API Request Overview

In the URI of each method in this document we write “V#” instead of V1, since when moving from Version to Version sometimes we forgot to update it in the document. So to make our life easier, V# covers the Latest version.

Standard API Request Headers

Approved Standard Headers are documented at https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

#	Header	Required?	Description
1	Accept	YES	Specifies the format of the response message body. Structured text message payloads are required to support application/json. No other format is permitted. As they are the only supported format, the accept header is not relevant for those requests.
2	Content-type	YES	Determines the format of the request content. Only application/json is supported.

RESTful Web Services Interface Specification

#	API	Resource After base URI	HTTP Verb
	~~X2 Setup Request Message Request~~ (deprecated)	/v#/nodeb/x2-setup	POST
	~~ENDC Setup Request Message Request~~ (deprecated)	/v#/nodeb/endc-setup	POST
	~~Reset nodeb Request~~ (deprecated)	/v#/nodeb/<ranName>/reset *	PUT
1	Health Check Request	/v#/health	GET
2	Get nodeb data Request (Changed)	/v#/nodeb/<ranName>	GET
3	Update GNB Request (New)	/v#/nodeb/<ranName>/update	PUT
4	Shut Down Request	/v#/nodeb/shutdown	PUT
5	Get All nodeb	/v#/nodeb/ids	GET
6	Get All E2T Request	/v#/e2t/list	GET

Note: Due to router problem we change the Endpoint of Reset nodeb to /v1/nodeb-reset/<ranName>.

Error Handling

Note that, in some scenarios, Client may receive error responses that originate from the network layers. The content of these responses will not conform to the exception schema specified here.

#	Header	Required?	Description
1	errorCode	YES	Code which identifies the error
2	errorMessage	YES	Human readable text

Error Example:

{

         "errorCode": 402,

         "errorMessage": “Mandatory fields are missing”

}

Here is the list of HTTP status code:

HTTP Error	errorCode	errorMessage	Details
202 Accepted	510	No E2T Instance available.	The existing RAN can't associated with any available E2T Instance. When E2T will be identified, this RAN will be served.
202 Accepted	511	No Routing Manager Available	Currently there is connectivity to the Routing Manager. E2M will try later.
400 Bad Request	401	corrupted json	Can't parse the payload of the body
	402	validation error	E.G: Mandatory fields are missing or invalid (The value isn't according expected);
	403	Activity <activity name> rejected. RAN current state <state> does not allow its execution	E.G: Reset request is sent when state isn't Connected
	405	command already in progress	E.G: 2 parallel Red Button were sent
404 Not Found			If the resource name doesn't exist (e.g.: nodec instead of nodeb) - the system returns HTTP Error 404 with "404 page not found" text.
	404	resource not found	The classic 404 - Resource ID doesn't exist in the system
	406	No RAN in Connected State	e.g.: RAN Health Check and no one in Connected
415 Unsupported Media Type	415	Header validation error	In case there is a body and header application/json is missing - error.
500 Internal Server Error	500	RNIB error
	501	Internal Server Error. Please try again later
	502	RMR error
503 Service Unavailable	510	No E2T Instance available.	The New RAN can't be added, please try later.
503 Service Unavailable	511	No Routing Manager Available	The New RAN can't be added, please try later.

Here is the list of HTTP status code and list of the error codes for our APIs:

	HTTP 202 Accepted	HTTP Error 400 Bad Request	HTTP Error 404 Not Found	HTTP Error 500 Internal Server Error
Get nodeb data			404	500, 501
Update GNB		401, 402	404	500, 501
Shut Down	511	405		500, 501, 502
Get All nodeb				500, 501
Get All E2T				500, 501

In addition, there are 2 Basic HTTP error happens before the handlers are calling:

HTTP Error 404 Not Found (Body is empty) - The Resource name isn't found (e.g.: Call /v#/nodec instead of /v#/nodeb)
HTTP Error 405 Method Not Allowed (Body is empty) - Wrong HTTP VERB to known resource name *e.g.: Call HTTP GET v#/nodeb/x2-setup)
