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.
