Title:
MOBILE COMMUNICATION SYSTEM, ROUTING DEVICE, COMMUNICATION CONTROL METHOD AND ROUTING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/090013
Kind Code:
A1
Abstract:
Disclosed is a mobile communication system (100) comprising a routing device (110) and a plurality of wireless base stations (130 and 140) of different data communication speeds. The routing device (110), when a wireless base station (130) of high data communication speed is relaying data between a mobile unit and the routing device (110), calculates the throughput of data transmitted and received by the mobile unit. If the throughput calculated within a pre-defined time is less than or equal to a pre-defined threshold, the routing device (110) determines that communication between the mobile unit and the routing device (110) should be relayed by a wireless base station (140) of low data communication speed, and controls switching of the wireless base station.
