Description

Terminal information processing method and device

Technical field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for processing terminal information.

Background technique

With the development of technology, the current data processing methods are various, such as mobile phone short messages, mobile phones and other mobile terminals generally use PDU (Protocol Data Unit) data string, SMS (Short Message Service) In the short message service specification, three types of encoding can be used in the PDU Mode to encode the transmitted content. They are 7-bit, 8-bit, and USC2 encoded. 7-bit encoding is used to send ordinary ASCII characters. It converts 8-bit ASCII encoding (American Standard Code for Information Interchange) (highest bit is 0) into 7-bit encoding, ie every 8 characters can be compressed. Into seven. Bit8 of the ASCII 8-bit code is removed, and the next few bits of the next 7-bit code are sequentially moved to the front to form a new 8-bit code. UCS2 encoding is used to send Unicode characters. The maximum size of the user information segment of the PDU string is 140 bytes, so the maximum number of short messages that can be sent in the three coding modes is 160, 140, and 70, respectively.

If the content of the short message is English symbol or number, the 7-bit encoding method is adopted, so that the length of each short message can be up to 160 characters, and for the short message containing Chinese characters, only USC2 encoding can be used, and the length of one short message is reduced to 70 characters. If the content of the short message is greater than 70 characters, it can only be split into multiple transmissions. This method increases the number of short messages sent, and correspondingly increases the communication cost, which also imposes a burden on the service provider.

It can be seen that the processing method of the data in the prior art is relatively simple, and the processing method of the data is not flexible.

In view of the problem of relatively single information coding methods in the related art, no effective solution has been proposed yet.

In order to make the technical solutions and implementation methods of the present invention clearer, the implementation process will be described in detail below in conjunction with the preferred embodiments of the present invention.

The preferred embodiment of the present invention provides an improved character adaptive coding method. The invention of the preferred embodiment of the present invention is that when a user edits a short message, the terminal automatically determines the content of the short message to adopt the most economical coding scheme. If the content of the short message is all ASCII characters, the default 7-bit encoding is adopted; if the short message containing the Chinese characters and characters in the short message content is preprocessed, UCS2 encoding and ASCII encoding are respectively performed, and finally combined and then subjected to 7-bit compression encoding. The number of encoded bytes formed by the hybrid encoding is compared with the number of UCS2 encoded bytes used by the default terminal, and the terminal automatically selects the least number of bytes as the preferred encoding.

In a preferred embodiment of the invention, the preferred encoding is determined based on the content of the short message, and if all are ASCII characters, 7-bit encoding is employed. If there are Chinese characters and characters, there are two kinds of encoding possibilities: one of them requires a combination of UCS2 encoding and 7-bit encoding to form a mixed encoding. Chinese characters are pre-processed for UCS2 encoding, followed by 7-bit encoding along with other ASCII characters. In addition, the USC2 encoding is adopted by default.

In the hybrid coding scheme of the preferred embodiment of the present invention, special symbols need to be added to the beginning and end of the conversion character, and continuous Chinese only needs to be added once. In the preferred embodiment of the present invention, the terminal adds a special character "#" before and after the character is converted to obtain the short message content "#converted character #" to be transmitted.

Optionally, the preferred coding scheme is not only used for the short message module in the mobile, but also applicable to Other modules in the terminal that use character encoding schemes, such as MMS. String encoding is widely used in terminal communication.

It should be noted that, in the receiver terminal decoding scheme, the transmitting terminal sets the user information encoding mode (TP-DCS) in the PDU string for sending the short message, and if it is the UCS2 encoding, sets the 08 to the UCS2 encoding, and if it is the 7Bit encoding. Set to 00 for 7Bit encoding, and if mixed encoding, set 00 to 7Bit encoding. The receiver terminal decoding adopts a corresponding decoding scheme according to the user information encoding mode (TP-DCS) in the received PDU string, and 08 represents the UCS2 decoding mode. 00 is 7Bit coded. Different from the prior art, if it is determined that 7Bit is decoded, there may be secondary decoding. Secondary decoding requires traversing the entire string. When a special symbol is encountered, UCS2 is decoded for the following characters, and a Chinese character is obtained every 2 bytes until the next special symbol.

