If receive the signal of same PN in some regions terminal simultaneously, can cause terminal to sector misjudgment, cause the problem of handoff failure and call drop. This just requires network configuration and optimization personnel reasonably to plan with PN and adjacent PN (can become same PN in space after certain propagation delay) network, to ensure good network performance. But communication network scale is that a very perfect PN planning is also difficult to meet the network dilatation demand of two to three years along with the network user's development dilatation gradually, therefore within taking two to three years, whole net is carried out to PN planning and amendment is extremely necessary as the cycle.

Detailed description of the invention
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, net the schematic flow sheet of an embodiment of PN amending method for the present invention is whole. In the present embodiment, whole net PN modification process comprises:
All sectors physical parameter separately in step 101, collection wireless communication networks, carries out the planning of PN according to the described physical parameter gathering to scene corresponding to each sector in described all sectors;
Step 102, each base station sub-system equipment from described cordless communication network obtain the Neighboring Cell List of all sectors, and the PN after each sector planning in described all sectors is substituted in the Neighboring Cell List of described all sectors;
Step 103, from the Neighboring Cell List of described all sectors, screen irrational PN and irrational neighboring BS relationship, and the irrational PN filtering out and irrational neighboring BS relationship are planned again;
Step 104, through again planning and screening, the PN eliminating after irrational PN and irrational neighboring BS relationship is substituted into the Neighboring Cell List of corresponding sector, and the parameter list of all sectors after planning is formed to configuration data library file;
Step 105, described configuration data library file is imported to the configuration database of described each base station sub-system described each base station sub-system equipment off line in the situation that, so that the configuration data of described each base station sub-system load format in online situation, the line activating of going forward side by side.
In the present embodiment, the collection of physical parameter can be obtained in conjunction with means such as site inspections by the engineering parameter summary table of attendant's regular maintenance, and physical parameter can comprise that sector longitude and latitude, azimuth, sector, antenna are hung high, covering scene and whether sector is districts and cities or inter-provincial border etc. Obtaining after physical parameter, can also set up sector engineering parameter database, to preserve and to arrange the physical parameter collecting.
In PN planning, can divide into groups to PN according to network requirement, for example carry out scene grouping according to indoor, outdoor and border, and according to geographical position and scene, PN planning is carried out in all sectors in the whole network. Concrete PN planning mode can adopt existing PN planning mode. For example, in the middle of planning, if consider that in same system, delay estimation is made mistakes, other pilot tone is likely by wrong demodulation, affect network quality, therefore need to ensure that different pilot tones have certain isolation, avoid occurring disturbing because pilot demodulated mistake produces between different districts.
From avoiding adjacent PN_Offset to disturb and disturbing two angles to consider phase difference (PILOT_INC with PN_Offset, corresponding 64 chips of each unit) arrange: avoid adjacent PN_Offset to disturb, the difference that requires the interval between adjacent PN_Offset to cause than propagation delay is much bigger; Avoid same PN_Offset to disturb, require difference that propagation delay causes to be greater than the half of pilot search window size. Consider the requirement of this two aspect, can draw the rational parameter setting of PILOT_INC.
After selected PILOT_INC, can adopt the mode that differs certain constant between three pilot tones of continuous setting or same base station to carry out PN planning. In addition, in the time that pilot tone is planned, need to retain a part of pilot resources as retaining collection, as later dilatation. For this reason, the initial stage, while planning, is twice PILOT_INC expansion pilot tone is set: reduce on the one hand initial stage network and produce because base station range causes more greatly transmission delay between pilot tone the possibility of disturbing; On the other hand for later stage dilatation reserves abundant PN resource.
For the PN after each sector planning is replaced in the Neighboring Cell List of each sector, in the Neighboring Cell List after replacement, also exist the multiplexing irrational problem of PN, these irrational PN and irrational neighboring BS relationship need to be screened out away. Wherein irrational PN mainly refers to that the geographical position multiplex distance of the sector with identical PN is less than default minimum multiplex distance, or the base station number with interval between the sector of identical PN is less than base station, default minimum interval number. The PN of respective sectors all belongs to irrational PN in this case.
Irrational neighboring BS relationship mainly comprises 1-WAY adjacent area and 2-WAY adjacent area, wherein Fig. 2 shows the schematic diagram of irrational 1-WAY neighboring BS relationship, 1-WAY adjacent area is that to have two sectors of identical PN all adjacent with the 3rd sector, in Fig. 2, sector A and sector B, sector C are adjacent area, and sector B has identical PN with sector C. Under this neighboring BS relationship, if mobile phone terminal, in sector A, while receiving the signal of sector B, because sector B is identical with the PN of sector C, causes system to judge accurately and selects to sector B or sector C switching, thereby cause handoff failure, cause call drop.
