Abstract: In order to enable a user to acquire a desired content more quickly by performing a matching process by using search target ID information identifying a search target so as to properly acquire a content regarding the search target and to shorten a time required to complete the matching process, a communication device such as router is configured such that, when receiving an interest form a content-centric network, the communication device performs a search process on contents accumulated therein, aiming to find one or more contents which meet a search criteria set specified by the interest, performs the matching process for verifying whether the content found in the search process matches the search target ID information (face image) to acquire a content regarding the search target, and transmits the acquired content to a communication device of a content request source.

Abstract: To shorten time required to measure communication quality levels, a terminal device selects one of a first or second measurement scheme based on an amount of available bandwidth provided by a current cell in which the terminal device is currently present and other information. When the current cell is provides a largest amount of available bandwidth, the terminal device selects the first scheme, and when the current cell provides a smallest amount of available bandwidth, the terminal device selects the second scheme. When the first scheme is selected, the terminal device measures communication quality levels of communication with all peripheral cells, and when the second scheme is selected, the terminal device acquires current location information on the terminal device, and then extracts one or more of the peripheral cells based on current location information and historical communication information, and measures communication quality levels of communication with the extracted peripheral cells.
