Service negotiation method, service negotiation system and communication terminal

Abstract

The invention discloses a service negotiation method, a service negotiation system and a communication terminal. The service negotiation method comprises the steps that: a service initiating terminal establishes a voice call connection with a service receiving terminal; the service initiating terminal generates a first feature voice code according to a communication service to be initiated, and sends the first feature voice code to the service receiving terminal by utilizing the voice call connection for performing service negotiation; the service initiating terminal executes corresponding operation, according to the response, for the first feature voice code, of the service receiving terminal. According to the service negotiation method, the feature voice codes is transferred by utilizing the voice channel of the voice call connection, the service negotiation is performed by the feature voice code, and the communication service is initiated or stopped according to the negotiation result. And therefore, new service development can be performed without modifying the protocol and the framework of a terminal system, development investment is decreased, and development cost is reduced; and every terminal with the voice communication function is applicable, so that compatibility is high.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a service negotiation method, a service negotiation system and a communication terminal. Background technique [0002] When establishing a service connection between two communication terminals such as a mobile phone, service negotiation is generally required, and the existing solutions generally carry out the negotiation through a dedicated protocol and channel. For example, voice connection and data connection need to use dedicated protocols, such as air interface protocols such as GSM, WCDMA, and CDMA, or standard protocols such as TCP / IP, and involve access networks, core networks, and dedicated servers or business centers. [0003] The problem is that when developing new end-to-end services for communication terminals or optimizing existing services, when there is a need for new service negotiation, standard protocol and channel expansion and changes need to involve te...
