Base Station Service-Differentiated SCell Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio access networks (RANs) lack base-station level awareness of application-specific or service-specific traffic, making it impossible to dynamically allocate resources based on varying application requirements.
Innovation Solution
The method involves a base station receiving service information corresponding to specific traffic for a user equipment (UE), allowing it to determine actions regarding Secondary Cells (SCells), such as activation, deactivation, or modification, to optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If base station receives and processes service information from multiple sources, then service-differentiated resource allocation is achieved, but base station complexity increases
Solution Approach 1:
The patent segments the resource allocation process by creating separate handling paths for different service types (e.g., eMBB, URLLC, mMTC). The base station divides incoming service information processing into service-specific handling routines, allowing each service type to be managed independently according to its requirements, thus achieving service differentiation without overwhelming the base station with monolithic complexity.
Solution Approach 2:
The patent implements preliminary action by pre-configuring service information parameters and resource allocation rules in the base station before actual service delivery. Service characteristics, QoS requirements, and resource allocation policies are prepared in advance, enabling the base station to quickly respond to service information without performing complex real-time analysis for each service request.
2Productivity
If RAN implements Carrier Aggregation with SCell activation, then network capacity increases, but unnecessary resource allocation occurs without service awareness
Solution Approach 1:
The patent applies local quality by making SCell activation decisions specific to each service type and UE scenario. Instead of blanket SCell activation for all UEs, the base station evaluates service information (e.g., traffic type, QoS requirements) and activates SCells only when appropriate for the specific service, ensuring resources are allocated with the right quality and specificity to actual needs.
Solution Approach 2:
The patent implements dynamics by making SCell activation and deactivation decisions dynamic based on real-time service information. The base station continuously monitors service characteristics and adjusts SCell configuration accordingly - activating SCells when service requirements demand additional capacity and deactivating them when services are completed or requirements change, thus optimizing capacity while avoiding unnecessary resource consumption.
3Productivity
If base station makes real-time SCell activation decisions, then resource allocation efficiency improves, but processing time increases
Solution Approach 1:
The patent resolves this contradiction by performing preliminary action - pre-configuring service information parameters, QoS thresholds, and resource allocation rules in the base station before actual service delivery. This advance preparation enables the base station to make rapid SCell activation decisions based on pre-established criteria rather than performing complex real-time analysis, thus maintaining high resource allocation efficiency while minimizing processing time.
Solution Approach 2:
The patent applies parameter changes by establishing predefined thresholds and parameters for service information evaluation. The base station uses these pre-set parameters to quickly determine whether SCell activation is needed, transforming complex decision-making into parameter-comparison operations that are computationally efficient and time-sensitive, thereby achieving both high efficiency and low processing time.

AI summary
A novel method for service based network resource allocation is disclosed. In one embodiment, a method is disclosed comprising receiving from a UE at a base station over a Primary Cell (PCell), a request message to perform an action with respect to a Secondary Cell (SCell), the request message including service information. The method then determines a specific action to be performed with respect to the SCell based on the service information. Finally, the method performs the specific action with respect to the SCell at the base station and transmits a connection reconfiguration message to the UE to direct the UE to perform the specific action based on a service to be supported.
