through Internet, particularly to be provided with charged content which is highly
valuable as information.
Among the various billing processes, it is the predominant way to charge a
fixed fee uniformly to all users who registered as members of the web site.
In addition, billing agency web sites, which carry out the billing process of
another web sites, appeared recently. These billing agency web sites carry out the
billing process of the member web sites which requested billing process to the
agency and collect fees from the users uniformly. Then, the agency may determine
the shares for each of the member sites based on the frequency data about the
access of the users.
However, the methods described above have a difficulty to discriminate for
billing a web site which provides information of high quality thereby inducing
many users to access and another web site which does not.

plurality of other web sites according to the users' access time.
According to the present invention, a method for measuring the connection
time of a user terminal to a site via a communication network in a communication
environment comprising said user terminal, said site, and a server which are
connected to each other via said communication network is provided. The method
comprises the steps of transmitting identification information for a user to said
server by said user terminal; transmitting information for a list of registered sites of
said user to said user terminal by referring said identification information for said
user received from said user terminal by said server; recording said information for
the list of registered sites received from said server by the user terminal; informing
said server of the fact that said user terminal accesses said site only if said site is
included in said list of registered sites in response to accessing said site by an
operation of a program for connecting to the site by said user terminal; recording a
time point of access in response to being informed with said fact that said user
terminal accesses said site from said user terminal by said server; determining
whether a new address is within said site in response to changing of the connection
address of said program for connecting to the site by said user terminal; informing
said server of the information for the time point when the address is changed, only
if it is determined that the changed address is not within the site by the user
terminal; and recording the time point of change by referring the information,
received from said user terminal, for the time point when the address is changed by
said server.

[Detailed description of the preferred embodiments]
1. Communication environment in which the present invention is applied
Fig. 1 is a block diagram illustrating the communication environment in
which the method for measuring the connection time to a specific web site through
the Internet according to the present invention is applied.
As shown in Fig. 1, the present invention relates to a method for measuring
the time period in which a user remains connected after accessing to a specific web
site 105 or 107 using a user terminal 111 for each of a plurality of web sites 105
and 107 accessible via internet 101.
In Fig. 1, the communication network is shown as Internet 101, but the idea
of the present invention is not confined to the Internet 101 based on internet
protocol. The Internet 101 used in this specification should be interpreted in a
broad sense as communication network which is able to perform the functions
corresponding to Internet 101 including intranet, local area network, wide area
network, private network, or wireless network, etc.
In addition, it is assumed that the specific sites 105 and 107 are web sites
and the program for connecting to the web site is web browsing program. However,
the concept of the present invention is not limited to be applied to the web sites
and web browsing programs. As apparent from the following description, the idea
of the present invention is applicable to all kinds of access points accessible via
various communication networks and all kinds of access programs used to access
said access points. In this specification, an access point accessible through a
communication network is called as a site. Moreover, data in which the terminal
can download and display after accessing to the site are called as pages. If the site
in the specification is a web site based on World Wide Web protocol, the program
for accessing to the site is a web browsing program and the page is a web page. It
is considered that the site in the specification is a web site as an example.
A server 121 for measuring the connection time of a user to a specific web
site and managing such data is needed to implement the idea of the present
invention. An administration program is executed on the server 121. It is
preferable that the server 121 is equipped with a user database 123 for recording
information for the user registered to the server and a web site database 125 for
recording information for the web site registered to the server.
According to a preferred embodiment of the present invention, a user
preferably performs a registration process after accessing to the server 121.
Information for the user is recorded to the user database 123 of the server 121
through the registration process. The user database stores the member web sites list
in which the user registered, and the starting and closing time points of access for
each of the member web sites for each of the users registered to the server 121.
An agent program and/or web browser plug-in program provided from the
server 121 via communication network 101 or any other way is preferably
executed on the user terminal 111.
Fig. 3 shows an instruction system with the operating system (OS) and web
browser program when the agent program and web browser plug-in program
according to the present invention are executed on the user terminal 111. As
illustrated in Fig. 3, the web browser program 303 for browsing internet web sites
is executed on the operating system 301 for interfacing to the driving and I/O
devices of the user terminal 111. Moreover, it is preferable that the agent program
305 is executed under the control of the operating system 301. The web browser
plug-in program is preferably executed corresponding to the web browser program
303 under the control of the web browser program 303.
