Terminal Paging Message for Direct Downlink Data Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively determine how a network device sends downlink data to an idle or inactive terminal.
Innovation Solution
A data receiving method and a data sending method are implemented, where a terminal receives a paging message and, when indicated, obtains downlink data, allowing the network device to directly send downlink data to the terminal in an idle or inactive state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal is in idle or inactive state, then power consumption is reduced and battery life is extended, but downlink data transmission delay increases
Solution Approach 1:
The terminal performs preliminary actions by monitoring paging messages during idle/inactive states and preparing to receive downlink data. The network device also performs preliminary actions by having data ready to transmit. When a paging message indicates downlink data availability, the terminal quickly transitions to receive the data without full connection establishment, thus reducing delay while maintaining power savings.
Solution Approach 2:
The terminal dynamically adjusts its state between idle/inactive and active based on downlink data reception needs. The system transitions from a static idle state to an active receiving state only when necessary, optimizing the balance between power consumption and transmission delay by being dynamic rather than fixed in one state.
2Loss of time
If the terminal maintains connection state for fast data reception, then downlink data transmission delay is reduced, but power consumption increases
Solution Approach 1:
Instead of maintaining full connection state (excessive action), the terminal performs partial actions by monitoring only paging messages during idle/inactive states. This partial monitoring provides enough information to detect downlink data availability without the full overhead of maintaining an active connection, thus achieving fast data reception with reduced power consumption.
Solution Approach 2:
The paging message mechanism serves multiple functions: it not only pages the terminal for traditional purposes but also indicates downlink data availability. This multi-functionality allows the system to use an existing idle-state mechanism for dual purposes, avoiding the need for separate connection maintenance while still enabling fast data reception.
3Ease of operation
If traditional paging mechanism is used, then terminal can be paged in idle state, but downlink data cannot be directly transmitted
Solution Approach 1:
The patent merges the paging function with the downlink data indication function into a single paging message mechanism. The paging message now carries additional information about downlink data availability, combining two previously separate functions (paging and data notification) into one unified mechanism, enabling both terminal paging and direct data transmission indication.
Solution Approach 2:
The paging message is enhanced to serve multiple functions: traditional terminal paging, downlink data availability indication, and trigger for data reception. This multi-functional paging mechanism improves productivity by enabling direct data transmission while maintaining the ease of operation of the original paging system.
