Abstract:
A user who loses or has stolen his wireless telephone can access an Internet server that prompts the phone to send to the server (and, hence, the user) the GPS location of the phone. Also, when a wireless telephone reaches a low voltage state, indicating the imminent loss of the ability to call the phone to cause it to ring as a location aid, the phone automatically sends its last GPS location to the server.

Description:
I. FIELD OF THE INVENTION 
       [0001]    The present invention relates generally to systems and methods for obtaining the location of a wireless telephone using an Internet server. 
       II. BACKGROUND OF THE INVENTION 
       [0002]    Wireless telephones are becoming increasingly prevalent in today&#39;s society. They often contain important data such as personal schedules and phone numbers of friends and family. Reliance on the data stored in wireless telephones has become significant, yet few users ever backup their data to a secondary location. Misplaced or stolen wireless telephones can result in loss of important and sometimes irretrievable data. Moreover, if the wireless telephone is stolen by a malicious thief, data accessible to the theft on the wireless telephone such as telephone numbers of friends and family may compromise individual security. 
         [0003]    As understood herein, if a wireless telephone is stolen from a user, initiating the ring function to locate the wireless telephone based on the source of the sound is ineffective in locating the phone because it will be outside the audible range of the user. Indeed, once the theft occurs, it is nearly impossible to discover the wireless phones location. There is currently no method for finding the wireless telephone once it has been stolen. 
         [0004]    Moreover, telephones can be misplaced and are difficult to locate and, once the voltage in the battery dwindles, not enough remains to operate the wireless telephone. At this point the user cannot call the telephone to trigger the ring function and thereby allow the attentive user to locate the wireless telephone based on the source of the sound generated by the wireless phone. Thus, once the wireless telephones battery lacks the necessary voltage to remain operational, thereby preventing activation of the ring function, the wireless telephone cannot be located by causing it to ring. There is currently no solution to this issue either. 
         [0005]    With these critical observations in mind, the present invention is provided. 
       SUMMARY OF THE INVENTION 
       [0006]    A method is disclosed for locating a wireless telephone that includes a transceiver and a position receiver. The method includes actuating an Internet server to establish communication with the wireless telephone. The server prompts the telephone to use the transceiver to send a location from the position receiver to the server. The location is provided to a user by means of a website hosted by the server. 
         [0007]    The transceiver can be a wireless telephony transceiver, and the server can communicate with the wireless telephone using a telephone number of the telephone. Also, a short range wireless Internet transceiver can be provided in the phone, and the server can communicate with the wireless telephone using an IP address of the telephone. 
         [0008]    In another aspect, a wireless telephone has a wireless telephony transceiver, a position receiver outputting a geographic position signal, and a processor. The processor responds to a command from an Internet server to send the geographic position signal to the server. 
         [0009]    In yet another aspect, a wireless telephone has a wireless telephony transceiver, a position receiver outputting a geographic position signal, a battery, and a processor. The processor automatically activates the transceiver to send the geographic position signal when a voltage of the battery satisfies at least one criterion, e.g., when the battery voltage reaches a low voltage threshold. 
         [0010]    The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0013]    Beginning with  FIG. 1 , a non-limiting system diagram for a wireless telephone is shown. The wireless telephone  10  can be owned by a user who has access to an Internet-enabled computer  11  for purposes to be shortly disclosed. 
         [0014]    As shown in  FIG. 1 , the telephone  10  has a display  12  which is used to display data to the user. Accompanying the display  12  is a keypad  14  which allows the user to input data such as a telephone number or text message. The data is managed by at least one processor  16 . The processor  16  includes the capability to execute logic, including the logic set forth in  FIG. 2  and  FIG. 3 . The wireless telephone  10  also has memory  18  that is used to store data and has at least one battery  20  that supplies the wireless telephone  10  with the voltage needed to operate. A wireless transceiver  22  is embodied on the wireless telephone  10 . The wireless transceiver  22  transmits and receives data, such as text messages and telephone calls. The wireless transceiver  22  can be, but is not limited to, a CDMA, TDMA, or GSM transceiver. 
         [0015]    A Global Positioning System (GPS) receiver  24  may also be embodied on the wireless telephone  10 . The GPS receiver  24  receives data that identifies the current latitudinal and longitudinal coordinates of the wireless telephone  10 . All of the above components are housed in a single portable hand held housing, currently designated as the wireless telephone  10 . A short range Internet transceiver  25  such as a Wi-Fi transceiver may also be provided in the telephone  10  for purposes to be shortly disclosed. 
