Abstract: User equipment in a wireless communication system monitors scheduling information and locally detects a change in link data rate of the uplink channel based on the monitored scheduling information. In this way, a change in link data rate can be detected directly without significant delay. This direct or early detection of a rate change is then combined with an appropriate system reaction. The information of the detected change in link data rate is preferably utilized for adapting the application data rate of an IP application running in the user equipment. As an alternative, or as a complement, data packets are classified based on relative importance and selected for transfer of information over the uplink channel based on the classification of data packets and in dependence on the detected change in link data rate.

Abstract: Embodiments of the present invention provide a system and method for using network flows records exported from network routers to provide information about the traffic entering/exiting the device. Network routers or hubs can be configured to authorize or deny various types of network traffic between two network devices whose traffic transits via the router. The method presented describes the creation and application of access control lists on the router from information derived from the network flow information exported by the network router.

Abstract: Systems and methods for providing mobile stations (“MS”) registration to a generic access network (“GAN”) via a wireless LAN interface are disclosed. The MS may receive a rejection message from a GAN controller with a “network congestion” indication set. The MS may also receive a “connection status” information element as part of the rejection message. The MS can determine from the information element whether the MS can release the connections made to a security gateway (“SEGW”) and to the GAN controller and whether it can release its WLAN connection facility. When the MS releases these connections, battery power is conserved while performing a timer decrement loop. At the end of the timer decrement loop, the MS makes another registration request. The network can reallocate resources when the MS releases the connections to the SEGW and the GAN controller. Methods for performing the GAN registration during network congestions are described.

Abstract: Each of the host transmitting/receiving blocks of a plurality of I/O units connected to a CNC reads the destination specification data and a diagnostic result bit each time the host transmitting/receiving block receives a signal packet from the CNC. When the diagnostic result bit indicates the execution of a diagnosis, the signal packet contains diagnostic DO data, and the relevant DO signal output terminal is short-circuited to the relevant DI signal input terminal to form a diagnostic loop. The diagnostic packet signal passes through the diagnostic loop, the external signal transmitting/receiving block, and the host transmitting/receiving block and returns to the CNC through the host transmitting/receiving block of an adjacent I/O unit closer to the CNC. The CNC analyzes the packet signal to determine whether each of the I/O units is operating normally or not.

Abstract: Methods and systems for a fast drop recovery for a TCP connection are disclosed. Aspects of one method may include a receiving device on a network receiving an out-of-order data. The receiving device may then signal to a transmitting device on the network, which sent the out-of-order packet, to enter a congestion alleviation mode without waiting for a delay period. The network packet transfer may be via TCP protocol, for example. The delay period may comprise a retransmission time-out period if the receiving device does not save isles. If the receiving device does save one or more isles, the delay period may be a period associated with delayed ACK. The signal may comprise a TCP option and/or an available TCP flag. The signal may also comprise, for example, three duplicate ACKs. Other similar signals may be used for networks that use other protocols than TCP.

Mesh network data are then routed through the alternative backhaul portal at the mesh access point until it is determined that additional backhaul capacity is no longer required. The mesh access point is then deactivated as an alternative backhaul portal in the mesh network.
