Even if they advertise according to the consumer's consent, they have to take time to listen to the ads in return for returning the cost of the advertisement. There was an inconvenience of not having realized the target advertisement, which is the strength of mobile phone advertisement, by having advertisements without considering the characteristics of each user.

In mobile phone call waiting (CRBT), this is a service that allows the caller to listen to the music subscribed and stored by the caller during the call waiting time until the caller attempts the call and the call with the called party is connected. This method allows the caller to listen only to the music stored by the called party in the database on the server, which requires frequent exchanges due to repetitive boredom. And simply by providing only the sound source has a limit in providing a variety of information from time to time.

 The technical problem to be achieved by the present invention is to solve the above problems by advertising the mobile phone call waiting sound without spending a specific time to the consumer, subscribers play a role of advertising media by serving as an advertising medium Advertisers can reduce the risk of advertisement by selectively advertising advertisements that are directly related to each consumer.

It is to provide a method for more convenient and effective advertising by minimizing the rejection of consumers to the call waiting sound portion coming out.

In order to achieve the object of the present invention as described above, the present invention provides a method for advertising and money transfer service using a mobile phone call waiting sound advertising to the caller using a mobile communication network,

(1) performing a user registration by receiving a subscription request for an advertisement and a money refund service using the mobile phone from a mobile communication subscriber (m);

(2) any caller M 'attempts to make a call with any mobile subscriber m;

(3) The base station detects and transmits the signal of the caller (M ') and retrieves the subscriber information (HLR, VLR) from the mobile switching center (T) to determine if any mobile subscriber (m) is the subscriber (M) of the service. Determining whether or not;

(4) reading the advertisement code stored in the subscriber area 101 on the database D through the CP server C when the called party m is the subscriber M of the service;

(5) The advertisement stored in the registered advertisement data area 202 on the database D is transmitted to the caller M 'through the mobile phone speaker of the caller M' by the advertisement code stored in the subscriber area 101. Making a commercial;

Meanwhile, incoming and outgoing terminals using mobile subscribers according to an embodiment of the present invention include a PDA, a cellular phone, a PCS phone, a GSM phone, a W-CDMA phone and a CDMA-2000 phone.

The mobile communication system refers to a system built by existing mobile communication providers such as a radio access network (RAN), a mobile switching center (T), and subscriber information (HLR, VLR).

The radio access network (RAN) serves to guarantee the mobility of the mobile communication terminal, and performs handoff and radio support management functions. The radio access network includes a transmission tower and a base station controller, and supports both synchronous and asynchronous.

The transmission tower receives the call request signal from the mobile communication terminal and transmits the received call request signal to the base station controller.

The base station controller controls the transmission tower, and performs radio channel assignment and release to the mobile communication terminal, transmission output control of the mobile communication terminal and the transmission tower, and the like. The base station controller transmits the call request signal received through the transmission tower to the mobile switching center (T).

The mobile switching center (T) performs basic and additional service processing, incoming and outgoing signal processing of the mobile subscriber (m), location registration procedure and handoff procedure processing, interworking with other networks, and the like.

In the subscriber information (HLR, VLR), the Home Location Register (HLR) receives the location information of the terminal from the VLR (Visitor Location Register) and performs functions such as registration recognition, registration deletion, and location verification. In addition, the HLR stores information on subscribed mobile communication services of the incoming and outgoing terminals (for example, whether to subscribe to advertisements and money exchange services using a mobile phone).
