Google Inc. is planning a new search service for mobile users that will help them find and buy mobile content, such as ringtones and games, the Wall Street Journal has reported.

While Google has had the services for mobile users to search the Web, the search engine would like to become a portal for finding and purchasing mobile media content.

The company has been working with mobile phone content providers for several months to index their products and make them available on the mobile search. However, the plan has been delayed due to a series of technical issues, and the launch date for the service is not yet clear, according to people familiar with the matter, the Wall Street Journal stated.
