A network management system and a method of automatic adjustment for a virtualized base station are provided. The method includes following steps. A user equipment (UE) information table is queried from a core network, and a first reserved resource of a first virtualized base station is queried, where the UE information table includes first location information and a first resource requirement corresponding to a first UE set. A second resource requirement corresponding to a second UE set is obtained from the UE information table based on the first location information and a default range. Whether the first reserved resource matches the second resource requirement is determined to generate a determination result. The first reserved resource of the first virtualized base station is expanded or reduced based on the determination result.

Network management system and method of automatic adjustment for virtualized base station

A communication system, a base station, a user equipment (UE), and a timing synchronization method for the base station thereof are provided. The communication system includes a first base station, a second base station and the user equipment. The UE is located within coverage of the first base station and the second base station. The first base station and the second base station respectively measure signal stability of the user equipment so that the second base station selects the user equipment based on the measurements for the stability of the signals. The first base station computes a first timing error for transmitting or receiving message between the first base station and the user equipment then transmits the first timing error to the second base station. The second base station adjusts a timing difference between the first base station and the second base station through the first timing error.
