Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication protocols between host units and modem units in wireless communication systems often get blocked by large data transfers, preventing effective transfer of control and status information.

Innovation Solution

A host interface protocol that multiplexes data signals with control and status signals using a message header with a length field and a message ID field, allowing for separate control and status protocol transfers within an optional payload field, enabling efficient transfer of control and status messages alongside data.

1Productivity

If data signals are transmitted between host unit and modem unit, then data transfer capability is improved, but control and status information transfer is blocked

Engineering Contradiction:

Improvedata transfer capabilityVSAvoidcontrol and status information transfer

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The communication interface is segmented into two distinct protocols: a data protocol for bulk data transfers and a control and status protocol for management information. This segmentation allows both data and control signals to be transmitted simultaneously over the same physical interface without interference, resolving the blocking issue while maintaining high data transfer capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A protocol multiplexer acts as an intermediary that receives both data signals and control/status signals, separates them based on their protocol type, and routes them appropriately. This mediator enables simultaneous transmission of both signal types without mutual blocking, improving both productivity and reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If separate control and status protocol is used, then control and status information transfer is improved, but protocol complexity increases

Engineering Contradiction:

Improvecontrol and status information transferVSAvoidprotocol structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

While maintaining separate protocol logic, both the data protocol and control/status protocol share common physical transmission infrastructure and protocol multiplexing mechanisms. This merging of physical layer resources reduces overall system complexity compared to having completely separate physical interfaces, while still providing reliable control and status information transfer

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A host interface protocol and a control and status protocol for use with host unit and a wireless communication unit are described. The host interface protocol allows for multiplexing between data transfer messages and control and status messages. In a preferred embodiment, the control and status message protocol supports messages that can be a message payload of a host interface protocol payload.
