Method, system and service platform for realizing ussd service in cdma communication system

Abstract

The invention discloses a method and a system of achieving unstructured supplementary service data (USSD) service in a code division multiple access (CDMA) communication system and a service platform. The method includes the steps that a USSD start request message sent by a mobile terminal in a voice service in a dialing mode or a call transferring mode is obtained by the business platform through an intelligent network mode or a signal monitoring mode, wherein the USSD start request message comprises service codes and the service platform recognizes service classes needed to be triggered according to the service codes; the mobile terminal is responded as an intelligent mobile terminal, wherein a triggering message in a preset mode is sent to the mobile terminal by the service platform and the triggering message comprises service class information; a wireless application protocol (WAP) client-side in the mobile terminal is triggered by the triggering message to start, a WAP is started to be connected with WAP servers corresponding to the service classes, and USSD interactive session data service is interactively achieved with the WAP servers. The method and the system of achieving the USSD service in the CDMA communication system and the service platform have the advantages of enabling a CDMA mobile terminal to achieve USSD service through WAP functions.

Description

technical field [0001] The present invention relates to communication technology, especially a method, system and service platform for realizing unstructured supplementary data (Unstructured Supplementary Service Data, hereinafter referred to as USSD) service in a code division multiple access (Code Division Multiple Access, hereinafter referred to as: CDMA) communication system. Background technique [0002] With the development of telecommunication services and the popularization of 3G terminals of the 3rd Generation Telecommunications (hereinafter referred to as 3G) standard, data service applications are gradually favored by users. For operators, data services not only generate income, but also improve their business competitiveness. The competitiveness of data services determines the success or failure of operators to a certain extent. [0003] The USSD service is a real-time online new interactive session data service based on the Global System for Mobile Communication...

AI Technical Summary

Problems solved by technology

[0007] Currently, because the CDMA technical specification does not support USSD, CDMA users cannot use data services triggered by voice calls;

[0008] Since the WAP technology cannot provide the service trigger of the voice dialing mode of the mobile terminal, the WAP service cannot form a combined product with the voice service;

[0009] When the user enters the WAP service through the menu, he needs to enter the menu layer by layer, the operation is cumbersome, and the time required is relatively long, usually 4 to 5 minutes, which limits the development of the WAP service;

[0010] In particular, the single service trigger makes it impossible for WAP technology to be flexibly applied to voice services, such as: data selection on mobile phone screen for voice song request transfer to WAP web page, data service application for voice call transfer, etc.
