  • Patent number: 9027160
    Abstract: A secure element (SE) unit 102 holding service data used by an application is provided in a UIM card 100. Thus, when the user identify module (UIM) card 100 is transferred between portable terminals, service data and accompanying information of the application can be moved together with the UIM card 100 to another portable terminal. In addition, an access management unit 400 included in a portable terminal 200 compares UIM information of a UIM information storage unit 103 with UIM information, held by an authority information holding unit 205, 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 unit 102 is restricted.

  • Patent number: 8949319
    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).

  • Patent number: 8121488
    Abstract: 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.

  • Patent number: 7716475
    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.
