- Set the correct QoS flow ID to associate a correct QoS flow to the
bearer: the UE would misassociate otherwise
- Set the DRB as the default: the handler applies bool with true==1, so
use bool value
This allows to communicate with multiple remote hosts. A further
improvement would be to refactor this piece of code into a function and
call it only when necessary, i.e., when we know the remote host, or want
to add one to a list of hosts.
This commit introduces the capability to handle multiple CU-UPs. It uses
a RB tree and puts the CU-UPs into the tree. Upon the connection, it
associates UEs to CU-UPs in a round-robin fashion.
A later commit will introduce an RB tree to manage multiple CU-UPs. The
RB tree implementation relies on some macros that generate RB tree
functions. Functions using the RB tree implementation will be grouped in
this file.
The E1AP Setup Request contained the network configuration (IP address,
ports) as well as the actual E1AP Setup Request application data
(Supported PLMNs, ...). This has the drawbacks that
- The E1AP Setup Request is stored to retrieve IP addresses in the E1AP
module, which is confusing as the Setup Request, per standard, has no IP
info
- The CU-CP received an E1 Setup Request for configuration during start
up, but it did not actually receive such Setup Request, but merely the
IP configuration to set up the socket
This commit splits the E1AP Setup Request into a "real" Setup Request
for application data, and creates a new type e1ap_net_config_t to group
all IP configuration data. Further, a new ITTI message type
E1AP_REGISTER_REQ is introduced to group both types. What happens is
- RCconfig_NR_CU_E1() reads both E1AP application-level data and IP
configuration, as previously
- The data is sent to the CU-CP. It discards the E1AP Setup Request
data, and only uses the network configuration to set up the socket
- The data is sent to the CU-UP. It uses the network configuration to
connect to the CU-CP, and then sends the E1AP Setup Request to the
CU-CP.
Currently, the CU-CP still stores the Setup Request locally, which will
be changed in the next commit to send it to the RRC.
The DRBLists inside E1AP message are for E-UTRAN. We don't support that
with our CU-CP/UP yet, so remove it to reduce ambiguity and complexity.
For the same reason, we remove the CN Support, which for us is always
"NR".

This enables build_oai to detect if the output terminal supports colors.
If it does, it will use colors in its output. If it does not, it will
just print the text, without color codes, improving legibility.

The RRC container is to be handled by the msg handler in
mac_rrc_dl_handler.c. Therefore, don't forward the RRC message, but copy
it into the message so the handler can take the action.

The UE should measure on the SSB, otherwise it does not see anything.
Hence, this commit fixes the meas-config to request the UE to measure
on the right frequency.
