Universal Mobile Telecommunications System (UMTS); LTE; All-IP network (AIPN) feasibility study
|Publication Date:||1 August 2020|
The present document studies the feasibility of the progression of the 3GPP system to an AIPN. More specifically, this document:
a) Identifies and describes the objectives and user, business and technological drivers for progression of the 3GPP system to an AIPN:
i) Investigates the High Level Objectives
ii) Investigates Motivations and Drivers
iii) Investigates impacts upon current models (e.g. business/charging/se
b) Defines and develops the end-user and AIPN operator aspects of an AIPN:
i) Produces an AIPN vision, taking into account the special requirements for the mobile community e.g. carrier grade, optimisation for the radio environment, recognizing support of multiple access system scenarios.
ii) Investigates needs and requirements associated with the evolution of the 3GPP System to an AIPN.
iii) Investigates requirements associated with the reuse of legacy infrastructure and support of legacy terminals
iv) Investigates migration and cost effective introduction of new technology.
c) Identifies the capability expansion required to introduce the AIPN concept into the 3GPP system (migration and co-existence)
d) Evaluates whether an AIPN should be standardised within 3GPP, and in the case of a positive conclusion identifies the subsequent steps to be taken to achieve this by defining the scope, target, and roadmap for work to be undertaken within Rel-7 and future 3GPP releases.
