20090286527 | Apparatus and a method for service continuity between umts network and wlan network - Service continuity is provided between a 3GPP network and a non-3GPP network. When a mobile station having accepted service in the 3GPP network moves to the non-3GPP network or returns from the non-3GPP network to the 3GPP network, an interworking gateway is interworked with a GGSN through a universal tunnel using a packet data network, and accordingly a mobile subscriber may accept seamless service. | 11-19-2009 |
20100254333 | METHOD OF TRANSMITTING AND RECEIVING RANDOM ACCESS RESPONSE INFORMATION IN RADIO COMMUNICATION SYSTEM, AND BASE STATION AND TERMINAL THEREOF - The present invention relates to a method of transmitting/receiving random access response information in a radio communication system, and a base station and a terminal thereof. According to the invention, in a case where a base station of a radio communication system transmits response information for random access processing requested from terminals, the base station determines whether to transmit non-contention-based response information and contention-based response information for each of one or more terminals, which requests random access, by one radio resource. When determining to be transmitted by one radio resource, the base station transmits the random access response information configured by the non-contention-based response information and the contention-based response information for each of one or more terminals. In addition, when determining to be transmitted by separate radio resources, the base station transmits the random access response information configured by the non-contention-based response information or the contention-based response information for each of one or more terminals. Accordingly, since the response information is efficiently configured from the point of view of allocation and utilization of radio resources, it can support variable and flexible utilization of physical layer radio resources. | 10-07-2010 |

20130201154 | TOUCH SCREEN DEVICE, AND DRIVING DEVICE AND DRIVING METHOD FOR TOUCH PANEL - A driving circuit outputs driving waveforms to operation signal lines. The waveforms are formed by combining a first-mode waveform for charging a node capacitor with a positive voltage and a second-mode waveform for charging the node capacitor with a negative voltage in a predetermined binary sequence. A sensing circuit is electrically connected with a plurality of sense signal lines and measures sense voltages delivered to one integration capacitor from a plurality of node capacitors which are electrically connected with the sense signal lines. A sense detector adds or subtracts the sense voltages which are measured by the sensing circuit at driving time points to measure capacitances of the node capacitors. Accordingly, an autocorrelation technique which is generally used in communication systems is applied to driving a touch screen device. | 08-08-2013 |
