摘　　要：针对现有平台实时处理能力的不足,在HLR系统中引入了基于双数据库模式的Cache机制。提出了结合LRU算法和LFU算法两者优点的SLRU替换算法,该算法保证了Cache机制的高效稳定运作,从而大大提高了整个HLR系统的实时处理能力。Aiming at the deficiency of the present platform in the real-time processing ability,Cache mechanism based on diploid-database mode is used in HLR.The SLRU replacement algorithm which colligates the advantages of LRU and LFU is brought forward,and guarantees the operation of the Cache mechanism in an effective and steady way.As a result,the real-time processing ability of the HLR system is enhanced greatly.
