Abstract
An apparatus, method and system are provided for multimedia access network channel management, such as channel management in a hybrid fiber-coaxial cable network, for voice (telephony), video, fax and data transmission. The preferred system embodiment includes a plurality of cable telephony modems (CTMs), for such voice (telephony), video, fax and data transmission, and includes a cable modem termination system (CMTS). For upstream communication from the CTMs to the CMTS, the network provides a plurality of channels, formed by a combination of FDM and TDMA. When a CMTS receives an multimedia network access message having a comparative priority from a CTM, the CMTS determines whether there is a first channel which is available from the plurality of channels, and if so, assigns a first transmission corresponding to the multimedia network access message to the first channel. When there is no available first channel, the CMTS determines whether there is a second transmission on a second channel which is moveable to a third channel, and if so, reassigns the second transmission to the third channel and assigns the first transmission corresponding to the multimedia network access message to the second channel. When there is no available first channel and no second transmission which is moveable, the CMTS determines whether there is a third transmission on an assigned channel having a lower comparative priority than the comparative priority of the multimedia network access message, and when there is a third transmission, the CMTS removes the third transmission from the assigned channel to form a vacated channel, and assigns the transmission corresponding to the multimedia network access message to the vacated channel.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
