Entity )从用户归属服务器 HSS中获得该 MTC设备的签约信息, 并保存在 本地。 MME是核心网中用于管理用户终端控制消息的实体,负责接入控制, 包括鉴权控制,标识(全球唯一临时标识( GUTI, Globally Unique Temporary Identity ), 跟踪区标识列表( TAI list, Tracing Area Identity list ) )指配, 用 户标识和设备标识验证, 消息面加密, 与基站(eNB )之间的一致性保护, 2G ( 2nd Generation ) /3G ( 3rd Generation )与演进的分组***( EPS , Evolved Packet System )之间安全参数以及服务质量(QoS, Quality of Service )参 数的转换, 接入许可控制, 决定是否可以获得请求的资源并预留这些资源, 合法监听, 移动性管理(实现对 UE当前位置的跟踪和记录), 会话管理, 对 EPS承载的相关操作, 以及网元选择等。
对于 MTC的时间控制特性, 要求网络能控制对 MTC设备接入请求或 数据收发的控制, 即在指定时间以外的消息或数据, 网络应该拒绝, 而只 接收或处理指定时间以内的消息或数据。
当前, 对 MTC设备的时间控制特性尚处于讨论阶段, 如何利用该时间 控制特性实现对 MTC设备接入进行控制, 目前尚没有统一的技术实现方

为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
实施例一
步骤 201 ,终端入网时,终端用户将该终端签约为具有时间可控特性(即 时间控制特性)的 MTC终端, 并与运营商协商时间控制特性信息: 允许接 入时间段, 禁止接入时间段等。 上述时间控制特性信息中的两个时间段可 以重复出现, 也可以是单次有效。 各时间段具体表示方式如下:
方式一:
允许接入时间段: 开始时间, 结束时间, 可选地还包含时间段重复周 期;
禁止接入时间段: 开始时间, 结束时间, 可选地还包含时间段重复周 期;
示例如下:
允许接入时间段:
开始时间: 2011年 3月 7日 11:00;
结束时间: 2011年 3月 7日 12:00。
如果不包含时间段重复周期, 则表示缺省按照周期为一天 24小时重复 该时间段(则下一次允许时间段是 2011年 3月 8日 11:00至 12:00 ), 或者 表示为不重复(即仅在 2011年 3月 7 日 11:00至 12:00允许所述终端接入 网络); 如果还包含时间段重复周期, 例如重复周期为一个月, 则下一次允 许时间段是 2011年 4月 7日 11:00至 12:00。
禁止接入时间段:
表示方式如上述允许接入时间段, 但是时间上要求不能和允许接入时 间段有重叠。 例如可以是除上述允许接入时间段之外的时间段, 或与上述 允许接入时间段不重叠的其他时间段, 如设置为网络负荷较重的时间段。
方式二:
允许接入时间段: 开始时间, 时长, 可选地还包含时间段重复周期; 禁止接入时间段: 开始时间, 时长, 可选地还包含时间段重复周期; 示例如下:
允许接入时间段:
开始时间: 2011年 3月 7日 11:00;
允许接入时长: 1小时。
如果不包含时间段重复周期, 则表示缺省按照周期为一天 24小时重复 该时间段(则下一次允许时间段是 2011年 3月 8日 11:00至 12:00 ), 或者 表示为不重复; 如果包含时间段重复周期, 例如重复周期为一个月, 则下 一次允许时间段是 2011年 4月 7日 11:00至 12:00。
上述的步骤 201 是实现本发明的基础步骤, 即需要对终端的时间控制 特性信息进行初始配置。
