METHODS AND APPARATUSES IN COMMUNICATION SYSTEMS

摘要

The present invention relates to a method in a legacy access node for selecting a suitable RAN, of a plurality of RANs for a LTE UE, capable of both PS and CS sessions in a global communication network, The method comprises the steps of connecting the UE to a legacy RAN via a radio interface module and then establishing a PS session with the connected UE. The bandwidth that the UE currently is consuming is monitored and compared with a predefined bandwidth threshold. If the consumed bandwidth exceeds the predefined bandwidth threshold an attempt will he made to trigger transferring of the UE from the current legacy RAN to the LTE RAN. The present invention also relates to a corresponding method in a eNodeB where the attempt to trigger transferring of the UE from the LTE RAN to the legacy RAN is made if the consumed bandwidth falls below the predefined threshold. The invention further relates to a legacy access node and an eNodeB adapted and configured to perform the methods.
