Abstract: For solving communication hazards generated by lacking objects of products while technical problems of the products are discussed between customer service providers and customers, or between customer service providers and technical support providers, and for saving room for depositing the objects of various products, an application program, which includes a plurality of user interface simulation programs corresponding to a plurality of products, is provided for the customer service providers. With the aid of the provided application program, when the customer service providers communicate technical problems of products of various types with others, a corresponding user interface simulation program is called for simulating solutions provided by the technical support providers, or for providing the solutions for the customers in detail.

Abstract: A mobile communication system is disclosed. The mobile communication system includes a first communication module, wherein the first communication module includes a first global positioning device utilized for determining a coordinate of the first communication module; a first communication apparatus, coupled to the first global positioning device, for receiving a coordinate of a second communication module; a first operating interface; and a first processing circuit, coupled to the first communication apparatus and the first operating interface, for controlling the first operating interface to indicate a position of the first communication module according to the coordinate of the first communication module or controlling the first operating interface to indicate a position of the second communication module according to the coordinate of the second communication module.
