Abstract: A transmitting apparatus transmits its own identification information to a terminal station and controls the terminal station to transmit to a relay apparatus a delivery permission registration request including the identification information and the email address of the user of the terminal station. On receiving the delivery permission registration request, the relay apparatus, then, stores in a delivery permission table the identification information of the transmitting apparatus corresponding to the email address, and controls the terminal station to transmit to the transmitting apparatus recipient registration request including the email address. Finally, the transmitting apparatus stores in a recipient list the email address included in the received recipient registration request.

Abstract: Mobile device MS displays an unreceived mail list acquired from gateway server GWS by executing a browser. A user selects a desired e-mail by referring to the unreceived mail list. Prior to that gateway server GWS transmits e-mails to mobile device MS, gateway server GWS transmits to mobile device MS, an HTML header including predetermined character strings which are a field name (X-IMTMAIL) and a field value (WEB). Then, mobile device MS activates a mailer, and prepares to receive and store e-mails transmitted from gateway server GWS.

Abstract: Mobile phone 100-1 adds information that indicates the extensions of attachment files the user desires to obtain to an HTTP request for obtaining e-mail, and sends the HTTP request to a mail server 400. When mail server 400 receives the HTTP request, it compares the files attached to the e-mail with information included in the HTTP request, and determines whether to send the attachment files. In a case where it is determined not to send an attachment file, mail server 400 deletes the attachment file from the e-mail, and sends the e-mail from which the attachment has been deleted to mobile phone 100-1.

Abstract: Character strings for selecting received emails are registered in an email server apparatus (600). When receiving an email addressed to the user of a mobile phone (700), the email server apparatus (600) uses the character strings to select the email. When it is during a trial period, the email server apparatus (600) delivers the received email with a selection result addressed thereto. When it is after the trial period, the email server apparatus (600) retains, as a history, information about the received email, and periodically transmits the history to the mobile phone (700).

Abstract: A provider code is added to a request signal transmitted to contents server SP1 from mobile unit MS by mobile communication network GSM. Border switching station CMMS adds a roaming flag to the request signal, and forwards the request signal to gateway unit GW. Gateway unit GW converts the provider code contained in the request signal into the country code by referring to the code conversion table, and transmits HTTP request to contents server CP1 after adding the country code and roaming identification information to HTTP header. When contents server CP1 receives the above-mentioned HTTP request, CP1 determines 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 CP1 transmits an error notification to mobile unit MS to notify that transmission is not permitted.

Abstract: Email server 25 comprises email storage unit 254a for storing ordinary emails and email receipt storage unit 254b for storing only email receipts. When email server 25 receives an ordinary email, which is addressed to mobile station 10, email server 25 stores the email in email storage unit 254a temporarily, and transmits it to mobile station 10. On the other hand, when email server 25 receives an email receipt which is addressed to mobile station 10, email server 25 stores the email receipt in email receipt storage unit 254b, and transmits the email receipt in response to a request transmitted by mobile station 10 following; an operation carried out by a user of mobile station 10.

Abstract: By storing data of web page in a different server from the one which stores a web page data, the work is distributed and the load on the server is reduced. Content server 400 provides mobile telephone 100 with web page data which has a statement of directing to get banner advertisement data in web pages from advertisement server 500. Mobile telephone 100 which receives web page data obtains banner advertisement data from advertisement server 500. In order to view a web page linked by the banner advertisement, mobile telephone 100 obtains from advertisement server 500 a URL for a linked web page, and obtains the linked web page data.
