Abstract: A content distribution system uses a PtP (point to point) channel (individual channel) or PtM (point to multi-point) channel (common channel) as a radio channel of a predetermined type so as to distribute a broadcast content as communication data to a user terminal as a mobile station. The user terminal receives the same content distributed from a broadcast content server by the PtP channel. Here, if the total of the downlink transmission power of the PtP channel is greater than the downlink transmission power of the PtM channel when the content is distributed to the user terminal by the single PtM channel, a base station or a base station control device judges that the radio channel is to be switched from the PtP channel to the PtM channel. Similar judgment is made when switching from the PtM channel to the PtP channel is performed. Thus, it is possible to switch the radio channel type used for the broadcast-type service without lowering the use effect of the radio resources.

Abstract: A mobile terminal transmits an N-th authentication key to an authentication server when the mobile terminal has moved from a coverage area under a certain radio access point to a coverage area under another radio access point. The N-th authentication key is generated by applying a hash function to a random number a number of times one smaller than an (N?1)th authentication key which was transmitted when the mobile terminal moved to the coverage area under the certain radio access point. Upon receipt of the N-th authentication key from the mobile terminal, the authentication server applies the hash function once to the N-th authentication key, and compares the result with the (N?1)th authentication key. Then, the authentication server determines that the authentication is successful when there is a match between both keys.