It is preferable that the agent program 305 is executed on the terminal 111
under the control of the operating system (OS) of the user terminal 111,
communicates with the administration program of the server 121, and measures the
connection time of the user terminal 111 to the specific web site 105. The user may
download the agent program according to the present invention from the server
121 after or with the registration. The user may download the plug-in program 307
operating with the web browser with the agent program 305 from the server 121.
The agent program 305 and web browser plug-in program 307 can be
installed and executed on the user terminal 111 customized to the type of the
computer and the operating system (OS) of the user terminal 111.
According to a preferred embodiment, the agent program 305 is executed
standby mode under the control of the operating system (OS) or started with the
opening of the web-browsing program for accessing to the web sites. The web
browser plug-in program is executed with the operation of the web browser.
It is preferable that the web site, which wants to be provided with the
connection time measurement service, registers to the server. The information for
the web site is recorded to the web site database 125 of the server 121 via the
registration process.
2. Process for measuring connection time to the web site according to the
present invention
Fig. 2 is a time-series shows the process of the method for measuring the
connection time of a user using a terminal 111 to a specific web site 105 according
to a preferred embodiment of the present invention. Now, the process of measuring
the connection time of a user to a specific web site, operation of the agent program
and plug-in program installed to the user terminal, and the communication process
between the agent program and the administration program of the server are
described by referring Fig. 2. In the following description, it is assumed that the
user completed the user registration process to the server and the specific web site
also completed the web site registration.
Start and initialization of the web browser
First, the user starts the web browser program installed on the terminal 111
(201). The agent program is preferably started simultaneously with the web
browser program or is executing in stand-by mode under the control of the
operating system before the start of the web browser program on the terminal 111.
The user terminal 111 preferably stores the identification information to identify
the user. The identification information of the user is stored as a form of resource
file, and it can be read and transmitted if only the authentication process of the
agent program completes the authentication for the user.
If the agent program starts, the agent program accesses to the server 121
simultaneously with or after the start, and transmits the identification information
of the user who executes the web browser program to the server 121 (203). The
server 121 reads the information for the user corresponding to the identification
information from the user database 123 by referring the received identification
information. Then, the server 121 extracts the member web sites list in which the
user registered, and transmits the list to the user terminal 111 (205).
According to the present invention, the agent program and the server 121
communicates to each other and determines the starting and closing time points of
access to measure the connection time of the user terminal 111 to the specific web
site. To do this, it is preferable that the agent program and the server synchronize
each of the system clocks. According to an embodiment of the present invention,
the agent program transfers the information for the current time, which is set
according to the clock of agent program itself or the system clock of the terminal
111 on which the agent program is executed, to the server 121. Then, the server
121 receives the information for the current time of the agent program, compares it
to the current time of the server 121, and records the information for the time
difference. The server calculates and records the time difference between the user
terminal and the server based on the information for the current time of the user
terminal 111 received from the user terminal 111 and the current time of the server
based on the system clock of the server 121. The server can calculate the absolute
connection time based on the information for the time difference between the
server 121 and the agent program which has already recorded after receiving the
starting and closing time points of access from the agent program.
The agent program remains the status that can refer the member web sites
list during the web browser is executing. Moreover, the web browser plug-in
program watches the web sites to which the web browser connects and transmits
the information thereof to the agent program. The agent program determines if the
connected web site is a registered web site to the member web sites list or not from
the information for the web site received from the web browser plug-in program.
Connection to the specific web site
The user connects to a specific web site 105 among the web sites registered
to the web sites list using web browser (207).
User authentication
The web site requests user authentication to the server in response to the
access request from the web browser on the user terminal 111 (209). According to
an embodiment of the present invention, the user login process to the web site 105
may be performed on the server 121. According to another embodiment of the
present invention, the user login processes to the web sites 105 and 107 registered
to the server may be performed on the server 121 collectively. This is called as
one-pass method. It will be described later in detail.
Then, the server 121 performs the user authentication process via web
browser (211). The web browser may display the user authentication page
administrated by the server by opening another window or may use the same
window. The user transfers the information needed for the user authentication via
web browser to the server 121 (213).
The server 121 determines whether the user is a valid member by referring
the member list of the corresponding web site recorded on the web site database
125 after receiving the information for the user authentication (215).
