Communication based on geographical region
In some embodiments, a server establishes communication with user devices; the server receives location data identifying a location of each user device; the server determines a geographical region based on the location of each user device, each geographical region being different for user devices not at the same location; the server receives an audio stream from the first of the user devices; the server determines which of the other user devices are within the geographical region of the first user device; and the server transmits the audio stream to the other user devices that are within the geographical region of the first user device. In some embodiments, the server creates altered audio streams based on the distances between user devices. In some embodiments, the server changes the number of the other user devices that are within the geographical region of the first user device.

changing, by the server, a number of the other user devices that are within the geographical region of the first user device by changing the area of the geographical region based on a level of communication traffic for audio streams received from the other user devices;
wherein:
the changing of the number of the other user devices that are within the geographical region of the first user device includes at least one of: 1) decreasing, by the server, the number of the other user devices that are within the geographical region of the first user device by decreasing the area of the geographical region, and 2) increasing, by the server, the number of the other user devices that are within the geographical region of the first user device by increasing the area of the geographical region;
the decreasing of the area of the geographical region is in response to the number of the other user devices that are within the geographical region of the first user device being above a maximum threshold; and
the increasing of the area of the geographical region is in response to the number of the other user devices that are within the geographical region of the first user device being below a minimum threshold.
2. The method of claim 1 , wherein changing the number of the other user devices that are within the geographical region of the first user device includes at least one of: 1) decreasing, by the server, the number of the other user devices that are within the geographical region of the first user device by decreasing the area of the geographical region, and 2) increasing, by the server, the number of the other user devices that are within the geographical region of the first user device by increasing the area of the geographical region.
3. The method of claim 2 , wherein:
the decreasing of the area of the geographical region decreases a radius of the geographical region; and
the increasing of the area of the geographical region increases a radius of the geographical region.
4. The method of claim 1 , further comprising:
for each user device, determining, by the server, the geographical region with that user device at a center of the geographical region.
5. The method of claim 1 , further comprising:
for each user device, determining, by the server, the geographical region with boundaries based on geographical features.
6. The method of claim 1 , further comprising:
for each user device, repeatedly determining, by the server, the geographical region, the geographical region changing as that user device changes location; and
repeatedly determining, by the server, a set of the other user devices that are within the geographical region of the first user device, the set of the other user devices changing as the geographical region of the first user device changes.
7. The method of claim 1 , further comprising:
for each user device with a changing location, determining, by the server, a group of user devices based on i) the geographical region of that user device, and ii) a history of locations of that user device; and
transmitting, by the server, an audio stream of the first user device to the other user devices that are within the group of user devices for the first user device.
8. The method of claim 7 , further comprising:
for each user device for which the history of locations indicates that it is moving, determining, by the server, the group of user devices further based on a direction of movement of that user device.
9. The method of claim 8 , further comprising:
for each user device that is moving, determining, by the server, the group of user devices further based on a direction of movement of the other user devices.
10. The method of claim 8 , further comprising:
for each user device that is moving, determining, by the server, the group of user devices further based on a direction of movement of the other user devices relative to the direction of movement of that user device.
11. The method of claim 8 , further comprising:
for each user device that is moving, determining, by the server, the group of user devices further based on a direction of movement of that user device and of the other user devices relative to a geographical feature.
12. The method of claim 7 , further comprising:
for each user device for which the history of locations indicates that it is moving, determining, by the server, the group of user devices further based on a speed of movement of that user device.
13. The method of claim 1 , further comprising:
for each user device, determining, by the server, a group of user devices based on i) the geographical region of that user device, and ii) that user device and a set of the user devices travelling on a same route; and
transmitting, by the server, an audio stream of the first user device to the other user devices that are within the group of user devices for the first user device.
14. The method of claim 1 , further comprising:
for each user device, determining, by the server, a group of user devices based on the geographical region of that user device, the other user devices that are within the geographical region of that user device being a subset of the other user devices, the subset of the other user devices being in the group of user devices for that user device, and that user device being in the groups of user devices for the subset of the other user devices; and
for each user device, transmitting, by the server, audio streams received from that user device to the other user devices that are in the group of user devices for that user device.
15. The method of claim 1 , further comprising:
transmitting, by the server, an audio stream of the first user device to the other user devices that are within the geographical region of the first user device in near real-time.
16. A method comprising:
establishing, by a server, communication with user devices, the user devices including a first user device and other user devices;
for each user device, receiving, by the server, location data identifying a location of that user device;
for each user device, determining, by the server, a geographical region based on the location of that user device, the geographical region having an area;
for each user device, determining, by the server, the other user devices that are within the geographical region of that user device;
receiving, by the server, audio streams from at least one of the other user devices that are within the geographical region of the first user device;
transmitting, by the server, the audio streams to the first user device; and
changing, by the server, a number of the other user devices that are within the geographical region of the first user device by changing the area of the geographical region;
wherein:
the changing of the number of the other user devices that are within the geographical region of the first user device includes at least one of: 1) decreasing, by the server, the number of the other user devices that are within the geographical region of the first user device by decreasing the area of the geographical region, and 2) increasing, by the server, the number of the other user devices that are within the geographical region of the first user device by increasing the area of the geographical region;
the decreasing of the area of the geographical region is in response to the number of the other user devices that are within the geographical region of the first user device being above a maximum threshold; and
the increasing of the area of the geographical region is in response to the number of the other user devices that are within the geographical region of the first user device being below a minimum threshold.
