Communication Session Information Server for Active Session Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in easily and quickly identifying active communication sessions across different communication systems, leading to potential missed participation in ongoing sessions.
Innovation Solution
A communication session information server is introduced to automatically ascertain and report active communication sessions, optionally filtering results based on predefined conditions, by sending challenges to multiple session servers and consolidating responses for efficient signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a user manually checks each communication session server to identify active sessions, then the user can obtain session information, but the process becomes complex and time-consuming
Solution Approach 1:
The patent introduces a communication session information server as an intermediary that consolidates session information from multiple communication session servers. This intermediary server receives requests from user terminals, queries relevant session servers, and returns consolidated results, thereby eliminating the need for users to manually check each server and significantly reducing the time and complexity of identifying active sessions.
2Loss of information
If the communication system queries all session servers for active sessions, then complete session information is obtained, but signaling complexity increases
Solution Approach 1:
The patent segments the session information query process by having the communication session information server selectively query only those communication session servers that are relevant to the user's request. Instead of querying all session servers universally, the system divides the query task based on user-specific criteria (such as user profile, service type, or session category), thereby obtaining complete relevant information while minimizing signaling complexity.
Data Source
AI summary
In a method for determining active communication sessions, a request to determine active communication sessions is received. Queries as to whether communication sessions are currently active are sent to at least two communication session servers. The respective query answers that indicate one or more active communication sessions being controlled by the respective communication server are received. A first answer that indicates one or more active communication sessions being controlled by the at least two respective communication servers is sent. A communication session information server executes the method.
