This TS specifies the stage three Protocol Description of the Advice Of Charge (AOC) service, based on stage 1 and 2 of the ISDN Supplementary Service Advice Of Charge for all calls (permanent mode). It provides the protocol details in the IP Multimedia (IM) Core Network (CN) subsystem based on the Session Initiation Protocol (SIP) and the Session Description Protocol (SDP). Three AOC services exist:
  • Charging information at communication set-up time (AOC-S)
    The AOC-S service enables a user to receive information about the charging rates at communication set-up time and also to receive further information during the communication if there is a change of charging rates.
  • Charging information during the communication (AOC-D)
    The AOC-D service enables a user to receive information on the recorded charges for a communication during the active phase of the communication.
  • Charging information at the end of the communication (AOC-E)
    The AOC-E service enables a user to receive information on the recorded charges for a communication when the communication is terminated.
