Abstract

L'invention concerne un procédé et des agencements, permettant d'exécuter une procédure de radiomessagerie dans un système de communications radio, comprenant un réseau de communications radio, et au moins une première station mobile. Lors de la réception d'une demande d'établissement d'appel avec la première station mobile, le réseau de communications radio lance (201) la procédure de radiomessagerie. Un signal de radiomessagerie est émis (202) vers la première station mobile. Lors de la détection (203) d'une anomalie dans la procédure de radiomessagerie, potentiellement due à des signaux radio émis entre la première station mobile et le réseau de communications radio sujet à une perte de propagation excessive, un signal d'alarme est produit (204) vers l'utilisateur de la première station mobile. Après exécution d'actions de compensation qui tendent à offrir des conditions plus favorables pour une communication radio, l'utilisateur déclenche (205) la première station mobile afin d'émettre (206) un signal manuel de réponse de radiomessagerie vers le réseau de communications radio.
