Embodiment Construction

[0048] The basic method of the present invention is: the MGC controls the MGW to transfer the user's data service to the MGW with IWF resource equipment for processing, and then directly transparently transmits it to the receiving party or transfers it back to the accessed MGW according to the situation after the processing is completed. When the call establishment stage indicates that it is a data service, it can be directly transparently transmitted, or it can be transmitted back to the connected MGW B; when the call establishment stage is a voice service, and the user switches to the data service during the call, it must Then switch back to the connected MGW). As shown in Figure 2, the solid curve represents the direct transparent transmission service. User B connects to the fixed network FAX equipment through MGW B first. The call of B is transferred to MGW A. On MGW A, after processing by the IWF resource equipment, the data is sent to the mobile gateway switching center ...

Abstract

This invention relates to a method of sharing 1WF resource device. It include following steps: A) The media gate way controller (MGC) controls media gate way (MGW) to access into MGW, which is installed IWF resource device, and treat it. B) After treated by IWF resource device, transmit the data to digital business receive device. This invention can make an IWF resource device be shared by several MGW, to save IWF resource device, and reduce the cost of network.

Description

technical field [0001] The invention relates to network equipment, in particular to a method for sharing IWF (Interworking Function) resource equipment. Background technique [0002] In the 3G wireless network, the circuit domain data services (video services, fax, Internet access, etc.) of mobile phone users are processed on a resource device called IWF. The number is also very small. Usually, an MSC (Mobile Switching Center) will configure IWF resource devices with a certain number of channels, and most of the IWF resource devices are external devices. When the device capacity is too small, the cost of its fixed configuration is relatively high. Figure 1 is a common networking diagram, in which MGC (Media Gateway Controller) and MGW (Media Gateway) form an MSC. Each MGW located in the end office needs to be configured with an IWF resource device. The solid curve is the data flow between the mobile phone and the landline, and the dotted curve is the data flow between the...
