Abstract

A mobile paging call back system is provided includes a control unit interconnecting a radio pager, a memory, an indicator, a control switch, and an automatic dialer, with the control unit including a logic circuit programmed: (i) to provide verification that valid data representing a telephone number has been received from a radio pager, (ii) to store that data in the memory after verification, (iii) to activate the indicator, after the verification, to provide a system user observable signal indicating that valid data has been received, and (iv) to either transfer the stored data from the memory to the automatic dialer means for use therein to dial a mobile radio telephone or to erase that data from the memory in response to system operator activation of the control switch. Preferably, the system of the subject invention is mounted on the dashboard of a mobile vehicle. A related method is also disclosed.

Claims

1. A mobile paging and radio telephone call back system comprising:

a mobile radio telephone having means for digitally controlling dialing of said telephone in response to control head signals;

radio pager means for receiving radio broadcast paging signals which include data representing a telephone number and for providing as an output data which represents that telephone number;

a mobile power supply coupled to power both said mobile radio telephone and said radio pager means;

a memory;

indicator means for providing a signal to a system operator;

control switch

manual dialer means, coupled to said mobile radio telephone for generating control head signals for digitally controlling dialing of said mobile radio telephone;

control unit means for interconnecting said radio pager means, said memory, said indicator, said control switch and said manual dialer means, said control unit means including;

(a) interface means for converting said data representing said telephone number to corresponding control head signals for use by said mobile telephone; and

(b) a logic circuit;

(i) to provide verification that valid data representing a telephone number has been received from said radio page, (ii) to store said data, after said verification in said memory, (iii) to activate said indicator, after said verificatin, to provide a signal indicating that validated data has been received, and (iv) to either transfer said stored data from said memory to said interface means for use therein to generate said corresponding control head signals to dial said mobile radio telephone or to erase said data from said memory, in response to activation of said control switch; and

means for mounting said system to a mobile vehicle.
