Method and apparatus for optimization of a cellular network
InactiveUS6999766B1Radio/inductive link selection arrangementsSubstation equipmentStatistical ReportPaging
A method and apparatus for optimizing system parameters in a cellular communication network. Pilot strength measurement messages (PSMMs) that are received by bases stations of the network to be optimized are saved in a database. The database accumulates the raw data contained in the pilot strength measurement messages. After a sufficient amount of data has been collected, a report generator compiles a statistics report for each base station based on the raw PSMM data. The present invention then provides a method for applying the information in the report in order to optimize the network parameters of the cellular system. The neighbor list which is transmitted on the paging or traffic channel is revised in accordance with the compiled statistics. The antenna tilt of the base stations is adjusted in accordance with the compiled statistics.

Using High-beam and low-beam transmission signals that have different antenna tilts, different beam-widths, and different polarizations than one another may provide performance advantages in wireless networks. The high-beam transmission signal and the low-beam transmission signal may have orthogonal polarizations. For example, the high-beam transmission signal and the low-beam transmission signal may be linearly polarized signals having different electromagnetic field (E-field) polarization angles with respect to the y-axis, e.g., + / − forty-five degrees with respect to a vertically polarized wave. As another example, the high-beam transmission signal may be a vertically polarized signal, and the low-beam transmission signal may be a horizontally polarized signal, or vice-versa. In addition to having orthogonal polarizations, the low-beam transmission signal may have a greater antenna beam down-tilt angle, and a wider beam-width than the high-beam transmission signal.
