Definitions

• Hybrid fiber coaxial (HFC) networks are rapidly evolving to support a variety of telecommunications services in addition to traditional broadcast-type video services.
• HFC networks are being utilized to provide data services, including high speed
• DOCSIS Media Gateway Control Protocol
• MGCP Media Gateway Control Protocol
• POTS card With a POTS card in place, an interface to a twisted-wire pair is provided and telephones in the residence can be used in a conventional manner, with all of the phones connected to a single twisted- wire pair connected in a bus configuration to the phone outlets throughout the building.
• "home run" wiring may be utilized, with point-to- point connections being established between a centralized location and a particular telephone outlet or set of outlets.
• the advantage of home run wiring is that several phone lines can easily be supported in the home, and phones in one area can be assigned one telephone number, distinct from other numbers used for phones in other areas.
• Multiple POTS cards are typically used to support multiple telephone lines.
• FIG. 1 contains a simplified network architecture of a prior art arrangement for providing communication between a residence and an HFC network;
• FIG. 7 contains a call flow diagram for establishing voice communication between an HFC network and an IEEE 1394-based (Fire Wire) in-home network;
• FIG. 8 illustrates an exemplary protocol stack for an HNG interface between an HFC network and a Bluetooth-based in-home network
• HNG 30 is provided with network management functionality including "device discovery", configuration, and management services and resources management for insuring service quality in the home network.
• Device discovery can be performed using discovery protocols supported by the home network 15. This functionality allows HNG 30 to discover the devices present in the home network 15.
• HNG 30 Other functionality that can be implemented inside the HNG 30 includes routing and bridging among in-home network-attached devices and service-specific metering for billing purposes, hi this embodiment, the HNG 30 communicates with a centralized billing service to control service usage by time, by bytes, or by calls. Additionally, an HNG 30 formed in accordance with the present invention may use tunneling or other well-known protocols to support virtual private network (VPN) technology, hi this embodiment, the HNG 30 performs service-specific privacy management, allowing for businesses to extend their network to other locations by securely transmitting the data via the HFC network 14.
• VPN virtual private network
• an HNG 30 formed in accordance with the present invention can support the "discovery" of a device connected to the home network 15 via an in-home networking protocol (step 70), and can also report the presence of this device to an NMS/EMS 68 (see FIG.3), for the purposes of inventory management (step 72, FIG.4).
• this may include the ability to determine if the subscriber has paid for and is authorized to receive a particular service. The device may then request a particular service
• NMS/EMS 68 to detenrrine if this particular device/service may utilize the requested bandwidth (step 96) and upon receiving authorization, the device contacts CMTS 12 for the bandwidth (step 98), where CMTS 12 then allocates the requested bandwidth on the HFC network 14 (step 100). HNG 30 will then, in turn, allocate the requested bandwidth on the in-home network 15 to the requesting device (step 102).
• telephony application 138 receives signaling, voice or DOCSIS packets from HFC network 132 and generates, through a translator function 140, equivalent packets for transmission to a device attached to 1394-based network 136.
• a ringing request received from MGCP layer 124 is translated into a 1394 packet pre- configured for ringing the destination device.
• destination HNG T after reserving resources inside the home network, exchanges messages with the CMTS Dynamic Service Addition (DSA) to reserve resources inside the HFC network (J).
• DSA CMTS Dynamic Service Addition
• originating CMS 0 sends a modify-connections (MDCX) request to calling HNG 0 to reserve resources in the home network (K).
• MDCX modify-connections
• DEVICE 0 and HNG 0 also reserve resources through its IRM, as shown in FIG. 7 (L).
• Originating HNG 0 also reserves resources through the CMTS before a ringing request (RQNT) is sent to destination HNG T (M).
• the call flow illustrated in FIG. 7 shows only the signaling between the in-home device, the HNG 30, the CMS 16 and the CMTS 12. It is to be understood that additional signaling, well-known in the art and not shown here, is performed between the originating
• SCO link is also estabhshed by HNG 0 prior to accepting the call.
• HNG or Bluetooth telephone device commits to use the parameters indicated in the bearer capability element of the TCS-SETUP message.
