Hello, @Unicef!
You can refer to the following information.
Indicates whether to enable eNodeB-triggered MME load rebalancing. When this parameter is set to ON(On), the eNodeB releases the RRC connection for a UE with the cause value 'loadBalancingTAUrequired' if the UE accesses the cell using an S-TMSI that is associated with an overloaded MME. This ensures that the UE can be routed to a lightly loaded MME if it initiates another access request. When this parameter is set to OFF(Off), the eNodeB sends an RRCConnectionRelease message with the cause value 'other' to the UE to release its RRC connection.
Thanks!
