摘要:
Disclosed is a communication system in which appropriate retransmission control operations are respectively performed for two data types including real time data and non real time data, and the transmitter and the receiver used for this communication system. A data type identifier (240) identifies a data type as real time or non real time, and based on the identified data type, a controller (210) and another controller adjust parameters used for retransmission control.

In amobile communication system 1 having a radio base station 2, and mobile stations 5, 6 configured to communicate with the base station 2 and segmented into a plurality of mobile station groups, the base station 5 provides a broadcast channel with first instruction information to notify the mobile station 5 of whether or not to receive the broadcast channel, provides a paging channel with second instruction information to notify the mobile station 5 of the presence/absence of paging information, and performs such a channel transmission control as to intermittently transmit the broadcast channel and the paging channel on a control channel.

摘要:
A communication system (100) includes a relay apparatus (AP) which offers an access link to a mobile terminal, a layer 2 switch (3) which relays data between the relay apparatus and a router on a next hop from a communication destination terminal of the mobile terminal (MN) and a route information notification unit. The route information notification unit notifies to the relay apparatus (AP) and the layer 2 switch (3) in a subnet where the mobile terminal (MN) is present, route information including a data link layer unicast address of a packet addressed to the mobile terminal (MN), and a data link layer multicast address thereof in a case where the mobile terminal (MN) is activated and in a case where the mobile terminal (MN) switches a connection.
