Abstract
A conventional nodedivides an IP packet into data fragments and prepares a packet for RANtransmission. There has been a problem that, since a RANcannot identify an IP packet unit, affinity is low relative to an IP networkthat serves as a core. A nodeprepares A10 packets by dividing an IP packet, and adds, to each A10 packet, a concatenation flag that indicates information stored in the A10 packet is the head or the tail of the IP packet. A base stationand a packet control deviceemploy the concatenation flag to control transmission for each IP packet unit. For example, a packet control deviceemploys a concatenation flag to discard information for a series of A10 packets received by the node, including information that constitutes the same IP packet.
