If the forwarded-to number is a number in the HPLMN country, it may be entered by the served mobile subscriber in three different formats, independent of her actual location, according to the schemes: 1) National (significant

13、) number. 2) National (trunk) prefix plus national (significant) number. 3) International prefix, country code, national (significant) number.

14、 country, it shall be entered by the served mobile subscriber, independent of her actual location, according to the following scheme: - International prefix, country code, national (significant) number. Note: The MMI for entering of international prefix is defined in Recs. GSM 02.30 and 02.07. Princ

15、iples for interaction with the Barrinn of Outqoinq Calls supplementary services.

When Barring of all incoming calls when roaming outside the HPLMN country is active and operative - .e. the served mobile subscriber is roaming outside the HPLMN country, the Conditional Call Forwarding services are not allowed. 3404583 0078053 545 Page 7 GS

19、M 02.82 - version 4.4.2 : June 1993 1 CALL FORWARD1 NG UNCONDITIONAL 1.1 DEFINITION This service permits a called mobile subscriber to have the network send all incoming calls, or just those associated with a specific Basic service group, addressed to the called mobile subscribers directory number t

20、o another directory number. The ability of the served mobile subscriber to originate calls is unaffected. If this service is activated, calls are forwarded no matter what the condition of the termination. 1.2 DESCRIPTION 1.2.1 Descrlptlon The served mobile subscriber can request a different forwarde

21、d-to number for each Basic service group containing a basic service to which she has subscribed. 1.2.2 Appllcablllty to telecommunication services Call forwarding unconditional is applicable to all telecommunication services except Emergency calls and the Short Message Service. 1.2.3 Term In ol ogy

22、A served mobile subscriber is a mobile subscriber of a particular PLMN access who is requesting that calls to her number be forwarded. This subscriber may also be referred to as the forwarding subscriber or the called subscriber. A forwarded-to subscriber is a subscriber to whom the call shall be fo

23、rwarded. 1.3 NORMAL PROCEDURES WITH SUCCESSFUL OUTCOME 1.3.1 Provlslon The supplementary service will be provisioned for all Basic Services subscribed to and to which it is applicable. The service can be offered with one subscription option. The option applies to all Basic services subscribed to. On

Page 8 GSM 02.82 - version 4.4.2 : June 1993 If no Basic Servic

26、e code is inserted by the user this is interpreted as All Basic Services. Registration can take place either by the service provider or with an appropriate control procedure by the subscriber. Verification, where possible, of the forwarded-to number should be accomplished before accepting the call f

27、orwarding request. This verification is done by a simple check of the forwarded-to number to see if the number is within the allowed number range. When the mobile subscriber so registers call forwarding unconditional, the network will return notification of acceptance or rejection of the request. Th

28、is notification will include the forwarded- to number to which call forwarding unconditional is registered. 1.3.4 Erasure A previous registration can be erased in either of three ways: Firstiy, the subscriber can specif ically erase a previous registration with an appropriate control procedure. Seco

29、ndly, the subscriber can register information for call forwarding unconditional for the specific Basic service group to another directory number, thus causing the previous registration of call forwarding unconditional to be overridden. Thirdly, all information is erased as a result of withdrawal of

30、the service. 1.3.5 Activation The user shall be allowed to activate Call Forwarding Unconditional (CFU) by e.g. using the MMI command described in GSM 02.30. This activation request may include information of which Basic Service Group) it shall appiy to. If no such information is included the Activa

31、tion request applies to all Basic Service Groups.

39、. When multiple forwarding occurs the reason for forwarding given to the forwarded-to subscriber should relate to the last forwarding subscriber in the chain. When call forwarding unconditional is active and operative, the ability of the served mobile subscriber to originate calls is not affected. H

40、owever, an indication that the call forwarding service is currently active and operative on a number will be given to the forwarding party each time an outgoing call is made. As a subscription option, the served mobile subscriber can request that the calling subscriber receives a notification that t

41、he call has been forwarded. 1.3.11 interrogation Data request The data request procedure enables the mobile subscriber to obtain information about the data stored in the PLMN. After having requested this procedure the network shall return the following information: - in response to a general data re

42、quest the served mobile subscriber should be given a list of all Basic service groups to which call forwarding unconditional is registered, including information whether or not it is active and operative, and the associated forwarded-to num bers; in response to a specific request concerning one part

47、oup(s). The network is not required to validate information related to the forwarded-to number. 1.4.3 Erasure If the network cannot accept a mobile subscribers request for erasure, cause will be returned to the subscriber, such as: - insufficient information - inconsistent with registration. If the

48、subscriber does not completely specify which call forwarding unconditional request is to be erased, the network will reject the erasure request with appropriate cause.
