Only think the sub-district of 3G mobile communication system in the embodiments of the invention, as Wideband Code Division Multiple Access (WCDMA) (WCDMA) communication system, the network cell configuration of 2 G mobile communication system adjacent area of CDMA 2000 (CDMA2000) communication system or time division duplex-S-CDMA (TD-SCDMA) communication system and the description carried out, but the present invention is suitable for the situation of other mobile communication system coexistences except above-mentioned mobile communication system equally.
Be described further for the method and apparatus of 3G cell configuration 2G adjacent area of the present invention below in conjunction with accompanying drawing.
First embodiment
Fig. 1 be first embodiment of the invention be the method flow diagram of 3G cell configuration 2G adjacent area, as shown in Figure 1, comprise the steps:
In this step, current adjacent area collection, the alternative collection in adjacent area are set and wait to delete the adjacent area collection.The initial value of described current adjacent area collection is that initial time is the set of each 2G adjacent area of 3G cell configuration, it is the current 2G neighbor cell configuration collection of 3G sub-district correspondence, this set can be expressed as A={A1, A2 ... Am}, wherein, A1, A2,, Am is represented as each 2G adjacent area of current 3G cell configuration respectively.
The initial value of above-mentioned current 2G adjacent area collection can obtain by prior art, for example, artificially estimates configuration and the in-plant 2G cell in 3G sub-district according to the geographic distribution of 2G network; Perhaps, when NodeB and 2G base station colocation site, the 2G adjacent area of 3G sub-district is disposed in reference with the configuration of the 2G cell of site; Perhaps, dispose the 2G adjacent area of 3G sub-district with reference to the drive test data in network optimization process.
In the present embodiment, the alternative collection in adjacent area is the set of concentrating the 2G adjacent area composition of selecting from the configurable 2G adjacent area of 3G sub-district, and this set can be expressed as B={B1, B2,, Bn}, wherein, B1, B2 ..., Bn represents the configurable 2G adjacent area of current 3G sub-district correspondence respectively.Described each alternative 2G adjacent area can calculate distance in the address location of 3G sub-district therewith by each 2G cell geographical position, selects from the near to the remote, also can be according to the rule that sets in advance, might become in the sub-district of 2G adjacent area, 3G sub-district and select.Suppose, altogether corresponding 50 2G adjacent areas, current 3G sub-district, and 20 2G adjacent areas wherein have been configured to the 2G adjacent area of this 3G sub-district, and the 2G adjacent area that these are configured can be expressed as A1, A2 ..., A20; Then the alternative 2G adjacent area of current 3G sub-district can be done in Yu Xia 30 2G adjacent areas, can be expressed as B1, B2 ..., B30.
Wait to delete the adjacent area and concentrate and to have comprised each 2G adjacent area to be deleted, these 2G adjacent areas to be deleted are to select according to the size order of weighted value separately.Wait to delete the adjacent area collection and can be expressed as D,, need treat deletion adjacent area collection and carry out initialization in the starting stage of carrying out the method for the invention.
In this step, from described current adjacent area collection A, remove the 2G adjacent area of waiting to delete among the collection D of adjacent area, and the current adjacent area that add to the 2G adjacent area of selection setting quantity from the alternative collection B of adjacent area is concentrated, thereby generates new current adjacent area collection A.
When waiting that deleting adjacent area collection D is empty set, can be directly from the current adjacent area collection A that add to the alternative 2G adjacent area that collects selection setting quantity the B, adjacent area.For example, it is 32 that the maximum of the 2G adjacent area quantity that can comprise is concentrated in current adjacent area, at present, has wherein comprised 2G adjacent area A1, A2 ..., A20 then at most can be to wherein adding the alternative concentrated B1 in adjacent area, B2 ..., B12, thereby generate new current adjacent area collection, the 2G adjacent area that wherein comprises is A1, A2,, A20, B1, B2 ..., B12.The quantity of setting also can be the subclass of adjacent area alternative collection B, as B1, and B2, B3, B4.
