May be provided in the center of community, with the conglobate area of coverage of omnidirectional antenna shape, here it is " center-driven " mode.Also base station can be set
On hexagonal three summits, each community, each base station uses the beam antenna of three secondary 120 degree of fan beams, is covered each by
The region of each 1/3rd of three neighbor cells, each community is collectively covered by three secondary 120 degree of fan anteenas, here it is " top
Point excitation " mode, and the region that every slave antenna covers is exactly a base station section, a base station section is also referred to as a community.
One base station can also be divided into six sectors or nine sectors, is referred to as " six sectors " solution or " nine
Sector " solution.Wherein, " nine sectors " solution uses space multiplexing technique and Huawei's unique algorithm, by grinding voluntarily
The three wave beam high-gain splitting antennas sent out, in the horizontal direction by the sector that the sector splitting of 120 degree is three 40 degree, i.e.

Solution is disposed and is gradually raised the curtain.Continuous Innovation, power-assisted operator are promoted network capacity by following many sectors solution,
Meet following ever-increasing number of users and data traffic requirement.
In mobile communication system, in order to improve frequency efficiency, increase the capacity of system, usually use channeling skill
Art.Channeling refers to after separated by a distance, in given overlay area, there is the same class frequency of many uses
Community, these communities are referred to as co-frequency cell.Interference between co-frequency cell is referred to as co-channel interference.
The technology of general employing channeling is to increase spectrum efficiency.Base station service area is made constantly to contract when community constantly divides
Little, when increasing with frequency multiplexing coefficient, substantial amounts of co-channel interference will replace man-made noise and other disturbs, and become the master to Small Section Mode
Retrain.At this moment mobile radio environment will be become interference-limited environment from noise-limited environment.
In embodiments of the present invention, when terminal needs to switch over community, it is thus necessary to determine that switch to which homogeneous-frequency adjacent-domain,
Then need homogeneous-frequency adjacent-domain is carried out signal quality testing.In the embodiment that some are feasible, when base station finds that terminal needs switching
During community, a common frequency measurement can be issued and control signaling, in this common frequency measurement signaling, carry multiple homogeneous-frequency adjacent-domains of this community, with
Make terminal that multiple common frequency measurement adjacent areas of this community are carried out signal quality testing, to select signal quality preferably adjacent with frequency
District switches over.
But, the inner regulation of agreement 331 is in order to ensure the normal switching of terminal, the most permissible inside common frequency measurement control
Carry 31 adjacent areas and all carry out sending measuring.But if common frequency measurement control is excessive, can easily cause Signaling Radio Bearer
(English: Signalling Radio Bearer；Abbreviation: the SRB) call drop resetted, simultaneously also due to consume the too much time
Issue, the time delay that traffic affecting is set up.
According to data statistics, Philippine Globe office point: the statistical result of 6 RNC, the homogeneous-frequency adjacent-domain number of 38% exceedes
30；Thailand AIS office point: the adjacent area number of 50% is more than 31；VHA office point, Australia: the adjacent area number of 14% more than 31, the neighbour of 58%
District's number is between 20-30.
Along with the development of many sectors, the community number of introducing increases, and the number ratio more than 31 in homogeneous-frequency adjacent-domain increases, community
Between pilot pollution, soft handover area increase, it is not necessary to soft handover increase, cause cutting off rate to raise.
The embodiment of the present invention is by proposing the homogeneous-frequency adjacent-domain by configuring community, after obtaining homogeneous-frequency adjacent-domain set, permissible
Determine the important homogeneous-frequency adjacent-domain in the set of this homogeneous-frequency adjacent-domain, obtain the set of important homogeneous-frequency adjacent-domain, when the terminal this community being detected
When switching to new community, common frequency measurement can be sent to this terminal and control signaling, without manual operation, but by wireless network
Network controller is automatically obtained, and embodies intellectuality and convenience.
For ease of understanding, being described the idiographic flow in the embodiment of the present invention below, refer to Fig. 2, the present invention is real
Execute a kind of one embodiment of data processing method in example to include:
201, configure the homogeneous-frequency adjacent-domain of community, obtain the homogeneous-frequency adjacent-domain set of this community.
In embodiments of the present invention, RNC can whether homogeneous-frequency adjacent-domain relation configures between community.Need explanation
It is that homogeneous-frequency adjacent-domain relation is typically all the far and near decision according to the geographical position between Liang Ge community, if Liang Ge community
Geographical position relatively, coverage has overlapping, typically will be configured to neighboring BS relationship, otherwise, do not configure.
In the embodiment that some are feasible, it is usually and can have cell-of-origin according to the signal measuring community of terminal to report
And the signal of relation of other communities, if the signal of some community is stronger, typically this community and cell-of-origin will be joined
It is set to homogeneous-frequency adjacent-domain relation.But, in the embodiment that other are feasible, if the wireless environment of surrounding changes, as
Newly-increased or delete a base station, or newly-built Liao Yidong building etc., homogeneous-frequency adjacent-domain relation is it is possible to occur some to change.But
If not having the improvement of these wireless environments, then homogeneous-frequency adjacent-domain relation typically would not send change.
Such as, if the interval between the community A1 of base station A and the community B1 of base station B is relatively, signal is stronger, then
Hui Jiang community A1 and community B1 is configured to neighboring BS relationship.Same, if the community A2 of the community A1 of base station A and base station A is also
Same principle, the different districts of the same frequency below a general base station all can be configured to neighboring BS relationship.When for
After all cell configuration relation of corresponding homogeneous-frequency adjacent-domain, each community has corresponding homogeneous-frequency adjacent-domain to gather.Need explanation
, a community does not has any one homogeneous-frequency adjacent-domain, i.e. this homogeneous-frequency adjacent-domain set can be empty set.
