RNI service initialisation error

[hcr-git]

Hello,

we are configuring the RNIService in the emulation example: emulations/mec/extUeAppMecApp. For now, we are substituting the Location service configuration by the RNI service configuration in omnetpp.ini file (the objective is to change UeApp.py and MecApp.py in order to use RNI):

[in omnetpp.ini file]

---- RNI service

.mecHost1.mecPlatform.mecService[0].typename = "RNIService" .mecHost1.mecPlatform.mecService[0].localAddress = "mecHost1.virtualisationInfrastructure" .mecHost1.mecPlatform.mecService[0].localPort = 10020 .mecHost.mecPlatform.mecService[0].rng-0 = 1 # request service time .mecHost.mecPlatform.mecService[0].rng-1 = 2 # subscription service time .mecHost.mecPlatform.mecService[0].requestServiceTime = 20us .mecHost*.mecPlatform.mecService[0].subscriptionServiceTime = 11us

---- RNI service

When executing the emulation in the command line, we got the following error:

[execution results] ...... Setting up Cmdenv...

We are using Simu5G 1.2.1.

Can you help us?

Thank you, Helena Rodrigues

Hello,

please try to add the parameter **.hasRNISupport = true to your INI file and see if that solves the problem.

Best regards. Giovanni
