分组交换业务小区更新时的终端和网络的异常处理方法
摘要：
本发明公开了分组交换业务小区更新时的终端和网络的异常处理方法，解决由于本地Qos处理不一致而导致的PS业务中断。其技术方案为：(1)通过明确约束SGSN在Qos没有变化的情况下，如果收到终端的Modify？PDP？context？Request消息，不进行与GGSN的Update？PDP？Context过程，直接响应终端Modify？PDPContext？Accept消息的行为，达到恢复PS业务的目的；(2)通过终端的自主行为，即当终端发出Modify？PDP？context？request消息后，如果发现PS业务的RAB已经正常建立，则终止当前Modify？PDP？context过程，并立即恢复最大比特速率，达到恢复PS业务的目的。本发明应用于移动通信领域。
摘要（英）：

The invention discloses an abnormal processing method for a terminal and a network for packet switching service district refreshment, which solves the problems of PS service interruption caused by non-conforming local Qos processing. The method comprises the steps of: (1) under the condition that a service GPRS supporting node (SGSN) is clearly restricted to have no Qos change, if the Modify PDP context Request message at the terminal is received, directly responding the Modify PDP Context Accept message at the terminal without carrying out the Update PDP Context process with the GGSN to achieve the purpose for restoring PS service; and (2) after the terminal sends the Modify PDP context request message, if the RAB of the PS service is found to be normally established, terminating the current Modify PDP context process by the autonomic activity of the terminal, and restoring the maximum bit rate immediately to achieve the purpose for restoring PS service. The invention is applied to the mobile communication field.
