本发明实施例提供了一种控制设备接入的方法。 其中， 在本实施例中， 控制网元上具 有一个或多个小区， 且控制网元内维护小区标识、 设备相关信息与能力值的对应关系。 参 见图 2， 该方法包括：
步骤 201 : 当待接入的 MTC (Machine Type Communication, 机型通信） 设备初始接入 到控制网元下的小区时，控制网元接收待接入的 MTC设备发送的设备标识和设备相关信息； 其中， 待接入的 MTC设备当开机启动后选择一个控制网元下的小区， 并通过初始附着 流程接入到选择的控制网元下的小区中，且待接入的 MTC设备在进行初始附着流程的过程 中将自身的标识以及相关信息发送给该控制网元。
其中， 待接入的 MTC设备的相关信息可以为待接入的 MTC设备的类型和 /或待接入的 MTC设备属于用户的标识等。 另外， 在本实施例中， 控制网元可以为 eNB或 MME。
步骤 202: 控制网元存储待接入的 MTC设备接入小区的标识、 待接入的 MTC设备的 标识和待接入的 MTC设备的相关信息三者之间的对应关系；
具体地， 控制网元将待接入的 MTC设备接入小区的标识、 待接入的 MTC设备的标识 和待接入的 MTC设备的相关信息作为一条记录并存储在本地的小区标识、设备标识与设备 相关信息的对应关系中。
步骤 203: 控制网元在本地的小区标识、设备相关信息与设备数量的对应关系中增加待 接入的 MTC设备接入小区的标识和待接入的 MTC设备的相关信息对应的设备数量；
具体地， 控制网元根据待接入的 MTC设备接入小区的标识和待接入的 MTC设备的相 关信息， 查找本地的小区标识、 设备相关信息与设备数量的对应关系， 如果查找出对应的 设备数量， 则增加查找的设备数量； 如果没有查找出对应的设备数量， 则设置设备数量的 初值， 将待接入的 MTC设备接入小区的标识、 待接入的 MTC设备的相关信息和设置的设 备数量作为一条记录并存储在本地的小区标识、 设备相关信息与设备数量的对应关系中。
其中， 增加查找的设备数量可以具体为： 将查找的设备数量加 1 ; 设置设备数量的初值 可以具体为： 设置设备数量的初值为 1。
其中， MTC设备接入到小区中， 就驻留在接入的小区中， MTC驻留在小区中可以分为 两种状态， 分别为连接态和空闲态； 如果 MTC设备需要进行业务时， 则 MTC设备进入连 接态并和网络侧建立连接来进行业务； 当 MTC设备完成进行的业务即 MTC设备进入空闲 态并释放和网络侧之间的连接。
其中， 当 MTC设备进入空闲态时， MTC设备启动自身的 TA (Tracking Area, 跟踪区 域）更新周期并在 TA更新周期超期时发起 TA更新流程以通知网络侧自己还驻留在小区中； 另外， MTC设备处于空闲态时， MTC设备可以从当前驻留的小区重选到另一个小区中驻留， 且 MTC设备在做重选小区时， 不通知控制网元， 所以控制网元并不知道 MTC设备是否做 重选操作， 即控制网元不知道是否有 MTC设备做重选操作驻留在其下的小区中或离开其下 的小区。
其中， 对于控制网元下的小区中驻留的任意一个 MTC设备当进行 TA更新时， 控制网 元就开始执行步骤 204。
步骤 204: 当待更新的 MTC设备在当前驻留小区中发起 TA更新时， 控制网元接收待 更新的 MTC设备在当前驻留小区发送的待更新的 MTC设备的标识和相关信息； 其中， 待更新的 MTC设备在进行 TA更新的流程中会发送自身的标识和相关信息给控 制网元。
步骤 205: 如果待更新的 MTC设备为最新选择到当前驻留小区中的设备， 则控制网元 存储当前驻留小区的标识、 待更新的 MTC设备的标识和待更新的 MTC设备的相关信息三 者之间的对应关系；
具体地， 控制网元根据当前驻留小区的标识和待更新的 MTC设备的标识， 查找本地的 小区标识、 设备标识与设备相关信息的对应关系， 如果没有查找出对应的设备相关信息， 则判断出待更新的 MTC设备为最新重选到当前驻留小区的设备， 将当前驻留小区的标识、 待更新的 MTC设备的标识和待更新的 MTC设备的相关信息作为一条记录并存储在本地的 小区标识、 设备标识与设备相关信息的对应关系中。
