M2M系统架构中，机器类型通信 ( Machine Type Communications, MTC ) 设备 ( Device )通过移动运营商网络（ MNO )连接到 MTC服务器（ Server ), MTC服务器向 MTC用户 （ User )提供 M2M业务。
移动运营商网络（MNO )可以是 LTE网络中的无线演进网络。 无线演进 网络的核心网主要包含 MME、 服务网关 （Serving Gateway, S-GW)、 PDN Gateway(P-GW)三个逻辑功能体，其中的移动管理实体（ Mobility Management Entity, MME), 负责非接入层 ( Non-access layer, NAS )信令和 NAS信令加 密以及漫游、 跟踪等功能， 分配用户临时身份标识、 安全功能等， 它对应于 当前 UMTS系统内部 SGSN的控制平面部分。 S-GW负责本地的移动性锚点 和 3GPP系统内部的移动性锚点以及合法监听相关信息； P-GW则负责策略执 行和计费以及合法监听相关功能。
当无线环境中放置有干扰机（Phonejammer )时， 终端与无线基站之间的 正常通信将受到干扰。
现有技术中， MTC设备通过自检功能确认当前是否处于干扰的环境中， 并通过移动网络运营商 （MNO )将正处于被干扰状态的信息通知给 MTC服 务器， 以确保 M2M应用的安全可靠性。
如果干扰信号足够强大，则 MTC设备无法与网络通信，从而无法将正处 于被干扰状态的信息通知给 MTC服务器。 发明内容

步骤 11、 接收接入网网元发送的当前被干扰的区域位置信息；
其中， 接入网网元可为基站子系统（Base Station Subsystem, BSS )、 无 线网络控制器（ Radio Network Controller, RNC )、 演进基站 （ eNodeB )等。 例如， eNodeB执行干扰监测， 发现有干扰的时候， 发送消息 （例如， Notify Request )给 MME , 消息中携带 "Jamming Indication" -用于指示当前无线 环境存在干扰， 另外消息中携带对应的被干扰的区域位置信息。
接入网网元对当前的无线环境进行干扰监测。 具体地， 例如接入网网元 通过对接收的信号进行误码率、 发射功率等分析， 定位所控制的无线环境中 是否存在干扰。 如接入网元对某一区域发送或者接收的信号进行分析， 如果 误码率超过设定的值， 则可以确定该区域受到了干扰。 进一步， 接入网网元 可以定位到当前被干扰的区域位置信息。区域位置信息的具体形式可以是： a ) 通信网络规划的区信息如小区全球标识 ( Cell Global Identification, CGI ), E-UTRAN小区全球标识（E-UTRAN Cell Global Identifier, ECGI )、 路由区 域标识 ( Routeing Area Identity, RAI )、跟踪区域标识 ( Tracking Area Identity, TAI )等， 表示当前哪些小区、 路由区、 跟踪区等受到干扰； b )具体的物理 位置信息， 如被干扰区域的经度、 纬度等， 表示当前哪些具体的物理位置区 域受到干扰。 区域位置信息也可以是其它表现方式， 这里不做限定。

例如， eNodeB执行干扰监测， 发现有干扰的时候， 发送消息 （例如， Notify Request )给 MME , 消息中携带 "Jamming Indication"用于指示当前无 线环境存在干扰， 另外消息中携带对应的被干扰的区域位置信息。
其中， 核心网网元可为 GPRS 服务支持节点 （Servicing GPRS Support Node, SGSN )、 MME等。

当上述步骤 11、 步骤 12由 MTC服务器执行时， 上述步骤 11可包括： MTC服务器通过核心网网元接收接入网网元发送的当前被干扰的区域位置 信息。
