AI Technical Summary

Technical Problem

In the context of voice calls or video calls, how the terminal uses the data channel to interact with multimedia information is a technical problem that needs to be solved, especially in scenarios of rich media information interaction.

Method used

By carrying rich media information with indication information for triggering the establishment of the data channel, the terminal can initiate a process of establishing the data channel, thereby using the data channel in the context of rich media information interaction. The method includes receiving rich media information, analyzing the indication information, and initiating a process of establishing a data channel in response to a user operation.

Benefits of technology

It realizes the use of data channels in the context of rich media information interaction, expands the existing RCS protocol, reuses the existing IMS ecosystem, promotes the development and growth of rich media messages, and can still use the services provided by the data channel application after PS data is closed.