In the carrying out stage of the method for carrying out present embodiment, describedly wait to delete the adjacent area collection and may be empty set, also may be nonvoid set.If waiting to delete the adjacent area collection is empty set, then among the current adjacent area collection A that directly add to the 2G adjacent area of selection setting quantity from the alternative collection B of adjacent area; If waiting to delete adjacent area collection D is nonvoid set, then concentrate the current adjacent area that add to the 2G adjacent area of selection setting quantity from the alternative collection B of adjacent area, removes and the identical 2G adjacent area, 2G adjacent area of waiting to delete among the collection D of adjacent area.
Set the 2G adjacent area of quantity among the alternative collection B of the adjacent area of above-mentioned interpolation, can be the subclass of adjacent area alternative collection B, also can be the complete or collected works of adjacent area alternative collection B, concrete quantity of adding is decided on the maximum quantity of the 2G adjacent area that current adjacent area collection A can hold.The maximum quantity of supposing the 2G adjacent area that current adjacent area collection A can hold is K, and through after the above-mentioned interpolation and removal process, 2G adjacent area quantity among the current adjacent area collection A that forms is actual to be I, and then the result that need only form at last of the operation in this step satisfies I≤K and gets final product.
Behind system's operation certain hour, can be according to the switch instances of terminal between 2G cell and 3G sub-district, the measurement result of each 2G adjacent area among the current adjacent area collection A of statistics terminal to report is promptly added up the current adjacent area of terminal to report in the certain hour and is concentrated each 2G signal quality of adjacent cells and quality of handoff.Wherein, the data of quality of handoff comprise that terminal switches to the number of times of each 2G adjacent area and/or handover success number of times or handoff failure number of times (or handover success rate, handover failure rate) and relevant traffic statistics index from current 3G sub-district.Concentrate the statistical value of each 2G signal quality of adjacent cells and quality of handoff data when the current adjacent area of terminal to report and reach the threshold value of setting, or system operation time finishes statistic processes when reaching set point; Otherwise, repeat statistic processes, when satisfying the condition of above-mentioned statistic processes end, statistic processes just finishes.
In the communication system dynamic operation, terminal switches to the situation possibility of the 2G adjacent area among the current adjacent area collection A because factors such as weather, signal quality, cell environments, and appear in the system operation time of setting, terminal does not have in the 2G adjacent area of the actual 2G of switching to adjacent area collection A, the number of times that perhaps switches to the 2G adjacent area among the collection A of 2G adjacent area is less, thereby does not reach the target of statistics.Therefore, in this step, need judge the 2G signal quality of adjacent cells of terminal to report and the statistical value of quality of handoff data, have only this statistical value to reach when setting threshold value, or system operation time just finishes this step 104 when reaching set point, then execution in step 105.
By each 2G signal quality of adjacent cells and quality of handoff among the current adjacent area collection A, promptly switching times and handover success rate are pressed the weighted value of each 2G adjacent area correspondence of predefined weight calculation separately.
Suppose that above-mentioned 2G signal quality of adjacent cells is expressed as Q, the switching times that switches to corresponding 2G adjacent area from current 3G sub-district is expressed as S, and success rate for switching is expressed as R, then the weight of above-mentioned each data correspondence can be expressed as Wq, Ws, Wr respectively.Each weight is the embodiment of the attention degree of 2G signal quality of adjacent cells, switching times, handover success rate to correspondence.
Signal quality Q is the prerequisite of switching.In embodiments of the present invention, for the signal quality that does not satisfy switching condition, less than-90dBm, its corresponding Q value is decided to be 0 as signal quality; Signal quality is in-and 90dBm is between-the 85dBm time, and corresponding Q value is 1; Signal quality is in-and 85dBm is between-the 80dBm time, and corresponding Q value is 2; Signal quality is in-and 80dBm is between-the 75dBm time, and corresponding Q value is 4; Signal quality is during greater than-75dBm, and corresponding Q value is 5, and the like.When specifically adding up, the mean value of the desirable certain hour Q value at interval, signal quality Q value is high more, and the 2G neighbor cell configuration of representing correspondence is that the priority of adjacent area of this 3G sub-district is high more.
