Make the clamping of HRPD mobile phone go into the method for eHRPD network
With reference to shown in Figure 1, this figure is the schematic flow sheet that the method embodiment of eHRPD network is gone in the HRPD of making mobile phone provided by the invention clamping, introduces the step of this method embodiment below in detail.
Step 101, the portable terminal that is mounted with HRPD mobile phone card sends to eHRPD server network control node by wireless access network and inserts request message.
HRPD mobile phone card can be subscriber identification module (User Identity Module, UIM) card.
Step 102, core network control node is initiated the request of eHRPD network authentication to portable terminal.
After step 103, portable terminal were received the request of eHRPD network authentication, HRPD mobile phone Cali calculated to obtain the first authentication calculations value with first authentication parameter of HRPD mobile phone card according to the HRPD authentication arithmetic.The HRPD authentication arithmetic is the current authentication arithmetic of supporting of HRPD card, the MD5 authentication arithmetic of for example CAVE authentication arithmetic of 1X, or HRPD.First authentication parameter can be the user profile of HRPD mobile phone card.
Step 104, portable terminal,, are calculated to obtain the second authentication calculations value according to eHRPD network authentication algorithm as input with the first authentication calculations value.
EHRPD network authentication algorithm is standard EAP-AKA ' algorithm.Carry out the transformation of authentication calculations value with the first authentication calculations value as input in the step 104, make the second authentication calculations value that calculates be the result according to eHRPD network authentication algorithm.
Step 105, portable terminal sends to core network control node with the second authentication calculations value.
Step 106, core network control node sends to core net AUC to the second authentication calculations value, and initiates authentication request.
Core net AUC can be authentication and authorization charging server (Authentication, Authorization and Accounting Server, AAA server).
Step 107, core net AUC extracts first authentication parameter of HRPD mobile phone card to the authorization data storehouse.
The user profile of the HRPD mobile phone card in first authentication parameter of HRPD mobile phone card and the step 103 is identical, and user profile that can HRPD mobile phone card leaves the authorization data storehouse in advance in.The authorization data storehouse specifically can be home subscriber server (Home Subscriber Server, HSS),
Step 108, first authentication parameter that core net AUC utilizes the HRPD mobile phone card that extracts from the authorization data storehouse calculates the 3rd authentication calculations value according to described HRPD authentication arithmetic, with the 3rd authentication calculations value as input, according to eHRPD network authentication algorithm, calculate the 4th authentication calculations value.
Step 109, relatively whether the second authentication calculations value is identical with the 4th authentication calculations value in core net AUC, if comparative result is identical, then returns authentication to core network control node and passes through message.
Step 110 is receiving authentication by after the message, and core network control node allows the clamping of HRPD mobile phone to go into the eHRPD network.
By transforming simultaneously at mobile terminal side and network side, make the user to use first authentication parameter and HRPD authentication arithmetic in the current HRPD mobile phone card to calculate earlier at mobile terminal side, again with this result calculated as input, according to eHRPD network authentication algorithm, calculate to obtain the second authentication calculations value.Equally, also carry out same computational process at network side, be used for authentication thereby can make mobile terminal side and network side obtain same authentication calculations value (the second authentication calculations value and the 4th authentication calculations value).When authentication is passed through, under the situation of not changing card, make the clamping of HRPD mobile phone go into the eHRPD network.
