Unified Service Control Platform for Circuit-Switched and Packet-Switched Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The simultaneous operation of circuit-switched (CS) and packet-switched (PS) service control platforms in communication networks increases operation costs and complicates the introduction of new services, as each platform requires separate configurations and updates.
Innovation Solution
A call control method that establishes a circuit-switched call leg with a terminal device and a packet-switched call leg, binding them under a packet-switched domain server to provide centralized control, reducing the need for separate CS and PS service control platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If CS and PS service control platforms operate simultaneously, then network compatibility and service coverage are improved, but operation costs and system complexity increase
Solution Approach 1:
The patent merges the CS service control platform and PS service control platform into a unified service control platform. The binding relationship established between CS domain nodes and PS domain nodes allows a single service control platform to manage both circuit-switched and packet-switched services, eliminating the need for separate control platforms and reducing overall system complexity while maintaining network compatibility.
Solution Approach 2:
The service control platform is designed with multi-functionality to handle both CS and PS domain services. By establishing binding relationships between domains and enabling cross-domain service control, the platform can provision and manage services across different network types (circuit-switched and packet-switched) through a single unified system, improving adaptability without requiring separate specialized platforms.
2Adaptability or versatility
If CS and PS service control platforms operate simultaneously, then network compatibility is improved, but operation costs increase
Solution Approach 1:
The patent combines multiple service control platforms into one unified platform that can manage both CS and PS domains. This consolidation reduces operation costs by eliminating redundant infrastructure, staff training requirements, and maintenance activities associated with running separate CS and PS service control platforms, while still providing comprehensive network compatibility through the binding mechanism.
Solution Approach 2:
The unified service control platform performs multiple functions by controlling services in both CS and PS domains through established binding relationships. This multi-functionality reduces operational overhead and costs compared to maintaining separate specialized platforms, as a single team and infrastructure can manage all service provisioning activities across different network types.
3Manufacturing precision
If separate CS and PS service control platforms are used, then service control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges service control functions for CS and PS domains into a single platform while maintaining precise control through domain-specific binding relationships. The binding between CS domain nodes and PS domain nodes ensures that service control precision is preserved for each domain type, while the unified interface simplifies the introduction of new services by allowing operators to provision services across domains through a single system rather than coordinating multiple separate platforms.

AI summary
A call control method includes: establishing a circuit-switched call leg with a terminal device; establishing a packet-switched call leg with a second party; and establishing a call connection between the terminal device and the second party through binding the circuit-switched call leg and the packet-switched call leg. A circuit-switched domain adapter and a terminal device are also provided to realize a call control to the circuit-switched terminal device by a packet-switched control platform.
