Abstract

La présente invention concerne une technologie de communications, et en particulier, à un dispositif et à un procédé d'implémentation de réception/transmission de points multiples coordonnés, qui sont utilisés pour déclencher un transmission/réception de points multiples coordonnés au bon moment. Le procédé de l'invention est que : dans les modes de réalisation de la présente invention, un côté réseau utilise un résultat de rapport de terminal sur la base d'une mesure d'événement A3 en tant que fondation de détermination de déclenchement de réception/transmission de points multiples coordonnés. Par conséquent, le côté réseau peut détecter avec précision si un terminal arrive au niveau du bord d'une cellule et détecte que le terminal est situé dans des zones de chevauchement constituées de cellules, de sorte qu'une réception/transmission de points multiples coordonnés peut être déclenchée à temps au bon moment, en outre une qualité de transmission de données du terminal peut être assurée, et par ailleurs une qualité de service d'un système peut être efficacement assurée. De plus, la solution peut satisfaire les protocoles existants et un côté terminal n'a pas besoin d'être trop modifié, ce qui permet d'économiser un grand nombre de coûts de développement et de maintenance.
