The present invention relates to a short message reception processing method of an all-electronic exchange, and more particularly, to a short message reception processing method of an IS-637 protocol structure applied between a personal communication exchange and a short- To a TDX-10 PCX full-time electronic exchange.

In this regard, the short message service, which is one of the additional services of mobile communication and personal communication services, is commercially available in Europe and the like. In order to export mobile communication and personal communication exchanges from the standpoint of us, It is necessary to improve various functions.

Accordingly, the short message service call forwarding function according to the IS-637 protocol structure is implemented in the TDX-10 PCX electronic exchange.

An object of the present invention is to provide a TDX-10 PCX capable of implementing an incoming call processing function of a short message service function in a dormant state of a terminal, a terminal in a handset state, And a method for processing an incoming short message.

The above and other objects and advantages of the present invention will become more apparent from the following description of the preferred embodiments of the present invention with reference to the accompanying drawings, by persons skilled in the art.

Hereinafter, embodiments of the present invention for achieving the above-described objects will be described in detail.

FIG. 1 is a block diagram illustrating a method for processing a short message according to an embodiment of the present invention. Referring to FIG. 1, there is shown a TDX-10 PCX electronic switching system 10, (TDX-10 PCX electronic switching center) 30 such that the first electronic switching center 10 performs the exchange function of the corresponding subscriber and the second electronic switching center 30 also exchanges the corresponding subscriber And the first and second electronic switching units 10 and 30 may communicate with each other through a predetermined communication line.

Hereinafter, the present invention will be described with reference to FIG.

FIG. 2 is a flowchart showing a step-by-step message reception processing method of an all-electronic exchanger according to an embodiment of the present invention.

That is, in the idle state of the corresponding terminal (not shown in the figure), the busy state of the terminal, or the handoff state of the corresponding terminal, the corresponding base station controller (not shown in the figure) Then, the procedure of the short message receiving procedure to be transmitted from the first electronic switching center 10 to the second electronic switching center 30 is as follows.

First, the short message arrival signal transmitted to the LRSC block 12, which is the mobility management Map matching control block in the first electric switching center 10, is transmitted to the LCC (14) block, which is a visitor location register (VLR) The LCC (14) block transforms it into an internal signal form and transmits it to the short message control (SMCO) block (16) block (002).

Then, the SMCO 16 block checks the status of the terminating terminal through the information received from the LCC 14 block and sends a short message to the PCS interface block 18, which is a PCS matching block, The PCSI 18 block transmits a short message reception signal to the corresponding base station controller (004), starts a corresponding timer, and waits for a reception response (005).

In order to check the status of the receiving terminal in the above-described step (003), if the receiving terminal is in the communication state, the PCC call control block 20, which is a mobile call control block, (104). If the destination terminal is not in the handoff, the short message reception signal is transmitted to the corresponding PCSI (18) process ID through the information received from the PCC (20) block (105).

Thereafter, the PCSI block 18 sends a short message arrival signal to the corresponding base station controller (106), starts a timer and waits for a reception response (107).

In order to confirm the state of the receiving terminal in step (003), a request is made to the PCC (20) block, which is a mobile call control block, to confirm whether or not the called terminal is a handoff (104) (205), the short message reception signal is transmitted to the corresponding HOC (hand off control) processor ID through the information received from the PCC (20) block.

Accordingly, the HOC 22 transmits a short message reception signal to the HOC 32 block in the second electronic switching center 30 to be served (206).

Accordingly, the HOC 32 transmits the received short message reception signal to the PCSI 34 block (207), starts a timer and waits for a reception response (208).

As described above, according to the present invention, the TDX-10 PCX is implemented in the TDX-10 PCX before the TDX-10 PCX in the idle state, terminal busy state, or terminal handoff state, The function of the electronic exchanger is improved.
