Without this change, using metrics with core setup configurations
(configs/vonr.yaml for example) would not be possible. Having one
metrics section for whole config file causes every NF to start metrics
server on same port causing an abort.
* [HSS] Enable Change Streams
* Enable Events and Timers in HSS
* Integrate change streams in dbi
* mongodb should be configured with replica sets enabled to use feature
* Change streams are optional in HSS
* Timer will poll change stream for changes in the database
* As changes are detected, event is created to perform the correct
action
* Changes made as suggested
When UE would send a request to release PDU session, AMF would
eventually send "PDU Session Resource Release Command" downlink to both
UE (N1) and gNB (N2). Each UE and gNB would then reply with "PDU Session
Resource Release Response" indicating they released their own resources.
Usually the first one to respond would be gNB. SMF made an assumption
that this would always be the case. And it would wait for signal that UE
resources were freed, before releasing session resources. But
occasionally the situation is that UE responds first, and SMF releases
resources prematurely.
This situation does not normally occur. But under high stress (100's of
UE PDU releases at the same time) this happens occasionally.
According to the standard, this situation is perfectly normal.
3GPP TS 23.502 Rel. 16
4.3.4.2 UE or network requested PDU Session Release for Non-Roaming and
Roaming with Local Breakout

Steps 8-10 may happen before steps 6-7.

* Introduce Cancel Location and Insert Subscriber Data features to HSS.
* HSS database will keep track of last known MME and Update Time
* Purged UE flag is established in HSS for future PUR handling
* HSS Thread will connect to database and watch change stream
mongoDB must be configured with a Replica Set to use this
* HSS will send IDR if subscription data changes
* HSS will send CLR to old MME if MME host or realm changes
* Function created to allow ULA and IDR to generate Subscription-Data AVP
* MME Hostname and Realm shown in WebUI
* Resolve freeDiameter errors
During a ULR, if database does not contain a last known MME, a CLR is being sent to a Null destination. This will ensure that a destination is available in the database before sending the CLR.
* Removed change streams. Added PUR handling.
* newline needed at end of file.
* Removed temp variable.
* * Change WebUI to 2x2 display
* Including UE Purged indicator
* Using pointers in ogs_subscription_data_t
* better memory mangement with pointers
* Tweak to Destination used by hss_s6a_send_idr to use last known MME
* Check for null mme_host and mme_realms
Do this before trying to compare the strings.
In case that APN name sent from UE does not case-match with the one
configured in the database, AMF would reject the registration with the
message:
[gmm] WARNING: [imsi-xxx] DNN Not Supported OR Not Subscribed in the
Slice (../src/amf/gmm-handler.c:1051)
Add additional check when receiving Deregistration Notification from
UDM. UE should already be in registered state before accepting the
request and deregistering the UE.
Also add additional check that PCF association policy exists before
sending a delete request to PCF.
* npcf-smpolicycontrol - enabled or disabled
* npcf-policyauthorization - enabled or disabled
Only one of npcf-smpolicycontrol and npcf-policyauthorization cannot be enabled. (../src/pcf/sbi-path.c:151)
They can be enabled or disabled together.
OpenAPI specification for sending NF discovery query with
"service-names" parameter is defined as folowing:
- name: service-names
...
style: form
explode: false
According to OpenAPI specification, this means array items
should be delimited with a comma character (example: /users?id=3,4,5).
