Abstract
A target Access and Mobility Management Function (AMF) switches the path for network traffic to a User Equipment (UE) in an inter-AMF mobility event. The target AMF obtains a path switch request from a target next generation Node B (gNB). The path switch request includes a UE identifier and a source AMF identifier. The target AMF compares the source AMF identifier with a target AMF identifier, and responsive to a determination that the source AMF identifier is different than the target AMF identifier, the target AMF provides a UE context transfer request to the source AMF. The target AMF obtains the UE context from the source AMF and processes the path switch request to update a core network path for a session of the UE. The target AMF also provides a path switch response to the target gNB.
