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.
A method of using a wireless device that includes a baseband processor and an applications processor to maintain a data connection to receive data from a remote service over the data connection between the wireless device and a cellular network, the method comprising:
An apparatus configurable for operation in a wireless device, the apparatus comprising:
A wireless device comprising:
