Enabling reporting of non-real-time MDT measurements
Methods and apparatus for informing a network node of a wireless communication network of the presence of logged measurements are disclosed. A first mobile station performs measurements concerning one or more connectivity aspects for the first mobile station in relation to the wireless communication network and stores the measurements in an internal log, where the measurements are performed according to a reporting configuration for the first mobile station. The first mobile station then sends a notification to the first network node regarding the presence of logged measurements in order to enable the first network node to respond to the notification with a request for a logged measurement report.

5. The method according to claim 1 , wherein the notification comprises an indication of type of access technology used by the first mobile station when gathering data for the report.
6. The method according to claim 1 , further comprising determining when to send the notification based on at least one notification timing criterion.
7. The method according to claim 6 , wherein the notification timing criterion is based on one or more of the following properties: mobile station memory consumption, battery level, availability of measurements and load in network.
8. The method according to claim 1 , further comprising receiving the reporting configuration from a network node.
9. The method according to claim 8 , wherein the network node is the first network node.
10. The method according to claim 8 , wherein the network node is a further network node, where the first and further network nodes use different types of access technology.
11. The method of claim 1 , wherein the reporting configuration further comprises information indicating the extent of time the configuration is valid.
12. A first mobile station operative to inform a first network node of a wireless communication network about the presence of logged measurements, the mobile station comprising:

a control circuit configured to
order the measurements to be performed;
store the measurements in an internal log; and
order a transmitter to send a notification to the first network node regarding the presence of logged measurements in order to enable the first network node to respond to the notification with a request for a logged measurement report, wherein the notification comprises a radio resource control connection setup complete message having a logged measurement indicator.
13. The first mobile station of claim 11 , wherein the reporting configuration further comprises information indicating the extent of time the configuration is valid.
14. The first mobile station of claim 11 , wherein the control circuit is further configured to order a transmitter to repeat sending a notification if no request is received.
15. A computer program product operative to inform a first network node of a wireless communication network about the presence of logged measurements, the computer program product comprising a non-transitory computer readable storage medium comprising a set of instructions causing a control circuit in a mobile station to
order measurements concerning one or more connectivity aspects to be performed in and for the first mobile station in relation to the wireless communication network, the measurements being performed according to a reporting configuration for the first mobile station;
store the measurements in an internal log; and
order a transmitter to send a notification to the first network node regarding the presence of logged measurements in order to enable the first network node to respond to the notification with a request for a logged measurement report, wherein the notification comprises a radio resource control connection setup complete message having a logged measurement indicator.
16. The computer program product of claim 15 , wherein the reporting configuration further comprises information indicating the extent of time the configuration is valid.
17. The computer program product of claim 15 , wherein the instructions further order the transmitter to repeat sending a notification if no request is received.
18. A method of enabling a mobile station to inform a first network node of a wireless communication network of the presence of logged measurements, the method comprising:
determining to provide a first mobile station with a reporting configuration for sending logged measurement reports; and
transmitting, from a network node to the first mobile station, the reporting configuration in order to enable the mobile station to send a notification to the first network node regarding the presence of logged measurements, wherein the notification comprises a radio resource control connection setup complete message having a logged measurement indicator.
19. The method according to claim 18 , wherein the reporting configuration specifies that the first mobile station shall perform measurements when in idle mode.
20. The method of claim 18 , wherein the reporting configuration further comprises information indicating the extent of time the configuration is valid.
21. The method of claim 18 , wherein the reporting configuration further comprises information indicating that, if the mobile station does not receive a request for a logged measurement report from the first network node in response to sending the notification, the mobile station should repeat sending a notification.
22. The method of claim 18 , wherein the method further comprises, in response to the first network node failing to respond to a first notification from the mobile station regarding the presence of logged measurements, receiving a second notification at the first network node from the mobile station regarding the presence of logged measurements.
23. The method of claim 18 , further comprising storing the reporting configuration in memory of the network node for transmitting the reporting configuration.
24. A network node of a wireless communication network operative to enable a first mobile station to inform a first network node of the wireless communication network of the presence of logged measurements, the network node comprising:
a control circuit configured to provide the first mobile station with a reporting configuration for enabling the mobile station to send a notification to the first network node regarding the presence of logged measurements, wherein the notification comprises a radio resource control connection setup complete message having a logged measurement indicator; and
a radio circuit and one or more antennas for transmitting the reporting configuration to the first mobile station.
25. The network node of claim 24 , wherein the reporting configuration further comprises information indicating the extent of time the configuration is valid.
26. The network node of claim 24 , wherein the reporting configuration further comprises information indicating that, if the mobile station does not receive a request for a logged measurement report from the first network node in response to sending the notification, the mobile station should repeat sending a notification.
