Embodiment Construction

[0040] Detailed Description of Preferred Embodiments

[0041] The following will describe in detail the intercommunication equipment and method in the switching network according to the preferred embodiment of the present invention with reference to the accompanying drawings.

[0042] Figure 4a shows the interworking structure between the PNNI network and the B-ISUP network using the interworking function of the preferred embodiment of the present invention. Referring to FIG. 4 a , the PNNI network and the B-ISUP network utilize an interworking switch 40 to realize intercommunication. Local switches 45A, 45B are connected to interworking switch 40, matching users 46A, 46B through user network interfaces (UNI).

[0043] According to a preferred embodiment of the present invention, the interworking structure between the PNNI network and the B-ISUP network supports the connection between the PNNI interface 42 and the B-ISUP interface 43 in an interworking switch 40 . Utilize th...

Abstract

An apparatus and method for interworking at least two switching system networks is disclosed. According to the disclosure, interworking is possible by processing a call process message using only one interworking function for both networks. Accordingly, there is no need for interworking protocol such as the ATM Inter-Network Interface (AINI). Preferably, the two networks are a Private Network to Network Interface (PNNI) type network and a B-ISDN User Part (B-ISUP) type network, and an interworking function is coupled to both a PNNI interface and a B-ISUP Interface. Preferably, addresses are registered at each of the interfaces and messages to be transmitted between networks are converted from an origination network protocol to a destination network protocol according to an interworking function table.

Description

technical field [0001] The invention relates to a switching system network, in particular to a device and a method for realizing intercommunication in a private network interface (PNNI) network and a B-ISDN user part (B-ISUP) network. Background technique [0002] Interworking between networks means connecting networks with different characteristics to provide services. In order to connect different networks, the characteristics of each network need to be handled to efficiently connect the networks. These characteristics include network attributes, performance, protocols, signal processing techniques, address indication methods, etc. The intercommunication between networks converts these characteristics to each other, so as to provide required services for users on different networks. [0003] The interworking between such communication networks can be realized by installing an interworking function (IWF) capable of interworking in the communication network or in an indepe...
