This European Standard (EN) specifies the procedures used at the radio interface (reference point Um as defined in TS 24.002) for normal operation, registration, erasure, activation, deactivation, interrogation and network invocation of call offering supplementary services. Provision and withdrawal of supplementary services is an administrative matter between the mobile subscriber and the service provider and cause no signalling on the radio interface.
In 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 and coding for the supplementary services.
Definitions and descriptions of supplementary services are given in TS 22.004 and 3GPP TS 22.08x and 3GPP TS 22.09x series. TS 22.082 is related specially to call offering supplementary services.
Technical realization of supplementary services is described in TS 23.011 and 3GPP TS 23.08x and 3GPP TS 23.09x series. TS 23.082 is related specially to call offering supplementary services.
The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3 radio interface are defined in TS 24.007 and TS 24.008.
The following supplementary services belong to the call offering supplementary services and are described in the present document:
  • Call forwarding unconditional (CFU) (clause 1);
  • Call forwarding on mobile subscriber busy (CFB) (clause 2);
  • Call forwarding on no reply (CFNRy) (clause 3);
  • Call forwarding on mobile subscriber not reachable (CFNRc) (clause 4).

0.2  AbbreviationsWord‑p. 7

Abbreviations used in the present document are listed in TR 21.905.

0.3  Cross phase compatibility

For the following supplementary services, a number of changes exist between the present document and the protocol version 1 specification:
  • Call forwarding unconditional;
  • Call forwarding on mobile subscriber busy;
  • Call forwarding on no reply;
  • Call forwarding on mobile subscriber not reachable.
For these supplementary services, the main body of the present document assumes that all network entities comply with this version of the service. In each case, an additional subclause (subclause x.7) defines the additional requirements for when one or more network entities or the MS complies with the protocol version 1 specifications for the supplementary service procedures.
