Abstract

PURPOSE:To simplify the control and to improve the throughput by commanding set and release of line switching connection or packet switching connection by a switching controller based on a control command in a signal form common to the line switching mode and the packet switching mode from a call controller. CONSTITUTION:A call controller 4 processes the call control signal from common signal lines 9 and a common line controller 6, which processes the signal of inter-office lines 7, and the call control signal from a subscriber's line controller 5, which processes signals of subscriber's lines 8, to control the call connection. The call controller 4 transmits a common control signal 12 of the signal form common to a line switching control signal 10 and a packet switching control signal 11 to a switching controller 3 to integrally control the line switching connection and the packet switching connection of a cross point switch and a packet switching switch 2. Thus, the control is simplified and the throughput of switching operation is improved.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a circuit switching mode/packet switching mode integrated switching control system in an ISDN switching system that provides circuit switching mode/packet switching mode services.

[Conventional technology]

Conventionally, in this type of switching system, circuit switching and packet switching services are provided by combining a circuit switching device and a packet switching device and transmitting and receiving signals associated with switching operations between the two switching devices.

[Problem to be solved by the invention]

The conventional configuration described above has the problem that the control method is complicated due to signal transmission and reception between both exchanges, and the processing capacity of the exchange operation is restricted. Furthermore, since line switching and packet switching are performed in separate exchanges, it is necessary to provide additional service processing common to both exchange services in both exchanges, which is not economical.

[Means to solve the problem]

The circuit switching mode/packet switching mode integrated switching control system of the present invention is a crosspoint that performs circuit switching operation in a switching system that accommodates interoffice lines and subscriber lines and provides an exchange IfA function in circuit switching mode and packet switching mode. a packet switching switch disposed after the crosspoint switch, a switching control device for controlling the crosspoint switch and the packet switching switch, and a call control device; The switching control device selects either the crosspoint type switch or the packet switching switch based on a control command in a signal format common to circuit switching mode and packet switching mode from It is configured to command.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Referring to FIG. 1, which shows an embodiment of the present invention, a crosspoint switch 1 is a switch that performs circuit switching connections, and a time division switch 2 is a switch that establishes packet switching connections (logical connections).

Switch 1 receives circuit switching control signal 10 from switching control device 3.
and the switch 2 receives the packet switching control signal 11 and performs the switching operation. The call control device 4 includes a common signal line 9 that processes signals on the interoffice line 7 and a common line control device 6.
It processes the call control signal from the subscriber line control device 5 which processes the signal of the subscriber line 8, and performs call connection control. In addition, the call control device 4 is connected to the exchange control device 3.
By transmitting a common control signal 12 in a signal format common to circuit switching mode (circuit switching control signal 10) and packet switching mode (packet switching control signal 11) in pairs,
The circuit switching connection and packet switching connection of the switch 1.2 can be controlled in an integrated manner. Figure 2 shows circuit switching control signal 10, packet switching control signal 11 and common control signal 1.
An example of signal format No. 2 is shown below.

〔Effect of the invention〕

As explained above, according to the present invention, the switching control device selects either the crosspoint type switch or the packet switching switch based on the control command in the signal format common to circuit switching mode and packet switching mode from the call control device. By instructing the setting/cancellation of a circuit switching connection or a packet switching connection, the circuit switching mode and the packet switching mode can be controlled in an integrated manner. Also,
It becomes possible to use a common signal format for circuit switching mode and packet switching mode, simplifying the control method and improving processing capacity9.Furthermore, various additional service processing can be provided for common circuit switching and packet switching services. is possible, and the service can be expected to be scalable and economical.
