<p>In a network composed of mobile nodes conforming to the edge mobility, access gateways, and position managing devices, the position managing devices are distributed, and uplink/downlink deliveries of transmission/reception packets transmitted/received between mobile nodes are performed through a single path. A mobile node (1) is registered in a belongingness list of a position information management table of an MAG(1) (7), and an LMA(2) (17) is registered in a mobile node (2) (11). In the mobile node (1) (1) of the position information management table of an MAG(2) (11), an LMA(2) (17) is recorded; and in the mobile node(2) (3), belongingness is recorded. Thus, when communication between mobile nodes is started, the access gateway to which each mobile node belongs uniquely determines a position management device for transferring a packet thereby to determine a single path. With this, in a network composed of mobile nodes conforming to the edge mobility, access gateways, and position management devices, the difference in arrival time between the uplink path and the downlink path of communication between mobile nodes is eliminated, and degradation of the communication quality is prevented.</p> |