步骤 202, 终端开机后, 发送附着请求到 MME, 其中包括终端标识和 安全证书;
步骤 203 , MME在通过对终端标识和安全证书的鉴权后 , 首先在本地 查找是否存储有时间控制特性信息, 若有则执行步骤 205; 没有时, 所述终 端的向 HSS请求该终端的签约数据;
步骤 204, HSS在收到 MME的请求后,发送终端的签约数据给 MME; 步骤 205 ,根据获取的终端的时间控制特性信息,对终端进行接入配置。 获取的终端的时间控制特性信息可以在 MME本地查找出; 也可以是 MME 获取到 HSS发送的签约数据后, 获取其中的终端的时间控制特性信息, 对 终端进行接入配置。 这里, 接入配置主要是为终端确定接入网络的通信时 间窗信息。
具体的, MME配置通信时间窗的方式如下:
首先计算允许接入时间段的时长,在本实施例中为 1个小时即 60分钟; 将时长划分为等长 10等份(具体实现, 可根据具体需要划分), 每份 时长为 6分钟, 这 6分钟时长即为终端通信时间窗的时长;
使用取随机数函数在 0至 9之间随机取一整数, 釆用下面的算法计算 通信时间窗的开始时间: 通信时间窗开始时间 =允许时间段开始时间 +随机 数 X时间窗时长。
通过随机化确定终端的通信时间窗开始时间, 可以避免终端进行通信
时因过于集中而造成的网络拥塞。
MME配置的通信时间窗参数可以有以下几种形式:
A、 通信时间窗: 开始时间, 结束时间, 或可选的包含时间段重复周期 (根据签约数据中的允许时间段来配置, 如果允许时间段配置有重复周期, 则通信时间窗也配置相同重复周期);
B、 通信时间窗: 开始时间, 时长, 或可选的包含时间段重复周期(重 复周期配置方式同 A )。
需要说明的是,如果 MME确定所接收的终端的附着请求是在允许所述 终端接入时段内时, 则以当前时刻为起点在允许所述终端接入时段内为所 述终端确定通信时间窗, 并通知该终端。
步骤 206 , MME发送附着接受消息给终端, 在附着接受消息中包含上 述为所述终端设置的通信时间窗相关参数。
步骤 207, 终端才艮据网络侧配置的通信时间窗信息, 在到达通信时间窗 开始时间时, 发送信令或数据到网络。
步骤 208, MME本地也需要保存该终端的通信时间窗信息, 并将该通 信时间窗信息发送给网关。
将上述通信时间窗信息发送网关的主要目的在于, 当终端发生异常时, 有可能会在通信时间窗以外发送信令或数据, 甚至是在签约的禁止接入时 间段内发送信令或数据, 这样, 可以针对这种异常通信状况进行差异化收 费如收取较高的通信费用, 以进一步对异常通信进行限制。
步骤 209, 网关对通信时间窗内的数据收发釆用正常的计费,对非通信 时间窗内的数据收发另行计费。
当在通信时间窗内接收到终端的数据或消息时, 正常接受该终端的数 据或消息, 网关对通信时间窗内的数据收发釆用正常的计费。 当在通信时 间窗外接收到终端的数据或消息时, 同样正常接收该终端的数据, 但是网
关对通信时间窗以外的数据收发使用较高计费。
步骤 210, 在禁止接入时间段内接收到终端的相关请求, 向终端返回接 受或拒绝消息。
需要说明的是, 终端通常被网络分配在一个跟踪区, 当终端移动出跟 踪区时, 需要通过发送跟踪去更新请求给网络, 网络在本地修改终端的跟 踪区位置信息。 同时, 当 UE不运动并且处于空闲状态时, 也需要在一个指 定的周期发送周期性的跟踪区更新请求给网络, 让网络知道终端还在线, 网络回复跟踪区更新接受给终端后, 终端开始进入下一个周期。
在禁止接入时间段内, MME接收到终端的跟踪区更新请求消息时, 接 受该终端的跟踪区更新请求, 并发送跟踪区更新接受消息给终端。
在禁止接入时间段内, MME接收到终端的附着请求消息时, 拒绝该终 端的附着请求, 发送附着拒绝消息给终端。
