Abstract

A method and apparatus providing communications between mobile units and other communications devices, is disclosed wherein, in response to a request to call a mobile unit from an originating communications device, a paging signal is sent via a global communications network and received by a mobile unit. The paging signal contains caller and callee identification codes, which are decoded by the mobile unit. A paging response signal, in the form of a reverse call setup signal, is then transmitted from the mobile unit to the originating communications device. Transmission of the paging signal is preferably stopped when a correspondence condition exists such that the caller and callee identification codes of the paging signal correspond to the caller and caller identification codes of the paging response signal.

Claims

1. A method of paging to initiate a call setup between an originating communications device and a mobile unit, comprising:

receiving a request to call the mobile unit from the originating communications device;

forming a paging signal comprised of a caller identification code and a callee identification code;

storing the paging signal in memory;

continuously transmitting the paging signal;

receiving a paging response signal from the mobile unit, the paging response signal being comprised of a caller identification code and a callee identification code;

comparing the paging signal with the paging response signal; and

terminating the transmitting of the paging signal if a correspondence condition is satisfied such that the caller and the callee identification codes of the paging signal correspond to the callee and the caller identification codes of the paging response signal, respectively.

2. The method of claim 1 further comprising deleting the paging signal from said memory if the correspondence condition is satisfied.

3. The method of claim 2 further comprising billing the originating communications device if the correspondence condition is satisfied.

4. The method of claim 1 further comprising billing the originating communications device if the correspondence condition is satisfied.

5. A method of setting up a call between a communications device and a mobile unit, comprising:

transmitting a paging signal comprised of a callee identification code and a caller identification code;

receiving the paging signal at a mobile unit having an identification code;

determining if the callee identification code corresponds to the identification code of the mobile unit;

if the callee identification code corresponds to the identification code of the mobile unit, forming a reverse call setup signal comprised of a caller identification code and a callee identification code, wherein the caller and callee identification code of the reverse call setup signal correspond to the callee and caller identification code of the paging signal, respectively; and

transmitting the reverse call setup signal automatically if the callee identification code of the paging signal corresponds to the identification code of the mobile unit.

6. A method for setting up calls between mobile units and other communications devices, comprising the steps of:

transmitting a request to call a mobile unit from an originating communications device;

forming a paging signal in response to the request to call comprised of a caller identification code and a callee identification code;

continuously transmitting the paging signal;

receiving the paging signal at the mobile unit;

determining if the callee identification code of the paging signal corresponds to an identification code for the particular mobile unit;

transmitting a reverse call setup signal comprised of a caller identification code and a callee identification code from the mobile unit to the originating communications device if the callee code corresponds to the identification code for the mobile unit, said transmission occurring automatically in response to the mobile unit determining that the callee identification code corresponds to the identification code for the mobile unit.

7. An apparatus for providing communications between a mobile unit and a communications device, comprising:

a memory;

a transmitter;

a receiver; and

a processor having an input and an output and being operatively connected to the transmitter and receiver, the processor;

receiving at its input a request to call a mobile unit from an originating communications device and forming a paging signal comprised of a caller identification code and a callee identification code, storing the paging signal in said memory and sending the paging signal to the transmitter;

sending a first control signal to the transmitter to cause the transmitter to continuously transmit the paging signal;

receiving at its input a paging response signal from the mobile unit through the receiver, the paging response signal comprised of a caller identification code and a callee identification code;

retrieving the paging signal from said memory and comparing the paging signal with the paging response signal; and

sending a second control signal to the transmitter to cause transmission of the paging signal to cease if a correspondence condition is satisfied such that the caller and the callee identification codes of the paging signal correspond to the callee and the caller identification codes of the paging response signal, respectively.

8. The apparatus of claim 7 wherein if the correspondence condition is satisfied, the processor deletes the paging signal from the memory.

9. The apparatus of claim 8 wherein if the correspondence condition is satisfied, the call is billed to the originating communications device.

10. The apparatus of claim 7 wherein if the correspondence condition is satisfied, the call is billed to the originating communications device.

11. A mobile unit for communicating with other communications devices comprising:

a receiver;

a memory;

a processor which;

receives a paging signal comprised of a caller identification code and a callee identification code from the receiver;

retrieves from said memory an identification code of the mobile unit;

determines if the callee identification code corresponds to the identification code of the mobile unit; and

forms a reverse call setup signal comprised of a caller identification code and a callee identification code, wherein the caller identification code and the callee identification code of the reverse call setup signal correspond to the callee identification code and the caller identification code of the paging signal, respectively; and

a transmitter for transmitting the reverse call setup signal, wherein the processor sends the reverse call setup signal automatically to the transmitter upon determining that the callee identification code of the paging signal corresponds to the mobile unit identification code.
