Abstract
The present invention provides VoIP authentication in 4G VoLTE, and also provides an extra authentication method of VoLTE for achieving communication security. The key point of the extra authentication method of VoLTE is: when a 4G mobile phone is turned on for the first time, a security registration sequence number will be random generated by the 4G mobile phone, and sent with IMSI and IMEI through TLS to an account assignment server for comparison and storage. Thereafter the account assignment server sends an account and a password in a database corresponding to IMSI to the 4G mobile phone, and then the 4G mobile phone conducts VoIP authentication with a SIP server for standby or communication.
