A secure element (SE) unitholding service data used by an application is provided in a UIM card. Thus, when the user identify module (UIM) cardis transferred between portable terminals, service data and accompanying information of the application can be moved together with the UIM cardto another portable terminal. In addition, an access management unitincluded in a portable terminalcompares UIM information of a UIM information storage unitwith UIM information, held by an authority information holding unit, of a UIM card of which use authority is possessed by an application. If they do not agree, access to service data stored in the SE unitis restricted.

Access management system and access management method

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 (S). 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 (S). 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 (S). A user who has received a call requests a download of the electronic mail from the gateway server (S). The gateway server sends electronic mail to the mobile station which made the request (S, S).

Transfer device

A communication terminal () including a first communication unit () and a second communication unit () includes a presence status detection unit () that detects a presence status indicating whether a distance from a personal computer () is inside a communication range where communication is possible or outside the communication range where communication is not possible for each of the first communication unit () and the second communication unit (), and a communication status management unit () that, in accordance with the presence status of either communication unit () detected by the presence status detection unit (), causes the other communication unit () to transition to an activation state, a standby state or a disconnection state.

Communication terminal and communication control method

A reproducing apparatus () of the present invention receives information of a WEB site from a service-providing server () that administrates the WEB site, and reproduces the information. The service-providing server () holds identification information () of a user of a portable communication apparatus () that is permitted to access the WEB site. The reproducing apparatus () includes: a data receiving section for receiving, from the portable communication apparatus (), invitation information (), identification information (), and transmission time point information (); a reproducing apparatus infrared communication section; a destination determination section that establishes a connection to the service-providing server () based on the received invitation information (), and transmits the invitation information (), the identification information (), and transmission-instruction time (); and a reproducing apparatus communication control section. This allows the administrative server to confirm an authorized destination, based on the content request information received from the portable communication apparatus, when a content is provided from the administrative server managing the content.

An infrared communication apparatus and method enabling data communication with a receiving device, regardless of a protocol with which the receiving device is compatible. A transmitting unit transmits a first packet to inquire whether a receiving device is compatible with a first protocol and transmits a second packet to inquire whether the receiving device is compatible with a second protocol, to the receiving device at least once, and transmits a plurality of third packets to inquire whether the receiving device is compatible with a third protocol, to the receiving device. A receiving unit receives a response packet indicating a protocol with which the receiving device is compatible, from the receiving device having received the first packet, the second packet, and the plurality of third packets. A data transmitting unit transmits data to the receiving device, based on the protocol indicated by the response packet received by the receiving unit.

When an application is activated, a mobile stationdetects external devicesas 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 devicewith 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.

Mobile station and communication control method

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.

A transmission-reception device receives site screen data transmitted from an IP server. An SRAM records the site screen data received by the transmission-reception device. When in a reception standby state, the CPU reads the site screen data recorded in the SRAM, generates a site screen, and displays this on the liquid crystal display.

Portable telephone and terminal equipment

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)and a GWS (GateWay Server). The simplified TL protocol is utilized to relay data communications between the MSand a CPS(Content Provider Server). The response of data communications is therefore improved by a decrease in traffic between the MSand the GWSand reduction in overhead in comparison to when TCP/IP is deployed. As a result, the user can efficiently access content provided by the CPSover the Internet via a wireless communication path. Efficient access may occur even where the wireless communication path has low data transmission capacity in comparison to a wireline communication path. In addition, efficient access may occur where the user is using an MSwhich has insufficient data processing power to deploy TCP/IP.

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 ( ) of a client system ( ) sends out a security request of a communication route to a gateway server unit ( ), an encryption communication controlling portion ( ) of the gateway server unit sets up encryption communication between a content server unit ( ) 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. Encryption/decryption processing systems are not needed in the client system and thus the burden can be reduced.
