When can free5GC be upgraded to support the newer version of 3GPP REL-15 or even REL-16

Dear free5GC support Team,
Today, we tried to test the Nudm interface functions with the downloaded package from github. Unfortunately, we found that the free5GC SW on github seemed to only support the earlier version of 3GPP REL-15.

For example, when we query the 5G subscriber AMF data through “nudm-sdm” service API:
(1) The query with “apiVersion = v1” could be working and fetch the sub. data. e.g.,
“curl -X GET http://xx.xx.xx.xx:/nudm-sdm/v1/imsi-240814000000001/am-data?plmn-id=%7b%22mcc%22%3a+%22111%22%2c+%22mnc%22%3a+%22222%22%7d|jq .”
(2) The query with “apiVersion = v2” was always failed with the similar curl command. e.g.,
“curl -X GET http://xx.xx.xx.xx:/nudm-sdm/v2/imsi-240814000000001/am-data?plmn-id=%7b%22mcc%22%3a+%22111%22%2c+%22mnc%22%3a+%22222%22%7d|jq .”

After reviewed the relevant coding published on github, it showed that only “apiVersion=v1” can be supported, which was only written in the much eariler version of 3GPP REL-15. While, at present, almost all the 5GC NFs are designed by following the newer versions of 3GPP REL-15 or even REL-16. Namely, “apiVersion=v2” of Nudm_SDM Service API should be mandotarily supported.

So, we have the questions need your support that:
(1) Is what we identified issue in current free5GC SW the truth?
(2) What’s the life cycle management plan of free5GC SW, and when can free5GC be upgraded to support the newer version of 3GPP REL-15 or even REL-16?

Many thanks//Andy

Hi @encxuzh163,
(1) According to the free5GC GitHub repository, some APIs in the current release of free5GC are written based on older versions of 3GPP REL-15 (V15.3.0). If you are interested in contributing to or modifying the open-source code, you are welcome to do so at any time.
(2) There is no information about the life cycle management plan of free5GC. However, according to the free5GC GitHub repository, free5GC is continuously maintained the source code.It is possible that the code will not be released until a stable version is available, and new features mentioned in R16 and even R17 are being added.

Brs,