The preferred embodiment of the present invention further provides an information encoding and decoding apparatus, wherein the encoding apparatus comprises: an editing module configured to receive original characters input by a user; an encoding module configured to perform PDU encoding according to original characters; a comparison module, setting In order to calculate and compare the length of the encoded bytes after preprocessing of different schemes, the optimal coding scheme is finally determined. The decoding device comprises: a display module, configured to output the user original character obtained by the interface; the decoding module is configured to perform PDU decoding according to the original character; and the determining module is configured to determine whether there is a special character after the first decoding and start secondary decoding. .

Optionally, the editing module is visible to the user and belongs to a part of the terminal UI interaction, and the characters input by the user are passed to the encoding module for processing.

Optionally, the encoding module uses four encoding methods to encode the transmitted content, which are 7-bit, 8-bit, USC2 encoding, and hybrid encoding.

ASCII is a coding specification used to represent English characters. Each ASCII character occupies 1 byte (8 bits). The 7-bit encoding converts 8-bit ASCII encoding (the highest bit is 0) into 7-bit encoding, that is, every 8 characters can be compressed into seven. Bit8 of the ASCII 8-bit code is removed, and the next few bits of the next 7-bit code are sequentially moved to the front to form a new 8-bit code.

UCS2 encoding is used for Unicode characters and is encoded with 2 bytes. Convert unicode encoding to UCS2 encoding. First of all, we know that UCS2 encoding converts a single character into a 16-bit wide character, that is, the unicode of this character is converted to hexadecimal, the upper two bits are complemented by 0, and the length of the string is 2-digit hexadecimal number, PDU mode. The length of the string is twice that of the original message. UCS2 encoding converts each character (1-2 bytes) into 16-bit Unicode according to ISO/IEC10646. Wide character. You can simply call the API function or look up the table to achieve encoding and decoding.

8-bit encoding is usually used to send data messages, used to send and receive data messages, such as pictures or ring tones, ordinary text messages will not be used.

Hybrid coding, if the content of the message contains Chinese character words, the pre-processing is performed, that is, the Chinese characters in the content are first converted into characters, and the single characters are converted into 16-bit wide characters, that is, the unicode of the character is converted into hexadecimal. And use the flag bit to distinguish it from other characters, and then send all characters (characters with Chinese character conversion) according to ASCII encoding and then send them using 7-bit compression encoding.

Optionally, the comparison module is configured to compare the final byte lengths of different coding schemes, and if all are ASCII characters, the default 7-bit encoding is used, and the 7-bit encoded byte length is calculated; for the short message, the Chinese characters are also included. After pre-processing with the character's short message, UCS2 encoding and ASCII encoding are performed separately, and finally 7-bit compression encoding is performed. The number of encoded bytes formed is compared with the number of UCS2 encoded bytes used by the default terminal, and the final terminal automatically selects Excellent coding scheme.

Optionally, the receiving terminal decoding device is similar to the encoding device, and the receiving terminal performs decoding according to the setting of the user information encoding mode (TP-DCS) in the PDU string of the received short message, and if the UCS2 is decoded, the UCS2 decoding is started, if the 7Bit encoding is performed. Then, 7Bit decoding is started. After 7Bit decoding, it is necessary to determine whether there is a special character to determine whether secondary decoding is required, and if secondary decoding is required, UCS2 decoding for the converted character is started. That is, the characters converted by Chinese characters are decoded according to UCS2. Secondary decoding requires traversing the entire string. When a special symbol is encountered, UCS2 is decoded for the following characters, and a Chinese character is obtained every 2 bytes until the next special symbol.

FIG. 6 is a schematic diagram of encoding and decoding information of a mobile terminal according to a preferred embodiment of the present invention, which is applied in a short message scenario. As shown in FIG. 6, A is a calling party mobile phone, and B is a called party mobile phone.