Switching times S represents that terminal switches to the number of times of corresponding 2G adjacent area or the frequency that switching behavior takes place from current 3G sub-district, switching times S is big more, the expression terminal is big more from the mobile necessity that current 3G sub-district switches to this 2G adjacent area, so, this 2G cell need be configured to the adjacent area of current 3G sub-district more.
Handover success rate R represents to switch to from current 3G sub-district the mobile cutting off rate of corresponding 2G adjacent area, and handover success rate R is high more, and corresponding mobile cutting off rate is low more, and it is high more to represent that this 2G cell is configured to the priority of adjacent area of this 3G sub-district.
Under different scenes, need configuration different weights Wq, Ws, Wr, to embody attention degree to signal quality, switching times, handover success rate.Usually, the attention degree of Wq, Ws, Wr can be set to Wq＜Ws＜Wr, like this, each 2G adjacent area in 2G neighbor cell configuration collection C all can calculate a corresponding weighted value Z=Q*Wq+S*Ws+R*Wr, for participating in the 2G adjacent area of repeatedly calculating, can get maximum or other calculated value (for example, mean value) of weighted value Z.
The weighted value Z of the 2G adjacent area of coming out according to aforementioned calculation when its numerical value is big more, shows that corresponding 2G adjacent area has bigger priority to be configured to the adjacent area of current 3G sub-district.
The size of the weighted value that obtains by aforementioned calculation sorts to the 2G adjacent area among the current adjacent area collection A, can such as ordering from small to large, also can be to sort from big to small according to certain rule.In the present embodiment, choose 2G adjacent area new the waiting of generation of setting quantity according to the ascending order of weighted value and delete adjacent area collection D.Described here " setting the 2G adjacent area of quantity " promptly can be according to the weighted value ordering, and according to the adjacent area of the setting quantity of ascending selective sequential, and the quantity that each circulation sets can be the same or different; Also can be to current adjacent area collection, next time the quantity of alternative concentrated selection adjacent area and the configurable 2G of adjacent area collection adjacent area from the adjacent area peak judge that the back determines, promptly judge the adjacent area quantity that concentrate current adjacent area, add the quantity of alternative concentrated selection adjacent area next time from the adjacent area, whether less than the peak of the configurable 2G of adjacent area collection adjacent area, if, then described " setting quantity " is 0, and new waiting is set, and to delete the adjacent area collection be empty set; If not, then be provided with and wait to delete the adjacent area to concentrate the quantity of adjacent area be that current adjacent area concentrates adjacent area quantity to add the quantity sum of the above next time of alternative concentrated selection adjacent area from the adjacent area, poor with the peak of the configurable 2G of described current adjacent area collection adjacent area, afterwards, according to the ascending order of described 2G adjacent area weighted value, select the 2G adjacent area to delete the adjacent area collection as new waiting.
In the present embodiment, need judge whether can be configured to the 2G adjacent area of current 3G sub-district to determine each 2G adjacent area to all 2G adjacent areas among the alternative collection B of adjacent area.Therefore, when having the 2G adjacent area of judging as yet among the alternative collection B of adjacent area, just need return execution in step 102, delete the alternative collection of adjacent area collection and adjacent area according to described current adjacent area collection, new waiting, generate new current adjacent area collection once more, and continue to calculate the weighted value of each 2G adjacent area.
Because the limited amount of open ended 2G adjacent area among the current adjacent area collection A, and add the 2G adjacent area quantity of waiting to delete among the collection D of adjacent area after each flow process to also is limited, therefore, may need several flow processs just can finish judges all 2G adjacent areas among the alternative collection B of adjacent area.After each flow process, all the weighted value according to each 2G adjacent area sorts, and selects the 2G adjacent area of the little setting quantity of weighted value to add to and waits to delete among the collection D of adjacent area, finishes the renewal for the treatment of deletion adjacent area collection D.
