Title:

IMS DATA CHANNEL-BASED COMMUNICATION METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/033278

Kind Code:

A1

Abstract:

The present application provides an IMS data channel-based communication method and device. The method may comprise: a certificate management server receives an encrypted bill from an AS and identifier information of a first application; the certificate management server sends the encrypted bill and the identifier information of the first application to a KMS; the certificate management server receives a first key; and the certificate management server sends, to an AS first terminal, a data channel application certificate corresponding to the first key, the data channel application certificate being used for the first application and a second application of a second terminal to perform an IMS data channel service. In the present application, the certificate management server issues a reliable data channel application certificate to the first terminal, and an IMS network can learn the data channel application certificate, thereby preventing the first terminal from manually installing/replacing a third-party (not provided by a communication network) certificate and using an unreliable self-signed certificate, and then providing reliable IMS data channel communication.
