The present document specifies the procedures used at the radio interface (Reference point Um as defined in 3GPP TS 24.002) for normal operation and invocation of MultiParty supplementary services.

In 3GPP TS 24.010 the general aspects of the specification of supplementary services at the layer 3 radio interface are given.

3GPP TS 24.080 specifies the formats and coding for the supplementary services.

Definitions and descriptions of supplementary services are given in 3GPP TS 22.004 and the 3GPP TS 22.08x and 3GPP TS 22.09x‑series.

3GPP TS 22.084 is related specially to MultiParty supplementary services.

Technical realization of supplementary services is described in 3GPP TS 23.011 and the 3GPP TS 23.08x and 3GPP TS 23.09x‑series.

3GPP TS 23.084 is related specially to MultiParty supplementary services.

The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3 radio interface are defined in 3GPP TS 24.007 and 3GPP TS 24.008.

The following supplementary service belongs to the MultiParty supplementary services and is described in the present document:

– MultiParty service (MPTY) (clause 1).