接入网网元执行监测并发送当前被干扰的区域位置信息的行为可以是本 地配置， 例如， 接入网网元缺省具有监测干扰并向核心网网元发送当前被干 扰的区域位置信息的功能； 另外， 所述行为也可以受核心网网元的事件订阅 的触发来进行， 例如， 核心网网元发送消息要求接入网网元监测到无线环境 存在干扰时， 发送被干扰的区域位置信息。
当接入网网元受核心网网元的事件订阅执行监测并发送当前被干扰的区 域位置信息时， 步骤 11之前还可包括：
核心网网元向所述接入网网元发起请求， 以触发所述接入网网元发送当 前被干扰的区域位置信息。 具体地， 核心网网元可向所述接入网网元发起用 于获取区信息形式或物理位置信息形式的当前被干扰的区域位置信息的请 求。
核心网网元可缺省具有根据被干扰的区域位置信息匹配出处于被干扰状 态的 MTC设备，将所述 MTC设备被干扰的信息发送给 MTC服务器的功能； 或者可缺省具有将所述当前被干扰的区域位置信息发送给 MTC服务器的功 能，之后 MTC服务器便可根据被干扰的区域位置信息匹配出处于被干扰状态 的 MTC设备。
另外，核心网网元也可根据 MTC设备的签约数据中包含的干扰检测的特 性， 将接收到的接入网网元提供的被干扰的区域位置信息匹配出处于被干扰 状态的 MTC设备， 再将所述 MTC设备被干扰的信息发送给 MTC服务器； 或者将所述当前被干扰的区域位置信息发送给 MTC服务器， 之后 MTC服务 器便可根据当前被干扰的区域位置信息匹配出处于被干扰状态的 MTC设备。 所述签约数据包含干扰监测的特性。

图 6为本发明实施例提供的另一种干扰监测的方法的信令流程图。 本实 施例为某一 MTC设备接入 LTE网络的一个具体实施例。 如图 6所示 , 该干 扰 MTC设备的处理流程包括：
步骤 61 : eNodeB开始工作时， MME向 eNodeB订阅干扰监测事件。 具 体的， eNodeB向 MME发送 "SI SETUP REQUEST" 消息， 请求开始工作。 MME向 eNodeB返回 "SI SETUP RESPONSE" 消息。 MME可根据预先的设 置， 需要触发 eNodeB检测干扰事件， 如 "SI SETUP RESPONSE" 消息中 MME向 eNodeB订阅干扰监测事件， 使 eNodeB将监测到的当前被干扰的区 域位置信息发送给 MME。 例如， 消息中携带信元 "Jamming Required" -用 于订阅干扰监测事件， 使 eNodeB将监测到的当前被干扰的区域位置发送给 MME。 进一步的， "SI SETUP RESPONSE" 消息中可以指示当前被干扰的区 域位置发送的粒度即被干扰的区域位置信息的表现形式。 例如， 基于 ECGI, 基于 TAI或者基于具体物理位置（经纬度）等等。
步骤 62: MTC设备接入 LTE网络， MTC设备通过 eNodeB发送注册请 求例如附着请求 ( Attach Request )给 MME;
步骤 63: MME与 HSS交互， 获取 MTC设备的签约数据。
若 MTC User ( MTC用户 )对其所属的 MTC设备有干扰监测的需求， MTC User可首先向运营商订阅干扰监测即将干扰信息发送 MTC服务器。 订 阅后， 干扰监测的订阅信息存储在 HSS上 MTC设备的签约数据中。
干扰监测的订阅信息的表现形式可以是在 MTC设备的签约数据中配置 需要网络对其执行干扰监测的标记 , 如配置 " MTC Feature-Jamming Indication"。
后续 MME从 HSS获得 MTC设备的签约数据，若其中包含" MTC Feature - Jamming Indication" , 则 MME需要对此 MTC设备执行干扰监测 , 具体地， MME通过接收接入网网元提供的当前被干扰的区域位置信息匹配出处于被 干扰状态的 MTC设备，将所述 MTC设备被干扰的信息发送给 MTC服务器， 或者将所述当前被干扰的区域位置信息发送给 MTC服务器。
