Method and apparatus for distribution of cipher code in wireless LAN

摘要

A method for distributing a cipher code in a wireless network system including a mobile terminal and a fixed station includes the steps of making a registration request from a mobile terminal to the fixed station as a terminal with which communication is to be made, changing a communication range of the fixed station in accordance with the registration request and distributing an initial cipher code from the fixed station to the mobile terminal while the communication range changed. It is possible to safely make initial registration of a user and to distribute a cipher code used for communication by use of a fixed station alone, to limit the cost of an entire system and to reduce burden to a manager.
