Methods, devices and computer programs for supporting emergency communications

摘要

A network node (4), referred to as answering point (4), performs a method including a triggering procedure (s22) for triggering the transmission, towards a mobile station (2), of an instruction message (12a) including an instruction to start a new emergency communication towards the answering point (4). The triggering procedure (s22) includes sending (s226), towards the mobile station (2), a trigger message (12b). The mobile station (2) performs a method including a receiving procedure (s28) and a starting procedure (s30). The receiving procedure (s28) includes receiving the instruction message (12a) including the instruction to start a new emergency communication towards the answering point (4), and the starting procedure (s30) includes starting a new emergency communication towards the answering point (4). This enables to re-establish an emergency communication between the answering point (4) and the mobile station (2). The invention also relates to network nodes, mobile stations and computer programs.

主权项

1. A method, carried out by a mobile station, for participating in re-establishing an emergency communication between an answering point in a network node, and the mobile station, the method comprising:
receiving an instruction message, said instruction message including an instruction to start, from the mobile station, a new emergency call towards the answering point; and starting, from the mobile station, the new emergency call towards the answering point, wherein starting the new emergency call comprises autonomously starting the new emergency call towards the answering point without requiring the person who initially established the emergency communication to take any action.
