Abstract

Claims (56)

1 . A method of identifying call muting areas, the method comprising:

dividing a network cluster into a plurality of grids;

determining a call muting percentage of at least one first grid of the plurality of grids, the call muting percentage indicating a percentage of calls in which voice data packets are dropped but the calls remain connected during dropping of the voice data packets;

determining whether the call muting percentage of the at least one first grid is greater than a predetermined call muting percentage threshold; and

generating at least one call muting polygon comprising at least a portion of the at least one first grid based on determining that the call muting percentage of the at least one first grid is greater than the predetermined call muting percentage threshold.

2 . The method of claim 1 , wherein the call muting percentage of the at least one first grid is determined based on drive test data comprising call muting key performance indicator (KPI) of user equipments (UEs) in the at least one first grid, the call muting KPIs indicating calls in which the voice data packets are dropped during the calls such that the calls remain connected during the dropping of the voice data packets.

3 . The method of claim 1 , further comprising:

determining a unique user percentage of the at least one first grid based on a first number of unique users in the at least one first grid and a second number of unique users in the network cluster; and

assigning a priority level to the at least one first grid based on the unique user percentage of the at least one first grid.

4 . The method of claim 3 , wherein assigning the priority level comprises assigning a high priority level based on the unique user percentage of the at least one first grid being greater than a predetermined unique user percentage threshold.

5 . The method of claim 3 , wherein assigning the priority level comprises assigning a low priority level based on the unique user percentage of the at least one first grid being less than a predetermined unique user percentage threshold.

6 . The method of claim 1 , further comprising, based on determining that the call muting percentage of the at least one first grid is greater than the predetermined call muting percentage threshold:

determining a call muting percentage of at least one second grid of the plurality of grids, the at least one second grid neighboring the at least one first grid; and

determining whether the call muting percentage of the at least one second grid is greater than the predetermined call muting percentage threshold,

wherein the at least one call muting polygon comprises a same polygon including the at least the portion of the at least one first grid and at least a portion of the at least one second grid based on determining that the call muting percentage of the at least one second grid is greater than the predetermined call muting percentage threshold.

7 . The method of claim 1 , further comprising:

dividing the network cluster into a plurality of tiles; and

obtaining morphology data corresponding to the plurality of tiles.

8 . The method of claim 7 , further comprising:

determining, based on the morphology data, that at least one tile of the plurality of tiles comprises a morphology that indicates that data sets obtained from grids within the at least one tile are to be discarded;

determining that at least one grid of the plurality of grids is within the at least one tile; and

discarding data sets corresponding to the at least one grid that is within the at least one tile.

9 . A system for identifying call muting areas, the system comprising:

divide a network cluster into a plurality of grids;

determine a call muting percentage of at least one first grid of the plurality of grids, the call muting percentage indicating a percentage of calls in which voice data packets are dropped but the calls remain connected during dropping of the voice data packets;

determine whether the call muting percentage of the at least one first grid is greater than a predetermined call muting percentage threshold; and

generate at least one call muting polygon comprising at least a portion of the at least one first grid based on determining that the call muting percentage of the at least one first grid is greater than the predetermined call muting percentage threshold.

10 . The system of claim 9 , wherein the call muting percentage of the at least one first grid is determined based on drive test data comprising call muting key performance indicator (KPI) of user equipments (UEs) in the at least one first grid, the call muting KPIs indicating calls in which the voice data packets are dropped during the calls such that the calls remain connected during the dropping of the voice data packets.

11 . The system of claim 9 , wherein the at least one processor is further configured to execute the instructions to:

determine a unique user percentage of the at least one first grid based on a first number of unique users in the at least one first grid and a second number of unique users in the network cluster; and
