Reserved Relationship Numbers for Second Line Service Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Second line service (SLS) systems are limited in their ability to leverage relationship numbers for purposes beyond routing calls between a subscriber's telecommunications device and a third party's device, lacking functionality for special operations such as voicemail notification and call termination when necessary information is missing from the call signal.
Innovation Solution
The SLS platform utilizes reserved relationship numbers to perform special operations, including voicemail notification and call routing, by querying a central database to map subscriber and third party numbers, even when the call signal lacks necessary identification information, and using these numbers to redirect calls and messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the SLS system uses standard relationship numbers for call routing, then call routing functionality is achieved, but the system cannot perform special operations such as voicemail notification and call termination when information is missing
Solution Approach 1:
The patent applies universality by making the relationship number system multi-functional. Reserved relationship numbers are not only used for their traditional call routing function but also for special operations such as voicemail notification, call termination, and other value-added services. This allows a single number type to serve multiple purposes, enhancing system versatility without requiring entirely separate mechanisms for each function.
Solution Approach 2:
The patent segments the relationship number space into two distinct categories: standard relationship numbers for常规 call routing and reserved relationship numbers for special operations. This segmentation allows the system to differentiate between routine and special functions, enabling the SLS platform to route different types of operations to appropriate handling procedures based on the number type encountered.
2Reliability
If the SLS platform requires complete call signal information for routing, then routing accuracy is improved, but the system cannot handle calls or messages lacking necessary identification information
Solution Approach 1:
The patent applies preliminary action by pre-assigning reserved relationship numbers to specific special operations and functions. When the SLS platform encounters a reserved relationship number, it can immediately identify the intended operation (such as voicemail notification or call termination) without requiring complete call signal information. This preliminary configuration enables the system to handle incomplete or minimal information scenarios reliably.
Solution Approach 2:
The reserved relationship number acts as an intermediary that carries implicit operational instructions. Instead of requiring complete caller identification and routing information in the call signal, the reserved relationship number itself serves as a mediator that tells the SLS platform what operation to perform, bridging the gap between incomplete information and successful operation execution.
3Ease of operation
If the SLS system leverages only normal relationship numbers, then call routing between subscriber and third party is achieved, but additional value-added operations cannot be performed
Solution Approach 1:
The patent extends the universality principle by enabling relationship numbers to serve dual purposes. Normal relationship numbers continue to handle standard call routing, while reserved relationship numbers enable value-added operations. The system maintains simplicity for routine operations while gaining enhanced operational capability through the reserved number mechanism, allowing a single number type to fulfill multiple roles.
Solution Approach 2:
The patent merges the concepts of call routing and special operations into a unified relationship number framework. By combining both functions within the same number system (with distinct reserved numbers for special operations), the system achieves operational versatility while maintaining the simplicity and familiarity of the original call routing mechanism. This merging eliminates the need for separate systems for different operations.

AI summary
A method and system for the leveraging a reserved relationship number by an SLS platform and/or SLS phone module for the purpose of performing special operations other than making an SLS call available for termination at a subscriber TD and/or a third party TD involve associating the SLS phone number of the subscriber, the primary number of the subscriber and a next set of instructions via a common reserved relationship number.
