Patent ID: 8045578

Claim:
A method of controlling an event of a cable modem at a cable modem termination system (CMTS), the method comprising: determining whether to periodically allocate a transmission bandwidth of a CM-STATUS message with respect to an event occurrence of the cable modem; setting an event control encoding that includes information regarding whether to periodically allocate the transmission bandwidth, setting a bandwidth allocation bit to a first value that is a polling mode, when it is determined to periodically allocate the transmission bandwidth, wherein the bandwidth allocation bit indicates whether to periodically allocate the transmission bandwidth; and setting the bandwidth allocation bit to a second value that is a contention mode, when it is determined to not periodically allocate the transmission bandwidth, wherein the bandwidth allocation bit indicates whether to periodically allocate the transmission bandwidth; and generating a MAC Domain Descriptor (MDD) message containing the event control encoding to transmit the generated MDD message.
