System and method for communications with reservation of network resources, and terminal therefore

摘要

The communication system supports reservation of network resources. The base stations (1), (2) and (3) relay packets among the terminals (10), (20), (30), and (40), and perform priority control based on the priority set to the packets. In the terminal (10), the communication-managing table (13) stores communication information of own terminal and a partner thereof. The packet-transmitting unit (11), setting priority to the packets, transmits the packets. When link condition of own terminal change, the link-managing unit (14) updates, in order to prevent from quality deterioration of the other terminals, the priority of each of the packets whose source terminal is the own terminal.
