Abstract

PURPOSE:To reduce number of standby channels and to attain effective utilization of a radio wave by detecting a call control signal included in layer information and assigning only a required radio channel between a base station equipment and a subscriber station equipment depending on the content. CONSTITUTION:When a layer 3 information signal 'call setting' is sent to a subscriber line exchange 1 through a set D channel, a layer 3 processing section 11 detects the signal to apply call setting processing and gives a request of setting B channel to a radio channel management control section 23 at the same time. The control section 23 assigns the B channel between the base station equipment 2 and the subscriber station equipment 4. The equipment 4 starts a Bi channel upon the receipt of the assignment notice and informs the end of Bi channel start to the equipment 2 through the D channel. When the line assignment is finished, the control section 23 informs the end of B channel setting to the exchange 1. Thus, a terminal equipment 5 and the exchange 1 are brought into communication.

A startup completion signal is sent to the terminal device 5 via the layer 1 processing unit 42.

Upon receiving the notification of activation completion, the radio line management control unit 23 of the base station device 2 notifies the subscriber line exchange 1 of the terminal activation via the layer 1 processing unit 21.

Furthermore, at the end of the call, the terminal device 5 sends a terminal stop signal to the subscriber station device 4. When the subscriber station device 4 receives the terminal stop signal, it sends a line release request to the base station device 2. When the base station device 2 receives a line release request, it releases the line all at once and notifies the subscriber station device 4 of the information. When the subscriber station device 4 receives the line release notification, it notifies the base station device 2 of the line release confirmation, and
A stop completion signal is sent to the terminal device 5.

When the base station device 2 receives the notification of line release confirmation, it notifies the subscriber line exchange 1 that the terminal is stopped.

[Problem that the invention seeks to solve]

As described above, in the conventional wireless line setting method, a wireless line is allocated to each subscriber line. For this reason, for example, 2B
+D, that is, a user/network interface that includes two information lines and one control line, actually performs subscription based on start signals and stop signals from terminal equipment or start signals and stop signals from subscriber line exchanges. Three types of lines were set up at the same time, regardless of the number of lines used by the person. For this reason, even lines that are not actually used are allocated, making it impossible to use wireless lines effectively and resulting in a low subscriber capacity.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless line setting method that solves the above problems and allows effective use of wireless lines.

[Means for solving problems]

In the wireless line setting method of the present invention, the means for setting up a wireless line between a base station device and a subscriber station device establishes a communication wireless line for each unit line using a call control signal defined by an ISDN user/network interface. It is characterized by including means for allocating.

[For production]

The call control signal specified at the user-network interface, that is, the call control signal included in layer 3 information, is detected, and based on its contents, the necessary radio Only lines are allocated between base station equipment and subscriber station equipment. Because it is dynamically allocated according to the occurrence of a call, the number of backup lines is extremely small, allowing for effective use of radio waves.
