标准范围

ISO/IEC 15050:2003规定了在专用综合业务网络(PISN)内连接在一起的专用综合业务网络交换机(PINX)之间的Q参考点处支持收费补充业务(SS-AOC)的信令协议。SS-AOC是一组补充业务，它使用户能够接收关于其离开PISN并进入另一网络的呼叫的收费信息。三个AOC补充服务是:呼叫建立时的计费信息(AOC-S):SS-AOC-S使用户能够在呼叫建立时接收关于计费率的信息，并且如果计费率发生变化，还可以在呼叫期间接收进一步的信息。呼叫结束时的计费信息（AOC-E）:SS-AOC-E使用户能够在呼叫终止时接收关于记录的呼叫费用的信息。Q参考点在ISO/IEC 11579-1中定义。

ISO/IEC 15050:2003 specifies the signalling protocol for the support of the Advice Of Charge supplementary services (SS-AOC) at the Q reference point between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN).

SS-AOC is a set of supplementary services which enable a user to receive information about the charging of its calls that leave the PISN and enter another network.

The three AOC supplementary services are:

1. 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.
2. 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.
3. 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.
