Methods, devices and computer programs for supporting emergency communications

A method, carried out by an answering point in a network node, for participating in re-establishing an emergency communication between the answering point and a mobile station, the method comprising:

• triggering a transmission, towards the mobile station, of an instruction message, the instruction message including an instruction to start, from the mobile station, a new emergency call towards the answering point without requiring the person who initially established the emergency communication to take any action;
• and
• sending, towards the mobile station, a trigger message associated with the instruction message.

A method, carried out by an intermediate network node between an answering point in a network node and a mobile station, for participating in re-establishing an emergency communication between the answering point and the mobile station, the method comprising:

• receiving, by the intermediate network node, a trigger message from the answering point;
• and
• sending, by the intermediate network node towards the mobile station, an instruction message including an instruction to start, from the mobile station, a new emergency call towards the answering point responsive to the trigger message without requiring the person who initially established the emergency communication to take any action.

A mobile station configured to participate in re-establishing an emergency communication between an answering point in a network node, and the mobile station, the mobile station comprising:

• an instruction message receiver configured to receive an instruction message said instruction message including an instruction to start, from the mobile station, a new emergency call towards the answering point;
• and
• a new emergency communication starter unit, configured to start, from the mobile station, the new emergency call towards the answering point, wherein the new emergency communication starter unit is configured to autonomously start the new emergency call towards the answering point without requiring the person who initially established the emergency communication to take any action.

An answering point in a network node, said answering point configured to participate in re-establishing an emergency communication between the answering point and a mobile station, the answering point comprising:

• a instruction message transmission triggerer unit configured to trigger a transmission, towards the mobile station, of an instruction message, said instruction message including an instruction to start, from the mobile station, a new emergency call towards the answering point without requiring the person who initially established the emergency communication to take any action;
• and
• wherein the instruction message transmission triggerer unit is further configured to send, towards the mobile station, a trigger message associated with the instruction message.

An intermediate network node between a mobile station and an answering point in a network node, said intermediate network node configured to participate in re-establishing an emergency communication between the answering point and the mobile station, said intermediate network node comprising:

• a trigger message receiver configured to receive a trigger message from the answering point;
• and
• a instruction message sender configured to send, towards the mobile station, an instruction message including the instruction to start, from the mobile station, a new emergency call towards the answering point based on the trigger message without requiring the person who initially established the emergency communication to take any action.

A computer program including non-transient computer-readable instructions configured, when executed on a mobile station, to participate in re-establishing an emergency communication between an answering point in a network node and the mobile station, said computer-readable instructions configured to:

• receive an instruction message, said instruction message including an instruction to start, from the mobile station, a new emergency call towards the answering point;
• and
• start, from the mobile station, the new emergency call towards the answering point, wherein the computer readable instructions are configured to autonomously start the new emergency call towards the answering point without requiring the person who initially established the emergency communication to take any action.
