32、S 21.905 1. 1 Closed User Group (CUG) 1.1 Definition The Closed User Group (CUG) Supplementary Service enables subscribers, connected to a PLMN and possibly also other networks, to form closed user groups (CUGs) to and from which access is restricted. A specific user may be a member of one or more C
33、UGs. Members of a specific CUG can communicate among each other but not, in general, with users outside the group. The ability to set up emergency calls remains unaffected. 1.2 Description 1.2.1 Service description An ISDN/MSISDN number shall identify each member of a CUG. A CUG shall be defined for
34、 one or more basic service groups. ETSI ETSI TS 122 085 V15.0.0 (2018-07)63GPP TS 22.085 version 15.0.0 Release 15CUG members can have additional capabilities that allow them to originate calls outside the group, and/or to receive calls from outside the group. CUG members can have additional restric
35、tions that prevent them from originating calls to other members of the CUG, or from receiving calls from other members of the CUG. CUG shall remain unaffected when members roam to PLMNs supporting CUG. Roaming subscribers must have the same CUG facilities on the roamed-to PLMN as on the Home PLMN. W
36、hen roaming to networks not supporting CUG, the CUG restrictions must be enforced. (However, where possible, the CUG facilities should be supported, see subclause 1.4.10.) Each individual subscriber may be a member of a maximum of 10 CUGs. 1.2.2 Applicability to telecommunication services The applic
37、ability of this Supplementary Service is defined in 3GPP TS 22.004 2. 1.2.3 Definitions MSISDN: A number conforming to the numbering plan and structure specified in 3GPP TS 23.003. CUG member: A user who has subscribed to the CUG Supplementary Service and is one of the users in the group formed by a
38、 particular CUG. CUG index: A value assigned by the network to identify a CUG. CUG Interlock Code (IC): Is used by the network (not by the MS) to identify CUG membership. preferential CUG: A preferential CUG, which can be specified for each basic service group, is the nominated default CUG to be use
39、d when no explicit CUG index is received by the network. suppress preferential CUG: A user action to prohibit the use of the preferential CUG, on a per call basis. Incoming Access (IA): An arrangement which allows a member of a CUG to receive calls from outside the CUG. Outgoing Access (OA): An arra
40、ngement which allows a member of a CUG to place calls outside the CUG. suppress OA: A user action to prohibit the use of the OA subscription option, on a per call basis. Incoming Calls Barred Within A CUG (ICB): An access restriction that prevents a CUG member from receiving calls from other members
41、 of that group. Outgoing Calls Barred Within A CUG (OCB): An access restriction that prevents a CUG member from placing calls to other members of that group. CUG calls: A CUG call is a call which is restricted to a pre-defined group of users. 1.3 Normal procedures with successful outcome 1.3.1 Provi
42、sion The CUG Supplementary Service shall be provided after prior arrangement with the service provider. At provision subscription options should be selected by the served mobile subscriber. A user may be a member of several CUGs. The service provider defines the number of CUGs, up to the maximum sta
43、ted in subclause 1.2.1, which can be allocated to an individual subscriber. The user shall choose one of the following subscription options for each basic service group applied to the CUG Supplementary Service. This subscription option may be provisioned on a per basic service group basis or for all
44、 basic services: - CUG calls only; - CUG with incoming access, i.e. can also receive calls, which are not subject to CUG restrictions; - CUG with outgoing access, i.e. can also make calls, which are not subject to CUG restrictions; ETSI ETSI TS 122 085 V15.0.0 (2018-07)73GPP TS 22.085 version 15.0.0
45、 Release 15- CUG with incoming and outgoing access, i.e. can also make and receive calls, which are not subject to CUG restrictions. A user may subscribe to one of two additional restrictions applying for each particular CUG: - incoming calls barred within a CUG; - outgoing calls barred within a CUG
46、. The network shall provide a subscription option in order to enable the user to specify a preferential CUG, for each basic service group included in at least one of the CUG(s). The user can request that no preferential CUG exists, or that a particular one of her CUGs (or the only one if a single CU
47、G applies) is used as a preferential CUG for the particular basic service group. If a user has the subscription option outgoing calls barred within a CUG, it is not allowed to specify that particular CUG as a preferential CUG. The subscription options are shown in Annex 1. The CUG indices shall be a
48、llocated by prior arrangement with the service provider. The choice of preferential CUG(s) shall be alterable only by service provider action upon request by the served user. 1.3.2 Withdrawal Withdrawal of the CUG Supplementary Service, membership of one or more CUGs, will be by the action of the se
49、rvice provider, at the request of the subscriber or CUG management, or for administrative reasons. 1.3.5 Activation The CUG Supplementary Service will be activated by the service provider as a result of provision. 1.3.6 Deactivation The CUG Supplementary Service will be deactivated by the service provider as a result of withdrawal. 1.3.7 Invocation Normal call setup procedures shall apply to calls with the CUG Supplementary Service. 1.3.8 Normal operation with successful outcome A user having neither the restriction of incoming calls barred within a CU
