Abstract

A method including causing a plurality of measurements to be performed by a user equipment to provide measurement information; causing a message to be sent from the user equipment to a network element indicating that measurement information is available; and responsive to a message from said network element requesting said measurement information, causing a response to be sent from the user equipment to said network with only some of said measurement information and information indicating that further measurement information is available.

First claim

The invention claimed is:

1. A method for a user equipment in a telecommunications network, the method comprising:
entering an idle mode, wherein the user equipment is not in active communication with the telecommunications network;
while in the idle mode, performing a plurality of MDT (minimization of drive tests) measurements;
logging at least some of said plurality of MDT measurements into a memory of the user equipment to provide logged MDT measurement information, said at least some of said plurality of MDT measurements satisfying a predetermined logging criterion;
entering an active mode, wherein the user equipment is in active communication with the telecommunications network;
sending a message to a network element, said message including an availability indicator, said availability indicator indicating that logged MDT measurement information is available;
receiving a reply message from said network element requesting said logged MDT measurement information; and
sending a response to said network element with at least a portion of said logged MDT measurement information, said response further including said availability indicator indicating that more of said logged MDT measurement information is available.

2. The method as claimed in claim 1 , further comprising:
when said response includes said availability indicator, sending at least one further message to said network element with more of said logged MDT measurement information.

3. The method as claimed in claim 2 , wherein sending at least one further message is repeated until all of said logged MDT measurement information has been sent to said network element.

4. The method as claimed in claim 2 , wherein said at least one further message includes said availability indicator indicating that more of said logged MDT measurement information is available.

5. The method as claimed in claim 2 , wherein sending at least one further message is responsive to a request from said network element for more of said logged MDT measurement information.

6. The method as claimed in claim 1 , further comprising:
sending quantity information to said network element, said quantity information indicating at least one of:
an additional amount of said logged MDT measurement information available, and
a number of messages to said network element over which said logged MDT measurement information is ready to be sent.

7. The method as claimed in claim 6 , wherein said quantity information is sent with said availability indicator indicating that more of said logged MDT measurement information is available.

8. The method as claimed in claim 1 , wherein at least one reply message from said network element includes quantity information, said quantity information indicating at least one of a maximum size of said logged MDT information measurement information to be sent, and a size of a reply message incorporating said logged MDT measurement information, and wherein at least one response is sent in accordance with said quantity information.

9. A computer program product comprising a non-transitory computer-readable storage medium bearing computer program code embodied therein for use with a computer, the computer program code comprising code for performing the method of claim 1 .

10. A method for a network element in a telecommunications network for monitoring network performance, the method comprising:
receiving a message from a user equipment, said message including an availability indicator, said availability indicator indicating that logged MDT (minimization of drive tests) measurement information is available, said logged MDT information being at least some of a plurality of MDT measurements performed by the user equipment, said at least some of said plurality of MDT measurements satisfying a predetermined criterion;
responsive to said message, sending a request to said user equipment for said logged MDT measurement information;
receiving a response from said user equipment with at least a portion of said logged MDT measurement information, said response further including said availability indicator indicating that more of said logged MDT measurement information is available;
when said availability indicator indicates that more of said logged MDT information is available, sending a further request to said user equipment for said more of said logged MDT measurement information; and
receiving a further response from said user equipment with said more of said logged MDT measurement information.

11. An apparatus, said apparatus being a user equipment in a telecommunications network, comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus to:
enter an idle mode, wherein the user equipment is not in active communication with the telecommunications network;
while in the idle mode, perform a plurality of MDT (minimization of drive tests) measurements;
log at least some of said plurality of MDT measurements into said at least one memory to provide logged MDT measurement information, said at least some of said plurality of MDT measurements satisfying a predetermined logging criterion;
enter an active mode, wherein the user equipment is in active communication with the telecommunications network;
send a message to a network element, said message including an availability indicator, said availability indicator indicating that logged MDT measurement information is available;
receive a reply message from said network element requesting said logged MDT measurement information; and
send a response to said network element with a portion of said logged MDT measurement information, said response further including said availability indicator indicating that more of said logged MDT measurement information is available.

12. The apparatus as claimed in claim 11 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to send at least one further message to said network element with more of said logged MDT measurement information, when said response includes said availability indicator.

13. The apparatus as claimed in claim 12 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to repeat sending at least one further message until all of said logged MDT measurement information has been sent to said network element.

14. The apparatus as claimed in claim 12 , wherein said at least one further message includes said availability indicator indicating that more of said said logged MDT measurement information is available.

15. The apparatus as claimed in claim 12 , wherein sending at least one further message is responsive to a request from said network element for more of said logged MDT measurement information.

16. The apparatus as claimed in claim 11 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to send quantity information to said network element, said quantity information indicating at least one of:
an additional amount of said logged MDT measurement information available, and
a number of messages to said network element over which said logged MDT measurement information is ready to be sent.

17. The apparatus as claimed in claim 16 , wherein said quantity information is sent with said availability indicator indicating that more of said logged MDT measurement information is availa
