Abstract

An emergency call originates from a cellular radiotelephone (20) and communicates through one of A-side and B-side cellular systems. Upon receipt of the call, the cellular radiotelephone (20) is assigned a temporary substitute Mobile Identification Number (MIN) (100) by the receiving A-side or B-side cellular system MTSO (33). Upon termination of the emergency call, a call-back to the cellular radiotelephone (20) is routed to both of the A-side and B-side MTSOs (100), using the substitute MIN (100), by the Public Switched Telecommunications Network (36). Both A-side and B-side MTSOs (100) issue a page order message to cellular radiotelephone (20) by transmitting to the MIN (74). Paging order confirmation messages (78), conveying the MIN (74), are evaluated for a match with a unique Electronic Serial Number (76).
