PROBLEM TO BE SOLVED: To perform data communication with a data size of fixed length or variable length in flow control.SOLUTION: A mobile communication system includes a controller and a base station device. Data communication between the controller and the base station device is performed with a data size of fixed length and a data size of variable length. The controller transmits information indicating whether the data size of data information is fixed length or variable length. The base station device receives the information from the controller.
