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。
本发明实施例提供一种机器终端接入网络的控制方法、装置和系统。 以下 分别进行详细说明。 实施例一、
本实例将从网络侧设备的角度进行描述。 该网络侧设备可以包括网管设 备、 网关、 MTC服务器、 MTC平台， 归属位置寄存器（HLR, Home Location Register )或用户位置数据库（HSS, Home Subscriber Server )等设备中的至 少一种。
一种机器终端接入网络的控制方法， 参见图 1 , 具体流程可以如下： 101、 根据需求信息生成时间受控签约的授权时段和 /或禁止时段； 其中，该需求信息可以包括网络业务负载历史数据和时间受控签约的应用 信息； 其中， 时间受控签约指的是包含时间受控特性的签约， 时间受控签约的 应用信息可以包括所有时间受控签约的机器终端数量和业务量等信息，或者某 一类时间受控签约的 MTC应用的机器终端数量和业务量等信息， 该需求信息 还可以包括系统维护时间。
例如， 具体可以如下：
( 1 )根据需求信息生成所有时间受控签约的授权时段和 /或禁止时段或某 一类时间受控签约的授权时段和 /或禁止时段；
比如， 授权时段定为每日凌晨的 3: 20 - 4: 00, 则每日凌晨的 3: 20 - 4: 00,所有时间受控签约或某一类时间受控签约的机器终端可以通过移动网络进 行通信， 而其他时间则被禁止通过移动网络进行通信；
又比如， 禁止时段定为每日的 9: 00 - 22: 00, 则每日的 9: 00 - 22: 00, 所有时间受控签约或某一类时间受控签约的机器终端都不可以通过移动网络 进行通信， 而其他时间 （即 22: 00 -次日 9: 00 )则允许通过移动网络进行通 信。
除了可以对所有时间受控签约的授权时段和 /或禁止时段或某一类时间受 控签约的机器终端进行统一控制之外，还可以对特定的某一个受控签约的机器 终端进行控制， 即还可以：
( 2 )根据需求信息生成特定一个时间受控签约的授权时段和 /或禁止时 段。
比如， 可以根据需求信息生成针对销售商 A的饮料自动贩卖应用设备的授 权时段和 /或禁止时段， 或者， 可以根据需求信息生成针对销售商 B的自动售报 应用设备的授权时段和 /或禁止时段等等。
其中， 需求信息还可以包括已有的时间受控签约的授权时段和 /或禁止时 段信息； 另外，此时需求信息中的时间受控签约的应用信息具体为特定一个时 间受控签约的应用信息， 比如应用类型 （入自动售货机、 抄表等）、 偏好通信 时段、 通信频度或周期、 平均 /最大数据量、 平均 /最大通信时长、 平均 /最大数 据率、 机器终端的数量和 MTC服务器的维护时间等信息的任意组合。
102、 将生成的授权时段和 /或禁止时段通知给机器终端；
例如， 可以通过广播的方式将将授权时段和 /或禁止时段广播给所有时间 受控签约或某一类时间受控签约对应的机器终端如下：
通过小区广播服务（CBS, Cell Broadcast Service )将授权时段和 /或禁止 时段广播给机器终端； 或者，
通过小区系统参数广播将授权时段和 /或禁止时段广播给机器终端。
当然， 也可以通过单播的方式将授权时段和 /或禁止时段广播给机器终端。 又例如， 还可以在接收到该时间受控签约的机器终端的第一接入请求后， 再将该授权时段和 /或禁止时段通知给该机器终端； 如下：
接收机器终端发送的第一接入请求； 根据第一接入请求将授权时段和 /或 禁止时段发送给该机器终端。
其中， 这里的第一接入请求指的是用于获取授权时段和 /或禁止时段的请 求消息， 具体实施时， 可以根据具体的应用环境所对应的协议要求进行设置， 比如， 该第一接入请求具体可以为附着（Attach )请求， 等等。 103、 接收到机器终端的接入请求后， 根据授权时段和 /或禁止时段对该机 器终端的接入进行控制；
例如， 当机器终端有通信需要，且已经进入授权时段（或非禁止时段）时， 则机器终端可以执行通信开始的随机化操作，即在授权时段内随机地选择某一 个时刻发送接入请求， 则网络侧设备在接收到该接入请求后，根据接入请求和 授权时段和 /或禁止时段判断当前是否进入授权时段或是否不在禁止时段， 若 是，则允许该机器终端接入；否则，如果还没进入授权时段或还处在禁止时段， 则拒绝该机器终端接入或允许该机器终端接入但为本次接入打上标识，以便后 续根据该标识作预置的处理， 比如额外收费等。 可选的， 可以提示机器终端拒 绝接入的原因。
这里的接入请求指的是机器终端为了接入网络而发送的各种请求消息，具 体实施时， 可以根据不同网络的协议要求而采用不同的请求消息， 比如 GPRS 网络中的附着（Attach )请求消息、 位置更新请求或业务请求等， 详见现有技 术， 在此不再赘述。
此外， 在根据授权时段和 /或禁止时段对机器终端的接入进行控制之前， 还可以判断该机器终端是否为时间受控签约的机器终端， 若是， 才根据授权时 段和 /或禁止时段对该机器终端的接入进行控制， 否则， 可以不对该机器终端 的接入进行控制。
由上可知，本实施例采用根据网络的业务负载历史数据和时间受控签约的 应用信息等信息生成时间受控签约的授权时段和 /或禁止时段， 然后根据该授 权时段和 /或禁止时段来控制机器终端接入网络， 由于可以灵活地控制机器终 端接入网络的时间， 所以可以灵活地控制机器终端的通信，从而可以降低机器 终端通信对普通终端通信的影响。例如， 可以尽量让机器终端在运营商网络的 业务低谷时段接入网络，避免网络堵塞的可能性，降低对普通终端通信的影响， 在保证普通终端的通信质量的同时， 机器终端本身的通信质量也得到保障。 实施例二、
