Wireless Terminal Capability Reporting for 4G Network Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 4G wireless networks experience frequent changes between 4G and 2G/3G due to inappropriate configurations, leading to a heavy network load and poor user experience, as they only provide packet-switched domain services while relying on dual-standby technology to support both packet and circuit-switched domain services.
Innovation Solution
A wireless communication method where a wireless terminal, supporting both 4G and 2G/3G networks, receives a message querying its capabilities and responds by indicating it does not support 2G/3G, allowing it to maintain a connection in the 4G network for longer periods, reducing network load and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual-standby technology is used to support both PS and CS domain services in 4G network, then service compatibility is improved, but network load increases and user experience deteriorates due to frequent network changes
Solution Approach 1:
The patent segments the capability reporting process by introducing a new indication field that separately identifies CS domain service support. This allows the network to distinguish between terminals that only support PS domain (4G) and those that support both PS and CS domain services, enabling differentiated network handling and reducing unnecessary network changes for PS-only terminals.
Solution Approach 2:
The patent introduces an intermediary indication field in the capability reporting message that acts as a mediator between the terminal and network. This field provides the network with precise information about CS domain service support without requiring the terminal to actually support CS domain, allowing the network to make informed decisions about network selection and avoid frequent changes.
2Manufacturing precision
If terminal reports accurate second RAT capability to second RAT network, then network configuration accuracy is improved, but network load increases due to frequent terminal changes between 4G and 2G/3G
Solution Approach 1:
The patent extracts the CS domain service support indication from the traditional capability reporting framework and places it in a dedicated indication field. This extraction allows the network to quickly identify terminals that will cause frequent changes and prioritize them for CS domain services, while PS-only terminals can be handled more efficiently, reducing overall network load.
Solution Approach 2:
The patent changes the parameter representation by introducing a binary indication field that clearly states whether the terminal supports CS domain services. This parameter change enables the network to make rapid, accurate decisions about network configuration and terminal handling, reducing the complexity and load associated with frequent network changes.
3Stability of the object's composition
If terminal frequently changes between 4G and 2G/3G networks, then service continuity is maintained, but network load increases and user experience deteriorates
Solution Approach 1:
The patent applies preliminary action by having the terminal proactively indicate its CS domain service support capability before network changes are triggered. This allows the network to pre-configured appropriate handling strategies, such as directing PS-only terminals to remain on 4G network or prioritizing CS domain services for capable terminals, thereby maintaining service continuity while reducing unnecessary network changes and load.

AI summary
A wireless communications component that supports a first radio access technology (RAT) and a second RAT. After the wireless communications component establishes a connection with a second RAT network, the wireless communications component receives a first message sent by the second RAT network. The first message includes content that is used to query a second RAT capability of the wireless communications component. The wireless communications component sends a second message to the second RAT network. The second message is used to indicate the second RAT capability of the wireless communications component and indicate that the wireless communications component does not support the first RAT. Because the wireless communications component reports to the second RAT network that the wireless communications component does not support the first RAT, the second RAT network does not instruct the wireless communications component to be changed to the first RAT.
