ABSTRACT:
A user of a wireless communication service, e.g. a cellular telephone subscriber, can dial directory assistance; and upon request, the operator service system (OSS) will complete a call connection to a station identified in a retrieved directory listing. The switching office of the wireless communication system will forward data to the operator service system and will provide a connection of the call to the operator service system, both via a dedicated trunk. This trunk utilizes Feature Group D signaling. The OSS identifies the particular carrier providing the wireless communication service based on the identification of the dedicated trunk. The operator service system records the request for call completion, any details of the connection to the identified station necessary for billing and the identity of the requesting terminal. All of this data is forwarded to the identified service operator who in turn adds charges for directory assistance and for the call completion to the user's bill for wireless communication services.