干扰监测的订阅信息的表现形式也可以是在群组（MTC Group )签约数 据中配置需要网络执行干扰监测的标记。例如，在群组签约数据中配置 "MTC Feature-Jamming Indication"。
后续 MME获得群组签约数据， 若群组签约数据中包含 "MTC Feature - Jamming Indication" ,则 MME需要对此群组执行干扰监测。具体地， 当 MME 确认网络中存在干扰时，及时通知 MTC服务器某具体区域位置存在干扰。标 记中可以指示干扰监测事件发送的粒度即区域位置信息的表现形式， 例如， 基于 ECGI、 基于 TAI或者基于具体物理位置（经纬度）等等。
另夕卜，若步骤 61中 MME未向 eNodeB订阅干扰监测事件，则此时 MME 还可以向 eNodeB 订阅干扰监测事件。 例如 , MME 发送 " MME CONFIGURATION UPDATE" 消息给 eNodeB , "MME CONFIGURATION UPDATE" 消息中 MME向 eNodeB订阅干扰监测事件。 例如， 消息中携带信 元 "Jamming Required" -用于订阅干扰监测事件， 使 eNodeB将监测到的当 前被干扰的区域位置信息发送给 MME。进一步的， "MME CONFIGURATION UPDATE" 消息中可以指示干扰监测事件发送的粒度即区域位置信息的表现 形式， 例如， 基于 ECGI、 基于 TAI或者基于具体物理位置 （经纬度）等等。
另外， 签约数据中还可以配置与干扰监测事件发送相关的信息， 例如， 干扰监测事件需要发送的 MTC服务器地址信息。
由于干扰监测并非所有 M2M应用的需求， 且干扰监测会额外的消耗网 络资源， 因此可以基于干扰监测事件进行特定计费。
步骤 64: MME向 UE返回注册响应例如附着接受 ( Attach Accept )。 步骤 65: eNodeB对所属无线环境进行监测， 当 eNodeB确认无线环境存 在干扰时， 基于 MME的干扰监测事件订阅或者根据自身缺省配置， eNodeB 向 MME通知干扰。例如 , eNodeB发送" JAMMING INDICATIOAN或者 Notify Request" 消息给 MME, 告知当前无线环境中发生干扰。 例如， 消息中携带 "Jamming Indication" -用于指示当前无线环境存在干扰， 另外消息中携带 对应的当前被干扰的区域位置信息。 特别的， eNodeB可以在确认当前干扰足 以影响 MTC设备与网络的正常通信如 MTC设备已经无法接入网络， 即当前 干扰不可控的情况下， 向 MME通知干扰。 "JAMMING INDICATIOAN" 消 息中可携带发生干扰的区域位置信息如被干扰的基于 ECGI、 TAI或者具体物 理位置 (经纬度 )等等。 所述区域位置信息的粒度即表现形式可以根据 MME 的订阅或者 eNodeB缺省配置。
进一步地，当干扰被消除时， eNodeB还可以向 MME发送干扰消除信息。 例如， eNodeB发送 "JAMMING CLEAR INDICATIOAN或者 Notify Request" 消息给 MME , 告知当前无线环境中干扰已消除。 "JAMMING CLEAR INDICATIOAN或者 Notify Request" 消息中携带以消除干扰的区域位置信息 如被干扰的基于 ECGI、 TAI或者具体物理位置（经纬度）等等。 所述区域位 置信息发送的粒度可以根据 MME的订阅或者 eNodeB缺省配置。
步骤 66: MME接收 eNodeB发送的当前被干扰的区域位置信息，根据步 骤 63的描述， 确认需要执行干扰监测， 并进行处理。
当上述步骤 63中 MTC User订阅干扰监测的方式是在 MTC设备的签约 数据中配置需要网络对其执行干扰监测时， 干扰信息的处理方法包括：
步骤 66a: MME根据当前被干扰的区域位置信息匹配出处于被干扰状态 的 MTC设备。 例如， 通过查找保存的 MTC设备的上下文， 若当前被干扰区 域属于或者包含于当前 MTC设备的有效服务区域，则确认 MTC设备被干扰。
