Methods and apparatuses for transmission of an alert to multiple devices
A system for exchanging GPS or other position data between wireless devices for purposes of group activities, child location monitoring, work group coordination, dispatching of employees etc. Cell phones and other wireless devices with GPS receivers have loaded therein a Buddy Watch application and a TalkControl application. The Buddy Watch application communicates with the GPS receiver and other wireless devices operated by buddies registered in the users phone as part of buddy groups or individually. GPS position data and historical GPS position data can be exchanged between cell phones of buddies and instant buddies such as tow truck drivers via a buddy watch server. Emergency monitoring services can be set up with notifications to programmable individuals in case an individual does not respond. Positions and tracks can be displayed. TalkControl simplifies and automates the process of joining talk groups for walkie talkie services such as that provided by Nextel.
1. A method comprising:
transmitting an alert to mobile communication devices that are in a selectively-defined group of one or more communication devices wherein
transmitting the alert is in response to not receiving a response to a periodic message transmitted to a first mobile communication device, the first mobile communication device including a GPS receiver adapted to generate GPS coordinates of the first mobile communication device,
the response requires input of a secret code from a user of the first mobile communication device,
the alert includes position of the first mobile communication device dependent on the GPS coordinates from the first mobile device, and
the alert comprises a timestamp associated with the position, the timestamp representing time at which the GPS coordinates were generated.
2. The method of claim 1 , wherein the alert comprises a prerecorded voice message.
3. The method of claim 1 , wherein:
the method further comprises
selectively activating a mode of the first mobile communication device that provides for tracking of location of the first mobile communication in dependence on way points, and
transmitting the way points from the first mobile communication device to a remote server for storage;
the activation of the mode is effective to trigger periodic transmission of said periodic message to the first mobile communication device; and
the transmitting of the alert is in response to not receiving a response to at least one instance of said periodic message.
4. The method of claim 3 , wherein the method further comprises identifying a number of attempts to establish contact with no response, the number of attempts being configurable to be greater than one, and wherein the transmitting of the alert is in response to not receiving a response after a number of consecutive instances of said periodic message equal to the number of attempts.
5. The method of claim 3 , wherein the alert comprises an email transmission sent to one or more email addresses associated with the group, the email transmission including text identifying a situation associated with the alert, at least one contact phone number, and an attachment of pertinent waypoints.
6. The method of claim 1 , wherein the alert comprises an email transmission sent to one or more email addresses associated with the group.
7. The method of claim 6 , wherein the email transmission comprises text describing a situation associated with the alert, a time indication, and at least one contact phone number.
8. The method of claim 1 , wherein the method further comprises maintaining a database that defines contacts and further, responsive to not receiving a response to a periodic message being transmitted to the first mobile communication device, querying the database for a subset of the contacts to which the alert is to be dispatched, and wherein the transmitting of the alert includes transmitting the alert to the subset of the contacts.
9. The method of claim 1 , wherein the method further comprises:
maintaining a database that defines subsets of the contacts listed in the database with respective, alternative alerts; and
identifying, responsive to an indication from the first mobile communication device, a specific subset of contacts associated with a selected one of the respective, alternative alerts; and
transmitting the selected one of the respective, alternative alerts to the specific subset of contacts.
10. The method of claim 1 , wherein the method further comprises maintaining a database that defines contacts and further, responsive to not receiving a response to a periodic message being transmitted to the first mobile communication device, identifying a subset of contacts listed in the database that are within a geographic zone proximate to the first mobile communication device, and wherein the transmitting of the alert includes transmitting the alert to the subset of the contacts.
11. A method comprising:
transmitting an alert to mobile communication devices that are in a selectively-defined group of one or more communication devices wherein
transmitting the alert is in response to not receiving a response to a periodic message transmitted to a first mobile communication device, the first mobile communication device including a GPS receiver adapted to generate GPS coordinates of the first mobile communication device,
the response requires input of a secret code from a user of the first mobile communication device,
the alert includes position of the first mobile communication device dependent on the GPS coordinates from the first mobile device, and
the method is embodied as a method of operating the first mobile communication device, wherein transmitting the alert includes receiving a command from a server to transmit the alert and responsively transmitting the alert, wherein responsive to the command from the server, the first mobile communication device is to generate current GPS coordinates and wherein the position is dependent on the current GPS coordinates.
