ITU-T Q.5005 PDF

This Recommendation specifies requirements, framework, interfaces (IFs) and protocols for signalling network analysis and optimization in an IMT-2020 network. The signalling network in IMT-2020 is the totality of network functions and corresponding signalling exchanges that are related to IMT-2020 service procedures. The IMT-2020 signalling network analysis and optimization system is a network management system that consists of components for signalling collection, signalling network analysis, signalling network optimization and artificial intelligence or machine learning (AI/ML) assistance. The IMT-2020 signalling network analysis and optimization system is designed with the characteristics of high efficiency, real time reaction, reliability and intelligence, aimed at application in an IMT-2020 network.

The following aspects of IMT-2020 signalling network analysis and optimization system are addressed in this Recommendation.

• Overview, which presents the main network entities and IFs that are used in IMT-2020 signalling network analysis and optimization systems.

• Requirements for IMT-2020 signalling network analysis and optimization, including general signalling requirements for collection, network analysis and network optimization.

• A framework for IMT-2020 signalling network analysis and optimization systems, including global view, system architecture, external boundary and component design of signalling network analysis and optimization systems.

• IFs and protocols of IMT-2020 signalling network analysis and optimization systems, including internal IFs, external IFs and corresponding protocols.

• Service procedures of signalling interworking between collection, network analysis and network optimization.

• Functions of IMT-2020 signalling network analysis and optimization systems that are provided by an internal AI assistance component or external AI platforms. The architectural framework for an external AI platform is specified in [ITU-T Y.3172].

• Security considerations of IMT-2020 signalling network analysis and optimization systems, including signalling collection security, signalling network analysis security, signalling network optimization security, AI/ML-related security, inter-working security, data transport security and user privacy.
