A site management device 8 or the like is connected.

  The mobile phone device 1 includes a position detection function for detecting whether or not the mobile phone device 1 is in the communication area (in the radio wave arrival area) by performing wireless communication with the local base station 2. Whether or not the user is in the premises (in-house) is detected based on whether or not the transmitted radio wave is normally received and acquired. When the mobile phone device 1 is in a premises (in-house communication area) when a public mobile phone line is selected and an arbitrary Web site on the Internet is designated as an access target, the mobile phone device 1 To request site access. In other words, when accessing the site from the premises, the access request is made to the premises server 4.

  The local server 4 has a SIP server function, a database server function, and the like. When a site access request is received from the mobile phone device 1, the site requested to access with reference to the restriction list 9 is restricted in advance. It is determined whether or not the site is a restricted site, and the determination result is transmitted to the requesting mobile phone device 1. In other words, the local server 4 compares the URL of the designated site requested to be accessed from the mobile phone device 1 with each URL registered in the restriction list 9 so that the designated site is a restricted site where access is restricted in advance. The mobile phone device 1 recognizes the determination result transmitted from the local server 4, and, as a result, if it is not a restricted site, the mobile phone device 1 uses the public mobile phone line as a condition. Access to the designated site is permitted, but if it is a restricted site, access to the designated site via a public mobile phone line is prohibited.

  The restriction list 9 is a list (black list) table that lists URL (Uniform Resource Locator) such as harmful sites that are arbitrarily set and registered in advance as access restriction target sites. The content is updated regularly or as needed. In other words, it is set and registered arbitrarily to restrict access to various sites on the Internet, such as adult sites and violent sites, as well as entertainment sites that are not related to company operations. New harmful sites and the like are additionally registered in the restriction list 9 as needed or necessary.

FIG. 2 is a block diagram showing basic components of the mobile phone device 1.
The CPU 11 is a central processing unit that controls the overall operation of the mobile phone device in accordance with various programs in the storage unit 12.

The non-contact IC unit 22 is used not only as an electronic money payment function but also as a pass for a gate such as a commuter pass, and between an IC card reader / writer (not shown) as an external terminal device. Short-range communication using weak radio waves is performed.

  Next, the operation concept of the cellular phone device in this embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. In other words, in addition to the recording medium, an operation peculiar to this embodiment can be executed by using a program / data supplied externally via a transmission medium.

FIG. 3 is a flowchart showing the operation of the mobile phone device 1 that is started to execute when an arbitrary website on the Internet is accessed.
First, in order to access an arbitrary Web site on the Internet, the CPU 11 of the mobile phone device 1 takes in the input URL and temporarily stores it when the URL is designated (step A1). When this connection button is operated in a waiting state for a connection button (not shown) for selectively connecting a local mobile phone line (wireless LAN line) or a public mobile phone line (step A2), this connection is established. The type of the line selected and designated by operating the button is discriminated (step A3).

  If the local mobile phone line (wireless LAN line) is selected, the process proceeds to step A4, where the site from the local site is determined depending on whether or not the radio wave transmitted from the local base station 2 has been normally received and acquired. It is determined whether or not it is an access, that is, whether or not the campus access is possible (is in the campus). Here, when the user is not on the premises or cannot access the premises even if the user is on the premises (NO in step A4), a message indicating that access is not possible is read, and an inaccessible screen as shown in FIG. 5 is displayed as a guide. However, if local access is possible (YES in step A4), a URL access request is made to the local server 4 (step A6).

FIG. 4 is a flowchart showing the operation of the local server 4 that starts executing in response to a URL access request from the mobile phone device 1.
First, upon receiving a URL access request from the mobile phone device 1, the local server 4 compares the URL of the designated site requested for access with each URL registered in the restriction list 9 (step B1), and this designation. It is checked whether or not a restricted site that matches the site is registered (step B2). Here, when the designated site for which access is requested corresponds to a restricted site, a “restriction response” for indicating that the access is restricted is transmitted to the requesting mobile phone device 1. (Step B3) If the site does not correspond to the restricted site, the request source mobile phone device 1 is connected to the public service network 5 through the private PBX 3 (Step B4).

  Here, when the mobile phone device 1 that has made a URL access request to the local server 4 receives the “restriction response” transmitted from the local server 4 (YES in step A7 in FIG. 3). Then, while prohibiting access to the designated site, a message indicating that the site cannot be accessed is read out and the access inaccessible screen (see FIG. 5) is guided and displayed (step A8). On the other hand, if the designated site is not a restricted site (NO in step A7), it is connected to the Internet via the local server 4 and the ISP management server 7 (step A9). When a website (designated site) on the Internet is accessed via the ISP management server 7, the designated site is downloaded and received (step A10), and the contents of the received site are displayed and output (step A11). . Here, various processes according to operations such as page switching can be executed (step A12), and until the end operation such as closing is performed (step A13), the process according to the operation content is performed.

  On the other hand, when a public mobile phone line is selected by the above connection button operation (step A3), local access is possible depending on whether or not the radio wave transmitted from the local base station 2 has been successfully received and acquired. (Step A14). If the premises access is not possible even if the premises are not present (NO in step A14), the process proceeds to step A18, but if premises access is possible (YES in step A14). Then, a URL access request is made to the local server 4 (step A15). Even in this case, the local server 4 executes the operation in accordance with the flowchart of FIG. 4, and if the designated site requested to be accessed is a restricted site, a “restricted response” for indicating that the access is restricted. ”Is transmitted to the requesting mobile phone device 1, but if it is not a restricted site, the requesting mobile phone device 1 and the public service network 5 are externally connected via the private PBX 3.

