PoC Server Non-Notification Address Hiding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current PoC communication technologies lack a method to protect user privacy by hiding user addresses during group communication, as there is no standard for non-notification settings, leading to potential disclosure of user information.
Innovation Solution
A PoC communication server and terminal apparatus configuration that includes non-notification command obtaining and setting means, allowing users to set their addresses to non-notification within a group, with options for managing non-notification settings across multiple service providers and displaying alternative information instead of user addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user addresses are transmitted in PoC group communication, then communication functionality is enabled, but user privacy is compromised due to address disclosure
Solution Approach 1:
The patent extracts the user address information from the communication process by implementing non-notification settings. When a user sets their address to non-notification, the address is removed from being transmitted to other group members, while the communication functionality itself is preserved. This allows the system to maintain group communication capabilities while protecting specific sensitive information (user addresses) that would otherwise be disclosed.
2Reliability
If non-notification settings are implemented to protect user addresses, then privacy is enhanced, but system complexity increases due to additional management requirements
Solution Approach 1:
The patent implements self-service by allowing each user to independently set their own address notification preferences. Users can configure their own non-notification settings without requiring manual intervention from administrators or other users. The system automatically processes these individual settings and applies them to the group communication, reducing the management burden while maintaining privacy protection.
3Loss of energy
If user addresses are hidden from group members, then privacy is protected, but network resource optimization is achieved by preventing unnecessary address transmissions
Solution Approach 1:
The patent applies partial action by selectively transmitting user addresses only to those group members who have not set non-notification preferences. Instead of transmitting addresses to all members (excessive action) or to no one (no action), the system transmits addresses only where necessary - to users who have not opted for non-notification. This optimizes network resource usage by reducing unnecessary address transmissions while still maintaining communication functionality for authorized users.

AI summary
Subject to user's setting in PoC group communication, the user address of that user is set to non notification against other users. In case of starting PoC group communication, a PoC subscriber selects non notification subjects and transmits a PoC session commencement request. At that time, the caller sets his own address and/or address/addresses of all or a part of users to non notification. On a user designated as a non notification subject due to the caller's setting, PoC terminal apparatuses in receipt of a PoC session commencement request or PoC communication service controlling apparatuses undergo non notification setting processing. On a called party not selected as non notification subject users, if he/she sets his/her own user address to non notification in advance, likewise non notification processing is implemented. Even after a PoC session is established, each user can set his/her own user address to non notification and non notification service complying with user's intention is providable.
