Voice channel control of wireless packet data communications

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.

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.

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

• processing a received 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.
