Abstract

A network receives from a user equipment UE information about a measurement configuration used to log test measurements; and the network uses the received information to determine further signaling to send to the UE concerning further test measurements. The network can compare the received measurement configuration to a measurement configuration for the further test measurements; and if the same can merely indicate to the UE to continue using the same configuration else if different can indicate to the UE the new configuration to use for the further measurements. The UE logs the test measurements taken in the IDLE mode. After exiting the IDLE mode it sends to the network with which it connects information about the measurement configuration used to collect the measurements. The information can be sent in a RRC Connection Setup Complete message along with an availability indictor that the logged test measurements are available.

Claims

1. A method, comprising:

receiving from a user equipment information about measurement configuration used to log test measurements; and

using the received information to determine further signaling to send to the user equipment concerning further test measurements.

2. The method according to claim 1, in which using the received information comprises comparing the measurement configuration for which the information was received to a measurement configuration for the further test measurements.

3. The method according to claim 2, in which:

if the comparing finds the measurement configuration for which the information was received is the same as the measurement configuration for the further test measurements, then the further signaling comprises an indication for the user equipment to continue using the measurement configuration for which the information was received for the further test measurements; and

if the comparing finds the measurement configuration for which the information was received is different than the measurement configuration for the further test measurements, then the further signaling comprises an indication of the different measurement configuration for the further test measurements.

4. The method according to claim 1, further comprising sending to the user equipment, after receiving the information about the measurement configuration used to log the test measurements, a request for the user equipment to send the logged test measurements.

5. The method according to claim 1, in which the information is received in a RRC Connection Setup Complete message and the further signaling is sent after receiving the logged test measurements.

6. An apparatus, 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 to, with the at least one processor, cause the apparatus at least to;

receive from a user equipment information about a measurement configuration used to log test measurements; and

use the received information to determine further signaling to send to the user equipment concerning further test measurements.

7. The apparatus according to claim 6, in which the at least one memory and the computer program code is configured to, with the at least one processor, cause the apparatus to use the received information by at least comparing the measurement configuration for which the information was received to a measurement configuration for the further test measurements.

8. The apparatus according to claim 7, in which:

if the comparing finds the measurement configuration for which the information was received is the same as the measurement configuration for the further test measurements, then the further signaling comprises an indication for the user equipment to continue using the measurement configuration for which the information was received for the further test measurements; and

if the comparing finds the measurement configuration for which the information was received is different than the measurement configuration for the further test measurements, then the further signaling comprises an indication of the different measurement configuration for the further test measurements.

9. The apparatus according to claim 6, in which the at least one memory and the computer program code is configured to, with the at least one processor, cause the apparatus to further send to the user equipment, after receiving the information about the measurement configuration used to log the test measurements, a request for the user equipment to send the logged test measurements.

10. The apparatus according to claim 6, in which the information is received in a RRC Connection Setup Complete message and the further signaling is sent after receiving the logged test measurements.

11. A computer readable memory storing a program of computer readable instructions that when executed by a processor result in actions comprising:

receiving from a user equipment information about a measurement configuration used to log test measurements; and

using the received information to determine further signaling to send to the user equipment concerning further test measurements.

12. The computer readable memory according to claim 11, in which using the received information comprises comparing the measurement configuration for which the information was received to a measurement configuration for the further test measurements.

13. A method, comprising:

logging in a local memory test measurements taken according to a measurement configuration while a user equipment is in an IDLE mode; and

after exiting the IDLE mode and connecting to a network, sending to the network information about the measurement configuration.

14. The method according to claim 13, in which the information about the measurement configuration is sent in a message that carries an indication that the logged test measurements are available.

15. The method according to claim 14, in which the message is a RRC Connection Setup Complete message.

16. The method according to claim 13, executed by the user equipment, the method further comprising:

after reporting the logged test measurements to the network, receiving from the network an indication to log further test measurements using the said measurement configuration.

17. An apparatus 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 to, with the at least one processor, cause the apparatus at least to;

log in a local memory test measurements taken according to a measurement configuration while a user equipment is in an IDLE mode; and

after exiting the IDLE mode and connecting to a network, send to the network information about the measurement configuration.

18. The apparatus according to claim 17, in which the information about the measurement configuration is sent in a message that carries an indication that the logged test measurements are available.

19. The apparatus according to claim 18, in which in which the message is a RRC Connection Setup Complete message.

20. The apparatus according to claim 17, in which the apparatus comprises the user equipment,

in which the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least further to:

report the logged test measurements to the network;

and after reporting the logged test measurements to the network, receive from the network an indication to log further test measurements using the said measurement configuration.
