Abstract: A method and apparatus are disclosed for bidirectional applications where the source application entity and/or the destination application entity may align the uplink data transfer instances and the downlink transfer instances so that they are close to each other or overlap with each other. This may enable both uplink data transfer and downlink data transfer to take place in a single active state of the client terminal. This may reduce the rate at which the client terminal has to turn on and turn off its transmitter, receiver and other modules which may in turn reduce the client terminal transitions from sleep state to active state and vice versa. This may reduce the amount of time the client terminal spends in the active state. This may significantly reduce the power consumption in client terminal, which may be a significant advantage for battery operated client terminals.

Abstract: A system and method for implementing fallback on a wireless device for circuit switched fallback from a first network that does not provide a circuit switched domain service is presented. A paging message is received from the first network. The paging message instructs the wireless device to implement circuit switched fallback to a circuit switched network. The paging message is inspected for information indicative of a service associated with the paging message, and a channel type suitable for the service is determined from the information indicative of the service. A request message for initiating the establishment of a radio connection is transmitted. The request message identifies the suitable channel type, and the service is used on the circuit switched network.

Abstract: Aspects described herein relate to receiving communications in contention-based radio access technologies (RAT). Communication resources can be activated for monitoring one or more channels related to a contention-based RAT based at least in part on a discontinuous receive (DRX) cycle. The one or more channels related to the contention-based RAT can be monitored in one or more time periods following activating the communication resources to determine whether communications are received from an access network node. An on-duration timer during which the communication resources remain active to receive the communications in the contention-based RAT can be initialized based at least in part on determining that the communications are received from the access network node. The communication resources can be deactivated following expiration of the on-duration timer.

The communication apparatus further includes a second detection unit configured to detect a service executable by the another communication apparatus based on a communication in a second communication layer that is different from the first communication layer after the communication apparatus has been wirelessly connected to the another communication apparatus, if a detection result obtained by the first detection unit does not indicate that the another communication apparatus is capable of executing a predetermined service.

Abstract: A communication system facilitates a voice communication session for a wireless communication device. A Long Term Evolution (LTE) network exchanges Voice over LTE (VoLTE) communications with the wireless communication device for the voice communication session and determines LTE packet loss metrics for the voice communication session. The LTE network transfers the voice communication session to a Wireless Fidelity (WIFI) network. The WIFI network exchanges Voice over WIFI (VoWIFI) communications with the wireless communication device for the voice communication session and determines WIFI packet loss metrics for the voice communication session. A network controller compares the LTE packet loss metrics with the WIFI packet loss metrics to determine a packet loss configuration for the WIFI network. The network controller transfers a packet loss instruction to the WIFI network.

Abstract: Techniques for configuring/learning the link aggregation groups (LAGs) of a port extender (PE) at the time the PE joins an extended bridge are provided. According to one embodiment, a first network device in a system of network devices (e.g., an extended bridge) can receive a join message from a second network device in the system, where the join message includes a LAG configuration for one or more LAGs programmed on the second network device. The first network device can further determine whether a provisional LAG configuration for the one or more LAGs of the second network device exists on the first network device. If a provisional LAG configuration does not exist on the first network device, the first network device can learn the LAG configuration included in the join message and can integrate the second network device into the system based on the learned LAG configuration.

Abstract: Technologies are described for performing hybrid rate control that switches between a delay-based mode and a passive loss-based mode for a flow of network traffic. The switching can be performed based on the presence of loss-based TCP network flows. For example, rate control can be performed for a flow of network traffic in a delay-based mode. When the presence of a loss-based TCP network flow is detected, the flow of network traffic can be switched from the delay-based mode to a passive loss-based mode and rate control can be performed in the passive loss-based mode. When the loss-based TCP flow is no longer detected, the flow of network traffic can be switched back to the delay-based mode.

Abstract: A network controller including a virtual network setter that sets a virtual communication interface; a dummy packet generator that obtains communication progress information representing a communication progress state of communication of the second processing device with the connection destination device by causing the virtual communication interface to process a dummy packet that causes a receiver of the dummy packet to falsely recognize that the dummy packet is transmitted from the connection destination device; a reset packet generator that generates a reset packet containing the communication progress information; and a reset packet processor that removes, based on the reset packet, connection record information of the second processing device and the connection destination device, the connection record information being stored in the second processing device. This configuration prevents congestion when a processor is switched to another in a cluster system from occurring.
