Abstract: front page image
(EN)In a wireless communications system according to the present invention, a second relay wireless terminal (221) is capable of receiving terminal call data from a downstream child wireless terminal (301) immediately after transmitting a beacon signal to said child wireless terminal (301), and, immediately upon receipt of said terminal call data, is capable of transmitting said terminal call data to a first relay wireless terminal (211) immediately after receiving a beacon signal transmitted by said first relay wireless data terminal (211). As a result, large delays in relay transmission of terminal call data are alleviated, allowing prompt wireless communication.
(FR)Dans un système de communication sans fil selon la présente invention, un second terminal de relais sans fil (221) est en mesure de recevoir des données d'appel de terminal provenant d'un terminal sans fil enfant (301) situé en aval, immédiatement après avoir émis un signal de balise vers ledit terminal sans fil enfant (301) et, immédiatement après réception desdites données d'appel de terminal, est en mesure d'émettre lesdites données d'appel de terminal vers un premier terminal de relais sans fil (211) immédiatement après avoir reçu un signal de balise émis par ledit premier terminal de relais sans fil (211). De ce fait, on évite les forts retards dans le relayage des données d'appel de terminal, ce qui permet des communications sans fil rapides.
(JA) 本発明に係る無線通信システムにおいては、第二中継無線端末(221)は、その下位の子無線端末(301)に対してビーコン信号を送信した直後に、当該子無線端末(301)からの端末発呼データを受信することができ、また、端末発呼データを受信してまもなく、第一中継無線端末(211)から送信されるビーコン信号を受信し、その直後に当該第一中継無線端末(211)に端末発呼データを送信することができる。その結果、端末発呼データの中継伝送に大きな遅延が生じることが抑えられ、迅速な無線通信が可能となる。
