The CSCF may perform basic functions for session initiation protocol (SIP) based multimedia session control such as subscriber registration, authentication, service triggering, routing, various call control, and address handling.

The P-CSCF 111 is the first point where the terminal accesses the IMS. The P-CSCF 111 may exist in a home network or a visited network. In some networks, this can be used as a session border controller.

The I-CSCF 112 serves as a contact point for incoming calls to connect to subscriber stations in the entire network and as a contact point with terminals of other network subscribers roaming in the network. The I-CSCF 112 is located at the border of the management domain when no border function is present. Thus, the IP address is published in the DNS of the domain so that it can be found by servers in other domains and used as input nodes of the network. I-CSCF 112 queries the HSS for the location of the user using DIAMETER (Cx, Dx interface) and forwards the SIP message to S-CSCF 112 to which the user is assigned.

The S-CSCF 112 performs session control as a SIP server as a central node of the signaling layer. It always exists in the home network and uses DIAMETER (Cx, Dx interface) to download and upload user profiles from HSS 115.

The BGCF 114 is an interface that interconnects IMS with an existing network.

The Home Subscriber Server (HSS 115) is a master database of subscribers that stores and manages subscriber profile, authentication and location related data, and which the I-CSCF 112 or S-CSCF 112 requires. Information can be provided. In addition, the HSS 115 may generate an authentication vector required for subscriber authentication, and may include a function of a home location register (HLR). The HSS 115 includes user related subscription information related to multimedia session control, that is, user location information, security information for authentication and permission of the user, and user profile information including a service subscribed to by the user.

The media resource function (MRF) may include a media resource function controller (MRFC 116) and a media resource function processor (MRFP 117).

MRF provides media sources for announcement broadcast operations (voice and video), media conferencing (voice stream mixing), text-to-speech and voice recognition and real-time transcoding of multimedia data (to different codecs).

The MRFC 116 controls the MRFP 117 via the H.248 interface to the SIP user agent signal layer node for the S-CSCF 112.

The MRFP 117 implements all media related functions as media layer nodes.
