Digital cellular telecommunications system (Phase 2+); Universal Mobile Telecommunications System (UMTS); Closed User Group (CUG) supplementary service; Stage 3 (V10.0.0; 3GPP TS 24.085 version 10.0.0 Release 10)
This Technical Specification (TS) for Mobile communications specifies the procedures used at the radio interface (reference point Um as defined in 3GPP TS 24.002) for normal operation@ registration@ erasure@ activation@ deactivation@ invocation and interrogation of community of interest supplementary 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 3GPP TS 24.010@ the general aspects of the specification of supplementary services at the layer 3 radio interface are given. 3GPP TS 24.080 specifies the formats coding for the supplementary services. Definitions and descriptions of supplementary services are given in 3GPP TS 22.004 and 3GPP TS 22.08x and 3GPP TS 22.09x-series. 3GPP TS 22.085 is related to the community of interest supplementary services. Technical realization of supplementary services is described in technical specifications 3GPP TS 23.011 and 3GPP TS TS 23.08x and 3GPP TS 23.09x-series. 3GPP TS 23.085 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 interface are defined in 3GPP TS 24.007 and 3GPP TS 24.008. Signalling interworking for supplementary services between 3GPP TS 29.002 and 3GPP TS 24.008 and between 3GPP TS 29.002 and 3GPP TS 24.080 is defined in 3GPP TS 29.011. The following supplementary services belong to the community of interest supplementary services and are described in this TS: - Closed User Group (CUG) clause 1.
