Abstract

A data session with a wireless device ordinarily cannot be initiated from the network side because the wireless device has no predetermined IP or other network address. Methods are disclosed for instead causing the wireless unit to initiate a data session with a target destination, thereby obviating the IP addressing problem. A voice call is first initiated by a requester application to a remote wireless unit. The requester transmits a request message to the remote wireless unit via the wireless voice channel using in-band techniques; preferably including a payload in the polling message that identifies the target destination. In response, the remote wireless unit initiates a packet data session with the target destination.

Claims

1. A machine readable medium encoded with instructions that, if executed by a processor, result in:

receiving a digital polling message at a wireless unit;

identifying a target address in the digital polling message; and

in response to receiving the digital polling message, initiating a wireless network data session with the target address without manual user intervention at the wireless unit, the wireless network data session to be used by a computing device associated with the target address to pull data from the wireless unit over the wireless network data session.

2. The machine readable medium according to claim 1, wherein the polling message includes at least one delivery parameter specifying at least one of a selected wireless network packet data service, a data rate, and a priority parameter.

3. The machine readable medium according to claim 1, wherein the polling message identifies a type of data to be transmitted from the wireless unit to the target address in the wireless network data session.

4. The machine readable medium according to claim 3, wherein the type of data to be transmitted is data indicating a location of the wireless unit.

5. The machine readable medium according to claim 1, wherein the polling message is transmitted in a voice call via a digital wireless telecommunications network.

6. A system, comprising:

a transmitter configured to transmit a digital polling message specifying a target address to a wireless unit; and

the wireless unit configured to initiate a wireless network data session with the target address in response to receiving the digital polling message and without manual user intervention at the wireless unit, the wireless network data session to be used by a computing device associated with the target address to pull data from the wireless unit over the wireless network data session.

7. The system of claim 6, wherein the polling message includes at least one delivery parameter specifying at least one of a selected wireless network packet data service, a data rate, and a priority parameter.

8. The system of claim 6, wherein the polling message identifies a type of data to be transmitted from the wireless unit to the target address in the wireless network data session.

9. The system of claim 8, wherein the type of data to be transmitted is data indicating a location of the wireless unit.

10. The system of claim 6, wherein the polling message is transmitted in a voice call via a digital wireless telecommunications network.

11. An wireless unit, comprising:

means for identifying a target address included in a received digital polling message; and

means for initiating a wireless network data session with the target address in response to receiving the digital polling message and without manual user intervention at the wireless unit, the wireless network data session to be used by a computing device associated with the target address to pull data from the wireless unit over the wireless network data session.

12. The wireless unit of claim 11, wherein the polling message includes at least one delivery parameter specifying at least one of a selected wireless network packet data service, a data rate, and a priority parameter.

13. The wireless unit of claim 11, wherein the polling message identifies a type of data to be transmitted from the wireless unit to the target address in the wireless network data session.

14. The wireless unit of claim 13, wherein the type of data to be transmitted is data indicating a location of the wireless unit.

15. The wireless unit of claim 11, wherein the polling message is transmitted in a voice call via a digital wireless telecommunications network.
