11、roduction The cable industry in Europe and across other regions have already deployed broadband cable television Hybrid Fibre Coax (HFC) data networks running Protocols like the ones specified in ES 201 488 2 or ES 200 800 3. The Cable Industry is in the rapid stages of deploying IP Voice and other

12、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 the delivery of end to end advanced real time IP

13、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 communications services using packetized data tran

14、smission 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 network. While the initial service offerings in the

15、 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 to align to the extent possible with standards ei

16、ther already developed or under development in other regions. The ETSI Specifications are consistent to the extent possible 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 appropriate, t

17、hat 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 IPCablecom ETSI d

18、eliverables 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. ETSI ETSI TS 101 909-1 V1.4.1 (2006-04) 6 1 Scope The present set of docum

NOTE 1: IPCablecom set of documents utilize a network superstructure that overlays the two-way data-ready cable television network, e.g. as specified within ES 201 488 2 and ES 200 800 3. While the initial service offerings in the IPCablecom pr

21、oduct 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 control, but also an extension of the present set of documents. NOTE 2: The present set of do

22、cuments 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 Union (ITU). The present document is part 1 of the above mentioned series of ETSI delivera

31、ial File Transfer Protocol TGCP Trunking Gateway Control Protocol 4 Overview of the multi-part deliverable The TS 101 909 series together present an IPCablecom network architecture for the provision of voice and multimedia IP services. The TS 101 909 series of standards represent a set of cohesive s

32、et of interwoven specifications that jointly evolved to present different phases of IPCablecom network developments. Changes made to one part of the series have to identify the consequence to other parts of the series to ensure the elements interface together properly. 4.1 Part 1: General The presen

33、t document. 4.2 Part 2: Architectural framework Defines architecture framework for IPCablecom networks including all major system components and network interfaces necessary for delivery of IPCablecom services. 4.3 Part 3: Audio Codec Requirements Defines the audio and video codecs necessary to prov

34、ide the highest quality and the most resource-efficient service delivery to the customer. Also specifies the performance required in client devices to support future IPCablecom codecs and describes suggested methodology for optimal network support for codecs. Offering a competitive and/or superior p

35、roduct requires support for more than high-quality delivery of audio. In addition to features and signalling capabilities, which are beyond the scope of this document, the audio codec application must provide transparent support for certain audio features. These include general detection mechanisms,

36、 DTMF, fax, analog modem, echo cancellation, and hearing-impaired support. ETSI ETSI TS 101 909-1 V1.4.1 (2006-04) 8 4.4 Part 4: Network Call Signalling Protocol ETSI TS 101 909-4 adopts ITU-T Recommendation J.162 with some ETSI extensions defined within TS 101 909-4. This part specifies a profile o

37、f 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 elements. The MGCP is based on a call control architecture, where t

38、he call control “intelligence“ resides outside the gateways and is handled by external call control elements. The profile, as described in TS 101 909-4, is referred to as the Network Call Signalling (NCS) Protocol. 4.5 Part 5: Dynamic Quality of Service Defines the QoS Architecture for the “Access“

39、portion of the IPCablecom network, provided to requesting applications on a per-flow basis. The access portion of the network is defined to be between the Multimedia Terminal Adapter (MTA) and the Cable Modem Termination System (CMTS). The method of QoS allocation over the backbone is unspecified in

40、 the present edition of TS 101 909-5. The Dynamic QoS specification incorporates protocols to enable providers of packet-based voice communications using the IPCablecom framework to use different charging models, including both flat-rate charging as well as usage-based charging. It is the intent of

41、TS 101 909-5 to ensure that enhanced QoS is provided only to authorized and authenticated users. The Dynamic QoS specification recognizes the requirements of a commercially viable voice communications service analogous to that offered by means of the public switched telephone network. It is importan

42、t to ensure that resources are available before the two parties involved in the session are invited to communicate. Thus, resources are reserved before the recipient of the communication is notified that someone is trying to initiate a communication. If there are insufficient resources for a session

43、, then the session is blocked. 4.6 Part 6: Media Terminal Adapter (MTA) device provisioning ETSI TS 101 909-6 adopts ITU-T Recommendation J.167 with some ETSI extensions defined within TS 101 909-6. This part defines the protocol mechanisms for provisioning of an IPCablecom embedded-MTA device by a

44、single provisioning and network management provider. 4.7 Part 7: Management Information Base (MIB) Framework Describes the framework in which IPCablecom MIBs (Management Information Base) are defined. It provides information on the management requirements of IPCablecom specified devices and function

45、s, and how these requirements are supported in the MIB. It is intended to support and complement the actual MIB documents, which are issued separately. The original ETSI published version of TS 101 909-7 defined the MIB in full. However, in later versions of TS 101 909-7 reference to the latest IETF

46、 IPCDN published MIB was used. 4.8 Part 8: Media Terminal Adapter (MTA) Management Information Base (MIB) Defines the MIB module which supplies the basic management objects for the MTA Device. The original ETSI published version of TS 101 909-8 defined the MIB in full. However, in later versions of

47、TS 101 909-8 reference to the latest IETF IPCDN published MIB was used. ETSI ETSI TS 101 909-1 V1.4.1 (2006-04) 9 4.9 Part 9: Network Call Signalling (NCS) MIB Requirements Defines the MIB module which supplies the basic management object for the NCS protocol. The original ETSI published version of

48、TS 101 909-8 defined the MIB in full. However, in later versions of TS 101 909-8 reference to the latest IETF IPCDN published MIB was used. 4.10 Part 10: Event Message Requirements Defines the concept of Event Messages used to collect usage for the purposes of billing within the IPCablecom architect

49、ure. An Event Message is a data record containing information about network usage and activities. A single Event Message may contain a complete set of data regarding usage or it may only contain part of the total usage information. When correlated by the Record Keeping System (RKS), information contained in multiple Event Messages provides a complete record of the service. This complete record of the service is often referred to as a Call Detail Record (CDR). Event Messages or CDRs may be sent to one or more back office applications such as a billing system,
