Problems solved by technology

In this way, whenever the MS needs a new USSD service, it needs to provide a new USSD request. Moreover, the user who needs the USSD service will memorize a large number of service codes. At the same time, the USSD center and the USSD service application cannot directly Direct service transfer or switching between two service applications, resulting in inflexible USSD service development

Embodiment Construction

[0022] In a mobile communication system, people usually hope that the system can provide a service application specially used for navigation. Through the USSD service menu, guide users to access the service application they need. When the selected service application no longer meets the needs, they can return to the above The first-level business menu selects other business applications again. A basic requirement to meet this requirement is that after USSDC establishes a session with a certain USSD service application, the service application can also transfer the session to other USSD service applications. Here it is the problem to be solved by the present invention.

[0023] figure 1 It is the interface model diagram of the TDMA digital cellular mobile communication system USSDC and USSD service application. As shown in the figure, the service application interface of the USSD center uses the USSD service application protocol to realize the interaction with the external US...

Abstract

This invention disclosed a method to realize the business transfer among USSD business application. This method is in the protocol of USSD business application interface protocol install the USSD business transfer news which use to business application informs USSDC to transfer business. When user select new USSD business by mobile platform. The present USSD business application transmits business transfer news it include new USSD business application code to USSDC. The USSDC according to this business transfer news to build the conversation of new USSD business application. The above scheme can satisfy the need of among the business applications transfer USSD conversation, can make the business of USSD more nimble and diversified.

Description

technical field [0001] The present invention relates to a method for realizing a service in a communication system, in particular to a method for realizing an Unstructured Supplementary Service Data (USSD, Unstructured Supplementary Service Data) service. Background technique [0002] USSD service, as a supplementary service data service in the Global System for Mobile Communications (GSM) system, is a new service on the mobile network with easy operation and strong service scalability, and can provide more than 98% of the extended data services on the mobile network. Through the USSD service, the user can select a menu on the mobile station and input a short character string to submit a request for obtaining corresponding information. For example, according to the format "*#AAA*BBB#" input string to submit a USSD request to the system, the information provided by the corresponding service can be obtained, where AAA indicates the service number, and BBB indicates the additio...
