  • Patent number: 8874128
    Abstract: A system and method for detecting a location of a mobile communication terminal. A mobile communication network for communication with the terminal and a cell identifier (ID) of a base station is set. A public land mobile network (PLMN) ID of the network and the cell ID are stored. One or more networks other than the set network are searched for. When the one or more other networks are searched for, the searched one or more other networks are sequentially set. Cell information according to the one or more other networks is searched for. Cell IDs of base stations communicable with the terminal are set. PLMN IDs of the one or more other networks and the cell IDs are stored. A common area between cells set using the stored PLMN and cell IDs is determined. Information about the common area is detected as location information of the terminal.

  • Patent number: 8516127
    Abstract: A method and system for maintaining connections between a terminal and a plurality of servers in a stand-by state in which the terminal is connected to the servers. The terminal generates timers for maintaining the connections to the servers. The terminal determines whether a timer expires. When the timer expires, the terminal simultaneously sends packets for connection maintenance notifications to all the servers having communication connections to the terminal.

  • Patent number: 7664923
    Abstract: A method and a system for updating software stored in a flash memory, which enables a user to resume a suspended updating process even when log data stored in a journaling area is lost. According to the present invention, log data indicating the results of implementation of each step of the updating process is stored in a journaling area allocated in a flash memory to update the software. The data stored in the journaling area is copied into a first backup journaling area allocated in the flash memory whenever each step is completed. Concurrently, log data indicating the copying results is stored in a second backup journaling area.

  • Publication number: 20070091894
    Abstract: Disclosed is a system, apparatus and method for improving a transmission rate by using an ACK piggybacking of a TCP in an asynchronous network environment. When an ACK packet for confirming reception of TCP data downloaded from a sender is transmitted, the ACK packet piggybacks another IP packet (or an IP datagram) to be transmitted through an uplink, i.e. the ACK packet is transmitted together with the IP packet. This removes congestion between the ACK packet and the IP packet, which are transmitted through the uplink, and reduces loss or delay of the ACK packet, which deteriorates the transmission rate.

  • Publication number: 20040214611
    Abstract: A mobile terminal and method for displaying a web site using previous display information. In the mobile terminal, a memory stores previous display information of a web page previously visited by a user. A controller performs a control operation so that the loaded web page is displayed on a display unit after the controller detects the previous display information of a loaded web page from the memory. In the method, a web page is loaded if the user accessing a wireless Internet requests the mobile terminal to visit the web page. The previous display information of the loaded web page is detected from an internal memory of the mobile terminal and the loaded web page is displayed utilizing the display information. As a result, the mobile terminal and method enable users to easily use the wireless Internet.
