The above-mentioned user interface process 23 is generated by interpreting/executing means 22 by interpreting and executing HTML data received from receiving means 21. The type of data inputted by the operating means 25 can be switched in accordance with instructions of the user interface process 23.

Abstract: The communication state information providing system comprises a cellular phone of an information provider, and an information providing device having an information receiving unit for receiving, via a wireless LAN, the communication state information transmitted from the cellular phone, a communication state information storage unit for storing the communication state information received by the information receiving unit associated with the phone number specifying the cellular phone, and an information transmitting unit for transmitting the communication state information stored in the communication state information storage unit to a destination associated with the phone number of the cellular phone.

Abstract: When an application is activated, a mobile station 10 detects external devices 20, 30, 40 as candidates for a BLUETOOTH connection out of external devices existing in the surrounding area, and presents a list of the devices to a user. When the user selects from the list an external device 20 with which a connection is to be attempted to make, a link is established by a connection procedure according to a security level described in an ADF of the application. Namely, when “high” is described as the security level, an authentication process and an encryption process requiring input of a PIN are executed prior to the establishment of the link. On the other hand, when “low” is described as the security level, a link is established without executing these processes.

Abstract: The present invention has the purpose of providing technology capable of efficiently transmitting data when performing data communications between a mobile station and a server apparatus. A simplified protocol TL is employed on the transport layer instead of TCP/IP. The simplified protocol TL is used as the communication protocol on a wireless communication path (radio-oriented interval) between an MS (Mobile Station) 1 and a GWS (GateWay Server) 5. The simplified TL protocol is utilized to relay data communications between the MS 1 and a CPS 8 (Content Provider Server). The response of data communications is therefore improved by a decrease in traffic between the MS 1 and the GWS 5 and reduction in overhead in comparison to when TCP/IP is deployed. As a result, the user can efficiently access content provided by the CPS 8 over the Internet via a wireless communication path.

Abstract: The user of a mobile station which is prepared to receive information providing services from unspecified IP (Information Providers) accesses a gateway server and performs a pre-registration procedure (S71). When an IP server has information to provide to users, it constructs the information in the form of electronic mail, appends user attribute data, and sends this to the gateway server (S72). Upon receiving electronic mail with attribute data, the gateway server stores the electronic mail in a third mailbox, makes a comparison of the user attributes, and calls the mobile stations of relevant users (S73). A user who has received a call requests a download of the electronic mail from the gateway server (S74). The gateway server sends electronic mail to the mobile station which made the request (S75, S76).

Abstract: There is provided a message delivery system which does not generate the lack of the message, by making possible to issue an instruction to the server unit from the client system to process a message, which is received by the client system, at a timing when the client system has completed to receive the message as the application, and then performing the message process on the server unit side in compliance with the instruction.

Abstract: There is provided a communication system capable of reducing the burden of the terminal that is connected to the Internet via the communication network such as the mobile telephone network, whose security is ensured, and is used to carry out the electronic commerce and the banking service. An encryption communication request generating portion (101) of a client system (100) sends out a security request of a communication route to a gateway server unit (200), an encryption communication controlling portion (203) of the gateway server unit sets up encryption communication between a content server unit (300) and the gateway server unit in response to this, the content server unit encrypts data to be transmitted to the client system and then transmits it to the gateway server unit, and an encryption communication controlling portion of the gateway server unit decrypts this data and transmits it to the client system.

Abstract: In a transmission circuit, part of the output signal of the transmission circuit is diverted by an output monitor circuit and subjected to envelope detection by an output detector circuit. The output signal of the output detector circuit is inputted to a peak hold circuit successively holding the peaks of the input signal, so that varying amplitude components are removed, and a DC value is detected. An error detector circuit compares the detected value with a reference signal from a reference signal generator circuit, and the error signal is used as a gain control signal to control the gain of a power amplifier circuit.
