Wireless Terminal Access Node Selection by Service Capability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems fail to ensure that wireless terminals select access nodes that meet their specific device and service type requirements, leading to potential suboptimal communication quality of service.
Innovation Solution
A wireless terminal autonomously selects an access node based on its device type and service type by determining the service capability of accessible access nodes, either through cell broadcast information or pre-stored data, and chooses the node with the appropriate service capability, signal power, or priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal selects serving cell based on signal status only, then the access process is simple, but the service requirement may not be met due to lack of communication type support
Solution Approach 1:
The patent extends the selection parameters from only signal status to include communication type support capability. The terminal now evaluates multiple parameters (signal strength, service type compatibility, device type compatibility) to select the optimal access node, ensuring both operational feasibility and service requirement satisfaction.
Solution Approach 2:
The patent segments the access node selection process into distinct evaluation dimensions: signal quality assessment, service type compatibility check, and device type compatibility check. This segmentation allows the system to independently evaluate each criterion and combine results for comprehensive decision-making.
2Adaptability or versatility
If the system supports multiple device types and service types, then the system versatility is improved, but the access node selection complexity increases
Solution Approach 1:
The patent implements preliminary classification of access nodes by communication type (5G, 4G, Wi-Fi, etc.) and pre-association of service types with required communication types. This preliminary organization allows the terminal to quickly filter suitable access nodes without performing complex real-time analysis, reducing selection process complexity while maintaining versatility.
Solution Approach 2:
The patent introduces an intermediary mapping relationship between service types and communication types, and between device types and communication types. This intermediary layer simplifies the selection process by providing a structured reference framework that the terminal can query rather than performing complex compatibility analysis from scratch.
3Reliability
If the terminal autonomously selects access node based on service capability, then the communication quality of service is improved, but the information processing requirement increases
Solution Approach 1:
The patent extracts and broadcasts service capability information (communication type support) from access nodes through cell broadcast messages. This extraction allows the terminal to obtain necessary selection criteria information efficiently without requiring complex interactions or large data exchanges, reducing information processing load while enabling autonomous selection.

AI summary
Embodiments of the present invention provide a wireless communications access method, an apparatus, a processor, and a wireless terminal. The method includes: obtaining a service capability of an access node accessible by the wireless terminal, where the service capability is used to indicate communication quality of service supported by the access node; determining, as a target access node according to the service capability of the access node and a device type and/or a service type of the wireless terminal, an access node having the service capability that supports the device type and/or the service type of the wireless terminal; and accessing a wireless communications network by using the target access node. Therefore, the wireless terminal autonomously selects an access node having a service capability that can meet a communication requirement of the wireless terminal to access the wireless communications network, thereby improving communication quality of service of the wireless terminal.
