10. A portable device for use in a wireless network, the wireless network comprising at least one proximity service function for determining a state of proximity of at least a set of mobile devices in the wireless network with the portable device, the portable device comprising:
a processor;
a touch screen;
a memory comprising:
instructions, when executed by the processor, configured to automatically detect a touch event associated with the touch screen;
an emergency event module, when executed by the processor, configured to automatically determine whether the touch event corresponds to an emergency event;
a proximity detection module, when executed by the processor, configured, to in response to determination of the emergency event by the emergency event module, automatically contact the at least one proximity service function to determine dynamically, substantially in real-time, whether any mobile devices from the at least the set of mobile devices in the wireless network corresponding to any of a set of contacts of a user of the portable device is in a state of proximity with the portable device; and
a notification module, when executed by the processor, configured to, in response to determination of at least one mobile device in a state of proximity with the portable device, by the proximity detection module, automatically transmit a message to the at least one mobile device determined to be in the state of proximity with the portable device.
