Patent ID: 8613049

Claim:
A network system comprising: a reading apparatus for reading user identification information of a user; a first management apparatus for managing the user identification information read by the reading apparatus; and a second management apparatus for managing at least one communicating terminal which can communicate with a network, wherein the first management apparatus comprises a discrimination unit adapted to discriminate, based on the user identification information of the user read by the reading apparatus, before the user enters a certain area, whether an entrance of the certain area is to be locked or unlocked so as to permit or not to permit the user to enter the certain area, and wherein the second management apparatus comprises: (a) a first reception unit adapted to receive the user identification information of the user from the first management apparatus; (b) a second reception unit adapted to receive terminal identification information of one of the at least one communicating terminal from the one communicating terminal; (c) a registration unit adapted to register, in a management table, the terminal identification information of the one communicating terminal received by the second reception unit in correspondence to the user identification information of the user, if the discrimination unit discriminates that the user is permitted to enter the certain area; (d) a deletion unit adapted to delete the terminal identification information from the management table, if the reading apparatus reads the user identification information of the user when the user is to leave the certain area; and (e) a control unit adapted to control the communication between the one communicating terminal and the network on the basis of a registration situation of the terminal identification information in the management table such that the communication is permitted while the terminal identification information is registered in the management table and the communication is not permitted while the terminal identification information is not registered in the management table.
