A mobile terminal that obtains location information and information of an identifier of an area in which the mobile station resides. The mobile station causing the location information to be obtained in a case that the identifier of the area in which the mobile terminal currently resides is different from an identifier of an area in which the mobile terminal resided in the past. The mobile terminal then reports the location information to a server.

Mobile terminal and battery saving method in mobile communication system

A terminal device in which basic information and detailed information of each a plurality of application programs are stored in a different storage area for each application program, and that prohibits access to each storage area by other application programs, is caused to execute the processes of displaying a window that includes the basic information of each application program, and, if a cursor is moved to the display position of one of the pieces of basic information, launching, in an information providing mode, a first application program where the cursor is positioned and a second application program whose basic information is displayed adjacent to the first application program to acquire the detailed information of the application programs, and displaying the detailed information of the first application program.

Terminal device and program

A content transaction management server device includes: a memory storing decryption keys used in decryption of encrypted content data; a communication unit for information; a payment-request reception unit receiving, through the communication unit, a first storage address indicating a storage area where the decryption keys of encrypted content data in the memory are stored and user identifiers identifying users who are purchasers of the encrypted content data; a payment-procedure processing unit implementing payment-procedure processes related to purchase transactions of encrypted content data by a user identified by user identifiers in the payment request; and a decryption-key transmission unit that, after payment-procedure processing based on the payment-procedure processing unit is completed, reads out, from the memory, decryption keys stored in the storage area indicated by the first storage address included in the payment request and transmits, through the communication unit, the decryption keys to the transmission source of the payment request.

Content transaction management server device, content-providing server device, and terminal device and control program

A terminal device in which basic information and detailed information of each a plurality of application programs are stored in a different storage area for each application program, and that prohibits access to each storage area by other application programs, is caused to execute the processes of displaying a window that includes the basic information of each application program, and, if a cursor is moved to the display position of one of the pieces of basic information, reading out, from the appropriate storage areas, the detailed information of a first application program corresponding to the basic information where the cursor is positioned and the detailed information of a second application program whose basic information is displayed adjacent to the basic information of the first application program, and displaying the detailed information of the first application program.

A content distribution system includes a content distribution management device and a communication terminal. A storage unit stores one or a plurality of addresses. A receiving unit receives content data addressed to a communication terminal. A determination unit determines whether or not the address of the origin of the received content data is an address that is stored in the storage unit. A sending unit where the determination unit has determined that the address of the origin of the received content data is stored in the storage unit, sends the content data and parameters specifying the format in which content is to be displayed to a communication terminal. The communication terminal includes a receiving unit that receives parameters and content data from the content distribution management device; and a content display control that controls the display format in accordance with received parameters.

Content distribution management device, terminal, program, and content distribution system

A communication terminal providing optimal communication services between content providers comprising a property management table with an appraised value registered for each of a predetermined set of communication media properties for various types of communication media, a first user specified priority ranking list and a second priority ranking list specified by an application program provider with rankings for the set of communication media properties, whereby the desired communication medium is selected by adding weightings for priority from the first and second priority ranking lists and adding the appraised value for each item from the property management table and using the highest total to specify the optimum communication medium for use when commencement of communication is specified by a predetermined application program, and establishing communication connections between opposing devices using the selected optimum communication medium. Also disclosed are a communication system, control device and program including the communication terminal's elements.
