摘要:
A system and method provide the ability to collect, store and transmit information statements concerning satellite communication system use. The satellite system may collect billing information, such as roaming data, network use in terms of both total time and total bandwidth and functionality utilized on a user by user basis. Further, the satellite system may collect network usage information from the totality of users of a satellite system. The billing information and network usage information may be collected and stored on-board satellite(s) in a network in a data structure including a database. This information may then be collected, organized and transmitted to a variety of users in the earth segment of the system.
摘要:
The invention concerns a method of transmitting charge data to the subscriber connectors and for emitting charge pulses to the subscriber connector a/b interface in a local switching and transmission system which is arranged as a local radio cell, consisting of a central stationary radio station and a plurality of decentralized subscriber connectors, and, as a local or private branch exchange, is connected to the public telecommunication system. According to the invention, the base station of each radio cell stores a distance zone table which is adapted to the location and which contains the clock pulse data for calculating the charges, for the local area and all telecommunication connections outside the local area. During an outgoing communication from a radio subscriber, the call number selected by this subscriber is compared automatically with the distance zone table and the appropriate clock pulse data is removed and transmitted to the subscriber connector which generates standard charge pulses according to the clock pulse transmitted and emits them to the a/b interface. The standard charge pulse of 12 kHz or 16 kHz cannot be transmitted via radio channels whose transmission band-width is restricted to the speech band from 300 Hz to 3400 Hz. As a result of the solution applied, the charge pulse does not have to be transmitted, as in as other, conventional processes, as a substitute signal embedded in the speech band, which, according to experience, would disturb the transmission of modem and fax machine signals.
