Cellular Network Message Delivery with Device Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently delivering messages, such as SMS or MMS, to users who own multiple devices, as current multi-device features do not effectively prioritize message delivery across these devices, leading to potential message loss or delayed delivery.
Innovation Solution
A method where user equipment (UE) devices register with a cellular network using priority values, allowing the network to selectively deliver messages based on these values, attempting delivery first to the highest priority device using IMS, then circuit-switched networks if necessary, and temporarily adjusting priorities if initial delivery fails, ensuring subsequent messages are sent to the newly prioritized device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If messages are distributed to all registered devices, then message delivery coverage is improved, but message delivery efficiency and reliability deteriorate due to lack of prioritization
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different devices of the same user. Each device is configured with a specific priority value (e.g., high, medium, low), creating differentiated delivery characteristics for different devices. This allows the system to maintain broad coverage across multiple devices while ensuring reliable delivery by prioritizing specific devices based on their importance or current availability.
Solution Approach 2:
The patent changes the parameter of device priority dynamically. Instead of treating all devices equally, the system introduces a priority parameter that can be set and adjusted. The network entity uses this parameter to determine delivery order and fallback behavior, transforming the uniform delivery approach into a prioritized one that improves reliability while maintaining versatility.
2Ease of operation
If messages are delivered to multiple devices simultaneously, then message accessibility is improved, but network complexity and delivery coordination worsen
Solution Approach 1:
The patent segments the message delivery process into prioritized stages. Instead of simultaneously delivering to all devices, the system divides delivery into sequential attempts based on priority levels. High-priority devices are attempted first, followed by medium-priority, then low-priority devices. This segmentation simplifies the coordination complexity while maintaining accessibility across multiple devices.
Solution Approach 2:
The patent applies preliminary action by pre-configuring priority values for each device before message delivery occurs. The network entity stores and retrieves these priority settings in advance, allowing it to make delivery decisions without complex real-time coordination. This preliminary setup reduces network complexity while ensuring messages reach accessible devices efficiently.
3Reliability
If priority-based selective delivery is implemented, then message delivery reliability is improved, but device configuration complexity increases
Solution Approach 1:
The patent applies self-service by allowing device users to configure priority settings for their own devices through user interfaces. The configuration is then automatically transmitted to the network entity during device registration or through dedicated configuration messages. This self-service approach reduces the burden on network operators and simplifies deployment while maintaining reliable prioritized delivery.
Solution Approach 2:
The patent uses preliminary action by having devices pre-configure their priority values before actual message delivery begins. These priority settings are stored in the device and automatically provided to the network entity during the registration process or through initial configuration messages. This preliminary configuration simplifies the overall system complexity by establishing delivery rules in advance rather than requiring complex real-time negotiations.

AI summary
Some embodiments relate to a cellular network which facilitates transmission of messages, such as SMS or MMS messages, to/from respective user equipment (UE) devices of a user. Each of the UE devices may provide a relative priority value indicating a priority for receipt of messages relative to the other UE devices associated with the user. When a message intended for the user is received at the cellular network, the priority information associated with each of the user's at least two UE devices may be retrieved. The message may then be selectively delivered (by the cellular network) to one of the first UE device or the second UE device based on the relative values of the first priority value and the second priority value. If a delivery attempt fails to the highest priority device, the cellular network may attempt to deliver the message to the second highest priority UE device.
