5G Message Store-and-Forward Updates for Expiry and Discard Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing MSGin5G messaging service in 5G networks lacks mechanisms for dynamically updating store and forward parameters, such as message expiry time, and does not allow the message originator to discard messages when they are no longer important, leading to potential message loss or unnecessary delivery attempts.
Innovation Solution
A method and apparatus that enable the client to update store and forward parameters, such as message expiry time, and inform the server to discard stored messages based on the client's intent, with the server responding to the client's requests and providing failure causes when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server stores messages with a fixed expiry time, then the message delivery process is simple, but the message cannot be delivered if the recipient becomes available after the expiry time
Solution Approach 1:
The patent implements dynamic message management by allowing the message originator to update store and forward parameters (such as expiry time) of stored messages. This enables the system to adapt message delivery parameters in real-time based on recipient availability, transforming the static expiry time mechanism into a dynamic one that can be adjusted without changing the overall system architecture.
2Reliability
If the server continuously attempts to deliver stored messages, then message delivery completeness is improved, but unnecessary delivery attempts waste network resources
Solution Approach 1:
The patent implements a feedback mechanism where the message originator can monitor the delivery status of stored messages and provide update requests to the server. The server responds with delivery status information, enabling the originator to make informed decisions about whether to continue delivery attempts or discard messages, thus avoiding unnecessary network resource consumption.
Solution Approach 2:
The patent allows dynamic modification of message parameters (such as expiry time and delivery priority) by the message originator. This enables flexible control over message delivery behavior, allowing the system to adjust delivery parameters based on changing conditions without requiring continuous delivery attempts.
3Adaptability or versatility
If the message originator can update store and forward parameters, then message delivery flexibility is improved, but the message management protocol becomes more complex
Solution Approach 1:
The patent extends the existing store and forward mechanism to support multiple operations (update, discard, query) through a unified message management protocol. The same server infrastructure and message storage mechanism are used for both traditional store-and-forward delivery and the new update/discard functionality, avoiding the need for separate complex systems.
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting higher data rates. The disclosure provides a method performed by server. The method includes receiving, from a terminal, a request message to update a stored MSGin5G message originated to a recipient terminal, wherein the request message includes information on an ID of a message which requires update; determining whether the message is stored based on the received ID; in case that the message is stored, performing an update procedure for the stored MSGin5G message, wherein the update procedure includes an update of a store and forward parameter associated with the stored MSGin5G message or a discard of the stored MSGin5G message; and transmitting, to the terminal a response message including information related to a result of the update procedure.
