Abstract

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.
