Abstract

Systems, methods, and devices for managing termination of an active communication session in a wireless communication device. A processor of the wireless communication device may receive an instruction to terminate a communication session. The processor may determine whether an emergency communication status of the wireless communication device indicates that the communication session should not be terminated. The processor may block the instruction to terminate the communication session in response to determining that the emergency communication status indicates that the communication session comprises an emergency communication session.
