As shown in Figure 3, the operator has both 2G and 3G networks. In order to enable users to obtain higher-speed services, multimode terminals that normally support 2G/3G will reside in the 3G network. . However, in the case of particularly large traffic along the subway, if you continue to let users stay in 3G preferentially, it may cause network congestion or even overload. In order to reduce the load on the 3G network without affecting the user's service experience, all circuit switched (CS) services within the 3G can be migrated to the 2G. The process can include the following processing steps:

Step S302: The operator writes the service application APP through the interface provided by the SDN controller, and describes the personalized network service requirement: the monitoring indicator, the triggering condition and the constraint condition when the CS service is busy, and the action in each scenario.

(5) When the conditions for using the A group parameters are satisfied, the A group parameters are used;

(6) When the conditions for using the A group parameters are not satisfied, the B group parameters are used.

Step S304: The SDN controller instructs the 2G/3G radio access network RAN to report the working state and/or system load of the 2G/3G cell according to the setting of the service application APP requirement.

Therefore, operators hope to implement energy-saving control for these indoor base stations when no one is using them. The process can include the following processing steps:

Step S402: The operator can write a service application APP through the interface provided by the SDN controller to describe the personalized network service requirement:

(1) Demarcation of U1011, ..., U3281 for the designated office building and the subway along the indoor reinforcement with the coverage base station group OfficeMetroBaseStationGroup;

(2) Set the conditions for indoor reinforcement and coverage of base stations for energy-saving control:

(Time period: 0:00 to 5:00)

And (strengthen the coverage of the base station load <10%)

And (basic coverage base station load <70%)

(3) The decision timing for setting the condition in (2) is: every 10 minutes, the base station load is reported, and the base station energy-saving status is reported;

(4) Perform energy-saving control on the base station that meets the energy-saving control conditions in the OfficeMetroBaseStationGroup group; when the energy-saving state is not met in the OfficeMetroBaseStationGroup group, the energy-saving control is exited and the working state is restored.

Step S404: The SDN controller instructs the radio access network to report the load information and/or the energy saving state information of the designated base station in the time range from 0:00 to 5:00 according to the setting of the service application APP requirement.

Step S406: The radio access network reports the load information and/or the energy saving state of the designated base station according to the indication.

Step S408: When receiving the load information and/or the energy-saving state of the reported base station, the SDN controller checks whether the above condition is satisfied. When no event is reported, the SDN controller checks whether the condition is satisfied in a period of 10 minutes.

Step S410: When the SDN controller determines that a certain base station needs to enter the energy-saving state or exits the energy-saving state, the OLT controller directly sends the energy-saving control indication of the base station to the OMC.

Step S412: After receiving the energy-saving control update indication of the specific base station, the OMC updates the parameter configuration of the energy-saving control of the designated base station to the RNC.

Step S414: The RNC performs energy saving control on the designated base station.
