Embodiment Construction

[0049] As mentioned earlier, Unicode is a character encoding scheme designed by an international organization, and it is an encoding scheme that can accommodate all languages ​​and characters in the world. Currently Unicode has two encoding formats, UCS2 and UCS4, where UCS2 is encoded with two bytes, while UCS4 is encoded with 4 bytes. UCS stipulates how to use multi-byte encodings to represent various characters, and what format to transmit these encodings is stipulated by the UTF encoding specification. Common UTF encoding specifications include UTF-8, UTF-7, and UTF-16 , the most commonly used is UTF-8.

[0050] UTF-8 is encoded in sequences of 1 to 6 bytes (1 byte equals 8 bits). In a sequence that uses only one byte, the high-order bit of the byte is 0, and the other 7 bits are used to encode character values. In a sequence of n (n>1) bytes, the highest bit of the 8 bits of the initial byte is 1, the next bit is 0, and the remaining bits of the byte are bits containing...

Abstract

The invention includes steps: appointing adoption of UTF coding for carrying out transmission for input/output characters at input end and display end of short message; building mapping relation needed by conversion between character codes; based on built mapping relation to carry out conversion between UTF codes and 7 bit codes or UCS codes. The invention also discloses network devices of possessing function of sending and receiving short message. Holding and maintaining conversion relation for two kinds of codes, the invention can support languages for each country. Features are: small storage space needed, saving fabricating cost and cost for late maintenance.

Description

technical field [0001] The invention relates to mobile communication, network communication and character coding technology, in particular to a code conversion method for sending and receiving short messages and a network device applying the method. Background technique [0002] With the development of network technology and the continuous growth of user business needs, routing devices will access the WAN through GPRS (General Packet Radio Service) or 3G (3rd Generation Mobile Communications System) data cards. It has become a common application, and users can access the Internet (Internet) through this type of routing device. [0003] An important function of mobile communication is sending and receiving short messages. When the routing device is connected to the GPRS or 3G mobile communication network, it also has the function of sending and receiving short messages. After the user uses a web (World Wide Web) browser to connect to the routing device, the short message is...
