Recording Server for VoIP Call Management in IMS Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of recording services in Internet Protocol (IP) Multimedia Subsystem (IMS) networks based on Voice over Internet Protocol (VoIP) communication, which prevents users from recording voice and video calls.
Innovation Solution
An apparatus and method are introduced to provide a recording service in VoIP communication systems by establishing a bearer traffic path between calling and called portable terminals through a recording server, allowing either terminal to request and manage the recording service, and enabling service rejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a recording service is implemented in IMS network based on VoIP communication, then users can record voice and video calls, but the system complexity increases due to the need for additional recording server and path management mechanisms
Solution Approach 1:
A recording server is introduced as an intermediary component in the IMS network architecture. This recording server acts as a mediator between the VoIP communication endpoints, receiving bearer traffic paths from the IP multimedia subsystem and performing recording operations without disrupting the existing VoIP communication flow. The intermediary approach allows recording functionality to be added while maintaining the original system's operational integrity.
Solution Approach 2:
The recording service functionality is segmented into a separate recording server component rather than being integrated into the existing VoIP terminals or core network elements. This segmentation allows the recording service to be independently deployed, managed, and scaled without affecting the complexity of the terminal devices or the core IMS network infrastructure.
2Adaptability or versatility
If recording service is provided through additional path management, then recording functionality is enabled, but the ease of operation decreases due to complex path setting procedures
Solution Approach 1:
The recording server automatically performs path management operations when a recording service request is received. The system self-services by autonomously setting up the bearer traffic path between the communication endpoints without requiring manual configuration or complex user intervention. This automation simplifies the user experience while maintaining robust path management capabilities.
Solution Approach 2:
The recording server pre-establishes the necessary path management mechanisms and bearer traffic routes before actual recording begins. By performing preliminary path setup actions automatically upon service request, the system eliminates the need for users to understand or configure complex path settings, thereby maintaining ease of operation.

AI summary
An apparatus and method are provided for proving the recording service in an Internet Protocol (IP) Multimedia Subsystem (IMS). The apparatus includes a communication unit for receiving a recording request from a calling portable terminal or a called portable terminal, and a recording service manager unit coupled to the communication unit for setting a path of bearer traffic for recording a conversation between the calling portable terminal and the called portable terminal.
