Base Unit Authentication Data Transmission for Cordless Handsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of Internet telephones with handsets must manually input user authentication data for each call, making the process cumbersome.
Innovation Solution
A communication device comprising a base unit and a handset, where the base unit stores and transmits authentication data to the handset, allowing the handset to set this data for Internet telephone calls, eliminating the need for manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the telephone set stores user authentication data in the individual information storing memory for Internet telephone login, then the user does not need to input user authentication data when using the Internet telephone via the telephone set, but the handset cannot access this stored authentication data and the user must manually input it each time
Solution Approach 1:
The base unit is designed to serve multiple functions: it acts as both an Internet telephone device and an authentication data server for the handset. The base unit stores authentication data in its individual information storing memory and simultaneously provides this data to the handset via wireless communication, enabling the handset to perform Internet telephone calls without manual authentication input. This multi-functional design resolves the contradiction by making the base unit a universal authentication source for both devices.
Solution Approach 2:
The base unit functions as an intermediary between the authentication data storage system and the handset. Instead of the handset directly accessing the individual information storing memory or the user manually inputting data, the base unit receives authentication data requests from the handset, retrieves the appropriate data from its stored information, and transmits it wirelessly to the handset. This intermediary role simplifies the handset's operation while maintaining secure authentication data management.
2Adaptability or versatility
If the handset is provided with capability to communicate with external devices via the telephone set, then the handset can perform Internet telephone calls, but the user must manually input user authentication data each time resulting in troublesome operations
Solution Approach 1:
The base unit performs preliminary action by storing authentication data in advance in its individual information storing memory. When the handset needs to perform an Internet telephone call, the authentication data is already prepared and stored in the base unit, which then transmits it to the handset. This preliminary storage and preparation of authentication data eliminates the need for manual input during actual use, thereby improving ease of operation while maintaining device versatility.

AI summary
A communication device includes a base unit and a handset. The base unit includes a first communication unit, an authentication data storing unit, and an authentication data transmitting unit. The first communication unit is configured to communicate with an external device by using a communication service subject to setting authentication data into the communication service. The authentication data storing unit stores the authentication data. The authentication data transmitting unit transmits the authentication data to the handset. The handset include a second communication unit, an authentication data receiving unit, and a setting unit. The second communication unit is configured to communicate with the external device by using the communication service subject to setting authentication data into the communication service. The authentication data receiving unit receives the authentication data transmitted from the authentication data transmitting unit. The setting unit sets the authentication data received by the authentication data receiving unit into the communication service when the second communication unit attempts to communicate with the external device by using the communication service.