         [0016]    A website  26  is shown separately from the wireless telephone  10 . The website  26  can be constructed and maintained on a host server  28 . As more fully discussed below, the website  26  informs the user of the location of the lost or stolen wireless telephone  10 . The website  26  does this based on the latitudinal and longitudinal coordinates received by the GPS receiver  24 , transmitted by the wireless transceiver  22  and received by the website  26 . 
         [0017]    Moving to  FIG. 2 , the process for locating the wireless telephone  10  when misplaced or stolen is shown. Beginning the logic at block  30 , a user, by means of the computer  11 , logs on to the website  26 . The website  26  is capable of interacting with the wireless telephone  10  through the logic discussed below. 
         [0018]    Specifically, at block  32  the user initiates the process for determining the location of the wireless telephone  10  by accessing the website  26  and providing the telephone number and/or IP address of the phone  10 , and in response the website  26  establishes communication with the wireless telephone  10 . Communication may be established through the Internet transceiver  25  and a browser executed by the wireless telephone processor  16  using the IP address of the telephone, and/or communication may be established through the transceiver  26  using the telephone number of the telephone. In either case, the server prompts the telephone to relay back the location of the telephone. 
         [0019]    Accordingly, at block  34  the GPS receiver  24  determines the current latitudinal and longitudinal coordinates of the wireless phone  10 . Moving to block  36 , the current latitudinal and longitudinal coordinates of the wireless telephone  10  are transmitted to the website  26  by the wireless transceiver  22  or over the short range wireless Internet link. Concluding at block  38 , the user acquires the current latitudinal and longitudinal coordinates sent by the wireless telephone  10  by accessing the server, which provides the coordinates, in some implementations by showing the telephone location on a map. 
         [0020]    Now turning to  FIG. 3 , the logic for determining the last known GPS coordinates when the wireless telephone  10  reaches the low voltage threshold is shown. The low voltage threshold is predetermined so that when the threshold is reached, the logic proceeds as follows. It is to be understood that in a non-limiting implementation the low voltage threshold is established based on any appropriate criterion, e.g., the voltage below which the phone has insufficient transmission power or the voltage that is just high enough to permit the processor to execute the logic before it can no longer function. 
         [0021]    Beginning at block  40 , the logic determines the voltage remaining in the battery  20 . At decision diamond  42 , the logic determines whether the remaining battery voltage in the battery  20  has reached the low voltage threshold. If the battery has not reached the low voltage threshold, the logic reverts back to block  40  and the process loops. It is to be understood that the process may immediately begin again, or it may begin at predetermined time intervals. 
         [0022]    If the battery voltage equals the low voltage threshold, at block  44  the logic determines the current latitudinal and longitudinal coordinates through GPS receiver  24 . Alternatively, the logic accesses the latest GPS coordinates stored in the wireless telephone  10  memory at block  44 . The logic then concludes at block  46  at which the transceiver  22  sends the most recent coordinates of the wireless telephone  10  to the predetermined website  26 . At any time thereafter, the website  26  can be accessed by the user to determine the last known location of the wireless telephone  10 . Alternatively, the website  26  may also automatically generate an alert such as an email, which will be sent to the user and will identify the last known location of the wireless telephone  10 . 
         [0023]    The present invention recognizes that while in the low voltage threshold, the location of the cell phone may change. In light of this, it is to be understood that the logic set forth in  FIG. 3  may reoccur upon the elapse of a predetermined period of time. This is necessary to receive the cell phone&#39;s most recent location prior to completely shutting off due to low voltage. More specifically, because the wireless phone  10  may stay within the low voltage threshold for more than a momentary period of time, e.g. it may remain within the low voltage threshold for several minutes during which period the location of the phone might change, it is desirable that the logic of  FIG. 3  repeat periodically while the phone  10  is within the low voltage threshold to ensure that the user will have the most accurate GPS coordinates feasible. 
         [0024]    The telephone  10  can execute the logic of one or both of  FIGS. 2 and 3 . 
         [0025]    While the particular SYSTEM AND METHOD FOR OBTAINING LOCATION OF WIRELESS TELEPHONE FROM INTERNET SERVER is herein shown and described in detail, it is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
