Multi-way multiplex communication system and method of assigning channel in the same
First Claim
1. A multi-way multiplex communication system comprising:
- (a) a subsidiary station covering terminals to each of which an analog line, a basic rate interface (BRI) line and a primary rate interface (PRI) line are connected; and
(b) a base station which assigns the requisite number of time slots to thereby make radio communication with said subsidiary station in dependence on the number of vacant time slots between said subsidiary station and said base station, wherein said base station (b1) defines a subscriber class which determines an order in using a time slot to make radio communication with a H-channel terminal, (b2) monitors vacant time slots on receipt of a request of making a call, from said H-channel terminal, and (b3) controls call connection, based on said subscriber class, when it is impossible to connect a call because of shortage of vacant time slots, thereby ensuring a time slot for said H-channel terminal to make radio communication between said subsidiary station and said base station.

Abstract
A multi-way multiplex communication system includes (a) a subsidiary station covering terminals to each of which an analog line, a basic rate interface (BRI) line and a primary rate interface (PRI) line are connected, and (b) a base station which assigns the requisite number of time slots to thereby make radio communication with the subsidiary station in dependence on vacant time slots between the subsidiary station and the base station. The base station defines a subscriber class which determines an order in using a time slot to make radio communication with a H-channel terminal, monitors vacant time slots on receipt of a request of making a call, from the H-channel terminal, and controls call connection, based on the subscriber class, when it is impossible to connect a call because of shortage of vacant time slots, thereby ensuring a time slot for the H-channel terminal to make radio communication between the subsidiary station and the base station.

2. A multi-way multiplex communication system comprising:
-
(a) a subsidiary station covering terminals to each of which an analog line, a basic rate interface (BRI) line and a primary rate interface (PRI) line are connected; and
(b) a base station which assigns the requisite number of time slots to thereby make radio communication with said subsidiary station in dependence on the number of vacant time slots between said subsidiary station and said base station, said subsidiary station including an informer which informs a H-channel terminal of whether a call can be made, based on information received from said base station, said base station including;
(b1) a time slot manager which manages said vacant time slots;
(b2) a subscriber data manager which defines a subscriber class for each of terminals which subscriber class determines an order in using a time slot to make radio communication with a H-channel terminal;
(b3) an input device through which said subscriber class is input to said subscriber data manager; and
(b4) a time slot capture controller which, when it is impossible to make a call because of shortage of vacant time slots, controls a time slot, based on said subscriber class. - View Dependent Claims (3)

4. A method of assigning a channel in a multi-way multiplex communication system comprising:
-
(a) a subsidiary station covering terminals to each of which an analog line, a basic rate interface (BRI) line and a primary rate interface (PRI) line are connected; and
(b) a base station which assigns the requisite number of time slots to thereby make radio communication with said subsidiary station in dependence on the number of vacant time slots between said subsidiary station and said base station, said method comprising the steps of;
(a) storing a subscriber class into said base station for each of terminals, said subscriber class determining an order in using a time slot to make radio communication with a H-channel terminal;
(b) monitoring vacant time slots on receipt of a request of making a call, from a terminal belonging to a first class among said subscriber class, said step (b) being to be carried out by said base station;
(c) informing said subsidiary station that it is impossible to assign a time slot, when a call cannot be made because of shortage of vacant time slots, said step (c) being to be carried out by said base station; and
(d) informing said H-channel terminal of inability of making a call, said step (d) being to be carried out by said subsidiary station. - View Dependent Claims (5, 6, 7, 8, 9)
