Abstract: A radio resource allocation method and a radio network controller. The method includes obtaining transmission rate information of a plurality of links at time points t1, t2, . . . , and tn, overall traffic volume information of the plurality of links in time periods T1, T2, . . . , and Tm, and radio resource use information of each wireless transmission unit (WTU) in the plurality of WTUs, predicting a first transmission rate of a first link at a time point tn+1 in a time period Tm+1 according to the transmission rate information of the plurality of links at t1, t2, . . . , and tn and the overall traffic volume information of the plurality of links in T1, T2, . . . , and Tm, and determining a path that can satisfy a transmission rate requirement of the first link, and allocating a radio resource of the first link.

Abstract: The present invention relates to a method for controlling cache mapping and a cache system. The method includes: changing, at a preset time interval, a target data block in a cache of an underlying storage medium, where at least one data block in the underlying storage medium is mapped to the target data block, one or more data blocks in the underlying storage medium are mapped only to one target data block in the cache, the cache of the underlying storage medium includes a flash memory medium, and the changed target data block in the cache includes the target data block currently having the maximum number of erasure times in the cache. By utilizing the technical solution, the service life of the flash memory medium can be optimized.