除了实施例一中所描述的方法的之夕卜，还可以根据时间受控签约的授权时 段和 /或禁止时段在本地， 比如网络侧设备中的 SGSN或 MME上， 生成一个本 地的授权时段和 /或禁止时段， 当然， 该本地的授权时段和 /或禁止时段不能和 基础的授权时段和 /或禁止时段有沖突， 即该本地的授权时段和 /或禁止时段需 要在基础的授权时段或非禁止时段内， 其中， 基础的授权时段和 /或禁止时段 指的是实施例一步骤 101中根据需求信息生成的授权时段和 /或禁止时段； 参见 图 2, 具体流程可以如下：
201、 根据需求信息生成时间受控签约的授权时段和 /或禁止时段； 其中，该需求信息可以包括网络业务负载历史数据和时间受控签约的应用 信息； 其中， 时间受控签约指的是包含时间受控特性的签约， 时间受控签约的 应用信息可以包括所有时间受控签约的机器终端数量和业务量等信息，或者某 一类时间受控签约的 MTC应用的机器终端数量和业务量等信息， 该需求信息 还可以包括系统维护时间。
202、根据时间受控签约的授权时段和 /或禁止时段和预置的本地策略生成 本地的授权时段和 /或禁止时段；
其中， 预置的本地策略可以根据具体的环境或应用进行设置， 比如， 时区 或业务负载等。
203、 将本地的授权时段和 /或禁止时段发送给机器终端， 或者， 在本地的 授权时段和 /或非禁止时段内随机生成一个通信窗， 并将该通信窗发送给该机 器终端；
204、 接收到该机器终端的接入请求后， 根据本地的授权时段和 /或禁止时 段或者通信窗对该机器终端的接入进行控制。
比如判断当前是否进入本地的授权时段或是否不在本地的禁止时段， 若 是， 则允许该机器终端接入， 若否， 则拒绝该机器终端接入或允许该机器终端 接入但为本次接入打上标识， 以便后续根据该标识作预置的处理。
由上可知， 本实施例除了可以实现实施例一的有益效果之外，还可以根据 基础的授权时段和 /或禁止时段和本地策略生成更贴合本地实际环境的本地的 授权时段和 /或禁止时段， 更灵活地对时间受控签约的机器终端进行接入网络 控制。 实施例三、
对于实施例一和二中所描述的方法， 进一步， 还可以对授权时段和 /或禁 止时段进行更新， 参见图 3a, 具体可以如下： A301、 生成新的授权时段和 /或禁止时段、 或新的本地的授权时段和 /或禁 止时段、 或新的通信窗；
A302、 根据原授权时段和 /或禁止时段、 或原本地的授权时段和 /或禁止时 段、 或原通信窗确定机器终端的接入合法时， 允许该机器终端接入， 并将生成 的新的授权时段和 /或禁止时段、 或新的本地的授权时段和 /或禁止时段、 或新 的通信窗通知给机器终端。
机器终端在接收该新的授权时段和 /或禁止时段、 或新的本地的授权时段 和 /或禁止时段、 或新的通信窗后， 更新自身 （即机器终端）保存的授权时段 和 /或禁止时段或者本地的授权时段和 /或禁止时段或者通信窗， 在下次有通信 需要时， 根据该新的授权时段和 /或禁止时段、 或新的本地的授权时段和 /或禁 止时段、 或新的通信窗向网络侧发送接入请求。
或者， 参见图 3b, 也可以如下：
B301、 生成新的授权时段和 /或禁止时段、 或新的本地的授权时段和 /或禁 止时段、 或新的通信窗；
B302、 根据原授权时段和 /或禁止时段确定机器终端的接入合法时， 将生 成的新的授权时段和 /或禁止时段、 或新的本地的授权时段和 /或禁止时段、 或 新的通信窗通知给机器终端， 在根据新的授权时段和 /或禁止时段、 或新的本 地的授权时段和 /或禁止时段、 或新的通信窗确定机器终端的接入合法时， 才 允许该机器终端接入； 例如， 可以如下：
Bl、 网络侧设备根据原授权时段和 /或禁止时段、 或原本地的授权时段和 / 或禁止时段、或原通信窗确定机器终端的已进入原授权时段或非禁止时段， 或 者已进入原本地授权时段或非禁止时段、或进入原通信窗时，将生成的新的授 权时段和 /或禁止时段、 或新的本地的授权时段和 /或禁止时段、 或新的通信窗 通知给机器终端， 并拒绝该机器终端接入；
B2、 机器终端接收到该新的授权时段和 /或禁止时段、 或新的本地的授权 时段和 /或禁止时段、 或新的通信窗后， 更新自身 （即机器终端）保存的授权 时段和 /或禁止时段、 或本地的授权时段和 /或禁止时段、 或者通信窗； 等待下 次有通信需要，且已进入新的授权时段或非禁止时段、或进入新的本地授权或 非禁止时段、 或进入新的通信窗时， 发送接入请求给网络侧设备。 由上可知， 本实施例除了可以实现实施例一和实施例二的有益效果之外， 还可以根据实际需求的变化随时对授权时段和 /或禁止时段进行更新， 使其适 应实际需求， 提高通信质量。 实施例四、
本实例将从机器终端的角度进行描述。
一种机器终端接入网络的控制方法， 如图 4所示， 具体流程可以如下：
401、 与网络侧系统（网络侧系统至少包括网络侧设备 )进行时间同步， 即与网络侧设备进行时间同步；
例如， 通过全球定位系统（ GPS , Global Positioning System ) 实现同步， 或者， 可以接收移动网络广播的系统时间实现同步， 比如， 网络侧可以将该系 统时间可以和授权时段和 /或禁止时段一同广播给机器终端， 或者， 也可以在 机器终端在和 MTC服务器通信时进行时间同步， 等等。
402、 获取时间受控签约的授权时段和 /或禁止时段、 本地的授权时段和 / 或禁止时段或者通信窗中的至少一种参数； 其中，通信窗为网络侧设备在本地 的授权时段和 /或非禁止时段内随机生成的， 本地的授权时段和 /或禁止时段由 网络侧设备根据时间受控签约的授权时段和 /或禁止时段和预置的本地策略生 成的， 而时间受控签约的授权时段和 /或禁止时段则是由网络侧设备根据需求 信息生成；