在禁止接入时间段内, MME接收到终端的业务请求消息时, 拒绝该终 端的业务请求, 发送业务拒绝消息给终端。
在禁止接入时间段内, MME接收到终端的分组数据网络连接请求消息 时, 拒绝该终端的分组数据网络连接请求, 发送分组数据网络连接拒绝消 息给终端。
上述的跟踪区更新接受消息, 或附着拒绝消息, 或业务拒绝消息, 或 分组数据网络连接拒绝消息中, 可以携带以下接入时间信息中的一个或多 个, 用于指示终端下一次接入的时间:
A: 通信时间窗;
B: 允许接入时间段;
C: 禁止接入时间段;
D: 延迟时间, 该延迟时间的值可以设置为等于或大于当前时间距离禁 止接入时间段结束的时间间隔。例如, 禁止接入时间段是 13: 00至 14: 00,
当前时间是 13:30, 那么发送给终端的延迟时间为 30分钟。 指示终端在 30 分钟后再发起控制消息。
步骤 211 ,终端根据所接收相关接收或拒绝消息中包含的接入时间信息 发送下一次的控制消息。 终端在接收到跟踪区更新接受消息, 或附着拒绝 消息, 或业务拒绝消息, 或分组数据网络连接拒绝消息后, 根据消息中包 含的接入时间信息发送下一次的控制消息。
需要说明的是, 上述示例中的 MME也可以是 SGSN。 上述的附着请求 也可以是跟踪区更新请求等。
实施例二
步骤 301 , 终端入网时, 终端用户将该终端签约为具有时间可控特性的
MTC终端, 并与运营商协商终端的时间控制特性信息: 允许接入时间段, 禁止接入时间段, 通信时长等。 其中允许接入时间段和禁止接入时间段这 两个时间段可以是重复出现, 也可以是单次有效。 通信时长用来指示终端 在允许接入时间段内的最大通信时长。 各时间段具体表示方式如下:
方式一:
允许接入时间段: 开始时间, 结束时间, 可选地还包含时间段重复周 期;
禁止接入时间段: 开始时间, 结束时间, 可选地还包含时间段重复周 期;
通信时长: 绝对数值, 其值不大于允许接入时间段(即结束时间减开 始时间)
示例如下:
允许接入时间段:
开始时间: 2011年 3月 7日 11:00;
结束时间: 2011年 3月 7日 12:00;
通信时长: 30分钟。
如果不包含时间段重复周期, 则表示缺省按照周期为一天 24小时重复 该时间段(则下一次允许时间段是 2011年 3月 8日 11:00至 12:00 ), 或者 表示为不重复; 如果包含时间段重复周期, 例如重复周期为一个月, 则下 一次允许时间段是 2011年 4月 7日 11:00至 12:00。
禁止接入时间段:
表示方式如上述允许接入时间段, 但是时间上要求不能和允许接入时 间段有重叠。
方式二:
允许接入时间段: 开始时间, 时长, 或可选的包含时间段重复周期; 禁止接入时间段: 开始时间, 时长, 或可选的包含时间段重复周期; 通信时长: 绝对数值, 其值不大于允许接入时间段(即结束时间减开 始时间)
示例如下:
允许接入时间段:
开始时间: 2011年 3月 7日 11:00;
允许接入时长: 1小时;
通信时长: 30分钟。
如果上述时间控制特性信息中不包含时间段重复周期, 则表示缺省按 照周期为一天 24小时重复该时间段(则下一次允许时间段是 2011年 3月 8 日 11:00至 12:00 ), 或者可以表示为不重复; 如果包含时间段重复周期, 例 如重复周期为一个月, 则下一次允许时间段是 2011年 4月 7 日 11 :00至 12:00。
步骤 302, 终端开机后, 发送附着请求到 MME, 其中包括终端标识和 安全证书;
步骤 303 , MME在通过对终端标识和安全证书的鉴权后, 首先在本地 查找是否存储有时间控制特性信息, 若有则执行步骤 305; 没有时, 所述终 端的向 HSS请求该终端的签约数据;
