This Technical Specification (TS) has been produced by the 3rd Generation 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, 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


xthe first digit:

presented to TSG for information;

presented to TSG for approval;

or greater indicates TSG approved document under change control.

Ythe second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc.

zthe third digit is incremented when editorial only changes have been incorporated in the document.


This TS defines the service requirements from users and operators perspective for the support of IP multimedia applications through the IMS.IP multimedia applications are supported by IP multimedia sessions in the IM CN Subsystem. IP multimedia sessions use IP connectivity bearers (e.g. GPRS as a bearer). Examples of IP multimedia applications include speech communication, real time multimedia applications, shared online whiteboards etc.This TS, in general, does not standardise usage of IP multimedia applications, but instead identifies the requirements to enable their support.In order to align IP multimedia applications wherever possible with non-3GPP IP applications, the general approach is to adopt non-3GPP IP based solutions.

The existing legacy tele- and supplementary services shall not be re-standardised as IP multimedia applications, and multimedia equivalent applications may be created with toolkits.


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, edition number, version number, etc.) or nonspecific.

-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 latest version of that document in the same Release as the present document.