Record the starting time point of access
If it is determined that the web site 105 which requested user authentication
is a member web site in which the user registered in advance according to the
result of the user authentication, the starting time point is recorded to the server
121 considering that the user starts access to the corresponding member web site
via web browser.
There are various methods to determine the starting time point of access in
the range of the present invention.
According to an embodiment, the web site 105 informs the server 121 of
the very first accessing time point of the user, the server records it as the starting
time point of access. More specifically, the time point when the web browsing
program attempts to connect to the address included in the web site 105 and the
web page corresponding to the address is started to display on the display window
administrated by the web browsing program may be the starting time point of
access.
According to another embodiment, the server 121 records the time point
when the web browser is allowed to access to the contents of the specific web site
105 after the user authentication is completed upon request of the user
authentication from the web site 105. More particularly, the server 121 performs
further step of performing user authentication in response to the user authentication
request from the web site 105. The server 121 records the time point when the user
authentication process of the accessed user to the web site 105 is completed as the
starting time point of the access.
Record the closing time point of access
If the user closes the connection to the specific web site 105 using web
browser, the closing time point is recorded on the server 121.
The process of recording the closing time point of access is as follows. The
web browser plug-in program watches the connection status of the web browser
and transmits the change of the address to the agent program whenever the address
changes in the web browser. The agent program determines whether the changed
address is within the member web site at that time the access is started when the
address of the connected web site of the web browser. If the changed address is not
within the member site, the agent program determines that the access is closed
(217). Then, the agent program informs the server 121 of the time point
determining that the access is closed (219), and the server 121 receives and records
it to the user database 123.
The starting and closing time points of access to the specific web site for
the user are recorded on the member sites list of the server through the successive
processes described before.
Calculation of the connection time
The server accumulates the starting and closing time points of access to the
specific web site 105 for the terminal 111 for each of the member web sites
through the successive processes described before.
In the above embodiment, that is, in the case that the starting time point of
access is determined depending on the system clock of the server 121 and the
closing time point of access is determined depending on the system clock of the
terminal 111, the local time difference between the server 121 and the terminal 111
should be reflected to the calculation of the connection time. That is, according to
an embodiment of the present invention, the server 121 performs a further step of
calculating and recording the time difference between the user terminal 111 and
the server 121 based on the information for the current time of the server based on
the system clock of the server and the information for the current time of the user
terminal 111 received from the user terminal 111. Then, the server calculates the
connection time of the terminal 111 to the specific web site using the starting and
closing time point of access and the time difference.
3. Modified embodiment of the present invention
According to another embodiment of the present invention, a method for
measuring connection time using the exclusive program when the user accesses to
the specific web site using a separate exclusive program other than the web
browser is provided. Operation and processes of this embodiment are similar to
those of the embodiment described above, however, it is preferable that the other
means corresponding to the web browser plug-in program other than that is
provided. Now, the means for performing the functions of the web browser plug-in
program is described in detail.
According to an embodiment of the present invention, a resource program,
which is able to watch the start of the exclusive program under the control of the
operating system 301, may be used. Such resource file is preferably recorded on
the terminal as a file which can be referred during the operating system is
executing. Moreover, the resource file has a function activated with the start of the
program linked to the resource file. Therefore, the agent program may perceive
the start of the exclusive program linked to the resource file by monitoring the
activation of the resource file.
For example, the case that the Windows series operating system developed
by the Microsoft is installed and executed on the computer is described as an
example. A resource file watching the start of the program having function for
accessing to a specific web site and the access to the specific web site under the
control of the operating system, for example, a resource file whose name is
sgared.dll may be recorded on the terminal.
According to another embodiments of the present invention, it is possible
that the server 121 and the agent program 111 carry out as proxy the login and
authentication processes to the web site within the registered web sites collectively.
That is, if the server 121 and the agent program 111 perform the login and
authentication processes of the user once, additional login and authentication
processes to the web site registered to the server 121 among the web site in which
the user registered becomes needless. Such function may be performed by the
agent program described above with the method for measuring connection time to
the web site described above.
[Industrial applicability]
According to the present invention, reasonable billing method for the user
access is provided to a plurality of web sites.
More specifically, it is possible to measure the connection period and the
accessing time point for each of the users as well as the accessing frequencies.
Eventually, it is possible to re-process the information for the users' accessing
practice and frequency to be more valuable based on such information.
