Telecommunications Resource Redirection via Self-Service Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing common radio resource management (CRRM) methods in heterogeneous cellular networks are limited in distributing traffic across different radio access systems according to a predefined profile, especially during normal operating conditions, and often require knowledge of the current load status of all supported systems, which can be undesirable and may worsen critical load conditions.
Innovation Solution
A method that redirects service requests from a source system to a target system based on past redirection attempts' success or failure, without needing direct knowledge of the target system's load status, simplifying implementation and avoiding critical load worsening by making optimized decisions based on observable feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If CRRM methods use knowledge of current load status of all supported systems to distribute traffic, then traffic distribution according to predefined profile is improved, but system complexity and information requirements increase
Solution Approach 1:
The source system autonomously learns the load status of target systems by observing whether redirection attempts succeed or fail, without requiring target systems to provide load information. This self-service mechanism eliminates complex inter-system communication infrastructure while achieving effective traffic distribution.
Solution Approach 2:
The source system uses feedback from redirection attempt outcomes (success/failure) to dynamically adjust its traffic distribution decisions. This feedback loop enables the system to adapt to changing load conditions without requiring direct knowledge of target system states, resolving the contradiction between effective distribution and system complexity.
2Productivity
If CRRM methods require knowledge of target system load status, then optimized traffic routing is achieved, but target system load may worsen due to additional signaling overhead
Solution Approach 1:
The source system independently determines target system load status through observation of redirection outcomes, eliminating the need for target systems to send load status signals. This self-service approach achieves optimized routing while avoiding additional signaling overhead that would worsen target system load.
3Productivity
If CRRM methods implement complex adaptations across network controllers, then traffic distribution control is improved, but implementation complexity and modification requirements increase
Solution Approach 1:
The source system autonomously learns and adapts to target system characteristics by observing redirection outcomes, eliminating the need for complex adaptations in target system controllers. This self-service learning mechanism achieves effective traffic distribution control while keeping implementation simple and avoiding modifications to target systems.
Solution Approach 2:
The invention separates the learning and adaptation functions to the source system only, while target systems remain unchanged. This segmentation allows complex control intelligence to be concentrated where it is most beneficial, simplifying overall implementation by requiring modifications in only one type of network controller.

AI summary
A method of providing, in a telecommunications network including at least a first and a second set of communication resources, a service to users in a condition of being provided said service both by means of the first set of communication resources and by means of the second set of communication resources. The method includes the steps of: upon receipt, through the first set of communication resources, of a service request related to the service from a user, attempting redirecting the service request to the second set of communication resources; and if the attempt succeeds, provisioning the service to the user by means of the second set of communication resources. The attempt to redirect the service request includes identifying a communication resource among the second set of communication resources, by either considering or not communication resources of the second set as candidates for the service request redirection based on a history criterion that takes into account an observation of the outcome of past redirection attempts.
