Abstract

A management of storage of measurement Data is provided. A method of managing storage of a set of measurement data comprises the steps of determining whether a value of at least one of said plurality of parameters has changed by more than a threshold amount from a value of the parameter in a previously stored set of measurement data and storing the set of measurement data, dependent upon the determination being affirmative.

Claims

1. A method of managing storage of a set of measurement data, the method being suitable for use at a user equipment of a wireless network, the set of measurement data comprising a value of each of a plurality of parameters, the method comprising:

receiving a request for measuring the plurality of parameters from the wireless network;

measuring the plurality of parameters in response to the request, if usage of communication resources at the user equipment is below a predetermined value;

determining whether a value of at least one parameter of the plurality of parameters has changed by more than a threshold amount from a value of the at least one parameter in a previously stored set of measurement data;

only if the value has changed by more than the threshold amount and a quality of a serving cell is below a threshold value, storing the set of measurement data,

wherein the at least one parameter comprises a Radio Frequency (RF) fingerprint.

2. The method according to claim 1, wherein the at least one parameter comprises a descriptor of a geographical location, and the threshold amount relates to changes in geographical location.

3. The method according to claim 2, wherein the descriptor of a geographical location is derived from a radio signal received from the wireless network.

4. The method according to claim 1, wherein the at least one parameter comprises a measured attribute of a radio signal, and the threshold amount relates to changes in the measured attribute.

5. The method according to claim 4, wherein the measured attribute of a radio signal comprises a power level.

6. The method according to claim 1, wherein the plurality of parameters includes at least a descriptor of a geographical location and a measured attribute of a radio signal.

7. The method according to claim 1, comprising receiving a message from the wireless network indicating the threshold amount.

8. The method according to claim 1, comprising sending a message to the wireless network indicating that data comprising the set of measurement data is ready to be sent.

9. The method of claim 8, wherein the measurement data is sent using delta signaling sending information relating to a difference from previously sent information.

10. The method according to claim 1, comprising sending the set of measurement data in a response to a request from the wireless network.

11. A User Equipment (UE) configured for use in a wireless network, the UE comprising:

a communication unit configured to receive a request for measuring a plurality of parameters from the wireless network;

a measurer configured to measure the plurality of parameters;

a storage configured to store a set of measurement data; and

at least one controller configured to control to;

manage storage of the set of measurement data, the set of measurement data comprising a value of each of the plurality of parameters;

measure the plurality of parameters in response to the request, if usage of communication resources at the user equipment is below a predetermined value;

determine whether a value of at least one parameter of the plurality of measured parameters has changed by more than a threshold amount from a value of the at least one parameter in a previously stored set of measurement data; and

only if the value has changed by more than the threshold amount and a quality of a serving cell is below a threshold value, store the set of measurement data,

wherein at least one parameter comprises a Radio Frequency (RF) fingerprint.
