The network retrieves a cached status flag indicating whether the end device is defined on the Zigbee network and transmits the status flag to the end device. If the end device is undefined on the Zigbee network, the end device attempts to re-join the network. During the power saving mode, the network can cache messages intended for the end device and transmit the messages to the end device when the device exits the power saving mode.

Abstract: Keep-alive processing for NAT devices and reducing power consumption in wireless clients. A server driven keep-alive mechanism facilitates keep-alive messages to a NAT device currently providing a connection to a mobile client to refresh the NAT state, thereby reducing or eliminating power consumption in a wireless device to respond to the connection with keep-alive packets. In one instance, keep-alive packets are sent to the NAT device to reset the NAT timeout timer, and then to the mobile client. The client responds only when expected keep-alive packets are not received at the client. In another instance, keep-alive packets reset the NAT timer to maintain the connection but are dropped or self-destruct before reaching the mobile client thereby providing the optimum power conservation in the mobile device. Thus, the client is not forced into extra client activity to send or receive wireless data, thereby draining the battery.

The conventional (or device-level) VPN connection is not used by the app(s). The app has its own IP stack, an HTTP proxy layer, an IPsec module, and a virtual data link layer which it uses to build IP packets, encapsulate them, and transmit them to a transport module in the device operating system, for example, a UDP module.

Abstract: This disclosure relates to a system and method for providing a mechanism control page requests sent in a wireless communication network. The paging control mechanism can be implemented in a gateway through a combination of hardware and software to determine whether packets received at a gateway trigger a page. The packets received at the gateway are intended for user equipment that is indicated to be in an idle state with no bearer connection. The paging mechanism controls paging when paging requests need to be sent. In some communication networks, page requests can be sent that are not needed because a bearer connection or link is in the process of being established. The control can be asserted by adding intelligence to the gateway to determine—on receipt of downlink data or signaling—how to proceed based on the state of the user equipment and the bearer connection.

Abstract: Even when a general user's mobile station in communication enters a use-prohibited cell, the use of the use-prohibited cell is prevented while the communication is being maintained.

Abstract: The invention utilizes a separate queue per output port as implemented in the traditional simple queuing schemes of the prior art. Further, it also uses the information found in the packet header to determine the output port and the next output port. Based on this information, it utilizes queues dedicated to congested flows, or “Congested Flow” queues. When the switch determines that, based on the first output port and the second subsequent output port, a packet in the output queue is destined for a congested path, it sets the offending packet aside in a Congested Flow queue, thereby allowing other packets destined for the first output port to continue to be transmitted. In this way, the HOL blocking issue is addressed, without the need for a significantly increased number of output queues.

The second set of switches form a route associated with the first variable communication paths that is not predefined and that is dynamically defined at a time of automatic rerouting. The logical circuit is added to a deletion batch, and disconnected at the end of the time period.

Abstract: In a packet communication system with large bandwidth delay product (BDP) and employing Transmission Control Protocol (TCP), the reported advertised window size as advertised by a receiver is employed only as an indication of window size and not as a throughput limit so that more data is sent than the amount specified by the advertised window size. Since the receiver can process all incoming TCP packets, the receiving buffer is consistently near empty. Since the TCP's advertised window size is not accepted as the absolute amount of buffer space available at the receiver, the sender is not constrained by the absolute value of the receiver's advertised window size and instead can transmit more data than the absolute value of the advertised window, enabling the system to increase the actual window size without modifying the link ends. This improved large-BDP-capable protocol is denoted TCP-SC.

The audio management system is connected to a user communication device. The system computer is arranged to switch between a data communication service and a voice communication service upon receiving a signal from the radio communication device indicating that a carrier on a predetermined fixed frequency has been detected or has ceased to be detected by the radio communication device, or from the audio management system indicating that a request for a predetermined fixed frequency voice communication service has been detected or has ceased to be detected by the audio management system.

Abstract: In order to carry out actions such as setting up a call from an entity in the address realm of one middlebox to an entity in the address realm of another middlebox, then a middlebox control node such as a call server is used. Previously, the middlebox control node has needed to have pre-configured information about all the middleboxes and which address realms they are associated with. The present invention provides one or more middlebox-identity-providing nodes which are separate from the middlebox control node, and which are more directly connected to the end users of the service than the middlebox control node. This provides greater flexibility in network design and removes the need for middlebox information to be pre-configured at the middlebox control node. Instead, this information is sent to the middlebox control node, as part of signalling messages, from middlebox-identity-providing nodes.
