Embodiment Construction

[0053] Detailed Description of Preferred Embodiments

[0054] Fig. 4 shows the structure of an interworking system providing supplementary services among heterogeneous communication networks according to a preferred embodiment of the present invention.

[0055] As shown in Figure 4, the interworking system for supplementary services between heterogeneous communication networks includes: first and second terminals requesting supplementary services between heterogeneous communication networks; Supplementary services over the first and second communication networks are requested.

[0056] The first communication network includes a third generation (3G) mobile communication network, and the second communication network includes a 2G or 2.5G communication network.

[0057] For example, when the 3G mobile communication network is an ATM-based mobile communication network, and the 2G or 2.5G communication network is a TDM-based communication network for 2G or 2.5G mobile communicati...

Abstract

The invention discloses an interlocking device and method for a supplementary service between different kinds of communication networks. Upon request of the supplementary service based on an opposite network, the interlocking device interconnects the supplementary service apparatus providing the supplementary service based on the opposite network and a line, converts a guide message sent from the supplementary service apparatus into an audio coding system of its own network and transmits the resulting message to a subscriber, converts digit information to control the supplementary service sent from the subscriber receiving the guide message and transmits the converted information in a form of traffic message recognizable by the supplementary service apparatus.Thus providing supplementary service between different kinds of communication networks.

Description

field of invention [0001] The invention relates to intercommunication among heterogeneous communication networks, in particular to a method and system for intercommunication of supplementary services among heterogeneous communication networks. Background technique [0002] FIG. 1 is an example of a mobile communication network structure based on Time Division Multiplexing (TDM) in the prior art. [0003] As shown in Figure 1, a mobile communication network based on TDM includes: a mobile terminal 10, which provides mobile users with 2nd generation or 2.5 generation mobile services; a base station subsystem (BSS) 20, which performs a wireless interface with the mobile terminal 10; Device (BSC) 30 controls base station subsystem 20; Mobile switching center (MSC) 40 processes mobile calls from base station controller 30; Supplementary service device (SSA) 50 communicates with mobile switching center (MSC) by TDM method 40 connections and provide supplementary services.
