Specialized Bearers for Latency-Sensitive Network Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications networks fail to provide adequate low-latency Quality of Service (QoS) for latency-sensitive traffic, such as multiplayer games, by routing such traffic in the same manner as non-latency-sensitive traffic, leading to suboptimal performance.
Innovation Solution
The implementation of specialized bearers with low-latency QoS parameters, which can be requested by terminals and established through a bearer-management system, allowing for the creation of dedicated connections with lower latency than standard bearers, specifically utilizing LTE data radio bearers, S1 bearers, and Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Radio Access Bearers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If latency-sensitive traffic is routed in the same manner as non-latency-sensitive traffic, then network infrastructure complexity is reduced, but latency performance deteriorates
Solution Approach 1:
The patent segments network traffic into different bearers based on latency sensitivity requirements. Standard bearers handle non-latency-sensitive traffic while specialized low-latency bearers handle latency-sensitive traffic such as multiplayer games. This segmentation allows differentiated handling of traffic types without requiring complete network redesign.
Solution Approach 2:
The patent introduces specialized low-latency bearers as intermediary transmission paths between terminals and the network core. These bearers act as dedicated channels that prioritize latency-sensitive traffic, inserting an intermediate layer of specialized routing between the terminal and standard network infrastructure.
2Loss of time
If specialized bearers with low-latency QoS parameters are implemented, then latency performance is improved, but network complexity increases
Solution Approach 1:
The patent changes QoS parameters specifically for specialized bearers, setting lower latency targets (e.g., 50ms or less) compared to standard bearers. This parameter differentiation enables the network to provide improved latency performance for specific traffic types while maintaining standard parameters for other traffic, avoiding the need to redesign the entire network.

AI summary
A telecommunication system can include routing devices, a bearer-management device, and a policy-management device. The bearer-management device can receive a request from a terminal to create a specialized bearer (SB) for a non-audio, non-video media type. The bearer-management device can determine that the request is associated with an authorized user, and then send a setup message comprising a Quality of Service (QoS) indicator to the policy-management device. The policy-management device can create the SB permitting data exchange between the terminal and a routing device. The SB can have QoS characteristics associated with the QoS indicator. In some examples, the terminal can receive a network address, determine an associated network port, and send a SIP INVITE message indicating the non-audio, non-video media type. The terminal can then exchange data on the network port with a peer network terminal.
