Abstract: Techniques for supporting operation on multiple carriers are described. In an aspect, a carrier indicator (CI) field may be used to support cross-carrier assignment. The CI field may be included in a grant sent on one carrier and may be used to indicate another carrier on which resources are assigned. In one design, a cell may determine a first carrier on which to send a grant to a UE, determine a second carrier on which resources are assigned to the UE, set a CI field of the grant based on the second carrier and a CI mapping for the first carrier, and send the grant to the UE on the first carrier. The UE may receive the grant on the first carrier from the cell and may determine the second carrier on which resources are assigned to the UE based on the CI field of the grant and the CI mapping for the first carrier.

Abstract: A device associated with a Voice over IP (VoIP) network receives a call from a mobile device. The device determines whether a sector identifier (ID) associated with the call includes a femtocell identifier. The device further determines a location identifier included in the sector ID when the sector ID includes the femtocell identifier. The device also identifies a recipient of the call based on the location identifier and forwards the call to the recipient.

Abstract: Disclosed are techniques for hosting a communication session in a call server between communication devices. The call server functions as a bridge service between the communication devices joining an original communication link between the first communication device and the call server with a second communication link between the second communication device and the call server. The first communication device includes at least two RF transceivers each capable of communicating with the call server over a separate network using separate telephone numbers. The call server establishes an alternate communication link with the first communication device on an alternate network and joins it with the second communication link before disabling the original communication link to maintain the communication session between the communication devices.

Abstract: Systems and methods described herein employ techniques for generation and selective activation (or triggering) of network management policies in a congested network to, for example, prevent further aggravation of network congestion are disclosed. In order to address mobile network congestion it is necessary to be able to enforce network management policies on the devices which are in the a specific congested cell. This presents a challenge as the mobile devices cannot themselves determine if the cell they are currently located in is congested. Additionally, most network operators do not have mechanisms to determine which cells are congested in real-time. Thus, network operators (e.g., cellular providers) can create policies with congestion triggers that are not bound to specific cells to address congestion. The polices can be distributed to clients in the mobile network and selectively activated in congested cell locations (or areas) by the mobile clients.

Abstract: Disclosed are techniques for establishing a communication session in a call server between communication devices. A call server receives a communication session establishment message from a communication device that has an associated VoIP telephone number. The message is indicative of the communication device wanting to place a call to a target communication device that has an associated target telephone number. The communication session establishment message includes the VoIP telephone number, the target telephone number and a connection status indicator. The call server establishes a first communication link with the device based on the connection status indicator. The call server then establishes a second communication link with the target communication device. The call server may then join the first and second communication links to establish a communication session between the communication devices.

Abstract: A system and method for achieving lossless packet delivery in packet rate oversubscribed systems. Link-level packet rate control can be effected through the transmission of packet rate control messages to link partners of an oversubscribed system. The transmission of packet rate control messages can be triggered upon a determination that a packet arrival rate over a set of ingress ports exceeds a packet processing rate of a packet processing unit bound to the set of ingress ports. In one embodiment, the packet processing rate is artificially reduced due to a reduction in power consumption in the oversubscribed system.

Abstract: Techniques are provided for reducing power consumption in wireless communication devices. During an idle listening period, the clock rate of the receiver in the device is reduced. Data packets received by the receiver are then sampled at the reduced clock rate. A determination is made as to whether the data packet is intended for the device. The clock rate is restored to the full clock rate when the data packet is intended for the device. On the other hand, the receiver continues to operate at the reduced clock rate when the data packet is not intended for the device.

Abstract: A radio resource control (RRC) message is received by a radio resource control (RRC) device of a user equipment (UE). The RRC message notifies the FDD UE of a high speed dedicated shared channel (HS-DSCH) inter-Node B cell change. A reordering buffers of a medium access controller-high speed (MAC-hs) is flushed in response to the receiving the RRC message. A status report is generated for each acknowledge mode (AM) RLC instance mapped to the HS-DSCH by a radio link control (RLC) device after the MAC-hs flushes the reordering buffer. Each status report indicates missing AM RLC packet data units (PDUs). The RRC device sends a “TRANSPORT CHANNEL RECONFIGURATION COMPLETE” message on a DCCH after the RLC device generates each status report.

Abstract: While directional communication using millimeter waves is realized, the number of communication stations through which simultaneous communication is possible is increased to increase the throughput of the entire system. Beamforming of a transmission beam is performed not only on a data frame, but also on a CTS frame. In a case where the transmission/reception beam of a hidden terminal (STA_C) is in a direction different from that of a data transmission side (STA_A) with respect to a data receiving side (STA_B), the hidden terminal (STA_C) ceases to receive a CTS. Consequently, a transmission stop period is not set, and a communication operation with a communication party terminal (STA_D) thereof can be continued.

Abstract: A mechanism is disclosed for identifying, classifying, and controlling flows in a network. In one implementation, a separate set of behavioral statistics is maintained for each flow. These behavioral statistics are updated as packets belonging to a flow are processed. Whenever a packet belonging to a flow is processed, a set of policies that the flow's behavioral statistics satisfy is determined. For each policy that the flow's behavioral statistics satisfy, actions that are associated with that policy are applied relative to the packet. The actions may be designed to cause a router to handle, in a user-specified manner, packets that are likely to represent a particular kind of traffic. Thus, different flows, such as VOIP, gaming, streaming, and P2P flows, which are associated with different behavioral statistics, may be handled in ways applicable for the specific application traffic type.

Abstract: A relay device relays between two TCP communication items of a LAN side and a WAN side. When a line bandwidth of the WAN side is smaller than a line bandwidth of the LAN side, buffer overflow in a LAN side reception buffer and a WAN side transmission buffer of the relay device is prevented, and a connection is prevented from being forced to be canceled. A value of a reception window size (rwnd) described in an ACK packet returned to a transmission terminal of the LAN side is controlled based on a transmission throughput, a discarding rate, and an RTT measured in TCP communication of the WAN side, and a total size of unarranged data and a size of arranged data in a reception buffer of the LAN side and a size of untransmitted data and ACK awaiting data in a transmission buffer of the WAN side.
