KR100258126B1 - Method for direct call allotment in full electronic telephone exchange - Google Patents

Abstract

PURPOSE: A method for assigning a private transit call in a full electronic exchange is provided to process a call at a desired time point by assigning one transit line to a fixed out-going number. CONSTITUTION: After processing trunk data(201), a TCC allows to assign a trunk to an out-going subscriber(202). If the out-going subscriber is an object of the priority, the SNS assigns a fixed transit line to the out-going subscriber(204). After this, the TCC and an LC process subscriber data and transit data by using the fixed transit line such as a private transit line(205). Because the assigned transit line is used like the private transit line, the out-going subscriber performs a call access process at a wanted time point.

Description

Dedicated Relay Call Allocation Method of Electronic Switching System

The present invention relates to a full electronic telephone exchange, and in particular, in a DTS-1100A (improved) small-capacity exchanger, a dedicated relay call allocation method of an all-electronic exchange switch capable of assigning a dedicated relay with priority. It is about.

In general, the system of the DTS-1100A Enhanced Electronic Switching System is commercially available such as voice (Local / Tandem), CENTREX, ISDN (2B + D, 30B + D), and common line signaling (CCS NO.7). It has been developed to play a major role in a comprehensive information communication network that can accommodate both services and commercialized services as one system.

The main design concept of the DTS-1100A retrofit is the open archi-tecture, which provides flexibility and modularity to make the system easy to expand and modify, and to easily improve the system as technology advances. ) Is adopted.

In other words, the system structure is designed to minimize the impact of technological development, and is designed in consideration of economics to provide advanced services to subscribers at a more economical price.

In the conventional DTS-1100A small-capacity exchanger, when an outgoing subscriber attempts to connect a call, if a busy condition occurs in the relay line because the service limit is exceeded, the call is made before the relay line is idle. There was a problem that can not.

The present invention has been made to solve the above problems, the purpose of which is to assign a relay line 1: 1 by using the Man & Maching Communication (hereinafter abbreviated as MMC) the calling number having a priority The purpose of the present invention is to provide a dedicated relay call allocation method for an electronic switch that can occupy relay calls.

The present invention for achieving the above object relates to a dedicated relay call allocation method of the electronic switchboard, the step of inputting trunk data to the main processor so that the calling subscriber can be assigned to the relay line using the man & machine communication; ; After receiving and processing the trunk data at the main processor, permitting the trunk allocation of the calling subscriber in a leased line concept; Re-executing trunk data if the calling subscriber is not the priority object by checking whether the calling subscriber is given priority to be given a dedicated relay line; If the calling subscriber is a priority object, allocating a specific trunk line channel; When the specific relay line channel allocation is completed, the subscriber processor and the relay line data are processed by the main processor and the line processor using the dedicated relay line.

Hereinafter, the objects and features of the present invention will be described in more detail with reference to the accompanying drawings so that the objects and features of the present invention can be more clearly understood.

1 is a block diagram of a dedicated relay call allocation method of an electronic switch according to the present invention, a line processor (hereinafter abbreviated as LP) 10, trunk and analog line control (Trunk and Analog Line control) Control (hereinafter abbreviated as LC) 12, Main Processor (hereinafter abbreviated as MP) 20, Trunk Call Control (hereinafter abbreviated as TCC) (22) And Subscriber Call Control (hereinafter abbreviated as SCC) 24, Switching & Number Translation Subsystem (hereinafter abbreviated as SNS) 26, and I / O processor ( Input Output Processor: hereafter referred to as IOP) 30.

The LP 10 internally includes an LC 12, and a calling subscriber registered with a dedicated relay call detects a hook off / hook on signal, and then detects a hook off signal among the detected signals. After dialing, it monitors the status of the relay line so that the call can be connected without delay.

The MP 20 internally includes a TCC 22, an SCC 24, and an SNS 26, which is connected to the LC 12 in the LP 10, and which relays outgoing subscribers registered with a dedicated relay call. It is a higher processor that handles calls and performs maintenance functions for system status.

The TCC 22 is a trunk line call control block residing in the trunk line subsystem, which is called, incoming and relayed for route occupied signal points for dialing and digit signals transmitted from the LC 12 in the LP 10. Performs call processing, controls between the SCC 24 and the SNS 26 so as to facilitate call connection, and relay call processing so that a call connection can be made between a second subscriber, which is a called subscriber and a large station, using another exchange. Perform

The SCC 24 is a subscriber call control block, which is connected to the TCC 22 to perform local call control, outgoing call control, and incoming call control processing, generates billing information and collects statistical data, and then through the TCC 22. Transmit to SNS 26.

The SNS 26 receives a telephone number transmitted according to a dedicated relay call process, and internally translates a number translation, a time switch, a telephone device controller, and subscriber data matching. A subscriber unit (Subscriber Data Handling), analyzes the number information transmitted from the TCC (22), performs the function of checking the use and destination location, and retransmits to the TCC (22), and with the IOP 30, which is an input / output processor It is interfaced to receive trunk data information using MMC.

The IOP 30 is an input / output processor that is in charge of input / output link control, and performs message data handling for analyzing and managing messages input and output through the input / output link, and state management for each input / output link. And Input Output Process Management, which performs I / O control functions, Disk Handling, which performs file management functions for hard disks in a PC, and creation of system data and system software. It consists of Data Generation which performs matching function and Data Extraction which performs the function of extracting station data from the system package in operation, and SNS trunk data for call processing using MMC. 26 is the processor to input.

The overall block diagram of the dedicated relay call allocation method of the exchange according to the present invention configured as described above has been described, and FIG. 2 illustrates a detailed flowchart of the present invention for the dedicated relay call allocation method of the exchange.

The trunk data is input to the TCC 22 via the SNS 260 so as to allocate a relay line to the calling subscriber by using the MMC for call processing (step 200).

After processing the trunk data in the TCC 24 (step 201), the trunk subscriber is allowed to assign a trunk in the concept of a leased line (step 202).

In SNS 26, it is determined whether the calling subscriber has checked the priority to which the dedicated relay line is assigned (step 203). If it is not the priority target for the calling subscriber, step 201 is executed again.

If it is a priority target for the calling subscriber, then a specific trunk line channel is assigned (step 204).

When the specific trunk line channel assignment is completed, the subscriber data and the trunk line data are processed by the TCC 22 and the LC 12 using the dedicated relay line (step 205).

Therefore, one dedicated channel of the 32 channels is designated as the calling subscriber between the TCC 22 and the LC 12 so that the calling subscriber can perform call connection processing at a desired time.

As described above, in the present invention described above, when all the channels are busy, the call cannot be made until the relay line channel is idle, and one relay line is assigned to a specific call number, and then assigned. The effect is that you can proceed with the call at the time you want by using a line as a dedicated line concept.
