4 Message Waiting Indication (MWI)
4.1 Introduction
The Message Waiting Indication (MWI) service enables the network, upon the request of a controlling user to indicate
to the receiving user, that there is at least one message waiting.
4.2 Description
4.2.1 General description
The MWI service enables the AS to indicate to the subscriber, that there is at least one message waiting.
The indication is delivered to the subscriber's UE after successful subscription to the Message Waiting Indication
service as described in the present document.
Other modes of MWI service invocation are not applicable.
NOTE: Having received this indication, the subscriber user can subsequently access the message account, to have
the deposited message delivered. The means by which the subscriber accesses and manages the message
account are outside the scope of the present document.
4.3 Functional entities
4.3.1 User Equipment (UE)
The UE shall implement the MWI Subscriber User Agent role as described in subclause 4.4.1.
4.3.2 Application Server (AS)
An AS shall implement the role of a MWI Notifier User Agent as described in subclause 4.4.2.
An AS implementing the role of MWI Notifier User Agent shall implement the role of the AS acting as terminating UA
as described in 3GPP TS 24.229 [2], subclause 5.7.2.
Additionally an AS may implement other roles for the receipt and storage of the messages for example Web Server,
Mail Transfer and Delivery Agent, Short Message Service centre, etc.
The definition of additional roles for an MWI AS is out of the scope for the current specification.
4.4 Roles
4.4.1 MWI Subscriber User Agent (MSUA)
A MSUA is an entity that is subscribed or requests information about status change of message account from an MWI
AS.
Actions performed by a MSUA as a part of the UE are described in subclause 4.7.2.1.
4.4.2 MWI Notifier User Agent (MNUA)
The MNUA is an entity that provides information about changes in message account status to the MSUA.
Actions performed by a MWI Notifier User Agent as a part of the AS are described in subclause 4.7.2.5.
4.4.3 Message Account (MA)
4.4.3.0 General
The definition of the message account from the RFC 3842 [3] applies with following additions:
ETSI

3GPP TS 24.606 version 15.0.0 Release 15 9 ETSI TS 124 606 V15.0.0 (2018-07)
Message account retains multimedia messages (e.g. voice, video and fax) intended to a particular subscriber.
4.4.3.1 Identification of the message account for the message deposit
Since messages may be intended to the different public user identities that belong to the same subscriber, the message
account may be configured to retain messages for any of the subscriber's public user identities.
Configuration of a message account to retain messages for each public user identity, for a group of public user identities
or for all of public user identities that belong to the same subscriber is subject to the operator's policy.
4.4.3.2 Identification of the message account for the MWI subscription
For the identification of the message account by subscriptions to the MWI service any of a subscriber's public user
identities can be used (see examples in subclause A.1.1.2).
4.5 Operational requirements
4.5.1 Provision/withdrawal
The MWI service is provided after prior arrangement with the service provider. The MWI service shall be withdrawn at
the subscriber's request or for administrative reasons.
Any of the subscriber's public user identities can be used to access the MWI service, see annex B.
4.5.2 Requirements on the originating network side
No specific requirements are needed on the originating network side.
NOTE: Annex B includes an example of an iFC that can be used to invoke the MWI supplementary service.
4.5.3 Requirements in the network
No specific requirements are needed in the network.
4.5.4 Requirements on the terminating network side
No specific requirements are needed in the network.
4.6 Coding requirements
The application/simple-message-summary MIME type used to provide Message Summary and Message Waiting
Indication Information is defined in subclause 5 of RFC 3842 [3].
The coding of the message types in the message-context-class values is defined in the specifications listed in the
"reference" column of table 1.
