Claim One:
1. An uplink power control method based on a genetic algorithm in a communication network, comprising: A. modelling a communication network to acquire a theoretically optimal transmission power expression of a mobile terminal; B. determining a fitness function in combination of a genetic algorithm; C. determining the numbers of bits of binary strings of variables; D. initializing populations; E. returning an actual value from the binary string to serve as an actual variable; and F. obtaining the most robust gene and the weakest gene in a chromosome according to the fitness function, and designing a genetic operator and determining operating parameters of the genetic algorithm according to the most robust gene and the weakest gene; wherein, in the step F, roulette wheel selection is adopted to obtain the most robust gene and the weakest gene in the chromosome according to the fitness function, and the genetic operator is designed and the operating parameters of the genetic algorithm are determined according to the most robust gene and the weakest gene, the step F comprises: F 1 , calculating the fitness function eval(U k ) according to a decimal numerical value U k corresponding to each randomly generated binary chromosome, wherein this parameter K is mainly used for embodying random controllability of the genetic algorithm and an initial value of this parameter is artificially configurable: 
 eval( U k )=μ( t ) k= 1,2,3,.. . ; F 2 , calculating a sum of the fitness of the populations: F = ∑ k = 1 K ⁢ eval ⁡ ( U k ) ; F 3 , calculating a selection probability Y k corresponding to the U k of each chromosome: Y k = eval ⁡ ( U k ) F ; F 4 , calculating an accumulation probability Q k of the U k of each chromosome: Q k = ∑ j = 1 k ⁢ Y j ⁢ ⁢ k = 1 , 2 , 3 ⁢ ⁢ … ⁢ , K ; and F 5 , selecting one chromosome of a new population.
