AI Technical Summary
Technical Problem
Existing Internet Protocol Multimedia Subsystem data channels can only be established within the same operator's network and cannot be established during cross-network calls, resulting in a reduced user experience.
Method used
By querying the operator network identifiers of the called and calling terminals when a call request is received, querying the corresponding media gateways, and applying for data channel resources, data channels across operator networks can be established.
Benefits of technology
Whether it is a call across carrier networks or a call within the same carrier network, data channels can be established smoothly, improving user experience.

Abstract
The present application relates to a method, apparatus, communication equipment, storage medium and computer program product for establishing a data channel. The method comprises: receiving a call request sent by a calling terminal, querying the network identifier of the operator network of the called terminal based on the called terminal's identifier; querying the corresponding media gateway based on the calling terminal's identifier and the called terminal's network identifier; applying for data channel resources from the media gateway, and forwarding the call request to the network device of the operator network of the called terminal based on the application result; when receiving a call request sent by the network device of the operator network, querying the network identifier of the operator network of the calling terminal based on the calling terminal's identifier; querying the corresponding media gateway based on the called terminal's identifier and the calling terminal's network identifier; applying for data channel resources from the media gateway, and forwarding the call request to the called terminal based on the application result. This method can smoothly establish a data channel in the case of cross-network calls or calls on the same network, thereby improving user experience.
