Wireless Resource Override Mechanism for Overloaded Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for overriding a mobile terminal's selected resource in wireless communications systems, such as E-DCH, are limited to 32 resources and inefficiently manage resource allocation, particularly in overloaded cells where more resources are needed.
Innovation Solution
A method and apparatus that allow a network device to override a selected resource request and provide alternative resources without introducing new signaling, enabling the mobile terminal to select from multiple sets of resources associated with different scrambling codes, thereby avoiding restrictions on the number of resources available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the network provides up to 32 resources to mobile terminals using traditional override methods, then resource allocation is manageable, but the total number of available resources is restricted to 32 resources
Solution Approach 1:
The patent divides the resource pool into multiple sets of resources, where each set contains up to 32 resources. Instead of providing a single flat list of 32 resources, the network now provides multiple segmented sets (e.g., first set, second set, third set), each identifiable by a set identifier. This segmentation allows the system to overcome the 32-resource limitation while maintaining manageable allocation through set-based identification.
Solution Approach 2:
The patent introduces a new dimension to resource identification by adding set identifiers alongside resource identifiers. Previously, resources were identified by a single index (0-31). Now, resources are identified by a combination of set identifier and resource identifier within the set, creating a two-dimensional resource addressing space that exponentially increases the total number of available resources.
2Quantity of substance
If multiple sets of resources are provided to mobile terminals, then more than 32 resources become available, but the complexity of resource management increases
Solution Approach 1:
The patent introduces set identifiers as an intermediary layer between the network and mobile terminals. Instead of directly managing individual resource indices across multiple sets, the system uses set identifiers to group and organize resources. This intermediary abstraction simplifies the management complexity by providing a hierarchical structure where sets can be independently configured and managed.
Solution Approach 2:
The patent performs preliminary organization of resources into sets with assigned set identifiers before allocation to mobile terminals. The network pre-configures multiple sets of resources, each with its own identifier, and makes these sets available to mobile terminals. This preliminary structuring reduces the complexity of real-time resource management during actual allocation operations.

AI summary
A method, apparatus and computer program product are provided for overriding requests for a selected communication resource and indicating a different resource(s) for communication. A method and apparatus may select a communication channel resource type associated with a first set of resources based in part on determining that a predetermined condition is met and may provide a message, to a network device, requesting usage of the selected communication channel resource type. The method and apparatus may also receive a response, from the network device, denying the request for the selected communication channel resource type. The method and apparatus may also cause selection of another communication channel resource type associated with a second set of resources and providing a generated request to the network device requesting usage of the second type of communication channel resource type.
