As shown in Figure 1, the method flow diagram for the physical layer identifications of automatic allocating cell in the embodiments of the invention comprises the steps:
Step 101, be a plurality of subregions with the area dividing around the eNB;
Zone around the eNB in this step can be set to, and the position that belongs to eNB is a circle in the center of circle, and the value of the radius that this is circular can be set according to actual conditions, also can other shapes be arranged in the zone around this eNB certainly.Zone around the eNB is set to position with the eNB place when being the center of circle circular, can be the center of circle with should circle being divided into uniformly with eNB, and the γ degree is a plurality of sector regions of central angle; Referring to Fig. 2, the position at A point expression eNB place is 8 sub regions of subregion 1~subregion 8 with the area dividing around the eNB among the figure; Wherein each subregion is the center of circle for the position of ordering with A; Central angle is the sector region of 45 degree, and this sector region is meant the similar fan-shaped zone that is made up of the central angle and the center of circle, and the radius of this sector region is relevant with this eNB performance; When the eNB performance is strong; Can receive longer-distance wireless signal, this moment, the radius of this sector region was just longer, did not limit the concrete shape of above-mentioned subregion in an embodiment of the present invention.
For the ease of understanding, be that example is introduced only below this subregion is arranged to sector region.The value of above-mentioned γ degree, just the number of degrees of this central angle are selected 10 degree, 15 degree, 20 degree, 30 degree, 45 degree etc. for use.Because this subregion is a sector region; So this eNB of the big I of these central angle number of degrees decision institute can obtain wireless signal in the peripheral region how much; When the number of degrees of this central angle are provided with when bigger, for example 90 degree, 120 degree are because the area that this sector region covers is bigger; This eNB can obtain more wireless signal; But the wireless signal with respect to receiving whole space can reduce the influence of interference signal to echo signal to a certain extent, has improved the success rate to the wireless signal demodulation that receives the sub-district; And be provided with when smaller when this central angle, for example 10 degree, 20 degree etc., this moment, this eNB can obtain less wireless signal, can significantly improve the success rate to the wireless signal demodulation that receives the sub-district because the area that this sector region covers is less.Introduced the quantity that controls the received wireless signal of eNB through the central angle of adjusting this sector region above; And then adjust success rate to the wireless signal demodulation that receives the sub-district, be exactly through the performance of the antenna of adjustment radio scanner or eNB, the number of degrees that this central angle is controlled in sensitivity in concrete operations.Certainly also can control the quantity of the received wireless signal of eNB through the radius of adjusting this sector region.
Step 102, receive wireless signal in each subregion respectively,, obtain the physical layer identifications of the sub-district in each subregion through the wireless signal that demodulate reception arrives;
In order to follow two principles of giving the cell configuration physical layer identifications in the prior art, need obtain the eNB physical layer identifications of all sub-districts on every side in the present embodiment.Just, receive the wireless signal in each sector region respectively,, obtain the physical layer identifications of the sub-district in each said sector region through the said wireless signal that demodulate reception arrives according to clockwise or be rotated counterclockwise the mode of γ degree.Referring to Fig. 2, suppose at first to obtain the wireless signal in the subregion 1, the wireless signal that arrives through demodulate reception; Obtain the physical layer identifications of the sub-district in the subregion 1; Turn clockwise then 45 the degree, do same operation, by that analogy; Up to having rotated 360 degree, just obtained from the physical layer identifications of subregion 1~subregion 8 interior sub-districts.Certainly also can obtain the physical layer identifications of sub-district in all subregions according to the mode that is rotated counterclockwise.When employing turns clockwise or during the mode that is rotated counterclockwise,, also just obtained the physical layer identifications of sub-districts in all subregions when having rotated 360 when spending.
Do not limit the sequencing that obtains the physical layer identifications of sub-district in each subregion in the present embodiment, for example can be in a certain order (as: clockwise or counterclockwise), perhaps according at random mode.
In this step, in the wireless signal that demodulate reception arrives, also can obtain the peripheral cell positional information of this eNB relatively; For example sub-district A is in the west side of this eNB; Sub-district B is in the east side of this eNB, and sub-district C is in southeast side of eNB etc., and the positional information of obtaining can be used for doing neighboring BS relationship optimization by eNB.
Step 103, obtain the physical layer identifications of the sub-district in all subregions after, be the physical layer identifications physical layer identifications inequality of the sub-district in one of the cell configuration of eNB service and all subregions.
Just, follow all different physical layer identifications in all sub-districts of detecting for the cell selecting that eNB served.
Can know by technique scheme; Through being a plurality of subregions, receive the wireless signal in each subregion then respectively, with respect to receiving in whole space with the area dividing around the evolution base station; The quantity of the feasible wireless signal that receives reduces a lot; Just mean that also the interference to echo signal reduces, thereby improved the success rate of the wireless signal of demodulation single subdistrict, and in the physical layer identifications that obtains peripheral cell; The relative position information of each sub-district around also can knowing, this can be used for doing neighboring BS relationship optimization by eNB.
In order better to understand embodiments of the invention; Introduce embodiments of the invention below in conjunction with Fig. 2 and concrete example; In this embodiment; ENB obtains the wireless signal of peripheral cell through radio scanner or reception antenna, and wherein the value of γ degree is confirmed according to the performance of radio scanner or reception antenna, sensitivity etc. are autonomous by eNB, for example 10 degree, 15 degree, 20 degree, 30 degree, 45 degree etc.The step of this method is following:
After step 1, the newly deployed eNB start; At first select an inceptive direction; Use radio scanner or reception antenna in subregion, to receive wireless signal; And carry out the demodulation of wireless signal, obtain the physical layer identifications of the sub-district in the subregion, and the current location information of subregion with this cell association together;
For example this inceptive direction is chosen as the direction of subregion 1, obtains the wireless signal in other subregions through rotation sweep receiver or reception antenna then.
Step 2, eNB radio scanner or reception antenna on horizontal plane clockwise or be rotated counterclockwise the γ angle; Receive and the demodulation wireless signal in the subregion on new direction; Obtain the physical layer identifications of the sub-district in the subregion, and write down the positional information of this subregion;
Step 3, repeated execution of steps two are up to all subregions been scanned all;
According to clockwise or counterclockwise rotation sweep receiver or reception antenna, rotated 360 degree up to this radio scanner or reception antenna, can draw all been scanned of all subregions this moment.
