28、 Scope The present document defines the stage 1 description of the call waiting supplementary service (SS-CW) for the Terrestrial Trunked Radio (TETRA) as provided by European operators. The stage 1 description is an overall service description from the user point of view but does not deal with the
29、details of the human interface itself (see ITU-T Recommendation I.130 1). SS-CW permits a called user to acknowledge an incoming individual call while he is already busy. Subsequently that user shall have the choice to accept, reject or ignore that incoming call. The present document specifies the s
30、ervice description of the supplementary service and the procedures to be expected with successful and unsuccessful outcomes. In addition the present document specifies the interactions with other TETRA supplementary services and inter-working considerations. Charging principles are outside the scope
31、 of the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a sp
32、ecific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.

Subsequently that user shall have the choice to accept, reject or ignore the waiting call. 4.1.2 Qualifications on applicability to telecommunic
44、ation services This supplementary service shall be applicable to all circuit mode individual teleservices and bearer services. 4.2 Procedures 4.2.1 Provision/withdrawal The provision of SS-CW shall be on a per individual subscriber basis, or as a network option general for all (TETRA) individual sub
45、scribers. The corresponding subscriptions shall be valid for all basic services for which SS-CW applies (see clause 4.1.2). The supplementary service shall be withdrawn by the service provider: - for administrative purposes; or - at the request of the served user, if individually provided. No specif

NOTE 1: In ISDN, the case just addressed (where the network cannot present a new additional call when the called user is busy) is one of those corresponding to the situation defined as “Network Determined User Busy“ (NDUB). When the served user is offered such incoming individual call (from user C) while being busy, he shall be able to invoke SS-CW. He sha
