Abstract:
Various methods are provided for facilitating the transmission of a proximity health alert from a device to other local devices upon a determination that a person is in need of help and that local, immediate help is sought. One example method may comprise performing a condition detection process resulting in a determination of whether help is needed, causing activation of a local wireless network interface in an instance in which the performance of the condition detection process results in a determination that help is needed, continuing to perform the condition detection process in an instance in which performance of the condition detection process results in a determination that help is not needed, performing a help request transmission process resulting in identification of a helper device, and causing transmission of additional information to the helper device.
Abstract:
A method comprises composing, by a wireless device in a wireless network, a service ID indicating support for providing proxy service discovery for other wireless devices operating in the wireless network; and transmitting, by the wireless device, a wireless service discovery frame to the wireless network, the service discovery frame including the composed service ID.
Abstract:
A method to manage of coexistence between infrastructure networks and peer-to-peer groups, including receiving, by a peer-to-peer wireless client device associated with a peer-to-peer wireless group owner device in a peer-to-peer wireless network, channel usage information of a wireless infrastructure network, from a wireless access point device managing the wireless infrastructure network; and transmitting, by the peer-to-peer wireless client device, the received channel usage information of the wireless infrastructure network, to the peer-to-peer wireless group owner device, as coexistence information.
Abstract:
A method, apparatus and computer program product are provided for facilitating efficient patient identification in conjunction with an emergency call. In regards to a method, an emergency call from an intermediary device is received, and a search for one or more potential patient devices in proximity to an intermediary device is initialized. The method also includes receiving a unique identifier associated with a patient device from among the one or more potential patient devices. Further, the method retrieves medical information or medical record for a patient associated with the unique identifier. A corresponding apparatus and computer program product are also provided. Either Bluetooth Low Energy or WI-FI Aware are used. The mobility status comprising acceleration information of each patient device is transmitted.
Abstract:
This document discloses a solution for providing channel usage information. In an embodiment, an apparatus managing a wireless network and being in an unassociated state towards an access node managing another wireless network is provided with the channel usage information. The channel usage information is provided together with a further information element enabling the apparatus to verify that the channel usage information originates from a trusted source.
Abstract:
An apparatus and a method for controlling discoverability are disclosed. The solution includes obtaining information of at least one scan on at least one communication channel and selecting a discovery mode for an access point from at least two different modes on the basis of the information.
Abstract:
A method and apparatus for detecting, by a first device, a timing measurement frame from a second device, the timing measurement frame having a plurality of time measurement samples, wherein at least the first of the measurement samples has a transmit timestamp value; determining transmit timing values for the subsequent measurement samples; applying a receive timestamp value to each of the received measurement samples; and determining a relative clock drift between a clock of the first device and a clock of the second device by comparing the receive timestamp values with transmit timing values of one or more measurement samples contained in the frame.
Abstract:
This document discloses a solution for selecting a network discovery method in an apparatus. According to an aspect, the apparatus performs the following: performing initial channel assessment of a radio channel at maximum a determined time period shorter than or equal to the shortest of a plurality of discovery frame broadcast periodicities employed by access nodes the apparatus is configured to search for in network discovery; upon determining that a transmission has been detected in the initial channel assessment, selecting a network discovery according to a first network discovery method; and upon detecting no transmission on the radio channel during the initial channel assessment, selecting network discovery according to a second network discovery method different from the first network discovery method
Abstract:
An example method comprises receiving by an apparatus, a message from an access node, including at least one of a delay value indicating a duration to wait before beginning to contend for access to the wireless network by a random backoff procedure to get a transmission opportunity, and an indication whether or not the apparatus is to use a predefined delay value to wait before beginning to contend for access; determining whether to use the delay value to wait before beginning to contend for access to the wireless network; waiting for a duration represented by the delay value, when the apparatus has data to transmit over the wireless network; and beginning to contend for access to the wireless network by a random backoff procedure after the wait duration, before initiating transmission.
Abstract:
This document discloses a solution for determining distances. In the solution, a first frame is transmitted (200) to a second apparatus; a second frame is received (202) from the second apparatus, as response to the first frame; an indication of the duration between the reception time of the first frame and transmission of the second frame is received (204); an indication whether the duration is constant or variable is received (206); and in case the duration is constant, the distance between the first apparatus and the second apparatus is determined (208) based at least partly on the indication of the duration.
