Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
Because existing GSM C/I interference matrix mainly utilizes MR data construct.But existing MR data exist a problem: in the adjacent area inventory that mobile phone reports, the interfere information of the community of same BCCH (Broadcast Control Channel, Broadcast Control Channel) can not be reported with Serving cell exactly.But this kind of interfere information really exists, thus cause constructed GSM C/I interference matrix not comprehensively with accurate.
In the present invention, when building GSM C/I interference matrix, utilizing the topological structure derivation of system go out the interference relationships between sector and quantize, fundamentally solving and disturbing by such systematic error introduced, in later stage Site Service implementation process, for planning and the optimization of system frequency.
Concrete, when user calls, the factor affecting speech quality is exactly the interference of around adjacent cell and adjacent cell generation, if a certain adjacent cell is configured with identical BCCH with the Serving cell in call, this adjacent cell increases with intensity and strengthens the interference effect of Serving cell, and then cause the conversational speech Quality Down of Serving cell, even call drop.And for preparing the mobile subscriber switching to this Serving cell, due to co-channel interference, cause and cannot untie BSIC (Base Station Identity Code, base station identity code), this kind of impact should obtain considering (numerical quantization) in calculating C/I interference matrix.As shown in Figure 1, Serving cell BCCH18, BSIC27, have five adjacent cells, N1, N2, N3N4 and N5, and Serving cell may be subject to the interference with it with BCCH community, interfered cell BCCH18 as shown in the figure, BSIC26.
In the cellphone subscriber's measurement report data collected, there will not be and the relevant information of Serving cell with interfered cell frequently, generate in computational process at C/I interference matrix, the influencing factor of this part co-channel interference, is mostly slipped, and causes the error of correlation between internal system sector, thus affect the quality of frequency planning, reduce the effect of system optimization.
Consider the necessary being of this part factor, need to find out corresponding quantization scheme, since can not get in measurement report MR and the relevant information of Serving cell with the nearby sectors of BCCH, conversion map ralation method can be utilized, by Serving cell and the public adjacent cell with its inter-frequency interference cell both sides, utilize these two with the public adjacent cell of BCCH sector, and the correlation between them, derive and have two of common adjacent area with frequency inter-sector interference relation, be similar to the mapping method of looking in the mirror, the interference relationships of rediscover.Introduce GSM frequency optimization method provided by the invention below in detail, comprise the following steps:
S1, obtains the measurement report MR generated when cellphone subscriber converses in test zone;
