1 is a block diagram of a private mobile switch implemented to enable a private mobile communication service to which an embodiment of the present invention is applied. Referring to FIG. 1, the private mobile switching unit 106 may include a web server 108, a VLR (Visitor Location Register) 110, and a short message service center (SMSC) to implement a private mobile communication service. 112, a mobile switching center (MSC) 114, a base station controller (BSC) 116, a base station transceiver subsystem (BTS) 118, and the like.

Web server 108 provides SMS access and service of SMS user in private mobile switch 106, and acts as CGI program therein to inform SMS user of short message transmission result. The SMSC 112 receives the short message transmission request from the web server 108 and sends it to the MSC 114, and also receives the short message transmission result from the MSC 114 and notifies the web server 108 of the result. . The MSC 114 performs overall call processing for general campus radio calls and SMS messages. The BSC 116 controls the BTS 118 and serves as an interface between the MSC 114 and the on-premises wireless terminals. BTS 118 provides premises terminals 120 and the air interface of the private mobile switching period. The web browser 100 is connected to the web server 108 and the TCP / IP network 104 and transmits a short message input from an SMS user through a web screen to the web server 108.

The SMSC 122, the MSC 124, and the BSC 126 outside the private mobile exchange exchange the short-term BTS 118 of the private mobile exchange 106 as a part of providing a short message and a general call service in a conventional general public network. To perform the short message and general call service.

2 is a flowchart illustrating a process for identifying a source when transmitting a short message from a private mobile switching center to a wireless terminal in a premises according to an exemplary embodiment of the present invention.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when a user wants to transmit a short message to a subscriber of a wireless terminal in the registered mobile switching center using a PC connected to the private mobile switching center, the user drives a web browser for SMS short message service to the PC connected to the private mobile switching center. After writing the desired short message, the registered premises telephone number of the subscriber of the premises wireless terminal to be transmitted is input. Then, the web browser 100 running on the user's PC transmits the short-term message to the web server 108 of the private mobile switching unit 106 and the short-term message of the corresponding wireless terminal. Then, the web server 108 in the private mobile switching unit 106 receives the short message transmission request transmitted from the web browser 100 of the user PC in step 200 of FIG. Proceed to step and transmit the received short message to SMSC 112.

In step 204, the SMSC 112 examines the VLR information of the corresponding wireless terminal 120 to check whether the short message can be transmitted to the wireless terminal 120. In this case, if the campus wireless terminal 120 is unable to receive the short message, the SMSC 112 proceeds to step 212 to inform the web server 108 that the short message cannot be transmitted. . When the campus wireless terminal 120 is unable to receive the short message, for example, when the subscriber to the campus wireless terminal is out of the private mobile switching service area or the subscriber has turned off the campus wireless terminal power This can be a variety of situations.

On the contrary, when the VLR test result of the premises wireless terminal 120 in step (204) is the situation that the corresponding wireless terminal 120 can receive the short message, the SMSC proceeds to step (206) and the transmission In the header part of the short message, source identification information indicating the transmission in the premises is inserted. In step 208, the SMSC 112 transmits the short message to which the source identification information is added to the header, to the MSC 114.

Accordingly, the MSC 114 controls the BSC 116 to wirelessly transmit the short message to the corresponding local wireless terminal 120 through the base station (BTS) 116 and receives the short message. The subscriber can view the source identification information included in the short message so that the short message can be easily known whether the short message is originated from an external public network or from an internal (premises) private network.

In step 210, the SMSC 112 receives the short message transmission result message transmitted from the MSC 114 after performing the short message transmission, and proceeds to step 212 to transmit the short message transmission result to the web. The server 108 transmits the data to the web browser 100 of the user PC. Accordingly, the calling user can check whether the short message sent by the user through the web browser 100 screen is transmitted.

As described above, according to the present invention, when a short message is transmitted from a private mobile switching center to an on-premises wireless terminal, a sender ID information is inserted into the short message and transmitted to the receiving party. There is an advantage to know.
