Abstract:
1. A mobile terminal, comprising: a plurality of radio communication interfaces; a mobile IP module to fulfill a mobile IP function; and a protocol switch module configured to transmit identification information to identify a binding update message transmitted from a first radio communication interface among said plurality of radio communication interfaces or to identify a binding update message to be transmitted from said first radio communication interface among said plurality of radio communication interfaces, wherein the protocol switch module transmits said identification information from a second radio communication interface connected to a home domain where a network-based local mobility management protocol is provided among said plurality of radio communication interfaces; wherein the protocol switch module transmits a request to a network node where said second radio communication interface is connected, to notify a packet transfer management node in said home domain by adding current time information to said identification information; wherein said identification information is transmitted from said second radio communication interface when said first radio communication interface changes connection destination from said home domain to another domain and has transmitted or is going to transmit said binding update message from said first radio communication interface.
