Problems solved by technology

[0005] Since the R4 network requires that the RNC must identify MSC_Server and MGW at the same time, otherwise it cannot be accessed, so the RNC in the original R99 network cannot access the R4 network. For the R99 RNC that can identify both devices at the same time, it is also necessary to modify the data configuration to interrupt the service. It cannot be smoothly connected to the R4 network, and a transmission line needs to be added between RNC and MSC_Server

Embodiment Construction

[0018] Below according to accompanying drawing and embodiment, the present invention is described in further detail:

[0019] As shown in Figure 4, in the present invention, the Radio Network Controller (RNC) combines the Asynchronous Transfer Mode Second Adaptation Layer Bearer Control Protocol (Q.AAL2) message with the Radio Access Network Application Part Call Control Protocol (RANAP) message Both are sent to the media gateway (MGW). The RNC does not know whether the core network is the R99 or R4 network. In this way, the MGW will receive the Q.AAL2 message and the RANAP message at the same time. The Q.AAL2 message is processed by the MGW itself, and the RANAP message is forwarded to Mobile Services Switching Center Server (MSC_Server) processing.

[0020] The MSC_Server can identify both the RNC and the MGW. On the MSC_Server, the MGW is configured as the Signaling Transfer Point (STP) reaching the RNC, so that the RANAP message is first sent to the MGW, and then forwarded...

Abstract

In the invention, radio network controller (RNC) sends message of load control protocol and message of call control protocol to media gateway (MGW). MGW own processes the message of load control protocol, and MGW transmits the received message of call control protocol to a mobile switching center server (MSC) to process. MSC_Server configures MGW as a signaling transit point (STP) to reach RNC. Thus, message of call control protocol is sent to MGW first, and then is transmitted to RNC. The invention provides a method for RNC of R99 to switch in WCDMA R4 network seamless so as to utilize current network equipment fully. The invention makes current network equipment upgrade to R4 network smoothly so as to save investment.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for accessing a radio network controller in a wideband code division multiple access (WCDMA) mobile network. Background technique [0002] In the WCDMA (Wideband Code Division Multiple Access) standard (3G R4) of the third generation mobile communication network version 4, a split gateway structure was introduced, and the mobile service switching center (MSC: Mobile-services Switching Centre) is separated into a media gateway (MGW: Media Gateway) and a mobile service switching center server (MSC_Server). The bearer is terminated at the MGW, and the MSC_Server performs call control, realizing the separation of call control and bearer control. MSC_Server passes the media gateway. The control protocol (H.248) controls the MGW. Both MGW and MSC_Server need signaling point codes to transmit Asynchronous Transfer Mode Second Adaptation Layer Bearer Control Protocol ...
