Abstract
A method of broadcasting firmware updating messages in a communication system includes the steps of receiving a broadcast remote firmware update (BRFU) setup message from an upstream source, the BRFU setup message specifying a number of transmissions of a broadcast of a firmware file; broadcasting setup information from the BRFU setup message on a first channel to downstream devices, the setup information specifying at least one other channel to which each downstream device should listen to receive a copy of the firmware file; and repeatedly broadcasting the firmware file to the downstream devices in accordance with the BRFU setup message.
Claims22
A method of managing firmware update communications between devices in a communication system, comprising the steps of:
- retrieving, at an upstream source, a firmware file from a file storage source;
- sending a broadcast remote firmware update (BRFU) setup message from the upstream source to at least one downstream device, the BRFU setup message specifying a wake time at which downstream devices targeted by the BRFU setup message should wake from a sleeping state to receive a copy of the firmware file, such devices comprising targeted downstream devices, and specifying a channel to which each targeted downstream device should tune after waking;
- and
- sending the copy of the firmware file from the upstream source to at least one transmitting device selected from a hub, a collector, and a repeater.