其中， 需求信息包括网络业务负载历史数据和时间受控签约的应用信息； 其中，时间受控签约的应用信息可以包括所有时间受控签约的机器终端数量和 业务量等信息， 或者某一类时间受控签约的 MTC应用的机器终端数量和业务 量等信息。
该需求信息还可以包括已有的时间受控签约的授权时段和 /或禁止时段信 息； 另外， 此时需求信息中的时间受控签约的应用信息具体为特定一个时间受 控签约的应用信息， 比如应用类型（入自动售货机、 抄表等）、 偏好通信时段、 通信频度或周期、 平均 /最大数据量、 平均 /最大通信时长、 平均 /最大数据率、 机器终端的数量和 MTC服务器的维护时间等信息的任意组合。
此外， 该需求信息还可以包括系统维护时间等。
获取时间受控签约的授权时段和 /或禁止时段的方式具体可以如下： ( 1 )接收网络侧设备通过 CBS广播的时间受控签约的授权时段和 /或禁止 时段； 或者，
( 2 )接收网络侧设备通过小区系统参数广播的时间受控签约的授权时段 和 /或禁止时段； 或者，
( 3 )发送第一接入请求给网络侧设备； 接收网络侧设备根据第一接入请 求返回的本地的授权时段和 /或禁止时段或者时间受控签约的授权时段和 /或禁 止时段； 其中， 本地的授权时段和 /或禁止时段由网络侧设备根据时间受控签 约的授权时段和 /或禁止时段和预置的本地策略生成的。 这里的 "时间受控签 约的授权时段和 /或禁止时段" 可以是所有时间受控签约的授权时段和 /或禁止 时段， 或某一类时间受控签约的授权时段和 /或禁止时段， 或特定一个时间受 控签约的授权时段和 /或禁止时段。
其中， 预置的本地策略可以根据具体的环境或应用进行设备， 比如， 时区 或业务负载等。
另外， 这里的第一接入请求指的是用于获取授权时段和 /或禁止时段的请 求消息或普通的接入请求消息， 具体实施时， 可以根据具体的应用环境所对应 的协议要求进行设置， 比如， 该第一接入请求具体可以为 Attach请求， 业务请 求等等。 需说明的是， 该第一接入请求中还可以携带获取授权时段和 /或禁止 时段的指示， 用于表明该第一接入请求的目的在于获取授权时段和 /或禁止时 段。 或者，
( 4 )接收网络侧设备发送的通信窗， 该通信窗为网络侧设备在本地授权 时段和 /或非禁止时段内随机生成的。
403、 根据时间受控签约的授权时段和 /或禁止时段、 本地的授权时段和 / 或禁止时段或者通信窗发送接入请求给网络侧设备；
例如， 当机器终端有通信需要，且已经进入授权时段（或非禁止时段）时， 则机器终端可以执行通信开始的随机化操作，即在授权时段内随机地选择某一 个时刻发送接入请求给网络侧设备。
这里的接入请求指的是机器终端为了接入网络而发送的各种请求消息，具 体实施时， 可以根据不同网络的协议要求而采用不同的请求消息， 比如 GPRS 网络中的附着（Attach )请求消息、 位置更新请求或业务请求等， 详见现有技 术， 在此不再赘述。
404、 在网络侧设备根据接入请求以及网络侧设备存储的时间受控签约的 授权时段和 /或禁止时段、 本地的授权时段和 /或禁止时段或者通信窗中的至少 一种参数确定允许接入时， 接入网络。 也就是说， 在网络侧设备根据接入请求 和时间受控签约的授权时段和 /或禁止时段、 或者接入请求和本地的授权时段 和 /或禁止时段、 或者接入请求和通信窗确定接入合法时， 接入网络。
例如， 网络侧设备可以根据接入请求和授权时段和 /或禁止时段判断当前 是否进入授权时段或是否不在禁止时段，若是，则允许该机器终端接入；否贝 ij , 如果还没进入授权时段或还处在禁止时段， 则拒绝该机器终端接入， 或者允许 该机器终端接入但为本次接入打上标识， 以便根据该标识进行预置处理。
可选的， 机器终端还可以接收网络侧设备发送的关于拒绝接入原因的提 示。
可选的， 在机器终端接入网络之后， 与网络侧设备进行通信， 例如， 可以 采用如下方式进行通信：
发起分组数据协议 ( PDP, Packet Data Protocol )连接激活， 并和网络侧 设备进行通信； 或者，
使用默认承载 ( Default Bearer )和网络侧设备进行通信； 或者，
创建专用承载（Bearer ), 使用该创建的承载和网络侧设备进行通信。 上述通信方法详见现有技术， 在此不再赘述。
由上可知， 本实施例采用获取时间受控签约的授权时段和 /或禁止时段， 然后根据该授权时段和 /或禁止时段来接入网络； 其中， 该授权时段和 /或禁止 时段由网络侧设备根据网络的业务负载历史数据和时间受控签约的应用信息 等信息生成； 由于可以灵活地控制机器终端接入网络的时间， 所以可以灵活地 控制机器终端的通信，从而可以降低机器终端通信对普通终端通信的影响。例 如， 可以尽量让机器终端在运营商网络的业务低谷时段接入网络，避免网络堵 塞的可能性，降低对普通终端通信的影响，在保证普通终端的通信质量的同时， 机器终端本身的通信质量也得到保障。 实施例五、 根据前面实施例所描述的方法，在实施例五、六和七将举例进行详细说明。 本实施例将以通用分组无线月良务（ GPRS, General Packet Radio Service ) 网络为例进行详细说明， 需说明的是，该方案同样适用于演进分组系统（EPS, Evolved Packet System )。
