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 (in the example of Fig. 4,10:00-12:00,13:00-15:00 and 15:30-17:30 are tri-kinds) 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 within every 5 minutes, storing the connection number of calls.Therefore the form that, the connection number of calls in time period k is a plurality of ordered series of numbers.For example, in the situation that the connection number of calls being stored in to network administration apparatus by every 5 minutes, the connection number of calls of time period 10:00-12:00 can show with 24 ordered series of numbers that connect the number 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 p in certain base station 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 reading in processing (9-1), and the average connection number of calls of obtaining corresponding to the moon, date, time period is stored in and is take on the number of calls table 6 that the date is classification.By carrying out in " p=[1～m month] between repeat " above-mentioned (9-1) and processing (9-2) (9-3), till before the past 1～m in d day, the time period k in a certain base station month, obtain respectively the average connection number of calls and be listed as.
Then, network administration apparatus 250, 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 ", is obtained " m monthly average " in d day, the time period k in certain base station.In addition, network administration apparatus 250 was stored in obtained a m monthly average to take in the number of calls table 6 that the date is classification corresponding to date, time period.Network administration apparatus is by the processing (9-5) at " between d=1～31 and k=" guardian's assigned operation time etc. " repeat " above-mentioned (9-1)～(9-4), obtains " m the monthly average " in certain base station through all time periods on whole dates.Further, network administration apparatus 250 is by the processing (9-6) to " plan subject base-station is implemented " above-mentioned (9-1)～(9-5), to planned subject base-station obtain all time periods on whole dates " m monthly average ".
Then, Fig. 6 the integration of the statistical disposition result based on number of weeks and date " process " (6-3) in, by to each base station with number of samples to Fig. 8 take " n week is average " of storage in the number of calls table 5 that number of weeks is classification and " m the monthly average " of storing in the number of calls table 6 that the date is classification of take of Figure 10 is weighted to carry out integration (asking weighted average), quantize take that date, number of weeks, time period be classification on the impact of user's communication service (below be designated as degree of impact).Concrete, the following formula of network administration apparatus 250 use is obtained degree of impact.
Degree of impact={ (n * [n week is average])+(m * [m monthly average]) }/(n+m)
For example, degree of impact is obtained respectively to each inputted date of operation, each time period in each base station.In addition, network administration apparatus 250, corresponding to date, number of weeks, time period, is stored in obtained degree of impact in service impact degree table 7.In addition, number of weeks can be according to the band date, and the suitable date in or beyond reference unit obtains.
For example, software upgrading plan is in the situation of " 10:00-12:00 Monday on the 2nd ", first according to Fig. 8, due to Monday, 10:00-12:00 " n week is average " is " 1.5 ", according to Figure 10,10:00 on the 2nd " m monthly average " is " 3 ", so the impact on user's communication service of " 10:00-12:00 Monday on the 2nd " is obtained as (1.5n+3m)/(n+m).Network administration apparatus 250 starts 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 degree table 7.Service impact degree table 7 has been stored and take the degree of impact on user's communication service that time period on date of each base station is classification.In the situation of Figure 11, on user's communication service affect minimum in base station number 1, be 9/2 (number of weeks one) 10:00-12:00 (degree of impact 1.6), be 9/2 (number of weeks one) 13:00-15:00 (degree of impact 9.4) in base station number 2.
In addition, in " integration of the statistical disposition result based on number of weeks and date is processed " 6-3, also can be as shown in following formula, by respectively number of weeks and date are applied to predetermined weighting a and b (obtaining weighted average), quantize paid attention to number of weeks and date one of them take the impact on user's communication service that date and number of weeks time period be 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 key diagram 3.In wireless communication networks 10, the region that base station 110 covers is most overlapping with adjacent base station.Therefore,, even if certain base station 110 stops business, also exist several in the terminal 300 that provides communication service by this base station 110 can continue by adjacent base station the situation of communication service.Therefore, if software upgrading adjacent base station when different can reduce the interruption of communication service.In software upgrading, implement in base station and date selection of time processing 3-3, take that what in the analyzing and processing 3-2 of statistical information, obtain is basis on the degree of impact of user's communication service and predetermined adjacent base station information, base station, date, number of weeks and the time period of selecting to implement software upgrading.
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 " base station number ", " the communication service degree of impact on user ", " adjacent base station number ", " software upgrading is predetermined ", " tentative/to determine ".
In Figure 12, first network administration apparatus 250 is selected the planned subject base-station of selecting in picture for " plan subject base-station " at Fig. 4, carries out " fixing tentatively " processing 12-1 on the number of weeks time period on date of degree of the impact minimum of user's communication service.During this is processed, network administration apparatus 250, with reference to the service impact degree table 7 shown in Figure 11, is selected the number of weeks time period on date on degree of the impact minimum of user's communication service in each base station.Network administration apparatus 250 arranges the selected number of weeks time period on date in adjustment form 8 in plan and is used as " software upgrading is predetermined ".In addition, " the communication service degree of affecting on user " of selected date number of weeks in the time period is set, and on " tentative/to determine " hurdle, " fixing tentatively " is set.
