28、produced in three stages, according to the method described in ITU-T Recommendation I.210 2. The present document contains the stage 1 specifications of SS-CFU, SS-CFB, SS-CFNRy and SS-CFNRc. The stage 1 descriptions specify the supplementary services as seen by users of networks. The first edition
29、of the present document was presented as a delta document to the first edition of ECMA-173 1. The second edition was redrafted based on the latest published text of ECMA-173 1 as a self contained document so as to be more readable. Additions compared to ECMA-173 1 were made to take into account part
30、icular TETRA specifics such as group calls and to include user requirements and situations 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 presently supported by TETRA. NOTE 2: Contrary to ECMA-173 1, distinction
31、 is needed in the TETRA environment between “no reply“ and “not reachable“ because of the radio nature of the TETRA links. The distinction between the two services is that in the case of SS-CFNRy, the calling user obtains an ALERT signal while in the case of SS-CFNRc, the calling user does not obtai
32、n any signal. The present document is updated to take into account improvements to the protocol in stage 3. ETSI ETSI EN 300 392-10-4 V1.3.1 (2003-09) 8 1 Scope The present document specifies the supplementary services Call Forwarding Unconditional (CFU), Call Forwarding Busy (CFB), Call Forwarding
33、on No Reply (CFNRy) and Call Forwarding on Not Reachable (CFNRc) which are applicable to various basic services supported by TETRA SwMIs. Basic services are specified in EN 300 392-2 4. SS-CFU, SS-CFB, SS-CFNRy and SS-CFNRc are supplementary services which apply during call establishment providing a
34、 forwarding of an incoming call to an other destination than the original destination defined by the calling user under different conditions (busy, no reply or not reachable) or under no condition (unconditional). The present document is applicable to circuit mode TETRA V+D tele-services and bearer
35、services. The present document is also applicable to TETRA Short Data Service (SDS), but limited to the supplementary service Call Forwarding Unconditional (CFU). Man machine interfaces and charging principles are outside the scope of the present document. The present document specifies also the SS-
36、CF invocation counter, which is applicable to various basic services supported by TETRA networks. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

42、terms and definitions apply: Additional Network Feature (ANF): capability, over and above that of a basic service, provided by a SwMI, but not directly to a SwMI user authorized user: user who is responsible for the definition, activation and deactivation of the service NOTE: The authorized user may
43、 also interrogate the service. busy: TETRA destination is considered to be busy if either a “network determined user busy“ or a “user determined user busy“ condition exists call, basic call: instance of the use of a basic service connected number: number of the user that answers (user C) forwarded-t
44、o number: number to which a call is forwarded forwarded-to user: user to which a call is forwarded forwarding: redirection of a call, on behalf of a called user and prior to connect, to a number different from the number of that called user forwarding cause: contains the reason for the forwarding: C
45、FU, CFB, CFNRy, CFNRc forwarding number: number of the served user forwarding user: user for which the call forwarding is invoked; it may be the called user first and then any of the successive forwarded-to users (see also last forwarding user) forward switching: network routeing algorithm which per
46、forms the forwarding by joining together the first connection from user As node to user Bs node and a second, new connection from user Bs node to user Cs node last forwarding user: served user from the point of view of the forwarded-to user for a particular stage of call forwarding NOTE: In the case
47、 of a call subject to a single stage of call forwarding, user B is the last forwarding user from the point of view of user C. In the case of a call subject to multiple stages of call forwarding, user B1 is the last forwarding user from the point of view of user B2, user B2 is the last forwarding use
48、r from the point of view of user B3, etc. The served user for the final stage of call forwarding is the last forwarding user from the point of view of user C. Mobile Station (MS): physical grouping that contains all of the mobile equipment that is used to obtain TETRA services. By definition, a mobi
49、le station contains at least one Mobile Radio Stack (MRS) original called number: number of user B (in case of multiple call forwarding user B1) original called user: first served user of a call which is subject to one or more stages of call forwarding, i.e. user B or B1 partial re-routeing: network routeing algorithm which performs the call forwarding by replacing a particular part of the connection from user As node to user Bs node by another connection from user As node to user Cs node SDS message: status or any type of SDS messa
