ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a communication-terminal management system and a communication terminal, and, in particular, to a communication-terminal management system having a storage-processing-system network, a real-time-processing-system network, a communication terminal which acts as a terminal of these two networks, and a communication management node of the real-time-processing-system network, and to the communication terminal which is a part of this system.
2. Description of the Related Art
Management of a network interface portion of a complex communication terminal apparatus acting as a terminal of-a storage-processing-system network and a real-time-processing-system network in the related art (for example, setting of an operation environment of a LAN interface board, modem and so forth of a personal computer) is performed in accordance with instructions or the like supplied from a central processing unit (CPU) of the complex communication terminal apparatus. Accordingly, in order to perform complete management, both the CPU and the interface board need to operate. For this purpose, it is necessary to supply power to both the CPU and the interface board and to enable communication therebetween.
In many cases, a personal computer is used as such a complex communication terminal apparatus. When this personal computer is used for telephone calling via a telephone network, a node (for example, a private branch exchange (PBX) or the like) of the telephone network to which the personal computer belongs sets terminal environment information (such as a dial-signal type, function-button information and so forth) for personal computers belonging to the node. In response thereto, on the side of the personal computer, because communication cannot be performed without matching with the terminal environment information set by the node for the personal computer, it is necessary to study the terminal environment information set for the personal computer and to perform setting into a network interface portion of the personal computer such that the thus-set data of the network interface portion matches with the terminal environment information. Such setting into the network interface portion is performed manually (through instructions) on the personal computer which contains the network interface portion. Thus, double setting is needed, i.e, setting into the node and the setting into the personal computer.
Further, in management of a communication history, trouble information and so forth, a storage-device resource such as a memory/hard disk of the complex communication terminal apparatus is used. Therefore, when power supply to the complex communication terminal apparatus comes to be suddenly absent, a writing error of such information, or a fault of such a storage device due to a crash or the like may occur so that the communication history, trouble information and so forth is lost in many cases.
Thus, there are the following problems in the related art:
(1) It is necessary to perform setting in the complex communication terminal apparatus so as to perform setting into the network interface portion contained in the complex communication terminal apparatus after a main power supply to the complex communication terminal apparatus is started. Such setting should be performed such that set data in the network interface portion of the complex communication terminal apparatus matches with set data in the communication management node in the network. Thus, a similar setting is needed to be performed in both the complex communication terminal apparatus and communication management node. Thus, the setting is troublesome. In proportion to an increased number of the complex communication terminal apparatuses, a load to be borne by a communication manager comes to be enormous.
(2) In a case where communication history information, management information and so forth is stored in a hard disk or a memory of the complex communication terminal apparatus, when the main power supply to the complex communication terminal apparatus is absent, it is not possible to read the communication history information, management information and so forth from the hard disk or memory. As a result, there may be a case where trouble information concerning a serious trouble cannot be obtained.
SUMMARY OF THE INVENTION
The present invention has been devised in consideration of the above-described problems, and an object of the present invention is to simplify the management of the complex communication terminal apparatus and to improve the efficiency of maintenance work for the complex communication terminal apparatus.
