Logical Address Assignment in Cloud Cell Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a cloud cell environment, mobile stations face increased complexity in managing multiple logical addresses for communication with multiple base stations, leading to delayed data and control packet processing, which is undesirable in high-speed networks.
Innovation Solution
A method and apparatus for assigning a unique logical address to a mobile station using a disjoint address space, where a master base station selects and assigns a logical address from a subset of a common address space, allowing the mobile station and multiple base stations to communicate effectively within the cloud cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple logical addresses are assigned to mobile stations in cloud cell for communication with multiple base stations, then communication coverage and connectivity are improved, but device complexity and processing delay increase
Solution Approach 1:
The patent merges multiple logical addresses into a single common logical address that is reused across multiple base stations. Instead of assigning unique logical addresses to each base station-mobile station pair, the system uses a single common logical address that remains consistent regardless of which base station in the cloud cell the mobile station connects to, thereby reducing mobile station complexity while maintaining communication coverage.
Solution Approach 2:
The common logical address serves multiple functions across different base stations. A single logical address is used universally for identification and addressing purposes when the mobile station communicates with any of the multiple base stations in the cloud cell, eliminating the need for multiple address management mechanisms at the mobile station.
2Adaptability or versatility
If multiple logical addresses are maintained by mobile station for different base stations, then network connectivity is improved, but packet processing time increases
Solution Approach 1:
The patent combines multiple address management tasks into a single common logical address that does not change based on the serving base station. This merging eliminates the need for the mobile station to determine which logical address to use when connecting to different base stations, thereby reducing packet processing time while maintaining network connectivity.
Solution Approach 2:
The system pre-establishes that a single common logical address will be used across all base stations in the cloud cell, eliminating the need for real-time address selection or determination when the mobile station connects to different base stations, thus reducing processing delay.
3Measurement precision
If unique logical addresses are assigned by each base station to mobile stations, then address uniqueness and identification accuracy are improved, but system complexity and management overhead increase
Solution Approach 1:
The patent merges the address assignment functions of multiple base stations into a unified common logical address system. Instead of each base station independently assigning unique addresses, the system uses a single common logical address that provides sufficient uniqueness and identification accuracy across the entire cloud cell, thereby reducing management complexity.
Solution Approach 2:
The system changes the address assignment parameter from base station-specific unique addresses to a cloud cell-wide common logical address. This parameter change maintains address identification accuracy while significantly reducing the complexity of address management and allocation across multiple base stations.

AI summary
A method and a system for assigning a unique logical address to a mobile station in a cloud cell are provided. The method includes selecting, by the master base station, a unique logical address from an associated set of addresses, wherein the set of addresses is a subset of a common address space, and assigning the unique logical address to the mobile station so that the mobile station and each of the plurality of base stations communicate in the cloud cell using the assigned unique logical address.
