Specifically, when the service type is voice group, the target group is determined not to satisfy the resource change condition, when the service type is video group or voice + video group, the target group is determined to satisfy the resource change condition,
s302: and if so, the second cluster core network sends a resource negotiation instruction to the first cluster core network.
In this embodiment, the resource negotiation instruction carries resource change information. For example, the resource change information is to reduce the resolution of the video from the 1080P format to the CIF format.
