Abstract: A mobile station issues a Call Origination signal. The mobile radiotelephone that has the capability of inserting data content within the dialed digits field of the conventional Call Origination signal. In response to receiving the Call Origination signal, the MSC determines that this mobile station is associated with a "foreign" gateway and issues an Origination Request message to a visitor location register system ("VLR"). The MSC issues a Origination Request message rather than a Qualification Request message because of the prior setting of one or more appropriate call processing trigger(s) at the switch. The MSC/VLR forwards the Origination Request message to the distant gateway or home location register ("HLR") associated with the identified mobile station. The HLR issues an Origination Request RETURN RESULT with the Authorization Denied parameter.
