Mobile Station Clustering for Base Station Disruption Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, when a Base Station (BS) is disrupted due to natural disasters or physical damage, existing technologies fail to provide continuous data communication services to Mobile Stations (MSs), leading to service interruptions until alternative connections are established.
Innovation Solution
The method and apparatus enable Peer-to-Peer (P2P) communication and gateway establishment between Mobile Stations (MSs) to maintain data communication by forming clusters and using dedicated control channels for preamble signals, cluster member lists, and resource allocation, allowing MSs to transmit data directly even when a BS is disrupted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Mobile Stations form clusters and establish Peer-to-Peer communication while a Base Station is disrupted, then service continuity and communication reliability are improved, but device complexity and network management complexity increase
Solution Approach 1:
The network is segmented into autonomous clusters, each managed by a Cluster Head. This segmentation allows local decision-making and cluster management without requiring continuous Base Station control, thereby maintaining service continuity while distributing management complexity across multiple Cluster Heads rather than concentrating it at the Base Station level.
Solution Approach 2:
Clusters are designed to be self-organizing and self-managing entities. Cluster Heads automatically perform functions such as member management, resource allocation, and inter-cluster gateway establishment without requiring Base Station intervention. This self-service capability maintains reliability during disruptions while the standardized self-organization protocols prevent excessive complexity.
2Speed
If Mobile Stations establish direct Peer-to-Peer communication without Base Station, then communication speed and responsiveness are improved, but loss of information and coordination difficulties increase
Solution Approach 1:
The Cluster Head serves as an intermediary for coordination between Mobile Stations within a cluster. It maintains a cluster member list and manages resource allocation, ensuring that coordination information is preserved and distributed appropriately. This intermediary role enables fast direct communication while preventing information loss through centralized cluster-level coordination.
Solution Approach 2:
The system implements feedback mechanisms where Cluster Heads receive status information from Mobile Stations and provide coordination decisions in return. This feedback loop ensures that coordination information flows efficiently within the cluster, maintaining awareness of network state without requiring Base Station involvement, thus preserving both speed and information integrity.
3Adaptability or versatility
If clusters merge to expand coverage area, then service coverage and adaptability are improved, but device complexity and synchronization requirements increase
Solution Approach 1:
Gateway Mobile Stations serve as intermediaries between different clusters, enabling coverage expansion through cluster merging. The Gateway maintains relationships with multiple Cluster Heads and facilitates coordinated communication between clusters. This intermediary mechanism allows adaptive coverage expansion while the Gateway manages synchronization complexity, preventing it from overwhelming individual Mobile Stations.
Solution Approach 2:
Multiple clusters can merge to form larger service areas by combining their coverage zones. The merging process is managed through standardized protocols where Cluster Heads exchange information and coordinate resources. This merging capability improves adaptability and coverage while the standardized protocols keep synchronization complexity manageable through structured interaction patterns.

AI summary
A method provides data communication while a Base Station (BS) is disrupted in a wireless communication system. The method includes, when a plurality of Mobile Stations (MSs) receive a preamble signal from a cluster header through a dedicated control channel while the BS is disrupted, sending a message requesting cluster member subscription to the cluster header, in the cluster header, including the plurality of MSs in a cluster member, configuring a cluster member list, and broadcasting the cluster member list, in a source MS among the plurality of MSs, sending a data transmission request message to the cluster header using the broadcasted cluster member list, in the cluster header, one of unicasting and broadcasting a response message for the data transmission request of the source MS, and, in the source MS, transmitting data to a target MS among the plurality of MSs based on the response message.
