Remove these F1-C port numbers. The configuration is not actually
applied, and the default F1-C port number 38472 (see F1AP_PORT_NUMBER)
is hardcoded in the F1 module.
For the moment, I leave the configuration option, in case we want to
allow to configure the port numbers later).
The 5G-RFsim F1 test tested multiple DUs at one CU. This
functionality is retained in the new F1+E1 test.
The 5G-RFsim E1 test tested a single CU-UP at a single CU-CP. Here, we
extend to use multiple CU-UPs, one for each DU. The associated is
ensured by using three different F1-U transport networks, one for each
DU/CU-UP pair.
3GPP has the concept of a gNB-CU-UP ID and a (separate) gNB ID (for gNB,
CU-CP). This commit introduces the gNB-CU-UP as a separate ID that has to be
set in the configuration file when running as a CU-UP. For the
CU/monolithic gNB, it is optional (but needs to be the same as the
gNB-ID if specified).
The CU-UP ID is necessary, as some entities, e.g., the e2 agent, need to
signal both IDs, e.g., to reconcile a CU-CP and (multiple) CU-UP(s)
belonging together.
