METHOD AND DEVICE FOR PROVIDING USER INFORMATION TO CGN DEVICE

Description

TECHNICAL FIELD

The present disclosure relates to the field of communications technologies, and in particular, to a method and apparatus for providing user information to a CGN device.

BACKGROUND

A carrier grade network address translation (CGN, Carrier Grade NAT) device is deployed in a carrier network, which improves smooth transition from Internet Protocol version 4 (IPv4, Internet Protocol Version 4) to Internet Protocol version 6 (IPv6, Internet Protocol Version 6) and promotes the evolution by integrating multiple evolution mechanisms including tunnel and network address translation (NAT, Network Address Translation).

A broadband remote access server (BRAS, Broadband Remote Access Server) device is a new access gateway oriented towards a broadband network application, it is located at an edge layer of a backbone network, and may complete data access of the broadband network of a user. The BRAS device mainly completes functions in two aspects. The first aspect is a network bearer function, for example, the functions of terminating a point to point protocol over Ethernet (PPPoE, Point to Point Protocol over Ethernet) connection of a user terminal, sending a domain name and a password of a user to a remote authentication dial in user service (RADIUS, Remote Authentication Dial In User Service) server for authentication, and converging the traffic of the user terminal. The second aspect is a control implementation function, for example, the function of implementing authentication, charging, and management of access of a user terminal in coordination with an authentication system, an accounting system, a customer management system, and a service policy control system.

In the prior art, a CGN device and a BRAS device are completely independent from each other, between which no information can be transferred. Because the information such as a user name, a password, and a user domain are stored in the BRAS device, the CGN device does not have the information such as the user name, the password, and the user domain. As a terminal of a dual stack lite (DS Lite, Dual Stack Lite) tunnel, the CNG device can identify a user based on only an IPv6 address. In fact, usually an IPv6 address is randomly allocated to a user, and relevant information of the user cannot be obtained from the IPv6 address. Therefore, the CGN device can perform simple management based on only the information such as a virtual local area network (VLAN, Virtual Local Area Network) and an IP address, and cannot perform user-based network management.

DESCRIPTION OF EMBODIMENTS

Embodiments of the present disclosure provide a method and device for providing user information to a CGN device, so as to provide user information to the CGN device and enable the CGN device to perform user-based network management.

To make the objectives, features, and advantages of the present disclosure clearer and more comprehensible, the following describes the technical solutions in the embodiments of the present disclosure in detail with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part rather than all of the embodiments of the present disclosure of the disclosure.

Embodiment 1

According to an embodiment of the present disclosure, a method for providing user information to a CGN device may include: receiving, by a RADIUS server, accounting start request information of a user sent by a BRAS device, where the accounting start request information carries user information of the user; and sending, by the RADIUS server, the user information to a CGN device.

Referring to FIG. 1, the method for providing user information to a CGN device may include the following steps:

101: A RADIUS server receives accounting start request information of a user sent by a BRAS device, where the accounting start request information carries user information of the user.

In the embodiment of the present disclosure, after a user inputs a user name and a password and a BRAS device sends access-request information (access-request) to a RADIUS server according to the acquired user name and password, the RADIUS server performs comparative analysis on the user information and users (users) database information. If authentication is successful, the RADIUS server sends access-accept response information (access-accept) to the BRAS device, indicating that the user has an access right. Next, the BRAS device permits the access of the user according to a received authentication result, sends the accounting start request information (accounting-request) to the RADIUS server, and the RADIUS server may receive the accounting start request information of the user sent by the BRAS device. The accounting start request information carries the user information of the user. In the embodiment of the present disclosure, the user information may be various information required by the CGN device to perform user-based network management. The user information may include: content such as a user identity and management information of the user. The user identity is visible information used to identity different users in various packets. The user identity may specifically include one or more of the following: a user name, a user password, a user type, a user IP address, a user media access control (MAC, Media Access Control) address, user location information, and other specific identities of the user. The management information may include one or more of the following: user bandwidth, a user access right, a user priority, a user online duration, user traffic, user reliability, and user IP address allocation.

In the prior art, there is no user information on the CGN device, and therefore the CGN device cannot perform user-based network management. As a terminal of a dual stack lite tunnel, the CGN device can identify the user based on only an IPv6 address. In fact, usually an IPv6 address is randomly allocated to a user, and relevant information of the user cannot be obtained from the IPv6 address. Therefore, the CGN device can perform simple management based on only information such as VLAN and an IP address, and cannot perform user-based network management.

102: The RADIUS server sends the user information to the CGN device, so that the CGN device is capable of performing network management on the user according to the user information.

