Description
Technical field：
The invention belongs to computer modularized administrative skill fields, and in particular to a kind of module management sides 4G based on state machine
Method.
Background technology：
In the design of early stage, module status definition is roughly classified into INIT_DO（No initializtion）, INIT_DOING（It is initial
Change）, INIT_DONE（Initialization is completed）, INIT_UPDATE（Configuration update）,INIT_RESET（Restart）Five states.It deposits
In following disadvantage：
1. without distinguishing the mode of reset modules, reset management is not fine enough.Reset modules can be divided into actual use
Soft reboot (softreset) and restart (hardreset) firmly.Soft reboot module speed is fast, can solve most of software issue.
Restarting mode firmly can power off and re-power to module, can repair the indeterminable problem of soft reboot.
2. after the completion of module initialization, not defining " CALL, TTS " working condition.To module under INIT_DONE states
Part operation or part AT instruction phone can be caused surprisingly to hang up, TTS report it is abnormal.
3.INIT_DO, INIT_UPDATE state are not necessarily to.Under INIT_DO states, module is to event without response.
INIT_UPDATE states are to configure to design for update module, are also unnecessary in actual use.
Invention content：
For existing defect and problem under each state during current modularization management, the present invention provides a kind of based on state machine
4G module management methods.
Scheme is used by the present invention solves its technical problem：A kind of 4G module management methods based on state machine,
In existing 4G module basis, a state machine is devised（Finite State Machine）, and 4G is managed with this state machine
The work of module, the state machine redesign the working condition of 4g modules, define under each state the event that may occur and
The corresponding processing action of the event.And module management relative program is instructed to design with this state machine；Again module in design
Working condition has：Initing states, Normal states, Call/TTS states, SoftRest states and HardReset states；
Call/tts particular job states are divided out from normal operating conditions again, unnecessary module is not handled under this state and matches
It sets and inquiry instruction.
Under module normal operating conditions, if configuration change or module itself are abnormal, need to jump to Initing states,
And increase SoftReset states（Soft reboot state）With HardReset states（Hard rebooting status）.
The Initing states：Meet module on hardware and normally start requirement, software upper module is not yet completed to initialize.
Management program can only execute R or I under this state（Recognize or Init）Action.If the action runs succeeded, module
Enter Normal states.If the action executes failure, module jumps to HardReset states.
The Normal states：Module can work normally, and the action that module management program can execute under this state has
Module is arranged（Search net pattern, volume setting, APN settings etc.）.Status inquiry（Network registry state, sim card informations etc.）.It connects
It makes a phone call or TTS is reported（The action lower module will jump to CALL/TTS working conditions）.
If the work of 4G modules is abnormal or necessary configuration updates, make module jump to SoftReset states or
HardReset states.
The Call/tts states：Under the state, the unnecessary operations to module should be stopped（Prevent phone from being hung extremely
It is disconnected）.And follow-up call or TTS business progresses.When service ending, Normal states are immediately hopped to.
The SoftReset states：Module repeatedly returns to ERROR, registration abnormity, and the events such as configuration update can lead to mould
Block jumps to SoftReset states.Under the state, module is removed error and is counted, and is jumped to after executing soft reboot operation
Initing states.
The HardReset states：When fatal error or soft reboot cannot solve the problems, such as, module can jump to
HardReset states.Under the state, module is removed error and is counted, and hard reboot operation is executed（To module power down and power on）After jump
Go to initing states.
Beneficial effects of the present invention：
1. the management module in a manner of state machine, more conducively tutorial program design, module status transition process is apparent.
2. reset module machines are distinguished soft reboot (softreset) and are restarted (hardreset) firmly.Soft reboot module
Speed is fast, can solve most of software issue.Restarting mode firmly can power off and re-power to module, can repair soft reboot
Indeterminable problem.
3. defining " CALL, TTS " working condition.Under this state, it is not responding to unnecessary configuration and inquiry instruction, is avoided
Phone is surprisingly hung up, and TTS reports abnormal.
Description of the drawings：
Fig. 1 is state machine work and state transition design sketch in the present invention.
Specific implementation mode：
Present invention will be further explained below with reference to the attached drawings and examples.
Devise a state machine（Finite State Machine）, and with this state machine manage 4G modules work,
The state machine redesigns the working condition of 4g modules, defines the event that may occur under each state and the event is corresponding
Processing acts.And module management relative program is instructed to design with this state machine.Again there is the working condition of module in design：
Initing states, Normal states, Call/TTS states, SoftRest states and HardReset states；Initing states are negative
Blame the initialization of module；Normal states are the normal operating conditions of module；CALL/TTS states are particular job shapes of module
State does not handle unnecessary module configuration and inquiry instruction, is interrupted accidentally to avoid phone or tts broadcastings under this state.
SoftReset states are responsible for the soft reboot of module, and HardReset states are responsible for restarting firmly for module.4G modules can be simply
It is divided into normal operating conditions and init state.In view of make a phone call or TTS playing process in, part operation can cause phone different
It often hangs up, so dividing out CALL/TTS particular job states from normal operating conditions, does not handle under this state unnecessary
Module configures and inquiry instruction.Under module normal operating conditions, configuration change or module itself are abnormal, need to jump to
INITING states increase soft reboot state and hard rebooting status.
As shown in Figure 1：
（1）Initing states (are initializing)：Meet module on hardware and normally start requirement, software upper module is not yet completed
Initialization.Management program can only execute R or I under this state（Recognize or Init）Action.The action runs succeeded, mould
Block enters Normal states.The action executes failure, and module jumps to HardReset states.
（2）Normal states：Module can work normally, and the action that module management program can execute under this state has mould
Block is arranged（Search net pattern, volume setting, APN settings etc.）；Status inquiry（Network registry state, sim card informations etc.）；It takes
Phone or TTS are reported（The action lower module will jump to CALL/TTS working conditions）.Module work is abnormal or necessary matches
Update is set, module can be made to jump to SoftReset states or HardReset states.
（3）Call, tts state：Under the state, the unnecessary operations to module should be stopped（Prevent phone from being hung extremely
It is disconnected）.And follow-up call or TTS business progresses.When service ending, normal states are immediately hopped to.
（4）SoftReset states：Module repeatedly returns to ERROR, registration abnormity, and the events such as configuration update can lead to module
Jump to SoftReset states.Under the state, module is removed error and is counted, and initing is jumped to after executing soft reboot operation
State.
（5）HardReset states：When fatal error or soft reboot cannot solve the problems, such as, module can jump to HardReset
State.Under the state, module is removed error and is counted, and hard reboot operation is executed（To module power down and power on）After jump to
Initing states.
