Embodiment Construction

[0034] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0035] The present invention aims to provide a method and system for negotiating security policies in NGN. By extending the existing NGN architecture, adding security policy-related network elements and standardizing security policy negotiation and execution procedures, so as to meet the requirements of security policy management in NGN need.

[0036] A security policy management framework in the NGN domain provided by the embodiment of the present invention, such as figure 2 As shown, a Security Policy Server (SPS, Security Policy System) and a Security Policy Enforcement Point (PEP, Policy Enforcement Point) are added to the transmission plane of the existing NGN architecture to implement decision-making and execution of security policies. SPS is mainly used to store and distribute security policies, and PEP is u...

Abstract

The invention discloses a consultation method and system for a security policy in a next generation network (NGN). The method comprises the following steps: after a security policy enforcement point (PEP) receives a connection request message initiated by user equipment (UE) in the affiliated NGN, sending a policy query request message to a security policy server (SPS) in the affiliated NGN to request to query a security policy relevant to the policy query request message; and returning the queried security policy back to the PEP for performing by the SPS via policy query response. According to the consultation method and system for the security policy in the NGN, the requirement of managing the security policy in the NGN is satisfied.

Description

technical field [0001] The invention relates to the field of communication security, in particular to a method and system for negotiating a security policy in a next generation network (NGN, Next Generation Network). Background technique [0002] As more and more operators are developing towards the full service direction, NGN is also developing towards the direction of integration. Existing NGN architecture such as figure 1 As shown, the service plane includes application / service support function modules, service control and content distribution function modules, and the transmission plane includes network attachment control function modules, mobility management control function modules, and resource admission control functions (RACF, Resource and Admission Control Functions) module, transmission function module; the management function module, identity management module (IDM, Identity Management) function module, end user function module, other service provider function m...
