For problems of the prior art, the embodiment of the invention provides corresponding solution, in order to realize the automatic generation of neighbor cell between different system, shortens generating period, promotes the accuracy that generates the result.Below in conjunction with Figure of description the solution that the embodiment of the invention provides is elaborated.
The embodiment of the invention proposes: realize the generation of neighbor cell between different system based on the base station geographical conditions.As shown in Figure 1, the generation method of neighbor cell comprises the steps: between different system
S101, according to the stop spacing between the base station cell different system cell adjacent with each and different system cell that each is adjacent and the relative position of base station cell, choose alternative different system neighbor cell;
S102, according to the deflection of the stop spacing between alternative different system neighbor cell and the base station cell and alternative different system neighbor cell and base station cell, determine respectively the weight of each alternative different system neighbor cell;
S103, choose different system neighbor cell according to the weight of each alternative different system neighbor cell, generate the different system neighbor cell list of base station cell.
Specific implementation process to each step is elaborated.
In the implementation of S101, before choosing alternative different system neighbor cell, at first define several Selecting All Parameters:
Preset the first distance threshold D1, the general span of the first distance threshold D1 is 10m～20m, also can set flexibly according to base station actual deployment situation;
Determine between different system cell that each is adjacent and the base station cell greater than the minimum station of this first distance threshold D1 apart from and long-pending for generating the adjacent area distance apart from weights K set; Even the residential quarter value with cover type is not different for the different mobile communication system apart from weights K, for example for GSM residential quarter and the continuous coverage cell of TD-SCDMA, be 1.5 apart from the general value of weights K, for TD-SCDMA edges cover residential quarter, be 3 apart from the general value of weights K, also can be according to also can base station actual deployment situation setting flexibly apart from the value of weights K;
Preset maximum adjacent area distance, the maximum adjacent area general span of distance is 2km～3km, also can set flexibly according to base station actual deployment situation;
Determine that generation adjacent area distance and maximum adjacent area are second distance threshold value D2 apart from the smaller value among both, obviously second distance threshold value D2 is greater than the first distance threshold D1;
Determine the adjacent section planning zone of base station cell, the adjacent section planning zone refers to the definite sector region of angle of coverage set by second distance threshold value D2 and for base station cell.If base station cell is omnidirectional macro base station residential quarter or home base station cells, the angle of coverage of then setting for base station cell is 360 degree; If base station cell is directed macro base station residential quarter, the angle of coverage of then setting for base station cell spends greater than 0 and less than 180 degree, the adjacent section planning area schematic of directed macro base station residential quarter sees also Fig. 2.
Based on the Selecting All Parameters of definition, can determine whether certain different system cell of base station cell is alternative different system neighbor cell, concrete:

For macro base station, three directional antennas of a general configuration, each directional antenna has a deflection, normally 0 degree, 120 degree and 240 degree.Generally take direct north as 0 degree reference direction, and deflection increases along clockwise direction; For the macro base station that disposes three directional antennas, usually form three base station cells, the deflection of each base station cell is the deflection of corresponding directional antenna.For stop spacing line angle, also be take direct north as 0 degree reference direction, namely be wired to the angle of direct north under base station cell and the alternative different system neighbor cell between the base station.
Further, stop spacing between base station cell and adjacent different system cell is greater than the first distance threshold D1 and less than second distance threshold value D2, and when the adjacent section planning zone of different system cell and base station cell is not overlapping, if base station cell is directed macro base station residential quarter, different system cell is the macro base station residential quarter, the semicircle zone overlaid (namely with the zone 2 shown in Fig. 2 or regional 3 overlaids) at the place, adjacent section planning zone of this different system cell and base station cell, and the adjacent section planning of base station cell and different system cell zone overlaid, determine that then this different system cell is alternative different system neighbor cell, wherein the adjacent section planning zone of different system cell refers to by second distance threshold value D2 and is the definite sector region of angle of coverage that different system cell is set.
The below illustrates and judges whether certain adjacent different system cell of base station cell is the method for alternative different system neighbor cell, suppose that base station cell is TD-SCDMA residential quarter (3G residential quarter), then its Home System is the TD-SCDMA system, different system is gsm system, and corresponding different system cell is GSM residential quarter (2G cell).Suppose that the first distance threshold D1 and second distance threshold value D2 are definite, judge then whether certain adjacent GSM residential quarter, TD-SCDMA residential quarter is the method for alternative different system neighbor cell, as shown in Figure 3, comprises the steps:

Perhaps, Angle1=360-fabs (AngleAB-AngleA)
Angle2 calculates by following formula:
Angle2＝fabs(AngleBA-AngleB)
Perhaps, Angle2=360-fabs (AngleBA-AngleB)
Wherein, fabs () expression takes absolute value, AngleAB and AngleBA all represent stop spacing line angle, the deflection of line between the base station under base station cell and the alternative different system neighbor cell namely, both essence is identical, just the consideration based on the line direction has provided respectively AngleAB and AngleBA, AngleAB is the deflection of base station base station line under the alternative different system neighbor cell under the base station cell specifically, and AngleBA is the deflection of base station base station line under the base station cell under the alternative different system neighbor cell specifically; AngleA represents the deflection of base station cell, and AngleB represents the deflection of alternative different system neighbor cell.
It should be noted that, Angle1 is the angle between the deflection of AngleAB and base station cell, Angle2 is the angle between the deflection of AngleBA and alternative different system neighbor cell, and so-called angle all is no more than 180 degree, so Angle1 and Angle2 provide respectively two computing formula.
C, determine that stop spacing and angular transition between alternative different system neighbor cell and the base station cell are the weight of alternative different system neighbor cell apart from sum, represent by following formula:
Weight＝DistanceAB+D
angle＝DistanceAB+T×(Angle1+Angle2)
Wherein, Weight represents the weight of alternative different system neighbor cell, D
AngleExpression angular transition distance, DistanceAB represents the stop spacing between alternative different system neighbor cell and the base station cell, namely the air line distance between the base station under the alternative different system affiliated base station of neighbor cell and the base station cell.

