In these cases, the serving system sends the MS global-challenge information in an AUTHREQ message to the AC The serving system6 then handles the response from the AC, that is, the authreq message This message can trigger the following additional processes in the serving system, depending on the message s contents:

Additionally, the message may contain the ANSI-41 DenyAccess parameter, which directs the serving system to release the system resources it has allocated for the MS access in question; this may include the release of the call in progress, if one exists If the MS is successfully authenticated and no additional authentication operations are requested, the serving system terminates the global challenge process and continues with normal system access processing, which may involve call origination, location update, or other serving system processes (see Figure 1111) Global Challenge when SSD is Shared If the serving system is sharing SSD, it assumes responsibility for evaluating the global-challenge information it receives from the MS Evaluation involves five tests: 1 Check that the MSID and ESN reported by the MS are valid7 2 Check that the type of air interface used by the MS to access the system is valid (eg, is the same as the type stored in the serving system s database, if so provisioned) 3 Check that the AUTHR and COUNT information was provided by the MS 4 Execute the CAVE algorithm, and verify that the AUTHR generated equals the AUTHR received from the MS

5 Finally, check that the received COUNT value matches the expected value stored in the serving system s database record for the MS If any of these checks fails, the serving system global-challenge process initiates the authentication reporting process, passing an indication of the cause of the failure Otherwise, the serving system considers the MS to have passed the global challenge The serving system processing beyond this point depends on the particular authentication policies in effect If the global challenge is considered sufficient for authenticating the MS in this case, the serving system may simply terminate the global-challenge process and continue with system-access processing (see Figure 1112) Alternatively, the serving system may pass control to either the unique challenge process or the COUNT update process to perform further authentication functions
Border System Global-challenge Process
The border system global-challenge process deals with two distinct tasks:

Serving system
OMT [AUTH=1, RAND] system access [AUTHR, RANDC, COUNT] continue with normal system access processing (eg, call origination)
Handling of RAND requests from the serving system Handling of MS access attempts under intersystem paging conditions
The first task is initiated when the border system receives a RANDREQ message from the serving system, including the RANDC that the serving system received from the MS and the serving-cell identification (the latter is information coordinated between the two systems during provisioning) The border system checks its records of current and recently used RAND values in the area corresponding to the serving cell and responds with a matching RAND, if one exists, in the randreq message One form of the second task is initiated when (a) the border system receives an IntersystemPage Invoke (ISPAGE) message for an MS and then (b) the border system receives a valid page response with global-challenge information (that is, COUNT, AUTHR, and RANDC) from the specified MS The responsibility of the process in this case is to authenticate the MS by sending an AUTHREQ message to the MS s home system If this is successful, the border system continues with the normal procedures If it is unsuccessful, the border system initiates local recovery procedures, which could involve sending an indication to the serving system that the MS is denied access in the IntersystemPage Return Result (ispage) message A very different form of the second task is initiated when (a) the border system receives an IntersystemPage2 Invoke (ISPAGE2) message for an MS and then (b) the border system receives a valid page response with global-challenge information (that is, COUNT, AUTHR, and RANDC) from
