Camera Manager Framework for Multi-Camera Cellular Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing multiple cameras with different fields of view in cellular wireless communication networks poses challenges, including individual configuration and optimization of network slices for uplink streaming, which are not optimized for video streaming requirements.
Innovation Solution
A framework is provided that includes a core network and Radio Access Network (RAN) with an uplink streaming network slice having guaranteed Key Performance Indicators (KPIs) for uplink streaming, allowing multiple cameras to be assigned to a subscription associated with a User Equipment (UE) device, with each camera connected via cellular and short-range wireless transceivers, and an embedded Subscriber Identity Module (eSIM) for activation and registration, enabling efficient video management and control actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are connected to a UE device via cellular and short-range wireless transceivers, then the system can support diverse fields of view and camera types, but the device complexity and management overhead increase
Solution Approach 1:
The patent introduces a camera manager component as an intermediary that handles all communication and control between the UE device and multiple cameras. This mediator abstracts the complexity by providing a unified interface for camera activation, deactivation, and control, while managing individual camera transceivers and subscriptions behind the scenes.
Solution Approach 2:
The framework implements a universal camera management system that can handle diverse camera types (body cameras, dash cameras, security cameras) through a common architecture. The camera manager provides multi-functional capabilities including activation, deactivation, control, and coordination across different camera technologies and communication methods.
2Reliability
If network slices are configured for each individual camera, then each camera can have optimized streaming parameters, but the configuration and management becomes increasingly complex
Solution Approach 1:
The patent merges multiple camera-specific network slice configurations into a unified management approach. The camera manager coordinates network slice allocation for multiple cameras through a single control point, allowing optimized streaming parameters to be maintained while reducing the operational complexity of managing individual configurations.
Solution Approach 2:
The system segments the network slice management into camera-specific optimization parameters (maintained for reliability) and unified coordination functions (managed by the camera manager to reduce complexity). This segmentation allows each camera to have its streaming requirements optimized while the overall configuration is managed centrally.
3Productivity
If guaranteed QoS classes are assigned for uplink streaming, then video streaming performance is improved, but the network resource allocation becomes more complex
Solution Approach 1:
The framework implements self-service mechanisms where the camera manager automatically handles QoS class assignment and network resource coordination based on camera activation and streaming requirements. This automation improves video streaming performance through guaranteed QoS while reducing network management complexity by eliminating manual configuration.
Solution Approach 2:
The system employs feedback mechanisms where the camera manager monitors streaming performance and dynamically adjusts QoS allocations. This feedback loop ensures optimal video streaming performance is maintained while the automated adjustment process reduces the complexity of manual network resource management.
4Ease of operation
If multiple cameras are activated and controlled through a single UE device, then centralized control is achieved, but the management overhead and processing requirements increase
Solution Approach 1:
The camera manager serves as an intermediary that provides centralized control functionality while managing the complexity of coordinating multiple cameras. It handles activation, deactivation, and control commands for all cameras through a unified interface, reducing the operational burden on the user while maintaining centralized management.
Solution Approach 2:
The management overhead is segmented between the camera manager (handling high-level coordination and control) and individual camera interfaces (handling device-specific operations). This segmentation allows centralized control to be achieved while distributing the processing requirements to reduce overall management complexity.

AI summary
A system may include one or more devices configured to register a camera device with a core network; assign the camera device to a subscription of a user equipment (UE) device registered with the core network; and assign the camera device to an uplink streaming network slice. The one or more devices may be further configured to assign an uplink streaming video Quality of Service (QOS) class to a data flow sent from the camera device to the core network, wherein the uplink streaming video QoS class guarantees at least one video streaming QoS parameter; and establish the data flow from the camera device to a destination device via the uplink streaming network slice based on the uplink streaming video QoS class.
