Communication control system and method of controlling communication
First Claim
1. A communication control system in a packet communication network having a plurality of radio sub-networks, said radio sub-networks being connected to a wired sub-network by learning type bridges, respectively, said system comprising:
- a radio terminal for communicating with said radio sub-networks, said radio terminal including;
first means for detecting whether or not said radio terminal moves from one of said radio sub-networks to other radio sub-networks; and
second means for transmitting a dummy packet when movement between said radio sub-networks is detected.

11. A method of controlling communication in a packet communication network having a plurality of radio sub-networks, said radio sub-networks being connected to a wired sub-network by learning type bridges, respectively, said packet communication network comprising a radio terminal for communicating with said radio sub-networks, said method comprising steps of:
-
detecting whether or not said radio terminal moves from one of said radio sub-networks to other radio sub-networks; and
transmitting a dummy packet when movement of said radio terminal between said radio sub-networks is detected. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
