WCDMA, as one of mainstream system of 3G, has developed into the comparatively ripe stage.Along with the rapid growth of data service, network load is increasing, and the Intranet interference problem under WCDMA standard becomes increasingly conspicuous, and wherein, the reasonability of network configuration has accounted for leading position in affecting the factor of network quality.Early stage the network planning unreasonable, caused the usefulness of a large amount of base stations of existing network low, had a strong impact on network quality and user awareness.
In the prior art, to the assessment of network configuration, being generally by analyzing MR(Measurement Report, measurement report) data, drive test data obtain that network is whole to be covered and disturbed condition; The corresponding network index such as the resource utilizations such as the network performance by traffic measurement data analysis base station, power, CE (Channel Element, channel resource), code word and each base station call amount.
But, carry out that drive test need to drop into a large amount of manpower and materials, repeatability is lower and contingency is strong; Network performance, telephone traffic and resource utilization difficulty associated with wireless environment is larger, and correlation is lower, cannot draw regular conclusion.
The present invention is according to existing network data, a kind of rational method of WCDMA wireless network architecture has been proposed, use existing network data to solve drive test data and be difficult to the problem obtaining, and, the invention provides a kind of evaluation criteria of quantification, for optimizing existing network and network planning construction afterwards, provide foundation accurately.
With the following Examples, describe a kind of rational method of WCDMA wireless network architecture that the present invention proposes in detail.
Embodiment mono-
A kind of rational method of WCDMA wireless network architecture that the embodiment of the present invention proposes, in conjunction with Fig. 1, the method specifically comprises:
101, obtain the traffic statistics data of all communities, comprise community voice telephone traffic amount, data traffic, channel quality indicator (CQI), radio resource control RRC successful connection number of times, between two inter-cell soft handoff number of times.
Described traffic statistics, data from existing network data, comprise community voice telephone traffic amount, data traffic, channel quality indicator (CQI), radio resource control RRC successful connection number of times, between two inter-cell soft handoff number of times and some other parameters.
For the collection of traffic statistics data, can gather by network management platform, can be to adopt other modes to gather, the present invention is not specifically limited this.
102, according to described community voice telephone traffic amount, data traffic, RRC successful connection number of times and CQI, calculate the efficiency of eating dishes without rice or wine of all communities.
The efficiency of eating dishes without rice or wine of community is the ratio of the maximum bearer traffic of traffic carrying capacity and community of the current carrying in community.
Wherein, according to RRC successful connection number of times, can estimate the signaling consumption of described community; Using described community, current voice telephone traffic amount, data traffic and signaling consumption is as the traffic carrying capacity of the current carrying in community.
Concrete, when calculating the traffic carrying capacity of the current carrying in described community, the signaling consumption of the voice telephone traffic amount of community, RRC successful connection can be converted be the data traffic that equal-wattage consumes, thereby estimates the traffic carrying capacity of the current carrying in community.
In embodiments of the present invention, can to voice telephone traffic amount, convert according to the result of reality test.For example, single speech business is dialed the voice telephone traffic amount producing for a hour and is equivalent to the power consumption that speed is 50Kbps download generation in a hour, therefore, can by cellular traffic conversion, be the data traffic A of equal-wattage according to following formula:
A=voice are number of users * 50kb/s* measurement period simultaneously
Wherein, voice simultaneously number of users can obtain by the anti-ERLANG B of looking into of the percent of call lost based on 2% according to circuit domain telephone traffic, get near value while running into non-integer.
Certainly, it is data traffic by the telephone traffic conversion in measurement period that the embodiment of the present invention also can adopt other modes, and the present invention is not specifically limited this.
Concrete, for measurement period, can be one hour, can be also other times length, the present invention is not specifically limited this.
By traffic statistics data, can directly obtain the data traffic in measurement period, owing to there will be the situation of data re-transmission in data transmission procedure, therefore having actual data traffic is data traffic and the product that retransmits coefficient in traffic statistics data, and this retransmits coefficient desirable 1.2 based on experience value.
In order to improve RRC connection, be created as power, reduce RRC connection set-up delay, promote customer service perception, most of RRC connection can be based upon DCH (Dedicated Channel, dedicated channel) on channel, DCH is mapped on DPCH (Dedicated Physical Channel--DPCH) channel, DPCH adopts OVSF (the Orthogonal Variable Spreading Factor of SF=128, Orthogonal Variable Spreading Factor OVSF) code carries out band spectrum modulation, just be equivalent to the data service of a 13.6kb/s, and RRC connects process of establishing needs the time delay of 2～4 seconds, therefore the data volume convert formula of signaling consumption is as follows:
Signaling consumption data volume=RRC number of success * 4s*13.6kb/s1)
The number of success connecting according to RRC in traffic statistics data, according to above-mentioned formula 1), can obtain the signaling consumption in measurement period.
Data flow value and the signaling consumption of the telephone traffic A that is data traffic according to conversion obtained above, reality, three's summation obtains the traffic carrying capacity of the current carrying in current area.
Further, the CQI reporting according to traffic statistics data small area, by the corresponding ultimate throughput table of inquiry CQI, can know the ultimate throughput of each community.
Consider user's use habit and traffic performance, when the maximum bearer traffic of calculation plot, introduce duty ratio, can know duty ratio according to actual test experience, for example 0.9.The ultimate throughput that CQI that community reports is corresponding and the product of duty ratio obtain the maximum bearer traffic of community.
The maximum bearer traffic of the current bearer traffic in community obtained above and community is done to the efficiency of eating dishes without rice or wine that ratio obtains community.
Certainly, to those skilled in the art, also can adopt other known technology of this area to know the efficiency of eating dishes without rice or wine of community, the embodiment of the present invention repeats no more this.
103, the size of the efficiency of eating dishes without rice or wine of described all communities is sorted, filter out in preset range Nei community as doubtful problem cells.
Wherein, described preset range can be not more than the first preset value and/or the efficiency sequence of eating dishes without rice or wine is not less than the scope of the second preset value for the efficiency sequence of eating dishes without rice or wine, and described the second preset value is greater than described the first preset value.
Such as, You100Ge community in network, sorts to whole communities according to each community descending order of efficiency of eating dishes without rice or wine, if get front 5%(, comprises 5%) comprise 5% with rear 5%() community as doubtful problem cells, the first preset value is that 5, the second preset values are 95.
Consider network carriers equipping rules, after the size of the efficiency of eating dishes without rice or wine of described all communities is sorted, for different network carriers equipping ruless, different default scopes is set and screens doubtful problem cells.
Concrete, if the whole network carrier wave is configured to business layered model, as the speech business of F1 carriers carry and R99 business, F2 and other carriers carry HSPA business, classified according to corresponding carrying in all communities, according to different carrier wave configurations, select to eat dishes without rice or wine in the community of the whole network voice-bearer and R99 business most effective 5% community and the minimum 5% of the efficiency community of eating dishes without rice or wine, select the whole network only to carry to eat dishes without rice or wine in the community of HSPA business the higher 5% of efficiency community and eat dishes without rice or wine the lower 5% of efficiency community as doubtful problem cells.
If the whole network carrier wave is configured to load sharing, the higher 10% of the efficiency community and eat dishes without rice or wine the lower 10% of efficiency community as doubtful problem cells of selecting to eat dishes without rice or wine in the whole network community.
Certainly, for the sequence of the efficiency of eating dishes without rice or wine, can be to sort from big to small, can be also to sort from small to large, the embodiment of the present invention is not specifically limited.
