Method of MDT information logging and reporting
First Claim
Patent Images
1. A method, comprising:
- detecting, by a user equipment (UE), a reference event in a wireless network, the reference event being a common event known to the UE and a network device;
detecting a problem event by the UE;
determining, by the UE, a duration between an occurrence of the reference event and an occurrence of the problem event; and
sending, by the UE to the network device, a problem event report to report the detected problem event, the problem event report including relative time information indicating the determined duration,wherein the method further comprises;
detecting, by the UE, whether a battery of the UE is in a low-battery condition;
suspending the sending the problem event report in response to detection of the battery of the UE being in the low-battery condition; and
resuming the sending the problem event report after the battery of the UE exits the low-battery condition, andwherein the problem event report further includes a delayed report indicator that is added to indicate whether the sending the problem event report is delayed.

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, by a user equipment (UE), a reference event in a wireless network, the reference event being a common event known to the UE and a network device; detecting a problem event by the UE; determining, by the UE, a duration between an occurrence of the reference event and an occurrence of the problem event; and sending, by the UE to the network device, a problem event report to report the detected problem event, the problem event report including relative time information indicating the determined duration, wherein the method further comprises; detecting, by the UE, whether a battery of the UE is in a low-battery condition; suspending the sending the problem event report in response to detection of the battery of the UE being in the low-battery condition; and resuming the sending the problem event report after the battery of the UE exits the low-battery condition, and wherein the problem event report further includes a delayed report indicator that is added to indicate whether the sending the problem event report is delayed. - View Dependent Claims (2, 3, 4, 5)

6. A user equipment (UE), comprising:
-
a processing circuit configured to; detect a reference event in a wireless network, the reference event being a common event known to the UE and a network device; detect a problem event; and determine a duration between the occurrence of the reference event and an occurrence of the problem event; and a transceiver configured to send a problem event report to the network device to report the detected problem event, the problem event report including relative time information indicating the determined duration, wherein the processing circuit is further configured to; detect whether a battery of the UE is in a low-battery condition; suspend the sending the problem event report in response to detection of the battery of the UE being in the low-battery condition; and resume the sending the problem event report after the battery of the UE exits the low-battery condition, and wherein the problem event report further includes a delayed report indicator that is added to indicate whether the sending the problem event report is delayed. - View Dependent Claims (7, 8, 9, 10)
