SMALL-CAPACITY IMS CORE SYSTEM

摘要

A small-capacity IMS core is a system that provides support so that a group customer using an IMS service can manage a POTS system and an Internet telephone system in parallel and can manage a non-IMS terminal. This system includes a main control unit (MCU) configured to provide only functions that belong to the functions of an MCU IMS structure and that are required for a group customer, a line interface unit (LIU) configured to be used to extend physical ports of the MCU and a POTS, a SIP gateway configured to convert a standard SIP message into an IMS message, and an FMC controller configured to provide support in order to enable a wireless terminal, such as a wireless IMS terminal/smartphone, to be used in a mobile environment. This system includes an IP communication-based virtual Ethernet back-plane so that the units can exchange information at high speed.

1. An IMS core system, comprising:
a main control unit (MCU) configured as a terminal device that uses services while operating in cooperation with an IMS service provider network including an Internet telephony network and an IPTV network, and configured to include an IMS core, including a CSCF, an MGW and an ABGF, and a function of an IMS terminal; and a back-plane configured to detect an Internet speed and a half/full duplex mode for each slot, and to perform exchange of information between units, including the MCU, using a non-blocking method.
