Mobile Device Transceiver Power Management via Location-Based Service Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices with multiple transceivers experience reduced battery life due to continuous beacon signaling to maintain connections with cellular networks, as they attempt to determine availability of service across different wireless communication technologies, leading to unnecessary power consumption.
Innovation Solution
A method where mobile telecommunication devices use a Global Positioning System to determine their location and access a stored record of available wireless communication services, activating only the necessary transceivers based on service availability, and deactivating them when not in use to conserve power, while also monitoring movement to switch between available services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile telecommunication devices use multiple transceivers to support multiple wireless communication services, then adaptability is improved, but power consumption increases
Solution Approach 1:
The device determines its current location and checks a stored record of wireless communication service availability before activating transceivers. This preliminary action allows the device to anticipate which transceivers will be needed and avoid activating those for services not available in the current area, thereby reducing power consumption while maintaining adaptability
Solution Approach 2:
The device dynamically activates or deactivates specific transceivers based on real-time location and service availability information. Instead of keeping all transceivers continuously active or using a static configuration, the system adapts its transceiver activation state according to the current operational context, optimizing the balance between adaptability and power consumption
2Reliability
If transceivers continuously send beacon signals to determine service availability, then reliability is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary determination of service availability by checking location against a stored record before continuously sending beacon signals. This preliminary check filters out services that are not available in the current area, eliminating unnecessary beacon signaling and reducing power consumption while maintaining reliable service detection for actually available services
Solution Approach 2:
Instead of continuously activating all transceivers to send beacon signals, the system partially activates only those transceivers corresponding to services that are confirmed to be available in the current location. This partial action approach maintains sufficient reliability for service detection while significantly reducing the excessive power consumption that would result from full continuous activation

AI summary
Disclosed herein are methods and mobile telecommunication devices configured to operate within a cellular telecommunication network using multiple wireless communication services or technologies. Methods may include obtaining, by a mobile telecommunication device, its current location. The mobile telecommunication device may then determine, such as from a stored record or from an internet or telecommunication network link, which particular wireless communication services are available in a local area of the cellular telecommunication network. The mobile telecommunication device may then modify operation of its transceiver equipment for the wireless communication services, such as by activating the transceiver equipment if the wireless communication service is available, or reducing power usage, such as beaconing, for a wireless communication service that is not available.
