Embodiment
Below in conjunction with Figure of description and embodiment the present invention is done further detailed description.
The present invention is mainly through extracting existing network real-time traffic statistics and business datum automatically; Set up traffic model; Filter out interference and satisfy regularization condition sub-district adjustment cell parameter, handoff parameter and interference punishment parameter are controlled the influence of area interference to network in real time; When the interference that monitors the sub-district weakens or eliminates, will recover the raw parameter setting through callback mechanism.
Fig. 1 shows the flow chart of a kind of real-time method of adjustment of interfered cell model based on traffic measurement of the present invention, and this method mainly may further comprise the steps:
Step S11: extract the real-time traffic statistics result of sub-district in the existing network, set up the interfered cell traffic model;
Extract the real-time traffic statistics result of sub-district in the setting-up time granularity, for example 1 hour granularity traffic measurement is set up the interfered cell traffic model.Comprise that in the real-time traffic statistics result sub-district is in each rank of carrier frequency number, assignment success rate immediately, cutting off rate, number of dropped calls and speech quality on each rank interference fringe; Assignment success rate immediately is meant the success rate of sub-district request channel.
Wherein, interference fringe is the levels that channel that BTS channel reports to BSC through RF RES IND message in idle condition receives uplink interference, and being divided into is five grades, and level range can be set through LMT.The every number that obtained the idle channel (TCHF, TCHH or SDCCH) that once is in each interference fringe at a distance from 5 seconds of system; In measuring period Mo; Divided by sampling number, obtain the average number that idle channel (TCHF, TCHH or SDCCH) in measuring period is in each grade of interference fringe with the accumulated value of each sampling number certificate of this cycle.The interference fringe grade is high more, and the interference that expression receives is big more.In general, if the situation that idle channel falls into interference fringe 4,5 occurs, just think to exist and disturb.From interference fringe two to five numerical value has appearred, the then basic following principle " numerical value of interference fringe two is influence index not, and the numerical value of interference fringe three does not influence conversation but influence index, and numerical value appears in interference fringe more than three, then be the serious disturbance problem " that is suitable for.Exist if from estate performance is measured, seen the numerical value that has greater than 0, then must consider the influence that this interference brings.
Step S12:, the setting threshold of the regularization condition of parameter in the interfered cell is set according to the interfered cell traffic model;
According to the interfered cell traffic model of being set up, the setting threshold of the regularization condition of parameter in the interfered cell is set.Regularization condition comprises 4 grades and 5 grades of interference fringe ratios, assignment success rate immediately, cutting off rate, number of dropped calls and 6 grades and 7 grades of speech quality ratios; Rule of thumb value is provided with the threshold value of rational regularization condition; Through real-time monitor interference sub-district; Set up the traffic model of interfered cell; Filtering out through set above-mentioned threshold value influences the problem cells that the user normally uses communication again in the interfered cell, so that problem cells is adjusted the speech quality that improves the sub-district accordingly, the control area interference is to the influence of network.
Wherein, involved parameter is as shown in table 1 in this execution mode:
Table 1
By finding out in the table 1, each parameter all has parameter adjustment scope separately, when in step S13, as required parameter being adjusted, according to the adjusting range of each parameter and/or transfer big or turn down.
Step S13: the setting threshold according to interfered cell traffic model and regularization condition filters out problem cells, and problem cells is carried out the adjustment and the readjustment of parameter.
Setting threshold according to each set among interfered cell traffic model and step S12 regularization condition filters out the problem cells that influences proper communication in the interfered cell, and problem cells is carried out the adjustment and the readjustment of parameter.The size of the setting threshold of each regularization condition is set according to actual conditions and needs by the user; Can certainly adjust; In this execution mode, the setting threshold of each regularization condition as shown in Figure 2, the setting threshold of 4 grades and 5 grades interference fringe ratio sums is 20%; The setting threshold that is the assignment success rate is that the setting threshold of the ratio sum of 80%, 6 grade and 7 grades quality is 4%.
