Techniques include, in response to a first communication network of a hybrid communication system being aware of a potential for a mismatch of reported authentication parameters associated with a second communication network of the hybrid communication system, wherein the first communication network is used to transport the reported authentication parameters to the second communication network, the first communication network preventing the mismatch of the reported authentication parameters. In one example, the first communication network is an LTE network and the second communication network is a CDMA2000 network.
