Abstract: Methods, mobile stations and networks are provided that cause a packet data service reconnect to be performed automatically after the occurrence of an event triggering registration, even in some circumstances where such a data service reconnect would not normally occur. This avoids complications that can arise due to the packet data service being discontinued upon registration and the resulting inability to reach the mobile station.

Abstract: Methods for use in a mobile device configured to communicate in a wireless network is described. The mobile device detects whether a a temperature condition exists. When the temperature condition exists, the mobile device presents a visual indication which indicates that the mobile device is in an emergency communication state. The mobile device further operates to prohibit user-initiated communication requests for non-emergency telephone calls via the wireless network, but allows a user-initiated communication request for an emergency telephone call via the wireless network. When the temperature condition fails to exist, the mobile device operates to allow user-initiated communication requests for emergency and non-emergency telephone calls via the wireless network.

Abstract: An apparatus and method is provided for making use of black-list network information to make scanning more efficient in multi-mode mobile devices. When performing a scan for a network, if a network that is blacklisted is found, scanning is discontinued for any network that has the same radio access technology as the network that was found. Thus, excessive scanning that can be costly for the mobile device in terms of battery life and responsiveness to provide service, is avoided.
