The present document is part 4 of a multi-part deliverable covering Digital Broadband Cable Access to the Public Telecommunications Network; IP Multimedia
13、Time Critical Services. Full details of the entire series can be found in part 1. Introduction The cable industry in Europe and across other Global regions has already deployed broadband cable television Hybrid Fibre Coax (HFC) data networks running the Cable Modem Protocol. The cable industry is in
14、 the rapid stages of deploying IP Voice and other time critical multimedia services over these broadband cable television networks. The cable industry has recognized the urgent need to develop ETSI Technical Specifications aimed at developing interoperable interface specifications and mechanisms for
15、 the delivery of end-to-end advanced real time IP multimedia time critical services over bi-directional broadband cable networks. IPCablecom is a set of protocols and associated element functional requirements developed to deliver Quality of Service (QoS) enhanced secure IP multimedia time critical
16、communications services using packetized data transmission technology to a consumers home over the broadband cable television Hybrid Fibre/Coaxial (HFC) data network running the Cable Modem protocol. IPCablecom utilizes a network superstructure that overlays the two-way data-ready cable television n
17、etwork. While the initial service offerings in the IPCablecom product line are anticipated to be Packet Voice, the long-term project vision encompasses packet video and a large family of other packet-based services. The cable industry is a global market and therefore the ETSI standards are developed
18、 to align with standards either already developed or under development in other regions. The ETSI Specifications are consistent with the CableLabs/PacketCable set of specifications as published by the SCTE. An agreement has been established between ETSI and SCTE in the US to ensure, where appropriat
19、e, that the release of PacketCable and IPCablecom set of specifications are aligned and to avoid unnecessary duplication. The set of IPCablecom ETSI specifications also refers to ITU-SG9 draft and published recommendations relating to IP Cable Communication. The whole set of multi-part ETSI delivera
20、bles to which the present document belongs specify a Cable Communication Service for the delivery of IP Multimedia Time Critical Services over a HFC Broadband Cable Network to the consumers home cable telecom terminal. “IPCablecom“ also refers to the ETSI working group program that shall define and
21、develop these ETSI deliverables. Many cable television operators are upgrading their facilities to provide two way capability and using this capability to provide high speed IP data services per ITU-T Recommendations J.83 and J.112 1. These operators now want to expand the capability of this deliver
22、y platform to include a variety of time critical services. The present document is one of a series of documents required to achieve this goal. It provides a network based call signalling protocol necessary to establish connections. ETSI ETSI TS 101 909-4 V1.5.2 (2006-08) 5 The present document is pa
23、rt 4 of the series of ETSI deliverables and specifies a profile of an application programming interface, Media Gateway Controller Interface (MGCI), and a corresponding protocol, Media Gateway Control Protocol (MGCP), for controlling Voice over IP (VoIP) embedded clients from external call control el
24、ements. The MGCP assumes a call control architecture where the call control “intelligence“ is outside the media gateway and is handled by external call control elements. The profile, as described in the present document, will be referred to as the Network-based Call Signalling (NCS) Protocol. It is
25、based on the Media Gateway Control Protocol (MGCP) 1.0 RFC 3435, which is the result of a merging of the Simple Gateway Control Protocol, and the IP Device Control (IPDC) family of protocols, as well as additional ideas incorporated during the protocol development process. ETSI ETSI TS 101 909-4 V1.
26、5.2 (2006-08) 6 1 Scope The present document is a multi-part deliverable belonging to IPCablecom. The present part (part 4) specifies a profile of an application programming interface, Media Gateway Controller Interface (MGCI), and a corresponding protocol, Media Gateway Control Protocol (MGCP), for
27、 controlling Voice over IP (VoIP) embedded clients from external call control elements. The MGCP is based on a call control architecture, where the call control “intelligence“ resides outside the gateways and is handled by external call control elements. The profile, as described in the present docu
28、ment, is referred to as the Network Call Signalling (NCS) Protocol. Annex B of the present document specifies an expansion of the NCS protocol to emulate an Access Node of an ETSI compliant local exchange. This annex specifies the mapping of expansion of the NCS protocol to V5.2. Annex F of the pres
29、ent document specifies optional NCS components for the delivery of metering pulses. This multi-part deliverable specifies IPCablecom, a set of protocols and associated element functional requirements. These have been developed to deliver high Quality of Service (QoS), enhanced secure IP multimedia t
30、ime critical communication services to a consumers home over a cable television Hybrid Fibre/Coaxial (HFC) data network. NOTE 1: IPCablecom defines a set of documents in the framework of a network superstructure that overlays the two-way data-ready cable television network, e.g. as specified within
31、ES 201 488 5 and ES 200 800 3. While the initial service offerings in the IPCablecom product line are anticipated to be Packet Voice and Packet Video, the long-term project vision encompasses a large family of packet-based services. This may require in the future, not only careful maintenance contro
32、l but also an extension of the present set of documents. NOTE 2: The present set of documents aims for global acceptance and applicability. It is therefore developed in alignment with standards either already existing or under development in other regions and in International Telecommunications Unio
33、n (ITU). NOTE 3: There may also be relevant equivalent studies on-going in IETF or ITU specific to the needs of European IPCablecom. Where possible ETSI TC AT-D working group for IPCablecom should align annex B package annex or similar packages addressing the specific needs of European IPCablecom wi
34、th work on going in IETF, Cablelabs, or the ITU. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
