Fixed, mobile and satellite convergence
|
| Description:
|
1 Motivation
The usages of different access technologies provide users with different user experiences, such as high bandwidth, low latency, massive connections, high reliability, and high security. Fixed, mobile and satellite convergence (FMSC) is the capability that provides services and applications to end users regardless of the fixed, mobile or satellite access technologies being used. The main purpose of FMSC for multi-access network is to utilize 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. Users and operators benefit from FMSC in the aspects of seamless connection, mobility enhancements, communications reliability, service continuity, network robustness, network efficiency, energy efficiency, etc.
Fixed, mobile and satellite convergence is envisioned as a major direction of evolution for non-radio aspects of IMT-2020 and IMT‑2030 networks. In FMSC network, the land-based or satellite-based core network connects to the fixed access network, mobile access network, and satellite access network; and includes the core network functionalities and FMSC functionalities. This Question focuses on the standardization of requirements, framework, network capabilities, enabling technologies, network function enhancements, and service enhancements to support FMSC in the context of non-radio aspects of IMT‑2020 and IMT-2030 networks, ensuring a consistent user experience for the target of ubiquitous connectivity for various types of user equipment. The subjects on fixed mobile convergence (FMC) in IMT-2020 and IMT-2030 networks 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:
