Solution Overview

Problem

Existing communication systems in mobile objects require multiple access point names (APNs) and line contracts to handle increasing numbers of services, leading to inefficiencies.

Innovation Solution

A communication controller that allocates multiple local IP addresses to different services within a mobile object and maps them to a single access point name for external communication, using a connection table to manage IP address groups and access point names based on location and service type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple APNs are allocated to handle increasing numbers of services, then service capability is improved, but the number of line contracts and system complexity increases

Engineering Contradiction:

Improveservice capabilityVSAvoidnumber of APNs and line contracts

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single wireless communication device is configured to handle multiple APNs and multiple local IP addresses, making it capable of serving multiple services through one unified interface. This multi-functional approach allows the system to support diverse services without proportionally increasing the number of physical communication devices or line contracts.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a communication controller as an intermediary component that manages the mapping between local IP addresses and APNs. This mediator handles the complexity of routing and APN selection internally, shielding other system components from the complexity while enabling multiple services through a standardized interface.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple APNs are used for different services, then service differentiation is improved, but communication management complexity increases

Engineering Contradiction:

Improveservice differentiationVSAvoidcommunication management

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The communication controller automatically performs APN selection and routing based on pre-configured mapping rules between local IP addresses and APNs. The system self-manages the complexity of communication routing without requiring manual intervention, maintaining ease of operation while supporting service differentiation through automated intelligent routing.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses configurable mapping parameters (local IP address to APN associations) to enable flexible service differentiation. By changing these parameter mappings, different services can be routed to appropriate APNs without modifying the underlying system architecture or requiring complex manual configuration changes.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If one-to-one mapping between services and APNs is maintained, then service reliability is improved, but cost efficiency deteriorates

Engineering Contradiction:

Improveservice reliabilityVSAvoidnumber of line contracts

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Multiple services that can share common communication requirements are merged into a single APN group through the local IP address mapping mechanism. This consolidation reduces the total number of line contracts needed while maintaining reliable communication by grouping services with similar reliability requirements under the same APN.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

A single line contract associated with an APN serves multiple services simultaneously through the many-to-one mapping relationship. This multi-functional use of line contracts reduces the total quantity of line contracts required while maintaining service reliability through the wireless communication device's ability to handle multiple IP addresses and routing scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A communication controller is a device which controls communication between an electronic device of a mobile object and an external device, and includes: a wireless communication device configured to communicate with the external device respectively via an external communication network; a reception unit configured to receive communication data including a transmission source local IP address from the electronic device; and a route control unit configured to input the received communication data to the wireless communication device based on the transmission source local IP address. The route control unit makes each address group including one or more transmission source local IP addresses correspond to one access point name and inputs the communication data to the wireless communication device.
