Wireless Access Point Code-Division Multiplexing for UE Scalability

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless telecommunications networks face scalability issues in managing a large number of User Equipment (UE) devices, particularly due to the inefficiencies in transmitting instructions to multiple UEs over radio resources.

Innovation Solution

A method is introduced where each User Equipment device is allocated an item of information, encoded using code-division multiplexing to produce a signal string, and a network identifier is derived from this signal string. This network identifier is broadcast by the Wireless Access Point, allowing each UE to retrieve and demultiplex the signal string to obtain its specific information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If instructions are transmitted serially to each UE via WLAN, then each UE can receive its instructions, but the network management scalability deteriorates as the number of UEs increases

Engineering Contradiction:

Improvenetwork management efficiencyVSAvoidtransmission time for multiple UEs

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent combines multiple individual instruction transmissions into a single aggregated transmission. The Device Management System collects instructions for multiple UEs, encodes them together with unique identifiers, and transmits them simultaneously over the WLAN. This merging of transmissions directly resolves the scalability issue by eliminating the linear time increase that would otherwise occur with serial transmissions to each UE.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the aggregated instruction stream into individual UE-specific instructions using unique identifiers. Each instruction is tagged with a specific UE identifier, allowing UEs to extract and process only their designated instructions from the combined transmission. This segmentation enables parallel processing of multiple instructions without requiring separate transmission channels, thus improving scalability while maintaining individual UE addressability.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If serial transmission is used to communicate instructions to multiple UEs, then radio resources are allocated, but the resource usage efficiency deteriorates with increasing UE count

Engineering Contradiction:

Improvenumber of instructions transmittedVSAvoidradio resource consumption

Core Design Contradiction:

Quantity of substanceVSLoss of energy

Solution Approach 1:

The patent merges multiple instruction transmissions into a single radio transmission event. Instead of allocating separate radio resources for each UE instruction, the system transmits all instructions in one aggregated message over the WLAN. This significantly reduces radio resource consumption and energy usage, as the radio interface is activated only once rather than multiple times for serial transmissions.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the WAP broadcasts network identifier derived from signal string, then UEs can identify and connect to WLAN, but the complexity of information encoding increases

Engineering Contradiction:

ImproveUE connection to WLANVSAvoidencoding and decoding process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent makes the network identifier serve multiple functions simultaneously. It acts as both the traditional WLAN identification signal for UE connection and as an encoded carrier of instruction data. By embedding instruction information within the network identifier structure, the system eliminates the need for separate connection and data transmission phases, reducing overall system complexity despite the encoding requirement.

Inventive Principle:

Principle #6Universality (Multi-functionality)
