Short Range Radio Transceiver Voice Call Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication devices lack integrated voice and data communication capabilities, particularly in devices without a cellular radio transceiver, limiting their ability to establish voice calls and access data services effectively.
Innovation Solution
A communication system comprising a first electronic device with a short range radio transceiver and a second electronic device with both short and long range radio transceivers, including a cellular radio transceiver, allows for voice call initiation and data access by intercepting content requests, translating dialed digits into AT commands, and mediating data sessions via short and long range radio links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a device lacks a cellular radio transceiver, then the device structure is simpler and cost is reduced, but the device cannot establish voice calls or access data services effectively
Solution Approach 1:
The patent employs a companion device with cellular capabilities as an intermediary to enable voice call functionality in a device without a cellular transceiver. The companion device receives dialed digits from the first device via short range radio, establishes the voice call through its cellular radio transceiver, and mediates the communication connection, allowing the simpler device to access voice service without incorporating complex cellular hardware
2Ease of manufacture
If a device lacks a cellular radio transceiver, then manufacturing cost is reduced, but the device cannot access data services effectively
Solution Approach 1:
The companion device acts as a mediator for data service access. When the first device needs to access data services requiring cellular connectivity, the companion device receives the data request via short range radio link, establishes a data session through its cellular data transceiver, and relays data traffic between the first device and the cellular network, enabling affordable devices to access data services without expensive cellular hardware
3Adaptability or versatility
If voice call functionality is added to a device without cellular capability, then communication versatility is improved, but device complexity increases
Solution Approach 1:
The patent segments communication functionality into two distinct devices: a simple device handling user interface and short range communication, and a companion device handling cellular radio operations. This segmentation allows the first device to maintain simplicity while gaining voice call capability through the companion device's cellular transceiver, with each device optimized for its specific function
4Device complexity
If short range radio link is used for digit transmission, then device portability is improved, but communication range is limited
Solution Approach 1:
The patent transitions from a single-dimension communication model to a two-dimensional communication architecture. The short range radio link operates for local device-to-companion communication, while the cellular radio transceiver provides long-range network communication. This dimensional change allows the system to maintain device portability with short range radios while achieving extended communication range through the companion device's cellular connection to the wide-area network
Data Source
AI summary
A communication device is provided. The communication device comprises a short range radio transceiver, a cellular radio transceiver, a speaker, and a microphone. The short range radio transceiver wirelessly receives dialed digits, the device establishes a voice call via the cellular radio transceiver based on the dialed digits, the cellular radio transceiver transmits voice received from the microphone, and the device presents voice received via the cellular radio transceiver over the speaker.
