Title
(EN) METHOD AND ARRANGEMENT FOR CELL OUTAGE COMPENSATION IN A COMMUNICATION NETWORK SYSTEM
(FR) PROCÉDÉ ET AGENCEMENT DE COMPENSATION D'INDISPONIBILITÉ DE CELLULE DANS UN SYSTÈME DE RÉSEAU DE COMMUNICATION
Abstract
(EN)
The present invention relates to an arrangement, a communication network node and method for cell outage compensation in a communication network system comprising a plurality of communication network nodes (15a, 15b) communicating with user equipments (18), where each network node (15a, 15b) is serving at least one cell (19a, 19b), in which the user equipments (18) are situated, via two or more reconfigurable physical antennas (15a1, 15a2, 15b1, 15b2) configured according to an initial antenna parameter set. Cell outage is determined in a network node (15b). One of the reconfigurable physical antennas (15a2) of at least one cell (19a) is made temporarily available for compensation. The available antenna (15a2,) is prepared for compensation by reconfiguring one or more antenna parameters thereof in accordance with a compensating antenna parameter set. A new compensating cell (20) is transmitted from the prepared antenna (15a2). Upon cell recovery the compensating cell (20) is removed and the reconfigurable physical antennas (15a2) of the compensating cell (20) returned to the initial antenna parameter set.

La présente invention porte sur un agencement, un nœud de réseau de communication et un procédé de compensation d'indisponibilité de cellule dans un système de réseau de communication comprenant une pluralité de nœuds de réseau de communication (15a, 15b) communiquant avec des équipements utilisateurs (18), chaque nœud de réseau (15a, 15b) desservant au moins une cellule (19a, 19b), dans laquelle les équipements utilisateurs (18) sont situés, par l'intermédiaire de deux antennes physiques reconfigurables ou plus (15a1, 15a2, 15b1, 15b2) configurées conformément à un ensemble de paramètres d'antenne initial. Une indisponibilité de cellule est déterminée dans un nœud de réseau (15b). L'une des antennes physiques reconfigurables (15a2) d'au moins une cellule (19a) est rendue temporairement disponible pour une compensation. L'antenne disponible (15a2) est préparée pour une compensation par reconfiguration d'un ou plusieurs de ses paramètres d'antenne conformément à un ensemble de paramètres d'antenne de compensation. Une nouvelle cellule de compensation (20) est émise par l'antenne préparée (15a2). Lors d'un rétablissement de cellule, la cellule de compensation (20) est supprimée et les antennes physiques reconfigurables (15a2) de la cellule de compensation (20) sont renvoyées à l'ensemble de paramètres d'antenne initial.
