Method of setting and changing receive channel set of cable modem
First Claim
1. A method of setting a Receive Channel Set (RCS) of a Cable Modem Termination System (CMTS), the method comprising:
- receiving a Receive Channel Profile (RCP) with respect to a downstream physical layer of a cable modem (CM);
composing a plurality of Receive Channel Configurations (RCCs) required for setting the RCS of the CM with reference to the RCP, the plurality of RCCs including at least an RCC for initial setting of the RCS and an RCC for a subsequent setting of the RCS in the event that the initial setting fails; and
encoding the plurality of RCCs, and transmitting the encoded plurality of RCCs to the CM in a registration response transmitted after each of the plurality of RCCs are composed, wherein the encoded plurality of RCCs including the RCC for initial setting of the RCS and the RCC for the subsequent setting of the RCS in the event that the initial setting fails is sent in the registration response before receiving a Registration Acknowledge from the CM.

Abstract
A method of effectively setting and changing a Receive Channel Set (RCS) of a cable modem (CM) is provided. The method includes: receiving, by a Cable Modem Termination System (CMTS), a Receive Channel Profile (RCP) with respect to a downstream physical layer of a CM; composing, by the CMTS, a plurality of channel configuration information required for setting the RCS of the CM with reference to the RCP; encoding, by the CMTS, the plurality of channel configuration information, and transmitting the encoded plurality of channel configuration information to the CM; transmitting, by the CM, an RCP with respect to a downstream physical layer to a CMTS; receiving, by the CM, a plurality of channel configuration information being composed with reference to the RCP and being required for setting the RCS; and setting, by the CM, the RCS using the plurality of channel configuration information.

6. A method of setting a Receive Channel Set (RCS) of a cable modem (CM), the method comprising:
-
transmitting a Receive Channel Profile (RCP) with respect to a downstream physical layer to a Cable Modem Termination System (CMTS); receiving a plurality of Receive Channel Configurations (RCCs) being composed with reference to the RCP, being required for setting the RCS, and including at least an RCC for initial setting of the RCS and an RCC for subsequent setting of the RCS in the event that the initial setting fails, wherein the plurality of RCCs including at least the RCC for initial setting of the RCS and the RCC for subsequent setting of the RCS are received before sending a Registration Acknowledgement or a change response to the CMTS; and after receiving the plurality of RCCs including the RCC for initial setting of the RCS and the RCC for subsequent setting of the RCS, setting the RCS using the plurality of RCCs, wherein the setting the RCS includes attempting an initial setting of the RCS using the RCC for initial setting of the RCS, and when the initial setting of the RCS fails, attempting another setting of the RCS using the RCC for subsequent setting of the RCS. - View Dependent Claims (7)

8. A method of changing a Receive Channel Set (RCS) of a Cable Modem Termination System (CMTS), the method comprising:
-
determining whether a predetermined RCS of a cable modem (CM) is changed; composing a plurality of Receive Channel Configurations (RCCs) required for changing the RCS with reference to an RCP with respect to a downstream physical layer of the CM, the plurality of RCCs including at least an RCC for initial setting of the RCS and an RCC for a subsequent setting of the RCS in the event that the initial setting fails; and encoding the plurality of RCCs based on a priority, and transmitting the encoded plurality of RCCs to the CM in a change request transmitted after each of the plurality of RCCs are composed, wherein the encoded plurality of RCCs including the RCC for initial setting of the RCS and the RCC for the subsequent setting of the RCS in the event that the initial setting fails is sent in the change request before receiving a change response from the CM. - View Dependent Claims (9)
