Method for implementing system information broadcasting function in asynchronous mobile communication system
First Claim
1. A method for implementing a system information broadcasting function in an asynchronous mobile communication system, comprising:
- (a) storing Radio resource controller System Information Messages (RSIMs) generated by information block segments from a radio network controller in a memory;
(b) calculating transmission time points of the RSIMs to the air;
(c) queuing the stored RSIMs in an order of transmission based on the calculated transmission time points with reference to a current time point;
(d) comparing the current time point with the transmission time point of the RSIM to be transmitted earliest in the queued RSIMs at preset time intervals; and
(e) transmitting the RSIMs to the air if the current time point and the transmission time point of the RSIM are the same as a result of the comparison.

Abstract
Asynchronous mobile communication system, and method for implementing a system information broadcasting function in an asynchronous mobile communication system. Upon reception of a system information renewal message from a radio network controller, a base station stores RSIMs generated by all information block segments and scheduling parameters in the message, and then calculates a first transmission time point of each of RSIMs. The base station then forms a queue of the RSIMs according to a queuing algorithm set for the RSIMs. At the end, the base station transmits the RSIM to the air when the transmission time point of a first element of the queue is the same with the current time point at every 20 ms intervals. Therefore, the processing time and the use of memory in the channel card of the base station can be optimized.
