3 is a flowchart illustrating a function commonly performed by an SMS supplementary service device (ESME) 107 according to the present invention. SMS supplementary service is delivered through short message reception and processing by linkage with SMC, BCCS-IF and external network (Hitel, E-mail, Web). Although the service processing procedure varies depending on the type of SMS supplementary service, processing method, and characteristics of the network to which it is connected, the basic processing method is the same. Therefore, the flowchart of the service processing performed by the SMS supplementary service device (ESME) in common makes it possible to easily perform additional service development. The supplementary service according to the present invention processes a service by requesting a subscriber from SMC, requests delivery of a notification message from BCCS-IF, and connects a virtual connection to receive and deliver a short message from an external network. Parts and service processing parts vary depending on the nature of the service, but the basic procedures for processing other services apply jointly.

The overall step consists of receiving a message and sending a message.

In FIG. 3, 3100, 3200, and 3300 are steps of configuring an environment for driving each SMS supplementary service. ESME program to provide each SMS supplementary service receives supplementary service processing request from SMC, BCCS-IF and external network, and receives unique PCS number which is its service identification number as a parameter during invoke. It registers as a parameter in the VAS 106 as a parameter and checks whether the address of the ESME is input (3100). Two processes for transmission and reception create a transmission / reception pipe for delivering a message (3200). When the pipe is normally created, the process is forked, driven independently and starts to exchange messages with the short message processing system (SMC) 105 (3300).

Steps 3400 through 3406 are processes of a message receiving process, which receive an additional service processing request message from the SMC, BCCS-IF and the external network, transmit a response thereto, and transmit the received message for service processing. It performs the function of passing to the process. After the message receiving device 201 is bound to the short message processing system (SMC) 105 to receive a message from the SMC, BCCS-IF and the external network, a virtual connection is established (3401). Waits for receiving a subscriber message from short message processing system (SMC) 105 (3402). It is checked whether the subscriber message has been input (3403), and if received, it is received from the short message processing system (SMC), BCCS, and the external network (3404) to receive the message with the short message processing system (SMC) 105 and BCCS. It sends 3405 and then forwards the subscriber message to the sending process (3406). If no input is made, the process returns to step 3402 and continues to wait for a message.

Steps 3500 to 3510 are processes of a message transmission process, and after receiving a service processing message from a receiving process and performing message processing according to an additional service characteristic, the service processing result is bound by SMC and external network. Performs a function of creating a history of the processing result for each service process after the transfer. The message transmission device 202 is bound to the short message processing system (SMC) 105 via SMPP, establishes a virtual connection (3501), connects to the database system (3502), and requires an administrator for service registration information. After reading the management parameters from the management table in the SMS supplementary service device (ESME) (3503), the subscriber message recorded in the message storing step (3406) of the message receiving process is received through the pipe set in the pipe creating step (3200). (3504) Perform a message processing function (3506). In this case, the procedure of the message processing function may vary according to the type or characteristic of the additional service. Types of services include PCS subscriber information retrieval service, billing information service, reservation time notice service, anniversary notice service, securities information service, message publication service, service number guide service, web page interlocking service, and Internet e-mail service. It also includes information service system hit (Hitel) services. In the message processing step 3506, the result of processing each additional service is transmitted to the short message processing system (SMC) 105 (3507), and the service can be delayed or controlled by the administrator's control in consideration of the internal system load. The traffic is processed according to the number of occurrences (3508). Subsequently, log data is created for each request number (3509) and a log file is generated (3510). The generated result can be used to generate various statistics such as service history and time zone, or can be used as system management data.
