Location sharing and tracking using mobile phones or other wireless devices

Methods and apparatus for limiting communication capabilities in mobile communication devices are disclosed. In one illustrative example, an operating variable of a mobile communication device is detected to be within one of a first range of values, a second range of values, and a third range of values. The mobile device operates in a full communication state if the operating variable is detected to be within the first range of values, a first limited communication state if the operating variable is detected to be within the second range of values, or a second limited communication state if the operating variable is detected to be within the third range of values. When receiving a communication request for establishment of a voice call or for communication of a user data message, the mobile device permits or prohibits the communication depending on the communication state, and preferably depending on whether the communication request is for a non-emergency or emergency communication. In one preferred embodiment, the operating variable is a temperature of the mobile device.

A wireless location system may include geolocation of a wireless device connected to Voice-over- Internet-Protocol (VoIP) adapter. The VoIP adapter may include a wireless transceiver or a wireless location determining receiver that facilitates the location of a wireless device connected to the VoIP adapter. The wireless transceiver or the location determining receiver may provide location information to an emergency dispatcher.

A system and method for providing location information to a public safety answering point from a softphone may include receiving, at a network access point, an emergency 911 call from the softphone. The emergency 911 call may be communicated to a public safety answering point. In response to a call connection message being received, an address location of the network access point to which the softphone is in communication in placing the emergency 911 call to the public safety answering point may be communicated in a type II caller ID data packet. The softphone may generate the type II caller ID data packet with the address location in a data field, such as a data field typically used for name information of a caller.
