SUBSCRIBER CONFIRMATION SYSTEM AND A METHOD THEREOF CAPABLE OF CONFIRMING SUBSCRIBERS WITHOUT INCREASING CONFIRMATION TIME

摘要

PURPOSE: A subscriber confirmation system and a method thereof are provided to rapidly confirm a subscriber by comparing a front ID with a wildcard ID.;CONSTITUTION: A CSCF(Call Session Control Function) server(100) transmits a distinct ID to an HSS(Home Subscriber Server)(200). When a virtual DB(DataBase)(250) does not include subscriber information which is not matched with the received distinct ID, the HSS generates a front ID. When a subscriber DB includes information matched with the front ID, the HSS deletes a regular expression divider from a wildcard ID by using a regular expression pattern matching function.;COPYRIGHT KIPO 2013;[Reference numerals] (250) Subscriber DB; (S100,S400) Transmitting a DISTINCT ID; (S200) Searching the DISTINCT ID in the subscriber DB; (S300) Generating a FRONT ID if failure(deleting a last digit from initial FRONT ID = DISTINCT ID)(deleting a last digit from FRONT ID = previous FRONT ID); (S500) Is the searching succeeded?; (S600) Confirming whether the DISTINCT ID is included in a WILDCARD ID by deleting a regular expression from the WILDCARD ID and using a regular expression pattern match function;
