Abstract:
1. A network apparatus for ubiquitous computing comprising: a movement detection unit which detects movement from a first network to a second network; a movement address setting unit which generates care-of-address (CoA) information corresponding to prefix information of the second network; a movement registration unit which registers a movement address by transmitting a binding update message containing the generated CoA and home address (HoA) mapping information, to a home agent; a resource setting unit which registers information on current terminal apparatuses among network terminal apparatuses on the second network through ubiquitous registration solicitation of ubiquitous router advertisement; and a packet distribution unit which distributes the received packet to a current terminal apparatus corresponding to the application characteristic of the packet received from the home agent based on the information on the current terminal apparatuses, wherein after said resource setting unit completes registration of the information on current terminal apparatus, requests said information, the resource setting unit informs the packet distribution unit of a list of the current terminal apparatus through ubiquitous registration indication messages.
