摘要： A method and apparatus is described which provides reliable multicasting in a WLAN. The use of at least two distinct MAC multicast addresses are used to separate the first multicast frame transmissions from subsequent multicast frame re-transmissions. Thereby enabling legacy devices to ignore duplicate retransmitted multicast frames, because the duplicate frames are sent using a multicast address they do not listen to. Thus, the legacy devices are not confused with duplicated frames. In addition, new devices benefit from the retransmissions sent on the second multicast address and can re-order the frames before delivering to the applications or upper layers; thereby improving the QoS for the multicast.

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 and a packet-switched network. While communicating over the packet-switched network, the device negotiates a sleep interval that is longer than the ordinary interval available using the packet-switched network. In this manner, the device wakes less frequently and thereby conserves power. A buffering system is included so that data directed towards the device while it is asleep may be buffered for later delivery when the device awakens.

According to various aspects, systems and methods are described that facilitate providing and/or utilizing reverse direction grants in connection with scheduled channel access. Such systems and/or method can mitigate an amount of unused channel access time after a station completes data transmission prior to an end of the allocated 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： 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： 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： A wireless terminal concurrently associates with multiple wireless local area networks. The wireless terminal may operate in power save mode on both of the WLANs to prevent a disruption of communication on either WLAN. The wireless terminal may adjust the times at which it listens for beacons to enable reception of beacon information even though the beacons for different WLANs may overlap in time. Beacon transmission times also may be scheduled to avoid overlapping transmissions of beacons on different WLANs.

The processor may be configured to maintain in the memory a database containing a list of access points that have previously served the access terminal with at least a minimum quality of service, the processor being further configured to use the list to search for an access point to associate with, or search for an access point to handoff the access terminal to during operation. In addition to, or alternatively, the processor may also be configured to maintain in the database a second list of access points. The database may be used by the processor to search for an access point that is not on the second list to associate with, or handoff the access terminal to.
