Application Layer Interface for MTC Power Saving Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for controlling congestion and managing power consumption in machine type communication (MTC) networks are not available to third-party companies providing services through application servers to MTC wireless transmit/receive units (WTRUs).
Innovation Solution
An interface is defined between the application server and the core network to enable the application server to request enforcement of rules and functions, such as informing WTRUs of service unavailability or resumption, and changing power saving mode settings, thereby controlling congestion and power consumption.

Engineering Contradiction Analysis
1Productivity
If an interface is defined between the application server and the core network to enable congestion control and power management, then network efficiency and power usage are improved, but device complexity and system architecture complexity increase
Solution Approach 1:
The patent introduces an interface as an intermediary layer between the application server and the core network. This interface enables third-party application servers to request enforcement of rules and functions (such as informing WTRUs of service unavailability, service resumption, and changing power saving mode settings) without requiring direct integration with the core network, thus improving network efficiency while managing complexity through a standardized communication channel.
2Use of energy by moving object
If third-party application servers are enabled to request enforcement of rules and functions on WTRUs, then power consumption is reduced, but access control and security management complexity increase
Solution Approach 1:
The interface acts as a controlled intermediary that allows third-party application servers to request power management actions on WTRUs. The core network entity receives these requests through the standardized interface, validates them against security policies, and enforces appropriate rules. This enables power consumption reduction while managing access control complexity through a centralized, standardized interface rather than requiring direct access control mechanisms in each application server.

AI summary
Procedures, mechanisms, methods, and techniques are provided that trigger power saving mode (PSM) functionality in the at least one wireless transmit receive units, group of WTRUs or subset of the group of WTRUs. The trigger may be in response to an application layer request to set one or more predetermined PSM settings, wherein the trigger originates from one or more application servers (APs) directed to a core network by way of an interface such as an SCEF that may be included on a device (e.g., a gateway, computing device, and/or the like) and may be configured for enabling the application server to request enabling and disabling PSM functionality.
