Method and system for realizing CLASS 0 short message transmission

Abstract

The invention discloses a method and a system for realizing CLASS 0 short message transmission. The method comprises the processes of transmitting CLASS 0 short messages in a C (IS95, 1X, EVD0) network and between the C network and a WG (WCDMA / GSM) network, wherein a priority field in a priority indicator adopted by a short message coding mode in the C network is expanded to increase identifiers defining CLASS 0 short messages; the processes of transmitting the CLASS 0 short messages in the C network and in the WG network are substantially the same; and in the process of transmitting the CLASS 0 short messages between the C network and the WG network, when the CLASS short message is received from an external network, a short message center in the C / WG network needs to convert a priority value of the short message into that corresponding to the C / WG network in which a terminal can identify that the short message is the CLASS 0 short message and directly display the CLASS 0 short message. Through the method and the system, the CLASS 0 short messages can be transmitted among the terminals in the C network and the terminals in the C network and the WG network so as to realize the win-win situation of the WG network and the C network.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a method and system for realizing transmission of CLASS 0 short messages in WG (WCDMA / GSM) network and C (IS95, 1X, EVDO) network. Background technique [0002] At present, the global mobile communication network mainly includes WG network (WCDAM / GSM), C network (IS95, 1X, EVDO), and TG network (TD-SCDMA / GSM). SMS function is a very important function of mobile communication network. A fast, convenient and economical communication method has won the favor of the majority of users. However, since there are more and more spam text messages, the user cannot check the received text messages immediately because of busy work or inconvenience, so it is likely to delay checking important text messages. To this end, the operator provides CLASS 0 SMS service. CLASS 0 text messages are high-level text messages, also commonly known as emergency text messages....

AI Technical Summary

Problems solved by technology

With CLASS 0 text messages, receiving users can directly view the relevant content of important text messages on the display screen. These advantages have won the favor of a large number of users; however, currently CLASS 0 text messages can only be transmitted on the WG network, not on the C network. Furthermore, it cannot be transmitted between the WG network and the C network, which has brought inconvenience to many users
