It turns out that many LTE carriers reuse the same keystream when two calls are made within a single radio connection. An attacker can then record an encrypted conversation, then immediately call the victim after that conversation. The attacker can now access the encrypted keystream, and as the keystream is identical to the first conversation, the first conversation can now be decoded.
