A 4G generic ANWIRE system and service integration architecture

Abstract

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.
