Method and device for managing signal measurements in a wireless network
First Claim
1. A method for managing signal measurements at a station operating in a wireless network comprising at least said station and a Centralised Measurement Manager (CMM) unit, said method comprising:
- receiving, at said station, a measurement request message including measurement parameters and trigger parameters, the measurement request message requesting said station to measure at least one channel characteristic based on the measurement parameters, the measurement parameters specifying at least a channel identifier indicating a transmission channel to be measured, a measurement start time, and a measurement duration, and the trigger parameters including at least a trigger value and a trigger number;
measuring the at least one channel characteristic of the transmission channel to be measured corresponding to the received channel identifier starting at a time period specified by the measurement start time and continuing during a time period specified by the measurement duration, to obtain measurement results for the at least one channel characteristic;
determining a number of the measurement results that satisfy a condition of the trigger value to produce a number of satisfied conditions;
comparing the number of satisfied conditions to the trigger number to obtain a trigger result indicating whether the number of satisfied conditions is equal to or greater than the trigger number; and
transmitting an indication of or at least part of the measurement results to said CMM unit based on the trigger result.

Abstract
A wireless network comprises at least one station (102) adapted to perform measurements of at least one given type in the network, and a Centralised Measurement Manager (CMM) unit (101) for handling measurements of said type. CMM unit sends a measurement request message (201) requesting that this station (102) perform a measurement of the given type, this request message comprising a triggering information (304, 501, 601-602). Upon reception of the measurement request message (201), the station performs (202) a measurement and obtains (203) corresponding measurement result. Then, it is decided (204) whether at least part of the measurement results is to be sent to the CMM unit based on the triggering information. If yes, the station sends the corresponding part of the measurement result to the CMM unit.

8. A communication station configured to cooperate with a Centralised Measurement Manager (CMM) unit in order to manage measurements in a wireless network, said station comprising:
-
an interface unit configured to receive a measurement request message including measurement parameters and trigger parameters, the measurement request message requesting said station to measure at least one channel characteristic based on the measurement parameters, the measurement parameters specifying at least a channel identifier indicating a transmission channel to be measured, a measurement start time, and a measurement duration, and the trigger parameters including at least a trigger value and a trigger number; a measurement unit configured to measure the at least one channel characteristic of the transmission channel to be measured corresponding to the received channel identifier starting at a time period specified by the measurement start time and continuing during a time period specified by the measurement duration, to obtain measurement results for the at least one channel characteristic; and a decision unit configured to determine a number of the measurement results that satisfy a condition of the trigger value to produce a number of satisfied conditions, to compare the number of satisfied conditions to the trigger number to obtain a trigger result indicating whether the number of satisfied conditions is equal to or greater than the trigger number, and to transmit an indication of or at least part of the measurement results to said CMM unit based on the trigger result. - View Dependent Claims (9, 10, 11)

12. A Centralised Measurement Manager (CMM) unit configured to handle measurements in a wireless network comprising at least one station configured to perform the measurements, said CMM unit comprising:
-
an interface unit configured to transmit a measurement request message to said at least one station and to receive an indication of or the at least part of measurement results from said at least one station, the measurement request message including measurement parameters and trigger parameters and requesting said at least one station to measure at least one channel characteristic based on the measurement parameters and to obtain the measurement results, the measurement parameters specifying at least a channel identifier indicating a transmission channel to be measured, a measurement start time, and a measurement duration, and the trigger parameters including at least a trigger value and a trigger number, the trigger value specifying a condition to be satisfied by the measurement results and the trigger number specifying a number of measurement results that satisfy the condition before the indication of or at least part of the measurement results are transmitted, the measurement results being measured by said at least one station on the transmission channel to be measured corresponding to the received channel identifier starting at a time period specified by the measurement start time and continuing during a time period specified by the measurement duration.
