Solution Overview

Problem

Multi-mode wireless access terminals face battery consumption issues when operating in high data rate networks, as they often need to remain active for extended periods, even when not actively using the network, leading to inefficient battery usage and increased power consumption.

Innovation Solution

A multi-network wireless communications system that allows a terminal to register in a first network and obtain access information for a second network only when needed, enabling seamless switching between paging-optimized and high data rate networks, with the first network providing necessary access information for the second network, thereby minimizing battery consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a multi-mode AT camps on a high data rate network, then data service access is improved, but battery consumption increases

Engineering Contradiction:
Improvedata service accessVSAvoidbattery consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system segments network functionality by separating paging operations (handled by paging-optimized network) from data transfer operations (handled by high data rate network). The AT maintains minimal connectivity in the paging network for low-power operation while establishing full connectivity only in the high data rate network when actual data transfer is needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The AT dynamically switches between networking modes based on operational requirements. It camps on the paging-optimized network during idle periods for minimal power consumption, and transitions to the high data rate network when data services are required, optimizing the balance between productivity and energy consumption.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If a multi-mode AT camps on a paging-optimized network, then battery consumption is reduced, but data service access is limited

Engineering Contradiction:
Improvebattery consumptionVSAvoiddata service access
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The paging-optimized network acts as an intermediary that enables the AT to access the high data rate network without directly camping on it. The AT receives paging messages and access information through the low-power paging network, which then facilitates connection to the high data rate network only when data services are actually needed.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by having the AT camp on the paging-optimized network first, where it can receive paging messages and access information in advance. This preliminary connection enables rapid transition to the high data rate network when data services are required, without requiring continuous monitoring of the high data rate network.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If overlapping networks cooperate with the paging-optimized network providing high data rate network access information, then network efficiency is improved, but system complexity increases

Engineering Contradiction:
Improvenetwork efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The paging-optimized network is enhanced with multi-functionality, serving both its traditional paging role and the additional role of providing access information for the high data rate network. This universal approach allows a single network infrastructure to support multiple functions, reducing the need for separate dedicated systems.

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

AI summary

A system and method are provided for a multi-network wireless communications access terminal (AT) to access multi-network coverage. The method registers a multi-network AT in a first communications network. In response to registering with the first network, the AT receives information via the first network that is required for accessing a second communications network (e.g., an IEEE 802.20 or 1xEV-DO network). The AT obtains services accessed via the second network, in response to the access information received via the first network. For example, the second network access information may be system information, channel information, or access point parameters. The AT retains the option of obtaining services accessed via the first network if the second network cannot be accessing the second network.
