Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI).
This ETS describes MultiParty (MPTY) supplementary services within the European digital cellular
telecommunications system (Phase 2) and correspond to GSM technical specification GSM 02.84 version
4.4.6.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI/PNE rules.
Reference is made within this ETS to GSM Technical Specifications (GSM-TSs) (NOTE).
NOTE: TC-SMG has produced documents which give the technical specifications for the
implementation of the European digital cellular telecommunications system.
Historically, these documents have been identified as GSM Technical Specifications
(GSM-TSs). These TSs may have subsequently become I-ETSs (Phase 1), or ETSs
(Phase 2), whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are,
for editorial reasons, still referred to in GSM ETSs.

1 Multi-Party Service (MPTY)
1.1 Definition
This supplementary service provides a mobile subscriber with the ability to have a multi-connection call,
i.e. a simultaneous communication with more than one party.
1.2 Description
1.2.1 Description
A precondition for the multi-party service is that the served mobile subscriber is in control of one active call
and one call on hold, both calls having been answered. In this situation the served mobile subscriber can
request the network to begin the multi-party service.
Once a multi-party call is active, remote parties may be added, disconnected or separated (i.e. removed
from the multi-party call but remain connected to the served mobile subscriber).
The maximum number of remote parties is 5.
1.2.1.1 Indication about multi-party status
Notification shall be sent towards the served mobile subscriber and all the remote parties in a multi-party
call at the invocation of this supplementary service. In addition a notification shall always be sent towards
all remote parties (i.e. not towards the served mobile subscriber) every time a new party is added to the
multi-party call. Notifications shall also be sent to remote parties when they are put on hold and when they
are retrieved in accordance with normal Call Hold procedures.
In the case where a previously private communication is added again to the multi-party call a notification
shall be sent towards all remote parties.
NOTE: During an interim period of time, some networks might not support the sending of the
notifications to the remote parties.
1.2.2 Applicability to telecommunication services
This service is applicable to Telephony (TS 11) only.
1.2.3 Terminology
Served Mobile Subscriber
During the invocation and active phase, the service is under the control of the served mobile subscriber,
i.e. the one who has subscribed to the service.
Remote Party
Any participant in the multi-party call who is not the served mobile subscriber.
1.3 Normal procedures with successful outcome
1.3.1 Provision
This supplementary service is provisioned for all Basic Services subscribed to and to which it is
applicable, i.e. not to any subset of these BS.
The provision of the Call Hold supplem
