An original hybrid method of channels assignment for DS-CDMA system is discussed in the paper. This method combines standard PN codes assignment policy and dynamic channel assignment procedure that minimise the cost of channel assignment. OPNET simulation model DS-CDMA system was used for assessment of the hybrid method. The results of simulation presented in the paper confirmed that the proposed method importantly improves the quality of services in the third generation cellular system.
