P-CSCF Registration Discovery for Dynamic IMS Control Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for establishing communication sessions between user devices and network cores rely on static listings of control functions, which are inefficient and do not account for the dynamic availability and capabilities of control functions within IP Multimedia Subsystem (IMS) cores.
Innovation Solution
Implementing a system where control functions register with network data nodes upon activation, enabling dynamic configuration information to be maintained and optimized, allowing user devices to connect with available and capable control functions based on service requests, and separating control functions into groups based on availability and services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static listings of control functions are used for establishing communication sessions, then the system structure is simple and easy to implement, but the network efficiency and adaptability deteriorate because the system cannot account for dynamic availability and capabilities of control functions
Solution Approach 1:
The patent implements dynamic service registration and discovery mechanisms where control functions can register their services and capabilities with network data nodes, and where the listings are continuously updated to reflect current availability and capabilities. This transforms the static configuration into a dynamic system that adapts to changing network conditions, thereby improving network efficiency without requiring complete system redesign
Solution Approach 2:
The patent introduces network data nodes as intermediaries between user devices and control functions. These nodes maintain updated service listings and facilitate the discovery process, acting as a mediator that manages the complexity of dynamic service registration while keeping the overall system architecture manageable and scalable
2Adaptability or versatility
If static configuration information is transmitted to gateways, then the implementation is straightforward and maintenance is simple, but the adaptability and service optimization deteriorate because the configuration cannot reflect current control function status
Solution Approach 1:
The patent implements preliminary service registration where control functions register their services, capabilities, and availability information with network data nodes before actual communication sessions are established. This preliminary action ensures that when user devices need services, the information is already available and up-to-date, enabling adaptive service selection without requiring complex real-time configuration updates
Solution Approach 2:
The patent establishes feedback mechanisms where control functions continuously update their service status and capabilities with network data nodes. This feedback loop ensures that the configuration information remains current and reflective of actual control function availability, enabling the system to adapt to changing conditions while maintaining a relatively simple implementation through automated updates
Data Source
AI summary
Systems and methods for establishing a communication interface between control functions of a network core and a network data node associated with a user side packet core are discussed herein. The system can enable configuration information to be stored and dynamically updated by the network data node such that control nodes of the user side packet core requesting service from the network core are provided with up to date configuration information associated with active control functions. As control functions are activated and deactivated, the configuration information can be updated to reflect the current state of the network core and ensure that user device connects are routed to active control functions configured to provide user requested services.
