Relaying Device Individual Calling Wireless Transceivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing relaying devices cannot perform individual calling between wireless transceivers without intercepting communication contents, as they communicate with one relaying device, and wireless devices lack simple manipulation for specifying communication partners.
Innovation Solution
A relaying device with a wireless device interface, network interface, and control unit that determines if a communication request includes wireless-device specifying information, prompting input if necessary, to ensure individual calling by specifying the correct wireless terminal device.

Engineering Contradiction Analysis
1Area of stationary object
If multiple transceivers communicate with one relaying device, then communication coverage is extended to areas where radio waves do not reach each other, but individual calling cannot be performed and communication contents can be intercepted by all connected transceivers
Solution Approach 1:
The patent segments the communication addressing system by introducing a two-level numbering structure: area numbers for identifying different relaying devices and extension numbers for identifying individual transceivers. This segmentation enables individual calling while maintaining the multi-transceiver architecture, thus preserving communication coverage while enhancing security.
Solution Approach 2:
The relaying device acts as an intermediary that implements individual calling functionality. By introducing the concept of extension numbers and implementing call routing logic in the relaying device, the system enables private communications between specific transceivers while maintaining the broadcast capability for extended coverage areas.
2Reliability
If multiple numbers are used for dialing to specify arbitrary transceivers, then individual calling is enabled, but manipulation complexity increases for wireless devices with limited buttons
Solution Approach 1:
The dialing number is segmented into two distinct parts: area number and extension number. This segmentation allows the system to maintain individual calling capability while providing a structured approach to number input that can be simplified through memory storage and recall functions on the wireless device.
Solution Approach 2:
The patent implements preliminary action by allowing users to store frequently used area-number-extension combinations in memory on their wireless devices. This enables quick recall and dialing of communication partners without manually entering multiple numbers each time, thus maintaining individual calling capability while significantly improving ease of operation.
3Reliability
If wireless devices have many buttons for complex manipulation, then individual calling can be performed, but device portability and ease of use are reduced
Solution Approach 1:
The patent applies preliminary action by pre-storing area numbers and extension numbers in the wireless device's memory. This allows users to perform individual calling with minimal button presses by recalling stored combinations, thereby maintaining individual calling capability while avoiding the need for numerous physical buttons on the device.
Solution Approach 2:
The system uses memory storage to create digital copies of frequently used communication partner information (area numbers and extension numbers). This allows the wireless device to replicate the functionality of having multiple buttons for different partners without physically adding those buttons, thus maintaining individual calling capability while preserving device simplicity.

AI summary
The present invention relates to a relaying device which performs the individual calling in response to not only a call incoming from a telephone but also a call incoming from a transceiver. When receiving a communication request from another device over a network, the relaying device determines if this communication request is accompanied by the wireless-device specifying information (ID). When the communication request is not accompanied by the ID, the relaying device sends a signal for prompting another device to input the ID. When the ID is sent in response to the sent signal, the relaying device instructs the relaying wireless device to call the wireless terminal device specified by this ID. In addition, when the communication request is accompanied by the ID, the relaying device instructs the relaying wireless device to call the wireless terminal device specified by this ID.
