  • Patent number: 9479544
    Abstract: A Data Over Cable Service Interface Specification (DOCSIS) cable modem system is coupled to: i) via a local area internet protocol (IP) network, a voice over internet protocol (VoIP) device operating Session Initiation Protocol (SIP) for signaling a VoIP session; and ii) via a DOCSIS network, a cable modem termination system (CMTS) via a network. The cable modem system comprises instructions stored in a memory and executed by a processor. The instructions comprise: i) in response to receiving a frame via the local area IP network, determining if the frame is a Session Initiation Protocol (SIP) invite message signaling a VoIP session with a remote endpoint; and ii) in response to determining that the frame is a SIP invite message, generating a DOCSIS message to the CMTS to request an addition of reserved bandwidth on the DOCSIS network for the VoIP session.

  • Patent number: 8346947
    Abstract: A cable modem integrated session border controller operates as a point of demarcation between a local area network (LAN) and a DOCSIS network and, in response to receiving a Session Initiation Protocol (SIP) message, which includes Session Description Protocol (SDP), from a VoIP device coupled to the LAN, communicates with a Cable Modem Termination System (CMTS) to take advantage of DOCSIS Dynamic Quality of Service (DQoS). If required service flow attributes, as determined from the SDP of the SIP message, matches service flow attributes of an existing UGS service flow with a CMTS, a DOCSIS Dynamic Service Change (DSC) request is used to add an additional sub flow to the existing UGS service flow. If attributes fail to match attributes of all existing UGS service flows, a DOCSIS Dynamic Service Change (DSC) request is used to initiate an additional UGS service flow with the required service flow attributes.

  • Publication number: 20120047273
    Abstract: A cable modem integrated session border control circuit operates as a point of demarcation between a local area network (LAN) and a DOCSIS network and, in response to receiving a Session Initiation Protocol (SIP) message, which includes Session Description Protocol (SDP), from a VoIP device coupled to the LAN, communicates with a Cable Modem Termination System (CMTS) to take advantage of DOCSIS Dynamic Quality of Service (DQoS) if a VoIP session between the VoIP device and a remote endpoint includes use of the DOCSIS network.
