VOICE CHANNEL CONTROL OF WIRELESS PACKET DATA COMMUNICATIONS
First Claim
1. A method, comprising:
- establishing a voice call session between a requester unit and a wireless unit, the voice call session established on a wireless voice channel of a telecommunications network;
after the voice call session is established between the requester unit and the wireless unit, transmitting a digital polling message from the requester unit to the wireless unit via the wireless voice channel;
including a payload in the digital polling message, wherein the digital polling message is transmitted in-band over the wireless voice channel separately from an out-of-band control channel, and wherein the payload is encoded as audio frequency signals selected to pass through the wireless voice channel unobstructed by vocoders operating in the telecommunications network; and
in the wireless unit, responsive to the digital polling message, initiating a data session with a target.

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.

6. A method for pulling data from a remote wireless unit, the method comprising:
-
transmitting a digital polling message to the wireless unit; including a target address in the polling message; and in the wireless unit, in response to the polling message, 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. - View Dependent Claims (7, 8, 9, 10)

11. An apparatus, comprising:
-
a processor coupled to a telecommunications network; and a polling requester application executable on the processor for sending a polling message through a wireless voice channel of the telecommunications network, wherein the polling message is represented by audio frequency signals selected to pass through the wireless voice channel unobstructed by vocoders operating in the telecommunications network; wherein the polling message is configured to cause a wireless unit to initiate a data session with a target responsive to recovering the polling message from the voice channel. - View Dependent Claims (12, 13, 14)

15. A machine readable medium encoded with instructions that, if executed, result in:
-
processing a voice call in a wireless unit via a wireless telecommunications network; recovering a request message from the voice call, wherein the request message is encoded as audio frequency signals transmitted in-band in a wireless voice channel of the received voice call, wherein the audio frequency signals are received over the wireless voice channel and separately from an out-of-band control channel; and responsive to the recovered request message, initiating a data session between the wireless unit and a target resource for uploading data using a digital wireless data service. - View Dependent Claims (16, 17, 18, 19, 20)
