Multi-Mode Mobile Station Unified Paging via Short-Range RAT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face inefficiencies in switching between multiple radio access technologies (RATs), leading to reduced throughput and increased power consumption due to the need for multi-mode mobile stations to constantly listen for paging requests across various RATs.
Innovation Solution
Implementing a method where a multi-mode mobile station establishes a connection via a short-range RAT, such as Wi-Fi, to receive signal quality measurements and paging messages for long-range RATs, thereby reducing the need to actively listen to each long-range RAT's paging channel and minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-mode mobile station constantly listens for paging requests across multiple RATs, then it can receive paging messages for long-range RATs, but power consumption increases significantly
Solution Approach 1:
The patent introduces a short-range RAT (e.g., Wi-Fi) as an intermediary communication channel. Instead of directly listening to long-range RAT paging channels, the mobile station uses the short-range RAT to receive paging information and measurements about long-range RATs. This intermediary approach reduces power consumption because short-range RATs typically require less power to maintain connectivity and can provide paging updates without requiring the mobile station to actively monitor multiple long-range RAT paging channels simultaneously.
2Adaptability or versatility
If a multi-mode mobile station switches between multiple RATs, then it can access both short-range and long-range networks, but switching efficiency decreases and throughput reduces
Solution Approach 1:
The patent combines multiple RAT monitoring functions into a unified approach through the short-range RAT connection. The mobile station maintains a single active connection via short-range RAT while receiving consolidated paging information and signal quality measurements for multiple long-range RATs. This merging eliminates the need for frequent switching between RATs, as all paging and measurement information is delivered through the single short-range connection, thereby improving switching efficiency and overall throughput.

AI summary
Certain embodiments of the present disclosure provide a method for wireless communications by a multi-mode mobile station that supports communications with a plurality of radio access technologies (RATs). The RATs may include at least one short range RAT and at least one long range RAT. The method generally includes establishing a first connection with a first network via a short range RAT supported by the mobile station, taking signal quality measurements for one or more long range RAT supported by the mobile station, and transmitting the signal quality measurements via the first connection. The method also includes receiving a paging message indicating a paging request detected on a second network, thereby implementing a unified paging process.
