Abstract

PURPOSE:To attain packet exchange and line exchange in a single system by providing a call identification section to identify a form of call and allocating a time slot for a packet exchange and for a line exchange based on the identification by the call identification section. CONSTITUTION:A call coming from a packet form terminal equipment 101 and a line form terminal equipment 102 is given to a call identification section 303 in an exchange 301 via an out-channel on a highway 401. Then based on the identification by the call identification section a time slot allocation section 304 allocates a communication in-channel to a packet time slot or a line time slot on a highway 401. As a result, a packet form communication in-channel data is given to a packet buffer 305 and packet exchange is applied and a line form communication in-channel data is subject to line exchange by an exchange switch section 302. Thus, the packet exchange data and the line exchange data are processed simultaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a switching system, and particularly to a switching system that simultaneously exchanges packet type data and line type data.

[Prior Art] Conventional switching systems include packet switching systems and circuit switching systems. These systems separately and independently perform exchange processing for packet type data and line type data.

[Problems to be Solved] The conventional switching systems described above had separate packet switching systems and circuit switching systems, which required separate switching networks and the problem of not being able to share equipment. Ta.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an exchange system capable of simultaneously exchanging packet type data and line type data.

[Means for Solving Problems] In order to achieve the above object, the switching system of the present invention includes a call identification unit that identifies the call type of packet switched data and circuit switched data input via an out-channel on the highway. Based on the identification by this call identification unit, the communication inch channel is assigned to the packet time slot or line time slot, and the inch channel slot on the highway is dynamically changed and reassigned according to the size of the communication call. This configuration includes a time slot allocation section for exchanging inch-threaded channel data for packet-based communications, a packet switching section for exchanging inch-thickness data for line-based communications, and a line switching section for exchanging inch-thickness data for line-based communications.

[Example] Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 is a block diagram of an exchange system according to an embodiment of the present invention.

In the figure, 101 is a packet type terminal, 102 is a line type terminal, and 201 is a line concentrator.

Further, 301 is an exchange, 401 is a highway, and the exchange 301 and the line concentrator 201 are connected via the highway 401.

On the other hand, in the exchange 301, 302 is an exchange switch section, 303 is a call identification section, 304 is a time slot allocation section, and 305 is a packet buffer section.

In the above configuration, calls originating from the packet type terminal 101 and the line type terminal 102 are input to the call identification unit 91 (303) via an out channel on the highway 401. Based on this, the time slot allocation unit 304 allocates the communication channel to a packet time slot or a line time slot on the highway 401.

As a result, the inch-thread channel data for packet-based communication is input to the packet buffer 305 for packet exchange, and the inch-thread channel data for line-based communication is switched for line by the switching switch section (line switch) 302.

Furthermore, as a result of the identification by the call identification unit 303, the time slot allocation unit 304 dynamically changes the inch-way slot on the highway 401 depending on the size of both types of communication calls. Therefore, switching is performed efficiently depending on the communication situation.

In this way, this embodiment provides a function for identifying whether each call is from a packet-switched data terminal or a circuit-switched data terminal in a switching system that performs call control using out-channels, and a function for identifying each call. It has a function of allocating time slots on an inch channel based on the identification result by the function, and a function of dynamically allocating time slots according to the rate of call occurrence. Then, packet switched data and circuit switched data can be processed simultaneously.

[Effects of the Invention] As explained above, the present invention allocates time slots for packet switching and circuit switching and dynamically changes the time slots to perform packet switching and circuit switching in a single system. This has the effect of providing an exchange system that allows for
