This paper proposes a 4G 'Generic ANWIRE system and service Integration Architecture' (GAIA). The relationship between the different GAIA domains is explained and interaction between their functional entities is shown in order to explore various GAIA properties. An overview of the relevant topics related to the GAIA architecture and its respective elements is given. A well-based summary on system integration efforts of previous projects is provided as a basis for deriving of various requirements for GAIA. New two-phase business model to accommodate the 4G development is proposed and justified. Finally, a new reference communication model of a future 4G wireless system is proposed and GAIA interdomain signalling issues are discussed.

Robert Kirberger and Fintan McEvoy, editors of the forthcoming new edition of the BSAVA Manual of Canine and Feline Musculoskeletal Imaging, introduce Companion readers to this fascinating field.

This paper proposes a new third-party AAA (3P-AAA) supporting architecture, with which to serve a more consumer-based business model (CBM) for fourth generation wireless world (4GWW). A new diameter 3P-AAA application is suggested as a base signaling protocol solution option to serve this architecture. The command and response messages necessary for this application are identified and elaborated

The consumer-based techno-business model (CBM) serves as a basis for the new emerging ubiquitous consumer wireless world (UCWW). For it all authentication, authorization and accounting (AAA) is handled by third-party AAA service providers (3P-AAA SPs). A possible architecture, a candidate signalling protocol and a functional model for 3P-AAA are considered in this paper. A testbed proposal for 3P-AAA, which contains embedded new security features, is set out. The approach towards simulation and development of this testbed so as to create a 3P-AAA prototype system is elaborated
