Abstract: A 3GPP LTE protocol enhancement realizes the full benefit of proposed dynamic frequency sharing systems by enhancing current idle mode cell selection mechanisms to support Licensed Shared Access (LSA) cell selection of idle User Equipment (UE) when LSA frequency bands are reclaimed by incumbents. A paging message field, LSAUnavailable is transmitted by Evolved Node Bs for those UEs operating in an idle state. Paging message transmission is repeated for robustness. UEs are also enabled to immediately identify LSA unavailability when a paging message notification of LSA unavailability to idle UEs cannot be transmitted and/or received. A UE comprises a processor and transceiver configured to receive, on a Licensed Shared Access (LSA) frequency band, a paging message notifying the UE of (LSA) frequency band reclamation. The UE performs immediate cell reselection to vacate the reclaimed LSA frequency band and move to the UE operator's licensed primary Long Term Evolution frequency band.

Abstract: An application executing on a device communicates packet data with a server via an operating system (OS) on the device. The device receives information concerning a port mapping policy that specifies a plurality of applications. For each application, a predetermined assignable port space is defined within which an application specific port can be assigned.

The device then translates data packets to be transmitted by the application, such that for a given OS specific source port, the device replaces the OS specific source port field of the packets to be transmitted with the assigned application specific port. The device then transmits the translated data packets with the assigned application specific source port.
