Inter-system neighbor cell generating method and device

The present invention discloses a method and apparatus for generating a neighbor cell among a heterologous system for automatically generating different inter-system neighboring cell, shorter generation period, to enhance the accuracy of the results generated. The method comprising: determining a base station cell coverage of each grid in the range of the home system, a first and a second signal strength signal field intensity in a heterologous system; determining the base station cell coverage overlaps the overlapping area inter-system neighboring cells as an alternative inter-system neighboring cells with different base station cell system according to a first alternative signal strength of each grid, a second field strength signal, and a first signal set in advance field corresponding relationship with weighting coefficients corresponding relationship with the second signal strength priority coefficients were determined for each alternative right inter-system neighboring cell weight; weight of each neighboring cell according to a different alternative system to select different weight system neighboring cell, the base station generates the inter-system cell neighbor cell list.
