Abstract:
In a Ubiquitous Consumer Wireless World (UCWW) environment
the provision, administration and management of the authentication, authorization
and accounting (AAA) policies and business services are provided by third-party
AAA service providers (3P-AAA-SPs) who are independent of the wireless access
network providers (ANPs). In this environment the consumer can freely choose any
suitable ANP, based on his/her own preferences. This new AAA infrastructural
arrangement necessitates assessing the impact and re-thinking the design,
structure and location of ‘charging and billing’ (C&B) functions and services. This
paper addresses C&B issues in UCWW, proposing potential architectural solutions
for C&B realization. Implementation approaches of these novel solutions together
with a software testbed for validation and performance evaluation are addressed.
