Embodiment Construction

[0059] The present invention will now be described in conjunction with specific embodiments. These specific examples are provided to provide a better understanding to the skilled person, but are not intended to limit the scope of the present invention defined by the appended claims in any way.

[0060] figure 1The method involving answering point 4 and mobile station 2 in one embodiment of the invention is schematically shown. Mobile station 2 may be, but is not limited to, an in-vehicle system (IVS). The answering point 4 is a network node, which can be, but not limited to: a public safety answering point (PSAP) or a third party service center (TSPC). The mobile station 2 or mobile terminal comprises a radio interface. In this sense, although the mobile station 2 may be temporarily stationary, ie in a fixed position, the mobile station 2 has the ability to move.

[0061] After the emergency communication has been established between the mobile station 2 and the answering ...

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.

Description

[0001] title [0002] Method, device and computer program for supporting emergency communications technical field [0003] The present invention relates to methods, devices and computer programs for supporting emergency communications. This primarily includes support for establishing emergency communications from a mobile station, eg, located or integrated into a vehicle, to a Public Safety Answering Point (PSAP) or Third Party Service Center (TPSC). Background technique [0004] The establishment of emergency communications constitutes an important step in the effective delivery of emergency services, including police services, fire and rescue services, and emergency medical services. For example, establishing emergency communications may be paramount to providing emergency medical care after a car accident. In order to reduce the time required for rescue teams to reach the site of a car accident, it has been envisaged to provide a system in which emergency communication ...
