  • Publication number: 20250227673
    Abstract: Methods to overcome Logical Channel ID (LCID) limitations during bearer type switching when multiple ENDC bearers are supported. Initially, the method recites determining a configuration mode of a bearer to be added for the UE, which may be either MCG mode or SCG-split mode. Further, the method recites allocating an LCID to the bearer based on the configuration mode and one or more criteria. The method recites performing, upon detecting an addition of a secondary node in the communication network by checking whether LCIDs are available for allocating corresponding bearers requiring SCG-split mode in response to the addition of the secondary node. The method further recites assigning the LCIDs to the corresponding bearers requiring the SCG-split mode, when the LCIDs are available for the bearers and switching a set of bearers, among the bearers, into the SCG-split mode when the LCIDs are available only for the set of bearers.

  • Publication number: 20240340627
    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.
