A. LNS VOCABULARY
A. 1. LNS Mobile
A physical, portable computer such as a smart mobile phone that
can send a virtual or current physical Location (Latitude,
Longitude, Altitude) and Cardinal Direction via a defined
protocol over HTTP/1.1 in a TCP/IP-based network connection
to an LNS Server.
A. 2. LNS Server
A logical server computer such as a “1U rack” with CPU, RAM and
disk, virtual memory, a process that acts on input variables and
processes this information in virtual memory, and a process that
returns information to a Device when the input parameters
triggers an Action based on the logical rules programmed by an
Agency.
A. 3. LNS Device
A physical sensor output device such as a television screen,
audio speaker, or an input device such as a video or audio
recoder that receives information from a Server and that
executes an Action that is recognisable by the Mobile.
A. 4. LNS Action
An event that is triggered by pre-programmed rules that
is based on input sensor parameters from a Mobile sent
to a Server over TCP/IP network, processed by the
Server and sent to a Device over TCP/IP network to
execute something that is recognisable to the Mobile.
A. 5. LNS Agency
Auto-algorithm writer or programmers that is using the
System to write programs that uses the elements in the
System to trigger Action on a Device recognized by the
Mobile.
A. 6. LNS Ask
A provider of material, virtual or gratis products
available for sale in the moment when a Action was
triggered on a Device to a Mobile.
A. 7. LNS Bid
A bidder of an Action that triggers an Action on a Device.
A. 8. LNS Match
Occurs when an Agency has programmed a rule that
triggers an Action for a Seller by Bidder on a Device
recognizable to Mobile that agrees to buy from the
Seller.
B. LNS PROCESSES
B. 1. LNS Mobile
The primary input sensor moving in space, direction and time and
that provides sensor output parameters to the Server such as
Output Variables to Server.
: ipaddress
Example output values: (“129.1.178.188”)
: sessionid
Example output values: (“e1ec37ec-b326-464d-8993-cbc9bf657ce4”)
: GPS Latitude
Example output values: (“10.362”)
: GPS Longitude
Example output values: (“32.102”)
: GPS Altitude
Example output values: (“0”, “5m”, “10m”, “15m”, “500m”, “3000m”, “10000m”)
: Cardinal direction Example output values:
(“North”,”NorthEast”,”NorthWest”,”South”, “SouthEeast”,
“SouthWest”, “E”, “W”)
B. 2. LNS Server
The Server is the input request and response engine that processes input
sensor parameters from Mobile and outputs a response to the Device based
on logical Action event triggers programmed by the Agency, and sends the
Action event trigger to the Device.
B. 2. a. LNS Time Server <-> Mobile/Device
The System Time is UTC and Server request and Response is logged.
B. 2. b. LNS Connection Server <-> Mobile
Example:
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 lns-server:80 129.01-178-188.mobile:62 ESTABLISHED
B. 2. c. LNS Connection Server <-> Device
Example:
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 lns-server:80 211.90-149-168.device:62 ESTABLISHED
B. 2. d. LNS Input Handler Server Process
Example:
lnsd 2670 0.0 0.1 24616 5132 pts/1 Ss 23:31 0:00 lns-mobile-handler
B. 2. e. LNS Output Handler Server Process
Example:
lnsd 2671 0.0 0.1 24616 5132 pts/1 Ss 23:31 0:00 lns-device-handler
B. 2. f. LNS Output Handler Server Process
The Server Input Process logs incoming input sensor from a
Mobile parameters and the Actions.
The Server will use pre-computed approximation tables such as
the following.
Example:
Apr 13 22:40:55 lns-mobile-handle:In(“129.1.178.188,10.362,32.102,5,NW)
: physical distance between Mobile and Device
: cardinal direction (“North”,”South”,”East”,”West”)
between Mobile and Device
B. 2. g. LNS Output Handler Server Process
Apr 13 22:40:55 lns-device-handler
Apr 13 22:40:55 Action “CB_LCD_42_NW” “15s” “htc-NO.avi”
B. 3. LNS Device
The Device is the output sensor that provides an Action recognizable to
the Mobile based on input parameters processed by the Server by
pre-programmed logic based on
latitude, longitude, compass direction, distance between mobile and device
The Device is the output sensor in the system.
The Device can be an audio/video output device or input device
B. 4. LNS Action
The Action is measured in seconds and is the information provided on the
Device if the Mobile is near and the Mobile has approved that about the
Mobile
latitude, longitude, compass direction
B. 5. LNS Agency
The agency is the programmed system operators that returns output sensors
to the device based on input sensor parameters from the mobile
B. 6. LNS Ask
B. 7. LNS Bid
B. 8. LNS Match
