Methods and apparatus for use in reestablishing a data connection with a
wireless communication network are described. Initially, a wireless
communication device maintains a data connection with a wireless
communication network. During an out-of-coverage condition with the
network, the wireless device is powered off. This causes the wireless
device to reset its parameters associated with the data connection, but
the wireless network will fail to disconnect since the wireless device is
out-of-coverage. After being powered back on and regaining network
coverage, the wireless device transmits a message to the network which
causes one or more network parameters associated with the data connection
to be reset. Subsequently, the wireless device transmits one or more
additional messages to the network for reestablishing the data
connection. In the preferred embodiment, the data connection is a Packet
Data Protocol (PDP) context with a General Packet Radio Service (GPRS)
attachment, the message is a disconnect frame, and the one or more
additional messages include a General Packet Radio Service (GPRS) attach
request. Advantageously, a data connection is substantially seamlessly
maintained for the wireless device despite network connection
complexities.
