System and method for location based push-to-talk
View Patent ↗A system and method are provided for establishing location-based push-to-talk communication groups. A location determining application is incorporated within a communication network for members of a push-to-talk group. This application may include global positioning satellite technology incorporated in mobile communication devices carried by the members, a triangulation application incorporated at a communications server, or an RFID application associated with the members. Location data obtained on the members is maintained in a database that is accessible to a communications server facilitating communication between the members. When a member initiates a push-to-talk communication, other members of the group are contacted based upon their locations. The communication can be selectively transmitted to either those within a pre-designated location, or outside of the pre-designated location.
1. A method of conducting communications, said method comprising:
establishing a push-to-talk group comprising a plurality of members, each member having a communication device for communicating through a communication network;
providing means for identifying locations of said members;
initiating a first push-to-talk communication by one member directed to the other members of the group;
determining the locations of the members at the time of the first communication;
selectively transmitting the first communication only to members that are presently located within a pre-designated location; and
establishing a time period for conducting communications between members of the push-to-talk group, wherein expiration of the time period corresponds to termination of the group defined for receiving the push-to-talk communications.
2. A method, as claimed in claim 1 , wherein:
said means for identifying includes at least one of (i) a global positioning satellite application incorporated in said communication devices, (ii) a triangulation application incorporated at a communications server for tracking locations of the communication devices, and (iii) an RFID application incorporated at the pre-designated location.
3. A method, as claimed in claim 1 , wherein:
the members of said group are selectively chosen by at least one member of the group, and said pre-designated location is selected by at least one member of the group.
4. A method, as claimed in claim 1 , further comprising the step of:
initiating a second push-to-talk communication by one member of the push-to-talk group, wherein those members receiving the second communication differ from the members receiving the first communication based on changed locations of the members.
5. A method of conducting communications, said method comprising:
establishing a push-to-talk group comprising a plurality of members, each member having a communication device for communicating through a communication network;
providing means for identifying locations of said members;
initiating a first push-to-talk communication by one member directed to the other members of the group;
determining the locations of the members at the time of the first communication;
transmitting the first communication only to those members not within a pre-designated location; and
wherein said means for identifying includes at least one of a triangulation application incorporated at a communications server for tracking locations of the communication devices and an RFID application incorporated at the pre-designated location.
6. A method, as claimed in claim 5 , wherein:
the members of said group are selectively chosen by at least one member of the group, and said pre-designated location is selected by at least one member of the group.
7. A method, as claimed in claim 5 , further comprising the step of:
initiating a second push-to-talk communication by one member of the push-to-talk group, wherein those members receiving the second communication differ from the members receiving the first communication based on changed locations of the members.
8. A method, as claimed in claim 5 , further comprising the step of:
establishing a time period for conducting communications between members of the push-to-talk group, wherein expiration of the time period corresponds to termination of the group defined for receiving the push-to-talk communications.
9. A method, as claimed in claim 5 , wherein:
an RFID application incorporated at the pre-designated location further comprises each member carrying an RFID tag/card that is read by one or more interrogating devices at a location of interest, the interrogating devices confirming the identity of each member carrying the tag/cards, and said information being transferred to a presence server such as by a wireless communication interface.
10. An apparatus for facilitating communications between members of a push-to-talk group communicating through a communications network, said apparatus comprising:
a communication server including a processor and a communications interface for communicating with a plurality of communication devices carried by the members;
programming instructions executed by said processor, said programming instructions including means for establishing active members of the push-to-talk group based upon geographic locations of the members;
a location determining application communicating with said processor for providing data inputs reflective of member locations;
a time period application for establishing a time period for conducting communications between members, wherein expiration of the time period corresponds to termination of the group defined for receiving the communications; and
wherein a push-to-talk communication initiated by a member to other members is selectively transmitted only to those other members that are presently located at a pre-designated location.
11. An apparatus, as claimed in claim 10 , further including:
an e-mail server communicating with said processor for establishing members of the push-to-talk group by identifying IP addresses/phone numbers of the members.
12. An apparatus, as claimed in claim 10 , wherein:
said location determining application includes at least one of (i) a global positioning satellite application incorporated in said communication devices, (ii) a triangulation application incorporated at the communications server for tracking locations of the communication devices, and (iii) an RFID application incorporated at the pre-designated location.
