Embodiment Construction

[0037] The basic idea of ​​the present invention is to verify the memory data of the terminal in a manner based on the summation of memory data.

[0038] Specifically, divide the memory space of the terminal to be verified into one or more specific units, calculate the sum of all byte data in each specific unit, compare the obtained value with the correct value, and if they are consistent, determine the corresponding The memory data of the specific unit is correct, otherwise, it is judged that the memory data is wrong.

[0039] When dividing a unit, usually set the size of each specific unit to be equal, such as 1Mbyte.

[0040] When the terminal is in the working state, when verifying the written memory data, the sum of all byte data expected to be written in each specific unit is used as the correct value; after writing the memory data, calculate each sum of all bytes of data in a particular cell, and compare the resulting value with the correct value.

[0041] When verify...

Abstract

The invention discloses a method for verifying terminal and stored data, which comprises the following steps: the memory space of the terminal to be verified is divided into one or more discrete cells to respectively calculate the sum of all byte data therein, the stored data of the corresponding discrete cell is judged to be accurate or not according to the consistency of the comparison result between the obtained value and the accurate one. In the invention, the strategy for defining the memory space and the method for verifying the stored data are adopted, so that the completeness and the accuracy of the stored data are guaranteed, the abnormal condition of the entire terminal system caused by incomplete stored data during the operation or in a standby is avoided, and the problems such as memory leak and out-of-bound access are solved, thereby guaranteeing the normal and reliable operation of the terminal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a terminal and a method for verifying memory data. Background technique [0002] With the gradual development of domestic 3G network construction, the three major mobile communication operators have officially entered the 3G era. However, due to the initial stage of the construction of the current 3G network and the next period of development, the coverage level of the 3G network has been continuously optimized and improved for more than ten years compared with the 2G network. All natural villages) or the depth of coverage (such as indoors, basements and subways, etc.), there is a big gap, so major operators also coincidentally regard the long-term coexistence of 2G and 3G dual networks as their own operating goals and strategies. China Mobile even put forward the three-no principle of "no change of card, no change of number, and no registration" and the uniform TD (Time Divi...
