Solution Overview

Problem

Current emergency broadcast message systems in mobile networks require significant effort from network function (NF) consumers to discover and select target NF producers, which can be inefficient and resource-intensive.

Innovation Solution

The proposed emergency message broadcasting framework utilizes a service communication proxy (SCP) to perform discovery and selection of Access & Mobility Management Function (AMF) instances on behalf of the Cell Broadcast Center Function (CBCF), reducing the workload of NF consumers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If direct communication models are used for emergency broadcast messages, then the NF consumer can directly discover and select target NF producers, but the NF consumer must perform significant discovery and selection work which increases resource consumption and complexity

Engineering Contradiction:

Improveemergency message deliveryVSAvoiddiscovery and selection workload

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a Service Communication Proxy (SCP) as an intermediary between the NF consumer (CBCF) and NF producers (AMF instances). The SCP performs the discovery and selection of target AMF instances on behalf of the CBCF, eliminating the need for the CBCF to directly interact with the NRF or perform complex discovery procedures. This mediator approach resolves the contradiction by maintaining reliable message delivery while significantly reducing the complexity and resource consumption of the NF consumer.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the NF consumer performs discovery and selection of NF producers, then direct communication can be established, but the process consumes significant time and resources for the NF consumer

Engineering Contradiction:

Improvemessage broadcasting efficiencyVSAvoiddiscovery and selection time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The Service Communication Proxy (SCP) performs discovery and selection of AMF instances in advance, maintaining updated information about available NF producers. When the CBCF needs to broadcast an emergency message, the SCP already has the necessary routing information ready, eliminating the need for real-time discovery and selection. This preliminary action resolves the contradiction by enabling efficient message broadcasting while minimizing the time and resources consumed by the NF consumer.

Inventive Principle:

AI summary

According to disclosed embodiments, as discussed below, a cell broadcasting framework is provided including receiving a request from a Network Function (NF) consumer by a service communication proxy (SCP) on a network, the request including a set of parameters, identifying a plurality of target NF producers corresponding to the set of parameters, transmitting the request to the plurality of target NF producers, receiving a plurality of successful request responses corresponding to some or all of the plurality of target NF producers, transmitting one of the plurality of successful request response to the NF consumer, and discarding all other successful request responses.
