OpenAPI dictates that certain arrays should have at least one item,
otherwise they should not be present.
This includes lists for IPv4/v6 addresses, TAI/TAC lists, ...
Add a check if there is at least 1 item, before creating an array.
Also move variable declarations to inner blocks, to prevent some
accidental usage out of wanted scope.
Support for change stream is only available in mongoc >=1.9.0
- Disabled related functions in dbi.
Support for bson to json used in debug statement only in libbson >=1.7.0
- Simple debug message in lower versions
AMF subscribes to UDM for each registered UE.
At the moment, UDM does not send callback to AMF when any of the UE's
properties in the database changes.
At the moment, AMF does properly parse the ModificationNotification, but
does not do anything useful.
* Cancel Location while Idle Fix
* Forgot about SGSAP on MME Change.
Added "action" to sgsap_send_detach..
* Make handle_clr uniform with other handlers
* Added Robustness for Any Detach Type
* Memory wasn't freed upon CLR for unknown IMSIs
* Moving MME Detach to new PR
TS29.500
Ch 6.11 Detection and handling of late arriving requests
In Open5GS, this part was hard-corded.
HTTP2 Client sends a request and waits for 10 seconds.
If no response is received from the HTTP2 Server,
HTTP2 Client performs the exception handling.
In this commit, HTTP2 client sends Header with setting Max-Rsp-Time to 10 seconds.
However, HTTP2 server has not yet been implemented to process this value.
The server is still processing using hard-corded values (10 seconds).
* [MME] Support for Insert Subscriber Data
* Supported AVPs in IDR will overwrite existing subscription information
* Provide error on partial APN updates
* IDR and ULA use same function to process AVPs
* Move subdatamask values into s6a, so both HSS and MME can use them
* Updates are not actioned at this time. A Re-attach is required for
most changes to take effect
* Memory issue on IDR exceptions
* Remove of handling MSIDSN change until DSR is used
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
* 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.
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).
== Known limitation ==
Placing npcf-smpolicycontrol and pcf-policyauthorization
in different NFs is not supported. Both npcf-smpolicycontrol
and pcf-policyauthorization should be placed in the same NF.
The 3GPP-Charging-Characteristics is an operator specific AVP
(optional). The 3GPP-Charging-Characteristics can be filled by the HSS
and pass through to the Gx interface.
See ETSI 29.212 5.4.0.1 for further details.
* Add Diameter Dictionary Elements
* Initial IDR Framework
* Resolve Compile Issues
* Moving Closer
* Compile error
* Somewhat Working stuffing Code
* Add Timestamp Changes
* Cleanup some of this code. mme_s6a_handle_idr in s6a-handler.c removed for now, since it will only come in handy when IDR flag is set to request current location, which would involve breaking out into paging. I think there's a few other things we can do just within fd-path first.
* further removal of mme_s6a_handle_idr
* CLR while idle is broken after 7031856cd7
Cancel Location Request arriving while UE is idle will not proceed to paging due to this check for S1 connection. Using new flag "isAnswer" to bypass this check to allow paging to occur when we are not doing a AIA/ULA related procedure.
* No Context Setup is required when sending the detach request. If the paging was due to wanting to send a Detach Request to the UE, then we fast track to sending the detach request.
* emm-sm.c:
In the case of MME initiated detach while UE is idle, there is no initial conext setup. We go right from the service request after paging into sending the detach request. TS23.401
mme-path.c:
Using nas_eps.type in the case of MME Initiated Detach while UE is idle does not work. nas_eps.type would represent the service request.
mme-s11-handler.c:
After S11 action, no action should be taken. We want to wait for the detach accept from the UE before proceeding with the S1 release (detach).
* InitialContextSetup should occur for detach.
