beyond 5G systems

Information and Communications Technology, Japan)

To seamlessly cover urban and rural areas, mountains and deserts, as well as sea and air, with
high quality ubiquitous communication services, the convergence of Terrestrial Networks (TNs)
and Non-Terrestrial Networks (NTNs) such as satellites is essential in beyond 5G communication
systems. This paper presents the scenarios and architectures of integrated and individual network
control systems for TN and NTN convergence in the control plane. The integrated network
control system enables end-to-end service design, orchestration, performance monitoring,
closed-loop control, and automation. It promotes interoperability in the control plane of TN and
NTN domains composed of virtualization-supporting infrastructures and possibly managed by
different organizations. This paper is related to ITU-T Study Group 13's activities of
standardizing fixed, mobile and satellite convergence technologies.
S1.2 Towards computing and network convergence: QoE-oriented service anycast based on SRv6

Technology Co., Ltd., China)

The new mobile Internet services represented by extended Reality (XR) have brought new
challenges to computing and networks. A new generation of Information and Communication
Technology (ICT) infrastructure with both computing and communication capabilities is being
promoted. Traditional load balancing technologies cannot sense the connection between users
and services. It is also difficult to support large-scale distributed computing service instances, so
the service experience provided can be poor.

In this paper a service anycast system based on a Segment Routing over IPv6 (SRv6) data plane
is proposed, which can provide a Quality of Experience (QoE)-oriented load balancing capability
for the network according to the obtained status information of network and computing service
instances. Besides, an IP address identification mechanism is also proposed to help the control
plane handle traffic engineering policies, and to support efficient service resource discovery,
seamless mobility, and service continuity.

S1.3 Towards a more flexible networking landscape

Technological advancements leading to 5th generation networks mainly focused on improving
coverage and performance in terms of bandwidth and latency. While these will likely remain
aspects of continuous improvement, along with issues on reliability and security, this paper
argues that flexibility is a key property that 6G networks should exhibit in order to overcome
important limitations of the current networking landscape and fulfill emerging user needs and
application requirements. We identify key areas that can contribute towards more flexibility,
present existing efforts on relevant technologies and discuss the research challenges that need to
be addressed in order to reach the desired level of flexibility.
