Abstract:
1. A method of activating a recording of events relating to a radio communication in a radiocommunication system, comprising: a) receiving a trace activation request at a radio network controller of the radiocommunication system, the trace activation request including a coded list of terminal identifiers associated with corresponding subscribers or system elements for which traces of radio communications are desired and parameters relating to trace implementation procedures, wherein the parameters include at least one of a recording duration to be observed in conjunction with subsequent traces of radio communications and a list of system elements associated with at least a portion of a coverage area for the radio network controller for which radio communications become the subject of the subsequent traces; b) transmitting the coded list of terminal identifiers to a network node in a core network of the radiocommunication system; c) receiving a trace activation instruction at the radio network controller in response to decoding of the coded list of terminal identifiers by the network node and the network node detecting a radio communication associated with a terminal identifier from the decoded list of terminal identifiers and a corresponding subscriber or system element interfacing with the radio network controller; and d) starting a recording of events relating to the detected radio communication and the corresponding subscriber or system element, wherein the parameters relating to trace implementation procedures received in a) are observed in conjunction with the recording.
