Methods and apparatus for use in a wireless communication device for
re-establishing communications with a wireless communication network are
described. In one illustrative technique, a data connection is maintained
with the wireless network for communicating data with use of data
connection parameters (e.g. an encryption parameter). In response to a
communication failure, the wireless device attempts to establish a new
data connection with the wireless network. To do this, the wireless
device sends a message to the wireless network which causes the data
connection parameters to be reset. Preferably, the message is a
disconnect frame. After the message is sent, the wireless device sends an
attach request to the wireless network. Thereafter, the wireless device
communicates data over the new data connection with use of new data
connection parameters.
