Embodiment 1

[0038] The embodiment of the present invention first proposes: based on the signal field strength simulation results, the generation of adjacent cells between different systems is realized. Use the signal field strength simulation module to determine the signal field strength of each grid in the coverage area of ​​the base station cell in the home system and the different system; determine the alternative different system adjacent cells, and consider each alternative different system adjacent cell For the overlapping area of ​​the base station cells, determine the weight of each candidate different-system adjacent cell; select the different-system adjacent cell according to the weight of the candidate different-system adjacent cell, and generate a list of different-system adjacent cells of the base station cell.

[0039] Such as figure 1 As shown, the embodiment of the present invention provides an apparatus for generating adjacent cells between different systems, including: ...

Embodiment 2

[0129] On the basis of the solution provided by the first embodiment, the embodiment of the present invention further proposes: on the premise of the signal field strength simulation results, the generation of adjacent cells between different systems is realized in combination with the geographical conditions of the base station.

[0130] Such as Figure 8 As shown, the embodiment of the present invention provides another method for generating adjacent cells between different systems, including the following steps:

[0131] S801. Determine the first signal field strength in the home system and the second signal field strength in the foreign system of each grid within the cell coverage of the base station;

[0132] S802. Determine that the different-system cell overlapping with the coverage of the base station cell is a candidate different-system adjacent cell, according to the first signal field strength and the second signal field strength of each grid in the overlapping area...

Abstract

The invention discloses an inter-system neighbor cell generating method and an inter-system neighbor cell generating method, which are used for automatically generating the inter-system neighbor cells, shortening a generation period and improving the accuracy of a generation result. The method comprises the following steps of: determining the first signal field intensity in an attribution system and the second signal field intensity in an inter-system of each grid in a coverage range of a base station cell; determining a cell of a foreign system having the same coverage range as the base station cell as a candidate foreign system neighbor cell and determining the weight of each candidate foreign system neighbor cell respectively according to the first signal field intensity and the second signal field intensity of each grid in the superposed area of the candidate foreign system neighbor cell and the base station cell, the preset correspondence between the first signal field intensity and weighing coefficient and the preset correspondence between the second signal field intensity and priority coefficient; and selecting the foreign system neighbor cell according to the weight of each candidate foreign system neighbor cell and generating a foreign system neighbor cell list of the base station cell.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for generating adjacent cells between different systems. Background technique [0002] At present, the digital mobile communication system with the largest commercial scale and the widest coverage in the world is GSM (Global System for Mobile Communication, Global System for Mobile Communication). The GSM system is generally called the 2G (the 2nd Generation Mobile Communication, second-generation mobile communication) system, and the CDMA (Code Division Multiple Access, Code Division Multiple Access) system also belongs to the 2G system. With the development of technology, the 3G (The 3rd Generation Mobile Communication, third generation mobile communication) system has also entered or will enter the commercial stage. The 3G system takes WCDMA (Wideband CDMA) standard, TD-SCDMA (Time Division-Synchronous CDMA) standard and CDMA2000 stand...
