Abstract
Systems, methods and a mobile device for using policy defined by the operator to control the interfaces on which data is sent and received by the device are provided. The policy can be dynamically updated by the operator, by pushing new policy to the device for implementation. The policy can define that the device should switch certain data between two or more available interfaces at certain times, or when certain data may be sent or received over a particular interface. The device may receive new policy from the operator in order to help with the operator's own operational objectives, such as traffic shaping or other traffic limitation to ease congestion or enforce service agreements. A policy implementing corresponding traffic limitation or shaping on the air interface between the mobile device and network base stations can be sent to the mobile device so as to reduce signaling congestion on the air-interface.
