Method of MDT information logging and reporting
First Claim
Patent Images
1. A method, comprising:
- detecting a reference event by a user device (UE) in a wireless network;
detecting a problem event by the UE;
logging the problem event and thereby generating a problem event report based on the detected reference event; and
sending the problem event report to a network device, wherein the problem event report provides time information of the problem event that is related to an occurrence of the reference event.

Abstract
A method of MDT information logging and problem event reporting is provided. The method supports provisioning of reference events to enable correlation of system time and the problem occurrence. In one embodiment, a problem event report includes time information directly or indirectly related to a reference event. A method of handling battery condition is also provided. The method supports autonomously suspending or resuming OAM activities in MDT based on predefined battery condition. In one embodiment, a testable battery condition handling is designed for MDT logging.

1. A method, comprising:
-
detecting a reference event by a user device (UE) in a wireless network; detecting a problem event by the UE; logging the problem event and thereby generating a problem event report based on the detected reference event; and sending the problem event report to a network device, wherein the problem event report provides time information of the problem event that is related to an occurrence of the reference event. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A method, comprising:
-
detecting one or more problem events by a user device (UE) in a wireless network; starting a deadline timer associated with the problem events; logging the problem events into a problem event report; and determining whether to discard or keep the logged problem events in the problem event report based on a status of the deadline timer. - View Dependent Claims (10, 11, 12)

13. A method, comprising:
-
monitoring a condition on a battery of a user device (UE) in a wireless network; detecting a low battery condition of the UE; taking an autonomously suspending action on Operations, Administration, and Maintenance (OAM) activities when detecting the low battery condition; and taking an autonomously resuming action on OAM activities when the UE exits the low battery condition. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. The method of 13, further comprising:
logging information of said autonomous suspending action or said autonomous resuming action in a log.
-
21. The method of 13, further comprising:
storing an existing OAM activity log in a persistent memory when the UE is in the low battery condition.
-
22. The method of 13, wherein the said OAM activities is at least one of logging information for network operation purposes, MDT logging, applying certain device configurations related to the said logging, performing measurements and measurement evaluation for the said logging such as radio measurements or positioning measurements.
