摘要:
Described is a method for managing locally switched call connections in a wireless communication network comprising 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 and 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. Moreover, the method is implemented in a network node, while the method steps can be executed by means of a computer program product comprising instruction sets performing each method step.
