Latest Patents
One of Ryu's latest patents is titled "Apparatus and method for reselecting a public land mobile network in a mobile communication terminal." This invention provides a method for reselecting a Public Land Mobile Network (PLMN) in a mobile communication terminal. The method includes requesting the updating of location registration to a target PLMN after storing current system information. It also determines whether a Subscriber Identify Module (SIM) card is valid when it fails to update the location registration. If the SIM card is invalid, the method resets it to a previous state and reads the stored current system information to request the updating of location registration in the current PLMN.
Another significant patent is "Apparatus and method for providing call-processing service in GSM/GPRS mobile terminal." This invention includes an apparatus that provides a call-processing service in a mobile terminal. The apparatus consists of a circuit processor that provides a Circuit Service (CS) and a packet processor that provides a Packet Service (PS). It also features a period measuring unit that measures a delayed paging period in which a call-processing signal is detected while the PS is provided. The monitoring unit shifts the PS to a standby mode during the delayed paging period if the packet processor is receiving the PS and controls the circuit process to provide the CS if the call-processing signal is received.
