<P>PROBLEM TO BE SOLVED: To solve the problem that a state called congestion to make communication impossible occurs, which easily causes congestion in communication of a line switching method such as voice communication in particular since many users make telephone calls for urgent contact or secure safety concurrently in a disaster such as an earthquake, bringing about communication demands that exceed line capacity. <P>SOLUTION: A base station always monitors by an acceleration sensor whether shaking occurs. When the base station observes big shaking, the base station autonomously performs congestion avoidance communication control without waiting for control from a high order communication network. The base station autonomously performs control to release a band connection mode, and performs communication control to give priority to communication with a small amount of capacity for a large number of people (priority over securement of the number of lines) from communication with a large amount of capacity for a small number of people. <P>COPYRIGHT: (C)2008,JPO&INPIT |