Fig. 3 shows the schematic diagram of irrational 2-WAY neighboring BS relationship. 2-WAY adjacent area is the adjacent area each other, adjacent area separately, two sectors with identical PN, and in Fig. 3, sector A and sector B, sector C are adjacent area, and sector B and sector D are adjacent area, and sector C has identical PN with sector D. If there is the 2-WAY adjacent area shown in Fig. 3, sector A and sector are present in Active Set simultaneously, system can be carried out adjacent area merging, namely sector C and sector D are integrated in adjacent area, if now mobile phone terminal has received the signal of sector C, system also can judge to sector C or sector D to be switched, and causes handoff failure, causes call drop.
For above-mentioned irrational PN, can again plan for these irrational PN, and not need all PN again to plan. For irrational neighboring BS relationship, also need to judge the switching times of the relevant adjacent area in this neighboring BS relationship, the switching times of each sector normally obtains in the process of Neighboring Cell List that gathers all sectors, switching times is relevant with the userbase situation in this sector to a certain extent, for the more sector of switching times, in order to reduce the impact on user, conventionally adopt the mode that the PN of relevant adjacent area is planned again; And for the less sector of switching times, because less on user's impact, therefore can directly in Neighboring Cell List, delete this irrational neighboring BS relationship.
Through above-mentioned planning again and screening process repeatedly, until eliminated irrational PN and irrational neighboring BS relationship, the parameter list (part that Neighboring Cell List is parameter list) of each sector after planning forms configuration data library file the most at last, and loads in each base station sub-system with this.
From the present embodiment, can find out, by the whole network PN planning, irrational PN and irrational neighboring BS relationship being screened and planning again, can effectively eliminate the problem easily occurring in PN planning, avoid the impact on network performance.
Revise from large-scale whole net PN, need to adopt than current dynamically input PN data the mode mode more efficiently to foreground, and the present embodiment has adopted the mode that off line imports and online loading activates, can realize the whole net PN amendment of faster time, the embodiment that detailed process is shown in Figure 4. The parameter list that figure 4 illustrates all sectors after planning forms configuration data library file, and configuration data library file is imported to the configuration database of described each base station sub-system described each base station sub-system equipment off line in the situation that, so that the configuration data of described each base station sub-system load format in online situation, the go forward side by side specific implementation process of line activating, comprising:
Step 201, taking the configuration data library file of described each base station sub-system as basis, the configuration data library file of described each base station sub-system is imported in self contained data base;
Step 202, according to the parameter list of all sectors after described planning, the pilot number of each sector in described self contained data base is replaced, formed new configuration data library file;
Step 203, close the base station controller in base station sub-system Operation & Maintenance System on-the-fly modify switch, described configuration data library file is imported to the background data base of described base station sub-system in the situation that of off line;
Step 204, open the switch that on-the-fly modifies of described Operation & Maintenance System, described configuration database is formatted as to the spendable data format of each main processing veneer in the base station controller in described base station sub-system online in the situation that;
Step 205, described each the main processing veneer that resets, be loaded into the data in described configuration database in described each main processing veneer and activate.
In the present embodiment, adopt the mode of vary off-line database, when loading, be loaded into foreground from database, load the time used very short, the business that affects is only in the time period of activating on equipment foreground, generally only need a few minutes or tens minutes, and existing PN alter mode need to take to utilize order to revise one by one the PN of each sector from backstage, the amendment of each sector needs to on-the-fly modify database and is loaded into foreground, and under this mode, if database update information is more, may cause revising all base stations under a base station controller need a few hours or and tens hours, operating period has a strong impact on user awareness, in addition, new PN when amendment may easily conflict with the PN of existing network configuration, causes the part sector cannot online modification, also can cause the processing time to extend, and is unfavorable for practical operation. can find out by contrast, the present invention can shorten the time of the whole network PN amendment greatly, and the operating time is also very short to user's service impact, also comparatively easy in operation.
For example, at cordless communication network (cdma network) through construction and optimization for many years, in the numerous situation of outdoor macro base station and indoor distribution number of sectors, PN in network adopts the early programme of time, and keep for the PN of newly-built station to be exhausted, and will face when large quantities of newly-built stations networks the situation that can use without PN.
