Abstract
A central node receives, from each of a plurality of access points providing access for user equipments to a communication network, a result of a measurement related to a position of a user equipment, receives additional information comprising at least one of an evaluation of the result of the measurement and a reference towards which the measurement was done, and calculates the position of the user equipment by combining the results of the measurements received from the plurality of access points using at least one of the evaluation and the reference.
Claims20
A method executed by an access point of a plurality of access points which provide access for user equipment to a communication network, the method comprising:
- acquiring a result of a measurement related to a position of a user equipment, wherein the result comprises an angle of arrival of signals transmitted between the user equipment and the access point;
- acquiring additional information comprising:
- an evaluation of the result of the measurement, wherein the evaluation comprises a quality of the measurement comprising at least one item of the following group:
- a reliability of the measurement,
- a likelihood of the measurement,
- a quality index of the measurement, and
- a signal to noise ratio on a channel via which the signals transmitted between the user equipment and the access point are received;
- and
- a reference towards which the measurement was done, wherein the reference comprises at least one of a reference direction to which the angle of arrival was measured and an orientation of an antenna array;
- and
- transmitting, to a central node, in at least one message, the result of the measurement and the additional information, wherein the additional information is to be used by the central node for combining the result of the measurement related to the position of the user equipment, which have been acquired by the plurality of access points.
A method executed by a user equipment, the method comprising:
- acquiring additional information comprising
- an evaluation of a result of a measurement related to a position of the user equipment and a reference towards which the measurement was done, wherein the result comprises an angle of arrival of signals transmitted between the user equipment and an access point, wherein the reference comprises at least one of a reference direction to which the angle of arrival was measured and an orientation of an antenna array, and wherein the evaluation comprises a quality of the measurement comprising at least one item of the following group:
- a reliability of the measurement,
- a likelihood of the measurement,
- a quality of index of the measurement, and
- a signal to noise ratio on a channel via which the signals transmitted between the user equipment and the access point are received,
- wherein the additional information is to be used by a central node for combining the result of the measurement related to the position of the user equipment, which are acquired by a plurality of access points which provide access for user equipments to a communication network;
- and
- transmitting the additional information to at least one of the plurality of access points.
An apparatus of a plurality of apparatuses which provide access for user equipment to a communication network, the apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions, wherein the instructions, when executed by the at least one processor, cause the apparatus at least to perform:
- acquiring a result of a measurement related to a position of a user equipment, wherein the result comprises an angle of arrival of signals transmitted between the user equipment and the access point;
- acquiring additional information comprising:
- an evaluation of the result of the measurement, wherein the evaluation comprises a quality of the measurement comprising at least one item of the following group:
- a reliability of the measurement, a likelihood of the measurement,
- a likelihood of the measurement, a quality index of the measurement, and a signal to noise ratio on a channel via which the signals transmitted between the user equipment and the access point are received;
- and
- a reference towards which the measurement was done, wherein the reference comprises at least one of a reference direction to which the angle of arrival was measured and an orientation of an antenna array;
- and
- transmitting, to a central node, in at least one message, the result of the measurement and the additional information, wherein the additional information is to be used by the central node for combining the result of the measurement related to the position of the user equipment, which have been acquired by the plurality of apparatuses.
