Embodiment

[0023] combined with figure 1 As shown, a method for channel locking and channel bonding based on DOCSIS3.1 system, including:

[0024] 1. Mixed-label channel binding

[0025] For example, if an operator has idle frequency points 100M, 108M, 116M, 124M, 700M, 706M, 712M, 718M, the downlink channel list in the MDD (MACDomain Descriptor MAC Domain Name Descriptor) message is as follows:

[0026] Table 1: List of downlink channels in MDD message

[0027]

[0028]

[0029] CM (Cable Modem) installs TLV format analysis after receiving the MDD message, and the channel list of the transmission line includes both European standard (European standard, 8MHz bandwidth, Annex A) and American standard (American standard, 6MHz bandwidth, Annex B) , in the traditional method, the CM will think that the MDD message has an error and enter the DOCSIS2.0 mode. In the present invention, in the CM, what has both European standard and American standard in the channel list is defined as a m...

Abstract

The invention discloses a DOCSIS3.1 system-based channel locking and binding method, which comprises the following steps that: a CM searches an MDD message from a downlink channel, and when a channellist obtained after the MDD message is analyzed has both an European standard channel and an American standard channel, the channel list is defined as a mixed standard and is recorded as Andex F; theCM starts uplink distance measurement, obtains an IP and a configuration file, enters a registration process after the IP and the configuration file are obtained, encapsulates a receiving channel configuration file RCP to a registration message and sends the registration message; and after the CMTS legality detection is passed, the RCP confirmation is replied, the CM performs hybrid channel locking by adopting tuner anti-initialization and rapid initialization methods according to parameters in the RCP confirmation, and finally, registration and online operation are performed. On the basis ofa DOCSIS3.1 system, a new locking and binding technology is provided, existing European standard frequency points and American standard frequency points are flexibly combined, the channel utilizationrate is increased, high bandwidth is guaranteed, and meanwhile support for existing standards is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cable television, in particular to a channel locking and binding method based on the DOCSIS3.1 system. Background technique [0002] DOCSIS (Data Over Cable Service Interface Specifications) 3.1 system, physical layer LDPC+OFDM+ modulation up to 4096QAM, uplink 1G / downlink 10G, 192MHz per channel, more available physical spectrum: uplink 5~85 / 204MHz, downlink 108 / 258MHz~1288 / 1788MHz. The MAC has also been improved accordingly, and is compatible with D2.0 / 3.0 devices, and can also be integrated into the CCAP platform. In addition, because DOCSIS3.1 adopts advanced ActiveQueueManagement (Active Queue Management) technology, QoS is better, which can significantly reduce network delay. With the use of 5G technology, the integration of 5G and wired access networks has also become a development trend, such as 5G+DOCSIS3.1 backhaul applications. High bandwidth requires more frequency resources, especially in...
