Abstract: A method for controlling a maximum number of Random Access (RA) preambles for a network node to handle concurrently in a first cell in a wireless communications network. A runtime parameter associated with the network node restricts the network node to handle at most a first maximum number of RA preambles concurrently. The network node monitors load characteristics associated with the first cell. When the load characteristics fulfil a triggering condition, the network node selects a second maximum number of RA preambles to be handled concurrently. The second maximum number is selected such that a probability value fulfils a threshold. The probability value is associated with a probability that RA preambles that are to be concurrently transmitted in the first cell will exceed the second maximum number of RA preambles. The runtime is adjusted to restrict the network node to handle at most the second maximum number of RA preambles concurrently.

Abstract: A radio access network (RAN) manages resources associated with a user equipment (UE) operating in dual connectivity (DC) with a master node (MN) and a secondary node (SN) in accordance with an initial configuration of a radio connection between the UE and the RAN (1102).

Abstract: A method for steering communication traffic of a user equipment (UE) in a network includes network entities that are configured to provide a radio access network for the user equipment. A serving network entity provides a current access to the network for the UE. Each network entity communicates with neighboring network entities. An algorithm implemented on a network unit uses as input a first time duration (Tcell), when the UE is within a radio coverage of the serving network entity, and a second time duration (TLC) that is time taken by the network to determine an adjusted load control setting. If Tcell>TLC the algorithm applies load control procedures within the communication network, and transmits a Radio Resource Control message with a network-calculated load control information to the UE. Otherwise, the algorithm transmits a Radio Resource Control message without the network-calculated load control information to the UE.
