PRERECORDING METHOD USING ROUTE SEQUENCE IN SWITCHING SYSTEM

摘要

PURPOSE: A prerecording method using route sequence in switching system is provided to remove the re-number translation course when trying a call, by allocating the route sequence at generating an identification code of enterpriser network. CONSTITUTION: A prerecording method using route sequence in switching system comprises the steps of;translating the number when trying a call(201);determining whether the corresponding call is the trunk call(202);processing the generalized call when the corresponding call is not the trunk call(203);confirming whether the user is a prerecording subscriber when the corresponding call is the trunk call(204);determining whether the route sequence is prerecorded when the user is a prerecording subscriber(205);grasping the call type of corresponding call when the route sequence is a prerecorded way, obtaining the number of route sequence and requesting the routine(206-207);and requesting the routine after re-number translation by inserting the network identification code, when the route sequence is not a prerecorded way(208-210).
