The business model that has different scenes residential quarter in the existing network zones of different due to the network that moves therefore in this step, according to the division rule that sets in advance, is divided into scene residential quarters different more than two with existing network.For example existing network is divided into campus district, residential block, shopping centre and industrial area.And user distribution and service distribution in different scenes residential quarters are different, for example the FTP downloading service distributes more in the industrial area, in the district of campus QQ and the Fetion service distribution more, therefore can obtain different PDCH reusing degrees in different scenes residential quarters, what users are the extent for multiplexing of PDCH reusing degree reflection PDCH channel namely have jointly use at one time same PDCH channel.
In this step, for existing network operation, the bandwidth that needs in each scene residential quarter is not a changeless numerical value, and it has the wave characteristic of stochastic variable, and under different PDCH reusing degrees, the bandwidth that needs in each scene residential quarter has different wave characteristics.Gather by the Gb Interface between base station controller BSC and GPRS serving GPRS support node SGSN the bandwidth sample that each scene residential quarter needs, can obtain the wave characteristic of the bandwidth sample that needs in the scene residential quarter, for example, the bandwidth sample that the scene residential quarter that gathers at Gb Interface needs, the bandwidth sample that need in this scene residential quarter to obtain has the characteristic of normal distribution, does not have exponential distribution or other wave characteristics but do not get rid of the bandwidth sample that needs in this scene residential quarter.
Particularly, the probability distribution parameters of described bandwidth sample can be the variance of described bandwidth sample.The bandwidth sample of needs in each scene residential quarter that obtains according to step 202 calculates the probability distribution parameters of the bandwidth sample of described scene residential quarter.The bandwidth sample that the scene residential quarter that for example can gather at Gb Interface needs is then according to the variance of the described bandwidth sample of described bandwidth sample calculation.
