Abstract

The present invention relates to an incoming call and a call processing method of an outgoing subscriber for service interworking of a telephone network subscriber in a telephone network matching device of a mass communication processing system. The purpose is to transmit the user's information to the network components such as IP and OAM in the new ACPS structure, and deliver the information received from the network components to the user. The method is as follows. When the calling subscriber attempts to retrieve the information, it gives the relay line occupancy signal from the public telephone network to the telephone network access subsystem of the mass communication processing system. The telephone network access subsystem system of the mass communication processing system transmits an occupancy response signal to the public telephone network in the idle task state, searches for the R2 channel, and occupies the R2 channel. The called party is collected by R2 signaling, occupies the TDLA channel, and reports the TDLA channel information to the TSPA. After trying TDLA HOO-OFF, it releases R2 channel by collecting calling number just like collecting called number. It reports the calling number to TSPA and detects the TDLA channel HOOK-OFF and attempts to connect between the calling subscriber's modem and the TDLA modem. If the modem is successfully connected, the initial screen of TSPA is transmitted to the subscriber and the subscriber access data service is provided. If the calling party wants to close the call, it asks TSPA to initialize the modem channel of the TDLA. Then, the TNPA relay is released and the task transitions to the idle state.

Description

Telephony call processing method in telephony network access subsystem in advanced communication processing system

The present invention relates to an incoming call and a call processing method of an outgoing subscriber for service interworking of a telephone network subscriber in a telephone network matching device of a mass communication processing system. In general, at the time when data communication is more important than voice communication by telephone, IP is accommodated in a packet switched data network (PSN), but a user who needs information is generally a public telephone network. (Public Swithed Telephone Nework, hereinafter abbreviated as PSTN). Therefore, there is a problem that it is difficult to communicate information between them and that important information is not available.

The present invention to solve the above problems by performing the telephone network matching and telephone call control messages, that is, call setup, call progress, call release function that is handled by TSNA, TDLA, HDPA, USTA (Universal Sigamling Tranceiver board Assembly) of TNAS, In the new Advanced Communication Processing System (ACPS) structure, which is different from the existing CPS, the information of users connected to the subscriber network is transmitted to IP and operation, administration and management (OAM) and other network components connected to other networks. The purpose is to perform the function of delivering the information received from the user to the user. In order to achieve the above object, the present invention is characterized by providing a relay line occupancy signal from a public telephone network to a telephone network access sub system of a large capacity communication processing system when the calling subscriber attempts to retrieve information. Transmitting an occupancy response signal to the public telephone network in the idle task state and searching for the R2 channel to occupy the R2 channel, collecting the called number by R2 signaling, occupying the TDLA channel, and reporting the TDLA channel information to the TSPA. And, after attempting TDLA HOO-OFF, collecting the calling number and releasing the R2 channel similarly to collecting the called number, and reporting the calling number to the TSPA and detecting the TDLA channel HOOK-OFF to detect the modem of the calling subscriber. Connection between the TDLA modem and the initial stage of the TSPA when a modem connection is sent. Transmitting a screen to the subscriber and providing subscriber access and data services; requesting the TSPA to initialize the modem channel of the TDLA if the calling subscriber wants to terminate the call; and releasing the relay call of the TNPA and the task is idle. Transition to a state.

In addition, the present invention, the telephone network matching portion uses the Telephony Network InterFace (TNIF) function of the existing ICPS, but the subscriber modem matching portion is configured to accommodate 8 channels 28.8KBPS per TDLA board. Open ACPS needs to accommodate various public networks such as PSTN, PSDN, Frame Relay Network, ISDN, ATM network, etc., so it has a different structure from the existing CPS and requires universal network access interface function. ACPS should have a structure that is easy to expand and contract to provide service interworking between various networks. Network interworking scope is largely divided into subscriber side and information provider side. Currently, there are a telephone network and a general information communication network in the network interworking with the subscriber, and a packet network, a frame relay network, an ATM network, and the Internet in the network interworking with the information provider.

