Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Access and Terminals (AT). The present document is part 20, sub-part 1, of a multi-part deliverable. Full

21、 details of the entire series can be found in part 1. The present document is fully in line with initiative “eEurope 2002 - An Information Society For All“, under “The contribution of European standardization to the eEurope Initiative, A rolling Action Plan“ especially under key objectives: 1) A che

22、aper, faster and secure Internet a) Cheaper and faster Internet access b) Secure networks and smart cards 2) Stimulate the use of the Internet a) Accelerating e-commerce b) European digital content for global networks c) Intelligent transport systems Introduction The cable industry in Europe and acr

23、oss other Global regions has already deployed broadband cable television Hybrid Fibre/Coaxial (HFC) data networks running the Cable Modem Protocol. The cable industry is in the rapid stages of deploying IP Voice and other time critical multimedia services over these broadband cable television networ

24、ks. 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 multimedia time critical services over bi-directional broadband cable networks

25、. 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 transmission technology to a consumers home over the broadband cable television Hy

26、brid 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 IPCablecom product line are anticipated to be Packet Voice, the long-term pro

27、ject vision encompasses packet video and a large family of other packet-based services. ETSI ETSI TS 101 909-20-1 V1.1.2 (2005-10) 6 The Cable Industry is a global market and therefore the ETSI standards are developed to align with standards either already developed or under development in other reg

28、ions. The ETSI Specifications are consistent with the CableLabs/ IPCablecom set of specifications as published by the SCTE. An agreement has been established between ETSI and SCTE in the US to ensure, where appropriate, that the release of IPCablecom and IPCablecom set of specifications are aligned

29、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 deliverables to which the present document belongs specify a Cable Communication Service for

30、 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 develop these ETSI deliverables. NOTE: The present document has been restructured to

31、 reflect the changes in the original work item. Sub-part 1: IPCablecom CMS based architecture. The present document contains updated and released information covering the intercept interfaces and consequently the corresponding ASN.1 coding specific to IPCablecom implementation of the ES 201 671 8 HI

32、 specification. The restructuring of this document has been made possible as a result of parallel activity done under STF 261 on the development of TS 101 909-20-2, both documents have been aligned (as necessary) to ensure continuity. This part 20-1 has been renamed to more accurately reflect the sc

33、ope, namely Lawful Interception of Voice Telephony within IPCablecom implementations based upon a CMS architecture. ETSI ETSI TS 101 909-20-1 V1.1.2 (2005-10) 7 1 Scope The present document defines the interception of voice communications within the IPCablecom “NCS“ architecture, using a CMS for cal

34、l control, as identified by a unique address (number) e.g. IUT-T Recommendation E.164 13. The present set of documents specifies IPCablecom, a set of protocols and associated element functional requirements. These have been developed to deliver Quality of Service (QoS), enhanced secure IP multimedia

35、 time critical communication services, using packetized data transmission technology to a consumers home over a cable television Hybrid Fiber/Coaxial (HFC) data network. NOTE 1: IPCablecom set of documents utilize a network superstructure that overlays the two-way data-ready cable television network

36、, e.g. as specified within ES 201 488 12 and ES 200 800 (see bibliography). 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 th

37、e future, not only careful maintenance control, 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 region

38、s and in International Telecommunications Union (ITU). To facilitate maintenance and future enhancements to support other real-time multimedia services the documents consist of multi-parts as detailed in part 1: General. The present document is part 20 and describes a set of generic Lawful Intercept

39、ion (LI) mechanisms relating to IPCablecom. The objective of the present document is to define the implementation of Lawful Interception (LI) requirements within the current IP Core Network model adopted by IPCablecom. The specific deployments, where based on national variants or requirements (such

40、as charging, applicability rules, privacy rules, etc.) or operation aspects based on vendor specific implementation (such as administration, bundling of functions into components, deployment concerns) are outside the scope of this generic document. NOTE 3: The present document neither defines the ev

41、ents nor the information to be provided to the handover interface, this will be included in the next edition. Lawful Interception in the Line Control Signalling (LCS) Architecture (TS 101 909-23 4), which uses V 5.2 to Local Exchange (LE) is entirely handled by the LE and has no impact. 2 References
