1Area of stationary object
If front-haul communication links are used to distribute communication services in WDS networks, then communication coverage and service distribution capability are improved, but link failures occur that disrupt communication services
Solution Approach 1:
The system pre-establishes multiple front-haul communication links between the central DRU and remote DRUs, including both primary and secondary links. This preliminary setup of redundant communication paths enables the system to maintain service continuity when link failures occur, as alternative paths are already in place and configured.
Solution Approach 2:
The system dynamically changes communication parameters by switching from primary to secondary front-haul links when failures are detected. The control circuit monitors link status and adjusts the active communication path based on real-time conditions, changing the operational state from normal transmission to failover mode to maintain service continuity.
2Reliability
If communication services are rerouted to operational links after failures, then service continuity is improved, but bandwidth capacity requirements may not be met
Solution Approach 1:
The control circuit continuously monitors the status of front-haul communication links and the bandwidth utilization of operational links. When a failure occurs, the system uses this feedback information to identify suitable secondary links that have both available capacity and sufficient bandwidth to accommodate the rerouted services, ensuring both continuity and quality of service.
Solution Approach 2:
The system dynamically adjusts the routing of communication services based on real-time link status and bandwidth availability. Rather than using static routing, the system adapts its path selection to current conditions, allocating bandwidth resources flexibly to meet the requirements of rerouted services while optimizing the use of available capacity in operational links.
3Reliability
If multiple front-haul communication links are established for redundancy, then service continuity is improved, but system complexity increases
Solution Approach 1:
The control circuit acts as an intermediary that manages the complexity of multiple front-haul links. It automatically monitors link status, detects failures, and performs rerouting operations without requiring complex manual configuration or intervention. This centralized control mechanism simplifies the management of redundant links by automating the complexity-handling functions.
Solution Approach 2:
The system performs self-diagnosis and self-recovery by automatically detecting link failures and rerouting services without external intervention. The control circuit continuously monitors the health of communication links and autonomously activates backup paths when needed, enabling the system to manage its own complexity and maintain service continuity without requiring complex external control mechanisms.

AI summary
Embodiments of the disclosure relate to a front-haul communications system for enabling communication service continuity in a wireless distribution system (WDS) network. A WDS network includes a front-haul communications system and a plurality of remote WDSs. In this regard, a front-haul link control circuit is provided in the front-haul communications system to detect failed front-haul communication link(s). In response to detecting the failed front-haul communication link(s), the front-haul link control circuit reroutes a disrupted communication service(s) to operational front-haul communication link(s) based on bandwidth capacity requirements of the disrupted communication service(s) and unused bandwidth capacity of the operational front-haul communication link(s). By detecting the failed front-haul communication link(s) and rerouting the disrupted communication service(s) communicated on the failed front-haul communication link(s), it is possible to enable communication service continuity in the WDS network, thus enhancing efficiency and performance of the WDS network.
