Fig. 3 shows the further structure of comprehensive diagnos analysis module (16), and it comprises:
Grouping module (161), a covering problem zone and layer calling problem area that three message-analysis module (14) obtain that physical layer parametric analysis module (13) is obtained divide into groups.Illustrate below in conjunction with specific embodiment:
Suppose the somewhere has been carried out drive test and call testing simultaneously, from drive test data, judge the zone that has covering problem and have 1., 2., 3., 4., 5., be expressed as I{ 1., 2., 3., 4., 5. }; Judge from the call testing data and exist the zone of calling problem to have: 1., 2., 6., 7., 8., be expressed as II{ 1., 2., 6., 7., 8. }, grouping module (161) is grouped into table 1 with the fault that each problem area exists:
Table 1
| I | II | ||
| ① | A little less than the covering | ① | Access failure |
| ② | Pilot pollution | ② | |
| ③ | Up covering is limited | ⑥ | |
| ④ | Disturb | ⑦ | Call drop |
| ⑤ | A little less than the covering | ⑧ | Communication quality is poor |
Judge module (162), judge whether to exist and cover and call out the problem area that is associated, if there is no cover and call out the problem area that is associated, then judge it is covering problem zone or calling problem area, if covering problem zone, analyzing and diagnosing covering problem zone then, and structure covering problem cell set, if calling problem area, then analyzing and diagnosing is called out problem area, and structure calling problem cells collection, covers and call out the problem area that is associated if exist, then analyzing and diagnosing covers and calls out the related question zone, and constructs covering and call out the related question cell set.Associative list 1 concrete judgement is as follows:
By table 1 as seen, set of regions I and set of regions II exist and occur simultaneously, and this point can be seen more obviously in Fig. 9.1. the area I of Fig. 9 comprise, 2., and 3., 4., 5., 1. area I I comprise, 2., and 6., 7., 8., can set up incidence relation, that is to say exist to cover and call out the problem area that is associated promptly 1., 2., as the common factor of mid portion among Fig. 9, so just can construct covering problem set of regions α 3., 4., 5. }, call out problem area collection β { 6., 7., 8. }, cover and call out related question set of regions γ 1., 2..
At covering and calling out the related question zone 1., there are weak and two problems of access failure of covering, therefore can judge tentatively that zone access failure 1. is weak relevant with its covering, further analyze in conjunction with relevant signaling process and physical layer parameter again, get rid of other problems such as switching, power control, traffic congestion, can judge that then zone access failure 1. causes a little less than covering.In like manner, can judge also that at covering and call out the related question zone 2., similarly analyzing zone call drop 2. is owing to pilot pollution causes.
Suppose to cause the problem cells of each regional fault as shown in table 2 by analyzing to locate:
Table 2
| The zone | Problem cells | The zone | Problem cells |
| ① | a、b | ② | b、c、d、e |
| ③ | f、g | ⑥ | g、h |
| ④ | f、h、i | ⑦ | h、i |
| ⑤ | g、h、i | ⑧ | h、i、j |
Then can construct and cover and calling related question cell set C{a b, c, d, e}, covering problem cell set A{f, g, h, i}, calling problem cells collection B{g, h, i, j}.
Constructing the module (163) of unified problem cells collection, is object with the problem cells, and failure cause is carried out sort merge, and constructs unified problem cells collection.
Still be example with top embodiment.With problem cells a, b, c, d, e, f, g, h, i, j is object, fault is carried out sort merge, can construct a little less than unified problem cells collection: the a{ covering, access failure }, a little less than b{ covers, access failure, pilot pollution, call drop }, the c{ pilot pollution, the d{ pilot pollution, the e{ pilot pollution, the up covering of f{ is limited, disturb }, the up covering of g{ is limited, cover weak }, h{ disturbs, a little less than the covering, insert overtime, call drop, communication quality is poor }, i{ disturbs, a little less than the covering, call drop, communication quality is poor }, the j{ communication quality is poor.
The module (164) of the optimizing cells group that structure can independently be adjusted is carried out sort merge to problem cells, and constructs the optimizing cells group that can independently adjust.For example, it also is example with the foregoing description, suppose that the independent problem cells a that adjusts only can affect to problem cells b, the independent problem cells b that adjusts also only can affect to problem cells a, and to other problem sub-district c, d...j can not impact, and then problem cells a and b can be configured to the optimizing cells group that can independently adjust, be expressed as optimizing cells group 1{a, b}.
Relating module (165) associates the network characterization parameter configuration in the fault of each optimizing cells group and the network characterization storehouse, carries out association analysis, and whether failure judgement is relevant with the network characterization parameter configuration.Still can realize about this part, for example, by programming which type of network characterization parameter configuration can be set and be associated with which type of fault by the mode of programming.This relating module is according to fault then, and as " covering weak " in the present embodiment, judging whether can be this fault and network characterization configuration association.
Optimize suggestion module (166), if fault is associated with the network characterization parameter configuration, that is to say, fault can be thought to be caused by the network characterization parameter configuration, then provide network configuration optimization suggestion, this mode of suggestion of giving also can realize by the mode of programming, as programming for how adjusting the network characterization parameter configuration at certain fault, can accomplish to those skilled in the art, if it is uncorrelated, fault is considered to may be relevant with cell configuration, then provides cell configuration optimization suggestion.
