* [SBI] Fix converting PatchItem to JSON
* [UDR] Add support for endpoint for patching subscription data
Add support for PATCH HTTP method for the following endpoint:
/subscription-data/{ueId}/context-data/amf-3gpp-access
Currently does not change any data in the database.
* [UDM] Add support for endpoint for patching subscription data
Add support for the following endpoint, HTTP PATCH method:
/nudm-uecm/v1/{ueId}/registrations/amf-3gpp-access
The endpoint is used when UE deregisters from the core, and AMF
sends a subscription modification request with "purgeFlag" set.
* [UDM] Add check for same GUAMI when patching subscription data
* [AMF] Send deregistration event to UDM
When UE sends deregistration request, AMF needs to send a
Nudm_UECM_Deregistration request to UDM.
The order of requests is now the following:
- send PDU session release to SMF
- send deregistration event to UDM
- send AM policy control release to PCF
According to the following standards the response to the endpoint
/nudm-sdm/${supi}/sm-data should be an array of
SessionManagementSubscriptionData objects, instead of only one object.
TS 29.503 version 16.6.0
TS 29.505 version 16.4.0
UDR now responds to the request with only item in the array.
UDM copies all items as is.
SMF uses only the first item in the array, even if there are more
present.
