Patent ID: 8804562

Claim:
An implementation method of a broadband network system, comprising: a terminal transmitting an IP address request message to a network side; after receiving the IP address request message, the network side returning a non-IP-address Endpoint Identifier (EID) of the terminal; and the terminal using the received EID as an address to transmit and receive packets, wherein the EID of the terminal comprises at least one of: national identification number, passport number, driver's license number, domain name system number, defined numbering system, and telephone number of a user using the terminal, wherein before the terminal transmitting the IP address request message to the network side, the method further comprises: the terminal performing PPP over Ethernet (PPPoE) user authentication with the network side, and passing the authentication; and the terminal using the received EID as the address to transmit and receive the packets comprises: the terminal using the received EID as a source address to perform EID packet encapsulation for service data, performing PPPoE frame encapsulation for the EID-encapsulated packet, and transmitting the PPPoE-encapsulated frame; a Broadband Remote Access Server (BRAS) at the network side analyzing the received PPPoE-encapsulated frame, and searching a Routing Locator (RLOC) address corresponding to a destination EID carried in the analyzed EID-encapsulated packet according to the corresponding relationship of EID/RLOC; and the BRAS performing IP packet encapsulation for the EID-encapsulated packet according to the searched RLOC address, and transmitting the IP-encapsulated IP packet.
