Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 1, the embodiment of the invention determines that the method for co-frequency cell comprises the following steps:
Wherein, be statistic with probable value frequently according to the interference difference of a period of time, if statistic add up to A, add up to B greater than the statistics of interference threshold, B/A promptly characterizes with probable value frequently so.
Interference threshold value and probability threshold value can be set and upgrade as required; Also can determine by network actual conditions or emulation.
Wherein, each sub-district all has a frequency at least.The first uplink interference value and the second uplink interference value that can determine at the ascending time slot of each frequency.
At a frequency, in the step 101, it is poor that the first uplink interference value of this frequency correspondence of synchronization and the second uplink interference value are done, and the numerical value that obtains is as the uplink interference difference of this frequency correspondence; Wherein, the first uplink interference value is the uplink interference of other sub-districts to Target cell; The second uplink interference value be in the Neighboring Cell List of Target cell signal strength signal intensity greater than the interference of the sub-district of signal threshold value to Target cell.
But the uplink interference difference is represented not join the co-frequency cell in the Neighboring Cell List of Target cell and is joined in the Neighboring Cell List of Target cell do not bring into because co-channel interference is more weak with frequently uniting sub-district in the joint-detection to the interference level of Target cell.
The uplink interference value here can be ISCP (Interference Signal Code Power, a slot interfering signal of time sign indicating number power) value, also can be that other can represent the parameter value that disturbs.
If the uplink interference value can be ISCP, then the first uplink interference value can obtain by high-rise; It is poor also the RSCP (Received Signal Code Power received signal code power) of the RTWP of Target cell (Received Total Wideband Power receives the broadband gross power) and Target cell can be done, and obtains the first uplink interference value.
In the step 101,, determine to set all uplink interference differences of this frequency correspondence in the duration at a frequency; Accordingly, in the step 102, determine in the uplink interference difference of this frequency correspondence quantity greater than the uplink interference difference of interference threshold value; According to determine greater than the quantity of the uplink interference difference of interference threshold value and set the total quantity of the uplink interference difference of determining in the duration, determine the same frequency probable value of this frequency.
Concrete, set in the duration and add up, analyze accumulated probability and distribute, if take place the uplink interference difference greater than the same frequency probable value of interference threshold value greater than the interference threshold value, determining then that Target cell has leaks the adjacent area of joining.
Setting duration can adjust as required; Also can determine by network actual conditions or emulation.
In the step 101, in setting duration, can determine all uplink interference differences of frequency correspondence the cycle; Also can determine all uplink interference differences of frequency correspondence constantly.
In the step 103, there is multiple mode can determine the sub-district, enumerates several below.
Mode one, according to the coverage direction of Target cell, determine frequency and not sub-district in the Neighboring Cell List of Target cell identical with the frequency that finds.
Preferable, can preferentially choose adjacent with Target cell or relative sub-district with the coverage direction of Target cell.
Concrete, in the coverage direction of Target cell, search and the sub-district of uplink interference value greater than the identical frequency of the frequency of threshold value; From the sub-district of finding, extract the not sub-district in the Neighboring Cell List of Target cell.
Mode two, definite not in the Neighboring Cell List of Target cell in the adjacent area of Target cell, and the frequency that existence is identical with Target cell, and this frequency in leaking allocating cell corresponding uplink interference difference greater than the same frequency probable value of interference threshold value sub-district greater than the probability threshold value.
Concrete, after definite Target cell has miss-configured neighboring cells, check around the Target cell sub-district that meets above-mentioned condition is also arranged, whether promptly check has the uplink interference of frequency correspondence difference greater than the same frequency probable value of the interference threshold value sub-district greater than the probability threshold value, if have, and the frequency of this frequency and Target cell is identical, and this sub-district is then selected in this sub-district not in the Neighboring Cell List of Target cell.
Preferable, check when around the Target cell sub-district that meets above-mentioned condition being arranged also, can watch the sub-district that is in the Target cell first lap by position planning information in the ground of network, watch then and be in Target cell second circle, and the like.
Need to prove that the embodiment of the invention is not limited to above-mentioned dual mode, other can determine that frequency and mode not sub-district in the Neighboring Cell List of Target cell identical with the frequency that finds all is suitable for the embodiment of the invention.
