In this thesis we study and evaluate the exchange of signals required in
Third-Generation Mobile Networks, UMTS. In UMTS, authentication functions are
utilized to identify and authenticate a mobile station (MS) and validate the
service request type to ensure that the user ia authorised to use the
particular network sevices. The authenticating parties are the Authentication
Center (AuC) and the MS. In UMTS, the Serving General packet radio service
Support Node (SGSN) accesses the AuC to obtain the authenticating data, and
delegates the AuC to perform mutual authentication with the MS. Since the cost
for accessing AuC is expensive, the SGSN may obtain an array of elements, which
are called Authentication Vectors (AVs), at a time so that the number of
accesses can be reduced. According to the size of the array cost for accessing
AuC may be small or big. In addition, there are some other parameters of the
network which influence the cost, such as the sending packet rate from SGSN to
MS, the sending rate for call request from MS to SGSN and from SGSN to HLR/AuC,
the time duration until the next call request and the time duration until the
MS leaves the area of an SGSN.