  Here, when receiving the “restriction response” from the local server 4 (YES in step A16), the cellular phone device 1 prohibits access to the designated site via the public cellular phone line and accesses it. A message indicating that the access is not allowed is read and an inaccessible screen (see FIG. 5) is guided and displayed (step A17). If the designated site is not a restricted site (NO in step A16), the process proceeds to step A18, and the mobile communication network is connected. It is determined whether or not the site access is from outside the company (public access is possible) depending on whether or not the radio wave transmitted from the public base station 6 that is configured can be normally received and acquired.

  If public access is now possible (YES in step A18), connection to the Internet is made via the public service network 5 and ISP management server 7 (step A19). When a designated site on the Internet is accessed via the ISP management server 7, the designated site is downloaded and received (step A10), and the received site is displayed and output (step A11). Thereafter, various processes according to operations such as page switching can be executed (step A12), and processing according to the operation content is performed until an end operation such as closing is performed (step A13). If public access is not possible (NO in step A18), a message indicating that access is not possible is read and an access impossible screen (see FIG. 5) is guided and displayed (step A20).

  As described above, in this embodiment, the mobile phone device 1 can be connected by selecting a local mobile phone line or a public mobile phone line. The wireless LAN local network (the local base station 2, the local dedicated PBX 3, the local server) 4) If you are in a company premises that has been constructed, when a public mobile phone line is selected and any site on the Internet is designated as an access target, the designated site designated as the access target is restricted in advance. Allow access to the designated site via a public mobile phone line on the condition that it is not a restricted site, and prohibit access to the designated site via a public mobile phone line if it is a restricted site For example, even if you use the Internet with a public mobile phone line selected, you can access restricted sites from the premises. , It is possible to prohibit the access, lowering productivity by ensuring access restrictions, information leakage, it is possible to prevent such circuit burden.

  In this case, the mobile phone device 1 detects whether or not the mobile phone device 1 is within the communication area by performing wireless communication with the local base station 2 constituting the wireless LAN local area network. Even if it is not added, reliable detection is possible. Further, when the cellular phone device 1 makes a URL access request to the local server 4 constituting the wireless LAN local area network, the local server 4 registers and sets the designated site designated as the access target in the restriction list 9. Since it is determined whether or not it is a restricted site and the determination result is returned to the requesting mobile phone device 1, it is possible to request the local server 4 to determine whether or not it is a restricted site. In addition, it is not necessary to set various restricted sites for each mobile phone device 1, and it is possible to uniformly restrict all mobile phone devices 1 in the company, and it is easy to change or add restricted sites. It becomes possible to respond.

  In the above-described embodiment, the local mobile phone line or the public mobile phone line is selected according to the connection button operation. However, the local base station 2 or the public base station 6 is not limited to the line switching by manual operation. The line may be automatically switched by determining whether the communication area is within the private communication area or the public communication area by transmitting / receiving to / from the communication terminal.

  In the embodiment described above, it is detected whether or not the mobile phone device 1 and the local base station 2 are in the local communication area (in the radio wave reachable area) by performing wireless communication. In the cellular phone device 1 including the non-contact IC processing unit 22 that performs wireless communication with a gate device (not shown) with a wireless function installed in a premises such as a doorway, the mobile phone device 1 has passed through the gate device. Whether or not the user is on the premises may be determined by detecting the above by the non-contact IC processing unit 22. Further, in the cellular phone device 1 including the GPS receiving unit 21, it may be detected whether or not the user is on the premises based on the current position information acquired from the GPS receiving unit 21.

  In the embodiment described above, when the mobile phone device 1 makes a URL access request to the local server 4, the local server 4 is a restricted site in which the designated site designated as the access target is registered and set in the restricted list 9. The determination result is returned to the requesting mobile phone device 1, but the mobile phone device 1 determines whether the access-designated site is a restricted site. You may do it. In other words, the cellular phone device 1 receives and acquires the restriction list 9 from the local server 4 and stores and manages it. When an arbitrary site on the Internet is designated as an access target, the designated site is registered in the restriction list 9. The mobile phone device 1 may determine whether or not it is a set restriction site. In this case, the cellular phone device 1 may update the contents of the restriction list 9 by receiving and obtaining the restriction list 9 from the local server 4 periodically or as necessary.

  In the above-described embodiment, the restriction list 9 is exemplified by a list in which URLs such as harmful sites that are arbitrarily set and registered in advance as access restriction target sites are listed. The method is not limited to this, and other methods may be used. That is, a white list method may be used in which a list of URLs of various accessible sites is referred to and only URLs set in the list are accessible. Furthermore, a keyword method, genre method, and phrase that identify harmful sites by adopting a rating method that ranks various sites on the Internet according to a certain standard or analyzing the contents (keyword / genre / phrase) of the site. A method may be used, and how the restriction target is specified is arbitrary.

In the above-described embodiment, access to harmful sites is uniformly restricted regardless of who accessed the site. For example, the user's “title”, “ ”Or the like, the sites that are subject to access restriction may be set differently.
In addition to the harmful sites, the sites subject to access restrictions may be any sites such as entertainment sites as long as they are not directly related to company operations. Of course, the present invention is applicable not only to a company but also to other organizations and general households.

  On the other hand, a recording medium (for example, a CD-ROM, a flexible disk, a RAM card, etc.) on which program codes for executing the above-described units are recorded may be provided to the computer. That is, a computer-readable recording medium having a program code, a function for detecting whether or not it is on the premises, and a public mobile phone line is selected, and an arbitrary page on the Internet is designated as an access target At the time, referring to the detection result, when the user is on the premises, the designated page designated as the access target is not a restricted page set in advance as an access restriction target page, via a public mobile phone line. Can be read by a computer that records a program that implements a function that allows access to the designated page, and if it is a restricted page, prohibits access to the designated page via a public mobile phone line A simple recording medium may be provided.
