Control Plane QoS by Service Domain and Radio Bearer Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack the ability to differentiate quality of service (QoS) and other parameters for control plane signaling based on specific services, resulting in uniform treatment of NAS messages regardless of the associated service type, which can lead to inefficiencies in communication management.
Innovation Solution
Implementing network enhancements to support QoS differentiation in control plane and data plane signaling by associating each radio bearer with a specific QoS, priority, and security protocols based on the related service domain, allowing tailored communication management for different services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform QoS treatment is applied to all control plane signaling, then system complexity is reduced and ease of operation is improved, but resource utilization efficiency deteriorates and service differentiation capability is lost
Solution Approach 1:
The patent segments control plane signaling into service-specific domains, where each service domain (e.g., voice, data, messaging) has its own QoS parameters and radio bearer configurations. This allows differentiated QoS treatment for different services while maintaining uniform handling within each service domain, resolving the contradiction between simplicity and efficiency.
Solution Approach 2:
The patent applies local quality by assigning specific QoS characteristics (priority, reliability, latency requirements) to each service domain's radio bearers. Each service domain receives tailored QoS parameters appropriate to its requirements, enabling efficient resource allocation without requiring complete system-wide complexity.
2Productivity
If service-specific QoS differentiation is implemented, then resource utilization efficiency and service quality are improved, but system complexity and device coordination requirements increase
Solution Approach 1:
The patent introduces service domain entities as intermediaries between the core network and the radio access network. These service domains act as mediators that translate service requirements into specific QoS configurations for radio bearers, reducing the complexity burden on individual devices while enabling fine-grained QoS differentiation.
Solution Approach 2:
The patent implements preliminary action by pre-configuring QoS parameters and radio bearer types for each service domain before actual communication occurs. This advance configuration reduces real-time processing complexity and enables efficient service-specific QoS handling without increasing operational device complexity.
3Reliability
If granular control parameters are assigned per service domain, then signaling reliability and security are enhanced, but information processing complexity and coordination overhead increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting QoS parameters (priority levels, reliability requirements, security configurations) based on the specific service domain. Each service domain's control plane signaling uses parameters optimized for its requirements, enhancing reliability without requiring complex coordination for parameter management across all services.

AI summary
Methods, systems, and devices for wireless communication are described. A wireless network may include a UE that may communicate with one or more service domains, such as via a network entity. A service domain may indicate control information to the network entity, the UE (e.g., via the network entity or directly), or both, where the control information may indicate a type of radio bearer associated with the service domain and a corresponding quality of service (QoS), among other parameters. Service domains may be associated with respective QoSes according to which signals are communicated via related types of radio bearers. As such, signaling may be communicated between the UE, the network entity, and the one or more service domains via radio bearers in accordance with corresponding QoSes.
