Enhanced Coverage Authorization Mechanism for Wireless Resource Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular systems lack efficient mechanisms for network operators to control and restrict access to enhanced coverage features, leading to unnecessary resource consumption and unauthorized use of enhanced cell coverage by wireless devices.
Innovation Solution
A method and system for authorizing utilization of enhanced coverage, which involves receiving a message indicating a wireless device's support for enhanced coverage features, obtaining its identification, and determining authorization status, allowing or denying access to these features based on subscription and resource constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If enhanced coverage features are made available to all wireless devices, then coverage range is extended, but radio resource consumption increases substantially
Solution Approach 1:
The patent applies local quality by differentiating access rights to enhanced coverage features based on device location and authorization status. Authorized devices receive enhanced coverage resources in EC areas, while unauthorized devices are restricted to normal coverage resources, thereby localizing resource allocation to where it is most needed and preventing wasteful consumption.
Solution Approach 2:
The patent changes the authorization parameter to control access to enhanced coverage features. By introducing an authorization flag that can be set or cleared based on device credentials or network policies, the system dynamically adjusts resource allocation parameters to match actual needs, preventing unauthorized devices from consuming excessive radio resources.
2Adaptability or versatility
If enhanced coverage features are provided without access control, then service availability is improved, but unauthorized use of resources occurs
Solution Approach 1:
The patent implements preliminary action by establishing an authorization check mechanism before allowing access to enhanced coverage features. The network node verifies device authorization status in advance (through subscription data or capability indicators) and pre-configures resource allocation accordingly, preventing unauthorized devices from attempting to use EC resources in the first place.
Solution Approach 2:
The patent introduces an intermediary authorization mechanism between the device and enhanced coverage resources. The network node acts as a mediator that intercepts access requests, verifies authorization status, and either grants or denies access to EC features, thereby protecting resources from unauthorized use while maintaining service availability for legitimate devices.
3Productivity
If access to enhanced coverage is restricted by authorization checks, then resource management is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by integrating the authorization check functionality into existing network node operations. The same network node that manages radio resources and handles device connections also performs authorization verification, eliminating the need for separate complex authorization infrastructure and reusing existing signaling pathways for capability indication.
Solution Approach 2:
The patent implements self-service by enabling devices to self-identify their authorization status through existing capability indication mechanisms. Devices that support enhanced coverage features voluntarily indicate this capability in their signaling, allowing the network to automatically differentiate and allocate resources appropriately without requiring complex active verification protocols.
4Area of stationary object
If unauthorized devices are allowed to camp in EC areas, then coverage area is maximized, but repeated access attempts consume resources
Solution Approach 1:
The patent applies preliminary anti-action by implementing a mechanism that prevents unauthorized devices from successfully accessing EC resources before they can initiate repeated access attempts. The network node monitors for capability indications and immediately restricts EC resource allocation for unauthorized devices, stopping the cycle of repeated access attempts at their source.
