摘要： The method and apparatus as described are directed toward techniques and mechanisms to improve efficiency in wireless communication networks through optimization of handover scenarios. Determining whether an intra-base station or inter-node-B handover is too performed, and determining the protocol layers to reset during the handover based at least in part on the type of handover to be performed increases the overall efficiency of the wireless network.

摘要： A data packet communication system employs radio link control (RLC) transmission between a transmitter and a receiver with an Automatic Repeat Request (ARQ) arrangement whereby polling of the receiver is accomplished with reduced amount of redundantly transmitted data, such as between an access node and terminal. Upon a polling event, such as emptying of a transmission buffer of the transmitter, expiration of a polling timer, or reaching a radio link control (RLC) protocol data units (PDUs) count threshold, the transmitter sends a polling command to the receiver. This polling command is smaller than any of the RLC PDUs, which are conventionally resent with a polling bit set to evoke a STATUS PDU from the receiver. With evolving communication standards tending toward larger PDUs, such as in excess of a kilobyte for HSPA+ (High-Speed Packet Access Evolution) and 3GPP LTE (Long Term Evolution), this inefficiency can be of increasing impact.

摘要： The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network, or any cellular network, and a packet-switched network. During hand-over from the first network to the second network, the sender of packets/frames expands or compresses the packet-switched packets using well-known time-warping techniques. At the receiver end, the received time-warped packets and frames from the second network are appropriately selected so that no unwanted artifacts are introduced during playback.

摘要： Methods and apparatus for determining the quality of a communication link transmitting a specified packet type are disclosed. The methodology includes configuring first packets, which share transmission characteristics with a specific packet type, such as a Voice over IP packet, such that the first packets experience similar communication link treatment as the specific packet type. The first packets are then transmitted over the communication link to a quality monitoring server located near a termination equipment of the particular communication link. Second packets, which are transmitted by the server in response to the first packets, are received and evaluated to determine the quality of the communication link based on characteristics of the second packets. Corresponding apparatus are also disclosed.

摘要： Techniques for scheduling flows and links for transmission are described. Each link is an oriented source-destination pair and carries one or more flows. Each flow may be associated with throughput, delay, feedback (e.g., acknowledgments (ACKs)) and/or other requirements. A serving interval is determined for each flow based on the requirements for the flow. A serving interval is determined for each link based on the serving intervals for all of the flows sent on the link. Each link is scheduled for transmission at least once in each serving interval, if system resources are available, to ensure that the requirements for all flows sent on the link are met. The links are also scheduled in a manner to facilitate closed loop rate control. The links are further scheduled such that ACKs for one or more layers in a protocol stack are sent at sufficiently fast rates.

摘要： Techniques to enable efficient operation of co-located WLAN and Bluetooth devices are described. A station (e.g., a cellular phone or a laptop computer) determines the activity of a Bluetooth device and ascertains idle periods of the Bluetooth device. The station communicates with an access point in a WLAN during the idle periods of the Bluetooth device. The station may operate in a power save mode with the access point, send a poll frame to the access point during an idle period, and retrieve the buffered data from the access point during the idle period. The station may also operate in an unscheduled APSD mode with the access point, send a trigger frame to the access point during an idle period to start a service period, and exchange data with the access point during the service period.

摘要： Techniques to efficiently schedule and serve stations in a wireless network are described. An access point may aggregate stations with flows carrying traffic having similar characteristics, e.g., VoIP flows. The access point may schedule these stations together in an overall service period. The access point may serve each station in a respective service period within the overall service period. The access point may send a multi poll frame at the start of the overall service period to indicate the start time and/or service period for each station. Each station may decide to power down until its start time. The service periods for the stations may overlap one another. The service period for each station may cover an initial transmission as well as additional transmission and/or retransmission. If additional transmission and/or retransmission are not needed for a given station, then the next station may be served right away.

摘要： A group of data frames from a plurality of communication channels is received. At least one idle frame including a sequence number of a last frame in the group of data frames is then received. A delay period of time is allowed to elapse after receiving the idle frame before sending a negative acknowledgement message, if at least one data frame is missing.
