Voice channel control of wireless packet data communications
View Patent ↗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.
1. A memory device encoded with instructions that, if executed by a processor, result in:
receiving incoming signaling at a wireless unit;
in response to receiving the incoming signaling at the wireless unit, establishing a remotely initiated connection communicatively coupling the wireless unit and a remote server, the remotely initiated connection initiated by the remote server;
receiving, over the remotely initiated connection, a digital polling message at the wireless unit;
identifying a target address in the digital polling message; and
in response to receiving the digital polling message, transmitting outgoing signaling to the target address to initiate 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 memory device 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 memory device 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 memory device according to claim 3 , wherein the type of data to be transmitted is data indicating a location of the wireless unit.
5. The memory device 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 incoming signaling to a wireless unit to establish an outbound connection thereto, the outbound connection initiated by the transmitter;
the transmitter configured to transmit a digital polling message specifying a target address over the outbound connection; and
the wireless unit configured to transmit outgoing signaling to the target address 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. A method, comprising:
receiving incoming signaling at a wireless unit;
in response to receiving the incoming signaling at the wireless unit, establishing a remotely initiated connection communicatively coupling the wireless unit and a remote server, the remotely initiated connection initiated by the remote server;
receiving, over the remotely initiated connection, a digital polling message at the wireless unit;
identifying a target address in the digital polling message; and
in response to receiving the digital polling message, transmitting outgoing signaling to the target address to initiate 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.
12. The method 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 method 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 method of claim 13 , wherein the type of data to be transmitted is data indicating a location of the wireless unit.
15. The method of claim 11 , wherein the polling message is transmitted in a voice call via a digital wireless telecommunications network.
