Network-Initiated MSS Idle Mode Entry in Wireless MAN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless Metropolitan Area Network (MAN) technologies do not specify the process of a Mobile Station System (MSS) entering idle mode initiated by the network, leading to instability and inefficiency, particularly when the network requires the MSS to enter idle mode without a delay or when the MSS needs time to interact with hosts.
Innovation Solution
A method for the network side to enable an MSS to enter idle mode by sending a DREG_CMD message and receiving a DREG_REQ message, with the option to allow direct entry or require a delay, and by updating the anchor PC/LR with relevant parameters, thus standardizing and stabilizing the idle mode entry process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network side initiates idle mode entry without specifying a standardized process, then the MSS can enter idle mode, but the process becomes unstable and inefficient
Solution Approach 1:
The patent segments the idle mode entry process into distinct phases: network initiation phase (SBS sends idle mode entry indication), MSS processing phase (MSS interacts with hosts), and completion phase (MSS enters idle mode). This segmentation provides clear procedural boundaries and improves process stability without excessive complexity.
Solution Approach 2:
The patent introduces a preliminary action mechanism where the network side can indicate the desired idle mode entry time in advance. The MSS receives this indication and prepares accordingly, allowing for coordinated resource management and stable process execution.
2Loss of energy
If the MSS enters idle mode immediately without delay, then system resources are conserved, but the MSS cannot complete interactions with hosts
Solution Approach 1:
The patent implements a dynamic delay mechanism where the idle mode entry timing is flexible rather than fixed. The MSS can adjust the entry time based on host interaction requirements, while the network side accommodates this variability. This dynamic approach balances resource conservation with interaction completion.
Solution Approach 2:
The patent introduces feedback mechanisms where the MSS informs the network side about its interaction status and required delay time. The network side uses this feedback to manage resources appropriately, allowing delayed idle mode entry when needed while maintaining overall system efficiency.
3Adaptability or versatility
If the network side requires customizable delay scenarios for idle mode entry, then MSS interaction requirements are met, but the control mechanism becomes more complex
Solution Approach 1:
The patent uses parameter changes to achieve delay scenario flexibility. Specifically, the idle mode entry time parameter can be adjusted based on interaction requirements, and the SBS sends appropriate indications to the MSS. This parameter-based approach provides adaptability without requiring complex control mechanisms.

AI summary
The present invention provides a method as regards how a network side gets a MSS into the idle mode in a wireless MAN, including: the PA/BS sends a DREG_CMD to the MSS; the MSS sends a DREG_REQ message to the PA/BS, according to the DREG_CMD message, requesting to enter the idle mode; the PA/BS releases the link of the MSS and updates the data of the anchor PC/LR after receiving the DREG_REQ message. The present invention specifies the process of a MSS entering the idle mode initiated by the network and the settings of relevant parameters, thus enhancing the stability of the process of entering the idle mode and saving the system resources.
