In the statistical disposition 6-2 based on the date, network administration apparatus 250 implements to read the processing 9-1 of " the connection number of calls of d day, the time period k before the p in certain base station month ".Here, p can be 1 to m value, and d can be 1 to 31 value, and k can be the operating time section (10:00-12:00,13:00-15:00 and 15:30-17:30 are three kinds in the example of Fig. 4) of guardian's appointment.The statistical information of the connection number of calls of network administration apparatus 250 storage is regularly collected by certain some cycles as mentioned above, for example by storing the connection number of calls in per 5 minutes.Therefore, the connection number of calls among the time period k is the form of a plurality of ordered series of numbers.For example, will connect by per 5 minutes under the situation that the number of calls is stored in network administration apparatus, the connection number of calls of time period 10:00-12:00 can show with 24 ordered series of numbers that connect the numbers of calls.The processing (9-2) of network administration apparatus 250 by ensuing " obtaining the average connection number of calls of the time per unit of d day, the time period k before in certain base station p month according to (1) " is implemented in the on average processing of these ordered series of numbers of time per unit (hour or minute).For example, obtain number average of the connection of in handling (9-1), reading, and will to be stored in the date corresponding to the average connection number of calls that the moon, date, time period are obtained be on the number of calls table 6 of classification.By carrying out, till before the past 1～m among d day, the time period k in a certain base station month, obtain the average connection number of calls respectively and be listed as in " p=[1～m month] between repeat " above-mentioned (9-1) and processing (9-2) (9-3).
Then, network administration apparatus 250 is obtained " m monthly average " among d day, the time period k in certain base station by the processing 9-4 of " obtaining average (being called " m monthly average ") of the average connection number of calls of the time per unit of 1～m month d day, time period k separately ".In addition, corresponding to date, time period m the monthly average of being obtained to be stored in the date be in the number of calls table 6 of classification to network administration apparatus 250.Network administration apparatus is by the processing (9-5) at " repeating between d=1～31 and k=" guardian's assigned operation time etc. " " above-mentioned (9-1)～(9-4), and all time periods on whole dates of process are obtained " m the monthly average " in certain base station.Further, network administration apparatus 250 is by the processing (9-6) to " the plan subject base-station is implemented " above-mentioned (9-1)～(9-5), come to planned subject base-station obtain all time periods on whole dates " m monthly average ".
Then, Fig. 6 " integration based on the statistical disposition result on number of weeks and date is handled " (6-3) in, by to each base station with number of samples come to Fig. 8 with the number of weeks be " n week is average " of storage in the number of calls table 5 of classification and Figure 10 be that " m the monthly average " of storing in the number of calls table 6 of classification is weighted and carries out integration (asking weighted average) with the date, quantizing with date, number of weeks, time period is the influence to the user's communications business (below be designated as degree of influence) of classification.Concrete, the following formula of network administration apparatus 250 usefulness is obtained degree of influence.
Degree of influence={ (n * [n week is average])+(m * [m monthly average]) }/(n+m)
For example, each base station is obtained degree of influence respectively to each date of operation, each time period of being imported.In addition, network administration apparatus 250 was stored in the degree of being obtained of influence in the service impact kilsyth basalt 7 corresponding to date, number of weeks, time period.In addition, number of weeks can be according to the band date, in the reference unit or the outer suitable date obtain.
For example, the software upgrading plan is under the situation of " 10:00-12:00 Monday on the 2nd ", at first according to Fig. 8, because Monday, 10:00-12:00 " n week is average " was " 1.5 ", according to Figure 10,10:00 on the 2nd " m monthly average " is " 3 ", is (1.5n+3m)/(n+m) so the influence to the user's communications business of " 10:00-12:00 Monday on the 2nd " is obtained.Network administration apparatus 250 begins day to implement above-mentioned quantizing to the date and time section of expiration date for all software upgradings.
Figure 11 is the example of service impact kilsyth basalt 7.The time period on date that service impact kilsyth basalt 7 has been stored with each base station is the degree of influence to the user's communications business of classification.Under the situation of Figure 11, to the user's communications business influence minimum in basic station number 1, be 9/2 (number of weeks one) 10:00-12:00 (degree of influence 1.6), be 9/2 (number of weeks one) 13:00-15:00 (degree of influence 9.4) in basic station number 2.
In addition, in " integration based on the statistical disposition result on number of weeks and date is handled " 6-3, also can be shown in following formula, by respectively number of weeks and date are applied predetermined weighting a and b (obtaining weighted average), quantize paid attention to number of weeks and date one of them with date and number of weeks time period be the influence to the user's communications business of classification.
{ (a * n * [n week is average])+(b * m * [m monthly average]) }/(n+m)
Then, base station and date selection of time processing 3-3 are implemented in the software upgrading in the key diagram 3.In the wireless communication networks 10, the zone that base station 110 covers is most overlapping with adjacent base station.Therefore, even certain base station 110 stops business, also existing by this base station 110 provides several in the situation that can continue communication service by adjacent base station in the terminal 300 of communication service.Therefore, if software upgrading adjacent base station simultaneously not can reduce the interruption of communication service.Implement among base station and the date selection of time processing 3-3 in software upgrading, based on degree of influence and the predetermined adjacent base station information that in the analyzing and processing 3-2 of statistical information, obtains, base station, date, number of weeks and the time period of selecting to implement software upgrading to the user's communications business.
Figure 12 represents the concrete handling process of software upgrading enforcement base station and selection of time processing in period 3-3.Figure 13 represents to plan the structure example of adjustment form 8.Plan adjustment form 8 for example comprises " basic station number ", " to user's communications service impact degree ", " adjacent base station number ", " software upgrading is predetermined ", " tentative/decision ".
