Electronic devices for receiving pushed data
First Claim
1. A method of using a mobile device to communicate with a cellular network, the mobile device comprising a baseband processor and an applications processor, the method comprising:
- by the applications processor;
providing to the baseband processor a timeout value for sending a keep-alive packet to the cellular network;
providing the keep-alive packet to the baseband processor; and
entering a low-power mode,wherein;
the baseband processor is configured to send the keep-alive packet after the timeout value over a data connection between the mobile device and the cellular network while the applications processor is in the low-power mode, andthe timeout value is based at least in part on a time of at least one previous network interaction between the mobile device and the cellular network.

Abstract
Mobile devices such as cellular telephones are provided that communicate with wireless networks. Cellular telephone network equipment may communicate with a cellular telephone over a data connection. The cellular telephone may have an internet protocol (IP) address that allows data to be provided to the cellular telephone over the data connection. To conserve resources and release unused IP addresses, the cellular telephone network equipment may deactivate inactive data connections after a period of inactivity. A baseband processor within a mobile device may periodically send User Datagram Protocol (UDP) keep-alive packets over the data connection to ensure that the data connection remains active. The keep-alive packets may be directed to a packet sink server or may be associated with a black hole route. An applications processor in the telephone may remain in sleep mode during keep-alive packet transmission to conserve power.

9. A method of using a mobile device to communicate with a cellular network, the mobile device comprising a baseband processor and an applications processor, the method comprising:
-
by the applications processor; sending a first keep-alive packet over a data connection between the mobile device and the cellular network while the applications processor is not in a low-power mode; providing a second keep-alive packet to the baseband processor before entering the low-power mode; and entering the low-power mode, wherein; the baseband processor is configured to send the second keep-alive packet over the data connection between the mobile device and the cellular network while the applications processor is in the low-power mode. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method of using a mobile device to communicate with a cellular network, the mobile device comprising a baseband processor and an applications processor, the method comprising:
-
by the applications processor; providing to the baseband processor a timeout value for a timer for sending a keep-alive packet to the cellular network; providing the keep-alive packet to the baseband processor; and entering a low-power mode, wherein; the baseband processor is configured to send the keep-alive packet after expiration of the timer over a data connection between the mobile device and the cellular network while the applications processor is in the low-power mode, and the timeout value is based at least in part on a time of at least one previous network interaction between the mobile device and the cellular network. - View Dependent Claims (19, 20)
