Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In millimeter-wave mobile broadband systems, mobile stations face increased complexity in managing multiple logical addresses for communication with multiple base stations in a cloud cell, leading to delayed data and control packet processing due to the need to determine and configure addresses for each base station.
Innovation Solution
A method and system where a master base station determines and assigns a unique logical address from unassigned address spaces across multiple base stations, allowing the mobile station to communicate with all base stations using a single unicast logical address, reducing the complexity and processing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple base stations assign individual logical addresses to mobile stations in a cloud cell, then each base station can uniquely identify the mobile station, but the mobile station complexity increases and processing delays occur due to managing multiple addresses
Solution Approach 1:
The patent merges the logical address assignment function from multiple base stations into a single master base station. The master base station collects unassigned logical addresses from all slave base stations, selects one, and assigns it to the mobile station. This consolidation eliminates the need for the mobile station to manage multiple logical addresses while maintaining unique identification across all base stations in the cloud cell.
Solution Approach 2:
The master base station acts as an intermediary between the mobile station and multiple slave base stations. It receives unassigned logical addresses from slave base stations, performs the selection process, and assigns the chosen address to the mobile station. This intermediary role centralizes the address management function, reducing mobile station complexity while ensuring reliable identification.
2Adaptability or versatility
If mobile station determines and configures logical addresses for each base station, then communication with multiple base stations is enabled, but data and control packet processing is delayed
Solution Approach 1:
The master base station performs the logical address selection and assignment as a preliminary action before the mobile station needs to communicate with multiple base stations. By pre-determining the unique logical address through coordination with all slave base stations, the system eliminates the need for the mobile station to perform address determination and configuration during packet processing, thereby improving processing efficiency.
3Adaptability or versatility
If each base station maintains separate address spaces, then address allocation flexibility is improved, but the complexity of coordinate unassigned addresses across multiple base stations increases
Solution Approach 1:
The master base station merges the address allocation coordination function by collecting unassigned logical addresses from all slave base stations' address spaces. This consolidation allows the system to maintain the flexibility of separate address spaces while simplifying the coordination process to a single centralized decision-making point.
Solution Approach 2:
The master base station receives feedback about unassigned logical addresses from slave base stations, processes this information, and makes the final address assignment decision. This feedback mechanism enables flexible address allocation across multiple base stations while keeping the coordination complexity manageable through systematic information gathering and processing.

AI summary
A method and system for assigning a unique logical address in a cloud cell having a mobile station, slave base stations and a master base station are provided. The method includes determining at least one unassigned logical address from respective address spaces associated with the slave base stations and the master base station in the cloud cell by the master base station, selecting the unique logical address from the at least one unassigned logical address determined from the respective address spaces associated with the plurality of base stations, and assigning the selected unique logical address to the mobile station in the cloud cell. The mobile station and each of the plurality of base stations communicate in the cloud cell using the assigned unique logical address.
