A system and service method for processing at the same time.

For reference, SMS refers to a service that enables data communication in a wireless network by serving as a bridge between a wireless network and data contents outside the wireless network by using an SS7 network protocol connecting a wired or wireless network. Although SMS is connectionless rather than connection-oriented, it is not easy to use the wired Internet that is currently used. However, SMS is a method of enabling data communication in a circuit-based wireless network. Introduction and easy data transfer methods have been a huge success worldwide.

Currently used SMS service network can be classified as shown in Figures 4 and 5 attached.

Figure 4 shows the configuration of a WAP PUSH network of conventional wireless communication.

In such a configuration, various types of information on the Internet 421 and 431 are managed and stored on the Internet using a push proxy gateway 420 or a WAP gateway 430, and the terminal processes the information when the user 400 requests information. By converting the information into an appropriate form so that the information can be quickly transmitted to the terminal through the transmission antenna or the base station 410 to provide an SMS service using the Internet and wireless communication.

However, this method must be directly contracted with a mobile carrier to be applied to all mobile phones that are serviced in Korea, and it is not widely used due to the large cost burden of using the SMS transmission line.
