What deserves to be explained is, WCDMA signal is the GSM frequency employing refarming.
For OMC equipment 203, as shown in Figure 3, the invention provides a kind of planing method of frequency, the method is as follows:
301, determine to disturb frequency point sets, the frequency in interference frequency point sets is the frequency WCDMA signal in refarming-WCDMA network design district being caused to interference.
Wherein, the frequency in the interference frequency point sets obtained in this step is the frequency determining to cause the WCDMA signal in refarming-WCDMA network design district interference from domain space.
302, determine the set of core interference base station, base station in the set of core interference base station is the base station to be determined meeting disturbed condition, and disturbed condition is for screening the base station of all signals in refarming-WCDMA network design district being caused to interference be in refarming-WCDMA network design district and buffering area.
All signals in refarming-WCDMA network design district comprise WCDMA signal and GSM signal.
The base station obtained in this step in the set of core interference base station determines that the WCDMA signal deployed in refarming-WCDMA network design district may cause the base station that the frequency of interference is corresponding from geographical space.Namely the base station determining to meet disturbed condition all belongs to the base station in the set of core interference base station.
303, from the set of core interference base station, determine the target BS set of the frequency disposed in interference frequency point sets.
304, determine to replace frequency point sets, the frequency in displacement frequency point sets is be in the frequency in refarming-WCDMA network design district and buffering area, the WCDMA signal in refarming-WCDMA network design district not being caused to interference.
305, adopt the frequency in displacement frequency point sets to replace interference frequency corresponding to each target BS in target BS set.
The planing method of the frequency that the embodiment of the present invention provides, signal in GSM network to cause co-channel interference problem to WCDMA network is solved with adopting the mode of buffering area in prior art, but in refarming-WCDMA network, when frequency resource is nervous, existing between WCDMA network and GSM network needs adjacent frequency to dispose, cause occurring that adjacent frequency is disturbed between the signal in WCDMA network and the signal in GSM network, thus the problem having influence on the signal quality of refarming-WCDMA network is compared, the present invention is by determining the interference frequency point sets WCDMA signal in refarming-WCDMA network design district being caused to interference, with determine to be in refarming-WCDMA network design district and buffering area the core interference base station set disposed and the base station to be determined of interference may be caused to be formed to the WCDMA signal in refarming-WCDMA wet end administration district network, then from this core interference base station set, obtain the target BS set of the frequency disposed in interference frequency point sets, adopting to be in refarming-WCDMA network design district and buffering area does not cause the frequency of interference to replace interference frequency corresponding to each target BS in target BS set to the WCDMA signal in refarming-WCDMA network design district, thus in refarming-WCDMA network, the adjacent frequency can eliminated between the signal in WCDMA network and the signal in GSM network is disturbed.
Here it should be noted that, realize in refarming-WCDMA network by above-mentioned steps 301-step 304 in the present invention, the executive agent can eliminating the object that the adjacent frequency between the signal in WCDMA network and the signal in GSM network is disturbed is not limited to OMC equipment.Also can be one and independently be specifically designed to the frequency planning apparatus carrying out frequency and plan to eliminate the adjacent frequency between the signal in WCDMA network and the signal in GSM network and disturb.As shown in Figure 4, the present invention is also applicable to the planning system 30 of another kind of frequency, and this system 30 also comprises frequency planning apparatus 204.
Its intermediate-frequeney point planning apparatus 204, also for receive OMC equipment 203 send from MSC 201 obtain for replace interference frequency information, displacement result is generated by the information of this displacement interference frequency, and displacement result is sent to OMC equipment 203, so that this displacement result is transmitted to BSC 2021 by OMC equipment 203 again.
In order to understand conveniently, executive agent of the present invention is described for OMC equipment.
Further, in step 301, OMC equipment determines that interference frequency point sets comprises:
OMC equipment distributes according to the frequency of the WCDMA network in refarming-WCDMA network design district, determines the frequency that may cause interference to the WCDMA signal in refarming-WCDMA network.Usually, each two frequency bins be close in the bandwidth both sides of refarming-WCDMA network is as frequency WCDMA signal being caused to interference.Such as, the WCDMA network of 3.8MHz takies the GSM frequency (WCDMA signal) of 19 refarming.Represent the set of the GSM frequency of the refarming shared by refarming-WCDMA network with FW, namely FW comprises 19 frequencies.Suppose FW={K, K+1 ..., K+18}, then can obtain FI={K-2, K-1, K+19, K+20}.Wherein FI represents this interference frequency point sets, and K represents the frequency point number of the GSM frequency of refarming, when such as, WCDMA network center carrier frequency in refarming-WCDMA network design district selects base station down 957MHz/ up 912MHz, and K=101.Be understandable that, as K=101, frequency point number be 99,100,120,121 frequency be frequency point number as 101 interference frequency.
Further, in step 302, as shown in Figure 5, the set of OMC equipment determination core interference base station comprises:
3021, OMC equipment obtains the first measurement report (Measurement Report, MR) data corresponding to GSM network user.
GSM network user is used for substituting the WCDMA network user and obtains the base station of WCDMA signal being caused to interference.The user profile that can obtain the GSM network user in refarming-WCDMA network design district in GSM network used in the present invention, can obtain the user profile in WCDMA network the WCDMA network user in refarming-WCDMA network design district.User profile can comprise the identification code of community, the signal level of community.The present invention is for solving the problem eliminated the adjacent frequency between signal in WCDMA network and the signal in GSM network and disturb, and base station corresponding to the GSM frequency having carried out refarming in refarming-WCDMA network can be GSM network user and WCDMA network user's service simultaneously, therefore, use GSM network user to obtain the user profile of GSM network, the base station may causing disturbed condition in refarming-WCDMA network design district and buffering area to all signals can be got.
