1Reliability

If data is transferred via the applications processor between Bluetooth and Wi-Fi networks, then protocol conversion and network stack processing can be performed, but latency increases and processor loading rises

Engineering Contradiction:

Improvenetwork communication reliabilityVSAvoidcommunication latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the network stack functionality from the applications processor and implements it directly on the wireless communications chip. This allows Bluetooth data to be converted to Wi-Fi packets without involving the applications processor, thereby eliminating the latency associated with chip-to-chip data transfers while maintaining reliable protocol conversion

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an offload agent as an intermediary component on the wireless communications chip that handles network stack operations. This offload agent acts as a mediator between Bluetooth and Wi-Fi protocols, performing packet generation and network processing functions that would otherwise require applications processor involvement

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If data is transferred via the applications processor between Bluetooth and Wi-Fi networks, then comprehensive network processing can be performed, but power consumption increases

Engineering Contradiction:

Improvenetwork processing capabilityVSAvoidprocessor power consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts network stack processing functions from the applications processor and relocates them to the wireless communications chip. This extraction eliminates the need for high-power applications processor involvement in routine network operations, significantly reducing power consumption while preserving full network processing capability through the offload agent

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The wireless communications chip performs network stack operations independently through the offload agent, serving its own network processing needs without requiring applications processor assistance. This self-service capability allows the chip to handle Bluetooth-to-Wi-Fi conversion autonomously, reducing overall system power consumption

Inventive Principle:

Principle #25Self-service

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent merges the network stack functionality with the wireless communications chip, combining protocol conversion capabilities directly into the chip that handles both Bluetooth and Wi-Fi interfaces. This integration eliminates the need for separate chip-to-chip data transfer steps, enabling direct internal processing and significantly improving data transfer speed

Inventive Principle:

AI summary

Low latency network communication paths are provided. A method includes identifying, by an agent of a first portion of a device, that a Bluetooth controller is being used with the device, the Bluetooth controller to provide input via a second portion of the device for an application being communicated to the device from a server via a network stack of the first portion. The method includes establishing, by the agent and responsive to the identification, the offload agent on the second portion to route data received via Bluetooth to communicate, via Wi-Fi, to the server and bypassing the first portion of the device. The method includes communicating, by the second portion (e.g., the offload agent), one or more packets generated by the second processor to the server, the one or more packets including the data received from the Bluetooth controller.
