mobile contact backup

A java/midp system that provides a way for users with internet enabled phones(gprs/3g/wifi) to upload phone contacts (numbers + names )held in their phone memory and sim card to a server. These details can later be retrieved in the event that the user looses the ones on their phone.

These details are saved onto a mysql database where every user has a table(tablename is their phone number) that contains as columns; contact_name | contact_number , for every contact they have.

This will be a pay service ,so create a table that holds the system user's phone number ,pin code and a pay status;( user_number |pin_code | pay_status).This table should be editable from the database console, By a system administrator.

When the system user/client attempts to backup the contacts on their phones, they enetr their phone number. The server program( java) then checks the main table to acertain that their pay_status is valid. If it is, the backup should carry out successfully. Otherwise they are encouraged to make payment through the advertised mode.

The client side midp application should provide the following features;

a)backup contacts.

-user enters their phone number and pin.

-from the listed contacts(choice menu),the user then chooses ALL contacts, or some.

-then the midlet collects contacts on phone+sim memory, which are sent to the server via httpconnection or socketconnetction .

b)download contacts

-the user enters their number and pin and after confirmation from the server, all their saved contacts are downloaded and restored into their phones.

the server side;( java and mysql)


-first confirm that the user number and pin are valid, then if pay status is [url removed, login to view] all valid..

-incoming contacts are saved onto the database.


-first confirm that the user number and pin are valid, then if pay status is [url removed, login to view] all valid..

-saved contacts are downloaded into their phones where the client side midp takes over.

Should work on both Java and Symbian OS's
