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, and guide the user to access the required service application through the USSD service menu. When the selected service application no longer meets the needs, it can also return to the The first-level business menu selects other business applications again. A basic requirement to meet this requirement is that after the USSDC establishes a session with a certain USSD service application, the service application can also transfer the session to other USSD service applications. This is the problem to be solved by the present invention.

[0023] figure 1 It is the interface model diagram of 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 USS...

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 invention relates to a service realization method in a communication system, in particular to a realization method of an Unstructured Supplementary Service Data (USSD, Unstructured Supplementary Service Data) service. Background technique [0002] As a supplementary service data service in the Global System for Mobile Communications (GSM) system, the USSD service 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 enter a short string to submit a request to obtain the corresponding information. For example, input a string in the format "*#AAA*BBB#" and submit a USSD request to the system to obtain the information provided by the corresponding service, where AAA represents the service number and BBB represents the additional parameters of the required ...
