Same Number Service Call Routing via IP Network Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing call processing systems cannot support intelligent terminals and conventional terminals using the same number in both IP networks and conventional communication networks, leading to inefficient resource allocation and routing issues.
Innovation Solution
A call processing method and system that utilizes a service platform in the IP network to manage calls by adding access codes to identify same number services, allowing for the same number service processing across different communication networks, enabling connection between SIP intelligent terminals and conventional terminals using the same number.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a logic number is allocated for same number service in the current network, then the intelligent terminal and conventional terminal can share the same number, but it occupies additional number resources of the current network
Solution Approach 1:
The patent introduces a service platform as an intermediary between the intelligent terminal and conventional terminal. The service platform handles the same number service logic and call routing, eliminating the need for additional number resources in the current network. The service platform receives calls destined for the same number and routes them to the appropriate terminal based on service logic.
Solution Approach 2:
The patent extracts the same number service functionality from the current network's number resource management system. By moving this functionality to a separate service platform, the system avoids consuming additional number resources while maintaining the ability to provide same number service to both intelligent and conventional terminals.
2Adaptability or versatility
If number subscription or number section configuration is used to route calls to the soft switching network, then call routing is established, but it cannot support both intelligent terminal in soft switching network and conventional terminal in current conventional communication network to use the same number
Solution Approach 1:
The service platform is designed with universal functionality to handle calls for both intelligent terminals in the soft switching network and conventional terminals in the current conventional communication network. It provides a unified interface for same number service regardless of the terminal type or network location, eliminating the need for separate routing configurations.
Solution Approach 2:
The service platform uses access codes as a parameter change mechanism to identify same number service calls. By detecting specific access codes in the calling number or called number, the platform dynamically changes the routing behavior to handle same number service appropriately, supporting cross-network compatibility without complex configuration.
3Ease of operation
If the one-number service platform initiates new calls for all associated numbers simultaneously, then the called party can select any terminal to answer, but it increases call processing time and network load
Solution Approach 1:
The service platform performs preliminary actions by pre-configuring the associated number list and service logic before calls are made. When a call arrives, the platform quickly retrieves the pre-configured information and initiates calls to associated terminals without requiring complex real-time processing, thereby reducing call processing time while maintaining terminal selection flexibility.

AI summary
A call processing method, a call processing system and call processing equipment of a same number service are disclosed. The method includes: receiving a call which is initiated by a calling client and carries an initial called number, and sending a message of the called number with a same number service characteristic to first switching equipment in an IP network when the initial called number is a number of the same number service; and receiving a call request initiated by the first switching equipment, starting same number service processing of the initial called number according to the message carried in the call request, and calling a same number terminal corresponding to the initial called number. The embodiment of the invention helps realize the same number service between a SIP intelligent terminal in the IP network and ordinary terminals in other communication networks.
