UE Downlink Data Control via Dormancy Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In packet-based telecommunications networks, especially in roaming scenarios, there is a need to regulate downlink data traffic to manage costs and conserve battery life, as users incur unnecessary charges and face device battery drain due to continuous data reception, even when inactive.
Innovation Solution
User Equipment (UE) with an Internet Protocol (IP) address determines when no downlink data is needed and sends a message to infrastructure nodes to stop data transfer, using existing communication signals like fast dormancy signals, allowing it to retain the IP address for uplink data and reduce network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously receives downlink data in packet-based networks, then the UE maintains connectivity and can receive data from any service, but the user incurs unnecessary charges and battery life is drained, especially in roaming scenarios
Solution Approach 1:
The UE dynamically transitions between connected and dormant states based on downlink data activity. When no downlink data is received for a threshold period, the UE enters a dormant state where it stops monitoring downlink data, thereby conserving battery energy while maintaining the ability to quickly resume connectivity when needed.
Solution Approach 2:
The UE autonomously determines when to enter dormant state by monitoring its own downlink data reception status. The UE independently decides to stop receiving downlink data and send dormancy indications to the network without requiring external control, enabling self-managed energy conservation.
2Speed
If the UE continuously receives downlink data to maintain connectivity, then the UE can immediately receive data from any service, but unnecessary data traffic is received consuming network resources and increasing cost
Solution Approach 1:
The system dynamically adjusts data reception based on actual need. The UE monitors downlink data reception and transitions to a dormant state when no data is received, thereby reducing the volume of data traffic processed while maintaining the capability to quickly resume full data reception when services need to communicate.
Solution Approach 2:
The patent extracts the unnecessary downlink data reception from the continuous connectivity model. By removing the requirement to continuously monitor and receive downlink data when inactive, the system eliminates wasteful data traffic while preserving essential connectivity functionality through on-demand resumption.
3Use of energy by moving object
If the UE sends frequent messages to indicate no downlink data is needed, then battery life is conserved, but network signaling load increases
Solution Approach 1:
Instead of sending frequent individual messages, the UE implements periodic dormant state transitions. The UE enters dormant state after a threshold period without downlink data and remains in this state until triggered to resume, thereby reducing signaling frequency while maintaining effective battery conservation.
Solution Approach 2:
The patent merges multiple potential signaling events into a single dormancy indication. Rather than sending separate messages for each observation of no downlink data, the UE consolidates these into one dormancy state transition and indication, reducing overall signaling load while achieving the same energy conservation effect.

AI summary
The present invention relates to control of downlink data in a packet based telecommunications network and in particular to UE control of downlink data. This is provided in devices and methods for handling such control, for instance a user equipment (101), UE, in a telecommunications network (100). The UE has an associated Internet Protocol, IP, address. The UE comprises at least one processing unit (201), at least one computer readable storage unit (202), at least one communications interface (203), and wherein the processing unit is arranged to execute instructions sets stored in the storage unit for determining that no downlink data is to be received on the communication interface and sending a message using the communication interface to an infrastructure node (103, 104) indicating that no downlink data is to be transferred to the UE.