In the present embodiment, can be from all 2G adjacent areas through weighted value calculating, selecting the 2G neighbor cell configuration of the big setting quantity of weighted value is the 2G adjacent area of current 3G sub-district.Carry out the repeatedly flow process of present embodiment in circulation after, when no longer including the 2G adjacent area of not adding to as yet among the current adjacent area collection A among the alternative collection B of adjacent area, can be according to the weighted value of all 2G adjacent areas of the current 3G sub-district correspondence that calculates, according to the descending order of weighted value, the corresponding 2G neighbor cell configuration of the setting quantity that weighted value is big is the 2G adjacent area of current 3G sub-district.For example, after the weighted value ordering, each 2G adjacent area is followed successively by A1 by the descending sequence arrangement of weighted value, A2 ... A20, B1, B2 ..., B30, so, can select preceding 32, also can select sub-district less than this quantity, for example 20, as the 2G adjacent area of current 3G sub-district.
In the embodiments of the invention, as a kind of simplification, also can directly the descending order of each 2G adjacent area weighted value be concentrated in the current adjacent area that forms at last, with the 2G neighbor cell configuration of wherein setting quantity is the 2G adjacent area of current 3G sub-district, these set of setting the 2G adjacent area of quantity both can be the subclass of current adjacent area collection, also can be the complete or collected works of current adjacent area collection.
In the present embodiment, by the alternative collection in adjacent area being set and waiting to delete the adjacent area collection, on the basis of current adjacent area collection, add automatically and the deletion adjacent area, generate new current adjacent area collection and operational system, concentrate each 2G signal quality of adjacent cells by adding up current adjacent area, switching times, handover success rate, thereby calculate the weighted value of each 2G adjacent area, and then be the 2G adjacent area of 3G cell configuration according to the selective sequential of weighted value, make to optimizing as far as possible the 2G adjacent area of 3G cell configuration, the inaccuracy that has overcome artificial subjective estimation or be configured with reference to the 2G adjacent area with the site has solved owing to reasons such as environmental change make the 3G sub-district occur mismatching, the problem of 2G adjacent area is joined in leakage.And, also solved under the drive test condition, owing to can't carry out whole drive tests as resident place of residence, high building, office etc., thereby cause the mismatching of 2G adjacent area, leak and problem such as join in some special places.Simultaneously, by the alternative collection in adjacent area being set and waiting to delete the adjacent area collection, realized that weighted value is carried out in all 2G adjacent areas of 3G sub-district correspondence to be calculated, make and well solve the 3G sub-district and mismatch, leak the problem of joining the 2G adjacent area in the 2G adjacent area that can in all 2G adjacent area scopes, be chosen as the 3G cell configuration in real time, efficiently, accurately.
Second embodiment
Fig. 2 is the apparatus structure schematic diagram of 3G cell configuration 2G adjacent area in the second embodiment of the invention, described for the device of 3G cell configuration 2G adjacent area comprises initial setting up unit, generation unit, measuring unit and optimizes the unit as shown in Figure 2, wherein,
The initial setting up unit is used to be provided with and the current 2G neighbor cell configuration collection of initialization is a current adjacent area collection, concentrates from the configurable 2G adjacent area of 3G sub-district and selects the 2G adjacent area to form the alternative collection in adjacent area, and setting and initialization wait to delete the adjacent area collection.The initial value of described current adjacent area collection is that initial time is the set of each 2G adjacent area of 3G cell configuration, i.e. the current 2G neighbor cell configuration collection of 3G sub-district correspondence.The alternative collection in adjacent area is the set of concentrating the 2G adjacent area composition of selecting from the configurable 2G adjacent area of 3G sub-district.Wait to delete the adjacent area and concentrate and to have comprised each 2G adjacent area to be deleted, need initialization.
