The present invention is a method and apparatus for generating a time synchronization signal. More particularly, the present invention relates to a method and apparatus for generating various types of time synchronization signals.
The time synchronization between the communication devices can be performed through various time synchronization signals. For example, in a wired network, time synchronization between devices is performed using a time synchronization signal such as E1 / T1 / 2M as a synchronization signal suitable for frequency synchronization.
In the wireless network, time synchronization between devices connected to the wireless network is performed through a method using a Global Positioning System (GPS) signal and a Precision Time Protocol (PTP) / Network Time Protocol (NTP) method.
The time synchronization method used in the wired network is not suitable for the use or function of a wireless base station equipment which requires not only frequency synchronization but also phase synchronization. Also, as a method of using the GPS signal as a time synchronization signal, an individual antenna or a GPS signal distribution device should be installed in order to receive GPS signals. However, installing an antenna and installing a GPS signal distribution device involves many difficulties such as additional wiring and lack of space. In addition, the PTP / NTP method requires a separate grand master device to operate, resulting in difficulties in management and cost.

According to various embodiments of the present invention, a method of generating a plurality of time synchronization signals of different forms includes extracting state information of each of a first GPS signal and a second GPS signal received, Setting one of the first GPS signal and the second GPS signal as a reference signal based on the generated reference signal, generating a plurality of clocks and time information synchronized with the set reference signal, and using the plurality of clocks and time information And generating a first time synchronization signal and a second time synchronization signal of different types from each other.
The method and apparatus for generating a time synchronization signal according to various embodiments of the present invention may generate various types of time synchronization signals and supply time synchronizing signals of corresponding types of devices required for time synchronization. In addition, the operator may appropriately change the configuration of the time synchronizing signal generator according to the configuration of the base station equipment.
