Abstract

PURPOSE: A method for switching a character message to an external server in a wireless communication system is provided to replace a conventional ARS(Automatic Response System) by connecting a character service of a mobile communication system to the external server. CONSTITUTION: In case that an MSC(Mobile Switching Center) receives message transmission request, the MSC judges whether a "14..." number is included in a callee number of the message(S1). In case that the "14..." number is included in the callee number of the message, the MSC requests an SMSC(Short Message Service Center) that the message is provided to an external server(S2). In case that the message transmission is requested from the MSC to the external server, the SMSC confirms a corresponding server on the basis of a next number of the "14" and requests an SMAP(Short Message Application Part) that the message is provided to the corresponding server. The SMAP converts the message into a format requested from the corresponding server(S3), and the formatted message to the corresponding server through a PSTN(Public Switched Telephone Network) or an Internet network(S4).

Description

Method of transfering a character message of a wireless communication system to an external server}

The present invention relates to a wireless communication service method. In particular, the present invention relates to a method for converting a text message in a wireless communication system to an external server.

Various service organizations are using the ARS for public opinions of users, for example, ranking of show entertainment programs of general broadcasting stations, participating viewers, or receiving application songs. However, such ARS has a problem that a high probability of a call failure occurs when the call is congested with a limited amount of calls. Also, the ARS is not attracting more participants at that high rate. Therefore, there is a demand for a new service method that can replace such ARS.

Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method for converting a text message of a wireless communication system that can replace a conventional ARS service to an external server.

A method for converting a text message of a wireless communication system to an external server according to the present invention for realizing the above object comprises: a) assigning an identifier number to each of at least one or more external servers; b) when receiving a call request from a mobile station to a predetermined identifier number, providing a message to the mobile station from an external server corresponding to the identifier number; c) providing a message from the mobile station to the external server according to the message provided to the mobile station.

According to the present invention, by connecting the text service of the mobile communication system to an external server, it is possible to replace the existing ARS system.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a diagram illustrating a wireless communication service system to which the present invention is applied.

Referring to FIG. 1, a wireless communication service system to which the present invention is applied includes a base station 120, an MSC 125, an HLR 160, a short message service center (SMSC) 190, and a short message application part (SMAP) 210. ).

The base station 120 includes a transmission equipment, a BTS 121, and a BSC 123 necessary for network connection. These may be formed together in the same place or may be installed and operated in separate places. However, in the present invention, since there is no need to distinguish them, they are grouped together to be referred to as the base station 120.

The HLR 160 stores information about allocated subscriber mobile terminals 170, including location information and service information, in its database (not shown).

The SMSC 190 provides a text service to a subscriber and generates various messages according to a request signal from the MSC 125. The SMSC 190 also provides a message from the external server 220 to the mobile station, and provides a message from the mobile station 170 to the server 220 to the server 220.

The Mobile Switching Center (MSC) 125 interfaces user calls from a wireless network to a wired network or other wireless networks. The MSC 125 may be connected to a plurality of base stations. The MSC 125 according to the present invention requests the SMSC 190 to provide a message from the mobile station 170 to the server 220 upon receiving a message delivery request to the server 220.

The MSC 125 identifies the server 220 to which the message should be transmitted based on the message request number. For example, as shown in Table 1 below, a specific ID is assigned to each external server to determine a server to receive a message.

division MBC KBS radio SBS DA 14 ×× 14 ×× 14 ×× 14 ×× Client_Name MBCMEMO KMSMEMO RadioMEMO SBSMEMO

Table 1. Server Identification Information

That is, when the MSC 125 includes the DA "14" in the called party number from the outside, the MSC 125 determines that the called party is one of the external servers, and provides the server belonging to the called party number to the corresponding server. Request to SMSC 190.

The SMAP 210 provides an interface between the SMSC 190 and external servers 220. The SMAP 210 converts the message data from the SMSC 190 and provides it to the server 220 through a network connected to the servers 220, for example, a PSTN or an internet network.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

FIG. 2 is a flowchart illustrating a method of converting a text message to an external server in the wireless communication system of the wireless communication service system shown in FIG. 1.

When the MSC 125 receives the message delivery request, the MSC 125 determines whether the called party number of the message includes "14 ..." (S1).

If the called party number of the message includes "14", the MSC 125 determines that the called party of the message is external servers 220, and transmits the message to the SMSC 190 to an external server. 220 to request to provide (S2).

When receiving a message transfer request from the MSC 125 to the external server 220, the SMSC 190 based on the number " ×× " after the " 14 " ), And requests the SMAP 210 to provide the message to the server 220. Then, the SMAP 210 converts the message into a format required by the corresponding server 220 and provides the formatted message to the corresponding server 220 through a PSTN or an internet network.

Therefore, according to the above configuration, it is possible to provide text messages of mobile communication to external servers.

As described above, according to the present invention, a method of converting a text message of a wireless communication system that can replace a conventional ARS service to an external server can be realized.

Although the present invention has been described in detail by the above embodiments, the present invention is not limited thereto, and variations and improvements can be made without departing from the ordinary knowledge of those skilled in the art.

Claims (1)

a) assigning an identifier number to each of at least one or more external servers; b) when receiving a call request from a mobile station to a predetermined identifier number, providing a message to the mobile station from an external server corresponding to the identifier number; and c) providing a message from the mobile station to the external server in accordance with the message provided to the mobile station.
