During the operation of the indoor a system, the RSRP-uplink rate and the SINR-downlink rate are recorded, and interval packet statistics is performed with 1dB (adjustable default) as the step length of RSRP and SINR, and the average value of the uplink rate and the downlink rate of each interval is obtained, so as to generate a performance mapping fingerprint table as shown in the following table 2 (i.e., the first performance mapping fingerprint table in this embodiment). The ratio of the resources allocated by the user is similar if the wireless resource scheduling policy of the system a and the wireless resource scheduling policy of the system B are consistent, the rate of which can be amplified by the bandwidth ratio in equal ratio, and the ratio of the configured bandwidths of the system B and the system a is R (i.e., the preset inter-system broadband ratio in the present embodiment), i.e., the preset inter-system broadband ratio in the present embodiment. From the obtained RSRP value and SINR value of the Z-band of the B-system (in the third report), index table 2 assumes that the uplink rate of the base station in the Z-band of the B-system where the user of the ith sampling point resides is t_u_in _i ＝Map_T(RSRP _{B_Z_i} ) R, downlink rate is: T_D_in _i ＝Map_T(SINR _{B_Z_i} ) R is the first uplink and downlink rate corresponding to the third system frequency band in this embodiment.

T_u_mid is the actual upstream multi-stream rate and t_d_mid is the actual downstream multi-stream rate. The Mids will generate a plurality of second performance mapping fingerprint tables, and index table 3 of the obtained RSRP value and SINR value of the Y-band of the B-system assumes that the uplink rate of the indoor base station of the Y-band of the B-system where the user of the ith sampling point resides is T_U_macro _i ＝Map_T(RSRP _{B_Y_i_Mid} ) The downlink rate is T_D_macro _i ＝Map_T(SINR _{B_Y_i_Mid} ).

Setting an uplink rate standard as S_U, setting a downlink rate standard as S_D, and if the condition of judging whether to deploy the B system Z frequency band indoor base station is that the uplink rate meets the preset condition and the downlink rate meets the preset condition, not deploying the B system Z frequency band indoor base station under the conditions of P_5% (T_U_macro) > S_U and P_5% (T_D_macro) > S_D. It can be understood that the factor for evaluating the deployment necessity of the indoor base station in the new system frequency band can also be uplink air interface time delay, downlink air interface time delay and other specific service satisfaction.

Specifically, for the ith sampling point, the value of RSRP in the B system Y band is a known measurement value, and the strongest value of the outdoor signal in the B system Y band in the second report is RSRP _{B_Y_i_1_Mid} The B system Y frequency band SINR value of the sampling point isAnd in the measurement period, continuously operating the peripheral outdoor base stations with the number Mid, recording an RSRP value-uplink rate and an SINR-downlink rate for each outdoor base station with the number Mid, taking an adjustable default value as a step length of the RSRP and the SINR, carrying out interval grouping statistics, and taking an average value of the uplink rate and the downlink rate of each interval to generate a second performance mapping fingerprint table shown in the table 3.

Specifically, the present embodiment relates to percentile value taking of a set of arrays, such as a median (e.g., 50% of the quantile), an edge (e.g., 5% of the quantile), and the like, where the percentile value taking is performed as p_x% (V), x is a percentile, x belongs to a preset edge interval in the present embodiment, and V is an array. The conditions for judging whether the B system Z frequency band indoor base station is deployed or not include that only the uplink rate meets the preset condition, only the downlink rate meets the preset condition, the uplink rate meets the preset condition and the downlink rate meets the preset condition, and the uplink rate meets the preset condition or the downlink rate meets the preset condition. The uplink rate standard is set as s_u (i.e., the preset uplink rate standard in the terminal of the embodiment), the downlink rate standard is s_d (i.e., the preset downlink rate standard in the terminal of the embodiment), and if the condition of judging whether to deploy the B system Z frequency band indoor base station is that the uplink rate satisfies the preset condition or the downlink rate satisfies the preset condition, if p_5% (t_u_macro) > s_u, or p_5% (t_d_macro) > s_d), the B system Z frequency band indoor base station is not deployed.

and step S560, revising the first uplink and downlink rates corresponding to the third system frequency band according to the number of channels of the indoor equipment to obtain revised uplink and downlink rates corresponding to the deployed third system frequency band.

Specifically, assuming that the Z-band of the B-system needs to be deployed, the uplink indoor coverage counter is set to be count_u, the downlink indoor coverage counter is set to be count_d, initial values of count_u and count_d are set to be 0, and when t_u_macro is set to be _i <When S_U, count_U is increased by 1, and when T_D_macro _i <When S_D is performed, the Count of count_D is incremented by 1, and S (i.e. the total number of sampling points in the embodiment) sampling points are traversed to obtain the value of count_U and the value of count_D, i.e. the number of sampling points in the embodiment.

As can be seen, considering that the coverage wireless environment of the indoor base station is better, the first downlink rate corresponding to the Z frequency band of the B system can be revised according to the number of channels of the actually deployed device, that is, if the number of channels of the indoor base station is N, the downlink rate value of the sampling point of the indoor base station in the Z frequency band of the B system is revised to be t_d_in_n ₁ ＝T_D_in ₁ * N, i.e. the revised uplink and downlink rates in this embodiment.

According to the embodiment, the indoor base station deployment result corresponding to the new system frequency band is determined through the uplink and downlink rate standard and the new system deployment condition, so that the evaluation and test efficiency of the indoor base station deployment of the new system frequency band is improved, and the necessity of the indoor base station deployment of the new system frequency band is fully evaluated.
