[0027] Next, specific embodiments will be used to describe in detail the technical solutions of this application and how the technical solutions of this application solve the above technical problems. The specific embodiments described below can be combined with each other to form new embodiments. For the same or similar ideas or processes described in one embodiment, they may not be repeated in some other embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0028] Figure 1 An embodiment of a method for storing and reading a phone book according to this application is shown.

[0029] Figure 1 The method for storing and reading a phone book shown includes: Step S101, partitioning the flash memory of the serial interface according to a predetermined rule to obtain storage partitions, and numbering the storage partitions;

[0030] Step S102, saving the start address and end address corresponding to each storage partition as a permanent storage key;

[0031] Step S103, within the storage partition, store the current contact-related information and the current call record-related information according to the size of the storage partition number, and save the current contact quantity information and the current call record quantity information within the storage partition as a permanent storage key;

[0032] Step S104, after completing the storage of the current information, turn off the storage function of the storage partition that has stored the current contact-related information and the current call record-related information;

[0033] Step S105, information is read in the flash memory by using the start address, end address, current contact number information, and current call record number information. In this specific implementation, by storing phone information in partitions in the flash memory and reading information in partitions, the repeated reading and writing of the same storage area can be reduced, extending the service life of the flash memory. At the same time, the phone information obtained in this application can be non-lost when the power is off. Compared with the prior art, the efficiency of the user to obtain phone information using this application is higher, and the obtained data is more stable.

[0034] In Figure 1 the embodiment shown, the method for storing and reading the phone book includes step S101, partitioning the flash memory of the serial interface according to a predetermined rule to obtain storage partitions, and numbering the storage partitions.

[0035] Specifically, taking QCC3007 Bluetooth as an example, the size of its flash (flash memory) is 4M. Therefore, the size of the partition related to the phone book set therein and its corresponding number can be as Figure 3 shown.

[0036] When information needs to be stored in the above partitions, taking the main phone book as an example, the original data of the main phone book can be stored in partitions 10 - 14 of the flash, and the sorted main phone book information can be stored in partitions 15 - 19. At the same time, when storing information, the start address and end address corresponding to the partition, as well as relevant information such as the number of phone entries and phone information, need to be saved as permanent storage key codes, so as to directly obtain the starting partition position and the required offset through the stored permanent storage key codes when reading information, and then quickly and efficiently obtain phone information in the specified partition.

[0037] In Figure 1 the embodiment shown, the method for storing and reading the phone book includes step S102, saving the start address and end address corresponding to each storage partition as permanent storage key codes. In this specific embodiment, the number of information reading times during information reading can be effectively reduced, and at the same time, the number of read and write operations on the flash memory can be reduced, which can improve the efficiency of information reading and the service life of the flash memory.

[0038] Specifically, obtain the start address and end address corresponding to each partition, and save the start address and end address corresponding to each partition as non-lost permanent storage key codes for subsequent obtaining of relevant information of the partition.

[0039] In Figure 1In the illustrated embodiment, the method for storing and reading a phone book includes step S103. In a storage partition, according to the size of the storage partition number, store the current contact related information and the current call record related information, and save the current contact number information and the current call record number information in the storage partition as permanent storage key codes.

[0040] Specifically, when the Bluetooth obtains the current phone information, traverse all the storage partitions, and in the storage partition with the smallest numbered number and the storage function not closed, store the current contact related information and the current call record related information, and use the current contact number information and the current call record number information in the current storage area as the permanent storage key code, and the storage area information related to the current contact number information and the current call record number information as the permanent storage key code for saving, and save the corresponding relationship between the storage space number and the phone information for subsequent information reading.

[0041] In a specific embodiment of the present application, in a storage partition, according to the size of the storage partition number, store the current contact related information and the current call record related information, and save the current contact number information and the current call record number information in the storage partition as permanent storage key codes, including: before storing the current contact related information and the current call record related information into the storage partition, first erase the storage information in the storage partition.

[0042] Specifically, when storing the current contact information, a piece of current contact information includes its corresponding serial number information, number, name, phone path and other information. Therefore, usually the size of a piece of current contact information is 64. And the number of mobile phone address books is usually about 100 to 500. Taking a partition size of 20K and the number of mobile phone address books being 1000 as an example, each partition can store up to 320 pieces of current contact information at most. Considering the situation that the partition storage space is full, preferably, set the maximum number of phones in a partition to 312. The excess number of phones starts to be written in the next partition. When writing to a new partition, the method of erasing first and then writing can effectively avoid the existing data in the storage space, and thus avoid data overflow caused by writing information therein, and the space waste caused by writing data in the new storage partition. When storing the current call record related information, to ensure that as much information as possible is stored in the effective storage space and avoid waste of storage space by invalid information, first erase the information in the storage partition where the information needs to be stored, and then write the information.

[0043] In a specific embodiment of the present application, the original data of the current contact-related information and the current call record-related information is obtained, and the current contact-related information and the current call record-related information are sorted according to a predetermined classification rule. Then, according to the sorting result and the number of the storage partition, the current contact-related information and the current call record-related information are stored in the storage area, and the start address and the end address corresponding to each classification are saved as the permanent storage key codes.

