6 results about "Cable modem termination system" patented technology

A cable modem termination system or CMTS is a piece of equipment, typically located in a cable company's headend or hubsite, which is used to provide high speed data services, such as cable Internet or Voice over Internet Protocol, to cable subscribers. A CMTS provides many of the same functions provided by the DSLAM in a DSL system.

Implementing dynamic service flows in cable convergence network

Embodiments of the present disclosure relate to implementing dynamic service flows in a cable convergence network. An access gateway function (AGF) device receives quality of service (QoS) information associated with a packet data unit (PDU) session of a cable modem device from an access and mobility management function (AMF) device of a core network. The AGF device determines QoS matching criterion information based on the QoS information. The AGF device sends a service flow creation message to a cable modem termination system (CMTS) associated with the cable modem device over an interface between the AGF device and the CMTS, such as a General Open Policy Service (COPS) interface, the service flow creation message including QoS matching criterion information. Sending a service flow creation message enables the CMTS to create a first service flow between the CMTS and the cable modem device, and enables the cable modem device to create a second service flow between the cable modem device and the CMTS.

Methods and Systems For Monitoring Upstream Communication Channels in a Cable Service Network

Various embodiments include methods and devices that enable cable modems or network elements to monitor upstream channels for communications between cable modems and the Cable Modem Termination System (CMTS) and prompt the CMTS to impair an upstream channel with an error rate exceeding a threshold. In some embodiments, cable modems or a network element may periodically request Forward Error Correction (FEC) data from the CMTS and identify whether an upstream channel should be impaired based on predefined error rate thresholds. If an upstream channel is found to have error rates exceeding an acceptable error rate threshold, the cable modem or network element may signal the CMTS to impair that channel. Additionally, the cable modem or network element may continue to monitor impaired upstream channels and signal the CMTS to recover channels that exhibit error rates less than corresponding thresholds.

Enabling dynamic service flows in cable convergence networks

An access gateway function (AGF) device receives, from an access and mobility management function (AMF) device of a core network, quality of service (QoS) information associated with a packet data unit (PDU) session of a cable modem device. The AGF device determines, based on the QoS information, QoS match criteria information. The AGF device sends, to a cable modem termination system (CMTS) associated with the cable modem device and via an interface, such as a common open policy service (COPS) interface, between the AGF device and the CMTS, a service flow creation message that includes the QoS match criteria information. Sending the service flow creation message enables the CMTS to create a first service flow between the CMTS and the cable modem device, and the cable modem device to create a second service flow between the cable modem device and the CMTS.
