36、 2004 Date of withdrawal of any conflicting National Standard (dow): 31 March 2004 Introduction Supplementary service specifications are produced in three stages, according to the method described in ITU-T Recommendation I.210 2. The present document contains the stage 2 specifications of SS-CFU, SS
37、-CFB, SS-CFNRy and SS-CFNRc. The stage 2 specification identifies the functional entities involved in the supplementary services and the information flows between them. The present document is based on the latest published text of ECMA-173 1. Additions/changes to ECMA-173 1 have been made to take in
38、to account particular TETRA specifics such as group calls and to include situations such as “Not Reachable“ not addressed in ECMA-173 1. NOTE 1: Contrary to ECMA-173 1, the present document does not specify SS-CD (Call Deflection) which is not supported by TETRA. NOTE 2: Contrary to ECMA-173 1, the
39、present document distinguishes between “No reply“ and “Not reachable“ because of the radio nature of the TETRA links. ETSI ETSI EN 300 392-11-4 V1.1.1 (2003-07) 8 1 Scope The present document specifies the Call Forwarding supplementary services: - Call Forwarding Unconditional (SS-CFU); - Call Forwa
40、rding Busy (SS-CFB); - Call Forwarding No Reply (SS-CFNRy); and - Call Forwarding Not Reachable (SS-CFNRc); which are applicable to various basic services supported by TETRA SwMIs. Basic services are specified in EN 300 392-2 3. SS-CFU, SS-CFB, SS-CFNRy and SS-CFNRc are supplementary services which
41、apply during call establishment providing a forwarding of an incoming call to an other destination than the original destination defined by the called (served) user under different conditions (busy, no reply or not reachable respectively) or under no condition (unconditional). The present document i
42、s applicable to circuit mode TETRA tele-services and bearer services only for all supplementary services specified in the present document. The present document applies also for SS-CFU to SDS (Short Data Services). The present document also specifies the SS-CF invocation counter, which limits the nu
43、mber of call forwarding that a call request may encounter during call establishment, e.g. to protect the network against indefinite looping. Man machine interfaces and charging principles are outside the scope of the present document. 2 References The following documents contain provisions which, th
