Abstract: A communication method, user equipment, an access network device, and an application server. The method is: allocating, by the access network device, an IP address to the UE; and after the UE notifies the IP address to the application server, performing, by the application server, a data transmission service for the UE by using the IP address. By using the technical solutions of the present invention, a PDN-GW, an SGW, a PCRF entity, an MME, and an HSS in an existing wireless communications network are deleted, and functions of the foregoing network side devices are implemented by using the access network device and the application server. Therefore, it is avoided that an SGW-to-PDN-GW link becomes a bottleneck of a processing capability of the wireless communications network, network layers are greatly reduced, a data transmission delay is effectively reduced, and a network paralysis risk is reduced.
