Hola,
Mi nombre es Javier, primero debo pedir disculpas por mi poco=20
conocimiento sobre la herramienta. Estoy intentando conectar un core=20
funcional de red LTE (EPC) con Kamailio y he utilizado la soluci=C3=B3n de=20
Polaris Networks que viene en una imagen con ambas funcionalidades.
El EPC est=C3=A1 correctamente configurado y funcionando ya que puedo tener=20
conexi=C3=B3n de datos en mi UE, tambi=C3=A9n he activado todas las opciones =
de=20
IMS en el EPC: He creado el APN con identificador ims, el QCI de la=20
portadora por defecto que asigna es 5 (para se=C3=B1alizaci=C3=B3n SIP), el M=
ME=20
tiene activado la opci=C3=B3n de soportar Voz IMS sobre la sesi=C3=B3n PS y l=
os=20
nodos HSS y PCRF est=C3=A1n configurados con las interfaces en las=20
direcciones y puertos Cx-HSS 127.0.0.1:3868 y Cx-PCRF 10.11.0.35.
Hay varios par=C3=A1metros que no s=C3=A9 si es necesario activar como por=20
ejemplo, en el PCRF la personalizaci=C3=B3n del QCI para el tipo de media, si=
=20
debo incluir el OCS y OFCS como nodos, o si en el perfil de mi APN debo=20
incluir autenticaci=C3=B3n por PDN AAA.
La configuraci=C3=B3n que utilizo para el IMS es la siguiente:
imsrealm =3D net1.test
imsport =3D 5060
pcscfgmip =3D 10.77.0.35
pcscfgmipintf =3D eth6
pcscfrxip =3D 10.102.81.111
pcscfrxipintf =3D eth1

icscfmwipintf =3D lo:21
icscfcxip =3D 127.0.0.20
icscfcxipintf =3D lo:20
scscfmwip =3D 127.0.0.23
scscfmwipintf =3D lo:23
scscfcxip =3D 127.0.0.22
scscfcxipintf =3D lo:22
audiobandwidth =3D 64
videobandwidth =3D 128
epcrealm =3D epc.mnc001.mcc001.3gppnetwork.org
pcrfhost =3D pcrf2.morsecore
pcrfrxip =3D 10.11.0.35
pcrfrxport =3D 3868
hsshost =3D hss6.morsecore
hsscxdxip =3D 127.0.0.1
hsscxdxport =3D 3868

Ambos n=C3=BAcleos est=C3=A1n corriendo en la misma m=C3=A1quina pero tengo=20
deshabilitada la opci=C3=B3n de PCRF Co-located with IMS para poder editar el=
=20
pcrf host name ya que si lo habilito no alcanza la peer pcrf.localhost=20
aunque en el DNS est=C3=A9 bien configurado. Mi UE no es capaz de lanzar el=20
REGISTER por =C3=A9l mismo, cuando va a realizar una llamada y estoy=20
utilizando la aplicaci=C3=B3n de Google IMSDroid para poder lanzar las=20
peticiones SIP y comprobar el funcionamiento del IMS. En la aplicaci=C3=B3n=20
del UE la configuraci=C3=B3n es la siguiente:
Identidad: Alice
Public Identity: sip:<MSISDN>@net1.test (MSISDN=3D8800000451 configurado=20
previamente en el EPC)
Private Identity: sip:<IMSI>@net1.test (IMSI incluyendo MCC y MNC)
Password: alice
Realm: net1.test (Aunque no s=C3=A9 si debo poner aqu=C3=AD=20
epc.mnc001.mcc001.3gppnetwork.org, pero entonces la petici=C3=B3n da error)
Network: Proxy-CSCF Host: 10.77.0.35:5060 Transport UDP and NO=20
Proxy-CSCF discovery.

Entonces, lanzo mi petici=C3=B3n y el log del nodo P-CSCF es es siguiente:
