Cordless Base Station Messaging Routing via Cellular Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for interconnecting cellular telephones with cordless telephone systems have limited capabilities, primarily supporting simple voice calling and limited data transfer, and require additional hardware and network connections, making them costly and unreliable for messaging services.
Innovation Solution
A system that uses a Bluetooth transceiver or hard-wire serial port to enable message routing between a cellular phone and a cordless telephone system, employing AT-commands for SMS management and an intelligent polling algorithm to minimize battery consumption while providing timely message notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional systems use additional hardware and network connections for messaging services, then messaging capability is provided, but system complexity and cost increase
Solution Approach 1:
The patent combines the cellular telephone's messaging capabilities with the cordless telephone system by integrating a messaging service interface into the base unit. This merging allows the cordless system to access cellular networking resources without requiring separate hardware infrastructure, thereby providing messaging capability while avoiding additional hardware complexity
Solution Approach 2:
The base unit is designed to perform multiple functions: traditional voice calling, data transfer, and now messaging service access. By making the base unit universal, the system can handle various communication tasks through a single integrated device rather than requiring specialized hardware for each function
2Reliability
If the cellular phone is kept close to the cordless system for messaging, then message transfer reliability is improved, but user mobility is restricted and cellular radiation exposure increases
Solution Approach 1:
The base unit acts as an intermediary between the cellular telephone and the cordless handsets. It receives messages from the cellular phone via wireless or wired connection and then distributes them to appropriate handsets. This intermediary role allows the cellular phone to be placed anywhere within standard wireless range rather than kept close to the system, reducing radiation exposure to users while maintaining reliable message transfer through the base unit's processing
3Loss of time
If continuous polling is used for message notifications, then message delivery timeliness is improved, but battery consumption increases
Solution Approach 1:
The system implements periodic polling with variable intervals rather than continuous polling. The base unit polls the cellular telephone for new messages at scheduled intervals, and can adjust these intervals based on activity patterns. This periodic approach maintains message delivery timeliness by regularly checking for new messages while significantly reducing battery consumption compared to continuous polling
Solution Approach 2:
The polling mechanism uses partial action by only initiating full message checks when certain conditions are met, such as incoming call detection or user request. Between these partial checks, the system uses lighter monitoring approaches, thereby maintaining adequate message delivery timeliness while reducing overall battery consumption compared to exhaustive continuous polling
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables extended messaging services to cordless handsets without constant proximity to the cellular phone, reducing cellular radiation and operational costs, while maintaining reliable message delivery with minimal impact on battery life.
Implementation Method 1
A Bluetooth transceiver or hard-wire serial port is used to transfer messages between the cellular phone and the cordless telephone system
Implementation Method 2
the handset and base each have a radio transmitter, receiver, and antenna to allow communication between the handset and base
Implementation Method 3
Each cell is populated with one or more low-powered radio transceivers that communicate with the cellular telephones in or about the cell
Data Source
AI summary
Systems and methods are provided for routing data messages between a cellular telephone and a cordless telephone system having a plurality of cordless handsets configured to communicate with a single cordless base station when in range. Messages are received at the cordless base station via a first radio frequency transfer protocol. The message is transmitted to the cordless base station from the cellular telephone after the cellular telephone has received the message from a cellular network. The cordless base station transmits the message to a desired one of the plurality of cordless handsets via a second radio frequency transfer protocol. The desired one of the plurality of cordless handsets is chosen based on predetermined message routing settings.
