Method for implementing system information broadcasting function in asynchronous mobile communication system

A method for implementing a system information broadcasting function in an asynchronous mobile communication system, comprising:

• (a) receiving a system information renewal message from a radio network controller, and storing Radio Resource Controller System Information Messages (RSIMs) generated by information block segments and scheduling parameters contained in the message;
• (b) calculating transmission time points of the RSIMs to the air, and forming a queue of the RSIMs based on the calculated transmission time points of the RSIMs according to a set queuing algorithm;
• (c) selecting a first element from the queue of the RSIMs at fixed time intervals;
• and
• (d) transmitting the RSIM to the air when the transmission time point of the RSIM, the selected first element, is the same as the current time point.

An asynchronous mobile communication system comprising:

• a first signal processing part for processing a system update message received from a radio network controller;
• a memory for storing Radio Resource Controller System Information Messages (RSIMs) generated by information block segments and scheduling parameters contained in the processed message;
• a control part for calculating transmission time points of the RSIMs to the air in advance, and forming a queue of the stored RSIMs in an order from the earliest transmission to the air based on the calculated transmission time points;
• a comparing part for comparing the current time point to the transmission time point of the RSIM to be transmitted at the earliest among the queue of the RSIMs at preset intervals under the control of a control signal;
• and
• a second signal processing part for processing the RSIM to be transmitted to the air according to a result of the comparison.
