This application provides a data transmission method computer-readable storage medium performed by an electronic device. The method includes: obtaining a latency variation distribution characteristic of a service data packet, the latency variation distribution characteristic being configured for indicating a transmission latency range of the service data packet; detecting a network transmission characteristic between an application server (AS) and a core network gateway; adjusting the latency variation distribution characteristic of the service data packet based on the network transmission characteristic, to obtain an adjusted latency variation distribution characteristic; and transmitting the adjusted latency variation distribution characteristic to a core network element, so that the core network element controls data transmission based on the adjusted latency variation distribution characteristic.
