Abstract: A security system on a wireless LAN system and a security method thereof are provided to set an encryption key and a certificate on a wireless LAN terminal and a wireless LAN access point without input of a user by managing the encryption key and the certificate with a key management server. In a security system on a wireless LAN system, a key management server(120) stores an encryption key and a certificate for system security. The key management server(120) provides a device with the encryption key and the certificate when the encryption key and the certificate are requested. A wireless LAN terminal(100) requests the corresponding encryption key and certificate to the key management server(120) when the encryption key and the certificate are requested. A wireless LAN access point(110) requests the corresponding encryption key and certificate to the key management server(120) when the encryption key and the certificate are requested.

Abstract: PURPOSE: An apparatus and a method for determining ping interval of an active sync service in a wireless communication system are provided to determine an optimal heartbeat interval rapidly by adjusting the heartbeat interval through the usage of a binary searching method. CONSTITUTION: An HB(Heartbeat Interval) is set up in a preset minimum value(300), and the success of the ping message transmission and reception is sensed(310). If the transmission and reception of the ping message is continuously successful as many as a preset frequency, the HB is changed in the preset maximum value(302). Unless the transmission and reception of the ping message is continuously successful as many as a preset frequency, a push mode for transmitting and receiving the ping message is terminated(304). Through a binary search method, an optimal HB is searched(340).

Abstract: A method of transmitting and receiving video data in a digital broadcasting service and an apparatus thereof are provided to decode only encoded frames when a part of frames among video data of a digital broadcast is encoded and transmitted, thereby restoring a complete image. A data processing unit encodes video data according to the H.264 mode(S401). A code control unit obtains frame information which is information about a kind of a frame among I, B, and P frames(S403). The data processing unit encodes video data according to an RTP protocol(S405). The data processing unit encodes video data according to a protocol in U(S407). The code control unit determines whether a frame of video data is the I frame based on frame information(S409). When the frame of video data is the I frame, the code control unit controls the data processing unit to code a corresponding frame(S411).

Abstract: An apparatus and a method for realtime packet reception are provided to store only the latest data in a socket buffer, thereby transmitting data in a predetermined time and increasing the efficiency of a memory. A method for receiving a socket layer capable of holding the latest data comprises the following steps of: checking whether an SO_LPO(Socket_Latest Packet Only) mode is set up(620); checking data stored before received data whenever data is received in the preset SO_LPO mode; deleting the previously stored data when the previously stored data exists(660); and storing the received data in a socket buffer after deleting the previously stored data.
