What is RRC setup success rate?

This means that if the network has a higher ratio of RRC Mo-Signalling requests then it will have a lower RRC Success Rate. Usually, Mo-Signalling is around 20 to 25% while Mo-data has the highest percentage. Still it can vary from network to network based on TAC planning and mobility strategy.
