One method includes receiving a request for a mission critical (MC) user profile of a user migrating between a primary mission critical (MC) system and a partner mission critical (MC) system, retrieving the mission critical (MC) user profile for the migrating mission critical (MC) user, collecting one or more ongoing calls having the migrating mission critical (MC) user as a participant at the primary mission critical (MC) system, and transmitting, to the partner mission critical (MC) system, information or identifiers of the one or more ongoing calls that the migrating mission critical (MC) user is a participant.

Un procédé comprend la réception d'une demande d'un profil d'utilisateur critique de mission (MC) d'un utilisateur migrant entre un système critique de mission (MC) primaire et un système critique de mission (MC) partenaire, la récupération du profil d'utilisateur critique de mission (MC) pour l'utilisateur critique de mission (MC) migrant, la collecte d'un ou plusieurs appels en cours ayant l'utilisateur critique de mission (MC) migrant en tant que participant au système critique de mission (MC) primaire, et la transmission, au système critique de mission (MC) partenaire, d'informations ou d'identifiants du ou des appels en cours dont l'utilisateur critique de mission (MC) migrant est un participant.
