1. A method, comprising: receiving a signaling message in a functional entity for subscriber mobility management in a mobile communication system; receiving a trace command, the trace command identifying at least one subscriber whose signaling messages are to be traced and identifying a tracer to which information obtained during tracing is sent; receiving a start message of a dialogue; in response to receiving the start message, determining whether the dialogue is related to the subscriber to be traced; and in response to determining that the dialogue is related to the subscriber to be traced, adding the dialogue to a list of traced dialogues, where determining that the signaling message is related to the at least one subscriber comprises: determining whether the signaling message belongs to a traced dialogue on the list of traced dialogues; and in response to determining that the signaling message is related to the at least one subscriber, sending, from the functional entity to the tracer, a copy of the signaling message, wherein the copy of the signaling message sent to the tracer is identical to the received signaling message.
