2. challenge authentication: PDSN challenges and an ID value to terminal, and the user goes out response according to corresponding challenge, ID value and the local cryptographic calculations of depositing, and response is sent back to PDSN.Then, PDSN sends authentication request (comprising challenge, response and ID value) to RADIUS, RADIUS is according to challenge and ID value and the cryptographic calculations response corresponding to this user self deposited, if the response that response and terminal are calculated is identical, then passes through mandate accordingly.Otherwise send the authentication refuse information to PDSN, the PDSN termination is connected with terminal.
3. when terminal was not taken NAI information to PDSN, PDSN can construct NAI according to MSID and carry out corresponding authentication.
Therefore, the authentication functions that AAA cooperates with PDSN is very perfect, also can carry out reliable authentication in the presence that does not have HLR.
The present invention is described as follows for the management of chargeing: in the cdma-1x network, the charging content of packet domain is divided into two parts: air traffic channel is chargeed partly and network side charging part.Air traffic channel is chargeed and is partly sent to PDSN by the PCF collecting charging information, and the network side charge information is collected by PDSN, and PDSN compiles the charge information and the network side charge information of air traffic channel, sends to aaa server by radius protocol then and charges.
