2.5 SoR Traffic Rejection Logic

Traffic steering is achieved by accepting or rejecting a ULR message.

The SoR application uses on/off rejection, all ULR messages from some MNO are rejected until the average share of this MNO goes below its configured value. This can result in bursty behavior, as all ULR messages would be rejected for some time leading to bursts of re-registrations.
