Claim:
A method for managing locally switched call connections in a wireless communication network, comprising the steps: receiving, at a core network node, a first message indicating that a first user equipment connected via the locally switched call connection has been detected in a target radio access node; transmitting, triggered by the first message, a second message requesting a status change of the locally switched call connection to a second user equipment, such that a user plane data path from the first user equipment to the second user equipment is switched to a core network path, wherein the second message comprises a local call local switching status change request, LCLS-Status-Change-Request; receiving, at the core network node, a fourth message indicating that the first user equipment has completed the handover and that the call connection between the handed over first user equipment and the second user equipment cannot be locally switched; and transmitting, in response to the fourth message, a fifth message instructing the clearing of the locally switched call connection between the first user equipment and the second user equipment, after handover of the first user equipment has been completed.
