ACAF Network Device Synchronizes Connection Requests with Inactive Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Failed connection requests to devices in inactive modes, such as power savings or sleep modes, increase network traffic and decrease communication efficiency, as devices cannot respond to connection requests, leading to inefficiencies in communication networks.
Innovation Solution
The implementation of an Application Communication Assistant Function (ACAF) within the communication network, which interfaces with nodes like the Mobility Management Entity (MME) and Home Subscriber Server (HSS), manages failed connection requests by providing a target time for re-attempts when the device is expected to be active, reducing unnecessary re-transmissions and optimizing network resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a device enters inactive mode to reduce power consumption, then battery life is extended, but the device cannot respond to connection requests, leading to failed connection attempts and increased network traffic
Solution Approach 1:
The network device performs preliminary actions by detecting when a second device will enter inactive mode and proactively notifying the first device before the connection attempt occurs. This allows the first device to avoid sending connection requests during periods when the second device is inactive, preventing failed connection attempts and reducing unnecessary network traffic
Solution Approach 2:
The system implements feedback by having the network device monitor the operational states of devices and communicate this information back to other network entities. The network device receives indications of inactive mode from mobility management entities and relays this feedback to application servers, enabling them to adjust their connection strategies accordingly
2Use of energy by moving object
If the device remains in inactive mode to save battery, then energy is conserved, but network communication efficiency decreases due to repeated failed connection requests
Solution Approach 1:
The network device takes preliminary action by predicting inactive periods and notifying application servers in advance, allowing them to schedule connection attempts during active periods. This prevents the need for repeated retransmissions and maintains communication efficiency while preserving battery life
Solution Approach 2:
The network device acts as an intermediary between the mobility management entity and the application server. It receives inactive mode indications from the mobility management entity and translates this information into actionable notifications for the application server, coordinating the actions of multiple network entities to optimize both battery life and communication efficiency

AI summary
Aspects of the subject disclosure may include, for example, a network device that receives a failure message from a mobility management entity where the failure message indicates that a first connection request from an application server to an end user device failed based on the end user device being in an inactive mode, where the network device provides to the application server a target time for transmitting a second connection request to the end user device, and where the providing of the target time to the application server causes the application server to cease transmitting connection requests to the end user device until the target time. Other embodiments are disclosed.