Wherein, screening problem cells and to carry out the flow chart of concrete mode of parameter adjustment and readjustment as shown in Figure 2:
1. calculate 4 grades and 5 grades of interference fringe ratios in the setting-up time granularity, check said 4 grades with 5 grades of interference fringe ratio sums whether greater than setting threshold, if then open BQHOEN and 2. INTRACELLHOEN is closed afterwards the entering step; Then directly get into step 5. if not;
In addition; In order to get rid of because cell carrier frequencies distributes the problem brought, 1. get into by step step 2. before, need check also whether the carrier frequency that is in 4 grades and 5 grades interference fringes concentrates on some carrier frequency; Then directly 1. get into step 2. if not, if the carrier frequency distribution then in the detected cells by step.If be indivedual carrier frequency in the sub-district because the carrier frequency of the sub-district of serious interference (being that 4-5 level interference fringe ratio is greater than 20%) is concentrated; The interference of that explanation sub-district is the caused interference of sub-district internal unit problem probably; Not external disturbance, so just need investigate the sub-district internal unit.Check that the mode whether carrier frequency that is in 4 grades and 5 grades interference fringes concentrates on some carrier frequency is:
Check following more whether setting up, if then explanation concentrates on some carrier frequency, then explanation does not concentrate on some carrier frequency if not:
< 4 grades and 5 grades of interference fringe ratio sums are less than 20% carrier frequency number, promptly exist the number of the serious carrier frequency that disturbs to account for the sub-fraction of carrier frequency in the sub-district greater than 20% carrier frequency number for 4 grades and 5 grades of interference fringe ratio sums
The formula that calculates 4 grades and 5 grades interference fringe ratio sums is:
(4 grades of number of times of TCHF/H interference fringe+5 grades of number of times of TCHF/H interference fringe)/(1 grade of number of times of TCHF/H interference fringe+2 grades of number of times of TCHF/H interference fringe+3 grades of number of times of TCHF/H interference fringe+4 grades of number of times of TCHF/H interference fringe+5 grades of number of times of TCHF/H interference fringe).
2. whether check assignment success rate immediately less than setting threshold, if then get into step 4.; Check then that if not 3. cutting off rate whether greater than setting threshold, if then get into step 4., then gets into step if not;
Wherein, the formula of calculating cutting off rate is:
(Traffic Channel number of dropped calls/TCH calling takies number of success+TCH switching and takies number of success)
3. check that 5. ratio sum that speech quality is in 6 grades and 7 grades quality whether greater than setting threshold, then gets into step, if then get into step 4. if not;
Wherein, calculating the formula that speech quality is in the ratio sum of 6 grades and 7 grades quality is:
(on the full half rate/descending 6 grades of quality of reception number of times+full half rate on/descending 7 grades of quality of reception number of times)/(on the full half rate/descending 1 grade of quality of reception number of times+full half rate on/descending 2 grades of quality of reception number of times+full half rate on/descending 3 grades of quality of reception number of times+full half rate on/descending 4 grades of quality of reception number of times+full half rate on/descending 5 grades of quality of reception number of times+full half rate on/descending 6 grades of quality of reception number of times+full half rate on/descending 7 grades of quality of reception number of times).
In the quality evaluation of traditional G SM network voice, speech quality RxQual (BER) is divided into 8 grades according to grade classification, and from the 0-7 level, its corresponding relation is following:
0 grade: < 0.2% is excellent for the error rate
1 grade: the error rate [0.2%, 0.4%) good
2 grades: the error rate [0.4%, 0.8%) good
3 grades: the error rate [0.8%, 1.6%) in
4 grades: the error rate [1.6%, 3.2%) qualified
5 grades: the error rate [3.2%, 6.4%) qualified
6 grades: the error rate [6.4%, 12.8%) poor
7 grades: the error rate >=12.8% bad
Therefore, the error rate is low more, and speech quality is good more, adopt in this execution mode speech quality be in 6 grades with 7 grades ratio sum as your standard of judgement.
