Abstract
Wireless telephone networks, such as cellular, PCS networks, and other mobile radio services networks provide 911 or similar emergency calling services between mobile stations and a public safety answering point (PSAP). In emergency situations, the caller often will not be satisfied with the quality of the link to the PSAP, for any of a variety of subjective reasons. In such a case, the caller ends the first emergency call and initiates another emergency call. In accord with the invention, if the caller initiates the second emergency call within a predetermined interval from the first call, the mobile station will select an alternate operating system of the network for the second call. For example, if the first call utilized the A-side cellular carrier, the handset will select a B-side or PCS carrier for the second call. The handset also may select a different technology, e.g. analog instead of the normally preferred digital, for the second emergency call. The expectation is that conditions will be different on the alternate operating system and provide a quality of service that the emergency caller subjectively finds more acceptable.
