Abstract

The invention discloses a method for quickening the power-on speed of a mobile phone, comprising the following steps of: S1. powering on the mobile phone, and reading basic data on an SIM (Subscriber Identity Module) card; S2. judging whether the random storage memory in the mobile phone has cache data, if yes, performing S3, and otherwise performing S4; S3. judging whether the cache data in the random storage memory is same with the basic data on the SIM card, if yes, performing S5, and otherwise, performing S4; S4. storing the basic data on the SIM card in the random storage memory; and S5. when the basic data is required, directly taking the basic data from the random storage memory. The method can shorten the power-on time of the mobile phone.

Example Embodiment

[0013] See figure 1 , figure 1 Shown is a schematic diagram of the first embodiment of the method for accelerating the startup of a mobile phone according to the present invention. The present invention provides a method for accelerating the startup of a mobile phone. The method includes the following steps:
[0014] Step S1: Turn on the mobile phone and read the basic data on the SIM card. The basic data is used to store various application data and management information. According to the storage structure, the basic data can be divided into transparent files, linear fixed files, and circular files. file. Transparent file refers to: it is composed of a string of bytes. When reading or modifying, an offset is used to point out the starting position of the string to be manipulated, and the number of bytes to be read or modified is given. The first of the file is relative The address is 0, and the number of records contained in the file is in the header information. Linear fixed file refers to: it is composed of a series of fixed-length records, the record number of the first record is 1, the total length of the file is equal to the product of the record length and the number of records, and the number of records is included in the header information. Cyclic file means: store records in the tenth day of the time. If all records are occupied, the oldest one will be overwritten in the next storage. Consists of a fixed length and a fixed number of records, connecting the last record with the first. When the pointer points to the last record, the next record is the first record. When the pointer points to the first record, the previous record is the last one, and the most recently updated record is the first record, which was updated earliest The last one.
[0015] Step S2: Determine whether there is cache data in the random storage memory of the mobile phone, if yes, go to step S3, otherwise go to step S4;
[0016] Step S3: Determine whether the cache data in the random storage memory is the same as the basic data on the SIM card, if yes, go to step S5, otherwise go to step S4;
[0017] Step S4: Store the basic data on the SIM card in the random storage memory;
[0018] Step S5: When the basic data is needed during the startup of the mobile phone, the cache data is directly obtained from the random storage memory without reading the basic data from the SIM card.
[0019] It can be understood that after the step S4, it further includes: when the basic data is needed, the cache data is directly obtained from the random storage memory, without the need to read the basic data from the SIM card.
[0020] And the basic data is, for example, the International Mobile Subscriber Identity (IMSI), which is a number assigned to uniquely identify a mobile user internationally.
[0021] See figure 2 , figure 2 Shown is a schematic diagram of the second embodiment of the method for accelerating the startup of a mobile phone according to the present invention. The present invention also provides another method for accelerating the startup of a mobile phone, the method includes the following steps:
[0022] Step S11: Turn on the mobile phone and read the specific basic information on the SIM card;
[0023] Step S12: Determine whether there is specific cache data in the random storage memory of the mobile phone, if yes, go to step S13, otherwise go to step S14;
[0024] Step S13: Determine whether the specific cache data in the random storage memory is the same as the specific basic data on the SIM card, if yes, go to step S15, otherwise go to step S14;
[0025] Step S14: Store the specific basic data on the SIM card in the random storage memory;
[0026] Step S15: When the specific basic data is needed during the startup of the mobile phone, the specific cache data is directly obtained from the random storage memory without reading the specific basic data from the SIM card.
[0027] It can be understood that, after step S14, it further includes: when the specific basic data is needed, the specific cache data is directly obtained from the random storage memory without reading the specific basic data from the SIM card.
[0028] Among them, the specific basic data is, for example, basic data that requires permission when updating, because in the SIM card used by general users, some basic data fields are necessary for booting but have permission to change, and users or ordinary devices cannot easily Modification, so if the SIM card is not replaced, this kind of basic data is stored in the mobile phone. When the device is turned on, it is not necessary to access the SIM card, which can speed up the boot process. The basic data with updated ADM attributes is very unlikely to change in general use. The specific basic information is, for example, the 3GPP TS 31.102 (USIM, Universal Subscriber Identity Module, Universal Subscriber Identity Module) specification and the information mentioned in the 51.011 (SIM) specification that all update conditions belong to the administrator (ADM) authority. Specifically, the specific basic data is, for example, an International Mobile Subscriber Identity (IMSI), which is a number assigned to uniquely identify a mobile user internationally.
[0029] Compared with the prior art, the method for accelerating the startup of a mobile phone of the present invention stores the basic data (Element File, EF) in the SIM card in the internal memory of the mobile phone, so that each time the mobile phone is turned on, the internal memory is directly accessed. Yes, there is no need to read the aforementioned data from the SIM card, which saves the phone boot time and speeds up the phone boot process.
