Wireless Bearer Configuration via Single Logical Path Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing data transmission with varying Quality of Service (QoS) requirements, leading to increased delay and resource consumption due to the need for separate logical path configurations for each service.
Innovation Solution
A method for configuring a bearer in a wireless communication system that allows multiple data streams with different QoS to be transmitted through a single logical path, using preconfigured sessions and dynamic configuration changes based on QoS requests, reducing the need for separate logical path configurations and signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate logical path configurations are established for each service with different QoS requirements, then service quality is guaranteed, but system complexity and signaling overhead increase
Solution Approach 1:
The patent merges multiple logical paths with different QoS requirements into a single logical path by introducing a priority field in the packet header. Instead of establishing separate configured logical paths for each QoS level, the invention combines them into one path and uses priority-based scheduling to differentiate service quality, thereby reducing configuration complexity while maintaining QoS guarantees.
Solution Approach 2:
The single logical path is designed to handle multiple types of traffic with different QoS requirements simultaneously. The path becomes universal by incorporating a priority mechanism that can accommodate various service types (e.g., voice, data, video) without requiring separate dedicated paths for each service type.
2Reliability
If separate logical path configurations are established for each service, then service differentiation is achieved, but transmission delay increases due to configuration setup time
Solution Approach 1:
The invention performs preliminary configuration by pre-establishing a single logical path that is capable of handling multiple service types. Instead of configuring separate paths at the moment each service needs to start (which causes delay), the path is pre-configured with the capability to handle different QoS levels, eliminating configuration setup time when services need to be transmitted.
Solution Approach 2:
The system dynamically assigns priority levels to packets based on their service type requirements, rather than requiring static pre-configuration of separate paths for each service. This dynamic prioritization allows the single logical path to adapt to different service differentiation needs in real-time without incurring configuration delays.
3Reliability
If multiple logical paths are configured for different QoS levels, then quality of service is maintained, but network resources are consumed for path management
Solution Approach 1:
The invention combines multiple QoS-managed paths into a single logical path, thereby reducing the network resources required for path management. Instead of maintaining separate path states, routing tables, and configuration data for each QoS level, the system maintains a single path with priority-based differentiation, significantly reducing the computational and memory resources needed for path management.
4Device complexity
If a single logical path is used for multiple QoS levels, then configuration overhead is reduced, but service quality differentiation becomes difficult
Solution Approach 1:
The invention applies local quality differentiation by introducing a priority field specifically within the packet header of the single logical path. Instead of differentiating services at the path level (which would require multiple paths), the priority mechanism is applied locally at the packet level, allowing service quality differentiation to be maintained while using a single configuration-simplified logical path.

AI summary
The present invention relates to a method and apparatus for transmitting and receiving data performed by a base station in a wireless communication system. The present invention may provide a method and apparatus for receiving a first message requesting a first service quality from a device, selecting a first session for transmitting the first message according to a specific reference among at least one preconfigured session, transmitting a configuration change request message that requests a configuration change of the first session based on the first service quality to a network node, receiving a configuration change response message indicating a configuration change result in response to the configuration change request message, and transmitting the first message through the first session and the second session according to the configuration change response message.
