Advanced requirements for IP interconnect
This document 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 & 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).
