Abstract
PROBLEM TO BE SOLVED: To provide a method and a base station sub-system that manage local switching call connection in a radio communication network.
SOLUTION: A method includes the steps of: receiving by a core network node 118 a first message indicating that a target radio access node 108 has detected a first user device 102 connected by local switching call connection; and transmitting triggered by the first message a second message to request a state change of local switching call connection to a second user device 104 so as to change a user plane data path 100 from the first user device 102 to the second user device 104 to a core network path 109.
