| 20100178922 | Apparatus and method for handover in mobile communication system - An apparatus and method for handover in a mobile communication system enables a Mobile Station (MS) to perform a normal handover without performing an unnecessary handover. A Base Station (BS) apparatus capable of preventing an unnecessary handover includes a handover manager. The handover manager receives handover information, including information about at least one cell through which an MS has passed, from a neighbor cell to determine whether the MS has performed an unnecessary handover. If it is determined that the MS has performed an unnecessary handover, the handover manager notifies the occurrence of the unnecessary handover by the MS to the neighbor cell. | 07-15-2010 |

| 20090086764 | System and method for time synchronization on network - A system and method for time synchronization on a network is provided. According to the system and method for time synchronization, a slave clock device does not continuously receive a time synchronization message periodically transferred from a master clock device and thus does not correct its time upon all such occasions. Rather, the slave clock device requests time information from the master clock device only when the slave clock device needs to correct its time, and receives a time synchronization message transferred from the master clock device and compensates for its time deviation only while the slave clock device is activated, thereby reducing its power consumption and amount of computation. | 04-02-2009 |
