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.

The presentation invention relates to methods and apparatus for coordinating the buffering and transmission of data between a Cable Modem Termination System (CMTS) and a wireless base station.

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.

Systems and methods are provided herein for providing a system to reconfigure a user's access network to provide varying quality of service (QOS) based on flow identification. For example, a policy server (PS) may transmit a plurality of addresses of virtual private network (VPN) servers associated with a priority status to a cable modem (CM) and / or cable modem termination system (CMTS) associated with a client device. The CMTS may notify the PS when the CM and / or CMTS detects VPN traffic between the client device and a VPN server associated with the priority status. In response to the notification, the PS may transmit an update message to the CMTS, wherein the update message comprises an updated configuration. The updated configuration may be used to update the CM and / or CMTS so that the updated CM and / or CMTS process future data packets according to an updated QoS policy.
