Abstract
The present invention provides a method for network service selection and authentication in an IPv6 access network, a scheme for stateless auto-configuration and devices thereof. A NSP Information option containing the IPv6 address of a NSP edge router and a NSP name is defined in RA messages. A NSSA Information option is defined in RS option fields. The present invention enables IPv6 stateless auto-configuration in an access network. The new NSP Information option, the way of “one time authentication per subscriber network per NSP” and the use of IPv6 routing header promote the efficiency of IPv6 stateless auto-configuration and reduce the NSP selection and authentication traffic. The present invention provides an efficient solution for network service selection and authentication without introducing any other message exchange between terminals and access nodes. In short, the scheme of network service selection and authentication according to the present invention is piggybacked on RS/RA messages, which is very simple.
