First Claim
Patent Images
1. A position-discovery method for a mobile device, said method comprising:
- receiving messages from a plurality of originating points;
determining a most prominent originating point, wherein said most prominent originating point is a member of said plurality of originating points that originates a greatest quantity of said messages in a set of recently received messages; and
determining a position of said mobile device based on, at least, position data specific to said most prominent originating point wherein said position data is provided in a message from said most prominent originating point.

Abstract
A position-discovery method is provided for a mobile device equipped with non-wired short-range communication means for receiving locally-transmitted messages. At least some of the messages include position data concerning the originating point of the message. The device determines its position as being that of the most common originating point for messages in a set of most recently received messages.

5. A position-discovery method for a mobile device, comprising:
-
participating in a process for locally diffusing information for presentation to users of mobile devices, wherein said process involves propagating said information in messages passed from a first device to a second device by non-wired short-range communication means of the said first and second devices, a number of copies of a message in propagation initially tending to increase due to propagation activities of receiving devices and then tending to decrease as said receiving devices implement propagation limitation measures for said message, wherein at least some of said messages include position data specific to originating points of said messages; and
processing a set of recently received messages to determine a position of said mobile device based on at least, position data of a most prominent originating point, wherein said most prominent originating point is a member of said originating points that originates a greatest quantity of said messages in said set. - View Dependent Claims (6, 7, 8)

9. A mobile device comprising:
-
a short-range wireless receiver for receiving messages, wherein at least some of said messages include position data specific to originating points of said messages;
an originating-point monitor for determining originating points of a set of recently received messages; and
a location determination unit for processing said set of recently received messages to determine a position of said mobile device based on, at least, position data of a most prominent originating point, wherein said most prominent originating point is a member of said originating points that originates a greatest quantity of said messages in said set. - View Dependent Claims (10, 11, 12)