[0044] Specifically, when the user needs to obtain the sorted information of the current contacts, first, all the original data storing the current contacts is obtained. According to the sorting rule, the original data of the current contacts is traversed, sorted, and the sorted result is stored in a new storage space according to the sorting result. Also, the start address and the end address of each classification storage location, and the current contact-related information corresponding to each classification are saved as the permanent storage key codes. Among them, the new storage space is the storage space of the classified storage space where the storage function is not closed.

[0045] Particularly, the present application does not limit the classification criteria, nor the specific location of the corresponding new storage space, and the user can make appropriate adjustments according to the needs.

[0046] For example, when the classification criterion is sorting by the first letter, the original data of the current contacts is traversed. According to the position of the original data in the storage partition, starting from the storage position of the first current contact as the starting position, offset by 64 each time, the first letter of each current contact is judged one by one, and the phone information is stored in a new storage partition in the order of letters A to Z. For example, it is stored in partitions 15 to 19. When the user needs to obtain the relevant information of the current contacts in order, the sorted current contact information is obtained from partitions 15 to 19. Among them, the sorting of the present application has no average wear.

[0047] In a specific embodiment of the present application, storing the current contact-related information and the current call record-related information includes: when storing the current call record-related information, reading the current call record-related information in each storage partition, and re-downloading the current call record-related information according to the storage partition; when the number of the current call record-related information reaches a predetermined threshold, re-reading the current call record-related information in each storage partition, and saving a predetermined number of the current call record-related information to the storage partition where the current call record-related information has not been stored. In this step, when reading the call records stored in the flash memory, by performing defragmentation, it not only ensures sufficient storage space for the next data storage, but also can store a predetermined number of call records to facilitate the user to search for call information.

[0048] For example, the default number of downloaded current call record information for each storage partition is 0. If 5 storage partitions are defined for storing call record information and the size of each partition is 2K, a partition can store at most 32 current call record information. To prevent information overflow, preferably, it is set that a partition can store at most 20 current call record information, and the excess number of records is written starting from the next partition. When there is no storage partition with the storage function turned off among the defined storage partitions, the current call record information is continuously written at the end position of the write position of the previous call record. When information is read after writing, the storage partition from which the information is read will turn off the storage function of this storage partition. At this time, when writing information again, the next storage partition of this storage partition needs to be opened, and the call record information is written in the next storage partition. When writing reaches the penultimate storage partition of the defined storage partitions for storing current call record information, after writing this penultimate storage partition, read the call information of all storage partitions for storing current call record information and perform fragmentation of the call information. Among them, when storing the current call record information, when information is not read immediately after writing the current call record information in the storage partition, the storage function of this partition is not turned off; when storing the current call record information, when information is read immediately after writing the current call record information in the storage partition, the storage function of this partition is turned off.

[0049] When fragmentation is not performed, reading call records starts offset from the beginning of the corresponding starting partition. That is, when reading call records, when the starting offset address of the starting partition remains unchanged, the starting point for reading information is fixed. After fragmentation, the partition positions of the starting offset address and the ending offset address of the starting partition change, so the starting point for reading information also changes accordingly.

[0050] The process of fragmentation is as follows: When storing information related to the current call record, read the information related to the current call record in each storage partition for storing call records and re-download the information related to the current call record in each partition; when the number of information related to the current call record reaches a predetermined threshold, re-read the information related to the current call record in each storage partition and save a predetermined number of information related to the current call record to the storage partition that has not stored the information related to the current call record. Among them, the predetermined threshold can take a value of 32 or 24, and the predetermined number can take a value of 20.

[0051] In a specific embodiment of the present application, when storing the next phone book information of the current phone book information, the next phone book information is stored in the next storage area after the last storage area where the current phone book information is stored.

[0052] Specifically, after writing the phone book information received for the current number of times, regardless of whether the storage space corresponding to the current phone book information is fully occupied, the storage function of the corresponding storage space is closed. Therefore, when the writing requirement for the next phone book information is received, the next phone book information is stored in the next storage area after the last storage area where the current phone book information is stored.

[0053] In Figure 1 The embodiment shown, the method for storing and reading the phone book includes step S104 of closing the storage function of the storage partition that has stored the information related to the current contact and the information related to the current call record after storing the current information.

[0054] In a specific embodiment of the present application, after storing the current information, closing the storage function of the storage partition that has stored the information related to the current contact and the information related to the current call record includes: when storing the information related to the current call record in the storage partition, when reading the information related to the current call record, closing the storage function of the storage partition that has stored the information related to the current call record.

[0055] Specifically, after storing the current information, closing the storage function of the storage partition that has stored the information related to the current contact and the information related to the current call record, and when storing the information related to the current call record in the storage partition, when reading the information related to the current call record, closing the storage function of the storage partition that has stored the information related to the current call record can effectively ensure the reliability of the data and can also effectively prevent data loss of the obtained phone book information during storage.

[0056] In Figure 1 The embodiment shown, the method for storing and reading the phone book includes step S105 of reading information in the flash memory by using the start address, end address, current contact number information, and current call record number information.

[0057] Specifically, when reading the phone book from the flash memory, the start address of the reading position is the position of the start address that was previously saved as the permanent storage key code. Starting from this position, each time it is offset by 64 bits, a contact information can be read. If you want to obtain N consecutive phones starting from a certain position M as the starting offset position, start reading from position M, offset by 64 each time, and after offsetting N times, the required phone information can be obtained.