其中， 控制网元如果从小区标识、 设备标识和设备相关信息的对应关系中查找出对应 的设备相关信息， 则判断出待更新的 MTC设备不是最新重选到当前驻留小区中的设备， 而 是一直驻留在当前驻留小区中的设备。
步骤 206: 控制网元在本地的小区标识、设备相关信息与设备数量的对应关系中增加待 更新的 MTC设备当前驻留小区的标识和待更新的 MTC设备的相关信息对应的设备数量； 具体地， 控制网元根据待更新的 MTC设备当前驻留小区的标识和待更新的 MTC设备 的相关信息， 查找本地的小区标识、 设备相关信息与设备数量的对应关系， 如果查找出对 应的设备数量， 则增加查找的设备数量； 如果没有查找出对应的设备数量， 则设置设备数 量的初值， 将待更新的 MTC设备当前驻留小区的标识、 待更新的 MTC设备的相关信息和 设置的设备数量作为一条记录并存储在本地的小区标识、 设备相关信息与设备数量的对应 关系中。
其中， 当 MTC设备在当前驻留小区中从连接态进入空闲态时， 控制网元可以在本地的 小区标识、 设备标识与设备相关信息的对应关系中为包括当前驻留小区的标识、 该 MTC设 备的标识和相关信息的对应关系设置定时器；该定时器计时的时长大于 TA更新周期的周期 长度。
相应地， 对于本地的小区标识、 设备标识与设备相关信息中的任一条记录， 如果在该 条记录对应的定时器超时之前接收到该记录中的设备标识对应的 MTC设备在该记录中的小 区标识对应的小区中发起 TA更新时发送的设备标识和设备相关信息，则将该记录对应的定 时器清零； 如果在该条记录对应的定时器超时之前没有接收到该记录中的设备标识对应的 MTC设备在该记录中的小区标识对应的小区中发起 TA更新时发送的设备标识和设备相关 信息， 则删除该记录， 并在本地的小区标识、 设备相关信息与设备数量的对应关系中减少 该记录中的小区标识和设备相关信息对应的设备数量。
其中， 在控制网元下的小区中驻留的 MTC设备处于连接态， MTC设备和控制网元之 间具有连接并进行业务， 处于连接态的 MTC设备有时因业务需要等原因发生小区切换， 具 体为： MTC设备从当前驻留的小区即被切小区切入到其他小区中即切入小区中； MTC设备 当发生小区切换时， MTC设备会请求被切小区所在的控制网元释放已建立的连接， 并同时 发送自身的标识和相关信息给被切小区所在的控制网元， 当切入到切入小区中， MTC设备 请求切入小区所在的控制网元建立连接， 并同时发送自身的标识和相关信息给切入小区所 在的控制网元。
其中， 在本实施例中， 如果控制网元下的小区内驻留的 MTC设备发生小区切换切出当 前驻留的小区， 即待切出的 MTC设备从当前驻留的小区即被切小区中切换到其他小区中， 控制网元开始执行的步骤 207。
步骤 207: 当待切出的 MTC设备从控制网元下的被切小区切换到其他小区时， 控制网 元接收待切出的 MTC设备发送待切出的 MTC设备的标识和相关信息；
步骤 208: 控制网元删除被切小区的标识、待切出的 MTC设备的标识和待切出的 MTC 设备的相关信息三者之间的对应关系；
具体地， 控制网元从本地的小区标识、 设备标识与设备相关信息的对应关系中查找包 括被切小区的标识、 待切出的 MTC设备的标识和待切出的 MTC设备的相关信息的对应关 系， 删除查找的对应关系。
步骤 209: 控制网元在本地的小区标识、设备相关信息与设备数量的对应关系中减少被 切小区的标识和待切出的 MTC设备的相关信息对应的设备数量；
具体地， 控制网元根据被切小区的标识和待切出的 MTC设备的相关信息， 从本地的小 区标识、 设备相关信息与设备数量的对应关系中查找对应的设备数量， 减少查找的设备数 量。
其中， 减少查找的设备数据可以具体为： 将查找的设备数量减 1。
其中， 在本实施例中， 如果有 MTC设备发生小区切换切入到控制网元下的小区， 即待 切入的 MTC设备从其他小区切换到控制网元下的小区中， 控制网元开始执行的步骤 210。
