Abstract
A method and system to facilitate an inter-system CDMA multi-mode multi-pilot hard handoff is,provided. Reference target cell information consisting of reference target cell designations and their attributes are passed between the BS and MSC interfaces and between the serving MSC and target MSC interfaces. This invention enhances the ANSI-41 and CDG IOS A-Interface specifications to include reference target cell information. The target MSC processes the handoff request using the reference target cell information. The target MSC uses the reference target cell information to perform the handoff and other functions such as handoff retries, load balancing, and target screening. This increases the reliability of inter-system CDMA multi-mode multi-pilot hard handoffs.
