Abstract
A cellular communication network has a mobile switching center (MSC) that maintains a GPS location data of a mobile handset referenced by a mobile identification number (MIN) and an electronic serial number (ESN) in addition to a geographic cell number in an HLR database for handsets operating in the network. The GPS location data of the handset may be used for efficient paging to a specific cell to route incoming calls to the handset, route emergency responder calls with the physical location of the handset and to program the handset with the handset transmission strength to the nearest cell tower In lieu of using triangulation algorithm.
Claims16
A mobile wireless cell phone device, operating as a part of a wireless communication network, comprising:
- a. the mobile wireless cell phone device has a GPS function that is configured to determine a GPS location data of the mobile wireless cell phone device;
- b. a registration request signal transmission management (RRSTM) logic operating in the mobile wireless cell phone device is configured to create a registration-request (R-R) record and embed the GPS location data of the mobile wireless cell phone device in the R-R record in addition to an international mobility equipment identifier (IMEI) data of the mobile wireless cell phone device in the R-R record;
- c. the RRSTM logic in the mobile wireless cell phone device is further configured to receive locations of the mobile wireless cell phone device at every elapsed time interval of a timer, periodically compute a distance between a current location of the mobile wireless cell phone device and an immediately prior location of the mobile wireless cell phone device, transmit from the mobile wireless cell phone device the R-R record with the GPS location data to the wireless communication network when the distance is greater than a threshold, and suppress transmission of the R-R record with the GPS location data to the wireless communication network when the distance is less than the threshold;
- and
- d. the mobile wireless cell phone device receives from the wireless communication network a transmission signal strength that is computed by a mobile switching center (MSC) in the wireless communication network, based on a distance, determined by the MSC, of a GPS location of the mobile wireless cell phone device to cell towers in a cell area in which the mobile wireless cell phone device is located.
A method for a mobile wireless cell phone device with a GPS receiver, operating as a part of a wireless communication network, comprising the steps, performed by the mobile wireless cell phone device of:
- a. determining a location of the mobile wireless cell phone device using the GPS receiver;
- b. creating by a registration request signal transmission management (RRSTM) logic in the mobile wireless cell phone device, operating in the mobile wireless cell phone device, a registration-request (R-R) record and embedding a GPS location data of the mobile wireless cell phone device in the record in addition to an international mobility equipment identifier (IMEI) data of the mobile wireless cell phone device in the record;
- c. receiving locations of the mobile wireless cell phone device at every elapsed time interval of a timer, periodically computing by the RRSTM logic in the mobile wireless cell phone device a distance between a current location of the mobile wireless cell phone device and an immediately prior location of the mobile wireless cell phone device, transmitting, by the RRSTM logic in the mobile wireless cell phone device, the R-R record with the GPS location data to the wireless communication network when the distance is greater than a threshold, and suppressing transmission of the R-R record with the GPS location data to the wireless communication network when the distance is less than the threshold;
- and
- d. receiving from the wireless communication network a transmission signal strength that is computed by a mobile switching center (MSC) in the wireless communication network, based on a distance, determined by the MSC, of a GPS location of the mobile wireless cell phone device to cell towers in a cell area in which the mobile wireless cell phone device is located.
A wireless cellular communication network, comprising:
- a HLR database configured to interface with a mobile switching center (MSC) of the wireless cellular communication network, wherein the HLR database maintains (i) a mobile identification number (MIN), (ii) an international mobility equipment identifier (IMEI) of a mobile device, and (iii) data fields for a latitude and a longitude for a GPS location data of the mobile device;
- the wireless communication network receives from the mobile device a registration request signal transmission which embeds the GPS location data of the mobile wireless cell phone device in the R-R record in addition to an international mobility equipment identifier (IMEI) data of the mobile wireless cell phone device in the R-R record when the mobile device has changed position from an immediate prior position exceeding a threshold distance;
- and
- the wireless communication network transmits to the mobile device, a transmission signal strength that is computed by MSC in the wireless communication network, based on a distance, determined by the MSC, of a GPS location of the mobile device to cell towers in a cell area in which the mobile device is located.
