This document discusses location-based reminder applications and proposes an architecture for location-based services using GPS. It describes how location-based reminders can remind users to do something when arriving at or leaving specific locations. It then proposes a system architecture divided into five components: task management, user interface, trigger management, service management, and storage/retrieval management. Finally, it discusses technologies involved like GPS, location-based services, and considerations for implementation.

Although location-based reminder applications have been
widely prototyped, there are few results regarding their
impact on people: how are they used, do they change
people’s behavior and what features influence usefulness the
most.
Cell phones provide a compelling platform for the delivery of
location-based reminders within a user's everyday natural
context.
In this paper we propose an architecture of location based
services which uses GPS.

3. 


Location-based reminders that remind you to do something
when you arrive at, or leave, a specific location such as your
office, your home, or any other address in your Contacts list.
The main purpose of location-based services is to provide
services to customers based on the knowledge of their
locations.
Cell phones now emulate computers, with enhanced graphical
user interfaces, integrated Global Positioning Systems,
wireless data connectivity, efficient batteries, powerful central
processing units (CPU), and expanded storage capabilities.

Case 1: Forget bought fresh strawberry after your weekly
shopping?
Forget,
No Problem. Location Based Reminder will remind you.
Case 2 : There are several colors you can choose for your
reminder. You can also set a radius of a circle in which you
will be reminded.
Case 3 : Snooze is another interesting function. You will be
snoozed after preset time duration and only if you are still in
the reminder area.

5. 

The main idea of the architecture is to embed various
information in service trigger mechanism and service itself.
For example, dynamic route guidance service.
In reminder services, the service needs to decide whether or
not to post the message to user according to user’s location,
incident property.

6. It can be divided into five parts which are:
1)
Task management component
2)
User interface component
3)
Trigger management component
4)
Service management component and
5)
Storage and Retrieval management component.

8. A. GPS and Google Maps



Connecting GPS receiver to PC and PDA.
GPS receivers are now embedded into mobile
phones and applications using the location of the
user in real-time are widely available.
GPS chips are now included in many devices to
analyze satellite signals and determine the user’s
location with high accuracy.

9. B. Location Based Services:
 Location Based Service (LBS) LBS is mobile service that has the
capability to provide real time information based on the user’s
location.
 Geographical Information System (GIS) has been the heart of LBS in
order to provide all the functionalities in LBS.
1. we may send location information to remote parties.
2. Second, use location information to make communication
decisions.
3. Third, location changes can trigger communication actions.
 e.g., when a person’s user agent gets a location notification
indicating the person enters a room, the user agent may
automatically turn on the light of the room.

10. c. Reminders as Per Situation
 Different locations may require different communication
behaviors.
 For example, video or text conversation is not good when
driving.

Proposal of an integrated android application based on
location information.
(1) Creating and editing event content,
(2) System to upload location information,
(3) Search function using location information of the user,
and
(4) Displaying search results on the screen.

13. The proposed web server will consist of
the following:
• User module to create and store contents,
• Search module to search the content database,
• Response module to respond to requests from the client for web
contents.

15. 


When the user requests date to create content, the request is
received by the builder module, and handed to the data
module.
The data module first searches the RMS (Record Management
System) provided by J2ME to see if stored in the cache.
When no corresponding information is found, the data
module obtains the necessary information from the web
server by using HTTP transfer.

17. 

XML content sent from the client is distinguished by the
subscriber ID, which is attached to the HTTP request header.
It is then translated into WML and stored in the database to
support WAP browsers.

18. 1)Android SDK / Java:
•
Android is an open source operating system for mobile
devices developed by Google.
•
One of the key features of Android is its ability to extend
the functionality of devices through new applications (or
apps).
•
The Android SDK is a collection of APIs and tools that
facilitate Android application development.

19. MySQL:
MySQL is an open-source database management system that is
licensed for free under the terms of the GNU General Public License.
Because of its open license, MySQL is one of the most popular
database management systems for both commercial and personal use.
Data is inserted and modified using commands sent to the
database in Structure Query Language (SQL) syntax. File.
Apache Web Server:
Apache is free software, distributed by the Apache Software
Foundation that promotes various free and open source advanced Web
technologies.

GPS on cell phones is a bit more murky.
In general, it won't cost you anything to turn on the GPS in your cell
phone.
But when you get a location it usually involves the cell phone
company in order to get it quickly with little signal, as well as get a
location when the satellites aren't visible.
It uses up some cellular bandwidth.

C# is a multi-paradigm programming language
encompassing strong typing, imperative, declarative,
functional, generic, object-oriented (class-based), and
component-oriented programming disciplines.

This paper focuses on communication related location-based
services, GPS and system Architecture.
In Internet telephony systems.
Restaurant queries.
Traditional restaurant queries only consider the distance,
while we aim to change to provide better results by
considering not only distance but also user preferences.
Environmental context.
