8.28 CN Deactivate Trace

25.4133GPPRelease 17TSUTRAN Iu interface Radio Access Network Application Part (RANAP) signalling

8.28.1 General

The purpose of the CN Deactivate Trace procedure is to inform the RNC to stop the trace session, initiated by a signalling based activation, for the indicated trace reference and related to the UE the Iu connection is used for. The procedure uses connection oriented signalling.

8.28.2 Successful Operation

Figure 33: CN Deactivate Trace procedure. Successful operation.

The CN invokes the CN Deactivate Trace procedure by sending a CN DEACTIVATE TRACE message to the UTRAN as defined in TS 32.422 [38].

The CN DEACTIVATE TRACE message shall contain the Trace Reference IE. The RNC shall stop the trace session for the indicated trace reference in the Trace Reference IE. In case of simultaneous CS/PS connections, the trace session for the indicated trace reference shall be closed upon reception of the CN DEACTIVATE TRACE message from any of the CN domain, whether it was the one which initiated trace session activation or not.

8.28.2.1 Successful Operation for GERAN Iu mode

The CN DEACTIVATE TRACE message shall contain the Trace Reference IE and may contain the Trigger ID IE. The Trace Reference IE and, if present, the Trigger ID IE are used to indicate which trace shall be stopped.
