| 20080242297 | METHOD FOR SEARCHING FOR NETWORK IN RADIO COMMUNICATION SYSTEM - A method for improving the network search rate by reducing the manual network search time in a radio communication system. System information messages are periodically broadcast, and the messages include a Master Information Block (MIB) containing location area information regarding at least one Public Land Mobile Network (PLMN). The MIB of the system information message received from the network is read during a network search by a User-Equipment (UE), displaying a PLMN list, and reading a System Information Block (SIB) of a PLMN selected from the PLMN list. | 10-02-2008 |
| 20090011786 | METHOD AND APPARATUS FOR CONTROLLING POWER FOR TRANSMISSION OF A PREAMBLE IN A MOBILE COMMUNICATION SYSTEM - A method and an apparatus for controlling power for transmission of a preamble for acquisition of a channel are provided. The method for controlling power for transmission of a preamble includes calculating an initial preamble transmission power using an initial power calculated using information broadcast through a forward common channel and a stored difference value, transmitting the preamble through a backward common channel with the initial preamble transmission power and replacing the stored difference by a difference obtained by subtracting the initial power from the initial preamble transmission power and storing the obtained difference instead of the stored difference, when an acknowledge to the preamble is received. | 01-08-2009 |
| 20090017820 | CELL SELECTION METHOD AND MOBILE TERMINAL USING THE SAME - A mobile terminal and cell selection method for the same are provided. The cell selection method includes receiving a system information message from a first communication system, extracting information regarding a second communication system from the received system information message and selecting a cell of the second communication system using the extracted information, wherein information on cells of the second communication system neighboring a cell of the first communication system is extracted from the system information message. Accordingly, the present invention improves efficiency and reduces power consumption in a mobile communication terminal. | 01-15-2009 |
| 20090061864 | MOBILE COMMUNICATION SYSTEM AND CELL SEARCHING METHOD THEREOF - A mobile communication system and cell searching method of the mobile communication network is provided for simplifying a synchronization process required for selecting a target cell. The cell searching method for a mobile communication system includes transmitting, at a base station, a first synchronization signal of a first slot of a frame of a first channel at a higher transmission power than a transmission power of a remainder of the frame of the first channel, acquiring, at a mobile station, a slot synchronization using the first synchronization signal, and acquiring, at the mobile station, a frame synchronization using a second synchronization signal of a second channel, wherein the second synchronization signal corresponds to the first synchronization signal. | 03-05-2009 |
| 20090325641 | METHOD AND APPARATUS FOR DETERMINING VALIDITY OF MOBILE SUBSCRIBER IDENTIFIER IN MOBILE COMMUNICATION TERMINAL - 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. | 12-31-2009 |
| 20100009680 | APPARATUS AND METHOD FOR SEARCHING SERVICE BAND IN A MOBILE COMMUNICATION TERMINAL - An apparatus and method for service band search in a mobile communication terminal are provided. The method includes receiving system information from a Base Station (BS), extracting information identifying a band supporting a network or a service intended for access using the received system information, and searching the identified band for a service band. | 01-14-2010 |
| 20100056143 | APPARATUS AND METHOD FOR SERVICE REGISTRATION IN A MULTI MODE PORTABLE TERMINAL - An apparatus and method for service registration in a multi mode portable terminal are provided. The apparatus includes a system registration manager for, if a rejection corresponding to service disability is generated during a registration process with a first network, processing to reboot the multi mode portable terminal. | 03-04-2010 |