4. transfer big DLEDGETHRES, TIMEBQPUNISH and ULEDGETHRES, turn ULQUALIMIT, DATAQUAFLTLEN and SSBQPUNISH down; Transfer big RXMIN and CRO simultaneously, PT is set;
When transferring big or turning parameter down, the size of adjustment by the user as required and the adjustment step-length of parameter adjust, the value after the parameter adjustment is (adjusting range shown in the table 1) within the adjusting range of parameter.
In the analytic process of the sub-district of reality balance optimizing,, the user is divided into two big types to user behavior in the interference region:
(1) idle condition user
For such user, through adjustment " cell reselection offset (CRO) " and " district reselecting Penalty time (PT) ", it is resident to control the sub-district, make its as far as possible gravity treatment take other adjacent sub-district.Through the Automatic Optimal of RXMI N parameter, with other sub-districts of user equilibrium value.
(2) state of activation user
User under the state of activation is divided into three types of A/B/C::
Category-A: the nearer incoming level in user distance base station is also higher, and its user is in the higher level state all the time through the control of adjustment power switch, has improved the C/I value, promotes antijamming capability; Control of cell uplink power and descending power control switch are closed.Design parameter comprises that uplink power control allows (UPPCEN) and descending power control to allow (DPPCEN).
Category-B: user distance base station and adjacent base station intersection, transfer big " down link edge handoff threshold (DLEDGETHRES) " and up link edge handoff threshold (ULEDGETHRES), turn " promptly switching uplink quality thresholding (ULQUALIMIT) " down.Still can not reach C/I condition user switches to neighbor cell in relative higher level to make it; Guarantee to open the BQ handoff algorithms and allow (BQHOEN) to be set to the YES state,, need to find early, can transfer short and small district filter length, realize that the quick response quality of sub-district is switched for having quality problems in existing sub-district.Comprise parameter voice/data channel signal quality filter length (DATAQUAFLTLEN) and signaling channel signal quality filter length (SIGQUAFLTLEN).Change problem for fear of intra-cell occurring, the intra of the sub-district that needs to have problems is closed, and parameter is that intra-cell is changed permission (INTRACELLHOEN) and is set to NO;
For the user of switching away owing to balance parameters adjustment mode; Need to transfer big " switch penalty duration of poor quality (TIMEBQPUNISH) " and switching signal intensity of poor quality punishment (SSBQPUNISH), avoid switching to former sub-district as far as possible because disturbance switching success back is returned.
The C class: user distance more maybe might switch to the user of end S base station, because there is interference problem in the sub-district, possibly cause the sub-district to have the handoff failure problem.There is handoff failure for switching to Target cell, need punishes, avoid the user to switch to Target cell once more the Target cell level.Big through transferring " handoff failure cell signal strength punishment (FAILSIGSTRPUNISH) " realizes as above target.
Certainly when carrying out the adjustment of access parameter and handoff parameter; Carry out to whole interfered cell; And can not adjust to the user in the sub-district, the concrete parameter adjustment during adjustment still need be according to the adjustment mode in this step, i.e. adjustment shown in Fig. 2.
5. whether carried out adjustment before checking IOX,, then do not adjust parameter if not if the IOX that then recovers before the adjustment is provided with.Recovering IOX before the adjustment is provided with and is meant if the IOX of sub-district is provided with and carried out adjustment (step 4. in parameter adjustment) before; When the area interference situation weakens or eliminates; The sub-district that IOX adjustment record will be arranged, parameter progressively return to its initial condition and guarantee that network well moves.
The present invention is through visual; The adjustment interface can be to the parameter of adjustment, and parameter adjustment scope step-length etc. and adjustment sub-district switch are manually controlled adjustment; Be convenient to the user flexibility use and the good step-length of the different adjusting ranges of adjustment is set according to different districts; Can control the optimization effect that reaches better to sub-district adjustment switch in abnormal conditions, reduce the risk of dropped calls of network, improve user's in the interfered cell coverage speech quality.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technology thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
