The present invention relates to a method of receiving subscriber information in an electronic switching system, and more particularly, to a method of receiving information on an originating subscriber provided by an originating exchange.

Conventionally, the information of the large station and the originating subscriber is transmitted and received using R2 signaling or No.7 signaling. This signaling method uses MF-GP (Multi Frequency Gapless Packet) signal common sense to obtain outgoing subscriber information provided from the originating exchange so that the destination exchange can use it to provide call service or billing before, during, or after call setup between the exchanges. Provide the function.

FIG. 1 is a schematic diagram showing the flow of trunk line signals (LS) and trunk register signals (RS) transmitted and received to exchange outgoing subscriber information between an originating exchange and a destination exchange. When the originating exchange requests ANI to the originating exchange, the originating exchange provides the originating exchange information to the called exchange.

FIG. 2 is a chart showing EOGS frequency used for each information used to transmit and receive information of calling subscriber in MF-GP signaling.

3 is a schematic diagram showing information about a calling party to be transmitted, which is composed of a calling number (FS) and a calling class (Cx), and a start signal 13 is used to indicate the start of the calling number (FS), and is continuous. The repetition signal is used to distinguish the same information. At this time, the originating class (Cx) is information necessary for limiting the charge or the call in the destination exchange.

In transmitting the information, the originating exchange sends the start signal 13 for a certain time, and then continuously transmits the next information for the same time without a gap between the information, while the destination exchange transmits at least 10 pieces of information including repeated information. It can only be analyzed and processed.

Accordingly, the present invention provides information on a method of receiving subscriber information in an all-electronic exchange that uses the MF-GP signaling method, which is an inter-station register signaling method, in the all-electronic exchange. The purpose is to provide.

Hereinafter, the present invention for achieving the above object, in the electronic switchboard to communicate with the power using the MF-GP signaling scheme D: a first step of selecting a specific MF-GP channel from each MF-GP channel ; Connecting the specific MF-GP channel to a transmission path between stations; Transmitting a call request signal to a power station; A fourth step of receiving caller information transmitted by the power station; A fifth step of storing the received outgoing callout information in a specific database when reception of the callout information is completed; And a sixth step of releasing the specific MF-GP channel.

Looking at the embodiment of the present invention as described below is as follows.

4 is an internal configuration of the switch to which the subscriber information receiving method is applied in the electronic switch according to the present invention. The call processing control processor 101, the inter-station signal control processor 102, the switch connection unit 103, and the MF-GP signal control are shown in FIG. A processor 104, an MF-GP signal interface device 105, and an inter-station signal interface device 106.

In the figure, the call processing control processor 101 is in charge of the overall control of one call processing and the control of the originating subscriber information transmission process.

The inter-station signal control processor 102 is connected to the call processing control processor 101 and transmits and receives signals between the counterpart exchange and the station via the inter-station signal interface device 106, and analyzes / processes the received inter-station signals.

The switch connecting unit 103 is connected between the call processing control processor 101 and the inter-station signal interface device 106 to connect a communication path between the calling subscriber and the counterpart exchange and a passage for transmitting and receiving the MF-GP signal.

The MF-GP signal interface device 105 is connected to the switch connection 103 to generate an MF-GP information resource and is composed of several MF-GP channels.

And the MF-signal control processor 104 is connected to the call processing control processor 101 to analyze / process the MF-GP signal received through the MF-GP signal interface device 105 and to perform the sequencing of the MF-GP signal. Control transmission.

FIG. 5 is a process flow diagram in the call processing control processor 101 according to FIG. 4, FIG. 6 is a process flow diagram in the inter-station signal control processor 102 in accordance with FIG. 4, and FIG. 7 is an MF in FIG. Processing flow in the GP signal control processor 104.

As shown in FIG. 5, the call processing control processor 101 determines whether information of the calling subscriber is required while processing one incoming call (201). If it is determined in step 201 that the caller needs to receive information, one available channel is selected from a plurality of MF-GP channels (202). The switch connection unit 103 is controlled to connect a path between the MF-GP channel and the corresponding transmission path so that the MF-GP signal can be transmitted and received on the transmission path between stations (203). The inter-station signal control processor 102 requests transmission of the calling number request signal (204). The MF-signal control processor 104 requests 205 an origination information request signal for the origination information request. Wait for the originating call to complete (206).

As shown in FIG. 6, the inter-station signal control processor 102 receives a call request signal transmission request (301). A call request signal is transmitted over the inter-station transmission path (302). It waits in the call receiving state (303).

As shown in FIG. 7, the MF-signal control processor 104 receives a call origination request signal transmission request (401). The information associated with the selected MF-GP channel is initialized (402). Signal transmission and reception secretion in the MF-GP channel is performed (403). 404 sends an outgoing information request signal for a period of time via the MF-GP signal interface device 105. In a waiting state for receiving outgoing information, it waits for a signal related to outgoing information to be received (407). Wait for the next signal to be received in the outgoing information receiving state (408). It is determined whether the next signal is received (409). When the next signal is received, after storing the information, the received information is analyzed (410). As a result of the analysis, it is determined whether the caller needs to receive more information (411). If the receiving information is less received, wait for the reception of the next signal in the receiving information, and if received, the call processing control processor 101 reports the completion of the calling reception including the calling party information and ends the processing (412). ).

When the call processing control processor 101 receives the call origin reception completion report (207), the call processing control processor 101 stores the call origin information in the database (208). Controlling the switch connection unit 103 cuts the MF-GP path that was connected on the inter-station transmission path for MF-GP signal transmission (209). The inter-station signal control processor 102 requests the transmission of the call number cancellation signal and ends the process (210).

The inter-station signal control processor 102 determines (304) whether a call origination cancellation signal transmission request is received. When the call cancellation signal transmission request is received, the transmission of the call cancellation signal is started on the transmission path between the stations and the processing ends (305).

As described above, the present invention uses the MF-GP signaling method, which is an inter-station register signaling method, in an electronic switching system to receive information on the originating subscriber through the inter-station transmission path. Therefore, there is an effect of facilitating the provision of the call service of the destination exchange to the calling subscriber or the charging of the calling subscriber.
