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

18、 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 ap

19、proved 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

20、 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 lev

21、el 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 infor

22、mation. 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 allo

23、wed 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 ma

24、naged 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 ETSI ETSI TS 122 250 V13.0.0 (2016-01)53GPP TS 22.250 version 13.0.0 Release 131 Scope The present do

25、cument 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 o

26、perator, 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 functional

27、ity shall not compromise conformance to the requirements of the IMS group management defined in this 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

28、 by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference im

29、plicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR21.905: 3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Vocabulary for 3GPP Specifications 2 3GPP TS 22.141: 3rd Generation Partnership Project;

33、 version 13.0.0 Release 134 IMS group management 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

34、 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 servic

35、es 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 ind

36、ependently of the service being used. In conference call, the control machinery in network would 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

37、 could be created by joining a group. The message distribution would be handled by the messaging 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 featur

38、es and different presence information would be provided to each of the groups. These are only few examples of possible use of IMS group management and they intend to clarify the scope of group management. Figure 1.

Example: group used as a

40、 message delivery list How the group is used within a service is outside the scope of this document 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

41、specific issues and therefore outside the scope of group management. However, all of them could use 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 c

42、onsists of members who may have varying rights for configuring or seeing the group properties. 5 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

43、 are identified for IMS Group Management: a) group administrator; Group administrator shall always 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

44、by default. The entity creating a group becomes a group administrator. b) group member; and Group 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 adminis

45、trators or members). They may or may not be able to use or access group content depending on the 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

46、 group identifier, which may be suggested by the group administrator when creating the group. The 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). MessagingserverD

This could be used for example to describe the type and usage of the group. 2) group properties.

49、 Group properties are: i) group visibility; and Group visibility defines who are able to see the 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
