Method, device, and system for user equipment to access evolved packet core network

摘要

A method for a user equipment (UE) to access an evolved packet core (EPC) network includes: receiving, by an EPC access gateway connecting a wireless local area network (WLAN) to an EPC, a Dynamic Host Configuration Protocol (DHCP) request from the UE; and obtaining, by the EPC access gateway, subscription data of the UE according to a media access control MAC address of the UE in the DHCP request, and performing EPC access processing for the UE according to the obtained subscription data, where the obtaining subscription data of the UE according to a MAC address of the UE includes: obtaining the subscription data of the UE according to (a) the MAC address of the UE and (b) a matching MAC address of the UE the subscription data of the UE that are correspondingly stored by a network device in an access authentication process.

1. A method for a user equipment (UE), connected to a wireless local area network (WLAN), to access an evolved packet core (EPC) network, comprising:
receiving, by an EPC access gateway connecting the WLAN to the EPC network, a Dynamic Host Configuration Protocol (DHCP) request from the UE carrying a media access control (MAC) address of the UE; obtaining, by the EPC access gateway, subscription data of the UE from an Authentication, Authorization and Accounting (AAA) server/proxy or a WLAN authenticator according to the MAC address of the UE in the DHCP request, wherein the AAA server/proxy is included in the EPC network and the WLAN authenticator is included in the WLAN; selecting, by the EPC access gateway, an Access Point Name (APN) for the UE based on the obtained subscription data of the UE; selecting, by the EPC access gateway, a public data network (PDN) gateway (PGW) for the UE accessing the EPC network based on the selected APN, wherein the PGW is included in the EPC network and is communicatively coupled to the PDN; and performing, by the EPC access gateway, EPC access processing for the UE according to the selected PGW, wherein access processing includes aggregation of data of the UE.
