Abstract
Call connection processing is performed and a message is processed in a different subnet without UATI reassignment and takeover of a wireless session. RANs that belong to different subnets and are adjacent to each other use messages to exchange ColorCode, IP addresses of base station controllers, wireless resource information of base station transceiver subsystems and the like. When the RAN receives, from an AT, a message having ColorCode that is different from ColorCode of the RAN, the RAN transfers the message to a base station controller included in the RAN having ColorCode that matches the ColorCode included in the message.
