Network Interface Proxy for IMS Voice Service Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in simplifying the integration of voice call services for user devices with carrier provider networks, particularly in IP multimedia subsystem networks.
Innovation Solution
A method and system for carrier integration through a user network interface proxy, which involves receiving requests from mobile devices, authenticating companion devices, obtaining SIP credentials, registering these credentials with a network interface proxy, and establishing voice services between companion devices and the carrier's IMS network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voice call services are provided over IP packet-switched networks for user devices, then adaptability to modern smart devices is improved, but integration complexity with carrier provider networks increases
Solution Approach 1:
A network interface proxy is introduced as an intermediary component between user devices and the IMS network. The proxy handles complex registration, authentication, and signaling functions, allowing companion devices to integrate with the carrier network without requiring complex integration logic in each device. The proxy translates and manages SIP credentials, mediates signaling traffic, and simplifies the integration process for diverse IP-based devices.
2Adaptability or versatility
If multiple companion devices are integrated with the carrier network, then service versatility is improved, but registration and management complexity increases
Solution Approach 1:
The network interface proxy is designed as a universal platform that can handle registration, authentication, and signaling for multiple types of companion devices simultaneously. It provides multi-functional capabilities including SIP credential management, network interface mediation, and centralized registration for diverse devices (smartphones, tablets, computers, IoT devices), eliminating the need for device-specific integration procedures.
3Reliability
If SIP credentials are registered for each companion device individually, then authentication security is improved, but processing time and operational complexity increase
Solution Approach 1:
The network interface proxy consolidates SIP credential registration and management for multiple companion devices into a unified process. Instead of individually registering each device, the proxy batches and manages credentials centrally, maintaining security through proper authentication while significantly reducing operational steps. The proxy combines registration operations and manages credential lifecycles (issuance, renewal, revocation) in a centralized manner.

AI summary
A method for carrier network integration through a user proxy interface includes receiving a request from a mobile device associated with a subscriber of a carrier provider to establish voice services with the carrier provider for a companion device linked to the mobile device. The request includes a subscriber identifier of the mobile device. The method also includes authenticating the companion device based on the subscriber identifier, obtaining session initiation protocol (SIP) credentials corresponding to the subscriber identifier, and registering the SIP credentials for the companion device at a network interface proxy. The network interface proxy is in communication with an internet protocol multimedia subsystem (IMS) of the carrier provider and the companion device. The method also includes establishing voice services between the companion device and the IMS through the network interface proxy using the SIP credentials.
