Embodiment Construction

[0018] now refer to figure 1 , which generally illustrates a mobile handset 118 capable of determining location. Mobile handset 118 is being used in geographic area 100 . Geographical area 100 includes coverage area 103 . A coverage area is an area served by a mobile telephone system. Areas outside the coverage area are called no-service areas. Some base stations 105 , 107 , 109 , 112 , 114 are located inside the coverage area 103 . These base stations are fixed devices with which mobile handsets send and receive to complete mobile calls. Typically, the coverage area 103 will contain at least one base station compatible with the particular mobile telephone system, while the no-service area will generally not contain any base stations compatible with the particular mobile telephone system.

[0019] The mobile handset 118 is displayed in a first location 120 . Adjacent to the first location 120 is a location 126 where an emergency has occurred. The emergency could be a tr...

Abstract

The location capable mobile handset allows the user to provide a call recipient with the location of an unsuccessful attempted emergency call. In one specific example, the call may be an E911 call to a PSAP dispatcher. Additionally, the call may be to a towing service, or to a family member or friend to request assistance. The call may be any call that a mobile handset user wants to send location information to the party that has been called. Returning to the E911 call example, the location information reported to dispatcher can include the location of initial E911 call, current location during a successful E911 call, or ground track information from the initial location to the current location. When an E911 call is unsuccessfully attempted, the mobile handset stores the location of the mobile handset at that time. This information can later be transmitted when the mobile handset is in a coverage area. Additionally, the mobile handset can auto-dial 911 upon entering a service area after an unsuccessful E911 attempt. Alternately the user can be prompted to initiate an E911 call when the mobile handset enters a service area.

Description

technical field [0001] The present invention generally relates to communication devices, and more particularly to a mobile handheld communication device. Background technique [0002] Some countries have official national emergency phone numbers. For example, in the US and Canada, that number is 911. When 911 is dialed, the user is connected to a Public Safety Answering Point (PSAP) dispatcher. The emergency dispatcher sends the emergency call to local medical, fire and law enforcement agencies handling the emergency. Currently, when a telephone call is made using a wired telephone, the telephone number and address information is usually automatically reported to the dispatcher. [0003] Basic wireless 911 service requires that 911 calls from both subscribers and non-subscribers be routed to the PSAP using whatever service is available. However, basic wireless 911 service does not provide dispatchers with location information like a wired phone does. The Federal Communi...
