Abstract
A method for a cellular telecommunications network includes selecting first and second source cells that are co-sited cells associated with first and second antennas, respectively, identifying first neighbor cells of the first cell and second neighbor cells of the second cell, determining that an antenna feed for the second cell is feeding the first antenna by comparing locations of the first neighbor cells to a pointing direction of the first antenna.
Claims19
A method for a cellular telecommunications network, the method comprising:
- selecting first and second source cells that are co-sited cells associated with first and second antennas, respectively;
- identifying first neighbor cells of the first cell from a first neighbor cell list that is retained by a base station serving the first cell and transmitted to UEs within the first cell;
- identifying second neighbor cells of the second cell from a second neighbor cell list that is retained by a base station serving the second cell and transmitted to UEs within the second cell;
- and
- determining that an antenna feed for the second cell is feeding the first antenna by comparing locations of the first neighbor cells to a pointing direction of the first antenna,
- wherein comparing locations of the first neighbor cells to a pointing direction of the first antenna includes determining whether a predetermined portion of neighbor cells of a neighbor cell list of the first cell are behind the first antenna, and
- wherein the predetermined portion is at least 40%.
A network resource controller in a wireless telecommunications network, the controller comprising:
- a memory;
- a processor;
- and
- a computer readable medium with executable instructions stored thereon which, when executed by the processor, perform the following operations:
- selecting first and second source cells that are co-sited cells associated with first and second antennas, respectively;
- identifying first neighbor cells of the first cell from a first neighbor cell list that is retained by a base station serving the first cell and transmitted to UEs within the first cell;
- identifying second neighbor cells of the second cell from a second neighbor cell list that is retained by the base station serving the first cell and transmitted to UEs within the second cell;
- and
- determining that an antenna feed for the second cell is feeding the first antenna by comparing locations of the first neighbor cells to a pointing direction of the first antenna,
- wherein comparing locations of the first neighbor cells to a pointing direction of the first antenna includes determining whether a predetermined portion of neighbor cells of a neighbor cell list of the first cell are behind the first antenna, and
- wherein the predetermined portion is at least 40%.
