Disaster Resistance Mesh Radio Access Network Method

Abstract

The invention relates to a method that provides uninterrupted communication in the event of a possible disaster, such as a collapse of the terrestrial network, power outage, capacity shortage due to high traffic, when the transmission infrastructure becomes unusable, when access to the core network (7) cannot be provided through base stations (4) in the areas where the user device (1) is cut off and the emergency communication requirement cannot be met.

Description

1 TARIFF Disaster Resistance Mesh Radio Access Network Method Technical Area The invention relates to 6G mobile communication systems, NTN (non-terrestrial network). (network), satellite communication and TN (terrestrial-cellular radio access network) in case of disaster 5 A communication system in a self-healing mesh topology that provides uninterrupted communication. the aim is to ensure the stability of the network, especially the terrestrial network, in disaster situations such as earthquakes. uninterrupted communication in case it becomes partially or completely unusable It relates to a method aimed at achieving this. State of the Art 10 Today, existing mobile communication networks are fundamentally entirely terrestrial in terms of user experience. device, base station (gNB - Next Generation NodeB), fiber from backhaul (fiber transport) and core network components This is how NTN systems are formed. Today, they are used as an alternative to backhaul, for rural coverage, or for IoT. It is used for Internet of Things (IoT) services. These two approaches are 15 The main problems during a disaster are:  In the event that terrestrial transport, i.e., fiber infrastructure, is damaged during a disaster, the base Even if the station remains intact, access to the core grid may be lost.  Existing satellite systems are not fully integrated with the core network. Direct mobile There are various limitations, such as terminal support for access. 20  Due to the single-point dependent architecture, a single gathering point may become inactive during a disaster. If it falls outside the designated area, service may not be available over a wide area.  Emergency, location reporting, disaster relief and law enforcement across all networks The traffic of these forces may not be prioritized or guaranteed. This Therefore, interruptions and restrictions in emergency communication during a disaster occur. 25 It is possible. In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made. 2 Purpose of the Invention The invention was created by drawing inspiration from existing situations and overcoming the aforementioned drawbacks. It aims to solve the problem. The purpose of the invention is to address the potential disasters that may occur at base stations on existing terrestrial networks. damage to the fiber transport infrastructure, loss of access to the aggregation points 5 regionally due to loss and high utilization resulting from heavy emergency traffic. Problems such as loss of communication mean that NTN satellites and ground base stations are not equal. The solution is to eliminate access nodes by having them work in a mesh architecture. In the system covered by the invention, satellites are not only backhaul stations, but also base stations. They don't just act as access points. On the contrary, all nodes are mesh radio 10s. They function like routers. This allows them to support the fiber transmission infrastructure or a specific base station. In situations where stations are unusable due to disasters, mobile users can use 6G NTN mesh. They can access the core network via this. To achieve the objectives described above, in the event of a potential disaster, terrestrial Network collapse, power outage, capacity shortage due to high traffic 15 In situations where the transmission infrastructure becomes unusable, the user In areas where the device's access is interrupted, it connects to the core network via base stations. When access is unavailable and emergency communication needs cannot be met, uninterrupted A method for communication has been developed, and the method in question is: - In a mesh-structured network architecture, the user device's communication request is 20 If present, network controller and disaster mode management system By monitoring disaster situations and traffic density, necessary traffic measures are taken. guidance to be provided, that communication is provided via satellite, and the traffic is routed through satellite ground station 25 and in upstream transmission as well traffic is provided via satellite ground station and communication is provided via satellite, or, a suitable base station that can be prioritized for that routing If present, user traffic and signaling will be 30% of the current level. transporting it to the core network via terrestrial fiber transmission line and 3 For upstream transmission, it is again a fiber transmission line and a base station. communication through It includes the steps involved in the process.