After the RADIUS server receives the accounting start request information of the user sent by the BRAS device, because the accounting start request information carries the user information of the user, the RADIUS server is capable of acquiring the user information of the user through the accounting start request information. Next, the RADIUS server sends the user information to the CGN device. Therefore, the CGN device is capable of performing network management on the user according to the user information after receiving the user information. The user information includes the management information of the user. The management information of the user is specific content and a management form of network management to be performed by the

CGN device, where specific implementation may be specified by the user, or may be decided by a mobile carrier.

The CGN device may specifically perform the following network management according to the user information:

1. user management: including the management of: user bandwidth, a user access right, a user priority, a user online duration, user traffic, user reliability, and user IP address allocation; and

2. NAT management: including the management of: public network address planning of the user, the number of public network sessions (session) of the user, a public network address lease of the user, public network traffic bandwidth control of the user, NAT application layer gateway (ALG, Application Layer Gateways) configuration of the user, a NAT log transmission period of the user, and NAT reliability of the user.

It can be seen from the foregoing that, in the embodiment of the present disclosure, a RADIUS server receives accounting start request information of a user sent by a BRAS device, where the accounting start request information carries user information of the user, and then the RADIUS server sends the user information to the CGN device. The accounting start request information of the user received by the RADIUS server carries the user information of the user, and the RADIUS server is capable of sending the user information of the user to the CGN device. Therefore, the CGN device is capable of performing network management on the user according to the user information after receiving the user information.

Embodiment 2

To better understand the technical solutions of the embodiments of the present disclosure, the technical solution in the embodiment of the present disclosure is described in further detail with a more specific example in the following.

Referring to FIG. 2, a method for providing user information to a CGN device may include the following steps:

201: A RADIUS server receives accounting start request information of a user sent by a BRAS device, where the accounting start request information carries user information of the user.

In the embodiment of the present disclosure, after a user inputs a user name and a password and a BRAS device sends access-request information to a RADIUS server according to the acquired user name and password, the RADIUS server performs comparative analysis on the user information and users (users) database information. If authentication is successful, the RADIUS server sends access-accept response information to the BRAS device, indicating that the user has an access right. Next, the BRAS device permits the access of the user according to a received authentication result, sends the accounting start request information to the RADIUS server, and the RADIUS server may receive the accounting start request information of the user sent by the BRAS device. The accounting start request information carries the user information of the user. In the embodiment of the present disclosure, the user information is various information required by the CGN device to perform user-based network management. The user information includes: content such as a user identity and management information of the user. The user identity is visible information used to identity different users in various packets.

It should be noted that, the content of the management information of the user differs with actual implementation scenario, and it is merely an example for illustration, which is not used as limitation.

202: The RADIUS server sends a change of authenticator request message to the CGN device, so that the CGN device is capable of performing network management on the user according to the user information, where the change of authenticator request message carries the user information of the user.

After the RADIUS server receives the accounting start request information of the user sent by the BRAS device, because the accounting start request information carries the user information of the user, the RADIUS server is capable of acquiring the user information of the user through the accounting start request information. Next, the RADIUS server sends the change of authenticator request (CoA, Change of Authenticator) message to the CGN device, where the change of authenticator request message carries the user information of the user. In specific and actual implementation, the RADIUS server may use an existing RADIUS packet, which is shown in FIG. 3 in which a RADIUS packet format is shown. In the RADIUS packet, a packet in which the value of a Code domain is 43 is used as follows:

It should be noted that, in actual implementation, the user information of the user may also be sent to the CGN device in other manners, for example, by using a new protocol interface which is extended.

Therefore, the CGN device is capable of acquiring the user information of the user after receiving the change of authenticator request message, and performing network management on the user according to the user information, where the user information includes the management information of the user. The management information of the user is specific content and a management form of network management to be performed by the CGN device, where specific implementation may be specified by the user, or may be decided by a mobile carrier, and the specific network management performed by the CGN device includes:

1. user management: including the management of: user bandwidth, a user access right, a user priority, a user online duration, user traffic, user reliability, and user IP address allocation; and

2. NAT management: including the management of: public network address planning of the user, the number of public network sessions of the user, a public network address lease of the user, public network traffic bandwidth control of the user, NAT ALG configuration of the user, a NAT log submission period of the user, and NAT reliability of the user.

It can be seen from the foregoing that, in the embodiment of the present disclosure, a RADIUS server receives accounting start request information of a user sent by a BRAS device, where the accounting start request information carries user information of the user, and then the RADIUS server sends a change of authenticator request message to a CGN device, where the change of authenticator request message carries the user information of the user. The accounting start request information of the user received by the RADIUS server carries the user information of the user, and the RADIUS server is capable of sending the user information to the CGN device through the change of authenticator request message. Therefore, the CGN device is capable of performing network management on the user according to the user information after acquiring the user information.
