Dynamic Delivery Timer for Mobile Network Message Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SMS delivery systems in mobile networks face inefficiencies due to the need to maintain open communication channels for extended periods, leading to potential message duplication, errors, or failure in delivery, especially when dealing with multiple mobile technology access domains and predefined delivery timers.
Innovation Solution
The system allows the target party's home network to monitor the delivery timer and inform the sending party's network of impending timeouts, enabling an extended delivery period and accurate allocation of resources based on the number of registered technology access domains, thus preventing errors and optimizing network resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the delivery timer is set to a short period (e.g., one minute) to release network resources quickly, then network resource allocation efficiency is improved, but message delivery reliability deteriorates because the message may not be delivered across multiple technology access domains within the timer period
Solution Approach 1:
The patent applies dynamics by making the delivery timer extendable rather than fixed. The timer duration is dynamically adjusted based on delivery progress and domain paging status. When the UE is successfully paged in a technology access domain, the timer is extended to allow complete delivery, resolving the contradiction between short timer (resource efficiency) and long timer (delivery reliability).
Solution Approach 2:
The patent changes the timer parameter from a static predefined value to a dynamic value that can be extended. The system monitors delivery progress and adjusts the timer parameter accordingly, extending it when delivery is in progress and reducing it when delivery is complete, thus balancing resource efficiency and delivery reliability.
2Reliability
If the communication dialogue is kept open for an extended period to ensure message delivery across multiple domains, then message delivery reliability is improved, but network resource consumption increases
Solution Approach 1:
The communication dialogue duration is made dynamic rather than static. The system extends the dialogue only as long as necessary for delivery completion, then closes it to release resources. This dynamic timing resolves the contradiction between keeping dialogue open (reliability) and closing it early (resource efficiency).
Solution Approach 2:
The system maintains continuous monitoring of delivery progress and actively manages the dialogue lifecycle. The dialogue remains open continuously only when delivery is in progress, and is closed continuously when delivery is complete or failed, ensuring resources are used only when providing useful action.
3Reliability
If the network pages multiple mobile technology access domains to locate the UE, then message delivery completeness is improved, but delivery time increases causing timer timeout and potential message loss
Solution Approach 1:
The system performs preliminary paging actions across multiple technology access domains before the timer expires. By proactively paging domains in advance and monitoring responses, the system ensures complete delivery attempts are made before timeout, resolving the contradiction between thorough paging (completeness) and time consumption.
Solution Approach 2:
The system implements feedback mechanisms where paging responses from technology access domains are monitored and fed back to the timer management system. When a domain responds with UE location, the timer is extended; when no response is received, the system knows to try other domains. This feedback loop ensures complete paging while managing time efficiently.

AI summary
An apparatus for delivering a message from an originating subscriber to a target subscriber across a communication network comprising; means for receiving in a first network a message from an originating subscriber to a target subscriber and an identifier of the target subscriber, the target subscriber being associated with the first network and the originating subscriber being associated with a second network, the message and identifier being received from the second network; means for identifying at least one network node associated with the target subscriber and being responsible for delivering messages to the target subscriber; means for selecting a network node from the at least one network node for delivery of the message; means for receiving from the second network an allowed time period for delivery of the message; means for determining the expected delivery time of the message for the selected network node; means for comparing the expected delivery time with the allowed time period for delivery; and means for forwarding the message to the selected network node for delivery to the target subscriber in dependence on the allowed time period exceeding the expected delivery time.
