Abstract

A method may comprise receiving, at a server configured in a long term evolution network, information indicative of a condition of utilization of a first radio access technology resource accessible by a user device. If the condition of utilization indicates an adverse network condition, then the server may transmit a change command instructing the user device to migrate to a second radio access technology resource.