202, the switching related data of this community is obtained.
In the embodiment that some are feasible, owing to the community under a base station gets more and more, the homogeneous-frequency adjacent-domain of a community
Also getting more and more, when needs issue common frequency measurement control, substantial amounts of common frequency measurement controls all to carry 31 homogeneous-frequency adjacent-domains of the upper limit.
To this end, then need to reduce the homogeneous-frequency adjacent-domain that the probability wherein connected is less, leave important homogeneous-frequency adjacent-domain.Important with frequency in order to distinguish
Adjacent area and insignificant homogeneous-frequency adjacent-domain, then need the switching related data of community.
In the embodiment that some are feasible, terminal attempts switching over community every time, all can record, then timing or
Person's event is sent to RNC when triggering, and terminal can only send number of attempt and number of success, it is also possible to be calculated success rate it
Rear transmission, is not construed as limiting herein.Terminal can receive self terminal send to base station, then by base station send about community
Switching related data.In the embodiment that some are feasible, this switching related data includes switching number of attempt and handover success
Number of times, in the embodiment that other are feasible, it is also possible to include handover success rate, be not construed as limiting herein.
203, the significance level ranking of each homogeneous-frequency adjacent-domain in gathering according to this this homogeneous-frequency adjacent-domain of switching correlation data calculation,
Obtain homogeneous-frequency adjacent-domain significance level list.
In the embodiment that some are feasible, can be by the switching related data of number of success and number of attempt to frequency
Marking in homogeneous-frequency adjacent-domain in the set of adjacent area, carries out ranking according to scoring, obtain homogeneous-frequency adjacent-domain significance level list.
In the embodiment that some are feasible, different homogeneous-frequency adjacent-domains can be switched to by Statistic Source community in configuration
The switching number of attempt of handover success number of times and correspondence, is calculated with frequency by handover success number of times/switching number of attempt
Handover success rate.
In the embodiment that some are feasible, so that homogeneous-frequency adjacent-domain score value is equal to: handover success rate * handover success
Number.It is understood that handover success rate is the important references standard representing its significance level, but the most unique standard,
Because if the number of times of the scheme implemented is considerably less, such as 1 time, even if then success rate is 100%, can not be referred to as important
Homogeneous-frequency adjacent-domain.
In the embodiment that some are feasible, in order to preferably score value be compared, can be 0-100 by its score value naturalization
Between numerical value.Concrete grammar can be divided by the score value of the maximum homogeneous-frequency adjacent-domain of score value by the score value of each homogeneous-frequency adjacent-domain, then
It is multiplied by 100, obtains the numerical value between 0-100.It should be noted that if switching number of attempt is 0, direct switching part is got
It is divided into 0, handover success rate need not be calculated.
It should be noted that be to use network planning network optimization tool to obtain switching phase from RNC by staff under original technology
Close data, through collecting, analyze and calculate the mark of each homogeneous-frequency adjacent-domain, further according to the ranking carrying out significance level.And
In embodiments of the present invention, only rely on RNC automatically to use and collect, analyze and calculate switching related data and obtain drawing each with frequency
The mark of adjacent area, further according to the ranking carrying out significance level.
204, determine the number of homogeneous-frequency adjacent-domain in the set of this important homogeneous-frequency adjacent-domain according to this switching related data, obtain this heavy
Want homogeneous-frequency adjacent-domain number.
In the embodiment that some are feasible, after the significance level ranking obtaining different homogeneous-frequency adjacent-domains, can be taken it
In several homogeneous-frequency adjacent-domains as important homogeneous-frequency adjacent-domain.But, if only taking the homogeneous-frequency adjacent-domain of wherein fixed number as weight
Want homogeneous-frequency adjacent-domain, it is likely that produce some score value the lowest be also likely to be important homogeneous-frequency adjacent-domain, what score value was the highest is not weight
Want homogeneous-frequency adjacent-domain.So-called important homogeneous-frequency adjacent-domain, i.e. its number of times being switched are abundant, and success rate is sufficiently high simultaneously, to this end, this
Bright embodiment provides a kind of and may determine that the method for the number of homogeneous-frequency adjacent-domain in the set of its important homogeneous-frequency adjacent-domain.
Specifically, first arrange adjacent area ranking M that minimum homogeneous-frequency adjacent-domain number thresholding is corresponding.As, M could be arranged to 7
Individual or 8, it is not construed as limiting herein.According to minimum homogeneous-frequency adjacent-domain number thresholding, adjacent area according to handover success number of times sequence from
High to Low, take the homogeneous-frequency adjacent-domain of 1-M before ranking.
Then cumulative distribution function is obtained (English: Cumulative Distribution Function；Abbreviation: CDF)
Adjacent area ranking N that switching accounting thresholding is corresponding.CDF is the probability that stochastic variable is less than or equal to certain numerical value, and CDF switching herein accounts for
Ratio refers to that the soft handover number of success of community two-by-two of adjacent area ranking≤N accounts for the total soft handover in cell-of-origin and accumulates the ratio of successfully number.CDF cuts
Change the value way of adjacent area ranking N corresponding to accounting thresholding: first of ranking is added up in the adjacent area corresponding more than or equal to this thresholding.
Such as, if CDF switching accounting thresholding is set to 90%, then following form cell ID be 18431 switching corresponding to community account for
The homogeneous-frequency adjacent-domain of ranking 11 than 90% adjacent area, i.e. N=11.It should be noted that its CDF switching accounting thresholding can be according to need
