This paper describes two inventions that improve the operation of the IOS A1 Global Reset Procedure. The first invention provides a two-way handshake mechanism at both the beginning and end of the Global Reset Procedure; one of several benefits is a dramatic reduction in the execution time of the procedure, which increases overall system availability. The second invention provides a mechanism for either the Mobile Switching Center (MSC) or Base Station (BS) to immediately indicate if a fatal incompatibility is detected on the MSC-BS interface; early indication enables the MSC and BS to promptly initiate recovery procedures.
