Private Integrated Services Network (PISN)
- Specification, Functional Model and Information Flows - Advice
of Charge Supplementary Services (AOCSD)
3rd edition (December 2001)
This Standard specifies the Supplementary Services Advice of
Charge (SS-AOC), which are applicable to various basic services
supported by Private Integrated Services Networks (PISN). Basic
services are specified in ECMA-142.
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.
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.
AOC-D enables the user to receive information on the recorded
charges during the active phase of the call.
AOC-E enables the user to receive information on the recorded
charges when the call is terminated.
The provision of charging information to the called user, the
provision of charging information for calls that do not leave
the PISN, and PISN accounting are outside the scope of this Standard.
Charging assumptions which apply to the specification of SS-AOC
in this Standard are contained in annex D.
Service specifications are produced in three stages, according
the method described in ETS 300 387. This Standard contains the
stage 1 and stage 2 specifications of SS-AOC. The stage 1 specifications
(clauses 6, 7, 8) specify the supplementary services as seen by
users of PISNs. The stage 2 specification (clause 9) identifies
the functional entities involved in the supplementary services
and the information flows between them.
