This Technical Specification has been produced by the 3 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
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 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
This Technical Specification defines the requirements for the support of IP Multimedia Subsystem (IMS) group
management capability. IMS group management capability provides a possibility to manage network based groups.
IMS group management allows defining different roles and rights to the members of a group, defining group level
information and properties, etc.
The IMS group management is a generic capability that can be utilised together with several different services. Some
examples of the services that can use IMS group management are
- Presence service
Presentity has a control of who is able to see his presence information. The control is carried out via access
control lists, which can be managed with IMS group management. Number of presentities can be subscribed via
a list of presentities. The list can be managed with IMS group management.
- Chat
Administrator of the chat is able to control users that are allowed to participate in the chat. The control is carried
out via access control lists, which can be managed with IMS group management.
- Messaging
In messaging the server may be able to distribute the messages to several recipients based on the delivery list.
The content of the delivery list can be managed with IMS group management.
The above examples show only very limited set of possibilities where IMS group management can be utilised. The use
of IMS group management is not restricted to these

1 Scope
The present document defines the stage one description of the IMS group management. Stage one is the set of
requirements which shall be supported for the provision of IMS group management, seen primarily from the
subscribers' and service providers' points of view.
The TS includes information applicable to network operator, service provider, terminal and network manufacturer.
Additional functionalities not documented in the TS are considered outside the scope of this TS. Such additional
functionality may be on a network-wide basis, nation-wide basis or particular to a group of users. Such additional
functionality shall not compromise conformance to the requirements of the IMS group management defined in this
specification.

4.1 Informative description of group management
This clause has an informative description of the IMS group management and its role in a few service examples.
Furthermore, example characteristics of the group will be described to give an overview of a group and its management.
Group as a concept means a group of persons in this context. Groups can be used by group related services such as
conference calls, presence service (c.f. 3GPP TS 22.141 [2]) and messaging (c.f. 3GPP TS 22.340 [3]). This description

does not cover requirements for group services themselves but only management of the groups that can be utilized by
the group related services. The driver for specifying generic group management is twofold: the same group created by
user (or service provider) can be used in many services and same group management functions can be utilised
independently of the serv
