Abstract: A method for setting a number of advertisements desired to be received from an advertisement server when a user requests an advertising service. In particular, if the user sets the desired number of advertisements through an advertisement application, the advertisement application provides an advertisement engine with an advertisement request including the set number of advertisements. An advertisement engine determines if the number of advertisements stored in a memory of the terminal is greater than or equal to the requested number of advertisements. If the number of advertisements stored in the memory of the terminal is less than the requested number of advertisements, the advertisement engine makes a request for advertisements to an advertisement server and receives the advertisements. Therefore, the advertisement application can receive the requested number of advertisements from the advertisement engine, so that it is possible to provide the user with a more differentiated MobAd service.

Abstract: A method for a user to receive an advertisement directly reflecting the user's liking. When a client registers event information set by a user into a server, the server provides a corresponding advertisement by retrieving if there exist advertisements corresponding to the event information registered into that server. Also, the client registers both event information and preference information into the server considering the liking of the user. By doing this, the user can receive an advertisement directly reflecting his liking. Also, the user information can be protected by only outputting the information into a mobile terminal.
