PURPOSE: A number translation method according to trunk groups in an intelligent network switching point is provided to apply trigger criteria, for getting an intelligent service through the establishment of private network number plans according to subscriber groups, to the trunk groups, so that every trunk group has a unique number plan. CONSTITUTION: An IAM(Initial Address ISUP(ISDN(Integrated Services Digital Network) User Part) Message) is received from a relay switching point(S31). A CCF(Call Control Function) entity of a corresponding intelligent network switching point reports whether a subscriber is registered as an intelligent network subscriber to an SSF(Service Switching Function) entity(S32). The SSF entity checks whether a trigger coincident with a trigger of the reported subscriber exists(S33). If not, general call processing is performed, and if exists, whether the trigger is for a subscriber group is checked(S34). If not, processing of a corresponding trigger is performed(S42), and if so, an identification item on a number translation table is checked(S35). The SSF entity requests number collection to the CCF entity(S36), and the CCF entity delivers collected numbers to the SSF entity(S37). The SSF entity performs number translation to check whether a defined condition is satisfied(S38). If so, the SSF entity requests an intelligent network service to an SCP(Service Control Point)(S39) and processes an intelligent network call(S40). And if the defined condition is not satisfied, an intelligent network call is processed as failure(S43).
