When contents server CPreceives the above-mentioned HTTP request, CPdetermines whether the requested contents are allowed to be transmitted abroad by referring to the transmission table. When transmission of the requested contents is not permitted, contents server CPtransmits an error notification to mobile unit MS to notify that transmission is not permitted.