步骤 304, HSS在收到 MME的请求后,发送终端的签约数据给 MME; 步骤 305 ,根据获取的终端的时间控制特性信息,对终端进行接入配置。 获取的终端的时间控制特性信息可以在 MME本地查找出; 也可以是 MME 获取到 HSS发送的签约数据后, 获取其中的终端的时间控制特性信息, 对 终端进行接入配置。 这里, 接入配置主要是为终端确定接入网络的通信时 间窗信息。
MME配置通信时间窗的方式如下:
首先计算允许时间段的时长, 在本实施例中为 60分钟;
根据允许时间段的时长,将通信时间窗起始时间随机划分为 10个时刻, 许时间段时长 -通信时长)))之间的整数值, 即通信时间窗的最早起始时刻 为允许时间段的开始时间, 最晚起始时间为 (允许时间段的开始时间 + (允 许时间段时长-通信时长) ), 终端通信时间窗的时长设置为签约数据中的通 信时长;
随机划分通信时间窗的起始时刻具体方法为: 使用取随机数函数在(0 至 (允许时间段时长-通信时长))之间随机取一整数, 通信时间窗的起始时 刻 =允许时间段的开始时间 +上述算法计算的随机数。
通过随机化终端的通信时间窗开始时间, 可以避免终端开始数据收发 过于集中而造成的网络拥塞。
MME配置的通信时间窗参数可以有以下几种形式:
A、 通信时间窗: 开始时间, 结束时间, 可选地还包含时间段重复周期 (根据签约数据中的允许时间段来配置, 如果允许时间段配置有重复周期,
则通信时间窗也配置相同重复周期);
B、 通信时间窗: 开始时间, 时长, 可选地还包含时间段重复周期(重 复周期配置方式同 A )。
需要说明的是,如果 MME确定所接收的终端的附着请求是在允许所述 终端接入时段内时, 则以当前时刻为起点在允许所述终端接入时段内为所 述终端确定通信时间窗, 并通知该终端。
步骤 306, MME发送附着接受消息给终端, 在附着接受消息中包含通 信时间窗参数。
步骤 307,终端才艮据配置的通信时间窗,在到达通信时间窗开始时间时, 发送信令或数据到网络。
步骤 308, MME本地也需要保存该终端的通信时间窗信息, 并将该通 信时间窗信息发送给网关。
步骤 309, 当终端发生异常时, 有可能会在通信时间窗以外发送信令或 数据 , 甚至是在签约的禁止接入时间段内发送信令或数据。
当在通信时间窗内接收到终端的数据或消息时, 正常接受该终端的数 据或消息。
步骤 310, 在禁止接入时间段内接收到终端的相关请求, 向终端返回接 受或拒绝消息。
在通信时间窗外 (即通信时间窗之外的所有时段, 包括禁止接入时间 段), MME接收到终端的跟踪区更新请求消息时, 接受该终端的跟踪区更 新请求, 并发送跟踪区更新接受消息给终端。
在通信时间窗外, MME接收到终端的附着请求消息时, 拒绝该终端的 附着请求, 发送附着拒绝消息给终端。
在通信时间窗外, MME接收到终端的业务请求消息时, 拒绝该终端的 业务请求, 发送业务拒绝消息给终端。
在通信时间窗外 , MME接收到终端的分组数据网络连接请求消息时 , 拒绝该终端的分组数据网络连接请求, 发送分组数据网络连接拒绝消息给 终端。
在跟踪区更新接受消息, 或附着拒绝消息, 或业务拒绝消息, 或分组 数据网络连接拒绝消息中, 可以携带以下接入时间信息, 用于指示终端下 一次接入的时间: 通信时间窗。
步骤 311 ,终端根据所接收相关接收或拒绝消息中包含的接入时间信息 发送下一次的控制消息。 终端在接收到跟踪区更新接受消息, 或附着拒绝 消息, 或业务拒绝消息, 或分组数据网络连接拒绝消息后, 根据消息中包 含的接入时间信息发送下一次的控制消息。
需要说明的是, 上述示例中的 MME也可以是 SGSN。 上述的附着请求 也可以是跟踪区更新请求等。
