Abstract

The disclosure provides a method for resource and admission control of a home network, the RACF of an NGN retail service provider formulates an initial policy rule according to a resource request after receiving the resource request sent by an SCF; a CPN performs authorization check on one or more resource requests after receiving them, each of which includes the initial policy rule and is sent by an RACF of a respective NGN retail service provider, formulates a final policy rule after the authorization check is passed, and executes the final policy rule. The disclosure further provides a system for resource and admission control of a home network correspondingly, since a CGPE-FE executes corresponding operation according to the decision result of an HPD-FE, the disclosure can avoid resource control errors such as resource desynchrony or resource inconsistence, and can improve system stability.

Claims

1. A method for resource and admission control of a home network, comprising:

performing authorization check, by a Resource and Admission Control Function (RACF) of a Next Generation Network (NGN) retail service provider, on a resource request after receiving the resource request sent by a Service Control Function (SCF), formulating an initial policy rule after the authorization check is passed, and sending a resource request comprising the initial policy rule to a Customer Premises Network (CPN);

performing, by the CPN, authorization check on one or more resource requests after receiving them, each of which comprises the initial policy rule and is sent by an RACF of a respective NGN retail service provider, formulating a final policy rule after the authorization check is passed, and executing the final policy rule;

wherein sending the resource request comprising the initial policy rule by the RACF of the NGN retail service provider to the CPN, is;

sending, by a Policy Decision Functional Entity of the RACF of the NGN retail service provider (PD-FE(R)), the resource request comprising the initial policy rule to a Home network Policy Decision Functional Entity (HPD-FE) of the CPN,

performing the authorization check on the resource requests, formulating the final policy rule after the authorization check is passed, and executing the final policy rule by the CPN, is;

performing, by the HPD-FE of the CPN, the authorization check on the resource requests, and formulating the final policy rule after the authorization check is passed;

sending, by the HPD-FE, the resource request comprising the final policy rule to a CPN Gateway Policy Enforcement Functional Entity (CGPF-FE); and

executing, by the CGPE-FE, the final policy rule sent by the HPD-FE according to the received resource request.

2. The method according to claim 1, further comprising:

after the CGPE-FE executes the final policy rule,

sending, by the CGPE-FE, a corresponding resource response to the HPD-FE;

sending, by the HPD-FE, a corresponding resource response to the PD-FE(R); and

sending, by the PD-FE(R), a corresponding resource response to the SCF.

3. The method according to claim 1, wherein the resource request is a resource initialization request or a resource modification request.

4. The method according to claim 3, wherein the resource initialization request sent by the SCF to the PD-FE(R) comprises at least one of media stream description and Quality of Service (QoS) parameters;

the resource modification request comprises at least one of media stream description and QoS parameters needing to be modified.

5. The method according to claim 1, wherein the resource request sent by the PD-FE(R) to the HPD-FE comprises at least a PD-FE(R) identifier and the initial policy rule.

6. The method according to claim 1, wherein performing the authorization check by the HPD-FE on the resource request is:

checking whether QoS resources related to the resource request is consistent with a local operator policy rule.

7. The method according to claim 1, wherein the HPD-FE formulates the final policy rule according to one or any combination of the following elements:

resource availability of the home network, service level agreement, and the initial policy rule.

15. The method according to claim 2, wherein the resource request is a resource initialization request or a resource modification request.

16. The method according to claim 15, wherein the resource initialization request sent by the SCF to the PD-FE(R) comprises at least one of media stream description and Quality of Service (QoS) parameters;

the resource modification request comprises at least one of media stream description and QoS parameters needing to be modified.

8. A method for resource and admission control of a home network, comprising:

sending, by a Service Control Function (SCF), a resource release request to a PD-FE(R) according to a release request from a user;

sending, by the PD-FE(R), a resource release request to a Home network Policy Decision Functional Entity (HPD-FE);

sending, by the HPD-FE, a resource release request to a CPN Gateway Policy Enforcement Functional Entity (CGPE-FE);

sending, by the CGPE-FE, a resource release response to the HPD-FE after releasing corresponding resources according to the resource release request from the HPD-FE;

sending, by the HPD-FE, a resource release response to the PD-FE(R); and

sending, by the PD-FE(R), a resource release response to the SCF.

9. The method according to claim 8, wherein the resource release request sent by the SCF to the PD-FE(R) comprises information on QoS resources needing to be released.

10. A system for resource and admission control of a home network, comprising:

a Service Control Function (SCF), one or more Resource and Admission Control Functions (RACFs) each belonging to a respective NGN retail service provider, and a Customer Premises Network (CPN);

wherein

the SCF is configured to send a resource request to an RACF of an NGN retail service provider according to a request from a user;

the RACF of the NGN retail service provider is configured to perform authorization check on the resource request from the SCF, formulate an initial policy rule after the authorization check is passed, and send a resource request comprising the initial policy rule to the CPN;

the CPN is configured to perform authorization check on one or more resource requests after receiving them, each of which is from an RACF of a respective NGN retail service provider, formulate a final policy rule after the authorization check is passed, and execute the final policy rule;

wherein the RACF of the NGN retail service provider comprises a Policy Decision Functional Entity (PD-FE(R)), the CPN comprises a Home network Policy Decision Functional Entity (HPD-FE) and a CPN Gateway Policy Enforcement Functional Entity (CGPF-FE), wherein

the PD-FE(R) is configured to perform authorization check on the received resource request, formulate an initial policy rule after the authorization check is passed, and send a resource request comprising the initial policy rule to the HPD-FE;

the HPD-FE is configured to perform authorization check on the resource request from the PD-FE(R), formulate the final policy rule after the authorization check is passed, and send a resource request including the final policy rule to the CGPF-FE;
