ITU-T Recommendation Q.3201 describes the security signalling requirements and protocol architecture for supporting access security aspects of network attachment procedure in a next generation network (NGN). Basic threats and security requirements for the attachment of NGN access networks are analysed, and a model of an extensible authentication protocol (EAP)-based security signalling protocol architecture accommodating heterogeneous multi-links in the next generation network access environment is presented. Based on it, three feasible scenarios for authentication signalling in NGN network attachment control functions are developed.
