DOMESTIC COMMUNICATION AND ENTERTAINMENT SYSTEM

摘要

In a domestic communication and entertainment system (1), a plurality of devices (2-10) are interconnected by a databus (11). A first one of the devices receives a demand for a task requiring a communication session with an entity external to the system and the device transmits to a routing device (12) connected to the databus a request message for routing information which defines a preferred route for initiating the communication session. The routing device accesses a lookup table to obtain the information and transmits a response message comprising the routing information to enable the device to initiate the communication session via a preferred route. The lookup table is updated by wireless transmission from a control centre. The system is enable to make optimum use of multiple communication systems available in the domestic environment by reference to routing information which can be configured to take advantage of network usage and other factors such as cost and availability.
