Introduction This Technical Specification defines the requirements for the support of IP Multimedia Subsystem (IMS) group management capability.
22、 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 utilis
23、ed 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 manage
24、ment. 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 manag
25、ed 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 I
26、MS group management can be utilised. The use of IMS group management is not restricted to these ETSI ETSI TS 122 250 V15.0.0 (2018-07)53GPP TS 22.250 version 15.0.0 Release 151 Scope The present document defines the stage one description of the IMS group management. Stage one is the set of requireme
27、nts 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
28、 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 sp
29、ecification. 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 referenc
30、e, 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 implicitly refers to the latest version of that document in the same Release as the present document. 1 3

35、n 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.
36、3GPP TS 22.141 2) and messaging (c.f. 3GPP TS 22.340 3). This description ETSI ETSI TS 122 250 V15.0.0 (2018-07)63GPP TS 22.250 version 15.0.0 Release 15does not cover requirements for group services themselves but only management of the groups that can be utilized by the group related services. The
37、 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 use a
38、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 server
39、. 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 examp
40、les 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 Figure 2. Example: group used as a message delivery list Chat serverAccess list:BobJackMarcI want to let Bob, Jack and Marc to join this chat, th

43、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 use groups managed by generic
44、 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 High level requirements 5.1
45、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 always have the full set of right
46、s 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 member rights shall be assi
47、gned 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 group specific information.
48、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 IMS service provider alloca
49、tes 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). b) group specific information; and Group specific information 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 group identifier when performing a search. The
