25、 V13.0.0 (2016-01)53GPP TS 22.085 version 13.0.0 Release 130 Scope The present document describes the Supplementary Services belonging to the group Community Of Interest Supplementary Services. The general aspects, including definitions and recommended provision, of the description of the Supplement

26、ary Services are given in TS 22.004. The group of Community Of Interest Supplementary Services includes one Supplementary Service: - Closed user group (clause 1). 0.1 References The following documents contain provisions which, through reference in this text, constitute provisions of the present doc

27、ument. References are either specific (identified 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 (inclu

28、ding 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 3GPP TS 21.905: “Vocabulary for 3GPP Specifications“. 2 3GPP TS 22.004: “General on Supplementary Services“. 3 3GPP TS 23.003: “Digital cellular tele

30、tary services Stage 1. 0.2 Abbreviations Abbreviations used in the present document are listed in 3GPP TS 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 use

31、r groups (CUGs) to and from which access is restricted. A specific user may be a member of one or more CUGs. 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. ETSI ETSI TS 122 085 V1

32、3.0.0 (2016-01)63GPP TS 22.085 version 13.0.0 Release 131.2 Description 1.2.1 Service description An ISDN/MSISDN number shall identify each member of a CUG. A CUG shall be defined for one or more basic service groups. CUG members can have additional capabilities that allow them to originate calls ou

33、tside the group, and/or to receive calls from outside the group. CUG members can have additional restrictions 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

34、 CUG. Roaming subscribers must have the same CUG facilities on the roamed-to PLMN as on the Home PLMN. When 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 subscrib

35、er may be a member of a maximum of 10 CUGs. 1.2.2 Applicability to telecommunication services The applicability 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 u

36、ser who has subscribed to the CUG Supplementary Service and is one of the users in the group formed by a 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 prefe

37、rential CUG, which can be specified for each basic service group, is the nominated default CUG to be used 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 arrange

38、ment which allows a member of a CUG to receive calls from outside the CUG. Outgoing Access (OA): An arrangement 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 With

39、in A CUG (ICB): An access restriction that prevents a CUG member from receiving calls from other members 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

40、is restricted to a pre-defined group of users. 1.3 Normal procedures with successful outcome 1.3.1 Provision 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. ETSI E

41、TSI TS 122 085 V13.0.0 (2016-01)73GPP TS 22.085 version 13.0.0 Release 13A user may be a member of several CUGs. The service provider defines the number of CUGs, up to the maximum stated in subclause 1.2.1, which can be allocated to an individual subscriber. The user shall choose one of the followin

42、g 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 basic services: - CUG calls only; - CUG with incoming access, i.e. can also receive calls, which are not subject to

43、CUG restrictions; - CUG with outgoing access, i.e. can also make calls, which are not subject to CUG restrictions; - 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 appl

44、ying for each particular CUG: - incoming calls barred within a CUG; - outgoing calls barred within a CUG. 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 reque

45、st that no preferential CUG exists, or that a particular one of her CUGs (or the only one if a single CUG 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 particu

46、lar CUG as a preferential CUG. The subscription options are shown in Annex 1. The CUG indices shall be allocated 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 With

47、drawal of the CUG Supplementary Service, membership of one or more CUGs, will be by the action of the service 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 res

48、ult 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 havin

49、g neither the restriction of incoming calls barred within a CUG, nor the restriction of outgoing calls barred within a CUG can make calls to, and receive calls from, members of those CUGs of which the user is a member. Upon receipt of a call setup attempt to or from a CUG subscriber the network shall check its validity in conjunction with the access capabilities subscribed to. ETSI ETSI TS 122 085 V13.0.0 (2016-01)83GPP TS 22.085 version 13.0.0 Release 13On successful validation of a CUG call setup attempt the network shall attempt to establish the
