name: IMEI-TAC
full_form: IMEI Type Allocation Code
context: UE measurements activation extends the EPC trace activation procedure, as described in .10. When a Trace Session is activated, configuration parameters of MDT are added into the message. For IMSI/IMEI(SV)/IMEI-TAC based UE selection, or IMSI/IMEI(SV)/IMEI-TAC combined with geographical area based UE selection, UE performance measurements activation request is propagated to UE finally. This mechanism works for the following input parameters: - IMSI only or - IMSI and area information or - IMEI(SV) only or - IMEI(SV) and area information or - IMEI-TAC only or - IMEI-TAC and area information After the IMSI, IMEISV or IMEI-TAC type user attached to the network, the MME shall forward the MDT configurations to the corresponding eNB which serves the IMSI, IMEISV or IMEI-TAC type user. If the area criterion is specified and is not satisfied, the MME shall keep the MDT configuration first and then forward it to the serving eNB only when the area criterion is satisfied. MDT criteria checking on
description: IMEI-TAC (IMEI Type Allocation Code) is a parameter used for UE selection based on device identification, specifically in conjunction with IMSI and geographical area information. It plays a role in the configuration of MDT (Minimization of Drive Tests) measurements activation.
explanation: The context explicitly mentions IMEI-TAC as an input parameter for UE performance measurements activation, alongside IMSI and area information. This indicates that IMEI-TAC is used as a critical attribute for network operation, fitting the definition of a Parameter.
