Abstract
The present disclosure provides a method (100) in an authentication node for tracing a User Equipment, UE. The method (100) includes: receiving (110) a tracing activation instruction to activate tracing of the UE based on an equipment identifier of the UE; obtaining (120) trace requirement data associated with the UE; receiving (130) from a network node a first signaling message containing the equipment identifier of the UE; and generating (140) a trace record related to the UE based on the trace requirement data in response to receiving the first signaling message.
Claims17
A method performed by an Authentication Server Function, (AUSF) node for tracing a User Equipment (UE) comprising:
- receiving a tracing activation instruction to activate tracing of the UE based on a permanent equipment identifier of the UE;
- obtaining trace requirement data associated with the UE;
- receiving from an Access and Mobility Management Function (AMF) node a first signaling message containing the permanent equipment identifier of the UE;
- and
- generating a trace record related to the UE based on the trace requirement data in response to receiving the first signaling message.
A method performed by an Access and Mobility Management Function (AMF) node for facilitating tracing of a User Equipment (UE) at an Authentication Server Function (AUSF) node, the method comprising:
- transmitting to the AUSF node a UE Authentication Request containing a permanent equipment identifier of the UE, wherein the permanent equipment identifier of the UE facilitates generation by the AUSF node of a trace record related to the UE, based on a tracing activation instruction and trace requirement data.
