Description

Charging synchronization method, device and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a device for charging synchronization.

Background

BRAS (Broadband Remote Access Server) is a novel Access gateway for Broadband network application. For BRAS equipment, the most important step in promoting its generalized evolution is the separation of forwarding and control.

The basic idea of the transfer control separation BRAS system is as follows: abstracting control surface functions on a plurality of BRAS devices and carrying out centralized cloud deployment to form a uniform BRAS controller (BRAS-CP); meanwhile, the BRAS device or other forwarding devices with the stripped control plane form a BRAS forwarder (BRAS-UP). The diversion separation BRAS system then consists of BRAS-CP and BRAS-UP.

In a BRAS system with separate control, one BRAS controller (C-plane) manages a plurality of BRAS repeaters (U-planes), and the C-plane and the U-plane directly perform information interaction through protocols such as VXLAN (Virtual eXtensible LAN), Openflow (open source), Netconf (network configuration), and the like.

The U plane receives and processes a PPPOE (point-to-point protocol over Ethernet) packet of a user, and then uploads a PPPOE control packet and charging information related to the user to the C plane. The C plane stores and maintains User state information and table entries such as PPPOE state machine, and is responsible for performing message interaction of related Authentication and charging request with AAA (Authentication, Authorization, Accounting, verification, Authorization, and Accounting) server through Radius (Remote Authentication Dial In User Service) protocol.

In a transfer control separation BRAS system, after the communication between a U surface and a C surface is disconnected due to faults, the charging information, offline messages and the like sent to the C surface by the U surface are lost, so that various access information and Log logs of a user are lost, and the charging information is inaccurate.

Detailed Description

The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

As shown in fig. 1, the charging synchronization method according to the embodiment of the present invention is applied to a BRAS controller, and includes:

and step 101, detecting the communication state between the BRAS repeater and the BRAS repeater.

The BRAS controller can periodically detect the communication state between the BRAS controller and the BRAS repeater so as to determine whether the communication connection is maintained.

Step 102, if the communication between the BRAS transponder and the BRAS transponder is interrupted, entering a circular waiting state, and sending a state conversion message to an AAA server to enable the AAA server to enter the circular waiting state.

In the embodiment of the present invention, a state is newly defined, which is referred to as a loop wait state (CRLoop state). In the cyclic waiting state, the BRAS controller keeps all data of the current user from being updated and cleared; and the AAA server keeps all data of the current user from updating and clearing, and suspends charging.

In the prior art, a Radius message structure is shown in fig. 2. Wherein:

code: indicating a packet type; 1 byte; indicating the type of RADIUS packet.

An Identifier: indicating a package identification; 1 byte; the identifiers for matching request packets and response packets should be the same for the same group of request packets and response packets.

Length: indicates the packet length; 2 bytes; the length of the entire packet.

The activator: representing a verification word; 16 bytes; for signing the package.

The Code field length is 1 byte, and is used for marking the type of the RADIUS message. The Code domains are 1, 2, 3, 4, 5 more common. A value of 1 indicates that the message type is an authentication request, a value of 2 indicates that the message type is an authentication accept, a value of 3 indicates that the message type is an authentication reject, a value of 4 indicates that the message type is a charging request (start/update/stop), and a value of 5 indicates that the message type is a charging response (start/update/stop).

In the embodiment of the invention, the Radius message is expanded, and the expanded Radius message is used for communicating with the AAA server.

Specifically, the BRAS controller sends a Radius message to the AAA server, and notifies the AAA server area of a circular waiting state. And the packet type of the Radius message is a first preset value. Wherein the first preset value may be 15.

In addition, in order to enable the AAA server to finish charging and offline the user by the AAA server no matter whether the BRAS controller sends an update notice to the AAA server or not, so as to avoid the user from being kept in a CRLoop state without limit, if the communication between the BRAS controller and the BRAS repeater is interrupted, the BRAS controller can also send state keeping duration to the AAA server. Wherein the duration can be set arbitrarily.

The structure of the expanded Radius message is shown in fig. 3. As illustrated in fig. 3, where Code 15. Meanwhile, an attribute 85 in this message has a value of Max CRLoop time, which is used to indicate the state holding time.

