Hello,
My name is Javier, I must first apologize for my little knowledge about
the tool and my poor English. I am trying to connect a functional core
network LTE with Kamailio and I have used the Polaris Networks Solution
that brings an iso with both functionalities.
The EPC is correctly configured and working because I can have data
connection in my UE, I have also activated all the IMS options in the
EPC: I have created the APN with ims identifier, the default carrier QCI
assigned is 5 (for SIP signaling), the MME has activated the option to
support IMS Voice over the PS session and the HSS and PCRF nodes are
configured with the interfaces at the addresses and ports Cx-HSS
127.0.0.1:3868 and Cx-PCRF 10.11.0.35:3868 .
There are several parameters that I do not know if it is necessary to
activate, for example, in the PCRF the customization of the QCI for the
media type, if I must include the OCS and OFCS as nodes, or if in the
profile of my APN I must include authentication by PDN AAA.
The configuration I use for the IMS is as follows:
imsrealm = net1.test
imsport = 5060
pcscfgmip = 10.77.0.35
pcscfgmipintf = eth6
pcscfrxip = 10.102.81.111
pcscfrxipintf = eth1
icscfmwip = 127.0.0.21
icscfmwipintf = lo:21
icscfcxip = 127.0.0.20
icscfcxipintf = lo:20
scscfmwip = 127.0.0.23
scscfmwipintf = lo:23
scscfcxip = 127.0.0.22
scscfcxipintf = lo:22
audiobandwidth = 64
videobandwidth = 128
epcrealm = epc.mnc001.mcc001.3gppnetwork.org
pcrfhost = pcrf2.morsecore
pcrfrxip = 10.11.0.35
pcrfrxport = 3868
hsshost = hss6.morsecore
hsscxdxip = 127.0.0.1
hsscxdxport = 3868
Both cores are running on the same machine but I have disabled the
option of PCRF Co-located with IMS to be able to edit the pcrf host name
since if I enable it it does not reach the peer pcrf.localhost even if
the DNS is well configured. My UE is not able to launch the REGISTER by
itself when it is going to make a call, so I am using the Google
IMSDroid application to be able to launch the SIP requests and check the
operation of the IMS. In the application of the UE the configuration is
as follows:
Identity: Alice
Public Identity: sip:<MSISDN>@net1.test (MSISDN=8800000451 configurado
previamente en el EPC)
Private Identity: sip:<IMSI>@net1.test (IMSI incluyendo MCC y MNC)
Password: alice
Realm: net1.test (Aunque no sé si debo poner aquí
epc.mnc001.mcc001.3gppnetwork.org, pero entonces la petición da error)
Network: Proxy-CSCF Host: 10.77.0.35:5060 Transport UDP and NO
Proxy-CSCF discovery.
So, I launch my request and the log of the P-CSCF node is as follows:

I understand that everything is correct until now, but in the I-CSCF
node it appears:

Where I believe that the REGISTER message is not even forwarded, however
it seems that it gives an error that the user is unknown or not
registered but if I access the MySQL database, the registered users are:

However, I do not know if it is accessing the mounted MySQL database or
accessing the HSS and on this node, in the databases it does not contain
the user (although it must be because it is registered in the network
correctly).
In case it works, this is the trace of wireshark filtered by the
protocols S1AP, SIP and Diameter just when a REGISTER request is
launched:

I don't know if any information or configuration details are missing but
I can attach it at any time without any problem.
Regards and thank you very much in advance,
Javier Espinosa.
