Preferred embodiment of the invention

 The core idea of the present invention is to insert a bearer control layer between the bearer layer and the application layer, and deploy a Broadband Policy System (BPS) to support network users to switch network bandwidth services independently and without service interruption. And the system acts as an adapter for RADIUS (Remote Authentication Dial-in User Service) and BAS (Broadband Access Server) devices. It can adapt the packet attributes of RADIUS and BAS devices of different vendors to let them Linkage.

 The technical solution of the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

 1 is a schematic diagram of a system for dynamically adjusting bandwidth services according to the present invention. As shown in the figure, the system of the present invention can be divided into: a bearer layer, a bearer control layer, and an application layer.

 The bearer layer consists of bearer network devices (eg, BAS devices) responsible for data forwarding. The BAS device obtains and implements a user- and service-based network policy from the BPS through a COA (Change-of-Authorization) command.

 The application layer is a RADIUS server that provides AAA services.

The bearer control layer is a broadband policy system, and the BPS may include: a broadband policy gateway 101, a broadband policy server 102, a broadband policy multi-service management module 103, and a broadband policy WEB server 104. The BPS actively acquires, passively receives, or transparently captures various key information in the network according to a communication protocol such as a RADIUS protocol, a Simple Object Access Protocol (SOAP), or an HTTP (Hyper Text Transfer Protocol). Combined with the pre-configured strategy, the individual access rights, individual service quality, and overall service quality decisions in the auxiliary network are determined by the user, the service can be distinguished, the network can be managed, and the quality can be controlled. The following describes the functions of each unit of BPS:

 The broadband policy gateway performs authentication request and forwarding through the SOAP protocol interface, and the service query management requests and processes the online service switching request and forwarding. The Broadband Policy Gateway is the entry point for BPS switching bandwidth service requests. It uses the SOAP protocol interface response to increase the ease of use of the system. As long as the client supports the SOAP protocol, it can access the BPS after being authorized.

 The Broadband Policy Server is a RADIUS client or proxy that is responsible for further service policy checking after RADIUS authentication is completed, providing online (dynamic) service policy checking, online session information maintenance and query, and online traffic switching time quota management, and A RADIUS server and an adapter of the BAS device (Broadband Access Server) can adapt the packet attributes of the RADIUS server and the BAS device of different vendors to link them.

 The Broadband Policy Multiservice Management Module is responsible for managing the services and the various policies and BPS configurations.

 The Broadband Policy Web Page (WEB) server is a client server that comes with the BPS system. It is responsible for providing users with online bandwidth service switching and is responsible for interacting with network users.

 Of course, the BPS system can also not have its own WEB server, and the WEB server can be externally connected. Here, the BPS system access is all controlled by the broadband policy gateway. As long as the client uses the SOAP protocol to send the correct SOAP request to the broadband policy gateway through the IP address, the broadband policy gateway can respond.

 For example, the user enters the correct WEB server address through IE, opens the page and enters the previously registered user name and password to send a command to change the bandwidth through the WEB server to the broadband policy gateway. The access in this way is called B/S ( Browser/Server) framework. Another way is that the user can install a special software. After double-clicking the software, you can enter the change bandwidth service interface. This access method is called C/S (Client/Server) framework.

 The database in the BPS system stores all the information of the BPS system, for example, including the following information:

 The broadband policy gateway stores user information that can log in to the BPS system in the database, for example, a login account and a password;

The broadband policy multi-service management module stores the broadband service information required by the BPS system in the database, mainly including: all broadband package combinations, such as the cost of the 1M package, the cost of the 2M package; BPS The broadband package corresponding to the network users registered in the system (normally used by default), the value-added broadband package that each user can enjoy (ie, the bandwidth that can be upgraded);

 The Broadband Policy Server stores all online information of online users and the currently used broadband attributes in the database, such as online duration, bandwidth, and so on.

In order to help the user to conveniently use and assist the operator to operate conveniently, the system of the present invention innovates two modules, and exerts compatibility and adaptability of the system.

 For the user, the system provides the above-mentioned module called the broadband policy gateway, and uses the SOAP protocol as the switching bandwidth service request entry of the system, which increases the ease of use of the system, as long as the client supporting the SOAP protocol is authorized. All can access the system. The authentication method of the system and the user's access network (which can be authenticated by webpage or authenticated by the client) is irrelevant. The terminal that can be used is not only a PC, a smartphone, but also other mobile devices.

