Abstract

PURPOSE:To simplify the titled charging system by performing the charging processing through an exchange system of a repeating exchange station or a terminal office. CONSTITUTION:This communication system includes an existing repeating exchange station or a terminal station 1, switchboard 2, control station 3 of a satellite communication system, satellite 6, remote earth stations 4 and 5, and remote subscribers 7 and 8. The station 3 is provided with a demand assignment controller 11, channel controller 12, radio rack 13 and an antenna 14. The stations 4 and 5 contain a demand assignment remote controller 15, the controller 12, the rack 13 and the antenna 14 respectively. A semi-automatic operation is secured when a call is connected to z switchboard 2, and a conversation is carried out between the subscriber 7 or 8 and the switchboard 2. Then a subscriber 10 is connected, and the charging is processed by the switchboard 2 or the exchange 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to billing schemes for domestic satellite communication systems, and more particularly to billing schemes for remote subscribers connected directly to remote earth stations.

Conventionally, for calls made by remote subscribers connected to remote earth stations of the domestic satellite communication system (DOMSAT), all billing processing will be performed at the switching equipment of the control station that will be newly incorporated into the DOM8A'I' system. However, the drawback was that the function of the control station was extremely large29, which was a factor in reducing the cost of the satellite communication system.

The present invention is inspired by a call originating from a remote subscriber directly connected to a remote earth station, and is applied to a switch at a trunk switching station (TS) or terminal station (LS) of an existing network connected to a control station. By handling semi-automatic calls and entrusting the billing processing function to the switching system of the relay exchange ('1'S) or terminal station (LS), economicalization of the intra-local satellite communication system, and raftware and hardware. This is intended to simplify the process.

According to the present invention, in a domestic satellite communication system consisting of one control station that allocates frequencies on demand and is connected to an existing network, and a large number of remote earth stations controlled by the control station, In the case of a call originating from a remote subscriber directly connected to the control station, the call is handled semi-automatically at the switching center of the existing network connected to the control station or the switching center of the terminal station, and the switching/exchange of the switching center or terminal station of the existing network connected to the control station A billing method for a domestic satellite communication system is obtained, which is characterized in that billing processing is performed in the system.

FIG. 1 is a block diagram showing an embodiment of the present invention. This communication system is equipped with an existing relay switching center (TS) or terminal station (LS).
) 1 and % the switching center 2 of the relay switching center (TS) or terminal station (LS), the satellite communication system, and the control station 3 of the satellite (z!:, remote earth station controlled by the Off control station 3) 4. and a remote earth station 5 and a remote access '21 directly connected to said remote earth station 4.
'7 and a remote subscriber 8 connected from the remote earth station 5 via the terminal station 9, and the existing switching center IVC connected to the control station 3 accommodates the subscriber 10.

As a configuration of the satellite communication system, the control station 3 includes a demand assignment control device (DAC) 11, a channel control device (CHD) 12, and a radio rack (RF).
) 13 and an antenna (ANT) 14, and the remote earth station 4 and the remote earth station 5 are equipped with a task assignment remote device (DAR) 15.

Channel control unit (CHU) 12 and radio rack (RF)
13 and an antenna (ANT) 14.

In this embodiment, when a call is made from a remote subscriber 7 directly connected to a remote earth station 4, a frequency assignment request is issued by the remote earth station 4's DAR (DAR) xs, and the satellite Frequency assignment is performed by the demand assignment control device (DAC) 11 of the control station 3 via the transmitter 6, and the frequency number is sent to the originating remote earth station 4. The earth station 4 uses the assigned frequency number for the communication channel and dials and relays the called subscriber number. Since the demand assignment control device (DAC) 11 of the control station 3 can identify the calling earth station number, it recognizes that the calling earth station 4 is directly accommodating the subscriber.
It is converted into a switching board connection number and sent to the existing switching center 1. When the call is connected to the switchboard 2, the call is handled semi-automatically, and a conversation takes place between the remote subscriber name 7 and the switchboard 2, and the switchboard operator listens for the called party number and connects it to the existing switchboard 1. The switchboard 2 is connected to the subscriber 10
Alternatively, the exchange 1 performs billing processing.

On the other hand, when a call is made from a remote subscriber 8 accommodated in a terminal station 9 connected to a remote earth station 5, a frequency allocation request is issued by a maintenance assignment remote device (DAR) 15 of the remote earth station 5. Frequency assignment is performed by the demant assignment control device (DAC) 11 of the control station 3 via 6, and the frequency number is sent to the originating remote earth station 5.

The earth station 5 uses the assigned frequency number for the communication channel and relays the called subscriber number. The demant assignment controller ft (DAC) u of the control station 3 identifies the calling earth station number, identifies that the call is from a remote subscriber 8 connected to the terminal station (LS) 9, and connects the call to the switchboard. Directly relays the entire called party number without converting it to a number. 1, the call is connected directly to the called party lo accommodated in the existing exchange 1.

In that case, the billing process is performed by the terminal station 9 connected to the remote earth station 5.
It will be held at

The present invention can make the domestic satellite communication system economical and simplify the software and hardware.
