摘要： Example methods and apparatus to maintain call continuity are disclosed. A disclosed example method to authorize a request with service information (SI), including detecting whether the SI pertains to an existing Internet Packet (IP) flow, when the SI pertains to an existing IP flow, detecting whether the existing IP flow includes circuit switched (CS) media, and when the existing IP flow includes CS media, determining a response to the request independent of a CS media indicator.
