Parameter Description

PURPOSE The purpose for using Event A5. Not in current use. The definition is made for later use.

ci_A5PurposeIntraLteHandover: Intra-LTE handover.

ci_A5PurposeSpare_1: Reserved.

ci_A5PurposeSpare_2: Reserved.

ACTIVE_STATE Whether to use the Event A5.

Inactive: Event A5 is not used.

Active: Event A5 is used.

A5_THRESHOLD1_RSRP RSRP threshold1 used for triggering the EUTRA measurement report for Event A5.

A5_THRESHOLD2_RSRP RSRP threshold2 used for triggering the EUTRA measurement report for Event A5.

TIME_TO_TRIGGER timeToTrigger value for Event A5. The time-ToTrigger value is the period of time that must be met for the UE to trigger a measurement report.

TRIGGER_QUANTITY This parameter is used to set up the TriggerQuantity of Event A5 during ReportConfigEutra configuration. The triggerQuantity can be set to rsrp/rsrq/followA2Event. The UE transmits Event A5 when RSRP or RSRQ meets a specific threshold according to triggerQuantity. If the triggerQuantity is RSRP, the A5_THRESHOLD_RSRP is used. If it is RSRQ, the

A5_THRESHOLD_RSRQ is used. If the triggerQuantity is followA2Event, It will

Parameter Description

followA2Event: The trigger quantity of this event follows the trigger quantity of the previously received A2 event.

Parameter Description

NO_X2 Whether to make X2 connection to neighbor eNB.

False: X2 connection to neighbor eNB is made.

True: X2 connection to neighbor eNB is not made.

NO_HO Whether to perform handover to the neighbor eNB.

False: Handover to neighbor eNB is performed.

True: Handover to neighbor eNB is not performed.
