Embodiment Construction

[0065] The present invention will be further introduced below in conjunction with the drawings and specific embodiments.

[0066] The embodiment of the present invention provides a DHCP authentication method, such as figure 2 As shown, it includes the following steps:

[0067] Step s201, receiving a message indicating an authentication method sent by a DHCP client;

[0068] Step s202, sending an authentication request message to the DHCP client according to the above authentication method;

[0069] Step s203, receiving an authentication reply message from the DHCP client to the above authentication request message;

[0070] Step s204: Send a message carrying the authentication result obtained after the authentication reply message is authenticated to the DHCP client.

[0071] By adopting the method provided by the embodiment of the present invention, the authentication request message and the authentication reply message are exchanged according to the authentication method suppor...

Abstract

The invention discloses DHCP authentication method, device and system. The method comprises: receiving message for designating authentication method sent by DHCP client; sending authentication request information according to the authentication method, receiving authentication answer message for authentication request message from DHCP client, sending authentication result message for authenticating the authentication answer message. The inventive example interacts authentication request message and authentication answer message according to authentication method supported by DHCP client, extends authentication message type to promote authentication reliability and safety.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a DHCP authentication method, device and system. Background technique [0002] In the past mobile network applications, the IP addresses of network elements such as BS (Base Station) and some communication entities when they access the network, such as the IP addresses of gateways (GW) The operator manually configures it, which requires the on-site operator to have certain professional technical knowledge. [0003] With the development and expansion of mobile networks, BS equipment has also developed from traditional macro base stations to micro base stations and home base stations. Therefore, the demand for such BS equipment is increasing in the hundreds, and at the same time customers or users request to buy back This kind of equipment can be plug and play, so that the traditional on-site technical personnel manually configure the IP address and other methods can not meet the m...
