摘要:
A system for selectively expediting connection establishment between apparatuses. In accordance with at least one embodiment of the present invention, an apparatus may sense a first change in the disposition of the apparatus, and may initiate device discovery based on the first sensed change. A determination may then be made in the apparatus as to whether another apparatus encountered by the apparatus during device discovery satisfies a predetermined response criteria. The apparatus may then select the other apparatus if it is determined that the other apparatus satisfies the predetermined response criteria.
摘要:
A wireless device transmits beacon packets at periodically occurring time intervals across a wireless channel. When the wireless communications device has not formed a piconet with one or more remote devices, the device scans the wireless channel for a predetermined amount of time immediately following each of the periodically occurring time intervals. During this time a remote device may respond to the beacon packet.
摘要:
A system for facilitating short-range wireless data exchanges between apparatuses that are not linked by a wireless network connection. For example, an apparatus may initially determine if data suitable for transmission without first establishing a formal network connection is pending. For example, in terms of Bluetooth the data may suitable for transmission to another apparatus without having to first negotiate a Bluetooth piconet including both apparatuses. If it determined that data is pending for transmission, the apparatus may scan for apparatus detection packets transmitted from other apparatuses (e.g., enter an inquiry scanning mode). Upon reception of an apparatus detection packet, the apparatus may transmit one or more messages via wireless communication (e.g., execute an extended inquiry response procedure) comprising at least the data.

An apparatus comprises at least one processor, and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to receive a signal indicative of a request to initiate a wireless communication session using an antenna of a first wireless communication device, and responsive to the signal, to cause an indicator to be displayed on a display of the first wireless communication device, the indicator being configured to indicate to a user an orientation of the first wireless communication device with respect to a second communication device for facilitating the initiation of a wireless communication session between the first wireless communication device and the second wireless communication device using the antenna.
摘要:
Example method, apparatus, and computer program product embodiments are disclosed to enable out-of-band short-range communication carrier transport switching for connection setup of in-band device-to-device communication. Example embodiments of the invention include a method comprising the steps of transmitting, by a first device via an out-of-band short-range communication carrier, an indication to a second device that a carrier switch from the out-of-band short-range communication carrier to an in-band short-range communication carrier is desired; receiving in response to the transmitted indication, a response from the second device via the out-of-band short-range communication carrier including an indication that the carrier switch from the out-of-band short-range communication carrier to the in-band short-range communication carrier is confirmed; and modifying, by the first device, device detection procedure associated with the in-band short-range communication carrier to improve detection of paging signals on the in-band short-range communication carrier.
摘要:
A method for use by a device communicating according to a short-range wireless connectivity protocol in attempting to establish a connection to another device using an enhanced inquiry and/or paging procedure as part of the connection procedure, the method including a step in which the device transmits a first packet for establishing a connection to the other device, and the other device responds with one or more response packets whose content depends on whether the other device is configured to perform the enhanced procedure. In some embodiments, the first packet is an identifier packet including extension data indicating via a predetermined bit pattern that the device is itself configured to perform the enhanced procedure.
摘要:
A method and system of controlling a multicast transmission. The method and system transmits a data packet to multiple slave devices across a UWB wireless network, and detects the reception of any acknowledgement transmissions. These acknowledgement transmissions indicate reception of the data packet by the slave devices. In addition, the method and system retransmit the data packet to at least one of the slave devices when an acknowledgment is not detected for each of the slave devices. The acknowledgments may be received from the UWB network.
摘要:
A system for managing the simultaneous operation of a plurality of radio modems in a single wireless communication device (WCD). The multiradio control may be integrated into the WCD as a subsystem responsible for scheduling wireless communications by temporarily enabling or disabling the plurality of radio modems within the device. The multiradio control system may comprise a multiradio controller (MRC) and a plurality dedicated radio interfaces. The radio interfaces are dedicated to quickly conveying delay sensitive information to and from the radio modems. The modems may further include control features that take information from the MRC as an input in determining the priority of messages to be sent out to a receiving device.
摘要:
A communication method includes establishing a wideband communication link between a first device and a second device, transmitting a first set of consecutive data bits from the first device to the second device by means of a first set of pulses, and transmitting a second set of bits from the second device to the first device at least partially simultaneously or at least partially interlaced with the first set of bits.
摘要:
A method, system and program code are provided to implement a wireless network having a plurality of devices in which one of the devices coordinates wireless communications between the devices. The method and system evaluates device parameters of one or more of the plurality of devices, the device parameters including at least available power source characteristics for a device; and determines a coordinator from the plurality of devices based on at least the available power source characteristics, such as an available power source capacity, for the one or more of the plurality of devices, the coordinator adapted to coordinate wireless communications between the devices in the wireless network.
