A method of effectuating a change in the operation of a portable communication device such as a laptop or palmtop computer, a personal digital assistant (PDA), or a cellular telephone. The device can communicate with a remote host or server using one of two or more different communication arrangements. Various signals indicative of the environment in which the device is operating are monitored, to anticipate or predict a change or transition from one communication arrangement to the other. If the change is determined to be both imminent and significant, the operation change is effected substantially simultaneously, by changing parameters in the transport and/or application protocol layer in the device.
