A communication system includes a central cloud server to establish a primary communication path between a radio access network (RAN) node and one or more user equipment (UEs) via a first set of edge devices of a plurality of edge devices, where each edge device is configured as a mesh node of a mesh network. The central cloud server determines a plurality of secondary communication paths between the RAN node and the one or more UEs via different sets of edge devices. The central cloud server ranks each of the plurality of secondary communication paths in terms of one or more signal quality parameters and controls switching from the primary communication path to one or more secondary communication paths configured as backup communication paths within a threshold time to maintain a continuity in service to the one or more UEs for uplink and downlink communication.

A communication system includes a first edge device that obtains timing information at a first time instant from a radio access network (RAN) node or a central cloud server. The timing information is indicative of a unique system frame number or a sub-frame of the unique system frame number that is to be received at the first edge device. The first edge device detects the unique system frame number or the sub-frame of the unique system frame number at a second time instant. The first edge device executes a switching event in which a new communication link is established with a second edge device neighboring the first edge device. The new communication link corresponds to a change triggered in a mesh network to maintain a continuity in uplink and downlink communication between one or more UEs and the RAN node via the mesh network.

A communication system includes a central cloud server that gradually decreases a gain of a currently active path, which corresponds to a primary communication path between a radio access network (RAN) node and one or more user equipment (UEs) via a first set of edge devices of a plurality of edge devices, until the currently active path becomes dormant. The central cloud server then gradually increases a gain of a dormant path, which corresponds to a secondary communication path between the RAN node and the one or more UEs via a second set of edge devices of the plurality of edge devices, until the dormant path becomes a new active path. Further, the central cloud server periodically checks whether the new active path has a signal strength greater than a threshold in order to maintain a continuity in service to the one or more UEs for an uplink and downlink communication.