Then, for the base station A of certain plan object, implement to judge whether to exist for the adjacent base station of base station A, 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 for example, adjacent base station number corresponding to the base station number (base station number 2) as judgement object (for example 1,3,7,8...).In addition, network administration apparatus 250 is respectively for obtained adjacent base station number, and the base station number of adjustment form 8 is planned in retrieval, and obtains corresponding to the software upgrading of this base station number predetermined.Whether network administration apparatus 250 judgements for example, for example, repeat as the software upgrading predetermined (9/2 (one) 13:00-15:00) and the obtained software upgrading predetermined time section that judge the base station number (base station number 2) of object.
In the example of Figure 13, because the software upgrading of base station number 1 is predetermined and do not repeat as the software upgrading predetermined time section of the base station number 2,3,4,6,7 of its adjacent base station, so be judged as " not existing " in processing 12-2.In addition, for base station number 2, the software upgrading of base station number 2 is predetermined and repeat as the software upgrading predetermined time section of the base station number 7 of its adjacent base station, in processing 12-2, is judged as " existence ".In the situation that " do not exist " in the processing of 12-2, adopt the number of weeks time period on date of " fixing tentatively ", for base station A, the processing 12-5, concrete that implements to establish the number of weeks time period on date of " fix tentatively " works " decision ", general " fixes tentatively/decision " hurdle and changes into " decision " from " fixing tentatively ".In addition, in the situation that be judged as " existence " in the processing of (12-2), network administration apparatus 250 is carried out in base station A and B the relatively processing 12-3 on the degree of impact of user's communication service.
In processing 12-3, suppose to make the base station that degree of impact is little preferentially to carry out number of weeks time period option date, the number of weeks time period on date of further selecting degree of impact large is haveed no alternative but in the base station that degree of impact is large.Thus, imagination is according to the large situation of deviation of the different degree of impact in base station.In order to prevent this situation, suppress the deviation of the degree of impact of each base station, after processing in can make the base station that degree of impact is large preferentially carry out number of weeks option date.
In processing 12-3, in the situation that base station A degree of impact is large, adopt the number of weeks time period on date of " fixing tentatively ", for base station A, enforcement becomes the number of weeks time period on date of " fixing tentatively " in processing 12-1 the processing 12-5 of " decision ".On the other hand, in base station, B degree of impact is large, or in the equal situation of the degree of impact of base station A and base station B, from candidate, get rid of the number of weeks time period on date of the base station A of " fixing tentatively " in processing 12-1, for base station A, the processing 12-4 that the date number of weeks time period implementation modification of degree of the impact minimum of user's communication service " is fixed tentatively ", and again implement the processing of 12-2.
250 pairs of network administration apparatus plan subject base-station repeat to implement to process the processing 12-6 of 12-1～12-5, and " tentative/to determine " hurdle of Figure 13 is all set to " decisions ", thus 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 base station number 2 enforcement Figure 12.In Figure 13, base station number 7 is adjacent base stations of base station 2, and number of weeks time period time on software upgrading date of base station number 2 and base station number 7 is overlapping.In addition, base station 7 is large on the degree of impact of user's communication service.That is, in the judgement of processing 12-2, be equivalent to " existence ", and be equivalent to process 12-3 " base station B is large ".At this moment, by the processing of 12-4-2, from candidate, get rid of the number of weeks time period on software upgrading date arranging at base station number 2, the processing 12-4 that comes implementation modification " to fix tentatively ".According to the service impact degree table 7 of the base station number 2 of Figure 11, owing to having got rid of 9/2 (one) 10:00-12:00 having selected, so the number of weeks time period on software upgrading date of base station number 2 can be revised to " fixing tentatively ", be " 9/1 (day) 13:00-15:00 ".
In addition, foregoing description do not allow to carry out the situation of software upgrading with adjacent base station simultaneously, but also can be allowed until the repetition at adjacent base station N station.At this moment, can come corresponding by processing 12-2 being changed into the processing of " 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 N station ".
In addition, in above-mentioned processing, as an example, described and selected the wireless base station of degree of impact minimum, but also can select the wireless base station below predetermined threshold value except minimum.Further, in the situation that overlap with pre-settled date of software upgrading and the time period of adjacent base station, for a base station, except reselecting degree of impact inferior little operation day and time period, also can reselect degree of impact is other operation day and the time period below above-mentioned threshold value, also can reselect predetermined Second Threshold (for example, the value larger than above-mentioned threshold value) following operation day and time period.
The present invention can use in the relevant industry of the wireless communication system for example with a plurality of base station apparatus.
