Abstract
Various embodiments include methods and wireless devices implementing such methods for detecting when the wireless device is operating in a limited service state (LSS) mode, transitioning from operating in LSS to satellite-based SOS mode in response to the wireless device operating in LSS mode, and sending a text message or initiating a voice call using the satellite-based SOS mode.
Claims28
A wireless device, comprising:
- a processor configured to:
- detect the wireless device is operating in a limited service state (LSS) mode;
- transition from operating in LSS to satellite-based SOS mode in response to the wireless device operating in LSS mode;
- transmit a first text message to initiate polling of a satellite in communication with the wireless device for incoming text messages or voice calls from the wireless device, wherein the first text message is an empty text message;
- receive a response from the satellite to prompt the wireless device to transmit data;
- and
- send a second text message or initiate a voice call using the satellite-based SOS mode.
A method for communicating via a satellite communication system by a wireless device, comprising:
- detecting when the wireless device is operating in a limited service state (LSS) mode;
- transitioning from operating in LSS to satellite-based SOS mode in response to the wireless device operating in LSS mode;
- transmitting a first text message to initiate polling of a satellite in communication with the wireless device for incoming text messages or voice calls from the wireless device, wherein the first text message is an empty text message;
- receiving a response from the satellite to prompt the wireless device to transmit data;
- and
- sending a second text message or initiating a voice call using the satellite-based SOS mode.
A wireless device, comprising:
- means for detecting when the wireless device is operating in a limited service state (LSS) mode;
- means for transitioning from operating in LSS to satellite-based SOS mode in response to the wireless device operating in LSS mode;
- means for transmitting a first text message to initiate polling of a satellite in communication with the wireless device for incoming text messages or voice calls from the wireless device, wherein the first text message is an empty text message;
- means for receiving a response from the satellite to prompt the wireless device to transmit data;
- and
- means for sending a second text message or initiating a voice call using the satellite-based SOS mode.
A non-transitory processor-readable medium having stored thereon processor-executable instructions configured to cause a processor of a wireless device to perform operations comprising:
- detecting when the wireless device is operating in a limited service state (LSS) mode;
- transitioning from operating in LSS to satellite-based SOS mode in response to the wireless device operating in LSS mode;
- transmitting a first text message to initiate polling of a satellite in communication with the wireless device for incoming text messages or voice calls from the wireless device, wherein the first text message is an empty text message;
- receiving a response from the satellite to prompt the wireless device to transmit data;
- and
- sending a second text message or initiating a voice call using the satellite-based SOS mode.
