COMMUNICATION SYSTEM AND DEVICE

摘要

A communication system (500) comprising a plurality of devices (101-106) interconnected via a bus, the bus being capable of handling isochronous and asynchronous transmissions. A status manager (105) periodically broadcasts status information on the bus in asynchronous transmissions. Devices (101-106) can send status information to the status manager (105) so it can broadcast it over the bus. Information is sent at a reduced frequency, which saves bandwidth. This information can be about the network topology of the communication system (500), about capabilities of a device (101-106) in the communication system (500), about available bandwidth on the bus, or about the strength of a level of attachment between a mobile device (520) and a base station device (106) in the communication system (500). In a preferred embodiment, the status information is embedded in the Cycle Start (CS) packet.
