Hybrid base station transceiver with protocol matching units for connecting a wireless terminal to different communication networks based on a signal received from the terminal, and corresponding method and communication system

A hybrid base station transceiver (300) has an ATM matching unit (310) for connecting a wireless terminal to an ATM-based communication network, in particular for connecting to an ATM-base station controller (110); an IP matching unit (330) for connecting a wireless terminal to an IP-based communication network, in particular for connecting to an IP-base station controller (210); a channel and RF processor (340) for performing physical connection protocol processing and RF transceiving processing with the wireless terminal; and a routing processor (320) for determining which network to which the wireless terminal is to connect to by analyzing a signal of OSI Layer 2 or Layer 3 received from the wireless terminal and for connecting the wireless terminal to the ATM-based or IP-based communication network through the channel and RF processor according to the analysis.
