		# How to develop an ETSI MEC application to exploit both ETSI MEC and oneM2M platforms
		This tutorial introduces the step by step procedure to create a basic MEC application following ETSI MEC standards and oneM2M standards to manage devices/sensors/actuators...
		It uses the ETSI MEC Sandbox simulator.
		It uses the ETSI MEC Sandbox.

		<div class="alert alert-block alert-danger">
		<b>Note:</b> These source code examples are simplified and ignore return codes and error checks to a large extent. We do this to highlight how to use the MEC Sandbox API and the different MEC satndards and reduce unrelated code.
		A real-world application will of course properly check every return value and exit correctly at the first serious error.
		</div>

		%% Cell type:markdown id: tags:

		Here is the list of the questions and topics to clarify from the ETSI MEC perspective to support an efficient support of oneM2M features
		<div class="alert alert-block alert-danger">
		<b>Note:</b> How to name oneM2M sensors and devices?

		## What is a ETSI MEC application

		For more details on how to develop an ETSI MEC application, please refer to [The Wiki MEC web site](https://www.etsi.org/technologies/multi-access-edge-computing) and the [ETSI MEC Tutoral](http://mec-platform2.etsi.org:9999/notebooks/work/notebook/MEC%20application.ipynb).

		## The basics to develop an ETSI MEC application

		All the code below are helpers functions required to start the development our MEC application.

		<b>Note:</b> The sub-paragraph 'Putting everything together' is a specific paragraph where all the newly features introduced in the main paragraph are put together to create an executable block of code. It is possible to skip this block of code by removing the comment character (#) on first line of this block of code.

		## Create our fourth MEC application: how to use V2X QoS Prediction

		The MEC Sanbox V2X QoS Prediction is based on a grid Map of Monaco City where areas are categorized into residential, commercial and coastal.
		PoAs (Point Of Access) are categorized depending on where they lie in each grid.
		Each category has its own traffic load patterns which are pre-determin. The V2X QoS Prediction) will give more accurate values of RSRP and RSRQ based on the diurnal traffic patterns for each. The network scenario named "4g-5g-v2x-macro" must be used to get access to the V2X QoS Prediction feature.

		Note: The MEC Sanbox V2X QoS Prediction is enabled when the PredictedQos.routes.routeInfo.time attribute is present in the request (see ETSI GS MEC 030 V3.2.1 (2024-02) Clause 6.2.6 Type: Preditecd QoS)

		Limitations:
		* The Location Granularity is currently not being validated as RSRP/RSRP calculations are done at the exact location provided by the user.
		* Time Granularity is currently not supported by the Prediction Function (design limitations of the minimal, emulated, pre-determined traffic prediction)
		* Upper limit on the number of elements (10 each) in the routes and routeInfo structures (arrays) to not affect user experience and respoy

		## Our fith MEC application: how to create a new MEC Services

		The purpose of this MEC Service application is to provide a custom MEC service that can be use by other MEC applications. For the purpose of this tutorial, our MEC service is simulating some complex calculation based on a set of data provided by the MEC use.
		We will use a second MEC application to exploit the features of our new MEC services.

		In this clause, we use the following functionalities provided by MEC-011:
		- Register a new service
		- Retrieve the list of the MEC services exposed by the MEC platform
		- Check that our new MEC service is present in the list of the MEC platform services
		- Execute a request to the MEC service
		- Delete the newly created service

		Note: We will use a second MEC application to exploit the features of our new MEC services.

		Reference: ETSI GS MEC 011 V3.2.1 (2024-04) Clause 5.2.4 Service availability update and new service registration

		%% Cell type:markdown id: tags:

		### Bases of the creation of a MEC service

		#### Introduction

		From the user perspective, a MEC service provides a set of endpoints which describe the interface of the MEC service (see [HTTP REST APIs
		concepts](https://blog.postman.com/rest-api-examples/)). These endpoints come usually with a set of data structures used by the one or more endpoints.

		Our service is really basic: it provide one endpoint:
		- GET /statistic/v1/quantity: it computes statistical quantities of a set of data (such as average, max, min, standard deviation)

		The body of this GET method is a list of datas:
		```json
		{"time":20180124,"data1":"[1516752000,11590.6,11616.9,11590.4,11616.9,0.25202387,1516752060,11622.4,11651.7,11622.4,11644.6,1.03977764]"}
		```

		The response body is the list of statistical quantities:
		```json
		{"time":20180124,"avg": 0.0,"max": 0.0,"min": 0.0,"stddev": 0.0 }
		```

		%% Cell type:markdown id: tags:

		#### MEC mechanisms to create a new service

		As described in ETSI GS MEC 011 Clause 5.2.4 Service availability update and new service registration, to create a new MEC service, the following information is required:
		- A MEC Aplication instance: this is the MEC application providing the new MEC service (ETSI GS MEC 011 V3.2.1 Clause 8.2.6.3.4 POST)
		- A ServiceInfo instance which describe the MEC service (ETSI GS MEC 011 V3.2.1 Clause 8.1.2.2 Type: ServiceInfo)
		- As part of the ServiceInfo instance, a TransportInfo (ETSI GS MEC 011 V3.2.1 Clause 8.1.2.3 Type: TransportInfo) instance descibes the endpoints to use the MEC service

		When created and available, all the other MEC applications are notified about the existance of this MEC service.

		## Annex A: How to use an existing MEC sandbox instance

		This case is used when the MEC Sandbox API is not used. The procedure is the following:
		- Log to the MEC Sandbox using a WEB browser
		- Select a network scenario
		- Create a new application instance

		When it is done, the newly created application instance is used by your application when required. This application instance is usually passed to your application in the command line or using a configuration file
