Mobile communication system, control device, base station device, system control method and device control method

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.

主权项

1. A control device for a mobile communication system, the control device comprising:
a transmitter which transmits, to a base station device, a first message which includes downlink (DL) Radio Link Control (RLC) Protocol Data Unit (PDU) size format information indicating whether RLC PDU size has a fixed length or a variable length, and a receiver which receives a RADIO LINK RECONFIGURATION FAILURE message from the base station device if, in a new configuration, there exists a priority queue that is set to use variable RLC PDU size and not set to use Maximum Medium Access Control data (MAC-d) PDU Size Extended, wherein the first message initiates a procedure for a synchronized radio link reconfiguration.
