Network Device PSM and eDRX Parameter Control via SCEF
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current implementations of Power Saving Mode (PSM) and extended Discontinuous Reception (eDRX) face challenges in coordinating network capability parameters between user equipment (UE) and service networks, leading to misconfigured timer values that result in device function issues and excessive network traffic, with a lack of standardized automation for parameter setting and troubleshooting.
Innovation Solution
Implementing PSM and eDRX services by storing data as part of subscription data and UE profile data within network devices, allowing for customized timer values based on subscriber profiles and application models, and automatically provisioning these values during attachment and tracking area update procedures, using service capability exposure function (SCEF) and network exposure function (NEF) devices to manage and control PSM and eDRX.

Engineering Contradiction Analysis
1Use of energy by moving object
If PSM and eDRX functionalities are implemented to reduce power consumption, then battery life is improved, but network capability coordination becomes complex leading to misconfigured timer values
Solution Approach 1:
The patent introduces a network device as an intermediary that stores subscription data and UE profile data containing PSM and eDRX parameters. This intermediary coordinates the timer values between the UE and service network, preventing misconfiguration while maintaining power-saving benefits. The network device acts as a mediator that ensures proper synchronization of network capability parameters.
2Reliability
If timer values are manually configured for PSM and eDRX, then device function issues can occur due to misconfiguration, but automated provisioning adds system complexity
Solution Approach 1:
The patent implements preliminary action by pre-storing PSM and eDRX timer values in the network device as part of subscription data and UE profile data before the UE attaches to the network. During attachment and tracking area update procedures, the network device automatically provisions these pre-configured values to the UE, eliminating manual configuration errors while maintaining system reliability.
3Quantity of substance
If PSM and eDRX are used to reduce network access requests, then network traffic is reduced, but troubleshooting capabilities are diminished due to lack of standardized automation
Solution Approach 1:
The patent implements feedback mechanisms where the network device monitors and manages PSM and eDRX parameter provisioning. The system maintains standardized automation for parameter setting and can track the status of timer value configurations, enabling improved troubleshooting capabilities while continuing to reduce network traffic through effective PSM and eDRX operation.

AI summary
Systems provide for provisioning, in a wireless network, in a network-service profile associated with a network-service subscriber, at least one of a power saving mode (PSM) parameter or an extended discontinuous reception (eDRX) parameter for use by a first user device; receiving a network service-related request from the first user device via an administrative non-IP packet data network (PDN) bearer established using a statically-allocated non-IP administrative access point name (APN); sending, via the PDN bearer, a first mobile terminated trigger delivery request (MT-TDR) including a bootstrap request trigger, generated by the network device, to the first user device; receiving, via the PDN bearer in response to the bootstrap request trigger, a first mobile originated originating delivery request (MO-ODR) bootstrap request; and sending, in response to the bootstrap request, a second MT-TDR including the at least one of the PSM parameter or the eDRX parameter.
