22、.0 Release 13Foreword This Technical Report has been produced by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document,

23、it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y

24、 the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction In addition to reusing the IMS system as defined by 3GPP, TISPAN is

25、 defining an IMS based Multimedia Telephony service, which is an evolution of the CS based Telephony service provided by traditional ISDNs and PSTNs 2. A similar service, defined by 3GPP, is needed for wireless access to IMS, in order to be able to define services to the end-users, and to support in

26、teroperability in multi-vendor and multi-operator environment and to provide the user with the same experience across the different IP based accesses and domains ETSI ETSI TR 122 973 V13.0.0 (2016-01)63GPP TR 22.973 version 13.0.0 Release 131 Scope This Technical Report defines the IMS Multimedia Te

27、lephony service and associated supplementary services for IMS. It aims to take account and build on the IMS capabilities already provided in 3GPP Release 5 and Release 6. The objective is to define the minimum set of capabilities required in the IP Multimedia Subsystem to secure multi-vendor and mul

28、ti-operator inter-operability for the IMS Multimedia Telephony service and related Supplementary Services. Close cooperation shall be sought with TISPAN. TISPAN requirements, as captured in 2, will be taken into account, and referred to where appropriate. While the user experience for the IMS Multim

29、edia Telephony service is expected to have some similarity to existing telephony services, the richer capabilities of IMS will be exploited. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

36、e description 4.1 General service characteristics The IMS Multimedia Telephony service should allow multimedia conversational communications between two or more users. It provides real time bidirectional conversational transfer of speech, video or optionally other types of data. The IMS Multimedia T

37、elephony service is point to point between terminals communicating , or a terminal and a network entity. This communication is usually symmetrical, but in special cases the media components present in each direction may be different, or they may be the same but with different bit rates and Quality o

38、f Service. An IMS Multimedia Telephony service can start with only one type of media and additional types of media may or may not be added by the users as the communication progress. Therefore a particular IMS Multimedia Telephony service may consist of only one type of media, e.g. speech. The IMS M

39、ultimedia Telephony service is different from other IMS based services, such as Push to Talk over Cellular (PoC). Its characteristics includes the following: - IMS Multimedia Telephony is a service where speech, and speech combined with other media components, is the typical usage but the service is

40、 not limited to always include speech, it also caters for other media or combinations of media (e.g. text and video). - The IMS Multimedia Telephony service includes supplementary services. The behaviour of supplementary services is almost identical to supplementary services for CS voice (TS 11) Not

41、e: Most supplementary services are active in the set-up phase. Mid session supplementary services such as session transfer and session hold exist. - The anticipated usage model is that of traditional telephony: one user connecting to any other user, regardless of operator and access technology 4.2 D

42、efault media handling capabilities of the IMS Multimedia Telephony service The IMS Multimedia Telephony service can support many different types of media and the default set of capabilities include the following: - Full duplex speech - Real time video (simplex, full duplex), synchronized with speech

43、 if present. - Text communication - File transfer, - Video clip sharing, picture sharing, audio clip sharing. Transferred files may be displayed/replayed on receiving terminal for specified file formats. At least one common standardized format (e.g. JPEG, AMR) shall be supported per media type. The

44、IMS Multimedia Telephony service should at least support the following handling of media ETSI ETSI TR 122 973 V13.0.0 (2016-01)83GPP TR 22.973 version 13.0.0 Release 13- Adding and removing individual media to/from a IMS Multimedia Telephony communication 5 Service requirements General service requi

47、specification of the IP Multimedia Subsystem (IMS see 4) 3GPP has created a basis for flexible deployment of a multitude of IP based services. In contrast to GSM, which defined a set of bearer- and teleservices that were complemented by a number of supplementary services, 3GPP did not pursue that bu

48、t rather specified “IP multimedia sessions“ within the concept of IMS. 8.1.2 IMS services An “IP multimedia session“ could carry any combination of media (voice, video, text ) and the services, that make use of these IMS sessions, need not be standardised. However, in the last years non-3GPP standar

49、disation bodies like the Open Mobile Alliance (OMA) have created standards for several IMS based services (e.g. PoC, “Presence Simple“ and others) The user primarily distinguishes, understands and experiences these services, not the sessions therein. For example, PoC may set up a session, that transports voice in just the same way as a IMS Multimedia Telephony service would, but for the user these are two different services. 8.1.3 Supplementary services The user may handle supplementary services to the examples given above differe
