Description

一种核心网网元处理终端注册拥塞的方法及装置 技术领域
本申请涉及但不限于IT(Information Technology，信息技术)和CT(Cloud terminal，云终端)终端与服务器通讯技术领域，尤其涉及一种核心网网元处理终端注册拥塞的方法及装置。
背景技术
在一些场景下会出现终端注册拥塞的情况，例如核心网设备升级或因其他原因发生服务中断、核心网设备重新启动、承载网发生故障导致终端跟核心网连接较长时间中断等，这些情况下都需要终端重新注册。
因为是核心网侧发生中断，众多的终端都是正常并在线的，一旦核心网元恢复，所有终端注册请求将蜂拥而至，形成注册波峰，超出核心网网元的正常处理能力，造成拥塞，并最终形成注册雪崩。
对于注册拥塞场景下接收上来的注册报文，相关技术主要有：
技术1：对接收到的所有注册请求，进行正常的注册业务处理后，转发至后续网元处理。此技术的缺点是：在注册拥塞的情况下，核心网网元接收的注册请求的流量是超负荷的，进行正常处理并转发到后续网元，后续响应消息将接踵而至，会导致核心网网元更加繁忙，进而陷入恶性循环，形成注册雪崩。
技术2：对接收到的所有注册请求，一部分正常处理，另一部分给终端注册请求回拒绝消息或错误消息。此技术的缺点是：终端接收拒绝或错误消息后，通常会立即再次发起重新注册请求，这些重注册请求会立即再次拥塞核心网网元。
技术3：对接收到的所有注册请求，一部分正常处理，另一部分做丢弃处理。此技术的缺点是：做丢弃处理的注册请求，终端会进行更多次的重传和重新注册，更加大了雪崩规模。

步骤23：基于步骤22，SBC可以在200OK中通过设置对不同的终端设置不同的expire值(注册刷新周期)，将终端的再次发起重注册消息的时间进行离散，这样能取得更好的流量整形的效果。
本发明实施例方案通过对蜂拥而至的终端注册流进行流量整形，迅速降低注册流量波峰，避免注册雪崩的出现，达到了很好缓解注册拥塞的效果，节省了核心网网元恢复服务的时间，提高了核心网网元的可用性等。
