具体实施方式
在本发明实施例中，网络实体根据外部应用的注册表创建请求创建并保存与外部应用身份信息对应的注册表，并根据MTC设备的注册请求信息，将MTC设备的身份信息添加到对应的注册表中，从而可以在接收到外部应用发送的获取MTC设备信息的请求消息时，在确定与外部应用身份信息对应的注册表中包含该MTC设备的身份信息时，将该获取MTC设备信息的请求消息转发至MTC设备，以使MTC设备将MTC设备信息发送给外部应用。如此，使得网络实体可以直接处理外部应用获取MTC设备信息的请求，有效降低网络信令流量，从而有效减少网络拥塞的发生。
图1为本发明实施例一提供的MTC设备信息获取方法的流程图。如图1所示，本实施例提供的方法可以包括：
步骤101、网络实体接收外部应用发送的获取MTC设备信息的请求消息；所述请求消息中包含外部应用身份信息和MTC设备身份信息。
步骤102、所述网络实体在对所述外部应用认证通过后，查询与所述外 部应用身份信息对应的注册表中是否包含所述请求消息中的MTC设备身份信息。
步骤103、所述网络实体在所述注册表中包含所述请求消息中的MTC设备身份信息时，将所述请求消息转发至与所述MTC设备身份信息对应的MTC设备。
外部应用在需要获取特定MTC设备信息时，通过SCEF向网络实体发送用于获取MTC设备信息的请求消息，所述请求消息中包含外部应用身份信息以及与要获取的MTC设备信息对应的MTC设备身份信息；网络实体首先认证该外部应用，在认证通过后，根据所述请求消息中的外部应用身份信息，查询与所述外部应用身份信息对应的注册表，判断注册表中是否包含请求消息中的MTC设备身份信息；如果所述注册表中包含请求消息中的MTC设备身份信息，则所述网络实体转发所述外部应用发送的所述请求消息给对应的MTC设备；所述MTC设备接收到所述请求消息后，通过SCEF向所述外部应用反馈MTC设备信息；如果所述注册表中未包含所述请求消息中的MTC设备身份信息，则所述网络实体通过SCEF向所述外部应用发送拒绝响应消息，拒绝所述外部应用获取所述MTC设备信息。
需要说明的是，所述网络实体对外部应用、对MTC设备以及对注册请求的相关认证过程与现有技术相同，本实施例只使用认证结果，即在认证通过后执行后续步骤，具体的认证过程在此不再赘述。
在一实施例中，所述网络实体中注册表的建立是由所述外部应用发起的，图2为本发明实施例一提供的MTC设备信息获取方法中网络实体创建注册表的流程图。如图2所示，网络实体创建注册表的过程包括：
步骤201、所述网络实体接收所述外部应用发送的注册表创建请求消息；所述注册表创建请求消息中包含所述外部应用的外部应用身份信息；
步骤202、所述网络实体在对所述外部应用认证通过后，根据所述注册 表创建请求消息，创建并存储与所述外部应用身份信息对应的注册表。
所述网络实体接收到注册表创建请求消息后，首先需要对所述外部应用进行认证，认证通过后，以所述注册表创建请求消息中包含的所述外部应用身份信息创建一个注册表，该注册表由MTC设备身份信息构成，其中，注册表中的MTC设备身份信息是由MTC设备在所述网络实体上注册后获得的。
需要说明的是，当所述注册表为空表时，表示所述注册表所属的外部应用不能获取任何MTC设备的MTC设备信息。
在步骤202之后，所述网络实体可以根据需要向所述外部应用发送注册表创建确认信息，本实施例对此不做具体限定。
在一实施例中，所述MTC设备在所述网络实体中注册是由MTC设备主动发起的，图3为本发明实施例一提供的MTC设备信息获取方法中MTC设备在网络实体上注册的流程图。如图3所示，所述MTC设备在所述网络实体的注册过程可以包括：
步骤301、所述网络实体接收所述MTC设备发送的注册请求信息，所述注册请求信息中包含所述MTC设备的身份信息和外部应用身份信息；
步骤302、所述网络实体在所述注册请求信息验证通过后，将所述MTC设备的身份信息添加至与所述外部应用身份信息对应的注册表中；
步骤303、所述网络实体向所述MTC设备发送注册确认信息。
在一实施例中，从所述网络实体是注册表中删除MTC设备身份信息的过程如图4所示，可以包括：
步骤401、所述网络实体接收所述MTC设备发送的删除请求消息；所述删除请求消息中包含所述外部应用身份信息和待删除MTC设备身份信息；
步骤402、所述网络实体在对所述MTC设备验证通过后，从与所述外 部应用身份信息对应的注册表中，删除所述待删除MTC设备身份信息；
步骤403、所述网络实体向所述MTC设备发送删除确认信息。
本实施例的技术方案，可以使网络实体直接处理外部应用获取MTC设备信息的请求，有效降低网络信令流量，从而有效减少网络拥塞的发生。
图5为本发明实施例二提供的MTC设备信息获取方法的流程图。如图5所示，本实施例提供的方法包括：
步骤501、MTC设备接收网络实体发送的请求消息，所述请求消息中包含外部应用身份信息和MTC设备身份信息。
在本步骤之前，所述MTC设备将自身的身份信息注册到所述网络实体上指定的外部应用的注册表中，表明允许该注册表对应的外部应用获取自己的MTC设备信息。
所述MTC设备向所述网络实体发送注册请求信息，所述注册请求信息中包含所述MTC设备的身份信息和外部应用身份信息；所述MTC设备接收所述网络实体发送的注册确认信息。
步骤502、所述MTC设备根据所述请求消息，将所述MTC设备信息发送给与所述外部应用身份信息对应的外部应用。
当所述MTC设备不允许某注册表对应的外部应用获取自己的MTC设备信息时，需要从所述网络实体上删除注册表中的MTC设备身份信息。
所述MTC设备向所述网络实体发送删除请求消息；所述删除请求消息中包含所述外部应用身份信息和待删除MTC设备身份信息；所述MTC设备接收所述网络实体发送的删除确认信息。
本实施例的技术方案，可以有效降低网络信令流量，从而有效减少网络拥塞的发生。

步骤601、外部应用向网络实体发送获取MTC设备信息的请求消息；所述请求消息中包含外部应用身份信息和MTC设备身份信息；
步骤602、所述外部应用接收所述MTC设备发送的所述MTC设备信息。
外部应用需要在所述网络实体中创建与自身对应的注册表，所述注册表由MTC设备身份信息构成，其中，所述注册表中的MTC设备身份信息是由MTC设备自身发起注册后添加至所述注册表中的，可以参照上述图5所示方法实施例，此处不再赘述。
所述外部应用向所述网络实体发送注册表创建请求消息；所述注册表创建请求消息中包含所述外部应用的外部应用身份信息；在所述网络实体有需要时，还会向所述外部应用发送注册表创建确认信息，此时，所述外部应用接收所述网络实体发送的注册表创建确认信息。
本实施例的技术方案，可以有效降低网络信令流量，从而有效减少网络拥塞的发生。
