13、pecification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS defines the stage 1 of Call Deflection (CD) which enables the served mobile subscriber to respond to an incoming call offered by the
14、 network by requesting redirection of this call to another number specified in the response within the digital cellular telecommunications system (Phase 2/Phase 2+). GTS are produced by TC-SMG to enable the GSM Phase 2+ specifications to become publicly available, prior to submission for the formal
15、ETSI standards approval procedure to become European Telecommunications Standards (ETS). This ensures the earliest possible access to GSM Phase 2+ specifications for all Manufacturers, Network operators and implementors of the Global System for Mobile communications. The contents of this GTS are sub
16、ject to continuing work within TC-SMG and may change following formal TC-SMG approval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in version number as follows: Version 5.x.y where: y the third digit is
17、incremented when editorial only changes have been incorporated in the specification; x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. Reference is made within this GTS to GSM-TSs (note). NOTE: TC-SMG has produced documents which
18、 give the technical specifications for the implementation of the digital cellular telecommunications system. Historically, these documents have been identified as GSM Technical Specifications (GSM-TSs). These TSs may have subsequently become I-ETSs (Phase l), or ETSs/ETSI Technical Reports (ETRs) (P
19、hase 2). TC-SMG has also produced ETSI GSM TSs which give the technical specifications for the implementation of Phase 2+ enhancements of the digital cellular telecommunications system. These version 5.x.x GSM Technical Specifications may be referred to as GTSs. ETSI GSM*02=72 96 II 3400855 0330592

21、nother number specified in the response. The CD supplementary service can only be invoked before the connection is established by the served mobile subscriber, .e. in response to the offered call, or during the period that the served subscriber is being informed of the call. The served subscribers a
22、bility to originate calls is unaffected by the CD supplementary service. 2 Normative references This specification incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are list
23、ed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this specification only when incorporated in it by the amendment or revision.

28、ection Page 8 GSM 02.72 Version 5.0.0: July 1996 4 Description 4.1 General Description The CD Supplementary Service enables the served mobile subscriber to respond to an incoming call offered by the network by requesting redirection of this call to another number specified in the response. The CD su
29、pplementary service can only be invoked before the connection is established by the served mobile subscriber, .e. in response to the offered call during the period that the served subscriber is being informed of the call. The served subscribers ability to originate calls is unaffected by the CD supp
30、lementary service. A maximum number of diversions is permitted for each call with an upper limit of five diversions. When counting the number of diversions, all types of diversions are included. As an network operator option the maximum number of diversions shall be in the range of one to five diver
31、sions per call. If the limit of successive diversions of a call is already reached an unsuccessful call setup indication is sent backward to the network originating the call. The invocation of Call Deflection can either be an automatic response from the mobile station to the offered call (use pre-pr
32、ogrammed information) or may be the result of an action by the served Subscriber. The mobile station related procedures to pre-program and display the deflected40 number is out of the scope of this specification. If the CD service is provisioned and there is no service violation, the request will be
33、 accepted, the connection to the served mobile station will be released (with an appropriate notification) and a call towards the deflection-to subscriber will be established. 4.2 Applicability to telecommunication services The applicability of this supplementary service is defined in GSM 02.04 (ETS
34、 300 503) 2. 5 Normal Procedures with successful outcome 5.1 Provision The supplementary service will be provisioned for all Basic applicable. The service can be offered with one subscription option. subscribed to. It shall be possible to select only one value. Subscription option: Services subscrib
35、ed to and to which it is The option applies to all Basic services Value Calling subscriber receives notification that her call has been deflected - Yes - NO 5.2 Withdrawal The supplementary service will be withdrawn at the subscribers request or for service provider reasons. 5.3 Registration Not app
36、licable. 5.4 Erasure Not applicable. ETSI GSfl*O2.72 96 = 3400855 0330595 740 Page 9 GSM 02.72 Version 5.0.0: July 1996 5.5 Activation Within the network the service is activated for the whole subscription period. This supplementary service shall be activated by the service provider as a result of p
37、rovision. NOTE: No activation/deactivation procedure is needed at the user-network interface. 5.6 Deactivation This supplementary service shall be deactivated by the service provider as a result of withdrawal. 5.7 Invocation The CD supplementary service shall be invoked by the served mobile subscrib
38、er. There is a standardized MMI required for the invocation of the CD supplementary service by Phase 2+ mobiles. 5.8 Interrogation Not applicable. 5.9 Normal Operation The network offers incoming calls to the served mobile subscriber according to the normal procedure. The served subscriber can respo
39、nd to the incoming call offered normally or by invoking the CD supplementary service with an appropriate message. This appropriate message will contain the call deflection request and the deflected-to number. This deflected-to number may be accompanied by a deflected-to subaddress. Two different cas
40、es of the CD invocation can be distinguished: - The invocation can be either an automatic response from the mobile station to the offered call (using pre-programmed information at the mobile station) or - may be the result of an action by the served subscriber. If the CD supplementary service is inv
41、oked and the served mobile Subscriber has subscribed to the service, the network performs the call deflection towards the indicated deflected-to number and clears the call to the called (served) mobile subscriber with a positive acknowledgement. As a subscription option, the sewed mobile subscriber
42、can request that the subscriber A receives a notification that the call has been deflected. The deflected-to subscriber shall receive an indication that the CD supplementary service has been invoked on the call, .e. that call has been deflected. When multiple diversions occurs the reason for diversi
43、on given to the deflected-to subscriber should indicate the last type of diversion (e.g. the invocation of the CD supplementary service). When calls are diverted once, .e. due to a single invocation of the CD supplementary service, the following information shall be given to subscriber A based on th
44、e value of the served mobile subscribers subscription option “calling subscriber receives notification that the call has been deflected“: - if the value of the subscription option is “no“, then no information shall be sent to subscriber A; - if the value of the subscription option is “yes I, then an
45、 indication that the call is being deflected shall be sent to subscriber A. 5.1 O Charging requirements The deflecting subscriber may be charged for the deflected pari of the call.

46、sful outcome 6.1 Invocation and operation If a mobile subscriber tries to invoke the CD supplementary service while not subscribed to or the network operator cannot provide the CD supplementary service for some other reasons, an indication shall be provided to the mobile subscriber to notify her wit
47、h the reason of failure. Possible causes for rejection include: service not subscribed to; deflected-to number invalid; deflected-to number is barred; use of an operator access prefix; insuff icient information; deflected-to number is a special service code (see note); deflected-to number is served
48、mobile subscribers number; the number of diversions has reached the upper limit; supplementary services incompatibility; no call available for deflection. NOTE: Network operators may prevent a served subscriber from invoking the CD supplementary service when the number specified for the deflected-to
49、 subscriber has special significance, e.g. emergency services, operator services. The identification of such numbers is outside the scope of this standard. If the deflected call cannot be completed to the deflected-to subscriber the network shall clear the call towards the subscriber A and notify the subscriber A of the rejection. 7 Interactions with other supplementary services 7.1 Calling Line Identification Presentation (CLIP) When a call has been deflected and the deflected-to subscriber has been provided with the CLIP supplementary service, the d
