How to Handle Short Message Incoming by Switchboard

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a short message incoming of an electronic switchboard, and in particular, an incoming processing function among short message service functions according to an IS-637 protocol structure applied between a personal communication exchange and a short message center. The present invention relates to a method for processing a short message incoming of an electronic switch, which is suitable for implementing the TDX-10 PCX electronic switch.

In this regard, the short message service, which is one of the supplementary services of the mobile communication and personal communication service, is commercially available in Europe, etc., and in our view of exporting the mobile communication and personal communication exchange, the implementation of the short message service is the It is necessary to improve various functions.

With this in mind, the TDX-10 PCX electronic switch will implement a short message service incoming function based on the IS-637 protocol structure.

An object of the present invention is an electronic switch that can implement the incoming processing function of the short message service function in the TDX-10 PCX electronic switch in the idle state of the terminal, the busy state of the terminal, or the hand off state of the terminal. The present invention provides a method for processing short message receipt.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

Referring to FIG. 1, FIG. 1 is a block diagram to which a short message incoming processing method of an electronic switch according to the present invention can be applied, and includes a first electronic switch (TDX-10 PCX electronic switch) 10, It consists of a second electronic switch (TDX-10 PCX electronic switch) 30, the first electronic switch 10 performs the exchange function of the subscriber and the second electronic switch 30 also exchanges the subscriber It performs a function, the first and second electronic switch 10, 30 may communicate with each other through a predetermined communication line to exchange subscribers with each other.

Referring to Figure 2 the present invention made as described above is as follows.

Figure 2 is a flow chart showing step by step an embodiment of a method for processing a short message incoming of the electronic switch according to the present invention.

That is, in the idle state of the terminal (not shown in the drawing), the busy state of the terminal, or the handoff state of the terminal, the base station controller (not shown in the drawing) is transferred from the base station controller (not shown in the drawing) to the first electronic switch 10. The short message incoming processing procedure transmitted from the first electronic switch 10 to the second electronic switch 30 is as follows.

First, the short message incoming signal transmitted to the LRSC 12 block, which is the mobility management map matching control block in the first electronic switch 10, is transmitted to the LCC 14 block, which is a visitor location register (VLR) call processing block. The LCC 14 block transforms this into an internal signal form and transmits it to a short message control (SMCO) 16 block, which is a short message control block (002).

Next, the SMCO 16 block checks the state of the called terminal through the information received from the LCC 14 block (003), and when the called terminal is in the dormant state, the SMCO 16 block is shortened to a PCS interface (PCSI) 18 block, which is a PCS matching block. The PCSI 18 block sends the short message incoming signal to the corresponding base station controller (004) and starts the timer to wait for a reception response (005).

When the called terminal is in a call state to check the state of the called terminal in step 003, the PCC (PCS call control) 20 block, which is a mobile call control block, for checking whether the called terminal is handoff or not. If a request is made (104) and the destination terminal is not handoff, it transmits a short message incoming signal to the corresponding PCSI 18 process ID through the information received from the PCC 20 block (105).

The PCSI block 18 then sends a shortened message incoming signal to the base station controller 106 and starts a timer to wait for a reception response (107).

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

Accordingly, the HOC 22 block transmits a short message incoming signal to the HOC 32 block in the second electronic switch 30 to be serviced (206).

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

As described above, the present invention implements the TDX-10 PCX switch by implementing the incoming processing function of the short message service function in the TDX-10 PCX electronic switch in the idle state of the terminal, the busy state of the terminal, or the handoff state of the terminal. There is an effect that the function of the electronic exchanger is improved.
