Abstract

Systems and methods are disclosed herein for controlling reporting and/or logging of data by a wireless device in a cellular communications network under one or more constraints. In one embodiment, a node in the cellular communications network makes a determination as to whether at least one of logged data logged by a wireless device in a log, data associated with the logged data, data to be logged by the wireless device, and data associated with the data to be logged by the wireless device satisfies one or more constraints. The node then controls at least one of reporting of the log by the wireless device and logging of data in the log by the wireless device in response to the determination.

Claims

1. A method of operation of a node in a cellular communications network, comprising:

making a determination as to whether an elapsed time since logged data was last stored by a wireless device in a log is greater than a first threshold but less than a second threshold; and

attempting to report at least a portion of the log if the elapsed time since the logged data was last stored in the log is one of;

greater than the first threshold but less than the second threshold, or

expected to be greater than the first threshold but less than the second threshold,

thereby improving an ability of the node to provide accurate logged data.

2. The method of claim 1 wherein the logged data is logged measurement data for a Minimization of Drive Test, MDT, log.

3. The method of claim 1 wherein the logged data is logged data for at least one of a radio measurement log, a Radio Resource Control, RRC, connection establishment failure log, a random access failure log, a paging channel failure log, a broadcast channel failure log, and a radio link failure log.

4. The method of claim 1 wherein the logged data comprises at least one of a group consisting of:

a plurality of accessibility measurements, a plurality of positioning measurements, a cell identification, one or more radio environment measurements, a transmit power indication, a contention detection indication, data related to failure of specific channels, data related to radio link failure, statistics related to Timing Advance, TA, measurement, statistics related to TA command, statistics related to timing synchronization, timing measurements, and resource usage by the wireless device for performing one or more tasks.

5. The method of claim 1 further comprising sending capability information to another node, the capability information being related to a capability of the node to make the determination and control at least one of reporting of the log and the logging of data in response to the determination.

6. The method of claim 1 wherein the node is the wireless device.

7. The method of claim 1 wherein the node is a network node of the cellular communications network.

8. A wireless device configured to operate in a cellular communications network, comprising:

a radio subsystem;

memory; and

a processing subsystem associated with the radio subsystem and the memory, the processing subsystem configured to;

make a determination as to whether an elapsed time since logged data was last stored by the wireless device in a log is greater than a first threshold but less than a second threshold; and

attempt to report at least a portion of the log if the elapsed time since the logged data was last stored in the log is one of;

greater than the first threshold but less than the second threshold, or

expected to be greater than the first threshold but less than the second threshold,

thereby improving an ability of the wireless device to provide accurate logged data.
