Publication number: 20110150058Abstract: Provided is a cable modem control method. The cable modem control method checks upstream parameters which are received by a cable modem termination system to check a status of an upstream channel. The cable modem control method determines whether the upstream channel is good or whether to allow an upstream data transmission of a cable modem on the basis of a result of the check. The cable modem control method suspends the upstream data transmission of the cable modem and performs ranging when the upstream channel is not good as a result of the determination. The cable modem control method postpones bandwidth allocation to a channel of the cable modem and allocates a bandwidth to another usable upstream channel. The cable modem control method returns to a normal status when the ranging is successfully ended.Type: ApplicationFiled: September 21, 2010Publication date: June 23, 2011Applicant: Electronics and Telecommunications Research InstituteInventor: Hye Ju Oh
