摘要

System and method for use of internet authentication technology to provide UMTS authentication. An SGSN 260 in an Integrated Network Contoroller 240, in a UMTS network and a RADIUS server 270 are adapted to support signalling therebetween whereby authentication of a USIM is performed in the RADIUS Server. This allows a conventional Authorisation Centre (AuC) to be replaced by the RADIUS Server, and it is substantially cheaper, because it is based largely on existing off-the-shelf Internet access authentication technology, modified to this purpose.