One MR data comprise the identification code of the main plot of each GSM network user corresponding X the strongest adjacent cell, the signal level of the X the strongest adjacent cell, wherein X be greater than 0 integer.
First OMC equipment obtains BCCH corresponding to each community (Broadcast Control Channel, Broadcast Control Channel) and BSIC (Base Station Identity Code, base station identity code), then OMC equipment passes through BCCH and BSIC corresponding to each community, obtain the identification code of main plot of each GSM network user, the signal level of main plot, thus the identification code of X adjacent cell the strongest, the signal level of the X the strongest adjacent cell that the main plot obtaining each GSM network user is corresponding.The present invention does not limit the concrete value of X, and such as X can be 6.
3022, OMC equipment judges whether X the signal level of the strongest adjacent cell that each GSM network user is corresponding and the difference of GSM adjacent frequency power leakage loss are more than or equal to adjacent frequency determining interference thresholding.
Adjacent frequency determining interference thresholding is for judging whether the signal of adjacent cell causes adjacent frequency to disturb to the signal of main plot.
The obtain manner of adjacent frequency determining interference thresholding has two kinds in the present embodiment.
The first obtain manner, OMC equipment receives the adjacent frequency determining interference thresholding of input.Be understandable that, the adjacent frequency determining interference thresholding of this input is a technical experience value (as-95dBm).
The second obtain manner, OMC equipment obtains the 2nd MR data.2nd MR data comprise received signal code power corresponding to each refarming-WCDMA network user (Received Signal Code Power, RSCP) sample point; The RSCP sample point corresponding to each refarming-WCDMA network user carries out cumulative distribution function curve, determines that adjacent frequency determining interference thresholding is that in cumulative distribution function curve, functional value is the numerical value of 0.1.Which obtain adjacent frequency determining interference thresholding closer to actual conditions, the adjacent frequency determining interference thresholding adopting this obtain manner to obtain be used for screening higher as the base station accuracy in core interference base station.
3023, when the signal level of at least one the strongest adjacent cell corresponding to any one GSM network user and the difference of GSM adjacent frequency power leakage loss are more than or equal to adjacent frequency determining interference thresholding, OMC equipment determines that base station corresponding at least one the strongest adjacent cell is the base station in the set of core interference base station.
Be understandable that, each base station in the core interference base station set got is not the base station of causing interference for whether to the WCDMA signal in refarming-WCDMA network design district and obtaining, but determine by above-mentioned disturbed condition (signal level of at least one the strongest adjacent cell that any one GSM network user is corresponding and the difference of GSM adjacent frequency power leakage loss are more than or equal to adjacent frequency determining interference thresholding) base station that interference may be caused any one signal (WCDMA signal and/or GSM signal) in refarming-WCDMA network design district.Therefore interference may be caused to the WCDMA signal in refarming-WCDMA network design district in the base station of core interference base station set, or may can not cause interference to the WCDMA signal in refarming-WCDMA network design district.So after being obtained interference frequency point sets by step 301 and step 302 obtains the set of core interference base station, again by step 303, the base station of the frequency deploying interference frequency point sets is found, as the base station in target BS set from the set of core interference base station.
Further, in step 304, as shown in Figure 6, OMC equipment is determined to replace frequency point sets, comprising:
3041, OMC equipment determines the same adjacent frequency interference frequency point sets base station in target BS set being caused to co-channel interference and adjacent frequency interference.
Wherein, comprise with adjacent frequency interference frequency point sets the frequency each base station in target BS set being caused to co-channel interference and adjacent frequency interference.Therefore, the same frequency adjacent frequency that step 3041 is determined disturbs the scope of frequency point sets to be greater than the scope of the interference frequency point sets (FI) that step 301 is determined.If when being FK with the frequency point sets of adjacent frequency interference frequently, then
Optionally, before step 3041, OMC equipment can judge whether the set of core interference base station is empty set, when the set of core interference base station is nonvoid set, continues to perform step 3041.

Concrete, OMC equipment judges whether each frequency of replacing in frequency point sets causes interference successively, then obtains from displacement frequency point sets and does not cause the frequency of interference as the first displacement frequency to the WCDMA signal in refarming-WCDMA network design district.Wherein, the first displacement frequency number is identical with interference frequency (the interference frequency that namely in target BS set, each target BS the is corresponding) number needing to replace.
3052, when replacing all frequencies in frequency point sets and traveling through, OMC equipment obtains at least one the second displacement frequency WCDMA signal in refarming-WCDMA network design district being caused to least interference from displacement frequency point sets, and OMC equipment adopts at least one second displacement frequency to replace interference frequency corresponding to each target BS in target BS set.

New displacement frequency is the frequency GSM signal be in refarming-WCDMA network design district and buffering area not being caused to interference.
Because OMC equipment has carried out frequency replacement operator, original GSM frequency is planned upset, although Fig. 3, each step in Fig. 5-Fig. 8 evades problem GSM signal being caused to the interference of same adjacent frequency frequently, but still may occur that the first displacement frequency and/or the second displacement frequency cause the problem with adjacent frequency interference frequently to the GSM signal be in refarming-WCDMA network design district and buffering area, so OMC equipment needs to carry out interference simulation to new frequency programme, calculate the interference matrix between whole community, obtain disturbing weights, thus judge for replace first displacement frequency and/or second displacement frequency whether interference is caused to the GSM signal be in refarming-WCDMA network design district and buffering area.
It should be noted that, in the accompanying drawing of at least two kinds in Fig. 8 and Fig. 5, Fig. 6 and Fig. 7, combine the planing method that can form another frequency.
