Abstract

A two way communications path is established between a pager device and a paging service provider. The pager device generates a control command for the paging service provider, converts the control command into signals recognizable by a telephone network, and transmits the signals to the paging service provider over the telephone network. The paging service provider receives the signals from the pager device over the telephone network, generates one or more messages for the pager device in response to these signals, and sends the message(s) to the pager device over a wireless paging network. The pager device receives the message(s) over the wireless paging network.

Claims

1. A method of establishing two way communications between a pager device and a paging service provider, said method comprising the steps of:

in said pager device,

generating control command signals for said paging service provider, wherein said control command signals are any signals that alter the behaviour of said paging service provider by causing said paging service provider to generate and send a message to said pager device in response to said control command signals;

transmitting said control command signals to said paging service provider over said telephone network;

in said paging service provider,

receiving said control command signals from said pager device over said telephone network;

generating said message for said pager device in response to said control command signals received from said pager device over said telephone network;

sending said message to said pager device over a wireless paging network; and

in said pager device,

receiving said message from said paging service provider over said wireless paging network.

2. The method of claim 1, wherein said control command signals generated by said pager device is an encryption key, said method further comprising the steps of:

in said paging service provider,

encrypting said message generated in said generating a message step using said encryption key prior to sending said message to said pager device in said sending step; and

in said pager device,

unencrypting said message received from said paging service provider using said encryption key.

3. The method of claim 2, further comprising the steps of:

in said pager device,

taking a phone line connected to said telephone network off hook; and

dialing a phone number associated with said paging service provider.

4. The method of claim 2, wherein said control command signals are a series of DTMF tones, said transmitting step further comprises the step of:

playing said series of DTMF tones through a speaker into a telephone receiver connected to a telephone network connected with said paging service provider.

5. The method of claim 2, further comprising the step of:

displaying said message unencrypted by said unencrypting step.

6. The method of claim 1, further comprising the steps of:

in said pager device,

taking a phone line connected to said telephone network off hook; and

dialing a phone number associated with said paging service provider.

7. The method of claim 1, wherein said control command signals are a series of DTMF tones, said transmitting step further comprises the step of:

playing said series of DTMF tones through a speaker into a telephone receiver connected to a telephone network connected with said paging service provider.

8. The method of claim 1, further comprising the step of:

in said pager device,

displaying said message received from said paging service provider in said receiving step on a display.

9. The method of claim 1, further comprising the steps of:

in said service provider,

generating a plurality of messages for said pager device in response to said control command signals received from said pager device over said telephone network;

sending said plurality of messages to said pager device over a wireless paging network; and

in said pager device,

receiving said plurality of messages from said paging service provider over said wireless paging network.

10. A pager device, comprising:

means for generating control command signals for a paging service provider, wherein said control command signals are any signals that alter the behaviour of said paging service provider by causing said paging service provider to generate and send a message to said pager device in response to said control command signals;

said control command signals being recognizable by a telephone network;

means for transmitting said control command signals to said paging service provider over said telephone network; and

means for receiving said message from said paging service provider over a wireless paging network, said message sent in response to said control command signals sent to said paging service provider over said telephone network.

11. The pager device of claim 10, wherein said control command signals generated by said pager device is an encryption key.

12. The pager device of claim 11, further comprising:

means for unencrypting said message received from said paging service provider using said encryption key.

13. A paging service provider for communicating with a pager device, comprising:

means for receiving control command signals from said pager device over said telephone network, wherein said control command signals are any signals that alter the behaviour of said paging service provider by causing said paging service provider to generate and send a message to said pager device in response to said control command signals;

means for generating said message for said pager device in response to said control command signals received from said pager device over said telephone network; and

means for sending said message to said pager device over a wireless paging network.

14. The paging service provider of claim 13, wherein said control command signals generated by said pager device is an encryption key.

15. The paging service provider of claim 14, further comprising:

means for encrypting said message generated by said generating means using said encryption key prior to sending said message to said pager device with said sending means.
