0  IntroductionWord‑p. 4
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
