Network Selection Logic for Telecommunication Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication systems require expensive and complex network gateways to connect calls between different types of networks, such as PSTN and VOIP, making calls inefficient and costly.
Innovation Solution
A method and apparatus that allow communication devices to select a network for a call based on the type of network used by the called communication device, using a network selection application that queries local and remote databases to identify the appropriate network and establish a communication session, potentially overriding the selected network if needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network gateways are used to connect calls between different types of networks, then communication compatibility between dissimilar networks is improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts the network selection logic from the gateway infrastructure and places it directly in the communication device. The device queries a database to determine the called party's network type and autonomously selects the appropriate network, eliminating the need for gateways to perform network translation or protocol conversion.
Solution Approach 2:
The patent introduces a database as an intermediary between the communication device and the network. The database stores mappings between called identifiers and their associated network types, allowing the device to make informed network selection decisions without requiring complex gateway infrastructure.
2Adaptability or versatility
If network gateways are used to connect calls between different types of networks, then communication compatibility between dissimilar networks is improved, but cost increases
Solution Approach 1:
The patent removes the expensive gateway infrastructure from the system architecture. By enabling communication devices to independently select networks based on database lookups, the system eliminates the need for costly gateway hardware and associated maintenance expenses.
Solution Approach 2:
The patent replaces expensive, permanent gateway infrastructure with inexpensive, software-based database queries executed by standard communication devices. This substitution dramatically reduces the cost per call while maintaining network compatibility.
3Device complexity
If communication devices autonomously select networks based on called identifier, then gateway complexity is reduced, but network selection accuracy must be improved
Solution Approach 1:
The patent performs preliminary actions by pre-populating a database with mappings between called identifiers and their associated network types. This advance preparation allows communication devices to quickly and accurately determine the appropriate network without requiring complex real-time analysis or trial-and-error selection.

AI summary
A method, apparatus, and computer usable program product for selecting a network for telecommunication are provided. A type of network supporting a called identifier is identified. Several types of networks are accessible to a calling communication device. A database is queried with a query including the called identifier to identify the types of networks that are accessible to a called communication device. A network corresponding to the called communication device is selected at the calling communication device. A communication session is established between the calling and called communication devices using the selected network.
