Problems solved by technology

[0008] Because the Atrau’ protocol consumes a lot of DSP
This virtually increases the burden on MGW equipment and IWF equipment or modules (increased cost, waste of resources), and reduces the integration of the system
Moreover, the Atrau’ protocol is a link layer synchronization protocol, which needs to cache the data to search the synchronization header of the protocol, which also increases the data delay

Embodiment Construction

[0020] figure 1 As shown, it is a schematic diagram of the networking of the present invention. In the figure, the inter-network communication conversion device 1 (which can be an MGW, a switch or a mobile switch) communicates with the radio network controller 2 through ATM, and forwards the acquired data through the ATM interface Go to the business interworking module (IWF)3. The service interworking module 3 forwards the processed data to the data interface between the inter-network communication conversion device 1 and the fixed communication network 4 (which may be PSTN) through TDM, and sends the data to the fixed communication network 4 through the data interface.

[0021] figure 2 Shown is a schematic diagram of the basic flow of the present invention. In the process of interworking service data transmission processing, the present invention implements the following steps to perform data service interworking.

[0022] Step 101, the inter-network communication switchi...

Abstract

A interworking method of data service between networks includes configuring semi permanent virtual connection information on obtained interworking data from the first communication network by internetwork communication conversion device dynamically, setting up mapping relation of said connection information and channel identification value to call indexing value, sending interworking data being dynamically configured and mapping relation to service interworking module being used to make speed rate treatment on said data then sending treated data to the second communication network by said conversion device.

Description

technical field [0001] The present invention relates to a method for data service intercommunication between networks and an intercommunication conversion system, in particular to a method for circuit domain data service intercommunication between wireless networks and non-wireless networks and an intercommunication conversion system for realizing the method. Background technique [0002] The Interworking Function (IWF for short) is a conversion function during data service interworking, and is a protocol conversion function during circuit domain data service interworking between a wireless network and a non-wireless network. [0003] There is no packet domain defined in GSM, and data services can only be carried out through IWF equipment or modules. If a user wants to surf the Internet through a mobile phone, he can only dial in to the public switched telephone network (PSTN) / Integrated Services Digital Network (ISDN) through a device or module with IWF function. Access th...
