Why not use SGW-C, SGW-U?

acetcom commented 2 years ago

@Mozartor2

Could you send me a gdb log as below?

$ gdb ./install/bin/open5gs-smfd
gdb> run
..(Crashed)
gdb> bt full

Thanks a lot! Sukchan

@Mozartor2

No debug symbols. Can you build the source code and run the gdb program?

$ git clone https://github.com/open5gs/open5gs
$ cd open5gs
$ meson build --prefix=`pwd`/install
$ ninja
$ cd ..
$ gdb ./install/bin/open5gs-smfd

For more information, you can see the following link. https://open5gs.org/open5gs/docs/guide/02-building-open5gs-from-sources/

Thanks a lot! Sukchan

After compiling with source code (git 2.4.0), I replaced open5gs-smfd installed with ppa(version 2.4.0 ) then:

gdb ./install/bin/open5gs-smfd
run -c /etc/open5gs/smf.yaml

VoLTE Call Successful......

描述：5G Core and EPC (metapackage)
 Open5GS is a C-language implementation of 5G Core and EPC Packet Core, i.e. the core network of an NR/LTE network (Release-16)

 This is a metapackage that depends on all the open5gs parts.

These two version（github 2.4.0 and ppa 2.4.0 ）of the code should be different

Mozartor2 commented 2 years ago

We test Open5GS 2.4.1 install with Package Manager，The SMF also Crashes。

@Mozartor2

You can use nightly build package provided by osmocom from the below link. https://build.opensuse.org/package/show/network:osmocom:nightly/open5gs

You can find the installation guide in the quickstart link. https://open5gs.org/open5gs/docs/guide/01-quickstart/

Please let me know if you have still this problem.

Thanks a lot! Sukchan

nightly build ：open5gs_2.4.1.202201130026 VoLTE reg succeeded，SAA message returned by Hss missing CX-User-Data AVP，when initializing a volte call，LIA failed ,the msg does not contain ServerName（scscf:port）. Both version of the program(github build and nightly build 2.4.1) use the same configuration file and kamaikio。

@Mozartor2

The SMF crash issue seems to be gone. Right?

Please share pcap or log/conf files if you have any further problems.

Thanks a lot! Sukchan
