The embodiments of the present invention relate to a small-capacity IMS core system which can be applied to a group client. The above-mentioned present invention relates to a system for supporting a group client so as to enable the group client (businesses, institutions, schools, and the like) using an IMS service of a small-capacity IMS core to internally operate both a plain old telephone service (POTS) system and an Internet telephone system, and to use a non-IMS terminal such as a wired/wireless IP telephone, a smartphone, or the like, with an IMS terminal, the system, comprising: a main control unit (MCU) for simply providing only functions necessary for the group client, among each function of an IMS structure; a PSTN processing unit (line interface unit (LIU)) used for extending a physical port of a POTS; a SIP gateway for converting a standard SIP message into an IMS message; and an FMC controller for supporting a wireless terminal such that the wireless terminal such as a wireless IMS terminal/smart phone and the like can be used in a mobile environment. The system includes an IP communication-based virtual Ethernet backplane so as to enable each unit to exchange information at high speeds. |
