A user equipment for providing information most relevant to a user as the user becomes impaired or experiences diminishing capacity is disclosed. The user equipment includes a transceiver, a memory, at least one sensor for detecting a biometric measurement of a user of the equipment, a user interface and a processor. The processor filters the biometric measurement, calculates a metric based on the measurement, evaluates the metric, selectively adjusts an amount of information displayed on the user interface based on the evaluated metric and executes an application corresponding to a user actuation of an item of the displayed information.

A display unit in a motor vehicle presents information to a first user located in a personnel site. A frame carries the personnel site and a suspension system between the frame and the personnel site has at least one adjustable suspension characteristic. While the motor vehicle is being operated, a control system repeatedly determines a first gaze point of the first user on the display unit. Variations in a position for the first gaze point over time are analyzed; and in response thereto, the control system generates a first control signal to the suspension system so as to reduce a fluctuation of the position for the first gaze point, if a repositioning of the first gaze point is out of synchronization with a displacement of the display unit.

Motor vehicle and method of controlling a suspension system

A method for enabling Mission Critical Push to Talk (MCPTT) services in a telecommunications network is presented. The method is performed by a mobile terminal (MT) and incudes receiving an imminent peril or emergency MCPTT call from at least one other MT, the call indicating an emergency state for the at least one other MT, determining a number of MTs indicating an emergency state, and raising an MCPTT emergency alert if the determined number of MTs indicating an emergency state exceeds a threshold. An MT, an escalation server, a computer program, and a computer program product are also presented.

Mission critical push to talk services

Method performed by a first communication device operating in a wireless communications network. The wireless communications network comprises a group of communication devices. The first communication device determines that a number of communication devices, comprised in the group of communication devices, having reported that data about a position of a second communication device comprised in the group of communication devices has not been received within a time period, is above a threshold. The first communication device then initiates transmitting an indication to at least one receiving device, indicating a result of the determination. Also disclosed is a method by a third communication device comprised in the group. The third communication device starts a timer defining the time period and, in the absence of the data received within the period, sends a notification of expiration of the timer.

A movement adjusting device adjusts the movement of a transceiver moving according to a plan along a route through a communication network while communicating for an application having a service requirement on the communication network, the communication network comprises cells and the movement adjusting device is operative to: obtain radio network condition data regarding a group of cells comprising a current cell in which the transceiver is located and a number of neighbouring cells into which the transceiver may move, analyse the radio network condition data with regard to fulfilling the service requirement of the application, and make an adjustment of the planned movement if the analysis indicates that this would improve on the fulfilling of the service requirement.

Adjustment of planned movement based on radio network conditions

There is provided a method and corresponding devices for enabling power adjustment of a radio head of an indoor radio system. Basically, the method comprises identifying (S), based on signal strength measurements in relation to wireless communication 5 devices connected to the radio head, presence of a wall of a building in which the indoor radio system is located, and triggering (S) an adjustment of transmit power of the radio head to align the radio head coverage with the wall.

A method performed by a first network node is provided. The first network node, a second network node and a User Equipment, UE, operate in a wireless communications system. The first network node is located indoors, and the second network node is located outdoors. The method comprises any one out of:

Handover of a user equipment between an indoor and an outdoor network node

A method performed by a network node for deciding a probability that a first User Equipment, UE, is located in a building is provided. The network node, the first UE and one or more second UEs operate in a wireless communications network. The network node learns that one or more second UEs are associated to a respective subscription comprised in a group of subscriptions related to the building. The one or more second UEs are decided to be located in said building. The network node identifies cell relation metrics, which relate to the building, for the one or more second UEs associated to the group of subscriptions. The network node then decides the probability that the first UE is located in the building, based on to what extent a cell relation metric of the first UE matches the identified cell relation metrics for the one or more second UEs.

A movement adjusting device adjusts the movement of a wireless transceiver moving according to a plan along a route through a wireless communication network () while communicating for an application having a service requirement on the wireless communication network (), the wireless communication network () comprises cells () and the movement adjusting device is operative to: obtain radio network condition data (RSRP, RSRQ) regarding a group of cells () comprising a current cell () in which the wireless transceiver () is located and a number of neighboring cells () into which the wireless transceiver () may move, analyze the radio network condition data (RSRQ, RSRP) with regard to fulfilling the service requirement of the application (), and make an adjustment of the planned movement if the analysis indicates that this would improve on the fulfilling of the service requirement.

A device for improving readability of content displayed to a viewer is provided. The device has a screen for displaying the content, a motion sensor for measuring a displacement, and an eye tracker for measuring a change in gaze of the viewer when gazing at the screen. The device is operative to adjust the displayed content so as to improve its readability in response to determining that the change in gaze and the displacement of the device are out-of-sync. The out-of-sync condition may be determined by deriving a phase difference between the measured change in gaze and the measure displacement of the device, and comparing the derived phase difference to a threshold value. The displayed content is adjusted by at least one of increasing a font size of displayed text, enlarging one or more displayed graphical objects, and increasing a zoom level of the displayed content.

The invention relates to handover of a mobile station from a source cell to a target cell in a wireless communication network. According to the invention communication improving data in relation to communication between the source cell and the mobile station is collected by a communication improving node prior to handover and communication improving physical layer data being at least based on said collected communication improving data is transferred to a device handling communication between the target cell and the mobile station. The communication handling device then uses the communication improving physical layer data to improve the quality of the initial communication between the mobile station and the target cell after handover to the target cell.

Communication improvement after handover

The invention relates to handover of a mobile station () from a source cell (C) to a target cell (C) in a wireless communication network (). According to the invention communication improving data in relation to communication between the source cell and the mobile station () is collected by a communication improving node () prior to handover and communication improving physical layer data being at least based on said collected communication improving data is transferred to a device () handling communication between the target cell and the mobile station.
