More Information
Summary:A mobile communication system, and information transmitting method and device wherein are provided in the invention. By means of extending the parameter in interaction criterion protocol, the transmitting signalling on A1p link between base station controller ( or goal base station controller) and mobile switch center (MSC) emulation entity can take 2833 encrpytion control information. The MSC emulation entity transmits the cryptographic key to media gateway(or goal media gateway), and the media gateway recover the cryptographic key. Then the base station controller ( or goal base station controller) and the media gateway(or goal media gateway) can encrypt/decode the 2833 information which is to be transmitted or has been transmitted by use of the same cryptographic key. By transmitting encrypted 2833 information between base station controller and media gateway, the security of transmitting 2833 information in A2p port can de improved, and accordingly service satisfaction level of operator will be increased.
