The three AOC supplementary services are: a) Charging information at call set-up time (AOC-S) SS-AOC-S enables the user to receive information about the charging rates at call set-up time and also to receive further information during the call if there is a change of charging rates. b) Charging information during the call (AOC-D) SS-AOC-D enables a user to receive information on the recorded charges for a call during the active phase of the call. c) Charging information at the end of the call (AOC-E) SS-AOC-E enables a user to receive information on the recorded charges for a call when the call is terminated. These three supplementary services are supported across the PISN by charge rate provision, interim charge provision and final charge provision or combinations thereof. NOTE – For example, SS-AOC-D could be supported by charge rate provision, by interim charge provision, or by charge rate provision in conjunction with final charge provision. 6.2 SS-AOC operational requirements 6.2.1 Requirements on the Originating PINX Call establishment procedures for the outgoing side of an inter-PINX link and call release procedures, as specified in ISO/IEC 11572 shall apply. Generic procedures for call-related control of supplementary services, as specified in ISO/IEC 11582 for an End PINX, shall apply. 6.2.2 Requirements on the Terminating PINX Call establishment procedures for the incoming side of an inter-PINX link and call release procedures, as specified in ISO/IEC 11572, shall apply. Generic procedures for call-related control of supplementary services, as specified in ISO/IEC 11582 for an End PINX, shall apply. 6.2.3 Requirements on the Outgoing Gateway PINX Call establishment procedures for the incoming side of an inter-PINX link and call release procedures, as specified in ISO/IEC 11572, shall apply. Generic procedures for call-related control of supplementary services, as specified in ISO/IEC 11582 for an End PINX, shall apply. Generic procedures for the call independent control (connection oriented) of supplementary services, as specified in ISO/IEC 11582 for an Outgoing Gateway PINX, shall apply. 6.2.4 Requirements on a Transit PINX Basic call procedures specified in ISO/IEC 11572 for a Transit PINX shall apply. Generic procedures for call-related control of supplementary services, as specified in ISO/IEC 11582 for a Transit PINX, shall apply. 6.2.5 Additional requirements for a Transferring or Diverting PINX that can receive final charge information for a call resulting from transfer or a diverted call Generic procedures for the call independent control (connection oriented) of supplementary services, as specified in ISO/IEC 11582 for a Terminating PINX, shall apply.
