This document outlines the specifications for a mobile game application called "CONNECT 4" that allows two players to play against each other via a central server. It describes the development platform as J2ME, and discusses features such as OTA updates, WAP push notifications, and supporting a variety of device types through the use of socket connections and the WURFL framework. The application follows an MVC architecture with separate classes handling the model, view, and control layers.

Internet
Server Side Server

7.  Socket connection
 Send and receive data
 Dynamic domain name
(Server could be anywhere)

8.  Responsible for logic and algorithm
 Invoke View layer and Network layer
 Composition a chess class which stores
all data of chess

9.  Responsible for displaying everything in
Canvas
 If something should be displayed on
screen, invoke repaint()

11.  Flash lite: already saw
 OTA, Wap push: new version notification
 Demonstration: game
 Run seamlessly on a variety of devices
• Socket connetion
 WURFL

12.  Flash lite
› already saw
› Version 1.1

13.  Can be download Over the air
 WAP push functionality
› Each time launch the game, if there is a new
version, the server will notify the user

14.  WAP push
 server only accept 2 users
 exit now? Both disconnect
 playing
 exceed 30s? Automatically…
 win
 continue show…
 one exit, both disconnect

15.  Run seamlessly on a variety of devices
› We use socket connection to server
› SO devices must support MIDP 2.0
› Some Sony Ericsson devices not support
socket connection

16.  WURFL
› PC
› Mobile device
