Introduction TISPAN NGN base
23、s the provision of real-time communication services on the 3GPP specified IMS. This is a flexible tool that can provide a wide range of service interactions between terminals and networks. Videotelephony provides a specific use of the generic capabilities of the IMS. The present document provides re
24、quirements to investigate the capabilities of the IMS to provide Videotelephony, and may be used for a “gap analysis“ of the features and capabilities provided by the IMS. The specific services and interactions described in the present document are based on other service specifications. The IMS is a
25、n inherently multimedia service control platform, and should be able to provide all of these services. The interactions between the user and the terminal and the terminal and the network are not provided. The services and capabilities provided by a TISPAN NGN are described in TS 181 005 2. The requi
26、rements for services, described in the present document, also take account of the interactions required between interconnected networks - both between NGN and the interconnection of NGN with legacy networks. The aim of the present document is to assist network operators and service providers to depl
27、oy NGN multimedia services. ETSI ETSI TS 122 401 V8.0.0 (2008-10) 6 3GPP TS 22.401 version 8.0.0 Release 8 1 Scope The present document defines the requirements for a videotelephony service which may be supported by a TISPAN NGN. These requirements form the basis for the definition of network capabi
28、lities. The present document provides interoperability service requirements for interconnection between existing networks and a TISPAN NGN, and between TISPAN NGN. The present document only provides requirements for IP multimedia based networks. Services provided by a TISPAN NGN to support legacy te
29、rminals and interfaces (PSTN/ISDN emulation) are defined in existing PSTN/ISDN documents. Requirements for PSTN/ISDN emulation are out of scope of the present document and are described in other documents. The applicability of PSTN/ISDN simulation services to the videotelephony service requirements
30、are defined in the present document. The requirements in the present document are described from the user point of view. The requirements do not take into account capabilities of existing protocols defined for the IMS. The evolution or modifications to these protocols are beyond the scope of the pre
31、sent document. NOTE: The present document uses the term “NGN“ only in the context of TISPAN. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication
32、, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the

The service
40、 is assumed to be applicable only to dedicated terminal equipment with video capabilities. The videotelephony service may be considered as a specific instance of an IP multimedia service, or as part of the Multimedia Telephony with PSTN/ISDN Simulation Services. 5 Procedures 5.1 General service requ
41、irements The videotelephony service shall conform to the requirements in TS 181 005 2, clause 5.2.1. In particular, the following capabilities described in TS 181 005 2 shall be applicable to this service: Handling of an incoming session (by the terminating entity). Presentation of session originato
42、r identity. Negotiation of an incoming session. Accepting or rejecting an incoming session. Handling of an ongoing session. User modification of media in an ongoing session. Presentation of identity of connected-to party of a session. ETSI ETSI TS 122 401 V8.0.0 (2008-10) 8 3GPP TS 22.401 version 8.

Anonymous Communications Rejection service requirements (ACR). 5.2 Registration, provisioning, activation, invocation and withdrawal The requirements for Registration/Log-out, provisioning, activation, invocation and withdrawal shall be as described in TS 181 005 2. 5.3 Charging and accou
45、nting The requirements for charging and accounting shall be as described in TS 181 005 2. 6 Quality of service requirements 6.1 General The quality of service requirements shall be as described in TS 181 005 2. The following parameters may also be taken into account: Overall Delay, Delay Variation,
46、Differential Delay between sound and image, Sound Quality, Image Quality, Echo Cancellation, Sensitivity to Packet Loss, etc. 6.2 Video quality Four profiles are defined in table 1. Other enhancement or additional functions may be added. Table 1: Video quality profile Profile Description A Basic Vid
47、eotelephony: PCM or equivalent telephony audio, QCIF or CIF video with limited movements capability. B Enhanced Videotelephony: wideband audio, CIF video. The service should be usable for sign language and lip-reading and should provide adequate representation of the fluid movements of a person disp
48、layed in head and shoulders view. Facial expressions shall be clearly recognized. C Television Broadcasting quality. D High Definition Television quality. 6.3 Audio quality Videotelephony does not place any additional requirements for audio quality. ETSI ETSI TS 122 401 V8.0.0 (2008-10) 9 3GPP TS 22
49、.401 version 8.0.0 Release 8 7 Interworking considerations 7.1 General An NGN shall support the interoperability of the videotelephony service with non NGN network services and vice versa. This includes interworking the audio component to the PSTN/ISDN and vice versa. The video component shall only be interworked if video is supported in the non NGN network. The scope of this interworking may result in a limited service capability. 7.2 Interworking with emulation services An NGN shall support the interoperability o
