Method and device for code conversion of short messages

Abstract

The invention discloses a method and a device for the code conversion of short messages. The method comprises: a code conversion driving table is stored in a short message center, and the corresponding relation of the code values of characters in an American standard code for information interchange (ASCII) code table and the code values of the same characters in a global system for mobile communications (GSM) code table is recorded in the code conversion driving table; and after the short message center receives the short message, when a sender and a receiver adopt different short message encoding types, the code value of the received short message is found out from the code conversion driving table according to the short message encoding type which is adopted by the sender, so that the code value, which corresponds to the code value of the short message, of the short message encoding type which is adopted by the receiver is obtained. The code conversion driving table is added in the short message center, custom code table conversion can be realized through the code conversion driving table no matter which country regions the short message center is used, and a new code table conversion function does not need to be temporarily developed.

Description

technical field [0001] The invention relates to the technical field of short message transmission, in particular to a method and device for code conversion of short messages. Background technique [0002] The code table conversion of short message content is a core technology of the short message center. The short message center supports various short message transmission protocols, for example, GSM0340 (Global System for Mobile Communications 0304) protocol and SMPP (Short Message Point-to-Point) protocol. GSM0304 is used for communication between GSM terminals. The SMPP protocol is used for communication between external short message entities, and different protocols use different short message code tables. [0003] GSM0340 uses the GSM code table (see GSM0338 protocol for details), such as figure 1 Shown is the GSM basic code table, such as figure 2 Shown is the GSM extended code table; the SMPP protocol uses the ASCII (American Standard Code for Information Interch...

AI Technical Summary

Problems solved by technology

In practice, after the short message center converts the code table of the short message, the content of the converted short message does not completely match the content of the original short message, which leads to the transmission of the wrong short message content to the receiving end, reducing the Quality of service to users
