  • Patent number: 8675548
    Abstract: Provided is an apparatus and method for providing a packet service in a mobile communication system. An RNC broadcasts an SIB signal including Always-On availability information. Upon receipt of an RRC connection request message for requesting an Always-On mode, the RNC maintains a preservation state in communication with a core network. A UE detects the Always-On availability information in the SIB signal received from the RNC to determine whether the Always-On mode is available. If the Always-On mode is available, the UE generates the RRC connection request message to transmit the generated RRC connection request message to the RNC.

  • Patent number: 8606318
    Abstract: A method and an apparatus for determining validity of a mobile subscriber identifier in a mobile communication terminal are provided. In the method, a temporary identifier assigned from a network is stored in a memory and a SIM card of the terminal. When a network authentication event occurs, the temporary identifier stored in the memory is compared with the temporary identifier stored in the SIM card. An identifier to be transmitted to the network is determined among an International Mobile Subscriber Identity (IMSI) and the temporary identifier stored in the SIM card depending on a result of the comparison.

  • Patent number: 8310954
    Abstract: An apparatus and method for decreasing the number of bearer connections by transmitting a data packet in order to determine a network connection status at a time of bearer connection necessarily performed by a portable terminal together with a location registration message. Reduced battery consumption in the portable terminal is achieved because of the reduced number of bearer connections. The apparatus includes a transmission time determination unit for reconfiguring a data packet transmission time to a time of bearer connection necessarily performed by the portable terminal when a data packet is transmitted to determine the network connection status, and a controller for providing control to transmit the data packet is transmitted while connecting the bearer at the reconfigured data packet transmission time, wherein the reconfigured data packet transmission time may be advanced or delayed of the initial transmission time.

  • Patent number: 7898997
    Abstract: Provided is a method for measuring a neighbor cell signal in a portable terminal includes acquiring a minimum required quality level value and a threshold for an intra-frequency measurement from received system information; calculating a measured cell quality value after the acquiring step; and commencing a neighbor cell signal measurement for an intra-frequency cell reselection when a value acquired by subtracting the minimum required quality level value from the measured cell quality value is less than or equal to a value acquired by adding the threshold and a certain signal strength value over a certain time. In the neighbor cell signal measurement for the cell reselection, the unnecessary neighbor cell signal measurement can be avoided to reduce the power consumption and extend the battery lifetime.