Step 103, if the communication between the BRAS transponder and the BRAS transponder is recovered, obtaining the user state information and the user charging information sent by the BRAS transponder, updating the stored user data according to the user state information and the user charging information, and informing the AAA server of charging.

In this step, the BRAS controller acquires a subscriber who is on-line and a subscriber who is off-line during a communication interruption with the BRAS repeater, according to the subscriber status information. For the online user, the BRAS controller sends a Radius accounting request updating message to the AAA server, where the accounting request updating message is used to update the accounting information of the online user to the AAA server, so that the AAA server switches from a loop waiting state to an accounting state, and accounts for the online user. For the offline user, the BRAS controller sends a Radius accounting request ending message to the AAA server, wherein the Radius accounting request ending message is used for informing the AAA server to end the accounting of the offline user, and the BRAS controller is switched from a circulating waiting state to a user offline state.

The packet types of the Radius charging request update packet and the Radius charging request end packet are a second preset value, for example, a value of 4 may be taken. The structures of the Radius charging request update message and the Radius charging request end message are shown in fig. 4(a) and fig. 4 (b). The Radius charging request updating message and the Radius charging request ending message can be distinguished through a combined attribute domain.

For example, as shown in fig. 4(a), the attribute 40, the value is 3; as shown in fig. 4(b), the attribute 40 of the Radius charging request end packet has a value of 2.

As shown in fig. 5, the charging synchronization method according to the embodiment of the present invention is applied to a BRAS repeater, and includes:

step 501, detecting the communication state between the BRAS controller and the BRAS controller.

The BRAS repeater can periodically detect the communication state between the BRAS repeater and the BRAS controller to determine whether the communication connection is maintained.

Step 502, if the communication between the BRAS controller and the BRAS controller is interrupted, user state information and user charging information during the communication terminal with the BRAS controller are obtained.

Specifically, in this step, the BRAS repeater records, for a user who is online during a communication interruption period with the BRAS controller, a time of the communication interruption between the online user and the BRAS controller, and stores and maintains real-time charging information of the online user; and for the user who is offline during the communication interruption period between the user and the BRAS controller, processing the offline control message of the user who is offline, and recording the offline duration and the flow charging information.

Step 503, if the communication between the BRAS controller and the user is recovered, sending the user state information and the user charging information to the BRAS controller.

In the embodiment of the invention, when the communication between the BRAS repeater and the BRAS controller is interrupted, the BRAS controller and the AAA server enter a circular waiting state; in the cyclic waiting state, the BRAS controller keeps all data of the current user from being updated and cleared; the AAA server keeps all data of the current user not to be updated or reset, and suspends the charging. When the communication between the BRAS repeater and the BRAS controller is recovered, the BRAS controller updates according to the user state information and the user charging information sent by the BRAS repeater, and the AAA server performs charging. Therefore, the scheme of the embodiment of the invention can ensure that various information of the user can be still saved even when the communication between the BRAS repeater and the BRAS controller is interrupted, and the charging is carried out when the communication is recovered, thereby ensuring the accuracy of the charging information.

As shown in fig. 6, the accounting synchronization method according to the embodiment of the present invention is applied to an AAA server, and includes:

step 601, when the communication between the BRAS controller and the BRAS transponder is interrupted, receiving a state switching message of the BRAS controller, and entering a circular waiting state according to the state switching message.

And the AAA server receives a Radius message sent by the BRAS controller, wherein the packet type of the Radius message is a first preset value. Wherein, the first preset value may be 15. The structure of the Radius message is shown in fig. 3. And in the circular waiting state, the AAA server keeps all data of the current user from updating or clearing, and suspends the charging.

In addition, in order to enable the AAA server to finish charging and offline the user by the AAA server no matter whether the BRAS controller sends an update notice to the AAA server or not, so as to avoid the user from being kept in a CRLoop state without limit, if the communication between the BRAS controller and the BRAS repeater is interrupted, the BRAS controller can also send state keeping duration to the AAA server. Wherein the duration can be set arbitrarily. Correspondingly, when the communication between the BRAS controller and the BRAS transponder is interrupted, the AAA server receives the state holding time length sent by the BRAS controller, and when the time for entering the circular waiting state exceeds the state holding time length, the AAA server finishes the charging.

