METHOD, DEVICE, AND SYSTEM FOR UE ACCESS TO EVOLVED PACKET CORE NETWORK

摘要

The embodiments of the present invention provide a method, device, and system for UE access to an evolved packet core network (EPC). The method for UE access to an EPC comprises: a wireless local area network (WLAN) and an EPC access gateway of the EPC are connected to receive a dynamic host configuration protocol (DHCP) request from a UE; the EPC access gateway obtains the subscription data of the UE according to the media access control (MAC) address of the UE in the DHCP request, and performs EPC access processing for the UE according to the obtained subscription data; the obtaining of the subscription data of the UE according to the UE MAC address comprises: obtaining the subscription data of the UE according to the UE MAC address, and the UE MAC address and the UE subscription data stored correspondingly on a network device during the access authentication process. The embodiments of the present invention enable UE access to EPC networks, and reuse the devices in the existing WLAN networks, thereby lowering the upgrade cost of WLAN networks.
