Mobile Terminal Beacon Channel Resource Allocation

Solution Overview

Problem

In current cellular systems, mobile terminals with poor channel quality, especially those in coverage holes or with damaged base stations, face challenges in accessing the network due to limited beacon channel resources, leading to inefficient use and potential waste of these resources.

Innovation Solution

A network accessing method for mobile terminals, where a mobile terminal sends a beacon channel on a resource allocated by the base station and broadcasts an access signal on a corresponding broadcast channel, allowing it to assist other terminals in accessing the network, thereby optimizing the use of beacon and access resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile terminals autonomously discover each other by checking beacon channels, then mobile terminals can potentially assist each other in accessing the network, but beacon channel resources are wasted when terminals send beacons without establishing connections

Engineering Contradiction:

Improvenetwork accessibility for terminals in coverage holesVSAvoidbeacon channel resource waste

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The base station performs preliminary actions by allocating dedicated beacon channel resources and broadcast channel resources before terminal discovery begins. This pre-allocation ensures that terminals know exactly when and where to transmit beacons and listen for responses, preventing resource waste while enabling autonomous discovery functionality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The base station acts as an intermediary that coordinates between access terminals and base-station terminals. It allocates resources and manages the discovery process, allowing terminals to assist each other without directly wasting beacon channel resources on unsuccessful transmissions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If mobile terminals send beacons on limited beacon channel resources, then terminal discovery is enabled, but the limited resources lead to inefficient use and potential waste

Engineering Contradiction:

Improveautonomous terminal discoveryVSAvoidbeacon channel resource utilization efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The base station performs preliminary actions by allocating dedicated beacon channel resources and broadcast channel resources before terminal discovery begins. This pre-allocation ensures that terminals know exactly when and where to transmit beacons and listen for responses, preventing resource waste while enabling autonomous discovery functionality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback mechanisms where the base station monitors beacon channel usage and adjusts resource allocation accordingly. This feedback loop allows the base station to optimize resource distribution and prevent waste while maintaining autonomous discovery capabilities.

Inventive Principle:

Principle #23Feedback

3Extent of automation

If access terminals need to discover base-station terminals autonomously, then network accessibility is achieved without central coordination, but the distributed manner causes beacon channel waste when terminals don't establish connections

Engineering Contradiction:

Improveautonomous terminal discoveryVSAvoidbeacon channel resource waste

Core Design Contradiction:

Extent of automationVSLoss of substance

Solution Approach 1:

The base station performs preliminary actions by allocating dedicated beacon channel resources and broadcast channel resources before terminal discovery begins.

AI summary

The present invention discloses a network accessing method for a mobile terminal, and a mobile terminal. In some feasible implementation manners of the present invention, a mobile terminal reads a help request used for accessing a network by another mobile terminal; sends a beacon channel on a beacon channel resource allocated by a base station of the network, and sends a broadcast signal on a broadcast channel resource corresponding to the beacon channel resource, where the broadcast signal includes an access resource; and receives an access request of the another mobile terminal on the access resource, and assists the another mobile terminal in accessing the network. According to the network accessing method for a mobile terminal, and the mobile terminal, the beacon channel is sent on the beacon channel resource allocated by the base station of the network, and the broadcast signal is sent on the broadcast channel resource corresponding to the beacon channel resource, to indicate the access resource, so that another mobile terminal connects to the mobile terminal on the access resource and then accesses the network, which avoids a waste of the beacon channel and more properly uses the beacon channel and the access resource.
