Mobile device and method

摘要

Embodiments of the invention provide the ability to use policy defined by the operator to control the interfaces on which data is sent and received by a device. 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 may define when certain data may be sent or received over a particular interface. Advantageously, the device may receive new policy from the operator in order to help with the operator's own operational objectives. For example, the operator may be engaging in traffic shaping or other traffic limitation, for example to ease congestion or enforce service agreements. To support this a policy which implements corresponding traffic limitation or shaping on the air interface between the mobile device and network base stations can be sent to the mobile device. This will have the effect of reducing signaling congestion on the air-interface.
