Core Network Device Access Node Selection for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems fail to ensure that terminals of different device types or service types access access nodes that meet their specific service requirements, leading to suboptimal communication quality due to mismatched device capabilities and service needs.
Innovation Solution
A core network device determines the appropriate access node with matching device capabilities for each wireless terminal, instructing it to switch to that node for optimal service delivery, ensuring better communication quality by aligning device types and service types with supported capabilities.

Engineering Contradiction Analysis
1Loss of time
If a terminal selects a serving cell based on network signal status (signal power or signal quality), then the terminal can establish network access quickly, but the selected serving cell may not support the terminal's device type or service type requirements, leading to mismatched device capabilities and service needs
Solution Approach 1:
The network device performs preliminary actions by determining the terminal's device type and service type requirements before completing the cell selection process. The network device obtains terminal capability information, determines supported device types and service types, and uses this information to guide the terminal to select an appropriate serving cell that matches both signal quality and service requirements, rather than relying solely on post-selection compatibility checks
Solution Approach 2:
The network device acts as an intermediary between the terminal and the serving cell selection process. It receives terminal capability information, determines device type and service type requirements, and provides guidance to the terminal for selecting a suitable serving cell. This intermediary role ensures that the terminal's device capabilities are matched with appropriate network resources and service support
2Adaptability or versatility
If different access nodes support different communication types with different QoS, then the system can provide specialized services, but terminals cannot reliably access nodes that meet their specific service requirements
Solution Approach 1:
The system implements feedback mechanisms where terminals report their device type and service type requirements to the network device. The network device uses this feedback information to determine appropriate serving cells that support the required communication types and QoS levels. This feedback loop enables dynamic matching between terminal requirements and access node capabilities
Solution Approach 2:
The system changes the selection parameters from purely signal-based metrics to include device type and service type compatibility. The network device determines device type and service type requirements, and these parameters are used to filter and select serving cells that not only have good signal quality but also support the required communication types and QoS levels

AI summary
Embodiments of the present invention provide a wireless communications access method, a communications apparatus, a wireless terminal, and a system. The method includes: receiving, by a core network device, a first connection request sent by a first access node, where the first connection request carries a device type and/or a service type of a wireless terminal; determining, by the core network device according to the device type and/or the service type of the wireless terminal and a device capability of an access node that can be accessed by the wireless terminal, an access node whose device capability can support the device type and/or the service type of the wireless terminal as a target access node; and instructing, by the core network device, the wireless terminal to access a network by using the target access node. Terminals of different device types or service types access nodes meeting their service requirements, so that better communication quality is provided for wireless terminals.
