A method and system for downlink channelization code allocation or assignment in a Universal Mobile Telecommunication System (UMTS) are presented. The method and system generate an optimal channelization or Orthogonal Variable Spreading Factor Orthogonal Variable Spreading Factor (OVSF) code to be assigned to a new channel through a route having the minimum influence while maintaining the existing or assigned OVSF codes.