其中， 网络侧设备包括网管设备、 GPRS服务支持节点（SGSN, Servicing GPRS Support Node ), 网关 GPRS支持节点 （ GGSN, Gateway GPRS Support Node ), MTC服务器和 HLR/HSS, 网络侧设备还可以包括 MTC平台， 参见图 5, 具体流程可以如下：
501、 机器终端与网络侧的系统进行时间同步；
例如， 通过 GPS实现同步， 或者， 可以接收移动网络广播的系统时间实现 同步，比如， 网络侧可以将该系统时间和授权时段一同广播给机器终端，或者， 也可以在机器终端和 MTC服务器通信时进行时间同步， 等等。
502、 网管设备或者 MTC平台根据需求信息生成所有时间受控签约的授权 时段或某一类时间受控签约的授权时段； 其中，任意一类时间受控签约的授权 时段可能不同， 也可能相同。
其中，需求信息可以包括网络的业务负载历史数据和时间受控签约的应用 信息， 还可以包括系统维护时间； 其中， 时间受控签约的应用信息可以包括所 有时间受控签约的机器终端数量和业务量等信息，或者某一类时间受控签约的 MTC应用的机器终端数量和业务量等信息。
该授权时段应设置在网络业务低谷时段， 且满足 MTC应用的通信需求。 比如， 若网络业务低谷期为凌晨 3:00 - 4:00, 那么可以将所有时间受控签约的 授权时段设为凌晨 3:00 - 4:00,则每日凌晨 3:00 - 4:00时段可以允许所有时间受 控签约的机器终端接入网络进行数据通信， 或者，如果运营商将时间受控签约 划分为 A、 B、 C三类， 可以将 A、 B、 C三类时间受控签约的授权时段分别设为 凌晨 3:00 - 3:20、 3:20 - 3:40、 3:40 - 4:00, 则每一类时间受控签约的机器终端 根据各自的授权时段接入网络进行数据通信， 即 A类时间受控签约的机器终端 可以在凌晨 3:00 - 3:20接入网络进行数据通信； B类时间受控签约的机器终端 可以在凌晨 3:20 - 3 :40接入网络进行数据通信； C类时间受控签约的机器终端 可以在凌晨 3:40 - 4:00接入网络进行数据通信。 这里的网管设备指提供电信业务的后台运维支撑系统，其功能可以包括电 信网络的网元管理、 资源管理和调度、业务开通、业务管理、业务质量保障等。 所以， 具体实现时， 可以将机器终端的接入网络控制包含到网管设备的资源管 理和资源调度功能中。
这里的 MTC平台也可以称为 MTC网关， 支持公众陆地移动网络（ PLMN , Public Land Mobile Network )和 MTC服务器的互通， 它提供数据路由、 监控、 用户鉴权、 计费等管理功能， 向 MTC服务器提供标准化的接口， 使得 MTC通 信筒单直接。 所以， 具体实施时， 也可以将机器终端的接入网络控制纳入 MTC 平台的管理功能中。
需说明的是， 网管设备或者 MTC平台可以在预设条件触发下重新生成授 权时段， 该预设条件可以根据实际需求进行设定， 比如， 网络又新部署了一定 数量的时间受控签约的机器终端， 或者， 系统维护时间发生了变化， 等等， 则 此时触发网管设备或者 MTC平台重新生成授权时段。 当然， 对于新部署的时 间受控签约的机器终端， 也可以直接分配已经生成的授权时段给它们。
503、 网管设备或者 MTC平台将生成的授权时段通知给机器终端； 比如， 可以采用如下任一种方式将授权时段通知给机器终端：
( 1 )可以通过 CBS将授权时段广播给机器终端， 即利用 CBS广播消息将 授权时段通知给机器终端；
需说明的是， 为了指示该 CBS广播消息是用于时间受控签约应用， 可以在 CBS广播消息中设置一个特定消息标识符（Message Identifier ) , 以便和其它 CBS广播消息支持的应用区分开来。 当然， 也可以为每一类时间受控签约都分 别分配一个消息标识符。
( 2 )通过小区系统参数广播将授权时段广播给机器终端。
( 3 )其他的广播或组播方式。
( 4 )单播方式， 比如， 将生成的授权时段写入 HLR/HSS的签约数据中， 然后在机器终端的附着、 位置更新和业务请求等过程中通过 SGSN下发授权时 段给机器终端， 在此不再赘述。
504、 网管设备或者 MTC平台可以将授权时段通知给相关的所有 SGSN , 也可能仅通知给有时间受控签约的机器终端接入的部分 SGSN,使得 SGSN后续 可以基于该授权时段对时间受控签约的机器终端的网络接入进行控制，允许机 器终端在授权时段接入网络， 拒绝机器终端在授权时段外的接入请求， 或者， 允许机器终端在授权时段外的接入请求但对本次接入进行标记以便进行预置 的处理， 比如， 对标记后的机器终端可以进行特殊计费等。
需说明的是， 网管设备或者 MTC平台也可以不直接将授权时段通知给 SGSN, 而是将生成的授权时段和 /或禁止时段写入 HLR/HSS的签约
( Subscription )数据（或称用户数据） 中， 然后 SGSN在接收到机器终端的接 入请求时，再从 HLR/HSS中获取相应的签约数据并进行处理， 比如根据签约数 据中的授权时段对机器终端接入网络进行控制，或者根据签约数据中的授权时 段生成本地授权时段， 然后才根据本地授权时段对机器终端接入网络进行控 制， 等等， 可参见实施例六， 在此不再赘述。
505、 可选的， 网管设备或者 MTC平台可以将授权时段通知给相关的 MTC 服务器， 使得 MTC服务器可以确定和机器终端进行通信的时机。
506、 当机器终端存在通信需要， 且已经进入授权时段时， 机器终端执行 随机化操作， 即在授权时段内随机地选择某一时间以接入网络， 并且随机化操 作应确保在授权时段停止时间前完成机器终端的通信；
