Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network is configured to support worst-case scenarios, then reliability is improved, but device complexity and resource utilization efficiency deteriorate
Solution Approach 1:
The network is divided into multiple network slices, each independently configured to support specific applications or services. This segmentation allows the network to provide reliable support for different scenarios without requiring the entire network to be over-configured for worst-case conditions, thereby reducing overall complexity while maintaining reliability.
Solution Approach 2:
The network configuration is made dynamic through the ability to select and activate different network slices based on current application requirements. This dynamic approach allows the network to adapt to varying conditions in real-time, providing reliability when needed without the permanent overhead of static worst-case configuration.
2Reliability
If the network is configured to support worst-case scenarios, then reliability is improved, but productivity deteriorates
Solution Approach 1:
By segmenting the network into multiple slices with different configuration levels, resources can be allocated efficiently to match actual demand. Each slice can be optimized for its specific application, preventing the entire network from being constrained by worst-case requirements and thus improving overall resource utilization and productivity.
Solution Approach 2:
Network parameters such as bandwidth allocation, latency requirements, and resource provisioning are made changeable based on the active network slice. This allows the network to transition between different operational states, optimizing resource utilization for current conditions rather than maintaining fixed worst-case parameters continuously.
3Stability of the object's composition
If data center functionalities are located at the network core, then network stability is improved, but speed and latency performance deteriorate
Solution Approach 1:
The network architecture transitions from a single centralized location to a multi-dimensional distributed structure. Data center functionalities are replicated across multiple locations including network core and network edge, creating a hierarchical arrangement that maintains stability through central coordination while achieving speed improvements through localized data processing closer to users.

AI summary
A method for controlling data transmission within a telecommunications network involves providing interconnections to both a core network and to at least one user device via a base station. A configurable network is defined interconnecting the at least one core network and the base station. A first network slice is selected responsive to use of the configurable network by a first application. A second network slice is selected responsive to use of the configurable network by a second application. Data transmission are provided between the core network and the base station over the configurable network based on the selected first or second network slice.
