The present invention relates to a call processing method of a mobile communication system, and more particularly, after finishing a call in a mobile communication system, various information and messages stored in advance by a caller can be transmitted to a receiving terminal to leave the afterglow of a call. The present invention relates to a call processing method of a mobile communication system that enhances the effect of an advertisement and facilitates the convenience of a caller.

Today, mobile communication terminals are becoming a necessity of life due to the simplicity and convenience of portable, and are used by many people. Such mobile communication terminals have been changed into a means for personal information management function beyond the means for phone call because of the phone book registration, schedule management function.

In addition, the remarkable development of computer-related information and communication fields not only drastically improves work efficiency, but also greatly changes our daily lifestyles.

For example, in the form of shopping related to product purchase, the use of product purchase using an online shopping mall on a computer is gradually expanding.

In addition, the system and method for receiving a variety of information in real time by accessing a network such as the Internet through a mobile communication terminal are actively being searched for, and an image transmission movement such as IMT 2000 (International Mobile Telecommunication for the 2000s) As communication terminals have been developed, many researches have been conducted on service systems and methods using them.

As such, recently, a next generation mobile communication network capable of providing high quality communication services and various additional services according to the development of communication technology, that is, a next generation mobile communication network collectively referred to as IMT 2000 or Future Public Land Mobile Telecommunication System (FPLMTS) is commercialized. It is expected to be. The next-generation communication network adopts a data packet transmission method to transmit and receive voice, video, or data files at high speed, and also, in order to secure a high data rate, for example, 1,855 MHz to A frequency band of 2,111 MHz or 2,110 MHz to 2,200 MHz is used. And such next-generation mobile communication networks can build the whole world in a single call zone.

On the other hand, if any caller transmits a call signal for calling the mobile communication terminal to the mobile communication system, the mobile communication system determines whether the corresponding mobile communication terminal received the call signal. At this time, the mobile communication system transmits a busy signal and a call signal to an arbitrary user and forms a call with the mobile communication terminal when the call is possible, depending on whether the mobile communication terminal can be called.

1 is a schematic diagram of a mobile communication network for explaining a general call processing state.

As shown here, the calling terminal 10 is connected to a Mobile Switching Center (MSC) 20 through a base station (not shown) and the calling terminal 10 is connected to the calling switch 20. An originating Home Location Register (HLR) 30 for registering the location and status of the is connected. In addition, the receiving terminal 60 is connected to the receiving side exchange 40 through a base station (not shown) and the receiving side home for registering the position and state of the receiving terminal 60 in the receiving side exchange 40. The location register 50 is connected. The source exchanger 20 and the receiver side exchange 40 are connected to each other via a mobile land network (PLMN) 70.

In the call processing process of the mobile communication system, a call setup request is made from the calling terminal 10 to the calling exchange 20 in order to make a telephone call from the calling terminal 10 to the calling terminal 60 as shown in FIG. (S10). Then, the originating exchange 20 registers the position of the originating terminal 10 with the originating home location register 30 and attempts to connect the call to the receiving exchange 40. At this time, the receiving side switch 40 determines the position and state of the receiving terminal 60 from the receiving home position register 50, and then requests a call setup response from the receiving terminal 60 (S20).

Thus, when the receiving terminal 60 responds to this, a call connection is made between the calling terminal 10 and the receiving terminal 60 (S30), and a telephone line is formed by forming a call path until the telephone call ends. It is possible to (S40) (S50).

However, if the receiving terminal 60 does not respond to a call setup request with a busy or no answer (S20), the busy terminal signal or ring tone indicates that the receiving terminal 20 does not answer the calling terminal 10. After sending the notification and the user guide message for the use of the "soriille" or "voice mailbox" is sent (S60).

Then, when the user records the telephone number or message to be contacted according to the user guide message, the user transmits the input contents to the receiving terminal 60 to notify that the call has been made (S80).

Nowadays, while requesting call setup in the general call processing as described above, instead of the ring tone, randomly set music or messages are sent to facilitate the user's convenience.

In addition, a call processing method for enhancing an advertisement effect, such as discounting a call charge, is provided when listening to an advertisement before call setup.