比如， 机器终端利用均匀随机函数生成一个 0到 1之间的数 a, 则选择时间 t 接入网络， 其中， t =授权时段开始时间 + a*授权时段长。
需说明的是， 为了使得机器终端能够在授权时段停止时间前完成通信，应 保证 "(1-a)*授权时段长" 大于机器终端所需通信时间， 所以， 若生成的 a不能 满足该要求， 则需要重新生成一个随机数 a。
需说明的是， 当机器终端存在通信需要， 但当前未进入授权时段时， 机器 终端也可能发起网络接入请求，比如，附着请求、位置更新请求或业务请求等。
507、 机器终端发起 Attach请求到 SGSN, 以请求接入网络。
508、 SGSN从 HLR/HSS中下载签约数据（或称用户数据） ， 该签约数据 中包含时间受控信息， 比如包含时间受控特性（Feature )标志位， 时间受控应 用类别等信息；
509、 如果签约数据表明该终端是时间受控签约的机器终端， 则判断当前 是否进入网管设备或者 MTC平台通知的授权时段， 若否， 则返回附着拒绝消 息 （ Attach Reject ) , 指示机器终端网络接入失败， 结束本流程； 若是， 则返 回附着接受消息（ Attach Accept ) , 执行步骤 510。
510、机器终端发起 PDP Context激活， SGSN指示 GGSN创建 PDP Context, 并指示无线接入网（ RAN, Radio Access Network)建立无线接入 载（ RAB, Radio Access Bear) 。
511、 机器终端和 MTC服务器进行 MTC通信。
512、 可选的， 通信完成后， 机器终端发起 PDP Context去激活， SGSN指 示 GGSN删除 PDP context。
可选的，如果机器终端后续较长时间都没有通信的需求，机器终端可以执 行隐含分离 /隐含去附着（Implicit Detach ) , SGSN在时间受控信息的触发下也 可以执行隐含 Detach。
除了上述步骤 510 ~ 511中所描述的通信方法外，机器终端还可以使用默认 承载（Default Bearer )和 MTC服务器进行通信； 或者， 创建专用承载和 MTC 服务器进行通信。
由上可知， 本实施例采用根据网络的业务负载历史数据、 系统维护时间和 时间受控签约的应用信息等信息生成所有时间受控签约的授权时段或某一类 时间受控签约的授权时段， 然后根据该授权时段来控制机器终端的网络接入， 由于可以灵活地控制机器终端接入网络的时间，所以可以灵活地控制机器终端 的通信， 从而可以降低机器终端通信对普通终端通信的影响。 例如， 可以尽量 让机器终端在运营商网络的业务低谷时段接入网络， 避免网络堵塞的可能性， 降低对普通终端通信的影响，在保证普通终端的通信质量的同时，机器终端本 身的通信质量也得到保障。 实施例六、
在实施例五中， 网管设备或者 MTC平台生成的是所有时间受控签约的授 权时段和 /或禁止时段或某一类时间受控签约的授权时段和 /或禁止时段， 而在 本实施例中， 将以网管设备或者 MTC平台生成特定一个时间受控签约的授权 时段和 /或禁止时段为例进行说明， 即本实施例中任意一个时间受控签约的授 权时段可能不同， 也可能相同。
同实施例五， 本实施例也以 GPRS网络为例进行详细说明， 需说明的是， 该方案同样适用于 EPS。
其中，网络侧设备包括网管设备、 SGSN、 GGSN、 MTC服务器和 HLR/HSS, 网络侧设备还可以包括 MTC平台， 参见图 6, 具体流程可以如下：
601、 机器终端与网络侧的系统进行时间同步；
例如， 通过 GPS实现同步， 或者， 可以接收移动网络广播的系统时间实现 同步， 或者， 也可以在机器终端和 MTC服务器通信时进行时间同步， 等等。
602、 网管设备或者 MTC平台根据需求信息生成特定一个时间受控签约的 授权时段， 比如一天或者一周或者一个月中的一个或多个时间段； 还可以生成 其他时间受控信息， 比如禁止时段、 通信持续时间等。
其中， 需求信息可以包括网络的业务负载历史数据、特定一个时间受控签 约的应用信息， 还可以包括系统维护时间和 /或已有的时间受控签约的授权时 段信息。 其中， 该特定一个时间受控签约的应用信息具体可以为应用类型（自 动售货机、 抄表等） 、 偏好通信时段、 通信频度或周期、 平均 /最大数据量、 平均 /最大通信时长、平均 /最大数据率、机器终端的数量和 /或 MTC服务器的维 护时间等信息。
该授权时段应设置在业务低谷时段， 且满足 MTC应用的通信需求。
603、 网管设备或者 MTC平台将生成的授权时段写入 HLR/HSS的签约数据 中， 当然， 如果在步骤 602中， 还生成了其他时间受控信息， 比如禁止时段、 通信持续时间等， 则也写入 HLR/HSS的签约数据中。
可选的， 网管设备或者 MTC平台还可以将生成的授权时段通知给 SGSN, 参见实施例五， 在此不再赘述。
604、 网管设备或者 MTC平台将生成的授权时段等时间受控信息通知给相 关的 MTC服务器， 以便 MTC服务器确定和机器终端进行通信的时机。
605、 当机器终端确定自身没有合法的授权时段时或者在维护人员的现场 操作等触发下， 机器终端发起 Attach请求给 SGSN, 以获取授权时段。 具体可 以采用如下任一种方式：
( 1 ) Attach请求中可以携带扩展的 Attach类型 （ Attach type ) , 用于指示 该 Attach请求的目的是获取授权时段；
其中， Attach type扩展如表一所示；
Figure imgf000020_0001
