Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying chan
18、ge 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 substa

Introduction This Technical Specification defines the requirements for the support of IP Multimedia Subsystem (IMS) group management capab
20、ility. 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
21、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
22、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
23、 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 w
24、here IMS group management can be utilised. The use of IMS group management is not restricted to these ETSI ETSI TS 122 250 V14.0.0 (2017-03)53GPP TS 22.250 version 14.0.0 Release 141 Scope The present document defines the stage one description of the IMS group management. Stage one is the set of req
25、uirements 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 docu
26、mented 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 t
27、his specification. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific re
28、ference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.

33、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 ca
34、n 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 service
35、s. 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 service being used. In conference call, the control machinery in network would
36、use a group to setup a conference call and distribution of group media. In messaging area, group management could be utilized in chat sessions (Figure 1) and distribution lists (Figure 2). A chat session could be created by joining a group. The message distribution would be handled by the messaging
37、server. The user would send messages to a group and the server would distribute the messages. In the context of presence service, the user could create groups of watchers with the group management features and different presence information would be provided to each of the groups. These are only few
38、 examples of possible use of IMS group management and they intend to clarify the scope of group management. Figure 1. Example: groups in context of chat service Chat serverAccess list:BobJackMarcI want to let Bob, Jack and Marc to join this chat, that I controlling.Use IMS group management to add Bo

Example: group used as a message delivery list How the group is used within a service is outside the scope of this docume
40、nt and outside the scope of group management. For example, taking part in a chat session, making a conference call and give access to certain attributes of the presence information are all group service specific issues and therefore outside the scope of group management. However, all of them could u
41、se groups managed by generic IMS group management. The IMS group management is a common set of actions that can be taken by the group administrator of a group or the group members. Typically, the group consists of members who may have varying rights for configuring or seeing the group properties. 5
42、High level requirements 5.1 Group management roles The IMS group management shall provide the ability for users to create groups that can be utilized in context of different services. The following roles are identified for IMS Group Management: a) group administrator; Group administrator shall alway
43、s have the full set of rights for viewing and managing the group and member properties. Each group shall have at least one group administrator at all times. The group administrator is not a group member by default. The entity creating a group becomes a group administrator. b) group member; and Group
44、 member rights shall be assigned by the one who has rights to do that. Group member can be another group. c) others. These are services and entities that are external to the group (i.e. not group administrators or members). They may or may not be able to use or access group content depending on the
45、group specific information. 5.2 General requirements The groups controlled by the IMS group management shall be associated with a) a group identifier; Each group shall have a globally unique, addressable group identifier, which may be suggested by the group administrator when creating the group. The
46、 IMS service provider allocates group identifier. The group identifier is used to refer to a specific group (for example when sending a message, when updating the list of group members).

48、ation is divided into two parts 1) group information; and The group information contains informative text. This could be used for example to describe the type and usage of the group. 2) group properties. Group properties are: i) group visibility; and Group visibility defines who are able to see the
49、group identifier when performing a search. The following classes exist: - only the group administrators; and - the group administrators and the group members. ii) group duration. Once created, a group will exist until either: - its expiration time; or - administratively removed. c) service specific group information. The service specific group information may give additional information on how the group should be used in the context of a specific service. For example, it may indicate that the group shall be used as an access list in the context of the pr
