设置次数门限， 例如： 设置次数门限为 2， 如果步骤 601接收的在线状态检测信息次数大于或等于次数门限， 则 UE为频繁进行状态迁移的 UE， 否则， UE为非频繁进行状态迁移 的 UE。
步骤 603， 如果 UE为频繁进行状态转移的 UE， 当需要将 UE的 状态转移到空闲状态时， 将 UE的状态迁移到 PCH状态。
