摘要

The invention relates to a method for improved handling of emergency calls of a user equipment being connected to a wireless access point while initiating an emergency call, wherein the user equipment is connected to a mobile communication network via wireless access point that is connected to an external packet data network, the mobile communication network comprising a core network and a radio access network, wherein the method comprises either a first and a second step, or a third step:
-- in the first step, the user equipment - while being attached to the mobile communication network - receives an emergency call capability information, the emergency call capability information being indicative of the mobile communication network providing the possibility of an emergency service towards the user equipment via a wireless access point,
-- in the second step and in case that an emergency call needs to be initiated by the user equipment while the user equipment (20) is attached to the mobile communication network (100) via the wireless access point, the user equipment initiates the emergency call via the wireless access point in case that the emergency call capability information indicates that the mobile communication network provides the possibility of an emergency service towards the user equipment via a wireless access point, and the user equipment initiates the emergency call using a different access network of the mobile communication network in case that the emergency call capability information indicates that the mobile communication network is unable to provide the possibility of an emergency service towards the user equipment via a wireless access point
-- in the third step and in case that an emergency call needs to be initiated by the user equipment while the user equipment is attached to the mobile communication network via the wireless access point, the user equipment initiates the emergency call using an access network of the mobile communication network different from the wireless access point in case that no emergency call capability information is received by the user equipment.
