摘要

PURPOSE: A number portability call processing system is provided to efficiently process number portability calls without increasing a load on an SSW(Soft Switch).;CONSTITUTION: A number portability call processing system includes first and second number portability call processing parts(100,200), an SSW(300), and a number portability database(400). The number portability database stores number porting information of a subscriber. The first number portability call processing part processes number portability calls with an ACQ(All Call Query) method by referring to the number portability database. The second number portability call processing part processes number portability calls with a QoR(Query on Release) method by referring to the number portability database. The SSW is connected to the first and second number portability call processing parts and routes the calls processed by the first and second number portability call processing parts.;COPYRIGHT KIPO 2013;[Reference numerals] (100) ACQ processing unit; (200) QoR processing unit
