Embodiment three
With reference to Fig. 3, show the flow chart of steps of a kind of network coverage evaluation method according to the embodiment of the present invention three.
In the present embodiment, setting second generation communication network cell is GSM community, referred to as 2G cell; Setting third generation communication network cell is TD community, referred to as 3G community.
The network coverage evaluation method of the present embodiment comprises the following steps:
Step S302: obtain the G3(third generation communication network of signaling monitoring system) user is at the call bill data of IU interface+Iub interface and MR(measurement report) data, obtain the G3 user of signaling monitoring system in A interface+Abis interface call bill data and MR data.
Wherein, obtain the call bill data of G3 user at IU interface+Iub interface and the step of MR data of signaling monitoring system, and the G3 user obtaining signaling monitoring system can regardless of execution sequencing in the step of A interface+Abis interface call bill data and MR data.The traffic data of G3 user in third generation communication network cell and MR data can be known at the call bill data of IU interface+Iub interface and MR data by G3 user; The traffic data of G3 user in second generation communication network cell and MR data can be known at A interface+Abis interface call bill data and MR data by G3 user.
Signaling monitoring system (GSM and TD entirely supervises and entirely adopt) automatically can gather and get IU interface, Iub interface, A interface, the call bill data of Abis interface and the MR information of 2/3G.The present embodiment does based on the above-mentioned signaling data of signaling monitoring system collection the covering analyzing dividing flow analysis, 2G/3G refluence critical regions in 2G/3G community.
Wherein, the call bill data of acquisition comprises following ticket field:
| Field | Explanation |
| Network formats | Network formats is divided into 2G and 3G network |
| Time | The time that business occurs |
| IMSI | User profile |
| IMEI | End message |
| LAC | The lane place numbering that business occurs |
| CI | The cell number that business occurs |
| The duration of call | The duration of call that business occurs |
By above-mentioned ticket field, the information such as corresponding traffic duration, telephone traffic can be obtained.And by MR data, then can position analysis and coverage evaluating.
Step S304: obtain the 2G cell group that G3 user flows backwards serious based on mass tickets data.
The call bill data of the 2G/3G community obtained in integrating step S302, sorts from high to low to refluence telephone traffic, the 2G cell group that screening refluence telephone traffic is serious more than the refluence of Derl.Wherein, D value is generally got moon refluence telephone traffic and is greater than 200erl, and D value can adjust according to on-site actual situations.
Step S306: extract the 2G cell that the stream that flows backwards is serious.
Also namely, extract the serious 2G cell of stream that flows backwards in the 2G cell group obtained in step S304 and carry out follow-up judgement.
Step S308: judge whether there is TD community in the 2G cell H rice that current refluence is serious, if so, then performs step S312; If not, then step S310 is performed.
Wherein, H is the scope of setting, and H can value be generally 300 meters.
Step S310: if do not have TD community in the serious 2G cell H rice of current refluence, then otherwise export " not having TD website to need to carry out TD web construction outside H rice " suggestion, process ends.
Step S312: if the 2G cell H rice Nei You TD community that current refluence is serious, then carry out coverage evaluating in the serious 2G cell H rice region of current refluence, and whether weak covering causes G3 user to flow back to 2G cell to investigation serves.
Particularly, comprising:
Step S3122: the MR information utilizing 2G/3G community, is played up at map enterprising jargon business grid by 2G cell and 3G cell localization algorithm.
After meeting the serious 2G cell H rice Nei You TD community of current refluence, analyze the MR information of G3 user in 2G/3G community.Utilize the signal strength signal intensity of MR information, TA(Timing Advance), AOA(arrival direction angle) etc. information accurately locate, play up at map enterprising jargon business grid.
Wherein, 2G cell is multiple geographic area according to setting regular partition, corresponding to the multiple grids on map.In the present embodiment, grid size divides with 50*50, and grid comprises telephone traffic that G3 user produces respectively at GSM and TD network, flows backwards and compare size.Wherein, the ratio=G3 user of flowing backwards flows back to the telephone traffic of GSM community/(telephone traffic+G3 user that G3 user flows back to GSM community flows back to the telephone traffic of TD community).
Step S3124: the signal strength signal intensity MR information utilizing TD, carries out grid coverage evaluating in current region by 3G location algorithm.
Comprise: coverage evaluating is carried out to all traffic grids in current 2G cell.During assessment, carry out the assessment of TD network coverage grid according to TD location algorithm.Such as, if current grid TD signal strength signal intensity be less than-90dBm and sampled point accounting more than 20%, be then defined as weak covering grid.
Step S3126: judge whether current grid is high refluence grid, if so, then carries out step S3128; Otherwise, carry out step S314.
In the present embodiment, if the telephone traffic that the G3 user of current grid flows backward to 2G cell is greater than M, and refluence is then high refluence grid than being greater than N.Wherein, M, N value can carry out value according to actual conditions.As, moon refluence telephone traffic is greater than 200erl and flows backwards than being greater than 30%, be then high refluence grid.
Step S3128: judge whether current high refluence grid belongs to the weak covering grid of TD, if so, then carries out step S31210; Otherwise, enter step S314.
Step S31210: in the territory, height refluence grid occupied area judging weak covering in current region, whether high refluence grid sum ratio is greater than K, if so, then performs step S31214; Otherwise, perform step S31212.
This step judges whether the serious 2G cell of current refluence is that weak covering reason causes, and if so, performs step S31214, and exporting current region needs to carry out degree of depth coverage optimization; Otherwise, perform step S31212, carry out lock network customer analysis and network parameter investigation.
Wherein, K value can value be 30%.
Step S31212: lock network customer analysis and network parameter investigation are carried out to current 2G region, process ends.
Step S31214: export and need the prompting current 2G region being carried out to degree of depth coverage optimization, carry out step S314.
So far, by above-mentioned steps S312, achieve because of the weak covering of TD network cause G3 user to flow back to assessment that 2G cell carries out serving and investigation.
Step S314: judge whether that also there is the serious 2G cell of refluence does not also carry out coverage evaluating, if so, then returns step S306; If not, then process ends.
The present embodiment carries out unbalanced network coverage assessment based on the traffic data of signaling monitoring system and MR data, no longer be limited to operator through subsystem data, can obtain 2G/3G call bill data by signaling acquisition system, and the most original user data of extraction is analyzed; Meanwhile, do not need cross-platformly just can obtain MR information; Further, according to the MR information obtained, play up in conjunction with 2G/3G location algorithm and traffic grid, weak coverage evaluating is carried out to height refluence grid, investigate out and cause the unbalanced region of 2G/3G traffic because the TD degree of depth covers deficiency.By the present embodiment, the system that achieves adopts whole-course automation, without the need to manual intervention, comprising: automatically gather related data, automatically coverage evaluating, automatically export optimum ideals; The no longer limited data through subsystem just can carry out 2/3G shunting, have expanded Data Source; Original MR information dominance is utilized to locate the unbalanced region of traffic and coverage evaluating, true service condition that is true and accurately reflection user; Statistical analysis manpower can be saved by full automatic collection evaluation scheme, promote network optimization efficiency, save network optimization cost, and network optimization is risen to a new high degree to exploration that is intelligent, automation direction development.
