1x EV-DO Roaming Issues
□ AN-AAA Interoperability
- IS-878 says “If terminal authentication is not used by an HRPD system,
the MN ID that is used by the PCF on the A10/A11 interface is determined
by other means beyond the scope of this specification”
- Without AN-AAA in the 1x EV-DO network, it may need change in PCF or
terminal and affect 1x EV-DO roaming
□ 1x EV-DO PRL Update
□ Terminal Interoperability
