context: Session Reference IE are used to tag the trace record to allow simpler construction of the total record by the entity which combines trace records. If the MDT Configuration IE is included in the CN INVOKE TRACE message and includes the MDT Activation IE set to âImmediate MDT and Traceâ then the RNC shall, if supported, initiate the requested trace function and MDT function as described in TS 32.422 [38]. If the MDT Configuration IE is included in the CN INVOKE TRACE message and includes the MDT Activation IE set to âImmediate MDT Onlyâ or âLogged MDT onlyâ, then the RNC shall, if supported, initiate the requested MDT function as described in TS 32.422 [38] and shall ignore the List of Interfaces to Trace IE and the Trace Depth IE. If Trace Collection Entity IP Address IE is included and if the MDT Configuration IE is also included then the RNC shall, if supported, store the Trace Collection Entity IP address and use it when transferring Trace records, otherwise if MDT Configuration IE
