摘要： A method and apparatus for time synchronization (TS) method using GPS information in a communication system synchronizing the time of slave nodes, which do not have a GPS receiver, by using GPS information of a node having a GPS receiver. The method includes the steps of extracting 1PPS, TOD, 1PPS_en, and clocks using GPS signals by a grand master node having a GPS receiver, stabilizing the signals, generating a sync message for TS, and transmitting the sync message to a slave node; receiving the sync message by the slave node and conducting a TS operation using OFCC synchronization technology extracting 1PPS, TOD, and 1PPS_en signals using the modified TOD information by the block and delivering to a stabilization block of the slave node for stabilization; and redelivering to the TS block to update TOD information and generate a sync message for TS of a second slave node.

摘要： A method for reducing power consumption in a portable radio communication terminal by selectively preventing back light operation using daylight hours. The portable radio communication terminal checks whether current time of the timer is within a predetermined period of daytime. If the current time is within the period of daytime, the portable radio communication terminal is set to a back light-off mode. In this condition, if key data is received, the portable radio communication terminal manages the key data without turning on the back light. Therefore, it is possible not only to extend an operating time of the battery but also to prevent an increase of the temperature due to the heat radiation of the portable radio communication terminal.
摘要翻译：一种通过选择性地防止使用白天的背光操作来降低便携式无线电通信终端中的功耗的方法。便携式无线电通信终端检查定时器的当前时间是否在白天的预定时段内。如果当前时间在白天的时间段内，便携式无线电通信终端被设置为背光照射模式。在这种情况下，如果接收到密钥数据，便携式无线电通信终端在不打开背光的情况下管理密钥数据。因此，不仅可以延长电池的工作时间，而且可以防止便携式无线通信终端的热辐射导致的温度上升。
