Embodiment Construction

[0030] The technical scheme of the present invention aims at the problem that in the prior art in the 3GPP R4 network system, the Iu-PS interface between the SGSN and the RNC adopts the ATM mode to carry out the bearer and may waste too many long-distance transmission resources; and if the existing R4 network Performing upgrade processing, so that the Iu-PS interface between SGSN and RNC is carried based on IP mode, may lead to problems of higher upgrade cost, higher upgrade risk and longer time to complete the upgrade process, so it is proposed that between SGSN and RNC The technical scheme of using the gateway switching device to switch the transmission data on the Iu-PS interface between the RNC and the gateway switching device, even if the Iu-PS interface between the RNC and the gateway switching device is based on ATM mode, and the gateway switching device and the SGSN The Iu-PS interface between them is based on the IP mode of bearer, and the gateway switching device is u...

Abstract

This invention discloses one network conversion device, which comprises the following steps: upper conversion unit to convert the I-PS user surface by ATM form into I-PS user plane in IP form; upper transfer unit to convert upper units into back Cups user plane to SGSN; down conversion unit to convert the I-PS user plane in IP form into I-PS user plane in ATM form; down conversion unit to send theconverted I-PS user plane to RNC.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a gateway switching device, a transmission system for access data and a method thereof. Background technique [0002] The R4 version of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) based on mobile communication technology proposes the use of all-IP transmission in the core network, while the access network (RAN, Radio Access Network) and the access network and core network The bearer links of the Iu interface between all adopt the Asynchronous Transfer Mode (ATM, Asynchronous Transfer Mode) transmission, which leads to the actual networking system of 3GPP R4, because the Iu interface does not implement IP transmission, but uses ATM transmission, making the wireless The Iu-PS interface (Interconnection point between an RNC and a 3G packet-switched CoreNetwork) between the network controller (RNC, Radio Network Controller) and the G...
