(EN) INTERWORKING BETWEEN MOBILE RAILWAY NETWORKS AND GSM NETWORKS
(FR) INTERFONCTIONNEMENT ENTRE DES RÉSEAUX MOBILES POUR VOIES FERRÉES ET DES RÉSEAUX GSM
Abstract
(EN)
A server receives a call request for a mission critical, push to talk (MCPTT) call. In response to receiving the call request, the server accesses a mapping of an MCPTT identifier of a user equipment with an interworking identifier that is formed according to an address format implemented in Global System for Mobile communications (GSM) for Railways (GSM-R). The server then forwards the call request from the server based on the mapping. In some cases, the MCPTT identifier is a uniform resource identifier (URI) and the interworking identifier is represented in an e164 format.
(FR)
Un serveur reçoit une demande d'appel relative à un appel de messagerie instantanée vocale de première importance (MCPTT). En réponse à la réception de la demande d'appel, le serveur accède à une mise en correspondance d'un identifiant MCPTT d'un équipement utilisateur et d'un identifiant d'interfonctionnement qui est formé en fonction d'un format d'adresse utilisé dans le système mondial de communications mobiles (GSM) pour voies ferrées (GSM-R). Puis le serveur transfère la demande d'appel provenant du serveur sur la base de la mise en correspondance. Dans certains cas, l'identifiant MCPTT est un identificateur de ressource uniforme (URI) et l'identifiant d'interfonctionnement est représenté en un format e164.
