Call Control Component for IP Caller ID Tracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice telecommunications networks, such as PSTN, provide caller identification services, but internet protocol networks lack the ability for called parties to trace and obtain identification information of calling parties during internet protocol calls.
Innovation Solution
Implementing call control components that connect internet protocol calls to endpoints, collect, and send identification information to the calling party upon request, utilizing softswitches, H.323 gatekeepers, and internet protocol service databases to manage and control the flow of identification data within the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If caller identification service is implemented in PSTN, then calling party identification can be obtained, but the service is not available for IP network calls
Solution Approach 1:
The call control component is designed to handle multiple network protocols (PSTN and IP networks) and perform unified call tracing functions across different network types. The component collects identification information from various sources including H.323 gatekeepers, SIP proxies, and PSTN switching systems, making the caller identification service universally applicable across different network infrastructures.
2Loss of information
If network administrators trace IP calls, then identification information can be gathered, but called parties cannot initiate traces
Solution Approach 1:
The system enables called parties to autonomously initiate call trace operations through their user interfaces. When a called party requests caller identification, the call control component automatically collects the necessary identification information from network elements and delivers it to the requesting user without requiring administrator intervention. This self-service mechanism empowers end users to obtain caller information independently.
3Reliability
If call control components collect identification information, then transparency and security are enhanced, but device complexity increases
Solution Approach 1:
The call control component serves as an intermediary between network elements (gatekeepers, proxies, switching systems) and end users. It centralizes the complex tasks of collecting, validating, and managing caller identification information from multiple network sources, thereby isolating the complexity within the call control component while presenting a simplified interface to users and other network elements.

AI summary
An apparatus in one example comprises one or more call control components. One or more of the one or more call control components connect an internet protocol call initiated by a communication device to an internet protocol endpoint. One or more of the one or more call control components collect identification information of the communication device and send the identification information to the internet protocol endpoint.
