How to build a height mass, the low cost operation network is the important problem that our future will solve.Extensive use TCP / IP agreement anastomosing , displaying a technology , business anastomosing general trend that digital technique , optical communication technique, the software engineering development sum unite at present especially with various technology. The former various barrier between the network specially, being some one specially appointed business but designing construction's is already more and more no obvious , the basis disappears in course of gradually , the network develops exactly to the direction fusing to IP with the technology coming to carve up a marketplace business. Building-up takes NGN as platform basis, use Softswitch under the control of is that the core network will be a future trend. It provides rich cut-over means tier in cut-over, the network the consumer of all kinds is linked being divided into group, rotates and the information form.We think "three nets-in-one " way therefore, will be informatization a direction of construction of public security within future segment of period , will be under the condition that business needs for being able to swear to satisfy unceasingly growing various, have an effect to make use of resource , cost reduction most, the overall raising public security system horizontal , is public security informatization provide the advantageous guarantee.
