Call Hibernation Method for Telecommunication Resource Release

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional telecommunication systems waste resources and incur unnecessary costs when calls are placed on hold, as resources are maintained even though they are not being utilized for communication, leading to wastage of airtime and money.

Innovation Solution

A call hibernation method where resources allocated to a call are released upon a hibernate message from the called party, with reestablishment information stored for later use when the call is resumed, allowing the network to free up resources and avoid billing for the inactive call period.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If resources are maintained during a call hold state, then the call can be quickly resumed, but resources are wasted and costs increase

Engineering Contradiction:

Improvecall resumption capabilityVSAvoidresource wastage

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts the essential call information (reestablishment information) from the full call state and stores only this critical data in the network. When a call is placed on hold, the complete call resources are released, but the reestablishment information is preserved. This allows the call to be resumed by retrieving and using this stored information, achieving both resource efficiency and reliable call resumption.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary action by storing reestablishment information in the network before the call is actually terminated or fully released. This pre-stored information contains all necessary details to quickly reestablish the call connection, eliminating the need to maintain full call resources during hold periods while ensuring rapid call resumption is possible.

Inventive Principle:

Principle #10Preliminary action

2Duration of action of moving object

If resources are maintained during a call hold state, then communication can be quickly restored, but billing costs increase for unused resources

Engineering Contradiction:

Improvecall restoration speedVSAvoidbilling time

Core Design Contradiction:

Duration of action of moving objectVSLoss of time

Solution Approach 1:

The patent separates the billing-relevant call state from the resource-intensive call connection. Only the essential reestablishment information is maintained in the network, which is sufficient for both billing purposes and call restoration. This extraction allows the system to stop billing for hold periods while maintaining the ability to quickly restore communication.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary action by pre-storing reestablishment information that contains all necessary call details. This allows the network to quickly restore calls without needing to maintain resources during hold periods, thereby reducing billing time for unused resources while ensuring rapid call restoration when needed.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If resources are released during a call hold state, then resource efficiency improves, but call reestablishment complexity increases

Engineering Contradiction:

Improvenetwork resource efficiencyVSAvoidcall reestablishment process

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts and stores only the critical reestablishment information in the network while releasing all other call resources. This extracted information serves as a compact representation that simplifies the reestablishment process despite resources being released. The network uses this pre-stored information to efficiently restore calls without complex procedures.

Inventive Principle:

Principle #2Taking out (Extraction)

4Loss of energy

If resources are released during a call hold state, then cost efficiency improves, but airtime accounting accuracy must be maintained

Engineering Contradiction:

Improvecost efficiencyVSAvoidairtime billing accuracy

Core Design Contradiction:

Loss of energyVSMeasurement precision

Solution Approach 1:

The patent extracts and preserves only the billing-relevant reestablishment information in the network while releasing all resource-intensive call components. This extracted information is sufficient for both cost efficiency (by allowing resource release) and measurement precision (by maintaining accurate call state data for billing purposes). The network can accurately account for airtime based on this stored information.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A call hibernation method may include releasing resources allocated to a first call between a calling party and a called party in response to a hibernate message from the called party. The hibernate message may indicate to hibernate the first call, and/or the hibernate message may include reestablishment information for reestablishing communication between the calling party and the called party. A second call may be established between the calling party and the called party in response to a deactivate-hibernated message from the called party. The deactivate-hibernated message may indicate the called party desires to reestablish communication with the calling party, and/or the deactivate-hibernated message may include at least a portion of the reestablishment information.