ACPS accepts telephone network 11, integrated information communication network 12, data network 13, internet 14, frame relay network 15, ATM (Asynchrous Transfer Mode) network 16 in a modular form. . The High Speed Switching Fabric (hereinafter referred to as HSSF) subsystem 18 connects various types of network matching modules, service support module and communication processing module constituting ACPS at high speed and transports service traffic. Provides the function of the internal high speed interconnection network in charge of Network matching device interworking with subscriber side includes TNAS 111 and INAS 121, and network matching device interworking with information provider side includes PNAS 131, KNAS 141, FNAS 151, ANAS 161, and the like. There is this.

2 illustrates an interface communication module of TNAS for providing various communication services of ACPS to a user connected to a subscriber network. The telephone network matching device is a subsystem capable of serving 96 channels of subscribers by connecting digital PCM trunks up to 3 * E1. TDLA module 21 for interfacing with TNAS subscriber network, HSNA module 22 for interfacing with HSSF, and service processing (hereinafter abbreviated SP) module 23 for controlling and processing the service. It consists of.

The SP module 23 is composed of an FDPA 231 for processing functions such as subscriber modem speed determination, modem error detection, subscriber information transmission, reception, initialization and self-diagnosis, and a TSPA 232 for service processing and control. TSPA interfaces through HSNA and Main Processor System (MPS) buses. TSPA acts as a bus requester / arbiter. TSPA is also a Data Transfer Bus (DTB) master that can read / write 32/16 / 8-bit DTB slaves. TSPA handles interrupts and also handles local interrupts at levels 6 and 7 required by Multi-Funcution Peripheral (MFP) 1 and MFP2. TSPA has two channels for data transmission with other redundant TSPA. The C channel is a bidirectional 8-bit parallel channel and the D channel is a 32-bit parallel channel. The active TSPA can read / write 16M DRAM of the standby TSPA through the D channel. TSPA has an input port for fault monitors and an output port for hardware control. TSPA controls and monitors HDPA, HSNA and power alarms through the alarm port. TSPA uses Interprocessor Communications (IPC) dedicated communication processor for data communication with HDPA, and transmits data in an interrupt manner through 1M bytes of common memory. The processor for IPC communication communicates with each of the three HDPAs via the S Bus (Serial Communications Bus).

Figure 3 shows the TNAS call processing process of the relay call and ACPS of the telephone call originating subscriber. When the calling subscriber attempts to retrieve the information (S1), the PSTN gives the relay line occupancy signal to the TNAS of the ACPS (S2). The TNAS task of the ACPS transmits the occupied ACK signal to the PSTN network in the idle task state (S3) and then searches for the R2 channel (S5) to occupy the R2 channel (S6). After that, the called party is collected by R2 signaling (S7), occupies the TDLA channel (S8), and reports the TDLA channel information to TSPA (S9). Gurigo, after the TDLA HOO-OFF attempt (S10), collects the calling number as in the incoming call collection (S11).

After releasing the R2 channel (S12), the calling number is reported to TSPA (S13). By detecting the TDLA channel HOOK-OFF (S14), a connection attempt is made between the calling subscriber modem and the TDLA modem (S15). After that, upon successful modem connection (S16), the initial screen of TSPA is transmitted from the subscriber (S17). In addition, the subscriber access and data service is provided (S18), and if the calling subscriber wants to terminate the call (S19), the TSPA requests the modem channel initialization of the TDLA (S20). After the TDLA modem is initialized in the TSPA, the TNPA relay is released (S21), and the task transitions to the idle state (S22).

As described above, the present invention provides the data of a plurality of telephone network subscribers in a telephone network matching device of a high speed / capacity communication processing system as well as processes call processing of many subscribers in real time, and is executed in TNPA, HDPA, and TSPA of TNAS.
