Document Type and Number:
Japanese Patent JP3001534
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To omit the slot allocation of a B channel which is not always necessary. SOLUTION: A 1st slave station 3 having received a message 101 sent from an origination-side ISDN terminal 61 belonging to the 1st slave station 3 among slave stations requests a base station 2 connected to the ISDN network to allocate the time slots of D channel and B channel, so that the time slots of D channel and B channel are assigned to the origination-side ISDN terminal, 1st slave station 3, and a ground station 2. The stations 2 and 3 detect whether or not the 1st slave station 3 that the origination-side ISDN terminal 61 belongs to and the 2nd slave station that the termination-side ISDN terminal belongs to are the same station by monitoring the 1st message 101, and when detected that they are the same, the time slot of the B channel is not assigned between the ground station 2 and 1st slave station 3. Thus, the omitted time slots are released for a 3rd party.
