Abstract
There is provided a base station device capable of achieving synchronization in a wired manner between base station devices in IP-DECT. Thus, according to the base station device, in slave base station devices, synchronization control unit hardware that is connected to Ethernet (registered trademark), and outputs timestamp information and synchronization pulses which includes interval pulses and wide pulses, synchronization control unit software that generates frame numbers based on the timestamp information, and a wireless timing control unit that receives the synchronization pulses generated in the synchronization control unit hardware and the frame numbers generated in the synchronization control unit software, and performs timing control for performing wireless communication with IP-DECT client terminals are provided. The wireless timing control unit includes a frame counter, and the frame counter is updated using the frame numbers with the wide pulses as triggers.
