To solve the joint call admission control problem in heterogeneous network environment of single operator

a novel admission control algorithm based on immune computing was proposed.The mathematical model of joint call admission control problem was expounded

the framework of admission control solution based on immune multi-objective optimization algorithm was given

and simulation experiments were done to validate proposed solution.Experimental result shows that the proposed solution

compared with other solutions

obtains better performance tradeoffs between recent utility and frequency spectrum

balances preferably each radio access network of the same operator

and has the advantage of good application value.
