BASE STATION CONTROL METHOD FOR CONNECTION OF TERMINAL WITH HIGHER PRIORITY AND BASE STATION SUPPORTING THE SAME
First Claim
1. A method of controlling a base station that provides service to a first terminal and a second terminal having higher priority than the first terminal, the method comprising:
- determining whether there is an influx of call connection attempts when the first terminal and the second terminal perform initial ranging;
if it is determined that there is an influx of call connection attempts, setting a initial ranging backoff window size included in an information element of S-SFH SP3 (Secondary-Superframe Header SubPacket3) to a first size; and
if it is determined that there is an influx of call connection attempts, setting a initial ranging backoff window size for the second terminal in an AAI-SCD (Advanced Air Interface-System Configuration Descriptor) message to a second size.

Abstract
A method of controlling a base station is disclosed that provides service to a first terminal and a second terminal having higher priority than the first terminal. The base station determines whether there is an influx of call connection attempts when the lower-priority terminal and the higher-priority terminal perform ranging. If it is determined that there is an influx of call connection attempts, the base station sets the initial ranging backoff window size included in an information element of S-SFH SP3 (Secondary-Superframe Header SubPacket3) to a first size. If it is determined that there is an influx of call connection attempts, the base station sets the initial ranging backoff window size for the second terminal in an AAI-SCD (Advanced Air Interface-System Configuration Descriptor) message to a second size. Accordingly, it is possible to achieve a high probability of success of initial ranging of a higher-priority terminal.

9. A base station comprising:
-
a radio frequency module; and a processor connected with the radio frequency module, and providing service to a first terminal and a second terminal having higher priority than the first terminal, wherein if it is determined that there is an influx of call connection attempts when the first terminal and the second terminal perform initial ranging the processor sets a initial ranging backoff window size included in an information element of S-SFH SP3 (Secondary-Superframe Header SubPacket3) to a first size and a initial ranging backoff window size for the second terminal in an AAI-SCD (Advanced Air Interface-System Configuration Descriptor) message to a second size. - View Dependent Claims (10, 11)

12. A method in which a second terminal having higher priority than a first terminal, among sub-terminals of a base station, is connected to the base station, the method comprising:
-
performing initial ranging with the base station; receiving from the base station an AAI-SCD (Advanced Air Interface-System Configuration Descriptor) message including a first initial ranging backoff window size, which is smaller than a initial ranging backoff window size for the first terminal; and performing initial ranging again with the base station by using the first initial ranging backoff window size. - View Dependent Claims (13, 14)
