    • An apparatus and a method for processing a call of an intelligent network service are provided to reduce a service request failure rate by guaranteeing an intelligent network service by using a detour routing route. A soft switch(200) determines whether a received call is a call of an intelligent service, and if the received call is a call of an intelligent service, the soft switch(200) attempts connection to an SCP(Service Control Point) which controls the corresponding intelligent network service. If the connection to the SCP fails, the soft switch(200) obtains a detour route and re-requests the intelligent network service. A database(220) stores a number configuration table having information of an intelligent network service requested by a subscriber, an SCP information table having SCP information for a connection to the corresponding SCP, and a routing table having information for obtaining a detour route by setting a route for call processing.

    • PURPOSE: A dynamic CODEC selecting system for a voice call service in a next generation network media gateway system and a selecting method therefor are provided to observe congested situations of a transfer network while an analog voice call is changed into a packet, and to actively select CODECs according to the observed network situations, thereby reducing congestions. CONSTITUTION: A subscriber interface(110) decides whether a subscriber attempts calling, and identifies call attempt information on a voice call attempt. A subscriber information searcher(120) searches a subscriber DB(150) by using the call attempt information, and decides whether the subscriber uses a variable CODEC. If so, the call attempt information is transmitted to a CODEC selecting device(140). An MEGACO protocol interface(130) receives information on each CODEC transmission rate and the number of transmission bytes as statistical information for recently completed voice calls, and stores the received information. The CODEC selecting device(140) decides network congested situations by using the statistical information and CODEC variable coefficients, and selects a CODEC for a newly set voice call service.