Among Figure 12, at first network administration apparatus 250 is carried out " fixing tentatively " processing 12-1 to the number of weeks time period on date of degree of the influence minimum of user's communications business for the planned subject base-station of selecting in Fig. 4 " plan subject base-station " to select in the picture.During this was handled, network administration apparatus 250 was selected the number of weeks time period on date to degree of the influence minimum of user's communications business with reference to service impact kilsyth basalt 7 shown in Figure 11 in each base station.Network administration apparatus 250 is provided with the selected number of weeks time period on date on the adjustment form 8 in plan and is used as " software upgrading is predetermined ".In addition, " to the user's communications service impact degree " of selected date number of weeks in the time period is set, and on " tentative/decision " hurdle, " fixing tentatively " is set.
Then,, implement to judge whether to exist for the adjacent base station of base station A for the base station A of certain plan object, and the processing 12-2 of the base station B of the number of weeks time period on date of " fixing tentatively " coincidence.For example, network administration apparatus 250 reference plan adjustment forms 8 obtain corresponding to as the adjacent base station of the basic station number (for example basic station number 2) of judging object number (for example 1,3,7,8...).In addition, network administration apparatus 250 is respectively for obtained adjacent base station number, the basic station number of retrieval plan adjustment form 8, and obtain corresponding to the software upgrading of this base station number predetermined.Network administration apparatus 250 judges whether software upgrading predetermined (for example 9/2 (one) 13:00-15:00) and the obtained software upgrading preset time section as the basic station number (for example basic station number 2) of judging object repeats.
In the example of Figure 13, because the software upgrading of basic station number 1 is predetermined and do not repeat as the software upgrading preset time section of the basic station number 2,3,4,6,7 of its adjacent base station, so in handling 12-2, be judged as " not existing ".In addition, for basic station number 2, the software upgrading of basic station number 2 is predetermined and repeat as the software upgrading preset time section of the basic station number 7 of its adjacent base station, is judged as " existence " in handling 12-2.Under the situation about in the processing of 12-2, " not existing ", adopt the number of weeks time period on date of " fixing tentatively ", for base station A, implement to establish the number of weeks time period on date of " fix tentatively " the processing 12-5, concrete of works " decision ", the general " fixes tentatively/determine " hurdle and changes into " decision " from " fixing tentatively ".In addition, be judged as in the processing of (12-2) under the situation of " existence ", network administration apparatus 250 is carried out in base station A and B relatively the processing 12-3 to the degree of influence of user's communications business.
In handling 12-3, suppose to make the little base station of degree of influence preferentially to come number of weeks time period option date, then number of weeks time period on date of further selecting degree of influence big is haveed no alternative but in the base station that degree of influence is big.Thus, imagination is according to the big situation of deviation of the different degree of influence in base station.In order to prevent this situation, suppress the deviation of the degree of influence of each base station, after processing in can make the big base station of degree of influence preferentially come number of weeks option date.
In handling 12-3, under the big situation of base station A influence degree, adopt the number of weeks time period on date of " fixing tentatively ", for base station A, enforcement will be in processing 12-1 the number of weeks time period on date of " fixing tentatively " become the processing 12-5 of " decision ".On the other hand, B degree of influence is big in the base station, or under the degree of influence of base station A and the base station B situation about equating, the number of weeks time period on date of from the candidate, getting rid of the base station A of " fixing tentatively " in handling 12-1, for base station A, the processing 12-4 that the date number of weeks time period implementation modification of degree of the influence minimum of user's communications business " is fixed tentatively ", and implement the processing of 12-2 once more.
250 pairs of network administration apparatus plan subject base-station repeats to implement to handle the processing 12-6 of 12-1～12-5, and " tentative/decision " hurdle of Figure 13 all is set to " decision ", thus the pre-settled date of software upgrading and the time period of definite planned subject base-station.
Table 8 when Figure 13 represents for the processing 12-3 of basic station number 2 enforcement Figure 12.The adjacent base station that basic station number 7 is base stations 2 among Figure 13, and number of weeks time period time on software upgrading date of basic station number 2 and basic station number 7 is overlapping.In addition, the degree of influence of the 7 pairs of user's communications business in base station is big.That is, in the judgement of handling 12-2, be equivalent to " existence ", and be equivalent to handle 12-3 " base station B is big ".At this moment, from the candidate, get rid of the number of weeks time period on software upgrading date that is provided with at basic station number 2, the processing 12-4 that comes implementation modification " to fix tentatively " by the processing of 12-4-2.According to the service impact kilsyth basalt 7 of the basic station number 2 of Figure 11,, be " 9/1 (day) 13:00-15:00 " so the number of weeks time period on software upgrading date of basic station number 2 can be revised " fixing tentatively " owing to got rid of 9/2 (one) 10:00-12:00 that has selected.
In addition, foregoing description do not allow to carry out simultaneously the situation of software upgrading with adjacent base station, but also can be allowed repetition up to adjacent base station N station.At this moment, the processing that can change into " judgement is whether the adjacent base station of base station A and the base station of number of weeks time period on date coincidence are more than the N station " by handling 12-2 comes corresponding.
In addition, in above-mentioned processing,, described and selected the wireless base station of degree of influence minimum, but except that minimum, also can select the following wireless base station of predetermined threshold value as an example.Further, under situation about overlapping with pre-settled date of the software upgrading of adjacent base station and time period, for a base station, except reselecting degree of influence inferior little operation day and time period, also can reselect degree of influence is following other operation day and time period of above-mentioned threshold value, also can reselect the second predetermined threshold value (for example, bigger value) following operation day and time period than above-mentioned threshold value.
