Abstract
A combined landline Advanced Intelligent Network (AIN) and Cellular Digital Packet Data (CDPD) system provides the capability of call feature selection using control signals generated by a mobile subscriber. The calling features are specified by the control signals which are sent within the CDPD system from the subscriber station to a CDPD controller or switching entity. Protocol translation takes place so that the control signals from the subscriber station are placed in a form suitable for the CCIS normally used in an AIN. These signals are transferred to convenient AIN switching or control entity and sent to an ISCP where the request for calling features are evaluated and instructions given to other elements of the AIN to provide the requested calling features.
