Abstract: The technical features of this description provides a method and apparatus of processing data associated with handover in a wireless network transmitting a radio signal based on a number of orthogonal frequency division multiplexing (OFDM) symbols or single carrier frequency division multiple access (SC-FDMA) symbols. In an aspect of the features, when MME learns that HeNB is preparing handover of UE, it sends the UE a PDN CONNECTIVITY REJECT with a proper cause, so that LIPA PDN connection cannot be used in the target cell. Accordingly, the LIPA PDN connection is only restricted to a CSG cell. Moreover, the network can explicitly reject the request from the UE, either before or after handover, thereby avoiding the UE's unnecessary retry.

Abstract: A network stack sends very large packets with large segment offload (LSO) by performing multi-pass LSO. A first-stage LSO filter is inserted between the network stack and the physical NIC. The first-stage filter splits very large LSO packets into LSO packets that are small enough for the NIC. The NIC then performs a second pass of LSO by splitting these sub-packets into standard MTU-sized networking packets for transmission on the network.

The SRA is defined for transmitting traffic data between the AP and the STA, and the MSRA is defined for transmitting management and control data between the AP and the STA. The system reduces station battery consumption, supports higher throughput for non-real time (NRT) traffic and is more efficient for real time (RT) traffic while maintaining full compatibility.
