State simultaneously resets the modem simultaneously.
Specifically, default protocol stack is one in multiple protocol stacks that modem is supported, it is pre-set association
Stack is discussed, can the association that the protocol stack of the same acquiescence is used as modem initial selected be set for all regions herein
Stack is discussed, single area can also be directed to or different default protocol stacks, this hair are respectively set in some region of multiple areas
Bright embodiment is not limited in any way.Wherein, a kind of feasible embodiment is：It can be with each agreement of Premises modem
The priority level of stack, such as：The priority level of each protocol stack can be set when modem dispatches from the factory；Alternatively, can be with
During in modem is configured in mobile terminal and initialization, each protocol stack is used according to mobile terminal
When network connection and network signal intensity situation be arranged priority level；Etc..Another feasible embodiment is：It can be with
The priority level of each protocol stack of modem is adjusted flexibly, such as：It can be according to mobile terminal in some band of position
Priority level is arranged in network connection and network signal intensity situation when using each protocol stack；Alternatively, can be according to mobile whole
The priority level of each protocol stack is arranged in the sequence of the common network formats at end；It waits for.It should be noted that some protocol stack
Priority level is higher, illustrates that mobile terminal is based on the protocol stack and can obtain better network connection or stronger network signal.
The highest protocol stack of priority level is commonly known as default protocol stack in modem, and modem be generally also according to
Priority level realizes the network registry and Web vector graphic of mobile terminal from high to low sequence using each protocol stack.
If registering upper network not successfully using second protocol stack, modem is according to previously known default protocol stack
On off state restores default protocol stack switch state or carries out reset operation to modem simultaneously.After resetting operation, adjust
Modulator-demodulator is worked using default protocol stack.It is understood that default protocol stack herein both may be the first agreement
Stack, it is also possible to other protocol stacks other than the first protocol stack.It should be noted that if default protocol stack is the in the present embodiment
One protocol stack (protocol stack that is i.e. pent, causing dedicated bearer processing generation exception), then, this step is equivalent to again
Open the first protocol stack.
Implement the embodiment of the present invention, modem detects abnormal caused by currently used protocol stack crashes and true
