Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
63 words
A position-discovery method for a mobile device equipped with non-wired short-range
communication means for receiving locally-transmitted messages, at least some of the
messages including position data concerning the originating point of the message, the
device determining its position by using position data from a set of most recently received
messages taking account of the relative prominence of the originating points of those
messages.
Claim 2
Dependent Claim
31 words
A method according to claim 1, wherein the device determines its position as being that
of the most common originating point for messages in said set of most recently received
messages.
Claim 3
Dependent Claim
34 words
A method according to claim 1, wherein the device determines its position as a
weighted average of the positions of the originating points of the messages in said set of
most recently received messages.
Claim 4
Dependent Claim
16 words
A method according to claim 1, wherein said set is defined by a receiving time
window.
Claim 5
Independent Claim
90 words
A method according to any one of the preceding claims, wherein the mobile device
participates in a process for locally diffusing information for presentation to users of
mobile devices, this process involving propagating the information from an originating
point in messages passed from device to device by non-wired short-range communication
means of the devices, the number of copies of a message in propagation initially tending to
increase due to the propagation activities of the receiving devices and then dying away as
the devices implement propagation limitation measures for the message.
Claim 6
Dependent Claim
108 words
A mobile device for locally diffusing information in messages to other devices for
presentation to their users, at least some of the messages including position data
concerning the originating point of the message; the mobile device comprising: a message store; a short-range wireless receiver for receiving said messages; an originating-point monitor for monitoring the originating points of a set of most
recently received messages; and a location determination unit for determining the position of the device by using
position data from said set of most recently received messages and taking account of
the relative prominence of the originating points of those messages as monitored by
the originating-point monitor.
Claim 7
Dependent Claim
39 words
A device according to claim 6, wherein the location determination unit is operative to
determines the position of the device as being that of the most common originating point
for messages in said set of most recently received messages.
Claim 8
Dependent Claim
42 words
A device according to claim 6, wherein the location determination unit is operative to
determines the position of the device as a weighted average of the positions of the
originating points of the messages in said set of most recently received messages.
Claim 9
Dependent Claim
21 words
A device according to claim 6, wherein said set is defined by a receiving time window
preset in the originating-point monitor.
