Fig. 1 is that the sub-district of of the prior art 2 layers of 19 topology covers sketch map.As shown in Figure 2, whole sub-district is made up of 19 constituent parts sub-districts, and with the 1-19 sign, the initial point fetch bit of emulation coordinate system is in the central point of the unit sub-district (sub-district 1) in centre position respectively.Sub-district with these 2 layers of 19 topologys is covered as example below, and existing user distribution algorithm is described, and comprises the steps:
(a) confirm user's radius at random.User's radius need be less than the maximum radius of whole sub-district; If the vertical radius of unit sub-district is cellr; User's radius is ueradius, and then as can beappreciated from fig. 1 user's radius needs 5 times cellr, then uses following formula (1) to produce user's radius ueradius;
ueradius＝rand(1)×5×cellr (1)
Wherein, rand (1) expression generates the random number between 0～1.
(b) confirm user's angle at random.User's angle is random distribution between (0,2 π), and promptly user's angle ueangle may be calculated:
ueangle＝rand(1)×2π (2)
The position uep that therefore can obtain the user is:
uep＝ueradius×(cos(ueangle)+isin(ueangle)) (3)
Wherein, cos representes sin cos functions, and sin representes SIN function, and i is an imaginary unit.
(c) confirm cell range, find out off-limits user.
The straight border of sub-district can be represented by y=kx+b, and the border of whole sub-district shown in Figure 1 is by 30 rectilinear(-al)s, different straight border intercept, slope and starting point different.According to real part and the imaginary part of customer location uep, i.e. the weighing apparatus coordinate of user's coordinate judges in the emulation coordinate system and the ordinate border that whether exceeds the sub-district.
(d) dwindle the user's who exceeds cell range radius, it is in the cell range, that is:
uep＝ueradius×rand(1)×(cos(ueangle)+isin(ueangle))
(4)
In this step; The method of dwindling user's radius is the random number that is multiplied by between 0～1; Therefore possibly take advantage of for the first time that user's radius still exceeds cell range after the random number, therefore continue to take advantage of the random number between 0～1, till user's radius is in cell range.
Obtain a user who is distributed in the cell range through above-mentioned steps.The user that all are sprinkled in emulation calculates through above-mentioned steps.
But there is following shortcoming in existing above-mentioned user distribution method: 1) needs are confirmed the border of sub-district, and when sub-district number and change in radius, the border of sub-district also changes thereupon, so ambiguity increases; 2) need the judges radius whether to exceed cell boarder, this just needs to judge position and the distance between the base station and the angle of each sub-district, and computation complexity is high; When 3) adjusting user radius is to cell range, need calculate for each off-limits user, and a user possibly need to calculate repeatedly according to the scope of existing distance of user and sub-district.
In sum, in mobile communication system simulation, existing user layout method calculation of complex, efficient is low.
