2.2) the Softswitch response needs the encryption method of authentication, require access device is carried out authentication;
2.3) access device increases the equipment mark code after the encryption method that provides through Softswitch is encrypted in registration message, once more to the Softswitch request registration;
2.4) equipment mark code after Softswitch is relatively encrypted and the encrypted result of oneself calculating, whether consistent determining whether agreed to register according to comparative result.
The detailed step of said step 3) comprises:
3.1) access device increases equipment mark code in call request message, to Softswitch request authentication;
3.2) the Softswitch response needs the encryption method of authentication, require access device is carried out authentication;
3.3) access device increases the equipment mark code after the encryption method that provides through Softswitch is encrypted in call request message, once more to Softswitch request authentication;