However, after the call is terminated, there is no method of providing a greeting or a message or advertisement preset by the caller, which may leave the afterglow of the call.

The present invention was created to solve the above requirements, and an object of the present invention is to leave the afterglow of a call by transmitting various information and messages stored in advance by a caller to a receiving terminal after a call is terminated in a mobile communication system. In addition, the present invention provides a call processing method of a mobile communication system that can enhance the effect of advertisement and facilitate the convenience of the caller.

According to an aspect of the present invention, there is provided a method of storing a message in a service server according to a subscription of a message transmission service in a mobile communication system, and after a call is connected between a caller's calling terminal and a called party's receiving terminal. Determining whether the connection call has ended, and if the call is terminated, determining whether the calling terminal has subscribed to the message transmission service and reading a message stored in the service server only if the subscriber is a subscriber; The read message is transmitted to the receiving terminal by a short message service or a multimedia messaging service.

In the present invention made as described above, when the call is terminated after making a phone call in a call connection state, the caller receives a message stored in advance from the service server and receives a greeting, text message, advertisement through a short message service or a multimedia messaging service. Etc., it is possible to leave the afterglow of the call or increase the effectiveness of the advertisement.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only and the same parts as in the conventional configuration using the same reference numerals and names.

3 is a block diagram showing a mobile communication system to which the call processing method of the mobile communication system according to the present invention is applied.

As shown here, the calling terminal 10 is connected to a Mobile Switching Center (MSC) 20 through a base station (not shown) and the calling terminal 10 is connected to the calling switch 20. An originating Home Location Register (HLR) 30 for registering the location and status of the is connected. In addition, the receiving terminal 60 is connected to the receiving side exchange 40 through a base station (not shown) and the receiving side home for registering the position and state of the receiving terminal 60 in the receiving side exchange 40. The location register 50 is connected. The source exchanger 20 and the receiver side exchange 40 are connected to each other via a mobile land network (PLMN) 70. In addition, a service server 80 for storing a message designated by the caller for the call after service and providing the same to the receiver is connected to the calling exchange 20 and the receiving exchange 40 through the Internet 110. The sending side short message transfer server 90 is connected to the calling side exchange 20, and the receiving side short message sending server 100 is connected to the receiving side exchange 40.

4 is a flowchart illustrating a call processing method of a mobile communication system according to the present invention.

First, when a call is made in a state in which a call connection is made between a calling party's calling party terminal 10 and a called party's receiving party terminal 60 by a general call processing method (S100), the connection is terminated. The end of the call is determined (S110).

When the call end is determined as described above, a message stored in advance for transmission to the receiver from the service server 80 is read (140).

At this time, before the message is read from the service server 80, the caller reads the message only if the caller determines whether the service is subscribed (S120) and the message is read. The call ends (S160).

In this case, the caller who subscribes to the call forwarding service reads a message from the service server 80 and transmits a short message service (SMS) or a multimedia messaging service (MMS) to the receiving terminal 60. Through the transmission (S150).

At this time, a specific message can be transmitted to a specific receiver. In this case, the receiver determines the designated recipient through the telephone number of the receiver (S130) and then reads the specified message from the service server 80 (S140). It is transmitted to (S150).

In this case, the transmitted message may be provided in various forms such as a personally written text message, a business card, a picture, a picture, or a music, but may be selectively provided according to the type of the receiving terminal 60.

Therefore, when the text message is transmitted by the short message service, the short message may be immediately displayed on the receiving terminal 60 to have a call finish. However, in the case of a multimedia message such as a photo or music by the multimedia message service, the receiving terminal receives a call suffix by accessing the service server 80 from the receiving terminal and confirming the multimedia message transmitted to itself.

On the other hand, when reading the message stored in the service server 80, the type of the receiving terminal 60 is determined, and if the corresponding receiving terminal 60 is unable to process the message stored in the service server 80 is unprocessable You can also send only announcements.

As described above, the present invention transmits various information and messages stored in advance by the caller to the receiving terminal after the call is terminated in the mobile communication system. There is an advantage to this.
