Abstract
A method and apparatus for detecting and determining the location of a coverage hole in a communications network such as a cellular communication system wherein the location is determined from operational parameters and/or by network elements themselves. Additionally is a method to reduce a hole by adjusting antennae parameters preferably remotely and automatically and this can be done in conjunction with hole location to optimise the system.

-51. (canceled)
A method, comprising:
- detecting and determining a location of a coverage hole in a communications network, wherein said location is determined from at least one of operational parameters and by network elements themselves,
- where it is determined that a coverage hole is located between at least two adjacent base stations providing at least two adjacent cells when radio link failures increase in the at least two adjacent cells.
An apparatus comprising a data processor connected with a memory that stores computer program instructions for execution by the data processor to cause the data processor to detect and determine a location of a coverage hole in a communications network, wherein said location is determined from at least one of operational parameters and by network elements themselves, and where it is determined that a coverage hole is located in the vicinity of, or between, at least two adjacent base stations providing at least two adjacent cells when radio link failures increase in the at least two adjacent cells.
A method, comprising:
- reducing or eliminating a coverage hole in, or optimizing, a communication network having at least one base station by modifying radio patterns of one or more antenna of said at least one base station, where modifying radio patterns comprises changing at least one of tilt, gain, beam-width, horizontal or vertical radio patterns of the one or more antenna;
- and
- determining a change in network performance as a result of said modification.
An apparatus comprising a data processor connected with a memory that stores computer program instructions for execution by the data processor to cause the data processor to reduce or eliminate a coverage hole in, or optimize, a communication network having at least one base station by remotely modifying radio patterns of one or more antenna of said at least one base stations where remotely modifying radio patterns comprises changing at least one of tilt, gain, beam-width, horizontal or vertical radio patterns of the one or more antenna;
- and to determine a change in network performance as a result of said modification.
