WIRELESS TERMINAL CALL METHOD AND WIRELESS ACCESS SYSTEM
First Claim
1. A wireless terminal call method in which a plurality of wireless terminals each having a unique ID share a wireless frame including a plurality of wireless slots and a wireless base station calls the wireless terminals using a broadcast slot of the wireless frame, the wireless terminal call method comprising:
- generating, by the wireless base station, a first broadcast signal including parts of wireless terminal IDs of the wireless terminals to be called and a second broadcast signal including information on assignment positions of the wireless slots for the wireless terminals to be called;
generating, by the wireless base station, a wireless frame including the first broadcast signal and the second broadcast signal subsequent to the first broadcast signal in the broadcast slot; and
transmitting, by the wireless base station, the wireless frame to the wireless terminals,receiving, by the wireless terminals, the first broadcast signal transmitted from the wireless base station;
detecting, by the wireless terminals, whether the part of the wireless terminal ID of the own wireless terminal is included in the first broadcast signal received in the broadcast signal reception or not and determining that the second broadcast signal is to be continuously received when the part of the wireless terminal ID is included; and
receiving, by the wireless terminals, the second broadcast signal when it is determined in the broadcast signal determination that the second broadcast signal is to be received, stopping receiving data transmitted from the wireless base station when assignment information to be transmitted to the own wireless terminal is not present in the received second broadcast signal, and receiving data transmitted from the wireless base station to the own wireless terminal based on the information on the assignment position of the wireless slot included in the second broadcast signal when the assignment information to be transmitted to the own wireless terminal is present in the received second broadcast signal.

Abstract
A wireless terminal receives a first broadcast signal transmitted from a wireless base station; detects whether a part of a wireless terminal ID of the own wireless terminal is included in the first broadcast signal received in the broadcast signal reception or not and determines that the second broadcast signal is to be continuously received when the part of the wireless terminal ID is included; and receives the second broadcast signal when it is determined in the broadcast signal determination that the second broadcast signal is to be received, stops receiving data transmitted from the wireless base station when assignment information to be transmitted to the own wireless terminal is not present in the received second broadcast signal, and receives data transmitted from the wireless base station to the own wireless terminal based on the information on the assignment position of the wireless slot included in the second broadcast signal when the assignment information to be transmitted to the own wireless terminal is present in the received second broadcast signal.

8. A wireless access system in which a plurality of wireless terminals each having a unique ID share a wireless frame including a plurality of wireless slots and a wireless base station calls the wireless terminals using a broadcast slot of the wireless frame, wherein the wireless base station comprises:
-
a broadcast signal generation unit which generates a first broadcast signal including parts of wireless terminal IDs of the wireless terminals to be called and a second broadcast signal including information on assignment positions of the wireless slots for the wireless terminals to be called; a wireless frame generation unit which generates a wireless frame including the first broadcast signal and the second broadcast signal subsequent to the first broadcast signal in the broadcast slot; and a first transceiver unit which transmits the wireless frame to the wireless terminals and receives wireless signals transmitted from the wireless terminals, and wherein the wireless terminals comprises; a second transceiver unit which receives the first broadcast signal transmitted from the first transceiver unit and transmits the wireless signal to the wireless base station; a broadcast signal determination unit which detects whether the part of the wireless terminal ID of the own wireless terminal is included in the first broadcast signal received by the second transceiver unit or not and determines that the second broadcast signal is to be continuously received when the part of the wireless terminal ID is included; a broadcast signal reception unit which receives the second broadcast signal subsequent to the first broadcast signal when the broadcast signal determination unit determines that the second broadcast signal is to be received; and a data reception unit which stops receiving data transmitted from the wireless base station when assignment information to be transmitted to the own wireless terminal is not present in the received second broadcast signal, and receives data transmitted from the wireless base station to the own wireless terminal based on information on the assignment position of the wireless slot included in the second broadcast signal when the assignment information to be transmitted to the own wireless terminal is present in the received second broadcast signal.
