Problems solved by technology

[0007] However, for the method of assigning IPv6 addresses through SLAAC, SLAAC uses the IPv6 ND (Neighbor Discovery) protocol to assign addresses to IPv6 hosts. At present, most ND protocol stacks do not define options similar to DHCP's Option82 and Option60. And most AN devices do not support these option processing for the ND protocol
[0008] Then when IPoE dual-stack, IPv4 is connected first, BNG can still

Embodiment 1

[0066] This embodiment describes the process in which an IPoE dual-stack user goes online, IPv4 first obtains an address, and the user host then requests to access IPv6 through SLAAC, as shown in image 3 shown, including the following steps:

[0067] Step 301, the IPoE dual-stack user host is turned on, and first performs IPv4 access;

[0068] Step 302, the user host obtains an IPv4 address through DHCP, BNG allows the user host to obtain the address, and obtains the Option82 option and Option60 option in the DHCP message, assembles the user name and password of the IPoE user, and sends it to the operator together with the location information of the user access The provider's authentication server authentication authorization;

[0069] Step 303, the authentication is successful, and the IPoE dual-stack user host IPv4 access is successful;

[0070] Step 304, the IPoE dual-stack user host accesses through SLAAC IPv6;

[0071] Step 305, BNG checks that the user host is an IP...

Embodiment 2

[0073] This embodiment describes the process in which an IPoE dual-stack user goes online. The user host first requests to access IPv6 through SLAAC, and then requests to access IPv6 through DHCP. For example, Figure 4 shown, including the following steps:

[0074] Step 401, the IPoE dual-stack user host is turned on, and first performs IPv6 access;

[0075] Step 402, the user host obtains an IPv6 address through the SLAAC request, the BNG check finds that the user host is an IPoE dual-stack user host, and the BNG check finds that the user host has not successfully accessed through IPv4;

[0076] Step 403, BNG rejects the IPv6 access of the user host, and records that the IPoE dual-stack user host once requested IPv6 access and was rejected;

[0077] Step 404, the user host obtains the IPv4 address through DHCP, BNG allows the user host to obtain the address, and obtains the Option82 option and Option60 option in the DHCP message, assembles the user name and password of the ...

Embodiment 3

[0081] This embodiment describes the process in which an IPoE dual-stack user goes online, the user host first requests to access IPv6 through SLAAC, and then does not request to access IPv4 for a long time, as shown in Figure 5 shown, including the following steps:

[0082] Step 501, the IPoE dual-stack user host is powered on, and first performs IPv6 access;

[0083] Step 502, the user host obtains an IPv6 address through the SLAAC request, the BNG check finds that the user host is an IPoE dual-stack user host, and the BNG check finds that the user host has not successfully accessed through IPv4;

[0084] Step 503, BNG rejects the IPv6 access of the user host, and records that the IPoE dual-stack user host once requested IPv6 access and was rejected;

[0085] Step 504, within a predetermined time, the user host does not request IPv4 access;

[0086] Step 505, the BNG deletes the user information of the user, and clears the flag indicating that the IPoE dual-stack user hos...

Abstract

The invention discloses a method and a gateway for controlling accessing of a host of an IPoE (IP over Ethernet) dual-stack user, avoiding the problem that a BNG (Broadband Network Gateway) is incompatible in access treatment of the host of the IPoE dual-stack user based on IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6). The method comprises the step of: once the host of the IPoE dual-stack user is accessed based on the IPv6, determining whether the host of the IPoE dual-stack user is successfully accessed based on IPv4 through the BNG, wherein the host of the IPoE dual-stack user just can be allowed to access based on IPv6 by the BNG only when the host of the IPoE dual-stack user is accessed based on IPv4. The gateway comprises a determining module and an accessing control module. By adopting the method provided by the embodiment of the invention, the BNG can actively suppress the process of accessing based on IPv6 to gain an address when the host of the IPoE dual-stack user is accessed to the BNG, and the address is not gained based on the accessing under IPv4, so that the problem that the BNG is incompatible in access treatment of the host of the IPoE dual-stack user based on IPv4 and IPv6 can be avoided.

Description

technical field [0001] The mobile communication system of the present invention specifically relates to an IPoE (IP over Ethernet, Ethernet carrying IP protocol) dual-stack user host access control method and gateway. Background technique [0002] A dual-stack network means that the Internet provides both IPv4-based network services and IPv6-based network services. The IPoE dual-stack user host means that the user host obtains an IPv4 or IPv6 address at the same time, the user host obtains an IPv4 address through DHCP (Dynamic Host Configuration Protocol), and obtains an IPv6 address through SLAAC (Stateless Address Assignment) or DHCPv6. In this way, during the network transition from IPv4 to IPv6, user hosts can access both the IPv4 network and the IPv6 network at the same time. The dual-stack address of the IPoE dual-stack user host is uniformly allocated by the BNG (Broadband Network Gateway), and the BNG considers that a dual-stack user is a user with both IPv4 and IPv...