 For the operator, the system provides the above-mentioned module called the broadband policy server, as a

The adapters of the RADIUS server and the BAS device can be used to match the packet attributes of the RADIUS server and the BAS device of different vendors. For example, the current situation is that the carrier can only use the BAS device of the A vendor to use the RADIUS of the A vendor. The BAS of the B vendor cannot be associated with the RADIUS of the A vendor. With the system, after the attribute configuration conversion (encoding implementation) of the broadband policy server, the operator can use the RADIUS of the A vendor and the BAS of the B vendor (or vice versa), and increase the operator's choice of the device. Right, reducing the operating costs of operators.

2 is a flowchart of a method for dynamically adjusting a bandwidth service according to the present invention. As shown in FIG. 2, the following steps are included:

 Step 10: The BPS captures the login information of the user accessing the network, and constructs the online information of the user. Step 20: After receiving the request for the user to initiate the handover bandwidth service, the BPS sends a service switching request carrying the information about the bandwidth to be switched by the user to the bearer layer.

Step 30: If the BPS receives the original bandwidth service accounting message initiated by the bearer layer and starts the new bandwidth service accounting message, the BPDU is processed and then forwarded to the application layer to release the original bandwidth service resource. Open a new bandwidth service resource.

 In this way, according to the method for dynamically adjusting the bandwidth service, the user can customize and control the network bandwidth required by the user, and meet the personalized requirements of the user and reduce the user cost, and also improve the effective utilization of the network resource; And when the bandwidth is changed, the user keeps the line and the user experience is guaranteed.

FIG. 3 is a flowchart of a method for dynamically adjusting a bandwidth service according to the present invention. As shown in FIG. 3, the method includes the following steps:

 110. The user accesses the IP through the network, correctly logs into the Internet, and can access the network;

 120. The BPS captures login information of the user accessing the network, and constructs online information of the user.

130. The user initiates a handover bandwidth service request.

 For example, the user can log in to the self-service page provided by the BPS. The self-service page has the function of switching the network bandwidth service online, selecting the bandwidth service to be switched and the duration of the handover.

 140. After receiving the request, the BPS notifies the BAS device to switch the bandwidth service.

 Specifically, the BPS can carry QoS through the COA command of the RADIUS protocol (Quality of

Service, Quality of Service), ACL (Access Control Lists), new bandwidth service ID, session timeout time and type information of the new bandwidth service ID, and notify the BAS device to switch services.

 150. After receiving the notification, the BAS device determines whether the service can be switched. If not, the switch fails to return, and the step ends. If possible, the BAS device uses the authorization attribute in the COA instruction as the user authorization attribute under the new service ID.

 160. The BAS device initiates the original service accounting termination message to the BPS, and the BPS releases the resources of the original service, and forwards the original service accounting termination message to the RADIUS server.

 170. The BAS device initiates a new service accounting start message to the BPS, and the BPS starts the resources of the new service, and forwards the start message of the new service accounting to the RADIUS server.

 This enables dynamic adjustment of bandwidth services.

Further, 180, BPS compares the current bandwidth service information of the user account with the request for switching If the bandwidth service information is consistent, the handover bandwidth service success message is returned to the client; if not, the handover bandwidth service failure message is returned to the client.

 If the user wants to switch back to the original bandwidth service, select the switchback service on the self-service page provided by the BPS, and then return to step 130.

 The execution order of the BPS support step 160 and the step 170 is reversed, so that the user can smoothly switch the network bandwidth service without guaranteeing the line, and ensure the continuity and correctness of the billing.

An application example of the method for dynamically adjusting bandwidth services of the present invention is described in detail below. In the application example, the webpage provided by the broadband policy WEB server 104 is used as a client for interacting with the user.

 First, the broadband policy multi-service management module 103 establishes a corresponding account for accessing the network authentication, and a conventional network bandwidth service that can be used by the account (the conventional network bandwidth service has one and only one, such as 1M bandwidth, user The bandwidth that is not used for bandwidth switching operations when logging in to the network) and the network bandwidth value-added services that can be switched (multiple, for example, configurable 2M bandwidth, 4M bandwidth, as switchable temporary bandwidth), and configured for these services Broadband strategy.

 The user accesses the network in any way, but the user performs the online authentication. When the BAS device performs AAA authentication on the RADIUS server, the BAS device sends the packet to the BPS broadband policy server 102. The broadband policy server 102 reassembles the RADIUS protocol packet. Send it to the destination RADIUS server for AAA authentication. In this way, the broadband policy server 102 can capture the user login information at the time of accounting, and constructs the online information of the user itself to provide bandwidth switching.

