9 Interworking Considerations
22.0723GPPCall Deflection (CD) service descriptionStage 1TS
Non identified.
Annex A (informative):
Deviations to the ISDN service Call Deflection
1) If the call deflection request of a served subscriber is accepted and CD is invoked ISDN gives two network options:
a) The call to the served user is retained until the network receives an indication that the deflected-to user is informed of the call.
b) First the call is removed from the served subscriber and then the connection to the deflected-to subscriber is established.
PLMNs only provide network option b.
2) The service CD does not provide the subscription option "the served user’s ISDN number can be presented to the deflected-to user" to the served subscriber.
3) The interaction between CD and CCBS in the PLMN is different from the interaction between CD and CCBS in ISDN. The activation of the CCBS supplementary service will not be offered to the calling subscriber if the original call is deflected to a busy user. In ISDN the CCBS request applies to the original called party.
4) The handling of notifications to subscriber A in case of multiple diversion is not described in the way as ISDN this has been done. It is the intention of this service description to retain the same handling as it is used in present call forwarding implementations.
