Abstract

Embodiments of the present invention provide a network access method, device, and system. The network access method includes: when a second gateway determines to receive a first packet sent by a terminal device that does not belong to the network segment where the second gateway is located , assign a second Internet Protocol IP address to the terminal device, and obtain the IP address of the first gateway according to the first IP address in the first packet; wherein the first IP address is the same as the first IP address. The gateway is in the same network segment, and the second IP address and the second gateway are in the same network segment; the second gateway assigns the first IP address to the first gateway according to the second IP address and the IP address of the first gateway The message is forwarded to the first gateway to send the first message through the first gateway. The network access method, device and system provided by the embodiments of the present invention are used to adaptively provide a terminal device with a network access service during roaming.

Description

technical field [0001] The embodiments of the present invention relate to network technologies, and in particular to a network access method, device and system. Background technique [0002] Terminal devices can access the network in two ways: a fixed Internet Protocol (IP) address allocation mode and a dynamic IP address allocation mode. In some private networks, in order to meet the needs of network confidentiality and security, the terminal devices in the network are connected to the network by assigning fixed IP addresses. In the network server, the media access control of each terminal device in the network is stored. (Medium Access Control, referred to as MAC) address and the binding relationship of the IP address assigned to it, in order to conduct network authentication, Internet tracking and auditing of terminal equipment. [0003] In the private network, the terminal device is assigned the IP address of the network segment where the first gateway is located when i...
