Abstract

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.

Claims

1. A method of informing a first network node of a wireless communication network of the presence of logged measurements from a first mobile station, the method comprising:

performing measurements concerning one or more connectivity aspects 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, and

storing the measurements in an internal log, and sending 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.

2. The method according to claim 1, further comprising repeating sending a notification if no request is received.

3. The method according to claim 1, wherein measurements are retained in the internal log if no request is received.

4. The method according to claim 1, wherein the performing of measurements is made in idle mode.

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, wherein the notification is sent as a radio resource control message.

7. The method according to claim 6, wherein the radio resource control message is a modified message relating to the connection of a mobile station to the network.

8. The method according to claim 7, wherein the message is a radio resource control connection setup complete message.

9. The method according to claim 1, further comprising determining a point in time when to send the notification based on at least one notification timing criterion.

10. The method according to claim 9, 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.

11. The method according to claim 1, further comprising receiving the reporting configuration from a network node.

12. The method according to claim 11, wherein the network node is the first network node.

13. The method according to claim 12, wherein the network node is a further network node, where the first and further network nodes use different types of access technology.

14. A first mobile station for informing a first network node of a wireless communication network about the presence of logged measurements, the mobile station comprising:

a measurement performing unit for performing measurements concerning one or more connectivity aspects 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, and

a control unit arranged 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.

15. A computer program product for informing a first network node of a wireless communication network about the presence of logged measurements, the computer program product comprising a computer readable storage medium comprising a non-transitory set of instructions causing a control unit 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, and

store the measurements in an internal log, and order a transmitter to send a notification to the first network node regarding the presence of a logged measurements in order to enable the first network node to respond to the notification with a request for a logged measurement report.

16. A method of enabling a mobile station to inform a first network node of the wireless communication network of the presence of logged measurements, the method comprising the step of providing, from a network node, a first mobile station with a reporting configuration for sending logged measurement reports in order to enable the mobile station to send a notification to the first network node regarding the presence of logged measurements.

17. The method according to claim 16, wherein the reporting configuration specifies that the first mobile station shall perform measurements when in idle mode.

18. A network node of a wireless communication network for enabling 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 processor arranged 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.

19. A computer program product for enabling a mobile station to inform a first network node of the wireless communication network of the presence of logged measurements, the computer program product comprising a computer readable storage medium comprising a non-transitory set of instructions causing a network node in the network to:

provide a 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.
