Abstract
Abstract In 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
A method of operating a portable communication device
capable of communicating with a remote server via at least first and
second different communication arrangements, CHARACTERIZED BY
the steps of monitoring at least one signal indicative of the environment in
which said device is operating in order to anticipate a change in the
communications arrangement used by said portable communication
device to communicate with said remote server, if a change is determined in said monitoring step to be both
imminent and significant, altering the operation of the portable device by
adjusting at least one parameter affecting signals included in the
application or transport layer protocol used in said device.
Claim 2
Dependent Claim
25 words
The method of claim 1 wherein said portable
communication device includes a laptop or palmtop computer, a personal
digital assistant (PDA), or a cellular telephone.
Claim 3
Dependent Claim
60 words
The method of claim 2 wherein said portable
communication device includes a software controlled processor and at
least first and second communications interfaces associated with said at
least first and second different communication arrangements,
respectively, and wherein said monitoring step is performed in the
network protocol layer of said processor using signals received from said
first and second communications interfaces.
Claim 4
Independent Claim
143 words
A method of managing operation of a portable
communication device having a processor controlled by instructions
contained in a multilayer protocol stack, said protocol stack including at
least an application protocol layer controlling the user level operation of
said device and a communication protocol layer controlling the
transmission of data to said device and the reception of data by said
device, said method CHARACTERIZED BY the steps of determining the likelihood of the occurrence of changes in the rate
at which said portable communication device receives or transmits data
to a remote location, and responsive to said determining step, and substantially
simultaneously with the occurrence of changes in the rate at which said
portable communication device receives or transmits data to a remote
location, altering the operation of said portable communication device by
altering at least one parameter controlling said application protocol layer.
Claim 5
Dependent Claim
30 words
The method defined in claim 4 wherein said device includes
a display for pictorial information, and said altering step includes
changing the characteristics of the image displayed on said display.
Claim 6
Dependent Claim
18 words
The method defined in claim 5 wherein said characteristics
include the size or the resolution of said image.
Claim 7
Dependent Claim
20 words
The method defined in claim 6 wherein said determining
step includes monitoring changes in operation of said communication
protocol layer.
Claim 8
Dependent Claim
38 words
The method defined in claim 4 wherein said device includes
a GPS system, and wherein said determining step includes monitoring
changes in the geographic location of said device as a result of signals
generated by said GPS system.
Claim 9
Dependent Claim
18 words
The method of claim 8 wherein said altering step includes
changing the parameters in said application protocol layer.
Claim 10
Dependent Claim
22 words
The method of claim 9 wherein said determining step
includes monitoring the strength of signals received by or transmitted
from said device.
