KR970019227A - No.7 ISUP incoming line call processing method for ISDN electronic switchboard - Google Patents

Abstract

The present invention implements a function for a service having a 384 Kbps transmission rate through the common channel signaling No.7 ISUP in an ISDN exchange, thereby providing a 384 Kbps multislot call service required by an ISDN subscriber in a large country. 7 The purpose is to provide a method for handling ISUP attestation line.

In the ISDN exchange, since one channel has a fixed transmission rate of 64 Kbps, in order to provide a 384 Kbps multi-slot call service, only 6 channels must be occupied consecutively so that the present invention provides a 384 Kbps multiple in the ISDN switch. In order to provide slot call service, it consists of 6 channel occupancy procedures required in No.7 ISUP incoming line call processing function and matching procedure between incoming line call processing control and ISDN incoming subscriber processing function.

Description

3 is a service processing flowchart of an ISUP authentication line call processing process of an integrated information communication network electronic switching system according to the present invention.

Claims (4)

An RCO (Route Control) block that manages the status of routes and lines, an UPSN (IDSN User Part Control) block that performs inter-station call control when the No. 7 ISDN user part is used as the inter-station signaling method, The Digital Circuit Subscriber Control (DCC) block that controls ISDN subscriber call processing is applied to an integrated telecommunications network switch that includes an NTR (Number Translation) block that analyzes the number of the called party. In the No.7 ISUP incoming line call processing method for processing a service, when a request for 384 Kbps call service is requested by examining the transmission medium request of the incoming line call processing request message (IAM) from the other station, the relay line number loaded in the IAM is set to 32. The first step of dividing the remainder, and whether the calculated remainder is 1 or 7 or 13 or 20 or 26. A second step of allowing the channel value to be used for a channel for providing a multi-slot call of 384 Kbps, and creating an incoming line call processing process with reference to the service providing channel information, and making the main process transition to an idle state. Step 3, receiving incoming call notification that the incoming line call processing request is received from NTR to the subscriber of its own country by requesting translation of the number into NTR, and requesting translation of called number by NTR, and called subscriber processing block The fifth step of receiving the incoming call notification from the incoming DCC, performing the switch connection to the six selected channels, and notifying the DCC of the information on the outgoing subscriber loaded on the IAM and the switch connection completion after the switch connection is completed. In step 6, when an alerting is received from the DCC, an address reception completion message is sent to the originating station. Step 7 is to send a response message to the calling station when receiving the message, and to receive the recovery message from the calling station; when receiving a recovery message from the calling station, the DCC notifies that the calling subscriber has recovered and sends a recovery completion message in response to the calling station. No.7 ISUP incoming line call processing method, characterized in that the eighth step incoming call processing process for transmitting comprises putting a channel provided in the 384 Kbps multiple slot into an idle state, and disconnecting and extinguishing the connected switch. . The method of claim 1, wherein if the remainder calculated in the second step is 1 or 7 or 13 or 20 or 26, and if it is not one of these values, a recovery message is sent to the power to initiate a call release procedure and the recovery is completed from the power. And a tenth step of transitioning to an idle state upon receiving the message. The method of claim 2, wherein in the step 2, when the remainder is one of 1, 7, 20, and 26, the relay line number, the relay line number + 1, the relay line number + 2, the relay line number + 3, the relay line number + 4, and the relay line number + The channel value of 5 is used for the channel for providing multi-slot call service of 384 Kbps, and if the remainder is 13, the relay line number, the relay line number + 1, the relay line number + 2, the relay line number + 4, the relay line number + 5, the relay line A No.7 ISUP incoming line call processing method, wherein a value of number +6 is used for a channel for a multi-slot call service of 384 Kbps. 4. The call forwarding translation request of claim 4, wherein the called party translation request in the fourth step includes related information so that the ISDN subscriber of the calling station requests 384 Kbps of multi-slot call service when the NTR requests the occupancy to the DCC. No.7 ISUP incoming line call processing method, characterized in that the request is made. ※ Note: The disclosure is based on the initial application.
