A heterogeneous wireless communication system and a method of operation thereof

摘要

A heterogeneous wireless communication system supports reconfigurable user terminals. A user authentication server (107) of a visited communication network (105) for a user terminal (101) performs user authentication of a user of the user terminal (101) in response to user authentication information received from an authentication server (111) of the user terminal's home communication network. The user terminal (101) receives reconfiguration information for the visited communication network and requests reconfiguration data from the visited communication network. A terminal authentication server (117) performs terminal authentication of the user terminal (101). The terminal authentication server (117) is a common terminal authentication server for a plurality of communication networks including the visited and home communication network. A reconfiguration server (109) of the visited communication network (105) then provides user terminal reconfiguration data to the user terminal (101) conditional on the user authentication and the terminal authentication of the user terminal (101).
