SMS Routing Server for Alternative Terminal Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SMS message delivery systems are inflexible and require significant effort to configure distribution criteria, leading to errors and long delivery times, as they do not efficiently support delivery to alternative terminals or account for temporary unavailability of mobile devices.
Innovation Solution
A method and system that uses an SMS routing server to filter and forward SMS messages to alternative terminals based on user-defined criteria, with confirmation of availability before transmission, and supports conversion to different data formats, utilizing protocols like SIP for connection setup and temporary storage for undeliverable messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SMS messages are routed through a conventional SMSC, then message delivery reliability is maintained through storage and forwarding mechanism, but delivery time increases significantly due to increasing throughput
Solution Approach 1:
The patent segments the SMS delivery path by introducing a parallel routing mechanism. Messages are divided into two streams: conventional SMSC routing for reliability and direct routing through alternative terminals for speed. This segmentation allows the system to achieve both reliability and reduced delivery time by selecting appropriate paths based on terminal availability.
Solution Approach 2:
The patent introduces an intermediary mechanism (availability checking system) that mediates between the SMSC and alternative terminals. This intermediary checks terminal availability and routes messages appropriately, preventing loss of messages while enabling direct delivery to available terminals, thus resolving the contradiction between reliability and delivery time.
2Adaptability or versatility
If distribution criteria are configured through the network operator via cumbersome procedures, then message routing control is achieved, but system complexity and configuration effort increase significantly
Solution Approach 1:
The patent enables self-service by allowing users to directly configure their own alternative terminals and distribution criteria without network operator intervention. Users can manage their message routing preferences autonomously, which dramatically reduces configuration effort and system complexity while maintaining full adaptability in message routing control.
Solution Approach 2:
The patent implements preliminary action by having users pre-configure their alternative terminals and message routing preferences in advance. This preliminary configuration is stored and automatically applied when messages need to be delivered, eliminating the need for complex real-time configuration procedures through network operators.
3Reliability
If conventional SMSC stores all incoming SMS messages, then no messages are lost during recipient unavailability, but delivery time increases and system burden increases
Solution Approach 1:
The patent applies dynamics by making the message storage and forwarding mechanism adaptive rather than static. Instead of always storing messages in the SMSC, the system dynamically checks terminal availability and forwards messages directly when terminals are available, or stores them temporarily when unavailable. This dynamic approach maintains reliability while significantly reducing delivery time for available terminals.
Solution Approach 2:
The patent uses preliminary action by checking terminal availability before message delivery. This preliminary check prevents unnecessary storage in the SMSC for terminals that are currently available, enabling direct forwarding and reducing both delivery time and system burden while maintaining message retention capability for truly unavailable terminals.
Data Source
AI summary
The method involves delivering a short message service (SMS) message generated by a mobile terminal or a stationary message generating unit into a switching unit of a network operator for filtering the message based on defined distribution criteria. Alternative addresses provided in a network operator side-profile database are used as defined distribution criteria. The addresses are directly configured by a user depending on the requirement of requested alternative terminals e.g. mobile radio telephone, to selectively transfer SMS-messages that are suggested for the user to one terminal. An independent claim is also included for a system for switching of SMS messages within a telecommunication network.