The user edits a short message. If the content of the short message does not contain Chinese characters, no pre-processing is performed. The characters in the content are ASCII-encoded and then sent using 7-bit compression encoding. If the content of the short message contains Chinese characters, the pre-processing is performed first, that is, the Chinese characters in the content are first converted into characters, and the flag is distinguished from other characters, and then all characters (characters including Chinese characters converted) are used in accordance with ASCII encoding. Bit compression coding. The final number of encoded bytes is compared with the number of UCS2 encoded bytes used by the default terminal. The final terminal automatically selects the optimal coding scheme, assuming a hybrid coding scheme is employed.

After receiving the data packet, the receiver processes according to the inverse process of the sender code. If it is judged that the encoded data contains special characters, the first decoding is performed first, that is, 7-bit decoding, and hexadecimal ASCII characters are obtained, and then the hexadecimal ASCII characters are decoded second, and respectively obtained by UCS2 decoding. Chinese characters, using the ASCII comparison table to get the characters, that is, the original text messages sent by the sender. If it is judged that the encoded data does not contain special characters, it is processed according to the default decoding method.

FIG. 7 is a flowchart of a method for encoding and decoding information of a mobile terminal according to a preferred embodiment of the present invention, which is applied in a short message scenario.

The inventive idea of the method is that the implementation architecture includes a user terminal, a communication network, and a short message center. The user terminals include fixed phones, mobile phones, and other devices that can implement network interaction. Communication networks include mobile telephone networks, fixed networks, and the Internet. The user terminal system specifies a special symbol as # in order to distinguish between the original character and the Chinese character conversion character. As shown in FIG. 7, the method steps include:

Step S702: A new short message is input, and the short message content is input, and the content is assumed to be: “text message test123”.

Step S704: The system determines whether the content contains Chinese characters. If yes, step S706 is performed. If the Chinese characters are not included, then step S708 is performed.

Step S706: Pre-processing the Chinese characters in the short message content, specifically, traversing the short message content, if the Chinese character is encountered, the UCS2 encoding is performed, and each Chinese character is converted into a 2-byte character. In this example, the Chinese characters "short" and "letter" are converted into "77ED" and "4FE1" according to the UCS2 code, and the original short message content "text test123" is converted into the string "4FE177EDtest123" after the traversal. Add the special symbol # to the beginning and end of the conversion character, and the continuous Chinese character only needs to be added once. In this example, the system adds the special character "#" before and after the "4FE177ED" string to get the short message content "#4FE177ED#test123" to be sent.

Step S708: Perform 7-bit encoding on the short message content. In this example, the system encodes the string of “#4FE177ED#test123” into a string of “239AB118BBDD8AC411BD3CA7C76433” according to the 7-bit encoding mode.

Step S710: The comparison module compares the number of encoded bytes formed by the hybrid coding scheme with the number of encoded bytes that are UCS2 encoded by default, and the terminal automatically selects the minimum number of bytes scheme as the optimal coding scheme.

In this embodiment, the number of encoded bytes formed by the hybrid coding scheme is 15 bytes, which is adopted by default. The number of UCS2 encoded bytes is 18 bytes, and the final terminal automatically selects the hybrid coding optimal coding scheme, and sets the short message PDU string user information coding mode (TP-DCS) to 00 or 7Bit code.

Step S712: A encapsulates the string into a short message data packet and sends it to B, and B receives the data packet sent by A.

Step S714: B performs 7-bit decoding on "239AB118BBDD8AC411BD3CA7C76433" to obtain a decoded character string "#4FE177ED#test123", and judges that the special character # is included, and then performs the second decoding, that is, traversing the character string and the special symbol # For comparison, if the same, the traversal is stopped and step S716 is performed, if not the same until the traversal is finished and the process proceeds to step S718.

Step S716: traversing the entire character string, and encountering the special symbol #, UCS2 decoding is performed on the following characters, and a Chinese character is obtained every 2 bytes until the next special symbol. In this example, the character string "4FE177ED" between the special symbols "#" is decoded into UCS2 as "SMS", and the other characters remain unchanged.

Step S718: The last obtained character string is the short message content sent by A. In this example, the character string "text test123" obtained after two decodings is the actual short message content.

With the solution of the preferred embodiment of the present invention, for a short message containing Chinese characters, the number of sent short messages can be significantly reduced, thereby reducing the communication cost of the user, reducing the burden on the service provider, and improving the user experience.
