14., it is characterized in that also comprising the steps: according to claim 6 or 10 or 11 described methods
Step 7: the accept business quality of service feedback of network of above-mentioned resource control function units, and dynamically adjust the underloading factor of logical network, if promptly the service quality of business network feedback does not meet the demands, then above-mentioned resource control function units is turned the underloading factor of counterlogic network down.
