Solution Overview

Problem

Current wireless communication networks face inefficiencies in handling signalling procedures due to the static allocation of processing modules for wireless devices, making it difficult to load share and scale processing resources effectively.

Innovation Solution

The introduction of a Temporary Routing ID (TRID) system allows for dynamic allocation of processing modules by assigning a TRID valid for a defined interval, enabling flexible routing and efficient handling of signalling procedures across network nodes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If processing modules are statically allocated to wireless devices, then reliability of signalling handling is improved, but adaptability and scalability deteriorate

Engineering Contradiction:

Improvesignalling handling reliabilityVSAvoidprocessing module adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a TRID (Temporary Routing Identifier) as an intermediary that decouples the wireless device context from permanent processing module assignment. The TRID acts as a temporary mediator that routes signalling to the appropriate processing module during a defined interval, allowing flexible reassignment while maintaining reliable context delivery.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic allocation of processing modules by making the TRID valid only for a defined interval. This temporal dynamicity allows processing modules to be reassigned to different wireless devices after the interval expires, enabling load sharing and scaling while maintaining reliable signalling handling within each interval.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If processing modules are statically allocated, then signalling procedure stability is improved, but load sharing capability deteriorates

Engineering Contradiction:

Improvesignalling procedure stabilityVSAvoidload sharing capability

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent implements periodic reassignment of processing modules by making TRIDs valid for defined intervals. Within each interval, the processing module assignment remains stable, but periodically the TRIDs can be reassigned to different modules, enabling load sharing while maintaining stability during each operational period.

Inventive Principle:

Principle #19Periodic action

3Measurement precision

If permanent routing identifiers are used, then context routing accuracy is improved, but system scalability deteriorates

Engineering Contradiction:

Improvecontext routing accuracyVSAvoidsystem scalability

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent uses temporary, short-lived TRIDs instead of permanent routing identifiers. Each TRID is valid only for a defined interval and can be discarded and reassigned, enabling scalable system operation while maintaining accurate context routing within each interval through the temporary identifier.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

Embodiments herein relate to a method performed in a first network node for handling one or more signaling procedures of a wireless device in a wireless communication network. The first network node, receiving a first message from a second network node indicating an initiation of a signaling procedure for the wireless device; selecting a processing module for handling the signaling procedure; retrieving context of the wireless device; storing the retrieved context on the selected processing module; assigning a TRID to the signaling procedure, pointing to the selected processing module, which TRID being valid for an interval; and transmitting a second message to the second network node and/or another network node, which second message is associated with the signaling procedure and comprises the assigned TRID.
