Abstract: Technologies for managing congestion of a communication channel includes a network device for receiving a network packet from a computing device destined for another computing device, analyzing network traffic flows over a communication channel established between the network device and an upstream network device, and determining whether the communication channel is congested as a function of the network traffic flows. Such technologies may also include storing the received packet in a local storage in response to determining that the communication channel is congested, transmitting an acknowledgement packet to the computing device in response to storing the received network packet local storage, and transmitting the stored network packet to the upstream network device in response to determining that the communication channel is no longer congested.

Abstract: A method of transmitting control information in a wireless communication system includes configuring a burst including data symbols and a midamble and transmitting the burst through an uplink shared channel. The data symbols and the midamble carry the same control information. Even if control information is transmitted on an uplink shared channel, reception errors in a base station can be reduced by improving transmission reliability.

Abstract: Service continuity is provided when a user equipment (UE), employing local breakout mechanisms at a femto access point (FAP) for a communication session, moves out of the femto coverage area. In particular, a network change detection component can be employed to detect when the UE, attached to the FAP, changes its connection from the femto network to the macro network. Further, an active communication session can exist between the UE and a device/service/application on a local Area network (LAN) connected to a FAP, and/or the Internet, which utilizes local breakout at the FAP. When the UE moves out of the femto network, a context management component can be employed to seamlessly resume the communication session, via the macro network.

Abstract: Local breakout mechanisms can be performed by a femto access point (FAP) to facilitate efficient utilization of backhaul and/or macro networks. In particular, a slave Gateway GPRS Support Node (GGSN) can be integrated within the FAP to directly route the incoming traffic from a user equipment (UE) at the FAP. In one example, Internet bound traffic can be directly routed to the Internet, without employing macro network resources. Further, the system can avoid hairpinning by routing traffic between the UE and a home Local Area Network (LAN) by a anchoring a call or a session in the slave GGSN and facilitate integration of UEs with home applications by employing a UE Digital Home Agent. In addition, the FAP can perform UE-to-UE CS media breakout to facilitate communication between UEs attached to the FAP, without routing the traffic through the core macro network.
