Solution Overview

Problem

IP telephony networks face inefficiencies in utilizing SIP trunk group capacity due to dedicated allocation, leading to idle channels and challenges in sharing resources among enterprises while ensuring individual capacity guarantees and managing channel allocation across diverse network devices.

Innovation Solution

A system and method for configuring shared SIP trunk groups, allowing reserved capacity for individual enterprises while sharing excess capacity with other enterprises, using a centralized tool to manage and allocate communication resources dynamically, ensuring guaranteed availability and efficient utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a SIP trunk group is dedicated to a particular enterprise system, then the enterprise system has guaranteed capacity availability, but significant portions of the SIP trunk group capacity remain unused

Engineering Contradiction:

Improvecapacity guaranteeVSAvoididle channel capacity

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent segments the SIP trunk group capacity into two distinct portions: a reserved portion dedicated to a specific enterprise system for guaranteed capacity, and a shared portion available to multiple enterprises. This segmentation allows the system to simultaneously provide capacity guarantees to individual enterprises while enabling other enterprises to utilize the previously idle shared capacity, thereby reducing overall idle channels.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements multi-functionality by allowing the same SIP trunk group to serve dual purposes: providing guaranteed capacity to a specific enterprise system through the reserved portion, and simultaneously serving as a shared resource for multiple enterprises through the shared portion. This universal utilization of the trunk group capacity resolves the contradiction between dedicated guarantee and efficient resource utilization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of energy

If a SIP trunk group is shared among multiple enterprises, then resource utilization increases, but calling resources may be in use by other systems when a user attempts to establish a session

Engineering Contradiction:

Improveidle channel capacityVSAvoidsession establishment guarantee

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

By segmenting the SIP trunk group into reserved and shared portions, the patent ensures that the reserved portion remains exclusively available to the specific enterprise system, guaranteeing session establishment capability. The shared portion can be utilized by multiple enterprises, increasing overall resource utilization without compromising the reliability of the reserved capacity for any individual enterprise.

Inventive Principle:

Principle #1Segmentation

3Reliability

If dedicated circuits are allocated to each enterprise system, then individual capacity guarantees are ensured, but network resource utilization decreases

Engineering Contradiction:

Improveindividual capacity guaranteeVSAvoidnetwork resource utilization

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies segmentation by dividing the network resource pool into reserved resources allocated to individual enterprises for guaranteed capacity, and shared resources available to multiple enterprises. This approach maintains individual capacity guarantees through the reserved portion while significantly improving overall network resource utilization through the shared portion, resolving the contradiction between reliability and productivity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent merges the previously separate dedicated resource allocations into a unified shared resource pool, where individual enterprises retain guaranteed access to their reserved portion while gaining access to additional shared resources when available. This combining approach improves network resource utilization while maintaining individual capacity guarantees.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

System and methods are disclosed for configuring the sharing of resource pools and individual resources in the resource groups among enterprise communication systems. In certain embodiments, the resource pools are trunk groups and the individual resources that comprise the trunk groups are communication resources. Digital PBXs components associated with different enterprise communication systems are registered and assigned shared use of a trunk group. Communication services are provided to the digital PBXs using the channels of the shared trunk group. Each enterprise may reserve channels within the trunk group for exclusive use by the enterprise, while sharing use of other channels in the trunk group. Each enterprise can be guaranteed a minimum calling capacity while providing improved resource utilization due to fewer idle communication channels.
