Description
Technical field
The invention belongs to technical field of mobile terminals, relate in particular to and restart system and method automatically after a kind of smart mobile phone Modem crashes.
Background technology
Continuous development along with society, the mobile of people's work and life constantly strengthened, so people are also increasing to the demand of portable terminal, people utilize portable terminal except carrying out voice and messaging communication, also need to enjoy from network Email, consult information, services such as film are downloaded and viewed and admired to picture.
The hardware configuration of smart mobile phone of the prior art as shown in Figure 1, the smart mobile phone hardware system mainly is made of intelligent operating system application processor 101 and 102 liang of big main bodys of Modem wireless communication module, both power supplys are powered by battery 100, and the Modem wireless communication module is realized the GSM standard of mobile phone or data communication and the function of voice communication of CDMA standard or mobile communication standards such as WCDMA standard or TD-SCDMA; Intelligent operating system application processor operation system software and operation are based on the application software of moving on this operating system, and realization is to the application management of Modem wireless communication module and other various function peripheral hardwares.Usually, can be operated in a kind of in following three kinds of patterns after the Modem start: 1, communication service pattern: Modem is in conversation or data service communications status; 2, idle application model: Modem is carrying out user's operational order, enters corresponding function application menu, but does not enter conversation or data service communications status; 3, sleep pattern: Modem does not carry out Any user instruction and operation, is in stand-by state, enters the low-power consumption battery saving mode.Can be operated in following two states after the intelligent operating system application processor start: 1, application model: the user carries out various application operatings at the interface that Activates Phone; 2, sleep pattern: application processor dormancy.
Though more than be that Modem or intelligent use processor all can make separately that module enters corresponding mode of operation according to the mobile phone realistic application conditions, when two intermodules need carry out data interaction, initiate to ask alternately and inform the other side's self working mode to the other side's module earlier by the mutual initiator in two modules, at this moment the side's of response module can be adjusted after the request of receiving and self enter duty and inform initiator's module self working state, after finishing shaking hands between this series module, two modules just can carry out data interaction.
In above-mentioned normal procedure intelligent operating handset mode, Modem wireless communication module and intelligent operating system application processor are all directly powered by battery, during mobile phone power-on, at first be the start of intelligent operating system application processor and operation intelligent operating system, make the Modem accessing mobile communication network and enter standby mode by intelligent operating system application processor control Modem start again after start is finished.Modem and intelligent operating system system applies processor are owing to the processor system that has separately, their operations separately have certain independence, just carry out handshake communication when having only the data interaction of needs, they can mutual report mode of operation separately give the other side when not needing data interaction.
But because intelligent mobile phone system complexity, Modem and intelligent operating system system applies processor also all are to be made of all kinds of CPU architecture processor kernels, the same with conventional computer, these CPU also have the possibility of deadlock, and its performance is that Modem crashes or the intelligent operating system application processor crashes.Modem can not answer, dial phone or carry out data communication when crashing, and the user just can not carry out any operation when the intelligent operating system application processor crashed; And some degree of depth to crash be to recover by common start again, need to make again system cut-off to reset as computer and just can restart.So we must start shooting by the plug battery again and just can reply sometimes after mobile phone crashes, its reason be mobile phone when crashing since battery also be connected with system, make each functional block of internal system keep metastable state because of the capacitance energy storage effect, cause system not reset, have only the electric charge of capacitance energy storage is consumed after battery pulled out by system's self discharge, system thoroughly could the assurance system normally be resetted, restart after the discharge.
So prior art exists not enough, need to be improved and enhanced.
