A novel architecture for future integrated wireless network is proposed in MIRAI (Multimedia Integrated network by Radio Access Innovation) where a dedicated network takes care of the mobility functionalities of the participant wireless networks in the integration. The dedicated network, called basic access network (BAN) is used for paging whenever a call arrives for the mobile user for any of the wireless interfaces of the user's multiservice terminal. We analyze a scheme for using the BAN channel, and associated network to aid the AAA (authentication, authorization and accounting) and IP mobility functionalities of the integrated network environment in a seamless fashion.
