Decoupled Radio Resource Manager for Access Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IP network architectures require separate modules for each access technology, making them non-portable and necessitating undesirable changes when new radio technologies are introduced, limiting scalability and flexibility.
Innovation Solution
A decoupled radio resource manager is implemented, allowing the access gateway to manage radio transmission characteristics independently of specific access technologies, eliminating the need for technology-specific modules and enabling seamless integration of various radio technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate modules are installed for each access technology in the access gateway, then each technology can be managed independently, but the device complexity increases and portability decreases
Solution Approach 1:
The radio resource management functions are extracted from the access gateway and placed in a separate radio network controller. This separation removes the technology-specific modules from the access gateway, reducing its complexity while maintaining the ability to support multiple access technologies through the centralized RRC.
Solution Approach 2:
The radio network controller is designed to handle multiple access technologies (CDMA, WiFi, WiMAX, GSM) through a single unified structure. Instead of requiring separate modules in the access gateway for each technology, the universal RRC provides centralized management for all technologies.
2Reliability
If the access gateway is configured with technology-specific modules, then radio resource management is precise for each technology, but changes require installation of new modules reducing ease of operation
Solution Approach 1:
By extracting the radio resource management functionality from the access gateway and placing it in the radio network controller, the system maintains precise radio resource management while enabling easier network changes. The RRC can be updated or reconfigured without modifying the access gateway infrastructure.
Solution Approach 2:
The system allows dynamic reconfiguration of radio resource management functions in the RRC without requiring physical changes to the access gateway. This enables flexible adaptation to new technologies or requirements through software or configuration changes rather than hardware modifications.
3Adaptability or versatility
If independent modules are used for each access technology in the access gateway, then each technology can be optimized independently, but upgrade costs increase
Solution Approach 1:
Extracting the radio resource management functions from the access gateway consolidates them in the RRC, reducing the need for multiple independent modules in the gateway. This lowers upgrade costs since changes are made centrally in the RRC rather than requiring modifications to multiple gateway modules.
Solution Approach 2:
The system merges the radio resource management functionality for all access technologies into a single RRC entity. This consolidation reduces the overall system complexity and lowers upgrade costs by eliminating the need to maintain and update separate modules for each technology in the access gateway.
Data Source
AI summary
Particular embodiments provide an access gateway that facilitates communication between a plurality of access technologies. The access gateway facilitates data communication with an access terminal through a bearer path. A radio resource manager is configured to provide radio resource management functions for the communications. The radio resource manager is decoupled from the bearer path and provides control of radio transmission characteristics for the bearer path to the gateway. Because the radio resource manager is not in the bearer path, the access gateway may be access technology agnostic. Thus, the access gateway does not need to have access-specific modules based on the radio technology for each bearer path.