 After the user successfully logs into the Internet (the broadband policy server 102 captures the user login information at the time of accounting, and constructs the online information of the user itself), the online information self-service page provided by the broadband policy WEB server 104 is opened, and the self-service page indicates that the user is working. The regular bandwidth service is used, and a list of value-added services that can switch bandwidth is provided for the user to select. After the user performs the service switching operation on the page, as shown in Figure 4, perform the following steps:

Step 201: The broadband policy WEB server 104 initiates a service switching request to the broadband policy gateway 101 through a SOAP (Simple Object Access Protocol) interface. Step 202: The broadband policy gateway 101 sends the service switching request to the broadband policy server 102 through a UDP (User Datagram Protocol) private port after responding to the request.

 Step 203: After responding to the request, the broadband policy server 102 carries information such as QoS, ACL (Access Control Lists, access control list), new broadband service ID, and session timeout and type of the new broadband service ID through the COA command. Inform the BAS device to switch services.

 Step 204: The BAS device determines whether the regular bandwidth service ID and the value-added bandwidth service ID to be switched are the same. If they are the same, no processing is performed; if different, and the switching service condition is met, then the process proceeds to step 205.

 Further, the BAS device compares the IDs of the two bandwidth services. If the IDs are inconsistent, the database query is used to confirm whether the user account has the right to switch to the "value-added bandwidth service ID to be switched", and the account balance of the user is queried through the database. Whether it can support the service usage time after switching, etc. If the above conditions are not met, the handover failure message is returned, and the step ends; if the above conditions are met, the service scenario that the user requests to switch is entered (indicating that the user can use the handover) Bandwidth), the BAS device uses the authorization attribute in the COA instruction to act as the user authorization attribute under the new service ID, that is, re-arrange the usage of the bandwidth according to a series of attributes under the new service ID.

 Step 205: The BAS device initiates a billing stop message of the original regular service ID to the broadband policy server 102.

 Step 206: The broadband policy server 102 converts the accounting stop message of the original service into a RADIUS protocol format that the RADIUS server can recognize, and then forwards the packet to the RADIUS server.

 Step 207: The broadband policy server 102 releases the resources on which the original service is located, stops the original service accounting, and notifies the RADIUS server.

 Step 208: The RADIUS server returns the original service accounting stop response to the broadband policy server 102.

 Step 209: The broadband policy server 102 returns the original service accounting stop response to the BAS device. Step 210: The BAS device initiates the accounting of the added value service ID to the broadband policy server 102.

Step 211: The broadband policy server 102 converts the accounting start message of the new service into the The RADIUS protocol format recognized by the RADIUS server is forwarded to the RADIUS server. Step 212, the broadband policy server 102 starts new service accounting, and notifies the RADIUS service to cry.

 Step 213: The RADIUS server returns a new service accounting start response to the broadband policy server 102.

 Step 214: The broadband policy server 102 returns a new service accounting start response to the BAS device. Step 215: The broadband policy server 102 returns a service switching response to the broadband policy gateway 101. Step 216: The broadband policy gateway 101 returns a service switching response to the broadband policy WEB server 104 through the SOAP interface.

 In step 205 and step 210, the broadband policy server 102 converts the accounting start of the original regular service ID and the start of the accounting of the added value service ID (in no particular order) after receiving the BAS, respectively, and converts them into RADIUS. The protocol format is forwarded to the RADIUS server, and the broadband policy server 102 manages the value-added service information portion of the user's online information (including its life cycle). After the bandwidth is dynamically increased, the user usage information is tracked for background charging. When the cumulative time quota is full, the pre-upgrade service policy is automatically restored according to the previously set policy or directly offline. Since the broadband policy server 102 itself maintains the user online information, including the regular service information and the value-added service information, the regular service information resource and the value-added service information resource can be separately managed, so that the user can keep the online while switching the bandwidth service.

 Step 217: The broadband policy WEB server 104 sends a request for the current broadband service information of the user account after the handover to the broadband policy gateway 101 through the SOAP protocol interface.

 Current broadband service information can include: QoS, ACL, new broadband service ID, session timeout and type of new broadband service ID, and so on.

 Step 218: The broadband policy gateway 101 sends the request to the broadband policy server 102 through the UDP private port after responding to the request.

 Step 219 - Step 220: The broadband policy server 102 retrieves the current broadband service information, and returns the broadband service information of the current bandwidth name, current usage time, remaining usage time, and the like to the broadband policy WEB server 104 through the broadband policy gateway 101.

Step 221: The broadband policy WEB server 104 compares the ID of the broadband service, and determines the returned Whether the ID of the broadband service in the information is the same as the broadband service ID requesting the handover, if it is consistent, the handover success is displayed on the self-service page; if not, the handover failure is displayed.

The above is only a preferred embodiment of the present invention, and of course, the present invention may be embodied in various other embodiments without departing from the spirit and scope of the invention.
