Detailed Description
In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that the terms "first, second, etc. in the description of the present invention are only used for convenience of description of the present invention and should not be construed as limiting the present invention.
In the present specification, a low-end mobile phone is taken as an example to describe a terminal device, wherein the low-end mobile phone is only a product with limited storage space of an electronic product itself, but it is obvious to a person skilled in the art that the low-end mobile phone can be extended to an electronic product structure capable of performing text input to record simple information, and thus the following description of the specific embodiment is only for the purpose of example and is not to be considered as a limitation to the protection scope of the present invention. Those skilled in the art can also adapt the structure in accordance with the electronic product to be used when implementing the present invention.
The SIM card is an abbreviation of Subscriber Identity Module card. A general SIM card includes: a microprocessor; an eeprom (electrically Erasable Programmable Read Only memory) located in the SIM card, the eeprom being used to store all application files in the SIM card; ROM (Read-only Memory), Read-only Memory; ram (random Access memory), random Access memory; and an interface between the SIM card and the mobile phone, wherein an STK (abbreviation of SIM Toolkit, i.e. application tool on the SIM card) program stored in the SIM card drives the mobile phone to display an STK menu for user operation, thereby completing functions such as short message copying/transferring, short message searching, short message sending, etc.
The current smallest SIM card, with a memory capacity of 8KB, can typically store 100 sets of phone numbers and corresponding name text, as well as 15 sets of short messages. The current popular high-capacity SIM card can reach the storage capacity of 64KB, correspondingly, the SIM card can store 200 groups of phone numbers and corresponding name characters, and can also store 100 groups of short messages. The above memory capacity is clearly a valuable data storage resource for low end handsets.
Therefore, an embodiment of the present invention provides a note storage method for a low-end mobile phone by using a SIM card, where the SIM card has a memory, and referring to fig. 1 to 3, the method includes:
A. inputting note information, wherein the note information can be input through a note book function module in the mobile phone, and certainly, a friendly human-computer interface for creating and editing the note paper can be provided for a user on the mobile phone, and the user inputs brief information to be recorded in a text form;
B. splitting the event record information into i pieces of segmented information, namely SM1 and SM2 … … SMi; adding an information association packet header for recording the relation of each piece of information in the event record information into each piece of segmentation information (namely SM1, SM2, … …, SMi) to form each segment, namely SG1, SG2, … …, SGi; and storing the segments (SG 1, SG2, SG … …, SG) in a SIM card memory in the form of short messages. Certainly, the above-mentioned splitting of the memo information into i pieces of segmented information to form i pieces of information to be stored in the SIM card memory in the form of short messages may be accomplished automatically by selecting a "save" button to trigger the mobile phone after the user has input memo information, or may be accomplished by selecting a "save" button to trigger the mobile phone to output whether memo information is stored in the man-machine interaction interface (as shown in fig. 2) in the SIM card after the user has input memo information, and the user manually selects to store in the SIM card.
Specifically, as shown in fig. 1, fig. 1 is a schematic diagram of a frame structure for storing the segmentation information in a short message format according to the method in this embodiment. The information association header comprises a note identification bit ID1 and a segment identification bit ID 2. The note identification position ID1 is used for recording the mapping relationship between the short message and the note information, and the segment identification position ID2 is used for recording the note short message as the split segment of the note information.
The note identification bit ID1 occupies 8 bits, and the range of value can be 0 to 255. The segment identifier ID2 takes 8 bits and can range from 0 to 255.
Furthermore, because the memory of the SIM card can also store short messages received by the user from other terminals or sent to other terminals, in order to distinguish the short messages and the memo information from the short messages stored in the memory of the SIM card in the form of short messages, the information-related packet header can further include a FLAG bit FLAG, which is used to indicate that the short message corresponding to the information-related packet header is a part of the memo information, and the short message not received by the user from other terminals or sent to other terminals is beneficial to finding the split short message from the SIM card more quickly when the memo information is subsequently read. The FLAG bit FLAG occupies 8 bits, and may be 0 or 255.
And loading the information association packet header to the head end or the tail end of the segmented information. In this embodiment, the information association packet is loaded to the front end, i.e., the head end, of the segmented information, so that when the mobile phone system reads the memo information, the read short message is corresponding to which segment of which memo information according to the bits occupied by the flag bit and various identification bits in the preset information association packet, which is favorable for well forming complete memo information by each part of the subsequent dispersed memo information.
