9、section 1) ; - Call forwarding on mobile subscriber busy (CFB) (section 2); - Call forwarding on no reply ( CFNRy) (section 3 ) ; - Call forwarding on mobile subscriber not reachable (CFNRc) (section 4). 0.2 The forwarded-to number As indicated in TS GSM 02.82 the forwarded-to numbers are stored in

10、the international format. The transfer from the HLR to other network entities and storage in the VLR shall also be in the international format. 0.3 Cross-Phase Compatibility For the following supplementary services, a number of changes exist between this specification and the phase 1 specification:

11、- Call forwarding unconditional - Call forwarding on mobile subscriber busy - Call forwarding on no reply - Call forwarding on mobile subscriber not reachable. The main body of this specification assumes that all network entities comply with this version of the service. In each case an additional su

12、b-section (section x.6) defines the additional requirements for when one or more network entities or the MS complies with the phase 1 specifications for the supplementary service procedures.

13、DING UNCONDITIONAL 1.1 Handling of call forwarding unconditional 1.1.1 Registration At the beginning of registration subscription to the basic service, provision of the supplementary service and sufficiency of registration information has to be checked (see figure 1.2). The following information has

14、 to be registered in the network: 1. the forwarded-to number (possibly including a sub-address); 2. information as to whether all calls or all calls of a specific basic service group should be forwarded. The basic service uroup code If the registration request received by the HLR does not contain an

15、y basic service group code, the registration shall be performed for all subscribed basic service groups for which CFU is provided, see figure 1.2. The forwarded-to number If the forwarded-to number is a number in the HPLMN country, it may be entered by the served mobile subscriber in three different

16、 formats, independent of his actual location, according to the schemes : 1. national (significant) number; 2. (trunk) prefix plus national (significant) number; 3. international prefix, country code, national (significant) The received number may have to be converted to an international number befor

17、e further processing (see figure 1.2). number. The network may also validate the forwarded-to number before accepting the call forwarding registration request. Sumlementarv Service interaction Possible interaction situations between CFU and other call forwarding and barring supplementary services mu

18、st then be checked. This is described in figure 1.2. Also see technical specifications GSM 02.04 and 02.82. For interaction between CFU and other supplementary services (ie not call barring or call forwarding services), the reader is referred to the respective technical specification for those suppl

19、ementary services. Notifications to the subscriber When the mobile subscriber registers CFU, the network shall attempt to register and activate the service. The network will return notification of acceptance of the request. This notification will include the forwarded-to number and possibly the basi

20、c service group code to which CFU is registered. Page 7 GSM 03.82 - version 4.5.0 : June 1993 If the system cannot accept a registration request, the network sends a notification that CFU registration was not successful to the served mobile subscriber. The information flow for registration of CFU is

The SDL diagram in figure 1.8 shows the function to be performed in the HLR in order to deal with the possible

24、 interactions between CFU and the conditional call forwarding services. The Basic Service Group Code The CFU deactivation request may specify a basic service group for which deactivation is required. If the deactivation request received by the HLR doesnt contain any basic service group code, the dea

25、ctivation request shall apply to all basic services for which CFU is active, see figure 1.8. If the deactivation request received by the HLR contains a basic service group code, only information related to the specified basic service group(s) is affected. Note that according to TS GSM 02.04, a reque
