Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wireless communication devices using a single radio for multiple technologies face paging collisions due to conflicting message schedules from different wireless networks, making it impossible to receive messages simultaneously.

Innovation Solution

The user equipment (UE) device determines scheduling conflicts and switches communication to an alternative base station within the same network to resolve conflicts, ensuring continuous communication by prioritizing available base stations that meet quality thresholds.

1Device complexity

If a single radio is used for multiple wireless technologies, then device complexity is reduced, but paging collision occurs when schedules conflict

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system dynamically switches between different base stations based on real-time scheduling conflicts. When a conflict is detected between paging schedules of multiple wireless technologies, the UE transitions from one base station to another within the same network, allowing the single radio to adapt its operation dynamically and avoid missed messages.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a scheduling conflict detection mechanism as an intermediary layer between the radio and the paging messages. This intermediary monitors the paging schedules from multiple base stations and mediates the potential conflicts by determining when base station switches are necessary, thus protecting message reception reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the UE switches between base stations to avoid paging collision, then message reception reliability is improved, but communication stability may be affected

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The system performs preliminary actions by establishing and monitoring paging schedules from multiple base stations before actual conflicts occur. The UE proactively detects scheduling conflicts and prepares base station switch decisions in advance, allowing smooth transitions that minimize disruption to communication stability while ensuring reliable message reception.

AI summary

Maintaining communication of a wireless device and using a plurality of wireless communication technologies. A first paging message schedule may be determined for maintaining communication between the wireless device and a first base station associated with a first wireless communication technology. Similarly, a second paging message schedule may be determined for maintaining communication between the wireless device and a second base station associated with a second wireless technology. Additionally, a scheduling conflict may be determined between the first paging message schedule and the second paging message schedule. Accordingly, communication with the first base station may be switched to a third base station using the first wireless technology in response to determining that there is a scheduling conflict.