在现有技术中， 一般可以用 3个比特位来标识 attach的类型 （ Type of attach ) , 比如， 001表示 GPRS附着 （ GPRS attach ) , 010未使用， 011表示联 合 GPRS/国际移动用户识别码（ IMSI, International Mobile Subscriber
Identification Number) 附着， 100表示紧急呼叫附着， 而 101则为本发明实施例 所扩展的， 表示本次附着目的是获取授权时段。
需说明的是， 这里所说的授权时段可能是签约时间的授权时段（即前面实 施例所说的基础授权时段）， 也可能是本地授权时段， 也可能是通信窗， 具体 可以根据运营商的策略而定。
( 2 )不扩展 Attach类型，即沿用现有技术中的 Attach类型，比如" GPRS 附 着" 。 可选的， 机器终端还可以使用其它扩展信息向网络指示获取授权时段。
606、 若 SGSN本地没有该机器终端的签约数据， 则 SGSN向 HLR/HSS获取 签约数据， 该签约数据中包含了授权时段信息。
如果机器终端的 Attach请求明确指示要获取授权时段（比如，采用步骤 605 中的第一种方式） ， 则为了筒化操作， SGSN此时可以不判断当前是否进入授 权时段， 而直接通过 Attach Reject发送授权时段给机器终端。 当然， SGSN此时 也可以判断当前是否进入授权时段， 若当前已经进入授权时段， 则 SGSN可能 接受附着请求并返回 Attach Accept给机器终端， 并在该 Attach Accept响应中携 带授权时段。
如果该 Attach请求未明确指示要获取授权时段， 则 SGSN在根据签约数据 获知该终端是时间受控签约的机器终端时， 通过 Attach Reject或者 Attach Accept下发授权时段给机器终端。
其中， 可以将现有的 Attach Reject响应进行扩展， 使其可以携带授权时段 扩展信息。 参见表二；
Figure imgf000021_0001
Figure imgf000021_0002
同理， 也可以将现有的 Attach Accept响应进行扩展， 使其可以携带授权 时段扩展信息， 参见表三；
表三：
Figure imgf000021_0003
其中， 表二和表三中的 "Access Grant time interval" 是本发明实施例所扩 展的， 表示授权时段。 另夕卜， 表二中的 GMM cause的取值也需要设定为一个扩 展的取值， 用于表示拒绝原因为 "机器终端获取授权时段" 。
由于各个网络地区（比如乌鲁木齐市的网络、 北京市的网络）的时区或业 务负载等实际网络环境会有差异， 为了更好地适应实际网络环境， 可选的，
SGSN还可以根据签约数据中的授权时段、禁止时段和 SGSN的本地策略生成本 地的授权时段， 筒称为本地授权时段， 该本地授权时段不应和禁止时段交叠。 具体可以有一个或多个禁止时段，比如，为了避开 HLR/HSS的维护时间或 MTC server的维护时间 （两者的时间可能不同） ， 可能设置相应的禁止时段。
其中， 本地策略可以根据具体的环境或 MTC应用进行设置， 比如， 时区 或业务负载历史数据等。
机器终端将接收到的授权时段，比如将接收到的签约数据中的授权时段或 SGSN生成的本地授权时段保存起来， 这样， 机器终端可基于授权时段信息合 理地配置自身的操作和适时发起网络接入。
需说明的是， 为了节省信令开销， 如果 SGSN向 HLR/HSS获取签约数据时 包含扩展的获取授权时段指示， 则 HLR/HSS可以不需要向 SGSN发送完整的签 约数据， 而只需发送授权时段和禁止时段等内容。
607、 当机器终端存在通信需要， 且已经进入授权时段时， 执行随机化操 作， 即在授权时段内随机地选择某一时间以接入网络， 并且随机化操作应确保 在授权时段停止时间前完成机器终端的通信；
比如， 机器终端利用均匀随机函数生成一个 0到 1之间的数 a, 则选择时间 t 接入网络， 其中， t =授权时段开始时间 + a*授权时段长。
需说明的是， 为了使得机器终端能够在授权时段停止时间前完成通信，应 保证 "(1-a)*授权时段长" 大于机器终端所需通信时间， 所以， 若生成的 a不能 满足该要求， 则需要重新生成一个随机数 a。
608、 机器终端发起 Attach请求到 SGSN, 以请求接入网络。 Attach类型可 以是 GPRS附着或联合 GPRS/IMSI附着等。
609、 如果 SGSN保存有机器终端的签约数据 (比如在步骤 606中将获取到 的签约数据进行保存） ， 则判断当前是否进入签约数据中的授权时段， 若否， 返回 Attach Reject指示机器终端网络接入失败， 或者， 允许机器终端在授权时 段外的接入请求但对本次接入进行标记， 以便进行预置的处理， 比如， 对标记 后的机器终端可以进行特殊计费等； 若是， 返回 Attach Accept, 继续执行后续 步骤 610。如果 SGSN没有保存机器终端的签约数据，则此时还需要从 HLR/HSS 获取签约数据， 再执行上述判断操作。
需说明的是， 如果在步骤 606中， SGSN生成了本地授权时段， 并将本地授 权时段通知给机器终端，则应判断当前是否进入本地授权时段而不是签约数据 中的授权时段， 如下：
如果 SGSN保存有机器终端的签约数据和本地授权时段， 则判断当前是否 进入本地授权时段， 若否， 返回 Attach Reject, 指示机器终端网络接入失败， 或者， 允许机器终端在授权时段外的接入请求但对本次接入进行标记， 以便进 行预置的处理； 若是， 返回 Attach Accept, 继续执行步骤 610。
