Abstract
A maintenance system for subscriber management data in a packet switched network which is to be used when subscriber terminal management data in a packet switching exchange is changed, comprises a step in which a change information file in a data accumulating device is created based on the subscriber terminal change data; a step in which the change of the subscriber terminal management data of a specified subscriber terminal is performed without affecting the communication processes of other subscriber terminals by a multitask process on a packet switching exchange which is remote controlled based on the change information file; a step in which a subscriber accumulation data base file in the data accumulating device is updated in synchronism with the result of a remote control. In the above-mentioned maintenance system, the subscriber terminal information in a packet switched network is unitarily controlled; local data information updating on each of the packet switching exchanges is not needed; a multitask process on each of the packet switching exchanges is made possible, and subscriber terminal management data can be changed without affecting the communication processes of other…
