Abstract
Techniques of barometric calibration of altitude determination by user equipments in a mobile communications network are discussed. In various embodiments, for a plurality of the user equipments, at least one subset of the user equipments is established. Barometric calibration data is determined for the established at least one subset and sent to the user equipments.
Claims24
A method of providing barometric calibration data to a given user equipment in a mobile communications network, the method comprising:
- a network node receiving a respective calibration request from each one of a plurality of user equipments, the plurality of user equipments including the given user equipment,
- establishing at least one subset of the plurality of user equipments which includes the given user equipment based on the calibration requests,
- determining the barometric calibration data for the established at least one subset, and
- sending the barometric calibration data at least to the given user equipment.
A network node of a mobile communications network, the network node being configured to provide barometric calibration data to a given user equipment of the mobile communications network, the network node comprising:
- an interface configured to receive a respective calibration request from each one of a plurality of user equipments, the plurality of user equipments including the given user equipment,
- at least one processor configured to establish at least one subset of the plurality of user equipments which includes the given user equipment based on the calibration requests and further configured to determine the barometric calibration data for the established at least one subset,
- wherein the interface is further configured to send the barometric calibration data at least to the given user equipment.
(canceled)
A method of determining an altitude of an user equipment in a mobile communications network, the method comprising:
- receiving a first part of a barometric calibration data,
- based on the received first part of the barometric calibration data, measuring and/or adjusting a barometric pressure value using a barometric pressure sensor,
- receiving a second part of the barometric calibration data,
- in dependence of the second part of the barometric calibration data and/or in dependence of the measured barometric pressure value, determining an altitude of the user equipment.
A user equipment in a mobile communications network, comprising:
- an interface configured to receive a first part of a barometric calibration data, and
- a barometric pressure sensor configured to measure and/or adjust a barometric pressure value based on the received first part of the barometric calibration data,
- wherein the interface is further configured to receive a second part of the barometric calibration data, and
- at least one processor configured to determine an altitude of the user equipment, in dependence of the second part of the barometric calibration data and/or in dependence of the measured barometric pressure value.
