REST API
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 |
---|---|---|---|
| /v#/nodeb/x2-setup | POST | |
| /v#/nodeb/endc-setup | POST | |
/v#/nodeb/<ranName>/reset * | PUT | ||
1 | Health Check Request | /v#/health | GET |
2 | Get nodeb data Request | /v#/nodeb/<ranName> | GET |
3 | Update GNB Request | /v#/nodeb/gnb/<ranName> | PUT |
4 | Insert ENB Request | /v#/nodeb/enb | POST |
5 | Update ENB Request | /v#/nodeb/enb/<ranName> | PUT |
6 | Delete ENB Request | /v#/nodeb/enb/<ranName> | DELETE |
7 | Shut Down Request | /v#/nodeb/shutdown | PUT |
8 | Get All nodeb States Request | /v#/nodeb/states | GET |
9 | Get All E2T Request | /v#/e2t/list | GET |
10 | E2M set parameters | /v#/nodeb/parameters | PUT |
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. |
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 | |
406 | Node Already Exist | Insert eNB to existing RAN | |
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 | |
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. |
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 | HTTP Error 503 Service Unavailable | |
---|---|---|---|---|---|
Get nodeb data | 404 | 500, 501 | |||
Update GNB, Insert ENB, Update ENB Delete ENB | 401, 402, 406 | 404 | 500, 501 | ||
Shut Down | 405 | 500, 501, 502 | 511 | ||
Get All nodeb | 500, 501 | ||||
Get All E2T | 500, 501 | ||||
E2M Set Parameters | 401 |
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)

SDL Notification
When a RAN (eNB or gNB) is added, updated or deleted in RNIB, or when a state of RAN is changed, the following SDL Notification generated.
E2M supports 2 types of SDL Notification, the client can subscribe to each of them:
- RAN Manipulation - The Notification specifies the RAN Name + the action (Added, Updated, Deleted)
- RAN Connection Status Changed - The Notification specifies the RAN Name + its Status
In the following scenarios E2M generates SDL Notification:
Issue | RAN Connection Status Changed | RAN Manipulation | Comments |
---|---|---|---|
Setup Request from RAN | + (Connected) | Only in case the NodeB was previously Disconnected or it is a new RAN Note that the Function might be changed. In case new RAN - In most of the cases the status changed to Connected, n the rare case where the Routing Manager is down - E2M generate SDL RAN Connection Status Changed to Disconnected. | |
+ (Updated) | In case the NodeB was already Connected and there was some changes | ||
Insert eNB API | + (Added) | ||
Update eNB API, Update gNB API | + (Updated) | ||
RIC Service Update | + (Updated) | Only in case there was some changed (Function Added / Modified / Deleted) | |
Lost Connection, Red Button (Shut Down) | + (Disconnected) | Only in case the NodeB was previously Connected | |
E2T Restart, Keep Alive decides this E2T Instance is dead | + (Disconnected) | Only in case this NodeB was under the control of this E2T Instance and it was previously Connected | |
Delete eNB API | + (Deleted) |
Here are the values:
Channel | Events |
RAN_CONNECTION_STATUS_CHANGE | <RAN_NAME>_CONNECTED |
RAN_MANIPULATION | <RAN_NAME>_ADDED |