In the step 104, the sub-district of finding is added in the Neighboring Cell List of Target cell.Preferable, Target cell can also be added in the Neighboring Cell List of the sub-district of finding.
In whole network, can carry out above-mentioned steps as Target cell successively in each sub-district.Preferable, can discharge the sub-district of non-co-channel interference earlier, will remain the sub-district successively as Target cell.
Accordingly, can further include before the step 101:
To exist the sub-district of co-channel interference in the network successively as Target cell.
Concrete, will exist the sub-district of co-channel interference in the network as a set; From set, select a sub-district successively as Target cell.
In force, can be by obtaining the interference level value of all sub-districts under the whole network, the evaluating objects sub-district be subjected to disturbed condition, cause the interference phenomenon difference can get rid of the situation of some common non-co-channel interferences according to different situations.Enumerate the situation of several common non-co-channel interferences below.
1, GPS (Global Positioning Systems, global positioning system) sideslip: be divided into two kinds of situations, a kind of is that signal shifts to an earlier date, at this moment, self is interfered Target cell, and the sub-district around him does not have usually, if signal lag, have a slice sub-district so and be interfered, but Target cell itself does not have.
2, the far-end of base station disturbs: certain zone is subjected to serious interference, if Target cell is positioned at this panel region, the location far-end disturbs so earlier, if do not have, relocates co-channel interference so.
3, external disturbance: all frequencies, the time slot of sub-district all are subjected to strong jamming, find interference source earlier, check again after solving whether the sub-district also has interference again.
Need to prove that the situation of non-co-channel interference just illustrates in above-mentioned 3, the situation of non-co-channel interference has much and can not enumerate one by one, and other can determine it is that the situation of non-co-channel interference is suitable for the embodiment of the invention equally.
Though the sub-district of determining is added in the Neighboring Cell List of Target cell, might leak more than one of the sub-district of configuration, preferable, step 104 can further include afterwards:
Determine the corresponding uplink interference difference of frequency of the Target cell identical with the frequency of the sub-district of adding Neighboring Cell List to; If the uplink interference difference of determining is then returned step 103 greater than the same frequency probable value of the interference threshold value frequency greater than the probability threshold value.
Concrete, because after in the Neighboring Cell List that the sub-district of determining is added to Target cell, Target cell can adopt with frequently detecting interference cancellation techniques, reduce influence, so the uplink interference value of the Target cell that the frequency that Target cell is identical with initiate sub-district is corresponding should reduce, if only leak sub-district of configuration, set the interior uplink interference difference of duration and return the frequency that is not more than the probability threshold value greater than the same frequency probable value of interference threshold value; If also have to leak the sub-district of configuration,, promptly return step 103 so need to continue to determine frequency and the sub-district in the Neighboring Cell List of Target cell not identical with the frequency that finds greater than explanation.
Wherein, the embodiment of the invention determines that the executive agent of the method for co-frequency cell can be base station, RNC (Radio Network Controller, radio network controller), network optimization instrument etc.

In step 202, the judgement set whether the sub-district is arranged,, from set, select a sub-district as Target cell if having, and execution in step 203; Otherwise, process ends.
Step 203, determine the uplink interference difference of each frequency correspondence of Target cell.
Step 204, judge whether to have in all uplink interference differences and set uplink interference difference in the duration that if having, then execution in step 205 greater than the same frequency probable value of interference threshold value frequency greater than the probability threshold value; Otherwise, and return step 202 with Target cell deletion from set.
Whether step 205, judgement have in the adjacent area of Target cell not in the Neighboring Cell List of Target cell, and the frequency that existence is identical with Target cell, and this frequency in leaking allocating cell corresponding uplink interference difference greater than the same frequency probable value of interference threshold value leakage allocating cell greater than the probability threshold value, if have, then execution in step 206; Otherwise, and return step 202 with Target cell deletion from set.
Step 206, add in the Neighboring Cell List of Target cell, and Target cell is added in the Neighboring Cell List that leaks allocating cell leaking the allocating cell sub-district.
Step 207, determine the corresponding uplink interference difference of frequency of the Target cell identical, judge that the uplink interference difference is whether greater than the same frequency probable value of the interference threshold value frequency greater than the probability threshold value, if then return step 205 with the frequency of leakage allocating cell; Otherwise, and return step 202 with Target cell deletion from set.
