First, in a mobile communication network, a customer inputs a representative number (eg, 1588-****) using his or her calling terminal 10 to use a calling service such as a call taxi service, a courier service, or a quick service. As a result, a call connection is attempted with respect to the calling mobile switch 20 to which the calling terminal 10 belongs (step 201).

Then, the calling party mobile switch 20 uses the representative number inputted by the customer to the calling terminal 10 and the location information of the calling terminal 10 managed by the calling party mobile switch 20. A call establishment request message (IAM) is transmitted to the call service providing server 30 requesting call establishment (step 202). In the present invention, the location information of the caller, that is, the customer, is automatically transmitted to the call service providing server 30 when the call is originated, so that the location of the caller can be easily determined.

Subsequently, the call service providing server 30 provides the customer with a guide broadcast regarding a type of a call service or a grade of a service to be provided according to the representative number input by the customer. Then, the customer can select the type of service desired and the level of the service to be provided according to the announcement. For example, when a customer enters a representative number for the integrated calling service, the customer may select which service to use among call taxi, surrogate driving, or quick service. In addition, when the customer selects the call taxi service, the service class is selected again. As an example of selecting a class of service, a number 1 may be input by using a keypad of the mobile terminal 10, a number 2 may be a model taxi, and number 3 may be selected to select a large taxi. . If the customer enters the representative number for the call taxi service, the announcement may be sent out so that the user can select the class of the service immediately (step 203).
