Abstract: The propagation time (1605) of signals between a terminal (1304) and a base station (1302) is calculated from the round-trip time (1601) of signals between the terminal (1304) and the base station (1302) and the turn-around time (1603) from the reception by terminal (1304) of a signal from base station (1302) until the transmission of the signal to the base station (1302). The propagation time (1606) of signals between the terminal (1304) and another base station (1303) is similarly calculated. The difference between the propagation times (1605 and 1606) and the arrival time difference (1607) that is calculated in the terminal (1304) are then compared to calculate the transmission time difference (1608) between the base stations (1302 and 1303).

Abstract: In a content delivery system, a gatekeeping apparatus is connected to a network. Prior to the transmission of a request message to a content server, a user terminal transmits an enquiry message to the gatekeeping apparatus. In response, the gatekeeping apparatus makes a decision as to whether or not a content can be retrieved from the content server and performs control on the transmission of the request message according to the decision. If the decision indicates that a content can be retrieved, the user terminal transmits the request message to the content server. In a preferred embodiment, the gatekeeping apparatus makes comparison between user's preference data and server's policy data and determines whether the requested content can be retrieved from the server. A cache memory may be provided in the user terminal or gatekeeping apparatus to store past decisions regarding requested contents.
