In the present embodiment, list information in particular cell also can farther include restriction optimization list information, isolation list information；Restriction optimizes each community comprised in list information and does not allow to delete or increase, and the adjacent area of the Target cell in isolation list information is only the community specified in region；

Now in above-mentioned optimization process, before switching cell is labeled as deletion, also includes judging whether this switching cell optimizes in list information in restriction, as no, then this switching cell is labeled as deletion；

In above-mentioned optimization process, before switching cell is configured to the newly-increased adjacent area of Target cell, also include judging whether this switching cell optimizes in list information in restriction, as no, judge that switching cell is whether in the appointment region of described Target cell further according to isolation list information, in this way, in the Neighboring Relation Table of Target cell, this switching cell is configured to the newly-increased adjacent area of this Target cell.

In order to be better understood from the present invention, illustrative for a kind of concrete particular cell list information below, refer to shown in table one:

Obtain the primary importance information of the base station of Target cell and the second position information of the base station of switching cell；Specifically can pass through to obtain the engineering parameter data of network in above-mentioned steps 101, from the engineering parameter data acquisition obtained to the positional information of each base station；

Whether the distance judging between the base station of Target cell and the base station of this switching cell according to the primary importance information obtained and second position information is less than super neighbour district distance threshold, in this way, show that the two is super close distance adjacent area, this switching cell can not be deleted, as no, just described switching cell is labeled as deletion.

In the present embodiment, before being optimized process based on the adjacent area in the cell handover information the obtained Neighboring Relation Table to Target cell, in order to promote efficiency and the accuracy of follow-up optimization, in advance the interference data in cell handover information and hash can being filtered operation, this filters operation and specifically comprises the steps that

Switching times virtual in cell handover information is deleted less than the record of certain soft-handoff threshold less than the record of certain virtual switching threshold and the soft handover number of times of non-neighboring BS relationship, in order to remove interference data or hash.It is verified.Additionally, in the present embodiment before calling particular cell list information, also the community list in this particular cell list information can be verified, prevent each list in this particular cell list information from colliding with each other, after verifying entry/exit conflicts, it is possible to delete the community list of conflict or only delete one of them in two conflict districts.

In above-mentioned steps 103, the adjacent area optimized in Neighboring Relation Table carries out interworking correcting process obtain the first correction Neighboring Relation Table and be: the adjacent area (it should be understood that being for all adjacent areas) newly increased optimized in Neighboring Relation Table is carried out interworking correcting process, and interworking correcting process follows following principle:

A: the adjacent area for main plot, with Target cell for described main plot with the adjacent area that respectively newly increases respectively；

B: if using the Target cell adjacent area as main plot, when the adjacent area number of this main plot is more than predetermined number threshold value, then be judged to can not interworking, this main plot is deleted from optimizing Neighboring Relation Table；

C: if Target cell is in the Neighboring Relation Table of main plot, and main plot is not labeled as deletion when optimization process, it is determined that for completing interworking；

D: if Target cell is in the Neighboring Relation Table of main plot, and when optimization process, main plot is labeled as deletion, then cancel and optimize the deletion labelling of this main plot in Neighboring Relation Table；

E: if Target cell has had been configured as the newly-increased adjacent area of main plot in the optimization process of main plot, it is determined that for completing interworking；

Also can farther include:

F: if Target cell needs to increase the interworking adjacent area of other adjacent areas, community several, but its adjacent area number that can increase is less than this number, then take bigger several of switching times and accompany adjacent area as the adjacent area of this Target cell mutually when increasing.

It should be appreciated that mentioned above principle all can carry out, according to concrete application scenarios, the adjustment that adapts to.

In the present embodiment, the Neighboring Relation Table of all communities all can obtain from the radio configuration data of network, and specifically can obtain in above-mentioned steps 101；The configuration data and the engineering parameter data that obtain in the present embodiment are all the data after latest update, to ensure that in configuration data and engineering parameter, simultaneous field has same value.

In above-mentioned steps 104, first adjacent area revised in list carries out scrambler multiplexing correction obtain the second correction Neighboring Relation Table and be: revise, to first, the adjacent area (it should be understood that being for all adjacent areas) newly increased in list and carry out scrambler multiplexing correction, including:

Revise list is deleted first and cause the neighboring BS relationship that scrambler multiplexed path number is maximum, then the path, adjacent area recalculating remaining newly-increased neighboring BS relationship place causes scrambler multiplexed path number, and deletion causes the neighboring BS relationship that scrambler multiplexed path number is maximum in the first correction list, until newly-increased neighboring BS relationship will not cause scrambler multiplexing, obtain the second correction Neighboring Relation Table.Illustrate with a concrete example below, with A-B represents that newly-increased adjacent area illustrates, and refers to shown in table two:

Table two

Above table causes scrambler multiplexed path number maximum for A-> B, delete this neighboring BS relationship of A-> B, then recalculate, until newly-increased neighboring BS relationship will not cause scrambler multiplexing, obtain the second correction Neighboring Relation Table.
