Problems solved by technology

As can be seen from the above process, with the existing network access method, as long as the user terminal initiates a DHCP request, no matter whether it is an illegal user or a legal user, the DHCP server will assign an IP address to the user, which not only causes a waste of IP addresses, but also creates a problem for illegal users. It provides an opportunity to surf the Internet without authentication and billing. What is more serious is that if illegal users continuously initiate DHCP requests maliciously, all IP addresses in the DHCP server address pool will be exhausted and cannot be controlled. Therefore, the existing network The access method is less secure

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] At present, in broadband access, user terminals generally access the network through Layer 2 switching equipment, and the most common Layer 2 switching equipment supports the 802.1Q protocol (which is formulated by the IEEE (Institute of Electrical and Electronics Realize a standard protocol of virtual local area network) Ethernet Layer 2 switch (LANSWITCH, Local Area Network Switch). All the messages sent by the user terminals connected by LANSWITCH can be added with a special tag for user terminal identification. In practice, the tag can be a VLAN (Virtual Local Area Network: Virtual Local Area Network) tag. A specific physical interface through which the user terminal accesses the LANSWITCH can be uniquely identified. Therefore, the DHCP relay server in the network can use this VLAN tag to implement user authentication and legitimacy check.

Abstract

This invention discloses a broadband network access method, in which DHCP relay server receives the DHCP request message sent by an end user, then to certificate and examine the user according to the message; if the examines is passed, the said DHCP request message is transferred to DHCP server which allocates IP address for the said user end and records the IP address network initialized information in the DHCP response message to be transferred to the user end by DHCP relay server, the user end gets IP address and cuts over into the network; other wise it gives up the said end user DHCP request message and stops the user in the network.

Description

technical field [0001] The invention relates to a wireless network access method, in particular to a broadband wireless network access method. Background technique [0002] In a broadband network, if a user terminal sends a network access request, the server responsible for IP address allocation in the network will assign an Internet (IP) address to the user terminal that sends the network access request, so that the user terminal can access the network. At present, the server in charge of IP address allocation in the broadband network, that is, the DHCP server adopts the standard Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol), so that the user terminal can automatically obtain the IP address from the DHCP server when accessing the network, etc. information. When a user terminal accesses the network, the user terminal first sends a DHCP request message to apply for access to the network. After receiving the request message, the DHCP relay se...
