Abstract: A policy server (e.g., Policy and Charging Rules Function), a policy enforcement device (e.g., Policy and Charging Enforcement Function, Traffic Detection Function), and various methods are described herein for dynamically excluding active service add-ons from bearer throttling for user terminals. The active service add-on indicates that bandwidth of the service traffic associated with a corresponding service is to be limited to a defined value after the user terminal consumes a defined amount of data associated with the corresponding service during a defined time period. The bearer throttling entails limiting the bearer bandwidth to the defined value after the user terminal has consumed the defined amount of data during the defined time period.

Abstract: A mobile wireless device connects to a network of multiple wireless transceiver stations using a protocol in which a connection is established with a particular transceiver station. If the mobile device moves out of range of the original station, the connection is passed to another station, which then impersonates the original station, without dropping the connection. Preferably, the original station provides a virtual Media Access Control (MAC) address to identify itself when the connection is established, and this virtual MAC address is passed to any successor station. Preferably, the station monitors signal strength and automatically passes the connection by polling its neighbors upon determining that signal strength is getting weak.

Abstract: One embodiment of the present invention provides a system for improving transmission efficiency of a wireless link. During operation, the system receives a packet for transmission, where in the packet includes an original sequence number. The system then modifies the packet by including a virtual sequence number in a header of the packet and including the original sequence number in a payload of the modified packet. The system further aggregates a number of modified packets into an aggregate frame and transmits the aggregate frame to a destination device. The virtual sequence number facilitates stateless transmission of the encapsulated packets and allows the aggregate frame to have a maximum allowable number of packets while accommodating both re-transmitted packets and regular packets.
