Abstract

PURPOSE:To enable managing the communication management information of each terminal equipment centralizingly at, e.g., a center station of a headquarter by providing a means storing the communication management information of its own equipment and a means outputting the communication management information to a communication terminal equipment to a gateway equipment and a terminal adaptor. CONSTITUTION:In the case of receiving a communication management information LOG output request, a LOG storage section 25 reads LOG information. Then the LOG information is outputted to a communication terminal equipment 15 via a terminal interface control section 23. Moreover, in the case of applying the LOG collection processing of all TAs in the LAN at a gateway GW and output processing to a public network, a LOG request instruction is sent to the terminal adaptor TA. Then the LOG information from the TA is received and the LOG information is stored in a LOC storage section 20. Furthermore, after the said processing is applied to all the TAs in the LAN, the LOG information in the LAN collected already is outputted to the public line via a public network interface 16.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to public networks and local area networks (LAN).
), and relates to a network system equipped with a gateway device that connects.

[Conventional technology] Traditionally, communication terminals (facsimile machines, etc.) installed in geographically distant locations, such as the head office and branch office of a company, were
As shown in the figure, it is common to connect via a public network.

In Figure 9, l is a public network such as a telephone network or digital data network, 2 is a communication terminal device installed at the head office, 3, 4.5
is the communication terminal equipment installed at each branch office.

However, if the scale of the business becomes relatively large and multiple communication terminal devices are installed within the same business, the first O
The configuration shown in the figure is more advantageous.

In FIG. 1O, communication terminal devices 3-1.3-2.3-3 installed within the same office communicate with each other via a local area network (hereinafter referred to as LAN) 6 when performing intra-office communication. Communication terminal device 2 outside the office
, 4.5, etc., communicate with each other via the gateway 7 and the public network 1.

This system can be said to be a rational system because it uses a high-speed, low-cost LAN for intra-office communications, which have a high frequency of communication, and uses the public network only for communications outside the office.

By the way, in network systems, communication management information is generally collected to investigate and manage the usage status of the system and to use it for equipment maintenance. This communication management information includes statistical information (number of times of data transmission/reception, number of times of transmission/reception errors, etc.) and operation history information (chronologically recorded history of internal operations) for each device.

In LAN systems, a dedicated network management device is often connected to the LAN to collect the communication management information.

On the other hand, some communication terminal devices such as facsimiles are equipped with a communication management function that registers a history such as the destination number and communication time for each transmission and reception, and outputs the results as necessary.

[Problems to be Solved by the Invention] However, the conventional system has the following drawbacks.

(1) The network management device that manages the inside of the LAN is relatively expensive, and from an economic standpoint, it is difficult to introduce it into anything other than a large-scale system.

(2) The communication management function of the facsimile machine is output only to the facsimile machine itself. For example, if you want to centrally manage the communication management information of each terminal at a central office such as a head office, it is necessary to collect it from each terminal individually. There is.

[Means for Solving the Problem] As a means for solving this problem, for example, the network system of the embodiment includes a gateway device that connects the public network and the LAN, and a plurality of gateway devices that connect the communication terminal device and the LAN. a terminal adapter device, means for storing communication management information of the own device in the gateway device and the terminal adapter device, and outputting the communication management information to the communication terminal device connected to the terminal adapter device. and means.

[Function] In such a configuration, it is possible to output communication management information in the LAN to any communication terminal device and to output communication management information of all devices in the LAN at once without installing a dedicated network management device. The object of the present invention is to provide a network system having a function of outputting to a communication terminal device connected to a public network.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