Generation unit is according to the initialization result of initial setting up unit, promptly current adjacent area collection, waits to delete the alternative collection of adjacent area collection and adjacent area, generates new current adjacent area collection.At next this circulation time, generation unit is deleted the alternative adjacent area that will add of concentrating of adjacent area collection and adjacent area with waiting of obtaining of current adjacent area collection, last time, generates new current adjacent area collection.Be specially, from current adjacent area collection A, remove the 2G adjacent area of waiting to delete among the collection D of adjacent area, and the current adjacent area that add to the 2G adjacent area of selection setting quantity from the alternative collection B of adjacent area is concentrated, thereby generate new current adjacent area collection A.Wait to delete the adjacent area collection and may be empty set, also may be nonvoid set.When waiting that deleting adjacent area collection D is empty set, generation unit can be directly from the current adjacent area collection A that add to the alternative 2G adjacent area that collects selection setting quantity the B, adjacent area.If waiting to delete adjacent area collection D is nonvoid set, then concentrate the current adjacent area that add to the 2G adjacent area of selection setting quantity from the alternative collection B of adjacent area, removes and the identical 2G adjacent area, 2G adjacent area of waiting to delete among the collection D of adjacent area.Set the 2G adjacent area of quantity among the alternative collection B of the adjacent area of above-mentioned interpolation, can be the subclass of adjacent area alternative collection B, also can be the complete or collected works of adjacent area alternative collection B, each quantity of adding can be identical or different.Concrete quantity of adding is decided on the maximum quantity of the 2G adjacent area that current adjacent area collection A can hold.The maximum quantity of supposing the 2G adjacent area that current adjacent area collection A can hold is K, and through after the above-mentioned removal and interpolation process, 2G adjacent area quantity among the current adjacent area collection A that forms is actual to be I, and then the result that need only form at last of the operation in this step satisfies I≤K and gets final product.
Measuring unit is used to add up the measurement result of each adjacent area that obtains according to new current adjacent area transporting something containerized row system, and described measurement result is sent to the optimization unit.After generation unit generates new adjacent area collection, operational system, behind the certain hour, can be according to the switch instances of terminal between 2G cell and 3G sub-district, by the measurement result of each 2G adjacent area among the current adjacent area collection A of measuring unit statistics terminal to report, promptly add up the current adjacent area of terminal to report in the certain hour and concentrate each 2G signal quality of adjacent cells and quality of handoff.Wherein, the data of quality of handoff comprise that terminal switches to the number of times of each 2G adjacent area and/or handover success number of times or handoff failure number of times (or handover success rate, handover failure rate) and relevant traffic statistics index from current 3G sub-district.
Optimize the unit, be used for the measurement result that sends according to measuring unit, calculate the weighted value of each 2G adjacent area correspondence, and be the 2G adjacent area of 3G sub-district according to the neighbor cell configuration that quantity is set in the selective sequential of weighted value.
The 3rd embodiment
Fig. 3 is the apparatus structure schematic diagram of 3G cell configuration 2G adjacent area in the third embodiment of the invention, as shown in Figure 3, on basis shown in Figure 2, described optimization unit specifically comprises computing unit, judging unit and dispensing unit.Wherein,
Computing unit be used to judge whether the measurement result that measuring unit sends reaches default thresholding, or whether system operation time arrives set point, if, then calculate the weighted value of described each 2G adjacent area, sorted in the 2G adjacent area, and new waiting is set deletes the adjacent area collection according to described weighted value.
In the communication system dynamic operation, in the system operation time of setting, may not reach the target of statistics.Therefore, need judge the 2G signal quality of adjacent cells of terminal to report and the statistical value of quality of handoff data, have only this statistical value to reach when setting threshold value, or system operation time is when reaching set point, just calculate the weighted value of described each 2G adjacent area, according to described weighted value sorted in the 2G adjacent area, and new waiting is set deletes the adjacent area collection.When computing unit calculated the weighted value of each 2G adjacent area correspondence, according to each 2G signal quality of adjacent cells and quality of handoff among the current adjacent area collection A, promptly switching times and handover success rate were pressed the weighted value of each 2G adjacent area correspondence of predefined weight calculation separately.The weighted value Z of the 2G adjacent area of coming out according to aforementioned calculation when its numerical value is big more, shows that corresponding 2G adjacent area has bigger priority to be configured to the adjacent area of current 3G sub-district.
