User Equipment Cellular Transceiver State Switching

Solution Overview

Problem

Users often keep cellular radio transceivers enabled continuously to receive calls, leading to increased power consumption and network resource provisioning, especially since many premises lack femtocell base stations.

Innovation Solution

A method and apparatus that allow a user equipment to switch its cellular radio transceiver between a low-power state and an active state based on detected communication requests via a secondary network interface, such as WiFi or a fixed line, enabling communication without continuous camping on the cellular network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cellular radio transceiver is kept enabled continuously to receive calls, then the user can receive communications at any time, but the power consumption and network resource provisioning increase

Engineering Contradiction:

Improveavailability of communication receptionVSAvoidpower consumption of transceiver

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary registration with the cellular network before communication is needed. The transceiver is pre-configured with network parameters and registered in advance, so when communication is required, the device can quickly activate without full network re-attachment procedures, reducing both power consumption and activation time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The transceiver dynamically switches between different operational states (disabled, idle mode, connected mode) based on communication requirements. The device transitions from a fully disabled low-power state to active communication states only when needed, optimizing the balance between power consumption and communication availability.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the user equipment is continuously camped on the cellular wireless network, then the user can receive calls and messages, but the network provisioning must support a large number of active user equipments

Engineering Contradiction:

Improveavailability of communication receptionVSAvoidnumber of active user equipments on network

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system performs preliminary registration with the cellular network before communication is needed. The transceiver is pre-configured with network parameters and registered in advance, so when communication is required, the device can quickly activate without full network re-attachment procedures, reducing both power consumption and activation time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention extracts the essential network access functionality from continuous network camping. By using idle mode with periodic updates and fast re-attachment capabilities, the device separates the need for network availability from the need for continuous active connection, allowing network resources to be reduced while maintaining service availability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Use of energy by moving object

If the cellular radio transceiver is disabled to reduce power consumption, then the power consumption decreases, but the user cannot receive calls unless the transceiver is enabled

Engineering Contradiction:

AI summary

User apparatus 2 in a cellular wireless network 14 comprises a user equipment 4 having a first network interface 6 comprising a radio transceiver 8 for communicating via the cellular wireless network 14. The radio transceiver 8 may be set to a first state or to a second state. The user apparatus 2 has a second network interface 10 to a second network 16. A call to the user apparatus 2 is handled by detecting, via the second network interface 10, a request to receive a communication and dependent on the detection of the request via the second network interface 10, switching the radio transceiver 8 to the second state. The communication is then received at the user equipment 4 via the radio transceiver 8. As a result, the user equipment may receive the communication via the cellular wireless network without the need for the user equipment to be continuously camped on the cellular wireless network, so that the cellular wireless network may reduce provisioning of network resources and so reduce power consumption.
