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.

Abstract: Data connection management in a mobile device is achieved by selectively allowing and denying data access to applications installed on the mobile device based on certain conditions, for example, when the mobile device is roaming, when the battery power is low, or when the data usage has exceeded a limit

Abstract: Methods and apparatus for performing a search procedure include determining, by a processor, that a current location identifier of a current network is the same as a stored location identifier corresponding to a transition to or from a home network. The methods and apparatus further include initiating the search procedure based on determining that the current location identifier is the same as the stored location identifier.

Abstract: Embodiments of the present invention provide devices, methods, and systems for use in emergency call situation. For example, in one embodiment, a mobile wireless device transmits a registration message upon an end of an emergency callback mode, which takes place after an emergency call made while the mobile device is in airplane mode, to ensure that the network is aware of the active status of the mobile device. This way, the user of the mobile device can receive all incoming calls after the cessation of the emergency callback mode, relieving the user of the inconvenience of being unaware of their inability to receive incoming calls. Other aspects, embodiments, and features are also claimed and described.

Abstract: A method for playing a local ringback tone is disclosed. A second party device is called from a calling party device. An alert message indicating that the calling party device is to play a network ringback tone is received. It is determined whether to play a pre-stored local ringback tone instead of the network ringback tone. The local ringback tone or the network ringback tone is played based on the determination. At any time before call connection or call release, the local ringback tone and the network ringback tone are switched between based on user input.
