Abstract
Abstract An improved wireless information processing apparatus that is connectable to an appropriate one of the access points prepared by an internet provider even under a mobile environment is disclosed. When a user of this terminal requests connection to the Internet, this terminal extracts a CS-ID from notification information transmitted from a wireless base station and, then, retrieves its own association table to acquire a telephone number of an access point nearest to the current location. Then, this terminal dials-up to the acquired access point to establish an internet connection. As a result, this terminal is allowed to download an electronic mail destined therefor, a Web page (HTML file or the like) stored in a disk of a given Web server and the like. Alternatively, this terminal is allowed to transmit data contained therein (or a file and/or an electronic mail edited on this terminal) to another computer system connected to the Internet, or to upload such data to a disk of a given Web server.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
A wireless information processing terminal which is movable across
a plurality of wireless cells, and executes a wireless data exchange
operation with a wireless base station serving one of said wireless cells
where said terminal currently resides, comprising: communication means for executing a communication with a wireless base
station; means for extracting a base station-ID from data received from a
wireless base station; memory means for storing associations between the base station-IDs
and the nearest access points of a provider; access point retrieving means for accessing said memory means and
retrieving one of the access points associated with a current wireless
base station; and means for attempting to establish a connection to the retrieved
access point.
Claim 2
Dependent Claim
46 words
A wireless information processing terminal as claimed in claim 1
further comprising: display means for displaying processed data and the like; data download means for downloading data through the connected access
point; and display control means for causing said display means to display the
downloaded data.
Claim 3
Dependent Claim
115 words
A wireless information processing terminal as claimed in claim 1 or
claim 2 further comprising: input means for allowing a user to input data and a command; and
writing means for writing a user inputted telephone number of an access
point of a provider into said memory means in association with the base
station-ID of a current wireless base station; wherein said memory means is adapted to store data and a program
and said access point retrieving means is responsive to a user's request
for connecting to an access point, for accessing said memory means and
retrieving the telephone number of an access point associated with the
base station-ID of the current wireless base station.
Claim 4
Dependent Claim
53 words
A wireless information processing terminal as claimed in claim 2
wherein said means for establishing a connection includes means for
dialling to the retrieved access point; said data download means downloads Web data through the dialled access
point; and said display control means causes said display means to display the
downloaded Web data.
Claim 5
Independent Claim
120 words
A method of controlling a wireless information processing terminal
which is movable across a plurality of wireless cells, said terminal
having a table for describing associations between base station-IDs and
the nearest access points of a provider, and executing a wireless data
exchange operation with a wireless base station serving one of said
wireless cells where said terminal currently resides, said method
comprising the steps of: receiving notification information from a wireless base station
serving one of said wireless cells where said terminal currently resides;
extracting a base station-ID from said received notification information;
retrieving said table to acquire one of the access points associated with
the base station-ID; and attempting to establish a connection to the acquired access point.
Claim 6
Dependent Claim
109 words
A method as claimed in claim 5 wherein said terminal has input
means for entering data and said retrieving step retrieves from said
table a record relating to the base station-ID, said method comprising
the steps of: responding to successful finding of said record relating to the
base station-ID in said table for attempting to establish a connection to
the access point described in said record; responding to unsuccessful finding of said record relating to the base
station-ID in said table for prompting a user to enter information about
an access point; and registering a record for associating the entered access point with
the base station-ID into said table.
Claim 7
Dependent Claim
47 words
A method as claimed in claim 5 or 6 wherein said terminal has
display means for displaying data, said method comprising the steps of: subsequent to establishment of the connection, downloading data through
the connected access point; and causing said display means to display the downloaded data.
Claim 8
Dependent Claim
62 words
A method as claimed in claim 7 wherein said retrieving step
retrieves said table to acquire a telephone number of an access point
associated with the base station-ID, said connection step includes
dialling to the acquired telephone number of said access point, said
downloading step downloads Web data through the connected access point,
and said display means displays the downloaded Web data.
Claim 9
Dependent Claim
142 words
A computer readable storage medium for storing in a tangible form a
computer program executable on a wireless information processing terminal
which is movable across a plurality of wireless cells, said terminal
having a table for describing associations between base station-IDs and
the nearest access points of a provider, and executing a wireless data
exchange operation with a wireless base station serving one of said
wireless cells where said terminal currently resides, said computer
program comprising: a routine for receiving notification information from a wireless
base station serving one of said wireless cells where said terminal
currently resides; a routine for extracting a base station-ID from said received
notification information; a routine for retrieving said table to acquire one of the access points
associated with the base station-ID; and a routine for attempting to establish a connection to the acquired access
point.
