Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional P2MP systems in G.MGfast networks incur unnecessary resource overheads and power consumption due to the network device periodically indicating uplink random access windows, especially when few users are online and registration probability is low.

Innovation Solution

The network device receives indication information from the terminal device to determine when to send uplink registration windows, reducing unnecessary indications and conserving resources by using different frequency bands and forms for indication signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network device periodically sends uplink random access indication signals to users, then newly-online users can perform registration, but unnecessary resource overheads and power consumption are caused

Engineering Contradiction:

Improveuser registration capabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies periodic action by having the network device send uplink random access indication signals at regular intervals during specific time windows (e.g., registration windows). This allows the system to maintain reliable user registration capability while limiting the frequency of signaling transmissions, thereby reducing unnecessary power consumption and resource overhead when no users need to register.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent implements self-service by enabling terminal devices to autonomously determine when to initiate registration procedures based on local conditions (e.g., when a user connects). The network device responds to registration requests rather than continuously polling, allowing the system to maintain reliability while minimizing unnecessary signaling and energy consumption.

Inventive Principle:

Principle #25Self-service

2Reliability

If the network device periodically sends uplink random access indication signals to users, then newly-online users can perform registration, but unnecessary resource overheads are caused

Engineering Contradiction:

Improveuser registration capabilityVSAvoidresource overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The network device transmits uplink random access indication signals periodically within defined time windows rather than continuously. This periodic transmission maintains the ability to support user registration while significantly reducing the quantity of signaling resources consumed, as signals are only sent when registration opportunities arise.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses partial action by sending indication signals only when necessary (during registration windows or in response to registration requests) rather than maintaining continuous signaling. This ensures user registration capability is preserved while avoiding excessive resource overhead from unnecessary transmissions.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If the network device continuously monitors for user registration requests, then all registration attempts can be detected, but power consumption increases

Engineering Contradiction:

Improveregistration detection accuracyVSAvoidnetwork device power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The network device monitors for registration requests periodically during specific time windows rather than continuously. This periodic monitoring maintains reliable detection of registration attempts while significantly reducing power consumption by allowing the device to enter low-power states between monitoring intervals.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

Terminal devices are empowered to autonomously initiate registration procedures and notify the network device when appropriate. This self-service approach allows the network device to reduce its monitoring activity and power consumption while still reliably detecting and responding to registration requests through event-driven architecture.

Inventive Principle:

Principle #25Self-service

AI summary

This application provides an uplink access method and a device. The method includes: a network device receives indication information sent by a terminal device when the terminal device goes online, where the indication information is used to trigger the network device to send uplink registration window indication information on a first port; the uplink registration window indication information indicates a registration window location at which the terminal device sends uplink registration information; and the network device sends the uplink registration window indication information on the first port according to the indication information. According to the technical solutions provided in embodiments of this application, in a P2MP working mode, a network device may be prevented from periodically indicating a registration window, thereby reducing resource overheads and power consumption.
