Problems solved by technology
[0003] In related technologies, during the transmission of DTMF signals in two-stage dialing scenarios, DTMF signals are carried in DTMF messages, and the number corresponding to the signal cannot be directly checked from the payload of the DTMF message, but only in the media conversion from the perspective of operation and maintenance. Devices perform end-to-end confirmation on media-level recordings one by one. However, since each conversion point involves equipment from different manufacturers, some equipment manufacturers do not even support media-level recording. Difficult, and the excessive number of media conversions in the whole end-to-end network is likely to cause signal damage, which affects the real effectiveness of the second-stage dialing

The invention relates to the technical field of communication, and relates to a method and system for realizing secondary dialing, a storage medium and electronic equipment. The method comprises the following steps of: acquiring a signaling message of a media gateway control function (MGCF) in an intercommunication secondary dialing process of a voice over long term evolution (VoLTE) network and a circuit switching (CS) network; detecting the signaling message based on a preset cross-domain dual-tone multi-frequency rule, wherein the preset cross-domain dual-tone multi-frequency rule is used for indicating a target dual-tone multi-frequency (DTMF) transmission mode supported by the CS network and a target media network element which does not participate in media conversion in signaling message transmission; and if the signaling message is inconsistent with the preset cross-domain dual-tone multi-frequency rule, correcting the signaling message, so that the signaling message conforms to the cross-domain dual-tone multi-frequency rule. Through detection and error correction of signaling messages of a communication MGCF, only one-time media conversion is carried out in the whole process of secondary dialing in the intercommunication process of a VoLTE network and a CS network, and the success rate of VoLT E secondary dialing is improved.
Description
technical field [0001] The present disclosure relates to the technical field of communication, and more specifically, to a method for realizing two-time dialing, a system for realizing two-time dialing, a computer storage medium, and an electronic device. Background technique [0002] In many business scenarios, users need to interact with the network by pressing buttons on the terminal device (that is, secondary dialing), such as recharging, dialing the switchboard and then dialing the extension number, dialing the customer center number, etc. DTMF (Dual Tone Multi-Frequency, Dual Tone Multi-Frequency) signal is a kind of user signaling between the telephone set and the switchboard in the telephone system. A DTMF signal can be generated by the user pressing a key on the terminal device. [0003] In related technologies, during the transmission of DTMF signals in two-stage dialing scenarios, DTMF signals are carried in DTMF messages, and the number corresponding to the signa...
