User controlled location sharing during a communication
View Patent ↗During a telephone call, a party to the call may signal (by, for example, sending certain DTMF tones (a wish to provide his or her location to the other party to the call. The central office responds to this request by accessing a subscriber record for the communication line (e.g., subscriber loop) terminating at the requesting party and sending location information in the subscriber record to the other party to the call. Depending upon the technology available, the location information may be supplied in-band or on a parallel datapath.
1. A method for delivering call party location information, comprising:
after connection of a call and during pendency of the call between a first communication device and a second communication device, receiving a location information sharing request from said first communication device;
accessing a database providing location information for a plurality of communication devices and retrieving location information for said first communication device from said database; and
forwarding said retrieved location information for said first communications device.
2. The method of claim 1 wherein said forwarding comprises forwarding to said second communications device.
3. The method of claim 2 wherein said location information comprises a street address.
4. The method of claim 2 wherein said forwarding comprises forwarding to a data terminal associated with said second communications device.
5. The method of claim 4 wherein said associated data terminal is associated with said second communications device in a subscriber record for said second comminations device and further comprising accessing said second communications device subscriber record to ascertain said association prior to said forwarding.
6. The method of claim 4 wherein said location information comprises a universal resource locator (URL) forwarded to said data terminal.
7. The method of claim 1 wherein said first communication device is associated with a first identification number, wherein said database provides location information for a plurality of identification numbers and wherein said accessing comprises accessing said database with said first identification number for retrieving location information associated with said first identification number.
8. The method of claim 7 wherein said first identification number is a first telephone number.
9. The method of claim 7 wherein said first identification number is a first mobile identification number.
10. The method of claim 1 wherein said accessing comprising accessing a subscriber records database.
11. The method of claim 1 further comprising:
monitoring a first communications link terminated by said first communications device for said location information sharing request.
12. The method of claim 1 wherein said accessing a database comprises accessing a database of a telephony switch.
13. A method for delivering call party location information, comprising:
after connection of a call and during pendency of the call between a first telephone terminating a first wireline and a second telephone terminating a second wireline, receiving a location information sharing request from said first telephone on said first wireline;
accessing a subscriber records database having records for a plurality of subscribers, each record associating a subscriber with a wireline, and obtaining a record associated with said first wireline, said record comprising location information;
forwarding to said second telephone said location information.
14. A system for delivering call party location information, comprising:
means for, after connection of a call and during pendency of the call between a first communication device and a second communication device, receiving a location information sharing request from said first communication device;
means for accessing a database providing location information for a plurality of communication devices and retrieving location information for said first communication device from said database; and
means for forwarding said retrieved location information for said first communications device.
15. A computer readable medium containing instructions which, when performed by a processor of a central office, cause the central office to:
after connection of a call and during pendency of the call between a first telephone and a second telephone, receive a location information sharing request from said first telephone;
access a database providing location information for a plurality of telephones and retrieve location information for said first telephone from said database; and
forward said retrieved location information for said first communications device.
16. The computer readable medium of claim 15 which, when performed by said processor, further cause said central office to receive said location information sharing request by:
receiving tones; and
comparing said tones with a location sharing code.
17. The computer readable medium of claim 15 which, when performed by said processor, further cause said central office to access said database by:
address said database with a line card identifier terminating a subscriber loop for said first telephone.
18. The computer readable medium of claim 15 which, when performed by said processor, further cause said central office to access said database by:
address said database with an identification number associated with said first telephone.
