In an authentication method for a radio communication system including a plurality of base stations, a plurality of radio communication terminals each capable of communicating with any one of the plurality of base stations, and a telephone network having a plurality of exchangers connected to the plurality of base stations and a communication managing apparatus capable of controlling the exchangers, each of the plurality of radio communication terminals has stored therein identification data different from the other radio communication terminals, The communication managing apparatus has stored therein identification data of the radio communication terminals permitted to access the radio communication system. When any of the radio communication terminals attempt a connection through the base station to the telephone network, it is examined whether or not the identification data stored in the radio communication terminal coincide with, any of the identification data which is stored in the communication managing apparatus and assigned to radio communication terminals permitted to access the telephone network. If it is confirmed that the identification data of both coincide with each other, the radio communication terminal is connected to the telephone network, and the identification data stored in the radio communication terminal and the communication managing apparatus are updated with new data at every connection made between the radio communication terminal and the telephone network. |

DETAILED DESCRIPTION Therefore, it is a general object of the present invention to provide an improved authentication method, a radio communication system, a radio communication terminal, and a communication managing apparatus in which the aforesaid shortcomings and disadvantages encountered with the prior art can be eliminated.
More specifically, it is an object of the present invention to provide an authentication method for a radio communication system which makes it difficult to carry out illegal communication using identification data illegally deciphered.
According to the present invention, there is provided an authentication communication method for a radio communication system, a radio communication system, a radio communication terminal and a communication managing apparatus in which identification data stored in a radio communication terminal and a communication managing apparatus is updated with new data at every connection made between the radio communication terminal and a telephone network.
Therefore, even if the identification data is illegally deciphered, it becomes difficult to carry out illegal communication using the identification data illegally deciphered.
Accordingly, illegal utilization of the communication terminal can be effectively prevented.
The above and other objects, features, and advantages of the present invention will become apparent form the following detailed description of an illustrative embodiment thereof to be read in conjunction with the accompanying drawings, in which like reference numerals are used to identify the same or similar parts in the several views.
