Abstract
A method and network monitoring probe for tracking identifiers corresponding to a user device are provided. The probe monitors a source base station (BS) for receipt of at least a first control plane message comprising a first control plane identifier and a first user device identifier; the probe also monitors the source MME for receipt of a second control plane message comprising a second control plane identifier, a second and a third user device identifier; when the first and the second control plane identifiers are identical and the first and the second user device identifiers are identical, the first and third user device identifier are respectively stored or output as an identified first and second user device identifier of the user device, and it is determined that the user device commences a S1-based handover when the first control plane message is determined as a handover required message.
