Method and apparatus enabling reauthentication in a cellular communication system

摘要: A method (and corresponding equipment) for us in reauthentication--after a first, full authentication by first server (23a)--of communication session involving the exchange of information between terminal (21) and (24), including: step (11) which (23a) other servers (23b) are each assigned respective unique realm name; (13) during (23a), transmits to reauthentication identity including name server. Then, later, reauthentication, make possible that is performed same as authentication--i.e. (23a)--the included request reauthentication.
