DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fault monitoring and notification system for a private paging system.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a conventional private paging system. The private paging system shown in FIG. 3 transmits private contact information by a private branch exchange 20 accommodating a plurality of extension telephone terminals 10 and switches installed at nurse stations or the like and corresponding to individual wireless calling terminals, and issues a call request for the wireless calling terminal. , A personal computer 40 that performs operation management / maintenance management of the system, and a transmitter 40 that transmits a paging signal to the paging terminal are connected to the radio transmission device 60.

[0003] When a caller (not shown) is called from the extension telephone terminal 10, the caller dials the desired radio call terminal number with the extension telephone terminal 10, and the wireless transmission device 60 is transmitted via the private branch exchange 20. The voice response device 61 of the wireless transmission device automatically reproduces the guidance information prompting the message input to the wireless calling terminal and returns it to the caller.

[0004] The voice response control unit 62 converts the terminal number of the radio paging terminal into an address signal which is a radio paging terminal identification signal, and encodes the code according to a predetermined radio signal format together with the message signal input from the extension telephone terminal 10. Then, a selective call signal is generated, modulated by a predetermined modulation method by the radio call control unit 66, and transmitted simultaneously from the transmitter 50 at the same frequency.

[0005] In the conventional private paging system, the main control unit 70 of the wireless transmission device 60 includes a voice response control unit 62,
All functions of the emergency call control unit 64 and the wireless call control unit 66 are controlled. In addition, the personal computer 40
Interfaced in S232C, registration / update of system data is performed. A dedicated extension telephone terminal (not shown) is installed in the personal computer 40 and housed in the private branch exchange 20 together with the other extension telephone terminals 10.

In the failure notification system in this private paging system, an operation / maintenance manager notifies from a dedicated extension telephone terminal of the personal computer 40 when responding to a call request to the radio paging terminal.

[0007]

In the conventional local paging system, there is no means for notifying the system failure from the system (wireless transmission device) side to the personal computer 40 when a system failure occurs. When a call request was made from a dedicated extension telephone terminal, it was notified that the system was faulty when the call was answered.
The maintenance manager cannot know in advance that the on-site paging system is faulty, so that there is a problem that the fault response is delayed.

Further, since the fault information is simply information indicating that the system is faulty, the location of the fault, that is, which of the voice response control unit, the emergency call control unit, and the radio signal control unit has failed is unknown. Therefore, it took time to specify the location of the failure, and it was difficult to quickly restore the location.

Furthermore, since the main control unit centrally controls all functions of the wireless transmission device, there is a problem that when a failure occurs in the main control unit, all functions stop and the system goes down.

An object of the present invention is to provide a system in which, when a fault occurs, the system automatically sends fault information specifying a fault location in functional units to a personal computer for operation / maintenance management,
It is an object of the present invention to provide a failure notification method of a private paging system that can notify a failure location to an operation / maintenance management device using audio information and visual information.
