[0035] Such as Figure 4 As shown, in step 402, the broadband access control platform receives a policy service request, the policy service request including at least the type and parameter information of the policy service.

[0036] In step 404, the broadband access control platform converts the parameter information in the policy service request into a corresponding dynamic policy of the dynamic policy execution device interface protocol, and sends the converted service dynamic to the dynamic policy execution device through the dynamic policy control interface Strategy.

[0037] In step 406, the dynamic policy execution device executes the service dynamic policy.

[0038] Figure 5 It is a flowchart of another embodiment of the broadband access dynamic policy control method of the present invention.

[0039] Such as Figure 5 As shown, the control method of the system includes the following steps:

[0040] In step 502, the user applies for a policy service to the broadband access control platform through the client software applied for the dynamic policy service (or the application that accesses the SP through the SP interface of the dynamic policy service), and the SP request includes at least the service code/platform of the SP Code, authentication password, user information (such as user account information, user IP address, etc.), policy service type code, policy service parameters, etc.

[0041] In step 504, the broadband access control platform verifies the legitimacy of the application platform (or SP), establishes a trust relationship if it is legitimate, and receives a policy service request.

[0042] In step 506, the broadband access control platform determines the BRAS/SR or home control terminal to which the user belongs according to the user's IP address or account information, and then checks whether the network resources required by the policy service type and parameters can be met, and if the resources are not met, it is rejected The policy service request, if the resource is satisfied, is converted into the corresponding dynamic policy enforcement device (DPED) interface protocol according to the parameter information of the policy service.

[0043] In step 508, the broadband access control platform returns the request result to the application platform (or SP) and distributes the authentication token.

[0044] In step 510, the broadband access control platform issues to the dynamic policy execution device for execution.

[0045] In step 512, the broadband access control platform directly (or indirectly through the terminal remote management system) sends the dynamic policy or control information to the user access control signaling conversion device (CSSD) according to the needs of the dynamic policy.

[0046] In step 514, the client software (or SP application) of the dynamic policy service application maintains timing heartbeat information with the access control platform. The heartbeat information includes at least parameters such as policy service type and authentication token.

[0047] Image 6 A schematic diagram showing a dynamic example of the broadband access dynamic policy control system of the present invention. It consists of broadband access control platform (including home gateway management system 601) 201, service gateway BRAS/SR (DPED) (204), home gateway (603)/home control terminal (605) (CSSD) and client (202) four Partial composition. The home gateway management system 601 issues dynamic policies or control information to the home gateway 603 through the TR069/SNMP protocol. The access dynamic strategy control system directly or through the terminal remote management system issues service priority marks to the home access/control terminals.

[0048] In the following, the dynamic bandwidth guarantee application and the broadband VoIP (Voice over IP, IP phone) application triggered by the phone are taken as examples to illustrate the entire process.

[0049] Figure 7 It shows a schematic diagram of the dynamic bandwidth guarantee control process of the present invention.

[0050] Such as Figure 7 As shown, the dynamic bandwidth guarantee control process includes steps:

[0051] In step 702, the user submits a dynamic bandwidth guarantee service request to a CP (Content Provider, content provider).

[0052] In step 704, the CP sends a CP identity authentication request to the broadband access control platform, and the request includes at least the CP's service code and authentication password.

[0053] In step 706, the broadband access control platform performs identity authentication on the CP.

[0054] In step 708, the authentication is passed, the authentication result includes the token passed the authentication, and the broadband access control platform establishes a trust relationship with the CP.

[0055] In step 710, after CP identity authentication, a service request is made to the broadband access control platform. The service request includes at least the CP token, service type, and service parameters (such as online application type, bandwidth, duration, etc.).

[0056] In step 712, the broadband access control platform determines whether the service application can be satisfied according to the resource status of the BRAS/SR and the requested service parameters.

[0057] In step 714, the broadband access control platform returns the service request result to the CP.

[0058] In step 716, if the resource meets the service request, the broadband access control platform dynamically issues a bandwidth control strategy to the BRAS/SR. The strategy includes at least information such as bandwidth size and service level category.

[0059] In step 718, if the resource meets the service request, the broadband access control platform directly or through the terminal remote management system issues a service priority mark and a bandwidth guarantee policy to the home terminal. The strategy includes at least: bandwidth size, service type (such as quintuple), service priority and other information.

[0060] In step 720, the CP and the broadband access control platform maintain timing heartbeat information. The heartbeat information includes at least parameters such as policy service type and authentication token.

[0061] Picture 8 It shows a schematic diagram of the control flow of the broadband VoIP remotely triggered by the telephone.

[0062] In this embodiment, the PSTN is used as the control signaling channel of the broadband VoIP application, and the broadband access channel is activated through the control signaling as the signaling and data channel of the broadband application.

[0063] Such as Picture 8 As shown, in step 802, an ordinary telephone user directly (or through a specific access number) calls another VoIP user number;

[0064] In step 804, the softswitch verifies the rights of the calling user, and then finds whether the called VoIP user has registered with the softswitch (that is, whether it is online), and if it has already registered with the softswitch, the normal call flow is processed.

[0065] In step 806, if it is not registered with the softswitch, a request to call an unregistered user is initiated to the broadband access control platform.

[0066] In step 808, the broadband access control platform selects the appropriate call center number as the caller according to the softswitch service request code, and starts calling the user's home control terminal (the terminal has a traditional PSTN telephone line); the broadband access control platform can also Trigger the home control terminal through the terminal remote management channel.

[0067] In step 810, the home control terminal judges the operation instruction according to the calling number decoding result of the call center (different calling numbers in the call center correspond to different business operations of the home control terminal, such as: a certain calling number corresponds to voice calls, video calls, and Turn on/off the power switch of the application, etc.).

[0068] In step 812, the home control terminal starts the power supply of the VoIP terminal.

[0069] In step 814, the VoIP terminal starts broadband access and registers with the softswitch.

[0070] In step 816, the softswitch starts to call the called user according to the normal call flow.

[0071] In step 818, the communicating parties start talking.

[0072] The broadband access dynamic strategy control system and method of the present invention, by providing a unified network device control interface or an adaptation layer control interface, realizes the control capability across networks (such as PSTN/softswitch/broadband network); provides users/ISPs Unified service trigger entry and open application layer interface; CCSD equipment has the conversion function of PSTN/softswitch network and broadband network control signaling, and can provide characteristic broadband video surveillance and VoIP telephone services. The system supports smooth expansion; for example, a dynamic network policy control interface adapted to network devices can support smooth expansion of the system to support more devices; providing a unified dynamic service strategy trigger interface for SP applications can support the smooth introduction of more SPs in the system Applications call services based on dynamic network policy control capabilities; the broadband access control platform adopts the J2EE service framework to support the expansion of system capacity by increasing the number of hardware servers.

[0073] The broadband access dynamic strategy control system and the control method thereof of the present invention are a solution with good effect and reasonable deployment cost for solving current access control and service quality problems. Through the interactive control between the dynamic policy control platform, BRAS/SR equipment, and access/application terminals, the network capability of the access network is closely integrated with the operator's business, so as to realize the operator's precise management and control of network resources and business processes It also provides users with differentiated services, security-guaranteed services and some special applications, and finally realizes that the consumption of business traffic is proportional to the relationship between business income and obtains due benefits from applications and content.
