| 영문내용요약 | The present document specifies a client for the Multimedia Telephony Service for IMS (MTSI) supporting conversational speech (including DTMF), video and text transported over RTP with the scope to deliver a user experience equivalent to or better than that of Circuit Switched (CS) conversational services using the same amount of network resources. It defines media handling (e.g. signalling, transport, jitter buffer management, packet-loss handling, adaptation), as well as interactivity (e.g. adding or dropping media during a call). The focus is to ensure a reliable and interoperable service with a predictable media quality, while allowing for flexibility in the service offerings.
The scope includes maintaining backward compatibility in order to ensure seamless inter-working with existing services available in the CS domain, such as CS speech and video telephony, as well as with terminals of earlier 3GPP releases. In addition, inter-working with traditional PSTN and emerging TISPAN network is covered. The specification is written in a forward-compatible way in order to allow additions of media components and functionality in releases after Release 7. NOTE 1: MTSI clients can support more than conversational speech, video and text, which is the scope of the present document. See 3GPP TS 22.173 [2] for the definition of the Multimedia Telephony Service for IMS. NOTE 2: 3GPP TS 26.235 [3] and 3GPP TS 26.236 [4] do not include the specification of an MTSI client, although they include conversational multimedia applications. Only those parts of 3GPP TS 26.235 [3] and 3GPP TS 26.236 [4] that are specifically referenced by the present document apply to Multimedia Telephony Service for IMS. NOTE 3: The present document was started as a conclusion from the study in 3GPP TR 26.914 [5] on optimization opportunities in Multimedia Telephony for IMS (3GPP TR 22.973 [6]). |
