From this table, the indispensable configuration data of base station only has 85, only accounts for 36% of configuration data total amount.The community amount of the average RNC of existing network is about 400, when therefore RNC occurs abnormal, needs the data of disaster tolerance to taper to more than 3,000 from the order of magnitude up to ten thousand.
Corresponding, disaster recovery method of the present invention as shown in Figure 4, comprising:
Obtaining step 41, when needing to carry out disaster tolerance to the primary RNC of the target under TD-SCDMA network, only obtains the indispensable configuration data of second line of a couplet base station corresponding to the primary RNC of target to disaster recovery database; Wherein, described indispensable configuration data is base station is the data that operation business must be configured by RNC; The described disaster recovery database indispensable configuration data of each base station under preserving TD-SCDMA network; The second line of a couplet base station that the primary RNC of described target is corresponding belongs to described TD-SCDMA network;
Steps for importing 42, is directed into target RNC for subsequent use by the indispensable configuration data of second line of a couplet base station corresponding for primary for described target RNC;
Perform step 43, perform the switching of the primary RNC of described target and described target RNC for subsequent use.
The indispensable configuration data that directly can obtain second line of a couplet base station corresponding to the primary RNC of mark from disaster recovery database of the present embodiment, compared to prior art, do not need from whole network data, to filter out disaster tolerance data again, therefore disaster tolerance is consuming time shorter.In addition, because indispensable configuration data is simplified relatively, therefore import, derive and consuming timely obtain effective reduction, thus further increase the disaster tolerance speed of RNC.
In addition, consider that the data type of the indispensable configuration data of each base station is the same in fact, just there is change in numerical value, and therefore this feature of pin of the present invention provides a kind of concrete screening technique, and namely above-mentioned screening step 35 comprises:
Step 351, sets up Filter Engine based on genetic algorithm, and using the screening conditions of the data type of indispensable configuration data as Filter Engine
Step 352, filters out the indispensable configuration data of each base station under described TD-SCDMA network from the whole network data of network management center by described Filter Engine.
Genetic algorithm is the effective ways being usually used in selection variables data at present, in the present embodiment, the data type of indispensable configuration data is regarded as the hereditary feature (i.e. each base station exist hereditary capacity) of all base stations, according to this hereditary feature as screening conditions, from whole network data, filter out the different variablees corresponding to each hereditary feature, these variablees are exactly the specifying information that base station needs configuration.
In addition, the order importing indispensable configuration data to RNC for subsequent use also determine the execution speed of disaster tolerance.Indispensable configuration data is specifically divided into resource binding data, the transmission connection data and community setting data of base station by the present invention for this reason.Exemplarily, community setting data specifically can comprise the signal strength signal intensity of generation community, base station.In the process of data importing, the signal strength signal intensity of community cannot import RNC for subsequent use prior to resource binding data, transmission connection data, and namely when Resourse Distribute and transmission link are not determined, RNC for subsequent use cannot determine the signal strength signal intensity of community.Therefore, in above-mentioned steps for importing 42, because the resource binding data of second line of a couplet base station corresponding for primary for described target RNC, transmission connection data and community setting data being directed in described target RNC for subsequent use according to preset order.Described preset order is that resource binding high priority data has precedence over community setting data in transmission connection data, transmission connection data.
