IP-BASED WIRELESS ACCESS NETWORK, CORRESPONDING BASE STATION, AND ADDRESS DESIGNATION SCHEME USED BY WIRELESS NETWORK CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide an address designation scheme where data for a wireless terminal needs no other signal plane for signaling a type of a wireless channel to be transported on a wireless interface. SOLUTION: In the address designation scheme of this invention, a type of a wireless channel used by a base station for communication with an end user wireless terminal is switched over via a wireless access network and is decided by a port number denoted in a data packet with each TCP(transmission control protocol) or each UDP(user datagram protocol) belonging to the communication with the end user wireless terminal in a unified way.
