Method for determining duration of public network access by user terminal and net access server

Abstract

The invention discloses a method for determining duration of public network access by a user terminal and a net access server, so that a problem that a user terminal of a campus broadband can not be distinguished and thus duration of public network access by the user terminal of the campus broadband can not be acquired in the prior art can be solved. The method comprises: a net access server (NAS) receives a data message sent by a user terminal; a destination address carried by the data message and a public network IP address of the user terminal are obtained; whether the destination address is an intranet address is determined and if so, timing is started; a designated operation is executed at each preset receiving cycle until an off-line request sent by the user terminal is received; and the NAS uses the time of reception of the off-line request sent by the user terminal as a timing end time, timing duration is determined and duration of public network access by the user terminal is also determined based on the determined on-line duration.

Description

technical field [0001] The invention relates to the field of broadband access, in particular to a method for determining the duration of a user terminal accessing a public network and a broadband access server. Background technique [0002] At present, in the field of broadband access, there are mainly two types of broadband services for home users and group users. Broadband access for home users usually adopts a point-to-point protocol over Ethernet (PPPoE) authentication method, and broadband access for group users usually uses IPoE authentication. [0003] Based on the PPPoE authentication method, the home broadband users access the broadband access server (Net Access Server, NAS) through the transmission network, and the NAS combines the authentication and billing (Radius) server to complete the PPPoE authentication of the home broadband users, so that the home broadband users can Get a random public IP address. The transmission network mentioned here refers to the sec...
