Abstract
(DE)
Die Erfindung bezieht sich auf ein Verfahren zum Ansteuern einer Antennenanordnung (AN) eines Funk-Kommunikationssystems, bei dem der Sendebereich (R) der Antennenanordnung (AN) in Sektore (A, B, C, D) unterteilt ist und - die Antennenanordnung (A-D) derart angesteuert wird, dass ein Signal in zumindest einen ersten Sektor gerichtet ausgesendet wird, in dessen Empfangsbereich sich eine empfangende Station (MS) für das Signal befindet, - wobei bei Annäherung, Eintritt oder Aufenthalt der empfangenden Station (MS) an/in einem dem ersten Sektor (D) benachbarten zweiten Sektor (C) die Ansteuerung der Antennenanordnung (AN) zum Aussenden des Signals in den zweiten Sektor (C) durchgeführt wird. Zum Vermeiden des Ansteuerns einer Rundfunk-Antenne (BCAN) bei nicht ausreichendem Empfang der empfangenden Station (MS) in einem der Sektoren (A - D) oder nicht möglicher ausreichender Zuordnung der empfangenden Station (MS) zu einem der Sektoren (A - D) wird vorgeschlagen, dass die angesteuerten Sektoren (A, B, C) alternierend angesteuert werden, so dass zwischen den zumindest zwei Sektoren (B, C) hin- und hergeschaltet wird.
(EN)
The invention relates to a method for activating an antenna assembly (AN) of a radio communications system, the transmission range (R) of said assembly (AN) being subdivided into sectors (A, B, C, D). According to said method: the antenna assembly (A - D) is activated in such a way that a signal is emitted in a targeted manner in at least one sector, the receiving zone of the latter containing a receiving station (MS) for said signal; if the receiving station (MS) approaches, enters or stays in a second sector (C) that is adjacent to the first sector (D), the antenna assembly (AN) is activated to emit the signal in the second sector (C). The aim of the invention is to prevent the activation of a broadcast antenna (BCAN) if the reception of the receiving station (MS) is inadequate in one of the sectors (A - D), or if an adequate allocation of the receiving station (MS) to one of the sectors (A - D) is impossible. To achieve this, the activated sectors (A, B, C) are activated alternately so that a switch back and forth between at least two sectors (B, C) occurs.
(FR)
L'invention concerne un procédé d'excitation d'un réseau d'antennes (AN) d'un système de radiocommunication. Dans ce système, la portée d'émission (R) de ce réseau d'antennes (AN) est sectionnée en secteurs (A, B, C, D) ; ce réseau d'antennes (A-D) est excité, de sorte qu'un signal est émis de façon dirigée dans au moins un premier secteur qui présente une zone de réception dans laquelle se trouve une station réceptrice (MS) pour ce signal, et ledit réseau d'antennes (AN) est excité pour émettre ce signal dans un deuxième secteur (C) adjacent au premier secteur (D), lorsque la station réceptrice (MS) s'approche de ce deuxième secteur (C), entre ou s'arrête dans ce dernier. L'objectif de cette invention est d'éviter l'excitation d'une antenne radio (BCAN) lorsque la réception de la station réceptrice (MS) dans un des secteurs (A - D) n'est pas satisfaisante ou lorsque l'affectation adéquate de cette station réceptrice (MS) à un des secteurs (A - D) n'est pas possible. A cet effet, les secteurs excités (A, B, C) sont excités de façon alternée dans un mouvement de va-et-vient entre au moins deux secteurs (B, C).
