Selecting base stations dependent upon traffic types and end to end quality of service of network path via base-station

摘要

The invention is claimed broadly as selecting any intermediate device based upon the quality of service between two end points via that device. The embodiments specifically relate to selecting base stations A-F based upon the quality of service provided between communications control unit (CCU) 2 and a home agent 4. The CCU is preferably a hub on a vehicle (eg. train 1) providing internet access to passengers using an on-board local area network (LAN). Traffic may be assigned to classes with different quality requirements (see Fig. 4). The quality requirement may relate to latency or tolerance of disruption. Traffic may compete for bandwidth on a particular base station (See Figs. 3a,3b).
