Telecom network fraud is not a statutory crime determined by competent authorities,but judicial normative documents establish independent charges and prescribe separate statutory penalties,making it essentially a quasi-crime.Comparing with common fraud,telecom network fraud is featured as techni-cal means,non-contact state,indeterminate victims and collusive organization.Among these features,the technical means are of a core feature,and the state feature is a derivative feature,both of which are internal characteristics,while the indeterminate victims and collusive organization are external features established based on the policy needs of reasonable delimitation and adjustment scope.Based on these four features,it is possible to reasonably distinguish telecom network fraud from common fraud,credit card fraud,theft or other Crimes.
