Service Node Caching for Wireless Delivery Receipts

Solution Overview

Problem

Current communication systems face inefficiencies in delivering message delivery receipts due to the need for repeated queries to locate service nodes, leading to increased network traffic and slower delivery confirmation times.

Innovation Solution

A method and system that cache the identifier of a service node serving the sending wireless communication device upon receiving a data message with a delivery receipt request, allowing for direct transfer of the delivery receipt without rediscovering the node's location, thereby reducing unnecessary queries and expediting the receipt delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a HLR query is performed to obtain the location of the MSC serving the sending device for each delivery receipt, then the delivery receipt can be transmitted to the correct device, but network traffic increases and delivery confirmation times slow down

Engineering Contradiction:

Improvedelivery receipt transmission accuracyVSAvoiddelivery confirmation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs the HLR query and obtains the MSC location information in advance when the original message is delivered, storing this information for later use. When the delivery receipt needs to be sent, the pre-obtained MSC location is used directly without performing another HLR query, thus resolving the contradiction between ensuring accurate delivery (requiring HLR query) and reducing time loss (avoiding repeated queries).

2Reliability

If a HLR query is performed to obtain the location of the MSC serving the sending device for each delivery receipt, then the delivery receipt can be transmitted to the correct device, but network congestion increases

Engineering Contradiction:

AI summary

A data message service system comprises a communication transceiver and a processing system. The communication transceiver is configured to receive a data message from a first wireless communication device for delivery to a second wireless communication device, wherein the data message indicates a delivery receipt request. The processing system is configured to, responsive to the delivery receipt request, store an identifier of a service node serving the first wireless communication device. The processing system is further configured to direct the communication transceiver to transfer the data message for delivery to the second wireless communication device, and transfer a delivery receipt for delivery to the first wireless communication device using the identifier of the service node serving the first wireless communication device.
