Network Node Packet Discardability for Cell Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems, particularly those supporting IoT and VoLTE, face challenges in managing packet transmissions efficiently, leading to limited system capacity due to the high resource requirements of voice and video traffic, which can impact quality of service and reduce the number of supported users.
Innovation Solution
Implementing a network node that determines the discardability of packets based on service type, calculating a probability factor or scheduling adjustment factor to decide whether to transmit or discard packets, thereby optimizing resource allocation and increasing system capacity by selectively discarding packets that do not affect voice or video quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packets are transmitted to ensure quality of service for voice and video traffic, then service quality is maintained, but system capacity and throughput are reduced
Solution Approach 1:
The patent changes the transmission parameter by introducing a probability factor that determines whether to transmit or discard packets. This probabilistic approach allows the system to dynamically adjust transmission behavior based on service type and network conditions, thereby maintaining quality of service for critical traffic while freeing resources to increase overall system capacity.
Solution Approach 2:
The patent applies different transmission strategies to different service types. Critical services (voice, video) receive protected transmission with quality guarantees, while non-critical services (data traffic) can tolerate packet loss and are subject to probabilistic discarding. This local differentiation allows quality of service to be maintained where needed while maximizing system capacity overall.
2Productivity
If resources are allocated to support more users, then system capacity increases, but quality of service for existing users may deteriorate
Solution Approach 1:
The patent introduces a probability factor parameter that controls packet transmission decisions. By adjusting this parameter, the system can dynamically balance between serving more users and maintaining quality of service for existing users. The probability factor acts as a control mechanism that allows flexible resource allocation without compromising critical service quality.
3Productivity
If all packets are transmitted to maximize throughput, then data throughput increases, but resource efficiency decreases due to unnecessary transmissions
Solution Approach 1:
The patent deliberately discards non-critical packets (data traffic) with a certain probability to free up network resources. This selective discarding allows the system to recover and reallocate resources to more critical traffic or to increase overall system capacity, thereby improving resource efficiency without significantly impacting data throughput for non-critical services.

AI summary
Various communication systems may benefit from enhanced cell capacity. For example, certain embodiments may benefit from improved packet capacity by managing transmissions in a cell. A method, in certain embodiments, may include determining at a network node whether a packet is of a service type. The service type may indicate that the packet is discardable. The method may also include calculating at the network node a probability factor or a scheduling adjustment factor for transmission of the packet, when it is determined that the packet is of the service type. In addition, the method may include determining at the network node whether to transmit the packet to a user equipment based on the probability factor, or adjusting at the network node a scheduler metric based on the scheduling adjustment factor.
