INTRODUCTION
This Standard presents a recommended plan for the implementation of authentication enhancements for use in the Wireless Radiotelephone Service. Its intent is to describe the authentication enhancements so that the manner in which a system implements them may remain reasonably consistent from system to system.
The authentication enhancements include:
• Count Update after Handoff
• Obtaining subscriber profile before authentication on initial system access
• Handling of suspicious call originations
• Identify the Serving MSC when reporting the outcome of a requested authentication operation
• Handling of authentication capable mobile stations when the home system is not authentication capable
• Clarification and editorial correction of authentication procedures
• Miscellaneous authentication enhancements
