Embodiment Construction

[0034] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0035] The invention expands the INFO message of the standard SIP protocol, so that the SIP server can instruct the IWU to detect the button event of the communication state terminal by extending the INFO message. Concretely, by expanding the message header and the message body of the standard INFO message, make it play the effect of indicating button detection: the present invention expands the Content-Type (representing message type) field in the INFO message header to application / X, Wherein application represents that this INFO message is an extended INFO message, and the parameter indicated by X is the concrete type of this extended INFO message, and this type can be customized as required. Preferably, the present invention sets the X field to number (digits); in addition , in the message body of INFO message amo...

Abstract

The invention discloses a method for carrying out key detection and number receiving on a terminal in conversation state and the terminal enters the conversation state. The method comprises: a protocol interworking unit (IWU) receives an extension INFO message for starting the key detection sent by a session initiation protocol (SIP) server; the key detection and the number receiving are carried out on the terminal in conversation state according to the message; the SIP server receives the extension INFO message of successful number receiving sent by the IWU after the IWU completes the key detection and the number receiving; when the SIP server determines that a key symbol of detection and number receiving carried in the extension INFO message of successful number receiving is consistent with the key symbol to be detected, the business indicated by the key symbol of detection and number receiving is implemented. The invention further discloses a system for carrying out the key detection and the number receiving on the terminal in conversation state, and the problem that the SIP server can not instruct the IWU to acquire the key event of the terminal in conversation state can be solved based on the method and the system.

Description

technical field [0001] The present invention relates to the technical field of button detection, in particular to a method and system for detecting buttons and collecting numbers on a terminal in a talking state. Background technique [0002] In the next generation network (NGN, Next Generation Network), operators are more and more inclined to separate the basic communication function and service processing function: use the protocol interworking entity (IWU, InterworkingUnit) to realize the basic communication function; use the session initiation protocol ( A SIP (Session Initiation Protocol) server, such as an application server (AS, Application Server), processes services, and a standard SIP protocol is used for communication between the IWU and the SIP server. In this way, operators can add new services more conveniently, which is conducive to improving their competitiveness. [0003] In the prior art, the IWU can control the media gateway (MG, Media Gateway) to detect ...
