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.
