/check-network-quality endpoint – purpose and data format

[FredericFi]

Hello all + @bigludo7,

On Orange side, we are building a prototype using ConnectivityInsights (and CSON APIs to retrieve mobile cell data).
As we didn’t attend the previous specification meetings, we would like to clarify the API objectives and share some proposals to support certain use cases.

• Currently, it returns plain text indicators. Could you clarify its intended purpose?
• Since the API aims to show how confident the network is in meeting a given demand, would it be possible to return confidence values (e.g., on a scale from 1 to 5)?
• Could there also be an option to provide more detailed data if needed?

We look forward to your thoughts on these points and plan to attend the next Working Group meeting to discuss them further.

Hi @FredericFi and welcome :) Good to hear you are building a prototype, I think that can provide valuable input!

The answer to all the questions above is that we will aim to provide a more precise/unambiguous response than plain text. For now, we have plain text as a starting point until we can agree a consistent metric/methodology.

There is a methodology being discussed in IETF, 'Quality of Outcome', which is based on a mathematical model called Quality Attenuation. The result is a CDF which provides a percentage likelihood of the application demands (and hence customer expectation) being met by the network. That seems to be the ideal response to give to a consumer of this API.

PS what is a 'CSON API to retrieve mobile cell data'? That sounds useful!

Hi @Kevsy,

Thanks for the link to IETF.

A CSON API is an interface used to retrieve mobile cell data from a Centralized Self-Organizing Network, which manages and optimizes cellular network operations centrally. It provides information such as cell IDs, locations, signal metrics, and network configuration and monitoring. We are currently testing the possibilities provided by such an API.
