Abstract

A UE reports an ECGI of a target eNB/gNB missing an X2/Xn interface to a source eNB/gNB. The source eNB/gNB sends a configuration transfer message to a network element to get the X2/Xn interface TNLA of the target eNB/gNB. The source eNB/gNB initiates an initial backoff timer and an exponential backoff multiplier. The source eNB/gNB determines whether the TNLA discovery procedure time is equal to or greater than a current backoff time, the current backoff time being equal to a previous backoff period multiplied by the exponential backoff multiplier. The source eNB/gNB may resend the configuration transfer message to the network element when a previous TNLA discovery procedure time for the same ECGI is equal to or greater than the current backoff time, and not resend the configuration transfer message to the network element when the previous TNLA discovery procedure time is less than the current backoff time.
