Embodiment
Load control action such as cell load control action are a kind of important means of system held network stabilization, load control action such as cell load control action and network system efficient and network capacity etc. are closely related, therefore, load control action such as cell load control action are very important network performance indexes.By load control action such as cell load control action are measured, can provide favourable foundation for the network optimization.
Be example with the cell load control action below, the network optimized approach that embodiment of the present invention is provided describes.Of particular note, though following execution mode is that example describes with the cell load control action,, the load control action in the embodiment of the present invention is not restricted to the cell load control action.
At first, the cell load control action is measured.Embodiment of the present invention can be measured the number of times of accumulative total metering system here such as cell load control action execution in the cycle etc. to the cell load control action by CC (accumulative total is measured) mode.Embodiment of the present invention also can be measured the cell load control action by GAUGE (dynamic variable measurement) mode, can also measure the cell load control action by alternate manner.Embodiment of the present invention does not limit the mode that the cell load control action is measured.And the measurement here can be the measurement based on RNC, also can be the measurement based on the sub-district.Measurement based on RNC is promptly measured the cell load control action in the RNC scope, the number of times of carrying out as cell load control action in the measure R NC etc.Measurement based on the sub-district is promptly measured the cell load control action in cell range, as measuring the cell load control action is carried out in the sub-district number of times etc.Embodiment of the present invention also can be measured the cell load control action in other regional extent.Embodiment of the present invention is the concrete manifestation form of restricted area scope not.
Cell load control action in the embodiment of the present invention can comprise following one or multinomial: the alien frequencies load is switched, the professional reduction of speed of BE, uncontrollable real time business QoS are consulted again, CS (Circuit Switched, circuit switching) the different system load switching in territory, PS (Packet Switched, packet switching) the different system load switching in territory, AMR (Adaptive Multi-Rate, adaptive multi-rate) voice reduction of speed, BE (Best Effort, doing one's best) professional TF (Transport Format, transformat) control and user operation such as discharge.Embodiment of the present invention is the content that specifically comprises of restricted cell load control action not.
When the cell load control action is measured, can also carry out the measurement of cell load control action respectively according to different types of service.The division of concrete type of service can be carried out according to the actual conditions in the network, as being with multiple different delineation of activities: session service type, stream type of service, interactive service type, background service type.Embodiment of the present invention is the concrete dividing mode of limit service type not.By the cell load control action being measured, the situation that influences to network performance of different service types can be provided, thereby provide favourable foundation for operator's adjustment business according to different service types.
After the measurement of having carried out above-mentioned cell load control action, can determine strategy according to measurement result, and network is optimized processing according to this strategy to the network optimization.That is to say that embodiment of the present invention can be come problem that the fixer network performance exists, network anomaly etc. according to measurement result, thereby can determine the strategy of the network optimization according to these problems, phenomenon etc., and carries out the network optimization and handle.The network optimization strategy here can be various strategies of the prior art, as adjusting access service, the network capacity extension etc.That is to say that the network optimization in the embodiment of the present invention is handled can be diverse network optimization process operation of the prior art.The not concrete operations handled of the concrete manifestation form of limiting network optimisation strategy and the network optimization of embodiment of the present invention.
