Abstract

The embodiment of the invention discloses an in-band number receiving method, which comprises the following steps: during the subscriber communication process, receiving messages which are sent by an application server, and contain the service access codes of the in-band DTMF service; receiving subscriber in-band dialing information and matching the subscriber in-band dialing information with theservice access codes of the in-band DTMF service sent by the application server, if the matching is done, sending the in-band dialing information to the application server. In the embodiment of the invention, a service control network element AS sends numeral and picture information required by the service, an access network element or an access terminal sends numerals and pictures to a media network gateway which is matched with the subscriber in-band dialing information according to the numeral and picture information, therefore, the report is required only when the matching is done, so as to reduce the potential safety hazard.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, system and equipment for in-band number collection. Background technique [0002] At present, many services use in-band DTMF (Dual Tone Multi Frequency) detection. The detection method is through the terminal or access network element detection, and then reported to the AS (Application Server, application server) for processing. [0003] In the prior art, after the terminal or the access network element detects the user's in-band dialing information, it reports to the AS bit by bit in an out-of-band manner. In the SIP protocol, the INFO method can be used to transmit the DTMF signal. When the AS needs to provide the service of detecting in-band DTMF signaling, it is generally determined by the configuration of the access network element or the terminal, and all the in-band dialing information of the user is reported to the AS bit by bit through INFO.
