Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the identifier allocated to a terminal device is typically unchangeable, posing challenges in scenarios where adjustments are necessary, such as overlapping paging occasions in dual SIM devices, leading to inefficient battery usage and potential information loss.
Innovation Solution
A method allowing terminal devices to request adjustments to their identifiers, enabling flexible adjustment of paging occasions based on overlapping or non-overlapping communication networks, thereby optimizing power consumption and information monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the identifier allocated to the terminal device is kept unchangeable, then the system simplicity is maintained, but the adaptability to adjust paging occasions in dual SIM devices is reduced
Solution Approach 1:
The patent implements dynamic identifier adjustment by allowing the terminal device to send a first message to the network device requesting identifier modification. The network device responds with a second message containing adjustment indication information, enabling the terminal to dynamically change its identifier and corresponding paging occasion timing based on operational needs, such as avoiding overlaps in dual SIM scenarios.
Solution Approach 2:
The patent changes the identifier parameter from a static, unchangeable value to a dynamic parameter that can be adjusted through network device authorization. The adjustment indication information modifies the identifier value, which subsequently changes the paging occasion timing parameters, allowing flexible adaptation of communication scheduling without fundamental system restructuring.
2Reliability
If the terminal device monitors multiple paging occasions simultaneously, then complete paging message coverage is achieved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts paging occasion timing by modifying the identifier used for paging occasion calculation. When overlapping paging occasions are detected in dual SIM devices, the terminal requests identifier adjustment from the network device, which responds with adjusted timing parameters. This dynamic rescheduling ensures complete paging monitoring while minimizing the number of distinct paging occasions the terminal must monitor, thereby reducing power consumption.
3Adaptability or versatility
If paging occasions overlap in dual SIM devices, then both networks can be accessed, but information loss occurs and battery efficiency decreases
Solution Approach 1:
The patent implements preliminary detection of paging occasion overlaps between dual SIM cards. When an overlap is detected, the terminal device proactively sends a first message to the network device requesting identifier adjustment before any paging message loss can occur. The network device provides adjustment indication information in advance, allowing the terminal to reschedule paging occasions to avoid overlaps, thus preventing information loss while maintaining dual SIM functionality.
