  • Patent number: 7289817
    Abstract: A file downloading apparatus of a mobile terminal in a mobile communication system, includes a signal processing unit which processes a signal received through an antenna of the mobile terminal, a memory which stores data outputted from the signal processing unit, a download status checker which checks the download status of a file by monitoring the data stored in the memory, and a CPU which controls the signal processing unit and the download status checker. In the file downloading mechanism, it is possible to resume downloading of the file from the point at which the download was stopped in the previous data transfer session even though the data transfer link is broken during the downloading of the file due to unexpected network problems or other problems.

  • Publication number: 20060089173
    Abstract: An apparatus and method for utilizing a trunk in a mobile communications system capable of efficiently utilizing and operating the trunk when accepting subscribers for various services in one base station, wherein the one base station can accept subscribers for mobile communications services in any mobile communications system using different frequency bands, respectively, a traffic can be simply divided only by performing a base-pass filtering, the changed amount of the traffic can be monitored and measured in a real-time manner, so that interface links such as lub or Abis do not have to be connected individually to be appropriate for each type of mobile communications services, but rather the minimum number of links are connected so as to efficiently operate the links.
