Convergence Server Service Delivery Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in providing diverse call services across circuit-switched and packet-switched networks, as they require separate service platforms and resource-intensive configurations for different service delivery modes, leading to increased costs and complexity.
Innovation Solution
A convergence server dynamically selects service delivery modes based on call attributes, establishing optimized signaling and media paths across both networks, allowing for efficient provision of call services using predefined modes such as IN, early media, and IMS-controlled modes, thereby minimizing resource usage and duplicating service platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate service platforms are used for circuit-switched and packet-switched networks, then service compatibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the service platform functionality into a single unified entity that can serve both circuit-switched and packet-switched networks. The service platform includes a service delivery module that dynamically selects delivery modes (circuit-switched or packet-switched) based on terminal capabilities and service requirements, eliminating the need for separate service platforms for each network type while maintaining service compatibility.
Solution Approach 2:
The service platform is designed with multi-functionality to handle both circuit-switched and packet-switched service deliveries. It incorporates a terminal capability acquisition module that detects terminal attributes and a service delivery mode selection module that adapts the delivery mode accordingly, allowing one platform to perform multiple functions across different network types.
2Adaptability or versatility
If multiple service delivery modes are supported, then service versatility is improved, but device complexity increases
Solution Approach 1:
The service delivery mode is made dynamic rather than static. The service platform continuously acquires terminal capabilities and dynamically selects the appropriate delivery mode (circuit-switched or packet-switched) based on real-time conditions. This dynamic adaptation allows the system to support multiple delivery modes without requiring complex separate configurations for each mode.
Solution Approach 2:
The system changes operational parameters (delivery mode) based on terminal capability parameters. By detecting terminal attributes such as network support capabilities and service requirements, the service platform adjusts the delivery mode parameter to optimize service delivery, enabling versatile service delivery through parameter adaptation rather than structural complexity.
3Adaptability or versatility
If service platforms are duplicated for different networks, then service compatibility is improved, but resource utilization deteriorates
Solution Approach 1:
The patent combines service platform resources into a single shared infrastructure that serves both circuit-switched and packet-switched networks. By merging previously duplicated service platforms, the system achieves better resource utilization while maintaining service compatibility through dynamic mode selection based on terminal capabilities and network conditions.

AI summary
A method for communication in a communication system includes predefining a plurality of service delivery modes having different signaling and media path configurations in circuit-switched and packet-switched networks. A request to place a call is accepted in the circuit-switched network, and a call service to be provided to the call by a service platform in the packet-switched network is identified responsively to the request.A service delivery mode is selected from the plurality responsively to an attribute of the call indicated by the request. Signaling and media paths are established for the call via the circuit-switched and packet-switched networks in accordance with the signaling and media path configurations of the selected service delivery mode. The call service is provided from the service platform to the call using the established signaling and media paths.
