摘要:
A wireless access point supports data rates and advertises an indication of a minimum data rate for advertisement. Those of the supported data rates that are less than the minimum data rate for advertisement are reserved for limited use. A mobile station that requests to communicate with the wireless access point at one of the one or more supported data rates that are reserved for limited use is informed by the wireless access point how much time communications with the wireless access point at one or more of the one or more supported data rates reserved for limited use will be permitted.
摘要:
A source device has a wireless communication interface. Through the wireless communication interface, the source device establishes a communication session over a wireless medium with a sink device and determines a maximum capacity of a buffer at the sink device for receipt of audio samples to be transmitted in packets from the source device to the sink device in an asynchronous connectionless link over the wireless medium. Scheduling access to the wireless medium by the wireless communication interface for transmission of audio samples on the link takes into account the maximum capacity of the buffer.
摘要:
A method for adjusting a gain level for a receiver of a first radio simultaneously operational with a transmitter of a second radio, comprising: determining a signal-to-noise ratio (“SNR”) value for signals received by the receiver from an access point (“AP”); and, when the first radio is associated with the AP and the transmitter is not transmitting, if the SNR value exceeds a SNR threshold, reducing the gain level for the receiver from an initial level and initiating transmission from the transmitter, otherwise maintaining the gain level for the receiver at the initial level and initiating transmission from the transmitter; wherein the SNR threshold is a SNR value above which beacon signals from the AP can be successfully received by the receiver.

摘要:
To improve network coverage or reduce false handover triggering, at least one client terminal is set to operate as a virtual access point (VAP) in a first wireless network by an AP controller. If a mobile device detects that a signal quality estimate of communications via an AP of the first wireless network is below a first value, the mobile device performs a handover procedure to the VAP. While maintaining the call via the VAP, if the mobile device detects that the signal quality estimate is back above the first value, the mobile device performs a handover procedure back to the AP of the first wireless network. On the other hand, if the mobile device detects that the signal quality estimate is below a second value which is less than the first value, the mobile device performs a vertical handover procedure from the VAP to a base station of a second wireless network.
摘要:
The disclosure describes a system, method, device and server for establishing communication links in a network for a device. Communications may be carried from the device through an intermediary communication device to an access point in a wireless communication network. The method comprises: monitoring for a first trigger condition to seek the intermediary communication device, where the trigger condition is related to at least one of the communication device or the network; and upon detection of the first trigger condition identifying the intermediary communication device in the network, establishing a first connection between the communication device and the intermediary communication device and a second connection between the intermediary communication device and the access point to transmit communications from the communication device to the access point and transmitting a message from the communication device for the access device using the first connection and the second connection.
摘要:
A mobile communication device is operative to perform a first communication function (e.g. inquiry or paging function for discovery) with use of a first radio frequency (RF) transceiver (e.g. BLUETOOTH transceiver) and a second communication function (e.g. voice telephony function) with use of a second RF transceiver (e.g. IEEE 802.11 transceiver). In response to identifying an indication to invoke the first communication function while the second communication function is being performed, the mobile device reserves selected timeslots of a wireless communication link with the first RF transceiver for establishing a synchronous link. The mobile device then causes data of the first communication function to be communicated, via the first RF transceiver, during remaining unreserved timeslots of the wireless communication link. The mobile device further causes data of the second communication function to be communicated, via the second RF transceiver, during the reserved timeslots of the synchronous link.
摘要:
A mobile communication device includes a first radio frequency (RF) transceiver and a second RF transceiver. The first RF transceiver is operative for communications in accordance with a first radio protocol (e.g. BLUETOOTH®) using a first set of RF channels, and the second RF transceiver is operative for communications in accordance with a second radio protocol (e.g. IEEE 802.11) using a second set of RF channels. The mobile device identifies a list of noisy RF channels in the first set of RF channels, detected through operation of the first RF transceiver in accordance with the first radio protocol. The mobile device selects one of the RF channels from the second set based on the identified list of noisy RF channels. The mobile device then controls operation of the second RF transceiver in accordance with the second radio protocol for communicating data to another communication device over the selected RF channel of the second set.
摘要:
An apparatus has a first communication module and a second communication module. The first communication module is compatible with a first wireless communication technology, and the second communication module is compatible with a second wireless communication technology that differs from the first wireless communication technology. Transmissions by the second communication module may contribute to interference at the first communication module. The first communication module refrains from advertising support for any data rate that is not expected to be sufficiently resilient in the face of interference caused by transmissions from the second communication module.
