    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: An access point generates beacons at different power levels at different times to provide an acceptable tradeoff between coverage area associated with the beacons and outage experienced at nearby access terminals. For example, a femto access point may transmit beacons at a relatively low power for a relatively long period of time to reduce interference at nearby access terminals that are being served by a macro access point. The femto access point may then transmit beacons at a relatively high power for a relatively short period of time to enable nearby access terminals to receive the beacons. Also, a given transmit chain may be used to provide frequency hopping of high and low power beacons.

    摘要: Broadcast or multicast traffic is classified into different types of traffic such that different types of traffic are transmitted over different sub-networks. In addition, different transmission schedules may be associated with each of the different sub-networks. A device may thus be configured to receive only a selected portion of the different types of traffic by only waking from a power save mode at the intervals at which the corresponding sub-network sends the traffic. The standby time of the wireless station may thus be improved because the wireless station may awaken less frequently and for shorter periods of time. Different sub-networks carrying different types of broadcast and multicast traffic may be implemented in an 802.11-based system. For example, a single access point may define multiple basic service set identifiers for a single wireless channel.

    摘要: An access terminal scans for nearby access points and maintains a candidate list of access point with which the access terminal may associate in the event the access terminal's communication with its current access point deteriorates for some reason. This search procedure may be performed in a proactive manner whereby the access terminal repeatedly performs scans and updates its list of candidate access points when it is powered on. In some aspects, the search procedure used by the access terminal may be based on a state of the wireless device. In addition, different states of the access terminal may be associated with different optimization criteria.

    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 conservers 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.
