PURPOSE:To dispense with a connecting time for the control of a satellite loading switch and to improve the working efficiency of a satellite line by performing the control of the satellite loading switch so as to control a line classified by every area corresponding to burst allocation status classified by every area by setting the specified number of idle lines classified by every beam in advance. CONSTITUTION:The burst allocation of TDMA is performed by referring to a TDMA burst allocation state data base 9 between areas and the connection state data base 8 of the satellite loading switch at every call issuance from a slave station, retrieving the presence of a null time slot in a desired area, allocating a burst by selecting the null slot if it exists, connecting aline between corresponding slave station, and changing the data base 9. Meanwhile, the control of the satellite loading switch 3 is performed by referring to the data base 9 and the data base 8 independently from the call issuance from e slave station, reloading the memory for driving of satellite loading switch control circuit 5 so as to always secure the idle lines classified at every area, changing the connecting state of the satellite loading switch 3, and changing the connection state data base 8 of the satellite loading switch in a line control station 6. |
