Introduction The 3GPP system currently supports GERAN and UTRAN based Access Networks in conjuncti

43、on with Circuit-Switched and Packet-Switched Core Network domains and IP Multimedia CN subsystem. The All-IP concept was initially introduced within 3GPP in Rel-4 with the standardisation of the MSC Server - MGW split core network architecture for the CS domain and extended from Rel-5 by the standar

44、disation of the IP Multimedia CN sub-system. WLAN as an alternative access system to access services of the mobile core network is recognized from Rel-6 onwards. In order for the 3GPP system to cope with the rapid growth in IP data traffic, the packet-switched technology utilised within 3G mobile ne

45、tworks requires further enhancement. A continued evolution and optimisation of the system concept is also necessary in order to maintain a competitive edge in terms of both performance and cost. It is anticipated that the progression towards an All-IP Network (AIPN) may enable leverage of informatio

46、n technology (IT) hardware and software with general-purpose, and mobile network specific software that should provide cost reduction (CAPEX and OPEX) for infrastructure equipment and applications of 3GPP based mobile networks. Moreover, it is important to ensure compliance with Internet protocols w

47、ithin future developments of the 3GPP system. Additionally, the following aspects identified within TR 21.902 Evolution of 3GPP System 2 are considered relevant to the long-term evolution of the 3GPP system: - A seamless integrated network comprising a variety of networking access systems connected

48、to a common IP based network supported by a centralised mobility manager - A similarity of services and applications across the different systems is beneficial to users - 3GPP should focus on the inter-working between 3GPP Mobile Networks and other Networks considering mobility, high security, charg

49、ing and QoS management Taking the above into consideration it is necessary to further define the All-IP Network (AIPN) concept, explore user, business and technological drivers and evaluate the feasibility of evolving the 3GPP system towards an All-IP Network (AIPN). Furthermore, aspects of the 3GPP system requiring enhancement need to be identified and developed in accordance with this common vision. ETSI ETSI TR 122 978 V13.0.0 (2016-01)73GPP TR 22.978 version 13.0.0 Release 13This report discusses the concept of an “All-IP“ network. In the context of this report the t
