Embodiment Construction
[0044] figure 1 A schematic diagram of at least part of an NGN service provisioning system 100 is described, especially an IMS-based service provisioning system for providing services to one or more enterprise networks according to an embodiment of the present invention.
[0045] The system includes one or more NGCNs connected to an IMS platform 106, eg, IP-based enterprise networks 102, 104. The IP-PBXs 108, 110 associated with these enterprise networks are responsible for controlling the endpoints on the enterprise premises and for managing the required services. Endpoints (eg, terminals) 112a, 112b, 114a, 114b used in an enterprise network may include wired and / or wireless phones, SIP phones, and the like.
[0046] The IMS core typically includes a set of Call / Session Control Functions (CSCFs), including a Proxy-CSCF (P-CSCF) 116 , an Interrogating-CSCF (I-CSCF) 118 and a Serving-CSCF (S-CSCF) 120 . Typically, the P-CSCF is the first point of contact within the IMS core a...
