随着现有2G网络容量持续不断扩大,3G也已经近在眼前,未来IMS的远景更是令人期待。但现有的HLR产品在面向3G/IMS演进的条件下,其局限性日益显现出来:首先是容量限制,随着移动用户的不断增加,现有H L R产品的容量一般难以超越百万量级,难以满足现在移动用户迅速增加的现状。其次,
With the continuous expansion of the existing 2G network capacity, 3G is also close at hand. The future prospect of IMS is even more promising. However, the existing HLR products are becoming more and more limited in the face of the evolution of 3G / IMS. The first is the capacity limitation. With the continuous increase of mobile subscribers, the capacity of the existing HLR products generally can not exceed one million orders of magnitude, Difficult to meet the rapid increase of mobile users now the status quo. Second,
