具体实施方式
以下结合说明书附图对本公开的示例性实施例进行说明，应当理解，此处所描述的示例性实施例仅用于说明和解释本公开，并不用于限定本公开。
本公开提供一种基于MME的用户数据存储方法，通过将原本存储于MME中的用户数据存储到HSS(Home Subscriber Server，归属签约用户服务器)或其他预置存储设备，当MME接收到下行报文或者上行报文时，则从该HSS或预置存储设备中获取所述用户数据，然后再按照标准的寻呼流程进行数据传输，从而解决了MME存储用户数据的容量非常有限的问题。
参照图1，图1为本公开基于MME的用户数据存储方法第一示例的流程示意图，本示例中，所述基于MME的用户数据存储方法包括：
步骤S10，MME在接收到S1接口释放的用户数据之后，将所述用户数据存储到HSS或预置存储设备。
其中，参照图2，图2为本公开中基于MME的用户数据传输过程示意图，在图2中：
步骤11表示如果基站eNodeB检测发现需要与UE断开信令连接和所有的无线承载，eNode会向MME发送“S1UE Context Release Request”消息，即向MME发送用户上下文释放请求消息，并且包含释放原因。
步骤12表示MME发送“Release Access Bearers Request”消息到SGW，请求释放所有和UE相关的S1-U承载。此消息既可以由从eNodeB发来的S1Release Request消息触发，也可以由MME的其他事件触发。
步骤13表示SGW释放所有eNodeB相关于UE的信息，并且向MME返回“Release Access Bearers Response”消息，SGW上下文其他的元素则不受影响。
步骤14表示MME通过向eNodeB发送S1UE上下文释放命令消息来释放S1。
步骤15表示如果RRC连接已经释放，eNodeB会发送“RRC Connection Release”消息到UE。
步骤16表示eNodeB通过向MME发送“S1UE Context Release Complete”消息确认S1接口完成释放。通过此消息UE在MME和eNodeB 间的信令连接被断开。
本示例中，在上述步骤16之后，MME会接收到S1接口释放的用户数据，此时，MME则将接收到的该用户数据存储到HSS或预置存储设备。其中，预置存储设备包括如RAM、ROM等电能存储设备，或者如硬盘、磁带、磁芯存储器等磁能存储设备等。

步骤18表示HSS或预置存储设备在接收到所述数据存储请求消息后，则存储所述用户数据，并向MME发送相应的反馈消息；
其中，MME在接收到HSS或预置存储设备发送的反馈消息之后，删除接收到的所述用户数据，从而保证了MME的正常工作。
