Enterprise DBCC Bandwidth Control Across 4G and 5G Cores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network slicing solutions are cost-prohibitive for small to mid-sized enterprises and require expensive 5G network infrastructure, while traditional private networks are ill-suited for these enterprises, and existing 4G core equipment does not support network slicing.
Innovation Solution
Implement dynamic bandwidth capacity control (DBCC) using both 4G and 5G core equipment, reserving a predetermined amount of bandwidth for client devices meeting specific criteria, and dynamically adjusting bandwidth allocation based on binding and unbinding of client devices to a DBCC group session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slicing is implemented for enterprises, then quality of service and bandwidth guarantees are improved, but cost and infrastructure requirements worsen
Solution Approach 1:
The patent applies universality by enabling a single network infrastructure to serve multiple purposes: it supports both traditional best-effort delivery and DBCC-based bandwidth guarantees using existing 4G and 5G core equipment. The system provides enterprise-grade QoS guarantees without requiring separate dedicated infrastructure, allowing the same network resources to fulfill multiple service levels simultaneously.
Solution Approach 2:
The patent implements copying by creating virtual bandwidth reservations and logical network slices through software-based DBCC mechanisms rather than physical infrastructure duplication. Instead of building separate dedicated networks for each enterprise, the system creates virtual copies of bandwidth capacity and service guarantees through policy enforcement functions that replicate enterprise-specific QoS requirements across the shared infrastructure.
2Reliability
If bandwidth is reserved for specific client devices, then quality of service is improved, but bandwidth availability for other users worsens
Solution Approach 1:
The patent applies dynamics through dynamic bandwidth capacity control that adjusts bandwidth allocation in real-time based on actual network conditions and client device binding states. The DBCC mechanism continuously monitors network load, active client devices, and service requirements to dynamically resize reserved bandwidth capacity, ensuring guaranteed service for bound devices while automatically making unused capacity available to other users.
Solution Approach 2:
The patent implements feedback through a closed-loop DBCC system that continuously monitors network performance, client device binding status, and bandwidth utilization. The policy control function receives feedback about actual bandwidth consumption and network conditions, then adjusts reservation levels and allocation policies accordingly, balancing guaranteed service for subscribed devices with available capacity for other users based on real-time network state.

AI summary
Systems and methods provide an affordable private bandwidth reservation and control solution for enterprises that can be implemented using both 5G and 4G core equipment. Namely, an enterprise can purchase/contract for a pre-determined amount of bandwidth (e.g., 1 Gbps) that a Communication Service Provider (CSP) will reserve for connected client devices of the enterprise that meet a set of criteria defined by the enterprise/CSP: i.e., dynamic bandwidth capacity control (DBCC) group criteria. Client devices that meet this DBCC group criteria may be “bound” to a DBCC group session. If a bound client device no longer meets the DBCC group criteria, the client device may be unbound from the DBCC group session. As client devices bind and unbind from a DBCC group session, examples can dynamically modify an aggregation bandwidth capacity control policy that defines bandwidth allocation for client devices bound to the DBCC group session.
