Solution Overview

Problem

In public places like shopping malls, deploying multiple positioning base stations to push location-specific information to terminals leads to high spectrum resource consumption and server load due to each terminal needing to maintain independent connections and the server processing numerous requests.

Innovation Solution

A method where terminals determine a target positioning base station, listen to a broadcast data stream from an access device that includes information for multiple base stations, and extract relevant data without directly requesting the server, reducing spectrum usage and server load by processing requests independently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple positioning base stations are deployed to push location-specific information to terminals, then location-based service capability is improved, but spectrum resource consumption increases

Engineering Contradiction:
Improvelocation-based service capabilityVSAvoidspectrum resource consumption
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges the functions of multiple positioning base stations into a single base station. The merged base station receives positioning information from multiple locations and broadcasts integrated positioning data to terminals, eliminating the need for multiple independent base stations and reducing spectrum resource consumption while maintaining location-based service capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single positioning base station is designed with multi-functionality to serve multiple location areas. It can broadcast positioning information for multiple different locations simultaneously, making one base station universal enough to replace multiple specialized base stations, thereby reducing overall spectrum usage

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If each terminal maintains independent connection to request information from server, then information accuracy is improved, but server load increases

Engineering Contradiction:
Improveinformation accuracyVSAvoidserver load
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The base station performs preliminary action by pre-acquiring and integrating positioning information from multiple base stations before terminals request data. This advance preparation allows the base station to broadcast ready-to-use positioning data, eliminating the need for terminals to individually query the server and reducing server load while maintaining information accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The positioning base station acts as an intermediary between the server and terminals. It receives positioning data from the server and multiple base stations, processes this information, and broadcasts it to terminals. This intermediary role prevents direct terminal-server connections for positioning requests, significantly reducing server load while ensuring accurate positioning information delivery

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A data pushing method and a related apparatus are provided. The data pushing method includes: obtaining, by a terminal, a target identifier of a target positioning base station; obtaining, by the terminal, a broadcast data stream delivered by an access device, where the broadcast data stream includes information data corresponding to identifiers of multiple positioning base stations; and extracting, by the terminal from the broadcast data stream, target information data corresponding to the target identifier. According to the present invention, spectrum resources are reduced, and server load is lightened.
