Business Server Duplex Messaging Identifier Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Business messaging systems face cost inefficiencies and challenges in routing reply messages due to the requirement of unique public identifiers for each user, especially in systems with a large number of users, leading to prohibitively expensive rentals of phone numbers for SMS services.
Innovation Solution
A system and method that uses a business server to manage public identifiers, allowing multiple business users to share a limited number of public identifiers, and employs an API to interact with SMS systems, enabling duplex message exchange by associating business users with mobile devices and switching to temporary identifiers when necessary, thereby reducing the need for individual phone numbers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a unique public identifier (phone number) is rented for each business user to enable duplex message exchange, then message routing reliability is improved, but system cost increases prohibitively
Solution Approach 1:
The patent merges multiple business users under a single public identifier (the business server's identifier). Instead of each user having their own unique identifier, multiple users share the business server's identifier, dramatically reducing the number of public identifiers needed while maintaining routing capability through additional metadata fields.
Solution Approach 2:
The patent segments the identifier functionality into two parts: the public identifier (shared by the business server) and internal user identifiers (unique to each user). This segmentation allows the public identifier to be reused across multiple users while internal identifiers maintain uniqueness for accurate routing.
2Quantity of substance
If a limited number of public identifiers is rented to reduce costs, then system cost is reduced, but the ability to route reply messages to specific users is lost
Solution Approach 1:
The patent introduces an intermediary mechanism (the business server) that sits between the SMS system and individual users. The server uses its single public identifier to receive messages and then routes them to appropriate users using internal identifiers, acting as a mediator that preserves user identification capability without requiring multiple public identifiers.
Solution Approach 2:
The patent adds another dimension to the identification system by introducing internal user identifiers as a secondary layer. Instead of relying solely on the public identifier dimension, the system now uses a two-dimensional identification approach: public identifier for receiving messages and internal identifier for routing, preventing information loss.
3Quantity of substance
If multiple business users share a single public identifier, then cost efficiency is improved, but message routing complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the business server automatically manages the routing process using pre-configured mappings between internal user identifiers and the shared public identifier. The system handles the routing complexity internally without requiring external intervention, making the shared identifier approach viable despite the increased routing logic.

AI summary
A system for exchanging messages between a business user and a mobile device, and methods for making and using the same. The system may include a business server, an application programming interface (“API”) and/or an SMS database. The business server may be configured to exchange messages with the business user and to obtain a public identifier for the business user to enable duplex message exchange between the business user and the mobile device by either retrieving the public identifier or associating the business user with the mobile device and a public identifier. The business user may be unambiguously determined according to the public identifier or a combination of the mobile device and the public identifier, which may enable the mobile device to direct a reply message to the business user that may be the sender of a direct message.
