CD Call Deflection ETSI ETSI TS 122 072 V15.0.0 (2018-07)73GPP TS 22.072 version 15.0.0 Release 154 Description 4.1 General Description The CD Supplementary Service enables
36、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 supplementary service can only be invoked before the connection is established by the served mobile subscriber, i.e. in respon
37、se 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 supplementary service. A maximum number of diversions is permitted for each call with an upper limit of five diversions. When c
38、ounting 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 diversions per call. If the limit of successive diversions of a call is already reached an unsuccessful call setup indication is
39、 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-programmed information) or may be the result of an action by the served subscriber. The mobile station related procedures to
40、pre-program and display the deflected-to 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 accepted, the connection to the served mobile station will be released (with an appropriate notification) and a call towa
41、rds the deflection-to subscriber will be established. 4.2 Applicability to telecommunication services The applicability of this supplementary service is defined in TS 22.004 2. 5 Normal Procedures with successful outcome 5.1 Provision The supplementary service will be provisioned for all Basic Servi
42、ces subscribed to and to which it is applicable. The service can be offered with several subscription options. Options apply to all Basic services subscribed to. For each subscription option, only one value can be selected. Subscription option: Value Calling subscriber receives notification that her
43、 call has been deflected - Yes - No MSISDN of the served subscriber can be presented to the deflected-to subscriber - Yes - No 5.2 Withdrawal The supplementary service will be withdrawn at the subscribers request or for service provider reasons. 5.3 Registration Not applicable.

44、V15.0.0 (2018-07)83GPP TS 22.072 version 15.0.0 Release 155.4 Erasure Not applicable. 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 provision. NOTE: No activation/deac
45、tivation 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 subscriber by use of a control procedure a
46、s described in TS 22.030 3. 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 respond to the incoming call offered normally or by invoking the CD supplementary service
47、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 cases of the CD invocation can be distinguished: - The invocation can be either an autom
48、atic 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 invoked and the served mobile subscriber has subscribed to the service, the network perf
49、orms 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 served mobile subscriber 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, i.e. that call has been deflected. Depending on the value of the served subscribers subscription option, the deflected-to subscrib
