8.3.14 Dedicated Measurement Failure

25.4233GPPRelease 17TSUTRAN Iur interface Radio Network Subsystem Application Part (RNSAP) signalling

8.3.14.1 General

This procedure is used by the DRNS to notify the SRNS that a measurement previously requested by the Dedicated Measurement Initiation procedure can no longer be reported. When partial reporting is allowed and supported, this procedure shall be used to report that measurement for one or more RL/RLS can no longer be reported.

This procedure shall use the signalling bearer connection for the relevant UE Context.

The DRNC may initiate the Dedicated Measurement Failure procedure at any time after establishing a Radio Link.

8.3.14.2 Successful Operation

Figure 24: Dedicated Measurement Failure procedure, Successful Operation

This procedure is initiated with a DEDICATED MEASUREMENT FAILURE INDICATION message, sent from the DRNC to the SRNC, to inform the SRNC that a previously requested dedicated measurement can no longer be reported. The DRNC has locally terminated the indicated measurement. The DRNC shall include in the DEDICATED MEASUREMENT FAILURE INDICATION message the reason for the failure in the Cause IE.

The DRNS shall include Unsuccessful RL Information IE or the Unsuccessful RL Set Information IE for the concerned RL or RLS if partial reporting is allowed and it is supported. The DRNS shall include the Individual Cause IE set to an appropriate value if it differs from the value of the Cause IE.

Typical cause values are:

Miscellaneous Causes:

– Control Processing Overload;

– HW Failure;

– O&M Intervention.
