摘要： Services for a personal electronic device are provided through which a form of background processing or multitasking is supported. The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. By way of example, inactive network applications (e.g., VOIP applications) may be placed in a suspended state until a message is received targeting the application (e.g., an incoming phone call or a heartbeat needed message). The user application may be placed into the background state to respond to the message and then returned to the non-active state (e.g., if the message was a heartbeat needed) message or to the foreground state if appropriate (e.g., the user elects to answer the incoming call).