如果 SGSN中没有保存机器终端的签约数据， 则 SGSN从 HLR/HSS获取签 约数据， 并基于签约数据中的授权时段、 禁止时段信息和 SGSN本地策略生成 本地授权时段，然后判断当前是否进入本地授权时段，若否，返回 Attach Reject, 并指示机器终端网络接入失败， 或者， 允许机器终端在授权时段外的接入请求 但对本次接入进行标记， 以便进行预置的处理； 若是， 返回 Attach Accept, 继 续执行步骤 610。
610、 机器终端发起 PDP Context激活， SGSN指示 GGSN创建 PDP Context, 并指示 RAN建立无线接入承载 RAB。
611、 机器终端和 MTC服务器进行 MTC通信。
612、 可选的， 通信完成后， 机器终端发起 PDP Context去激活， SGSN指 示 GGSN删除 PDP context。
可选的，如果机器终端后续较长时间都没有通信的需求，机器终端可以执 行隐含分离 /隐含去附着（Implicit Detach ) , SGSN在时间受控信息的触发下也 可以执行隐含 Detach。
除了上述步骤 610 ~ 611中所描述的通信方法外，机器终端还可以使用默认 承载（Default Bearer )和 MTC服务器进行通信； 或者， 创建专用承载和 MTC 服务器进行通信。
由上可知， 本实施例根据网络的业务负载历史数据、 系统维护时间和时间 受控签约的应用信息等信息生成特定一个时间受控签约的授权时段，由于该特 定时间受控签约的应用信息包括了更多的详细信息， 比如应用类型、偏好通信 时段、 通信频度或周期、 平均 /最大数据量、 平均 /最大通信时长、 平均 /最大数 据率、 机器终端的数量和 /或 MTC服务器的维护时间等信息， 所以可以实现更 加精细的网络接入控制。 而且， SGSN还可以根据签约数据中的 （基础）授权 时段、 禁止时段和 SGSN本地策略生成更贴合实际网络环境的本地授权时段， 更灵活地实现对特定一个时间受控签约的机器终端接入网络的控制。 实施例七、
在实施例五和六的基础上，还可以对生成的时间受控签约的授权时段进行 更新。
其中，网络侧设备包括网管设备、 SGSN, GGSN、 MTC服务器和 HLR/HSS, 网络侧设备可能包括 MTC平台， 参见图 7, 具体流程可以如下：
701、 网管设备或者 MTC平台重新生成时间受控签约的授权时段， 得到新 的授权时段， 还可能重新生成禁止时段、 通信持续时间等其他时间受控信息， 具体生成同实施例五和六， 在此不再赞述。
702、 网管设备或者 MTC平台将生成的新的授权时段写入 HLR/HSS的签约 数据中， 当然， 如果在步骤 701中， 还生成了其他时间受控信息， 比如禁止时 段、 通信持续时间等， 则也写入 HLR/HSS的签约数据中。
可选的， 也可以将新生成的授权时段通知给 SGSN。
703、 网管设备或者 MTC平台将生成的新的授权时段通知给相关的 MTC服 务器， 以便 MTC服务器确定和机器终端进行通信的时机。
当然， 如果在步骤 701中， 还生成了其他时间受控信息， 比如禁止时段、 通信持续时间等， 则也以通知给相关的 MTC服务器。
704、 当机器终端存在通信需要， 且已经进入旧的授权时段时， 执行随机 化操作， 即在旧的授权时段内随机地选择某一时间以接入网络。
705、 机器终端发起 Attach请求给 SGSN, Attach类型指示 GPRS Attach, 以 请求接入网络。
706、 SGSN向 HLR/HSS获取签约数据。
707、 HLR/HSS发送签约数据给 SGSN, 该签约数据可以包括旧的授权时 段和新的授权时段， 当然， 如果 SGSN中还保存有旧的授权时段的话， 也可以 只发送新的授权时段， SGSN根据旧的授权时段判断该机器终端当前是否已进 入旧的授权时段， 若否， 则返回 Attach Reject; 若是， 则 SGSN向机器终端发送 Attach Accept SGSN在 Attach Reject或 Attach Accept 中携带新的授权时段发 送给机器终端。
当然， 如果之前是本地授权时段来对机器终端的接入进行控制的话， 贝 ij SGSN可以根据签约数据中的新的授权时段和预置的本地策略生成新的本地授 权时段，并根据旧的本地授权时段判断该机器终端当前是否已进入旧的本地授 权时段， 若否， 则返回 Attach Reject; 若是， 则 SGSN在接受机器终端接入的同 时， 向机器终端发送新的本地授权。
机器终端接收到新的授权时段或新的本地授权时段后，将其保存， 并覆盖 旧的本地授权时段等时间受控签约信息， 以便下次通信时使用。
或者， 可选的， SGSN也可以直接根据新的授权时段判断该机器终端当前 是否已进入新的授权时段， 若否， 则返回 Attach Reject, 并在 Attach Reject中携 带新的授权时段； 若是， 则允许机器终端接入， 并返回 Attach Accept。 SGSN 在 Attach Reject或 Attach Accept中携带新的授权时段发送给机器终端。
步骤 708 ~ 710同实施例六中的步骤 610 ~ 612, 在此不再赘述。
可选的，如果机器终端后续较长时间都没有通信的需求，机器终端可以执 行隐含 Detach, SGSN在时间受控签约信息的触发下也可以执行隐含 Detach。
由上可知， 本实施例除了可以实现实施例六的有益效果之外，还可以根据 实际需求的变化随时对授权时段和 /或禁止时段进行更新， 使其适应实际需求， 提高通信质量。