The event recording information can be split according to the size of the segmentation information not exceeding 136 bytes. Of course, the size of the segmented information can also be set through a human-computer interaction interface, or the mobile phone system can be set to other numerical values. Because the characters that each short message in the SIM card can store are limited. At present, the popular content of a short message can contain 140 bytes at most, and because the head of the associated information packet also needs to occupy a certain number of bytes, the event record information can be split according to the size of the segmented information not more than 136 bytes, so that the storage space of each short message can be utilized to the maximum extent,
please refer to fig. 3 to explain how to split the memo information according to the embodiment of the present invention.
Wherein,
STOP 1: and a user selects to store the event record information into the SIM card memory through a human-computer interaction interface, and the segment identification bit of the associated information packet header is initialized to i, wherein i is an integer. In this embodiment, i takes the value 0;
STOP 2: judging whether the byte number of the current event record information is less than 136, if not, executing a step STOP 3; if so, step STOP6 is executed;
STOP 3: intercepting the first 136 bytes of the current event-recording information to form ith segmentation information, simultaneously recording the byte number obtained by subtracting 136 from the byte number of the current event-recording information as the byte number of the current event-recording information, and automatically adding 1 to i to be used as a new value of i;
STOP 4: loading an information association packet header on the segmentation information to form an ith segment;
STOP 5: storing the ith segment into an SIM card memory in a form of short message, and recording a storage position Li in the SIM card memory; at this time, the step STOP2 is repeated, the next cycle is started, whether the byte occupied by the updated current memo information is larger than 136 is judged again, and if yes, the execution of STOP3 to STOP5 is started.
STOP 6: and forming segmentation information by using the current memo information, loading an information association packet header on the segmentation information to form an ith segment, and storing the ith segment into a SIM card memory in a short message form.
Because the situation that the number of bytes occupied by the current memo information is less than 136 only occurs under the situation that only 1 piece of segmentation information or the last piece of segmentation information exists, the memo information is already split and stored when the memo information at the moment is stored in the SIM card in a short message form.
Obviously, in step STOP5, the segments may be stored in the SIM card memory sequentially or sporadically in the form of short messages.
The steps STOP5 and STOP6 further include storing the storage location Li of each segment in a file in a form of one record in a forward manner, and establishing a mapping relationship between the file and the memo information. The file is saved in a specific location in the handset system.
The method can be implemented on the premise that the memory in the SIM card has enough space, so that the method can comprise the step of detecting the size of the idle capacity of the memory of the SIM card before the step of setting whether the input memo information is stored in the SIM card. When the remaining available storage space of the SIM is smaller than a certain value, the mobile phone system can not output the human-computer interaction interface prompting that the user can select to store the information in the storage space of the SIM card, or defaults that the memo information input by the user is not stored in the storage space of the SIM card under the condition, or outputs the human-computer interaction interface information such as insufficient storage space of the SIM card and the like to prompt the user.
Referring to fig. 4, fig. 4 is a human-computer interaction interface provided by a mobile phone system when a user wants to look up input memo information, wherein four pieces of memo information which can be looked up are displayed in the human-computer interaction interface, when the user chooses to look up a certain memo information, the short messages corresponding to memo identification bits corresponding to the selected memo information can be extracted through a mapping relation, the corresponding short messages are sequentially extracted according to the segmentation identification bits from small to large, and the extracted short messages are combined into memo information of a text for display after removing a packet header of associated information loaded on a front segment of the short message.
Fig. 5 is a schematic flow chart of data reading by the mobile phone system after the user selects to look up a certain memo information when storing each segment in the SIM card memory in sequence.
The first step is as follows: acquiring a file recorded with information of storage positions of all segments at a specific position of a mobile phone system, and acquiring all storage positions Li from the file;
the second step is that: sequentially obtaining segments positioned at each storage position Li;
the third step: removing the associated information packet head before each segment to extract each segment information;
the fourth step: sequentially synthesizing all the segmented information into event-recording information to be displayed;
the step of reproducing the split memo information is completed.
It is obvious from the above description that the note storage method using the SIM card for the low-end mobile phone provided by the present invention is adopted, after the user inputs the note information, because the note information is split into a plurality of segmented information, the associated information packet header is added to the segmented information, and then the split note information is stored in the memory of the SIM card in a short message manner, on the premise of not increasing the cost of the low-end mobile phone, the storage space of the SIM card is effectively utilized to provide the note information storage function for the user, and the convenience and the practicability of the use of the low-end mobile phone are provided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
