  • Patent number: 8352844
    Abstract: A method and apparatus for transmitting control information in a wireless communication system using a Low Density Parity Check (LDPC) code is provided. The number of LDPC blocks, through which L1 post-signaling information is to be transmitted, is determined according to the total number of bits of the L1 post-signaling information. The number of input information bits of each LDPC block is calculated when the determined number of LDPC blocks is plural. The number of puncturing bits among parity bits of each LDPC block is determined considering a modulation order. A frame including one or multiple LDPC blocks generated through the preceding steps is transmitted.

  • Patent number: 8350671
    Abstract: Provided is a method and an apparatus for controlling a NEW MESSAGE alert in a portable wireless terminal. In a sender-side terminal, a NEW MESSAGE alert is set after a message is written. The NEW MESSAGE alert setting is designated at a header of the message. The message having the header with the NEW MESSAGE alert setting is transmitted. In a receiver-side terminal, a message is received and it is determined whether a NEW MESSAGE alert is designated at a header of the received message. If a NEW MESSAGE alert is designated at the header of the received message, the designated NEW MESSAGE alert is generated. Therefore, both a sending user and a receiving user can have equal authority over the NEW MESSAGE alert.

  • Patent number: 8345626
    Abstract: Provided is a function of minimizing a delay time of a packet call disconnect due to a handover between communication networks providing a communication service using different mobile communication technologies. To do this, even though a handover situation is generated during a packet service, the packet service is continuously provided by maintaining a current mode and performing a mode change after registration in a handover target network succeeds. Accordingly, since the packet service is not provided only while a packet call connecting process is performed, a delay time according to a packet call reconnection can be minimized.
