Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] The invention provides a method for acquiring NAT information.

[0040] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the method for obtaining NAT information in the present invention.

[0041] In the first embodiment, the method for obtaining NAT information includes:

[0042] Step 101, establishing an intercommunication channel between the broadband remote access server BRAS equipment and the operator-level NATCGN equipment;

[0043] Specifically, the user-related configuration is completed on the broadband remote access server (BroadbandRemoteAccessServer, BRAS) device, and the network address translation (NetworkAddressTranslation, NAT) related configuration is completed on the independent carrier-grade NAT (Carrier-GradeNAT, CGN) device , for example, to configure ...

Abstract

The invention discloses a network address translation (NAT) information acquisition method. The NAT information acquisition method comprises the steps: establishing an intercommunication channel between a broadband remote access server (BRAS) device and a carrier-grade NAT (CGN) device; through the intercommunication channel, receiving NAT information, which is transmitted by the CGN device; transmitting the NAT information to a server, thereby ensuring that a user searches for the NAT information through the server. The invention further discloses a BRAS device. Establishment of a channel, for transmitting associated information, between a distributive BRAS device and an independent CGN device is implemented, so that user-associated NAT information is convenient to be directly acquired at the BRAS device.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for acquiring NAT information and BRAS equipment. Background technique [0002] At present, there are many deployment scenarios for CGN (Carrier-Grade NAT, carrier-grade NAT). One of the deployment scenarios is: Broadband Remote Access Server (Broadband Remote Access Server, BRAS) equipment completes user access, and independent CGN equipment bypasses BRAS The device, or connect to the BRAS device under the CGN, and connect to the Internet on the up. In this scenario, the BRAS device performs the function of user access, while the CGN device performs NAT conversion. BRAS equipment is opposite to CGN equipment. [0003] In the prior art, on distributed BRAS devices, it is impossible to obtain information related to network address translation (Network Address Translation, NAT) of users. Therefore, it is not conducive to user traceability. Contents of the invention [0004]...
