Abstract: Method for discovering handover capabilities of a mobile communication network includes: receiving, by a user equipment, handover capability information from the mobile communication network, wherein the user equipment communicates with a core network using either a first or a second radio access technology; and based on the first radio access technology being used, initiating handover, by the user equipment, from the first to the second radio access technology when the handover capability information indicates a capability of the mobile communication network to support a handover from the first to the second radio access technology; and/or based on the second radio access technology being used, initiating handover, by the user equipment, from the second to the first radio access technology when the handover capability information indicates a capability, of the mobile communication network to support a handover from the second radio access technology to the first radio access technology.

Abstract: A method for handling emergency calls includes: receiving, by a user equipment attached to a mobile communication network, emergency call capability information indicative of whether the mobile communication network supports an emergency service for the user equipment in a case where the user equipment is connected to the mobile communication network via a wireless access point connected to an external packet data network; and initiating, by the user equipment, an emergency call via the wireless access point or via an access network of the mobile communication network different from the wireless access point based on whether or not the emergency call capability information indicates that the mobile communication network supports the emergency service for the user equipment in the case where the user equipment is connected to the mobile communication network via the wireless access point.
