Current usages of different access technologies provide users with different user experiences, such as broad bandwidth, low time delay, massive connections, and high security. The main purpose of fixed, mobile and satellite convergence for multi-access network is to federate all means of access technologies including fixed, mobile and satellite accesses, providing users with the capability to access the network ubiquitously and enjoy the best service experience under the circumstance. Users and operators benefit from network convergence of fixed, mobile and satellite, in the aspects of seamless service, connection reliability, service continuity, network efficiency, load balancing, disaster recovery, etc.

In some use cases of networks beyond IMT2020, fixed access network, mobile access network, and satellite access network interwork to form a converged network. A converged access-agnostic core network, which integrates fixed, mobile and satellite core network, also assisted by AI/ML and other innovative technologies, is envisioned as a direction of evolution of networks beyond IMT2020. Therefore, this Question focuses on the study of requirements, use cases, network capabilities, innovative technologies, and service enhancements to support fixed, mobile and satellite convergence, ensuring a seamless user experience within the fixed, mobile and satellite domains for the target of full connectivity for various types of user equipment. Subjects on fixed mobile convergence in networks beyond IMT2020 without satellite access are also in the scope of this Question. The following major Recommendations, in force at the time of approval of this
Question, fall under its responsibility:
