Abstract

The invention discloses a network parameter recovery apparatus and a method thereof. When the apparatus and the method are applied in a whole Netcom mobile terminal, an application program side decides whether parameter synchronization loading needs to be performed when the mobile terminal is switched on every time, in a factory data reset state or in an updating state and in other scenes. If the parameter synchronization loading is needed, a network parameter file stored in the application program side is reloaded to a modem side so as to complete parameter synchronization. The modem side detects a parameter abnormity event. And when an abnormal event is generated, the parameter abnormity event is sent to the application program side. The application program side decides and determines whether parameter abnormity recovery needs to be performed based on the network parameter file of dual memory. When the parameter abnormity recovery needs to be performed, the network parameter file stored in the application program side is reloaded to the modem side so as to replace the abnormal network parameter file. Network parameter recovery is performed on the network parameter file based on dual memory when the parameter recovery is needed so that stability of the mobile terminal can be increased.
