Minimum drive test (MDT) log availability indicator with data information
A mobile wireless communication user equipment device (mobile device) transmits, to a base station, a log size of an available Minimization of Drive Test (MDT) log. In at least one example, the log size is included as part of a log availability indicator indicating the availability of the MDT log. The base station determines whether to retrieve the MDT log based at least partially on the log size. In addition, the mobile device can send MDT data type indicator indicative of at least one type of data logged during the MDT where the base station can further base the decision on whether to retrieve the MDT log on the MDT data type indicator.
1. A mobile wireless communication device comprising:
a memory;
a receiver configured to receive a Minimization of Drive Test (MDT) configuration;
a controller configured to perform an MDT in accordance with the MDT configuration, log results of the MDT in the memory as an MDT log, and determine a log size of the MDT log;
a transmitter configured to transmit, to a base station, a log availability indicator indicating the availability of the MDT log, indicating the log size, and comprising a type of data indicator indicative of MDT data included in the MDT log, wherein the type of data indicator is indicative of MDT data corresponding to at least one of a mobile device orientation, a Synchronization Signal Block (SSB) Index of a best beam, a received signal quality of the best beam, an out-of-coverage condition indicator indicative of whether an out-of-coverage condition occurred during the MDT, or a cell identifier identifying at least one cell included in the MDT log.
2. The mobile wireless communication device of claim 1 , wherein:
the receiver is further configured to receive a log retrieval request from the base station; and
the transmitter is further configured transmit the MDT log report indicative of the MDT log to the base station in response to the log retrieval request.
3. A method comprising:
receiving, at a mobile communication device, a Minimization of Drive Test (MDT) configuration;
perform an MDT in accordance with the MDT configuration;
logging results of the MDT as an MDT log;
determining a log size of the MDT log;
transmitting, to a base station, a log availability indicator indicating the availability of the MDT log, indicating the log size, and comprising an MDT data type indicator indicative of at least one type of data logged during the MDT, wherein the MDT data type indicator is indicative of MDT data corresponding to at least one of a mobile device orientation, a Synchronization Signal Block (SSB) Index of a best beam, a received signal quality of the best beam, an out-of-coverage condition indicator indicative of whether an out-of-coverage condition occurred during the MDT, or a cell identifier identifying at least one cell included in the MDT log.
4. The method of claim 3 , further comprising:
receiving a log retrieval request from the base station; and
transmitting the MDT log report indicative of the MDT log to the base station in response to the log retrieval request.
5. Communication system infrastructure comprising:
a receiver configured to receive, from a mobile device, a log availability indicator indicating the availability of a Minimization of Drive Test (MDT) log, indicating a log size of the MDT log, and comprising an MDT data type indicator indicative of at least one type of data logged during the MDT, wherein the MDT data type indicator is indicative of MDT data corresponding to at least one of a mobile device orientation, a Synchronization Signal Block (SSB) Index of a best beam, a received signal quality of the best beam, an out-of-coverage condition indicator indicative of whether an out-of-coverage condition occurred during the MDT, or a cell identifier identifying at least one cell included in the MDT log;
a controller configured to determine, based at least partially on the log size, whether to retrieve the MDT log from the mobile device; and
a transmitter configured to transmit a log retrieval request to the mobile device in response to a determination to retrieve the MDT log.
6. The communication system infrastructure of claim 5 , wherein
the controller is further configured to determine whether to retrieve the MDT log based at least partially on the MDT data type indicator.
7. The communication system infrastructure of claim 5 , wherein the transmitter and receiver are part of a base station.
8. The communication system infrastructure of claim 7 , wherein the controller is part of a base station.
9. The communication system infrastructure of claim 7 , wherein the controller is part of a Trace Entity (TCE) in a core network connected to the base station.
10. A method comprising:
receiving, from a mobile device, a log availability indicator indicating the availability of a Minimization of Drive Test (MDT) log, indicating a log size of the MDT log, and comprising an MDT data type indicator indicative of at least one type of data logged during the MDT, wherein the MDT data type indicator is indicative of MDT data corresponding to at least one of a mobile device orientation, a Synchronization Signal Block (SSB) Index of a best beam, a received signal quality of the best beam, an out-of-coverage condition indicator indicative of whether an out-of-coverage condition occurred during the MDT, or a cell identifier identifying at least one cell included in the MDT log;
determining, based at least partially on the log size, whether to retrieve the MDT log from the mobile device; and
a transmitting a log retrieval request to the mobile device in response to a determination to retrieve the MDT log.
11. The method of claim 10 , further comprising determining whether to retrieve the MDT log based at least partially on the MDT data type indicator.
