Abstract

PROBLEM TO BE SOLVED: To facilitate a maintenance operation, to protect security, and to record who carries out a maintenance operation at a base station by connecting between a personal computer and a base station through an infrared communication line and confirming whether or not a normal maintenance terminal is used to perform the maintenance of the base station. SOLUTION: In authentication processing, processing is activated by sending a communication start requesting signal from a personal computer side which is a local maintenance terminal 5 to a base station BS2. When the station BS2 receives the communication start requesting signal, it sends communication start response and a starting code requesting signal to the personal computer side. The personal computer side receives them and sends a starting code response signal to the station BS2, and the station BS2 carries out authentication processing by the response signal.

It is a point-to-multipoint connection type based on HDLC using (Infrared Link Access Point). And IrLMP (I
Since a flow control protocol called "nfrared Link Management Protocol" or IrTP is also prepared, a plurality of modules and application programs can be run simultaneously. Simultaneous execution of multiple applications over a single infrared link requires link multiplexing. The part that provides this service is called a multiplexing unit (MUX). In the MUX, the link provided by the IrLAP controller is multiplexed. As a result, even if a plurality of functions are executed simultaneously, the application can determine the identifier from the received MUX, and pass the message without the identifier to the receiving module or task.

Further, as described above, since anyone can change the parameters of all base stations BS by remote control,
It is necessary to ensure security. In the present embodiment, security is ensured by executing the authentication processing shown in the processing sequence of FIG. 3 at the start of communication. That is, the authentication process is performed before performing the initial setting of the communication,
This authentication process is started by transmitting a communication start request signal from the personal computer which is the local maintenance terminal 5 to the base station BS2. Upon receiving the communication start request signal, the base station BS2 sends a communication start response and a start code request signal to the personal computer. In response to this, the personal computer transmits a start code response signal to the base station BS2, and the base station BS2 executes an authentication process using this response signal.

In this authentication process, for example, a system ID is registered in advance in the calculation processing software of the local maintenance terminal 5 (personal computer), and the ID is transmitted from the base station BS2. (The calculation method of the personal computer software differs depending on the system), and the result is written in a start code response signal and transmitted to the base station BS2. The base station BS2 checks the calculation result. If the calculation result is correct, the base station BS2 sends a communication start acceptance signal, performs communication initial setting, and starts serial communication and remote processing. By registering the system ID in the personal computer in this way, remote software dedicated to the system can be realized, and when local remote control is accepted, a log of maintenance work performed by the maintenance person can be recorded. Note that the authentication process is not limited to the method of registering the system ID as described above. For example, as disclosed in Japanese Patent Application Laid-Open No. 7-274258, a specific random numerical value is calculated by the same formula. Or a method that matches the quotient.
It is only necessary to be able to recognize that a predetermined personal computer is being used.

As described above, in the local maintenance terminal of the present invention, an existing infrared communication function of a recent personal computer is provided on the base station side, the maintenance terminal is connected to the base station via an infrared communication line, and communication is started. At the same time, authentication processing to determine whether or not a legitimate maintenance terminal is being used is performed, so that local maintenance without removing the base station installed on the ceiling or wall can be performed at high speed using a wireless section. It can be implemented by control. Further, the security of the system is protected by the authentication processing, and the maintenance terminal used by each of the companies can be identified. Further, since the log of the maintenance person remains, the base station side can record who operated the system data of the base station, and the maintenance operation can be recorded on the maintenance terminal side.
