Abstract

This invention provides a mechanism to dynamically update the IOS Revision Level negotiated between a Mobile Switching Center (MSC) and Base Station (BS) without incurring a system outage, which is presently caused by the Global System Reset in CDMA systems. While the system is fully operational, this method can be used to renegotiate the IOS Revision Level (i.e., either upgrade to a higher IOS protocol revision level or back out of the current IOS version to an earlier revision level).
