8、0: December 1996 Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS specifies the procedures used at the radio interfa
9、ce (reference point Um as defined in GSM 04.02) for normal operation, registration, erasure, activation, deactivation, invocation and interrogation of Closed User Group (CUG) supplementary services within the digital cellular telecommunications system. The contents of this GTS are subject to continu
10、ing work within TC-SMG and may change following formal TC-SMG approval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in version number as follows: Version 5.x.y where: y the third digit is incremented whe
11、n editorial only changes have been incorporated in the specification; x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. The specification from which this GTS has been derived was originally based on CEPT documentation, hence the
12、presentation of this GTS may not be entirely in accordance with the ETSVPNE rules.

13、This Global System for Mobile communications Technical Specification (GTS) specifies the procedures used at the radio interface (reference point Um as defined in GSM 04.02) for normal operation, registration, erasure, activation, deactivation, invocation and interrogation of community of interest su
14、pplementary services. The provision and withdrawal of supplementary services is an administrative matter between the mobile subscriber and the service provider and causes no signalling on the radio interface. In GSM 04.10, the general aspects of the specification of supplementary services at the lay
15、er 3 radio interface are given. GSM 04.80 specifies the formats coding for the supplementary services. Definitions and descriptions of supplementary services are given in GSM 02.04 and GSM 02.8 and GSM 02.9-series. GSM 02.85 is related to the community of interest supplementary services. Technical r
16、ealization of supplementary services is described in technical specifications GSM 03.1 1 and GSM 03.8 and 03.9-series. GSM 03.85 is related to the community of interest supplementary services. The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3 radio int
17、erface are defined in GSM 04.07 and GSM 04.08. Signalling interworking for supplementary services between GSM 09.02 and GSM 04.08 and between GSM 09.02 and GSM 04.80 is defined in GSM 09.1 1. The following supplementary services belong to the community of interest supplementary services and are desc

In the case of Implicit invocation, no CUG informati
33、on is provided by the user in the call Set-up request and a default attribute of CUG is invoked. Normal call establishment procedures are followed over the radio interface and no CUG signalling is required. In the case of Explicit CUG invocation, CUG information is provided by the user and is includ
34、ed in the SETUP message using the ForwardCUG-Info operation (see figure 1.1 ). User provided CUG information may consist of any combination of the following parameters: - CUGIndex; - Suppress Preferential CUG indicator; - Suppress OA indicator. NOTE: No more than one of each parameter may be include
35、d per call attempt. MS Network SETUP Facility (Invoke = ForwardCUG-Info (CUG-Index, SuppressPrefCUG, SuppressOA) Figure 1.1 : Transfer of CUG information during CUG call Set-up If the network received a non-zero SS Screening indicator from the calling users mobile station, the network may optionally
36、 indicate to the MS that a CUG has been invoked for a call (see figure 1.2). When a CUG Index is received from the VLR the MSC shall send it immediately to the MS in a FACILITY or CALL PROCEEDING message. If the network did not receive a non-zero SS Screening indicator from the calling users mobile
37、station, it shall not send this notification.

38、96 1.1.1.2 Unsuccessful operation When an attempted CUG call is rejected for CUG related reasons, the mobile station is provided with an indication of the reason for failure. The indication is passed to the calling MS in the first clearing message. The indication may be given in one of two ways: - D
39、iagnostics information in cause value #29 “Facility Rejected“; - A standard call control cause value. Diagnostics are used when the rejection is generated locally (the serving VLR has rejected the call), or if they are provided in a cause value from a remote network node (see figure 1.3). Table 1.1
40、gives the diagnostics information for each potential local rejection case. A CUG rejection from a remote network node is generally indicated using a standard (CUG related) call control cause value contained in an ISUP clearing message. These cause values are passed to the mobile station in the appro
41、priate radio interface clearing message (see figure 1.4). Table 1.2 gives the cause values in each potential remote rejection case. All CUG related call rejection cases are defined in GSM 03.85. Cause values are defined in GSM 04.08 and diagnostics in GSM 04.80. NOTE: Annex A specifies the mapping o
42、f cause values between MAP, ISUP and GSM 04.08 for remotely generated CUG rejections. MS Network DISCONNECT/RELEASE/RELEASE COMPLETE .

48、1.2 Mobile terminated calls If the network received a non-zero SS Screening indicator from the called users mobile station, when a CUG call is terminated by a CUG subscriber the Index associated with the invoked CUG may be passed to the mobile station (see figure 1.5). If the network did not receive a non-zero SS Screening indicator from the called users mobile station, it shall not send this notification. 1.2 Activation, deactivation, interrogation, registration and erasure Activati
