MOBILE COMMUNICATION SYSTEM, CONTROL DEVICE, BASE STATION DEVICE, SYSTEM CONTROL METHOD AND DEVICE CONTROL METHOD FOR DATA COMMUNICATION USING FIXED OR VARIABLE LENGTH DATA SIZE

摘要

A mobile communication system includes a control device and a base station device. Data communication between the control device and the base station device is conducted using a fixed-length data size and a variable-length data size. The control device transmits information indicating whether a data size of the data communication has a fixed length or a variable length. The base station device receives the information from the control device.