本发明实施例提供的干扰监测的方法适合位置比较固定的 MTC设备。 对于位置比较固定的 MTC设备 , MME比较容易确认 MTC设备是否属 于当前被干扰区域。 MME获取 MTC设备相对固定位置信息的方法有两种： 第一种方法根据一种位置较固定的 MTC设备，其位置信息可以作为签约 数据， 当 MME从 HSS获得 MTC设备的签约数据， 也就获得了 MTC设备的 位置信息， 并将其保存在上下文中。 一般都是 ECGI的粒度。
第二种方法根据位置较固定的 MTC设备可以在其签约数据中配置相应 的特性， 例如， MTC Feature配置为 "Low Mobility"。 MTC设备发起附着流 程， MME从 HSS获得 MTC设备的签约数据， 也就获得了 MTC设备具有较 固定位置信息的特性。 如 MTC设备执行附着流程 ( Attach procedure ) 时， eNodeB将会向 MME提供设备当前所处的 ECGI, MME将当前 MTC设备所 处位置信息作为此 MTC设备的缺省位置信息保存在其上下文中。
若确认被干扰的 MTC设备同时订阅了干扰监测， 则 MME需要将 MTC 设备处于干扰状态的信息告知对应的 MTC服务器。 另外 , 对于确认被干扰的 MTC设备， ΜΜΕ可以将其设置为干扰状态 , 例如，在其上下文中设置标记位" JAMMING FLAG"。对于确认被干扰的 MTC 设备， 后续 MME接收到相应的下行数据或者信令的事件将不会触发下行寻 呼消息， 因为干扰的存在， 网络侧无法与 MTC设备进行通信。 一旦干扰解除 如 MME接收到 eNodeB发送的 "JAMMING CLEAR INDICATIOAN" 消息 , 则 MME可以清除已设置的干扰终端， 此时 MTC设备恢复正常， 可以节省有 效的网络资源。 这样的寻呼优化同样比较适合于位置较固定， 即 "Low Mobility" 类型的 MTC设备。
步骤 66b: MME将 MTC设备正处于被干扰状态的信息直接传递给 MTC 服务器。例如， MME发送" Jamming Indication"消息给 MTC服务器， "Jamming Indication"消息中携带用于标识正处于被干扰状态的 MTC设备的标识信息； 或者通过第三网元如 HSS、 GGSN、 P-GW等将 MTC设备正处于被干扰状态 的信息传递给 MTC服务器。
当上述步骤 63中 MTC User订阅干扰监测的方式也可以是在群组签约数 据中配置需要网络执行干扰监测时， 干扰监测事件的处理方法包括：
步骤 66c: MME将 eNodeB发送的干扰信息转发给 MTC服务器。 MME 通过上下文确认订阅干扰监测的群组， 并将 eNodeB发送的当前被干扰的区 域位置信息转发给对应的 MTC 服务器。 例如， MME 发送 "Jamming Indication" 消息给 MTC 服务器， 消息中还需携带群组的标识信息； 或者 MME通过第三网元如 HSS、 GGSN、 P-GW等将 eNodeB发送的干扰信息传 递给 MTC服务器。
步骤 66d: MTC服务器根据当前被干扰的区域位置信息匹配出处于被干 扰状态的 MTC设备。 例如， MTC服务器可以根据 MTC设备的上下文和当 前被干扰得区域位置信息匹配出处于被干扰状态的 MTC设备。 进一步的， MTC服务器可以对处于干扰状态的 MTC设备进行相应的检测处理。
上述实施例中， 接入网网元对无线环境进行干扰监测， 并将监测到的被 干扰的区域位置信息通知核心网网元， 核心网网元根据接收到的被干扰的区 域位置信息匹配找到被干扰的 MTC设备，并将正处于被干扰状态的信息通知 MTC服务器；或者将当前被干扰的区域位置信息发送给 MTC Serve之后 MTC 服务器便可根据当前被干扰的区域位置信息匹配出处于被干扰状态的 MTC 设备， 实现了干扰信号导致 MTC设备无法与网络通信的情况下，将正处于被 干扰状态的信息通知给 MTC服务器， 提高了 M2M应用的安全性。