Step 602, when the communication between the BRAS controller and the BRAS repeater is recovered, charging is carried out according to the notice of the BRAS controller.

For the online user during the communication interruption between the BRAS controller and the BRAS transponder, the AAA server receives a Radius charging request updating message sent by the BRAS controller and charges the online user according to the Radius charging request updating message;

for the user who is offline during the communication interruption between the BRAS controller and the BRAS transponder, the AAA server receives a Radius charging request ending message sent by the BRAS controller, ends the charging of the user who is offline according to the Radius charging request ending message, and switches from a circular waiting state to a user offline state.

The packet types of the Radius charging request update packet and the Radius charging request end packet are a second preset value, for example, 4. The structures of these two messages can be referred to the aforementioned fig. 4(a) and fig. 4 (b).

In the embodiment of the invention, the functions of the BRAS repeater and the BRAS controller of the control separation BRAS and the Radius protocol are expanded, so that the charging information and the user state synchronization capacity during the communication interruption between the BRAS repeater and the BRAS controller and after the communication is recovered are improved.

1. After communication interruption between the BRAS repeater and the BRAS controller:

the BRAS repeater keeps the current online user alive and maintains the user charging information; and processing the control message and recording the charging information for the user applying for offline during the communication interruption period, and approving the user offline.

The BRAS controller and the AAA server both enter a CRLoop state, all data of the current user are kept not to be updated or cleared, and the AAA server suspends the charging.

2. After communication between the BRAS transponder and the BRAS controller is recovered:

the BRAS repeater updates the subscriber information to the BRAS controller. And the BRAS controller updates information to the AAA server, and jumps out of the CRLoop state with the AAA server to restart normal charging.

As shown in fig. 7, the charging synchronization method according to the embodiment of the present invention specifically includes:

step 701, the BRAS controller sends an authentication request packet to the Radius server.

Step 702, the Radius server sends an authentication acceptance packet to the BRAS controller.

Step 703, the BRAS controller sends a charging start request packet to the Radius server.

Step 704, the Radius server sends the accounting start request response packet to the BRAS controller.

Step 705, if the communication between the BRAS controller and the BRAS repeater is interrupted, the BRAS controller notifies the Radius server that the charging is suspended, and the state of CRLoop is entered.

If the BRAS repeater finds that normal communication with the BRAS controller cannot be achieved through a keep-alive mechanism between the C/U, the BRAS repeater keeps the current user still on line, starts to record the time of communication disconnection with the BRAS controller, and stores and maintains real-time charging information of the online user (a CP is not required to reply a charging response message). The BRAS transponder processes the user offline control message for the user applying offline during the communication interruption period, and records corresponding duration and flow charging information.

Step 706, if the communication between the BRAS controller and BRAS repeater is recovered, the BRAS repeater sends the stored subscriber status and billing information to the BRAS controller.

And step 707, the BRAS controller processes the charging and user state information during the communication interruption, and sends the information to the Radius server to inform the Radius server to recover the normal charging.

In the process, if the communication between the BRAS controller and the BRAS transponder is recovered, the U plane collects the user charging information and the state information and sends the user charging information and the state information to the C plane, and the C plane updates the related information. And the C surface updates the charging information and the state information of each user to the AAA server, informs the AAA server to change the CRLoop state and restarts normal charging.

After the communication between the BRAS controller and the BRAS transponder is recovered, the BRAS controller updates the accounting information to the AAA server for the user still on line, and informs the AAA server to switch from the CRLoop state to the normal accounting state. When the communication between CUs is interrupted, the BRAS controller sends an accounting request ending message to the AAA server to inform the AAA server to end accounting, and the CRLoop state is switched to the user offline state.

Step 708, the BRAS controller sends a charging end request packet to the Radius server.

Step 709, the Radius server sends a charging end request response packet to the BRAS controller.

In the embodiment of the invention, in consideration of a novel device form separated from BRAS transfer control and a novel data interaction form between devices, a new synchronization mechanism and a new synchronization state are introduced into a protocol stack and a Radius protocol on the devices, so that the reliability of user data storage and transmission is enhanced.
