(FR) GARANTIE DE QUALITÉ DE SERVICE DE POSITIONNEMENT PENDANT DES CHANGEMENTS DE CELLULES
Abstract
(EN)
Methods in a radio network node for assisting a positioning node during positioning of a target wireless device, wherein said positioning is based on radio measurements of uplink radio signals transmitted by the target wireless device, are disclosed. Corresponding radio network node apparatus are also described. An example method begins with detecting (210), at the radio network node, a cell change for the target wireless device. In response to the detected cell change, the radio network node selectively informs (230) a positioning node of the cell change. In some embodiments, the radio network node informs the positioning node only when there is a change in the transmission configuration in at least one cell or when measurements of the uplink radio signals cannot continue.

L'invention concerne des procédés dans un nœud de réseau radio en vue d'aider un nœud de positionnement pendant le positionnement d'un dispositif sans fil cible, ledit positionnement étant basé sur des mesures radio des signaux radio de liaison montante transmis par le dispositif sans fil cible. L'invention concerne également un appareil de nœud de réseau radio correspondant. Un procédé à titre d'exemple débute avec la détection (210), au niveau du nœud de réseau radio, d'un changement de cellule pour le dispositif sans fil cible. En réponse au changement de cellule détecté, le nœud de réseau radio informe sélectivement (230) un nœud de positionnement du changement de cellule. Dans certains modes de réalisation, le nœud de réseau radio informe le nœud de positionnement seulement lorsqu'il existe un changement dans la configuration de transmission dans au moins une cellule ou lorsque les mesures des signaux radio de liaison montante ne peuvent pas se poursuivre.
