Problems solved by technology

After the user obtains the A address, and an illegal message with the original A address is triggered on the other side where the BRAS enables unknown source access, the BRAS will understand that the user has roamed here, and then transfer the previous DHCP The session goes offline. In this way, the DHCP access side has the threat of receiving an attack and going offline.
[0010] However, if the user holding the IP accesses on the other side through an interface or subnet leased line, the original DHCP user will not be kicked offline, and the billing of the original user will continue

Embodiment

[0029] Embodiment: the present invention is a kind of IPoE roaming session control method comprising the following steps:

[0030] The specific implementation is as follows:

[0031] 1) BRAS adds roaming policy and roaming policy control enabling functions. After it is enabled, when the BRAS judges that a user meets the roaming conditions, it will match the roaming policy.

[0032] 2) The roaming policy has three columns, which are the user type before roaming, the user type after roaming, and the session control action. For example, user types include DHCP / unclassified-ip / interface-leased / subnet-leased / DHCPv6 / unclassified-ipv6 / ndrs, etc.; session control actions include: direct migration (direct) / session remain unchanged / original user goes offline (Log Off) / trigger ICMP Echo / match specific user session migration control list, etc. For example, as shown in Table 1 below (not limited to Table 1)

[0033] Table 1

[0034] User type before roaming User type after ...

Abstract

The invention discloses an IPoE roaming session control method, which includes the steps of matching the corresponding strategy from the roaming control strategy when a certain side of the BRAS receives the same flow or online trigger request as the existing session IP. The beneficial effect of the invention is that the operator can flexibly customize the roaming strategy according to user requirements.

Description

technical field [0001] The invention belongs to the field of roaming control, and specifically refers to an IPoE roaming session control method. Background technique [0002] IPoE (IP over Ethernet) is a common IPoX access method. It performs authentication directly based on the user's access location or message feature information, without the need for the user to install client software and dial-up. After successful authentication, the user can directly access the external network. network. [0003] In today's era of mobile roaming, more and more mobile terminals may access from point A and continue to go online after moving to point B. If you need to re-dial every time, it will greatly increase the cost and pressure of the operator; and repeated dial-up authentication is required, and the customer experience is not good; what's more, in the transition zone of two provinces, the two signals overlap each other , there may be multiple repeated redials, which seriously affe...
