29、 or it shall be possible to activate the supplementary service on a per call basis. The activation on a per call basis shall occur at call request. 3.2.2 Invocation and operation The charging information shall be provided by the network when the call is terminated. 3.3 Exceptional procedures 3.3.1 A

30、ctivatioddeactivatiodregistration Not applicable. 3.3.2 Invocation and operation If the charging information related to a call is not available this should be indicated to the served user. 3.4 Alternative procedures None identified. 4 Network capabilities for charging This Recommendation does not co

31、ver charging principles. Future Recommendations in the D-Series are expected to contain that information. It shall be possible to charge the subscriber accurately for the service. 5 Interworking requirements The AOC-E supplementary service shall be supported across the internetwork interface between

32、 ISDNs (i.e. public or private). Recommendation 1.256.2 (03193) 3 6 Interactions with other supplementary services 6.1 Call waiting No impact, i.e. neither supplementary service affects the operation of the other supplementary service. 6.2 Call transfer If a call is transferred and the transferring

33、user is charged for either or both calls, then as a network option, that user shall be informed of the charge at the end of the resulting transferred call. 6.3 Connected line identification presentation No impact, i.e. neither supplementary service affects the operation of the other supplementary se

34、rvice. 6.4 Connected line identification restriction No impact, i.e. neither supplementary service affects the operation of the other supplementary service. 6.5 Calling line identification presentation No impact, i.e. neither supplementary service affects the operation of the other supplementary ser

35、vice. 6.6 Calling line identification restriction No impact, i.e. neither supplementary service affects the operation of the other supplementary service. 6.7 Closed user group No impact, i.e. neither supplementary service affects the operation of the other supplementary service. 6.8 Conference calli

36、ng a) Conference controller 1) Invocation of the conference, add-on supplementary service from the idle state - If the conference controller can activate the AOC-E supplementary service at the same time the conference, add-on supplementary service is invoked. 2) Invocation of the conference, add-on

37、supplementary service from an active call - If the AOC-E supplementary service has been activated for the initial call, then it shall automatically be activated also for the conference. If the AOC-E supplementary service has not been activated for the initial call, then the conference controller can

38、 activate the AOC-E supplementary service at the same time the conference, add-on supplementary service is invoked. - 3) Addition of a call to a conference For calls between the conference controller and potential conferees which are outside the conference call, the normal procedures for the AOC-E s

39、upplementary service shall apply. When a call for which AOC-E supplementary service has been activated, is added to the conference, then charging information shall be given as if the call was terminated at the moment it is added to the conference. NOTE 1 - Further charging resulting from communicati

40、on with the new conferee shall be considered to be part of the charging for the conference. 4 Recommendation 1.256.2 (03193) ITU-T RECMN*I.256. 2C 93 W 4862591 0583841 235 4) Creating a private communication with one of the parties In this case the private communication shall be considered as a new

41、call between the conference controller and the individual party. If the AOC-E supplementary service is active for the conference, it shall in addition be automatically activated for the new call when the private communication is established. 5) Terminating the conference When the conference is termi

42、nated and AOC-E supplementary service had been activated for the conference, then the overall charges for the conference shall be sent to the conference controller. If the conference, add-on supplementary service was invoked from an active call and AOC-E supplementary service was activated for that

43、call, then the charging information shall include charges for the initial call. 6) Other operation on the conference No impact, i.e. neither supplementary service shall affect the operation of the other supplementary service. NOTE 2 - Some networks may not support the AOC-E supplementary service in

44、conjunction with the conference, add-on supplementary service, or may only give partial information, e.g. due to off-line processing of the charges associated to the conference, add-on supplementary service. In this case an indication that the AOC-E supplementary service is not available shall be gi

45、ven on invocation of the conference, add-on supplementary service if the AOC-E supplementary service is activated. b) Conferees No impact, i.e. neither supplementary service shall affect the operation of the other supplementary service. 6.9 Direct dialling-In No impact, i.e. neither supplementary se

46、rvice affects the operation of the other supplementary service. 6.10 Call diversion 6.10.1 Cali forwarding busy - Original calling user: No impact, i.e. neither supplementary service affects the operation of the other supplementary service.