另外， 还需说明的是， 进一步的， 在实施例五、 六和七中， 若签约数据中 包含通信持续时间， 则 SGSN还可能基于本地策略随机生成一个授权时段内或 者本地授权时段内的通信窗， 并将该通信窗发送给机器终端， 而不必将授权时 段发送给机器终端， 则机器终端不必再执行随机化操作， 而是直接在通信窗开 始时间发起网络接入即可。可以理解的是， 此处由网络执行随机化操作代替了 机器终端的随机化操作， 加强了运营商的控制力。 另外， 机器终端的接入请求 有多种， 除了实施例五、 六和七中所举例的附着请求之外， 还可以是位置更新 请求或业务请求等， 在此不再赘述。 实施例八、
为了更好地实施以上方法， 本发明实施例还相应地提供一种网络侧设备， 如图 8a所示， 该网络侧设备包括生成单元 801、 通知单元 802和处理单元 803; 生成单元 801 , 用于根据需求信息生成时间受控签约的授权时段和 /或禁止 时段， 其中， 该需求信息可以包括网络业务负载历史数据和时间受控签约的应 用信息；

处理单元 803 , 用于接收到该机器终端的接入请求后， 根据生成单元 801 生成的授权时段和 /或禁止时段对该机器终端的接入进行控制。
比如， 接收到该机器终端的接入请求后， 根据生成单元 801生成的授权时 段和 /或禁止时段确定接入合法时， 允许该机器终端接入， 否则， 若接入不合 法， 则拒绝该机器终端接入， 等等。
这里的接入请求指的是机器终端为了接入网络而发送的各种请求消息，具 体实施时， 可以根据不同网络的协议要求而采用不同的请求消息， 比如 GPRS 网络中的附着 （Attach )请求消息等， 详见现有技术， 在此不再赘述。
其中， 生成单元 801至少可以包括以下任一种单元： 第一生成子单元、 第 二生成子单元和第三生成子单元；
第一生成子单元，用于根据需求信息生成所有时间受控签约的授权时段和 /或禁止时段；
第二生成子单元，用于根据需求信息生成某一类时间受控签约的授权时段 和 /或禁止时段；
比如， 授权时段定为每日凌晨的 3: 20 - 4: 00, 则每日凌晨的 3: 20 - 4:
00,所有时间受控签约或某一类时间受控签约的机器终端可以通过移动网络进 行通信， 而其他时间则被禁止通过移动网络进行通信；
又比如， 禁止时段定为每日的 9: 00 - 22: 00, 则每日的 9: 00 - 22: 00, 所有时间受控签约或某一类时间受控签约的机器终端都不可以通过移动网络 进行通信， 而其他时间 （即 22: 00 -次日 9: 00 )则允许通过移动网络进行通 信。
除了上述所说的可以对所有时间受控签约的授权时段和 /或禁止时段或某 一类时间受控签约的机器终端进行统一控制之外，还可以对特定一个时间受控 签约的机器终端进行控制， 即：
第三生成子单元，用于根据需求信息生成某一个时间受控签约的授权时段 和 /或禁止时段。
比如， 可以根据需求信息生成针对销售商 A的饮料自动贩卖应用设备的授 权时段和 /或禁止时段， 或者， 可以根据需求信息生成针对销售商 B的自动售报 应用设备的授权时段和 /或禁止时段等等；
此时的需求信息还可以包括已有的时间受控签约的授权时段和 /或禁止时 段信息； 另外，此时需求信息中的时间受控签约的应用信息具体为特定一个时 间受控签约的应用信息， 比如应用类型 （入自动售货机、 抄表等）、 偏好通信 时段、 通信频度或周期、 平均 /最大数据量、 平均 /最大通信时长、 平均 /最大数 据率、 机器终端的数量和 /或 MTC服务器的维护时间等信息。

如图 8b所示， 其中， 处理单元 803可以包括判断子单元 8031、 接入子单元 8032和处理子单元 8033;
判断子单元 8031 ,用于在接收到机器终端的接入请求后，根据生成单元 801 生成的授权时段和 /或禁止时段确定是否允许该机器终端的接入， 比如判断当 前是否进入授权时段或是否不在禁止时段；
接入子单元 8032, 用于在判断子单元 8031确定为是时， 允许该机器终端接 入， 比如， 在判断子单元 8031确定当前已进入授权时段或不在禁止时段时， 允 许该机器终端接入；
处理子单元 8033 ,用于在判断子单元 8031为否时，比如，在判断子单元 8031 确定当前尚未进入授权时段或在禁止时段时，拒绝该机器终端接入， 或允许该 机器终端接入但为本次接入打上标识， 以便根据该标识进行预置处理， 比如进 行额外的收费等。
需说明的是， 这里的第一接入请求指的是用于获取授权时段和 /或禁止时 段的请求消息， 具体实施时， 可以根据具体的应用环境所对应的协议要求进行 设置， 比如， 该第一接入请求具体可以为 Attach请求， 等等。
如图 8b所示， 该网络侧设备还可以包括更新单元 804;
生成单元 801 , 还用于生成新的授权时段和 /或禁止时段；
更新单元 804, 用于根据原授权时段和 /或禁止时段确定机器终端的接入合 法时， 允许机器终端接入， 并将生成单元 801生成的新的授权时段和 /或禁止时 段通知给机器终端； 或者， 根据原授权时段和 /或禁止时段确定机器终端的接 入合法时， 将生成单元 801生成的新的授权时段和 /或禁止时段通知给机器终 端， 在根据新的授权时段和 /或禁止时段确定机器终端的接入合法时， 才允许 该机器终端接入。
具体实施时， 该网络侧设备可以作为一个独立的实体实现，也可以划分为 多个实体实现，例如，该网络侧设备具体可以包括网管设备/ MTC平台、 SGSN, / GGSN、 MTC服务器和 HLR/HSS, 等等。
以上各个单元的具体实施可参见前面实施例， 在此不再赞述。
