Abstract: L'invention concerne un procédé d'acheminement d'un message court prioritaire ou non prioritaire d'un centre de service jusqu'à une station mobile d'un réseau mobile terrestre public fournissant à la fois un service de transmission par paquets de données et un service avec commutation de circuits. Selon ce procédé, on choisit à l'avance si le message court doit être reçu par la station mobile via un des services en particulier ou l'un quelconque des services. En fonction de ce choix, de la priorité du message court envoyé depuis un centre de service, et d'une indication précisant si la station mobile peut être jointe par l'un, les deux ou aucun des services, on sélectionne une voie d'acheminement via l'un des services, une voie d'acheminement via les deux services ou aucune voie d'acheminement. Si une voie d'acheminement via l'un des services est sélectionnée, le message court est acheminé en conformité avec l'acheminement sélectionné. Si une voie d'acheminement via les deux services est sélectionnée, la voie d'acheminement via le service ayant la préférence la plus élevée par rapport à l'autre service est sélectionnée, et le message court est acheminé en conformité avec la voie d'acheminement via ce service ayant la préférence la plus élevée. Si l'acheminement du message court jusqu'à la station mobile échoue par la voie d'acheminement via le service ayant la préférence la plus élevée, le message court est acheminé en conformité avec la voie d'acheminement par l'autre service ayant la préférence la moins élevée.