A, according to each the alternative different system neighbor cell ordering to determining of the ascending order of weight;
B, from each alternative different system neighbor cell that ordering is finished, choose set quantity at front alternative different system neighbor cell as different system neighbor cell, generate the different system neighbor cell list of base station cell, wherein, different system neighbor cell list comprises the configuration information of each different system neighbor cell;
In the implementation, setting the general value of quantity is 32; Different system neighbor cell list not only comprises the configuration information of each different system neighbor cell, also needs to comprise the essential information of base station cell.
If base station cell is the TD-SCDMA residential quarter, different system neighbor cell is the GSM residential quarter, then the concrete form of different system neighbor cell list is as shown in table 1, and the essential information of base station cell comprises: RNC ID (radio network controller identifier), CI (cell ID), base station property; The configuration information of different system neighbor cell comprises: CI, LAC (Location Area Code), NCC (Network Color Code), BCC (BCC), BCCH (Broadcasting Control Channel, Broadcast Control Channel) frequency, BAND (network frequency range) and base station property.Wherein, BAND indication network frequency range is GSM900 or DSC1800, and the base station property indication is macro base station or Home eNodeB.Table 1 is WCDMA residential quarter or CDMA2000 residential quarter for base station cell, and is same applicable; Be the situation of CDMA residential quarter for different system neighbor cell, only need that BCCH frequency option is replaced with the scrambling code information option and get final product.

The different system neighbor cell list of base stations detected residential quarter, when the different system neighbor cell that exists with BCCH frequency and same BSIC (base station identity code), the different system neighbor cell that weight is larger is deleted from different system neighbor cell list;
BSIC is comprised of NCC and BCC, and the value of NCC and BCC is 0-7, and NCC is used for recognition network, and BCC is used for distinguishing the GSM residential quarter of using identical BCCH frequency.If two GSM residential quarters are with BCCH frequency and same BSIC, therefore the wrong identification that then can cause Target cell in the interference of wave point and the cell switch process can not exist the different system neighbor cell with BCCH frequency and same BSIC (base station identity code) in the different system neighbor cell list.
Need to prove that the different system neighbor cell list of TD-SCDMA residential quarter can for the GSM900 in the gsm system and the separately planning of two network frequency ranges of DSC1800, also can merge planning.
If base station cell is the GSM residential quarter, different system neighbor cell is the TD-SCDMA residential quarter, then the concrete form of different system neighbor cell list is as shown in table 2, and the essential information of base station cell comprises: CI, LAC, NCC, BCC, BCCH frequency, BAND and base station property; The configuration information of different system neighbor cell comprises: RNC ID, CI, frequency point information, scrambling code information and base station property.Table 2 is WCDMA residential quarter or CDMA2000 residential quarter for different system neighbor cell, and is same applicable; Be the situation of CDMA residential quarter for base station cell, only need that BCCH frequency option is replaced with the scrambling code information option and get final product.
Table 2
In the implementation, set the alternative different system neighbor cell outside front alternative different system neighbor cell of quantity in the alternative different system of each that ordering can also the be finished neighbor cell as the different system of candidate neighbor cell, generate the different system of the candidate neighbor cell list of base station cell, the concrete form of the different system of candidate neighbor cell list is consistent with the concrete form of different system neighbor cell list, comprises equally the essential information of base station cell, the configuration information of the different system of each candidate neighbor cell.
Because the cover type of base station comprises continuous covering and edges cover, base station property comprises macro base station and Home eNodeB, provides in light of the circumstances following some explanation:
For 3G macro base station residential quarter, if the base station covers continuously and is intensive, then 3G network can be realized continuous covering, in this case, 3G network and 2G network all have good covering, so the 3G residential quarter need not to dispose too much 2G system neighbor cell, then disposing with covering and ground floor neighbor cell mutually with 2G macro base station residential quarter is different system neighbor cell.On the contrary, edge at the 3G cell coverage area, in order to guarantee that cell reselection, switching etc. normally carry out, need the relatively many 2G system neighbor cells of configuration, be different system neighbor cell with the mutually same covering of configuration of 2G macro base station residential quarter, ground floor and second layer neighbor cell then.Ground floor refers to the 2G base station that NodeB is adjacent, and the second layer refers to NodeB time adjacent 2G base station, middle also 2G base station, interval, and then distance is relatively far away.For whether the edge of base station range can be judged according to the 3G signal strength signal intensity.
For 2G, 3G home base station cells altogether, 2G, 3G are configured to mutually neighbor cell between the home base station cells altogether, and with macro base station cell configuration ground floor neighbor cell be different system neighbor cell.
For the 2G home base station cells, with 3G macro base station cell configuration ground floor neighbor cell be different system neighbor cell.
For the 3G home base station cells, with 2G macro base station cell configuration ground floor neighbor cell be different system neighbor cell.
