Solution Overview

Problem

Current broadband service technologies face issues with service nesting, where subsequent terminating call services disrupt the normal operation of preceding services like conference calls and wake-up calls, leading to mutual impacts and ineffective solutions in prior art.

Innovation Solution

A broadband service nesting processing method and device that identifies service nesting between terminating call services and current services through a service identity in the service request message, evading the terminating call service to prevent disruptions, specifically by refusing to play hold tones during conference calls and avoiding call transfer services during wake-up calls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If terminating call services (call hold, call transfer) are implemented, then users can access call management features, but preceding services (conference call, wake-up call) are disrupted

Engineering Contradiction:
Improvecall service featuresVSAvoidservice operation stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by checking whether a user is currently engaged in a preceding service (conference call or wake-up call) before allowing terminating call services to be initiated. The system performs this check in advance by examining ongoing service states, and if a conflict is detected, it prevents the terminating call service from being executed, thereby avoiding disruption to the preceding service while still allowing call management features to be accessed when safe.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If service nesting is allowed, then multiple services can operate concurrently, but service conflicts and disruptions occur

Engineering Contradiction:
Improveservice concurrencyVSAvoidservice mutual impact
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary mechanism in the form of a service state checking module that acts as a mediator between preceding services and terminating call services. This intermediary checks the current service state before allowing service nesting, and if a conflict is detected, it blocks the terminating service from interfering with the preceding service. This intermediary layer enables controlled service concurrency while preventing harmful mutual impacts between services.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention provides a broadband service nesting processing method and device, and a service application server. The method includes: receiving a service request message sent to a user equipment, and obtaining a service identity of a current service carried in the service request message; determining that service nesting is formed between a terminating call service and a service corresponding to the service identity of the current service; and evading the terminating call service according to a result of the service nesting formed between the terminating call service and the service corresponding to the service identity. A technical solution provided in an embodiment of the present invention can effectively avoid the occurrence of service nesting phenomena.
