This TR studies the technical requirements for carrier grade inter-operator IP Interconnection of Services for the support of Multimedia services provided by IMS and for legacy voice and video PSTN/PLMN services transported over IP infrastructure (e.g. VoIP). These requirements should take into account the new and developing, convergent interconnect models currently being developed outside 3GPP.
Requirements should fulfil:
Identification of the technical requirements for IP Service Interconnection (service control and user plane aspects) between Service Providers.
Identification of requirements for the Stage 2 and 3 work to identify relevant existing specifications, initiate enhancements and the development of the new specifications as necessary.
Supporting of IP Service Interconnection models as defined by other bodies (e.g. GSMA, ETSI, ITU‑T).
