Further, the second implementation for restarting localization method the present invention is based on memory management is proposed based on first embodiment
Example.The second embodiment for restarting localization method managed based on memory and the first reality for restarting localization method managed based on memory
The difference for applying example is, includes according to the step of state value of Monitoring instruction reading key message point：
Step b reads the first state value of key message point preset quantity according to Monitoring instruction according to the first reading frequency.
Step c, if all being determined according to the first state value of preset quantity, direct memory access does not occur exception, according to the
Second state value of two reading frequencies reading key message point preset quantity.
Step d, if all being determined according to the second state value of preset quantity, direct memory access does not occur exception, according to the
The third state value of three reading frequencies reading key message point, wherein the second reading frequency is greater than the first reading frequency, less than the
Three reading frequencies.
Mobile terminal is in the process of state value for reading key message point according to Monitoring instruction：Mobile terminal is according to monitoring
The first state value of key message point preset quantity is read in instruction according to the first reading frequency, and judges read preset quantity
First state value whether can determine that direct memory access does not occur exception.If the first state value of read preset quantity
It can determine that direct memory access does not occur exception, then read the second of key message point preset quantity according to the second reading frequency
State value, and judge whether the second state value of read preset quantity can determine that direct memory access does not occur exception.
If the second state value of read preset quantity can determine that direct memory access does not occur exception, frequency is read according to third
Rate reads the third state value of key message point preset quantity, to determine key message point corresponding position according to third state value
Whether direct memory access there is exception.
Wherein, the second reading frequency is greater than the first reading frequency, and is less than third reading frequency.First reading frequency,
Two reading frequencies, third reading frequency and preset quantity are arranged according to specific needs, and such as the first reading frequency can be arranged
It is primary to be read at interval of 1 second, the second reading frequency is set as reading once at interval of 3 seconds, third reading frequency is arranged
Primary to read at interval of 5 seconds, preset quantity is set as 5.I.e. when mobile terminal according to Monitoring instruction continuous 5 times with 1 second between
After the state value of reading all shows that direct memory access exception does not occur, 5 key message points pair were continuously read at interval of 3 seconds
The state value answered, if 5 state values read at interval of 3 seconds all showed that direct memory access does not occur exception, at interval of 5 seconds
The corresponding state value of 5 key message points is continuously read, determines key according to 5 state values continuously read at interval of 5 seconds
Whether the direct memory access of information point corresponding position there is exception.
It should be noted that in other embodiments, the reading that the dotted state value of key message is read in setting can be further added by
