理装置を提供することにある。The above-mentioned prior art is mainly used for toll collection on toll roads, and does not cause a problem of charging for communication. However, when considering the use of the above-mentioned communication method for purposes other than toll collection on toll roads, there is a need to charge for the communication itself and a need to charge for receiving toll contents through the communication. In this case, it is conceivable that a third party intercepts the mobile station identification information and performs unauthorized communication using the identification information. Furthermore, if the communication purpose is not completed at one time like automatic toll collection but is performed continuously, handover between base stations is required. In this case, a base station management device that manages a plurality of base stations is required. However, if the mobile station authentication operation for each base station is not performed in consideration of communication efficiency, the mobile station may be shared through a plurality of base stations. Identification information will be assigned. In this case, if the mobile station identification information is intercepted, a third party will perform communication in the communication jurisdiction of the base station management device. SUMMARY OF THE INVENTION An object of the present invention is to provide a mobile station device, a base station device, and a base station management device capable of preventing a third party from intercepting mobile station identification information and performing communication by impersonating the same, in order to solve the above problems.
