Abstract

The present disclosure provides a communication method and an edge access control device, and relates to the technical field of communication. The communication method includes: receiving a calling request message from a VoLTE mobile terminal, wherein the calling request message includes a called number, a first contact address parameter and a first SDP parameter; judging whether the called terminal is based on the called number is a fixed network terminal; when the called terminal is a fixed network terminal, modify the first contact address parameter in the calling request message to a second contact address parameter that can be processed by the fixed network terminal, and the calling modifying the first SDP parameter in the call request message to a second SDP parameter that can be processed by the fixed network terminal; and sending the call request message including the second contact address parameter and the second SDP parameter to the called terminal . The present disclosure can make the call between the calling VoLTE mobile terminal and the called fixed network terminal succeed.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a communication method and an edge access control device. Background technique [0002] VoLTE (Voice over Long Term Evolution, voice service based on long-term evolution) technology is an IP (Internet Protocol, network protocol) data transmission technology that can provide high-quality audio and video calls. With the development of technology, for example, the commercial use of China Telecom's VoLTE has entered the countdown. However, a call failure occurs between the VoLTE mobile terminal and some fixed network terminals (such as a fixed network IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) terminal) during the joint debugging test. Contents of the invention [0003] A technical problem solved by the embodiments of the present disclosure is: in the related art, there is a problem of call failure between a VoLTE mobile terminal and some fixed netwo...
