Abstract

Methods, systems, computer-readable media, and apparatuses are presented for determining positions of mobile devices in a peer-to-peer network group. In some embodiments, a server receives information regarding a distance between a group owner mobile device and a client mobile device in a peer-to-peer network group. The server determines whether the distance between the group owner mobile device and the client mobile device exceeds a threshold distance. If the threshold distance is not exceeded, the server associates a position of the group owner mobile device with a position of the client mobile device.

First claim

What is claimed is:

1 . A method for determining a position of a client mobile device in a peer-to-peer network group, the method comprising:
determining a position of a group owner mobile device of the peer-to-peer network group, wherein the group owner mobile device supports at least one of communications between devices within the peer-to-peer network group or communications between a device within the peer-to-peer network group and devices outside of the peer-to-peer network group; receiving information about a distance between the group owner mobile device and the client mobile device; determining whether the distance between the group owner mobile device and the client mobile device exceeds a threshold distance; and determining, based on a determination that the distance between the group owner mobile device and the client mobile device does not exceed the threshold distance, the position of the client mobile device to be the determined position of the group owner mobile device.

2 . The method of claim 1 , wherein the group owner mobile device serves as an access point for the peer-to-peer network group.

3 . The method of claim 1 , wherein the distance between the group owner mobile device and the client mobile device is measured using a round trip time (RTT).

4 . The method of claim 1 , wherein determining the position of the group owner mobile device includes receiving a round trip time (RTT) between the group owner mobile device and each access point of a plurality of access points.

5 . The method of claim 1 , wherein determining the position of the group owner mobile device includes receiving received signal strength indicator (RSSI) data of signals associated with a plurality of access points, the RSSI data being measured by the group owner mobile device.

6 . The method of claim 1 , wherein determining the position of the group owner mobile device includes:
obtaining a heat map; and determining, using the heat map, the position of the group owner mobile device.

7 . The method of claim 1 , further comprising:
determining, based on a determination that the distance between the group owner mobile device and the client mobile device exceeds the threshold distance, the position of the client mobile device.

8 . The method of claim 7 , wherein determining the position of the client mobile device includes receiving a round trip time (RTT) between the client mobile device and each access point of a plurality of access points.

9 . The method of claim 7 , wherein determining the position of the client mobile device includes receiving received signal strength indicator (RSSI) data of signals associated with a plurality of access points, the RSSI data being measured by the client mobile device.

10 . The method of claim 7 , wherein determining the position of the client mobile device includes:
obtaining a heat map; and determining, using the heat map, the position of the client mobile device.

11 . The method of claim 1 , further comprising:
receiving an identifier of the group owner mobile device; and receiving an identifier of the client mobile device;

12 . The method of claim 11 , wherein at least one of the identifier of the group owner mobile device or the identifier of the client mobile device includes a media access control (MAC) address.

13 . The method of claim 11 , wherein at least one of the identifier of the group owner mobile device, the identifier of the client mobile device, or the distance between the group owner mobile device and the client mobile device is received in a beacon signal from the group owner mobile device.

14 . The method of claim 13 , wherein at least one of the identifier of the group owner mobile device, the identifier of the client mobile device, or the distance between the group owner mobile device and the client mobile device is included in an extended peer-to-peer information element of the beacon signal.

15 . A server comprising:
a processor; and a computer readable storage device communicatively coupled to the processor, wherein the computer readable storage device stores one or more programs executable by the processor, the one or more programs including instructions for:
determining a position of a group owner mobile device of a peer-to-peer network group, wherein the group owner mobile device supports at least one of communications between devices within the peer-to-peer network group or communications between a device within the peer-to-peer network group and devices outside of the peer-to-peer network group;
receiving information about a distance between the group owner mobile device and a client mobile device in the peer-to-peer network group;
determining whether the distance between the group owner mobile device and the client mobile device exceeds a threshold distance; and
determining, based on a determination that the distance between the group owner mobile device and the client mobile device does not exceed the threshold distance, a position of the client mobile device to be the determined position of the group owner mobile device.

16 . The server of claim 15 , wherein determining the position of the group owner mobile device includes receiving a round trip time (RTT) between the group owner mobile device and each access point of a plurality of access points.

17 . The server of claim 15 , wherein determining the position of the group owner mobile device includes receiving received signal strength indicator (RSSI) data of signals associated with a plurality of access points, the RSSI data being measured by the group owner mobile device.

18 . The server of claim 15 , wherein determining the position of the group owner mobile device includes:
obtaining a heat map; and determining, using the heat map, the position of the group owner mobile device.

19 . The server of claim 15 , wherein the one or more programs further include instructions for:
determining, based on a determination that the distance between the group owner mobile device and the client mobile device exceeds the threshold distance, a position of the client mobile device.

20 . The server of claim 19 , wherein determining the position of the client mobile device includes receiving received signal strength indicator (RSSI) data of signals associated with a plurality of access points, the RSSI data being measured by the client mobile device.

21 . The server of claim 19 , wherein determining the position of the client mobile device includes:
obtaining a heat map; and determining, using the heat map, the position of the client mobile device.

22 . A non-transitory computer readable medium including machine-readable instructions stored thereon for determining a position of a client mobile device in a peer-to-peer network group, the instructions comprising:
determining a position of a group owner mobile device of the peer-to-peer network group, wherein the group owner mobile device supports at least one of communications between devices within the peer-to-peer network group or communications between a device within the peer-to-peer network group and devices outside of the peer-to-peer network group; receiving information about a distance between the group owner mobile device and the client mobile device; determining whether the distance between the group owner mobile device and the client mobile device exceeds a threshold distance; and determining, based on a determination that the distance between the gro
