Abstract: A wireless device may include a digital receiver and a digital transmitter, and a controller configured to control the digital receiver to receive signals and the digital transmitter to transmit signals, and further configured to receive a registration rejection from a first roaming mobile network while roaming, add the first roaming mobile network to a list of forbidden mobile networks, register with a second roaming mobile network and receiving an operator list of mobile networks from a home mobile network, and attempt to register with the first roaming mobile network based on a ranking of mobile networks in the operator list.

Abstract: Embodiments described herein relate generally to a user equipment (“UE”) that is to receive emergency communication. The UE may be camped with limited service on a wireless network that is associated with a visited mobile switching circuit (“MSC”). While camped in limited service, the UE may transmit a location update request to the visited MSC that indicates the UE is to receive emergency communication while camped with limited service on the wireless network. Accordingly, the visited MSC may update a visitor location registry and a home location registry. Thereafter, when an emergency service attempts to contact the UE, the UE may be reached even while camped with limited service.

Abstract: Examples of systems and methods for advanced call notification are generally described herein. A system may include a communication module to receive an indication from a remote device, the indication including information identifying the remote device and an urgency value and receive a call initiated by the remote device. The system may include a processing module to determine the urgency value indicates the call is urgent, and in response to determining the call is urgent, direct the communication module to connect to the remote device.
