ETSI ETSI TR 103 404 V1.1.1 (2016-10) 6 1 Scope The present document aims at providing recommendations for the introduction of autonomic

25、s (management and control intelligence) in the 3GPP Core and Backhaul network architectures. To this effect, it covers the instantiation of the reference model for Autonomic Networking, Cognition and Self-Management, called GANA (Generic Autonomic Networking Architecture), onto the architecture defi

26、ned in ETSI TS 123 401 i.2 and ETSI TS 123 402 i.35. It superimposes GANA Decision Elements (DEs) into node/device architectures and the overall 3GPP network architecture, so that the DEs and their associated Control-Loops can be further designed to perform autonomic management and control of the sp

27、ecific resources (Managed Entities) in the target architecture. It develops recommendations on the basic behaviours of the GANA Functional Blocks (FBs) in the above context. 3GPP specifications on policy control (ETSI TS 123 203 i.3) and network management (TS 123 32x series) are taken into account

28、into the working reference architecture. It also involves the backhaul network and associated interactions between the different entities for an optimization with an end-to-end perspective. 2 References 2.1 Normative references Normative references are not applicable in the present document. 2.2 Inf
