Embodiment Construction

[0037] Embodiments of the present invention provide a method for realizing CS domain services in a flat UMTS network, and the schematic diagram of the applied network is as follows Figure 4 shown. Among them, the eHSPA Node B supports the IuCS interface user plane, and is directly connected to the MGW in the CS domain. Figure 4 In this example, the eHSPA Node B is connected to one MGW as an example, and the number of MGWs that the eHSPA Node B can connect to is not limited in actual networking.

[0038] For this direct connection mode, the eHSPA Node B needs to support the IuCS interface protocol stack on the IuCS interface. The content of the IuCS interface protocol stack is as follows Figure 5 As shown, the functions that eHSPA Node B needs to support are detailed in Figure 5 The middle gray area further includes the Transport Network Layer and the Radio Network Layer.

[0039]For the transport network layer: if the transport network layer uses IP transmission mode, ...

Abstract

The embodiment of the invention discloses a method for realizing circuit switching (CS) domain service in a flat and universal mobile telecommunication system (UMTS), a system and equipment. In the UMTS, a base station is connected with a CS domain user surface by an IuCS interface. The method comprises the following steps of: establishing transmission network layer connection with the CS domain user surface by the IuCS interface; and establishing wireless network layer connection with the CS domain user surface on the basis of the transmission network layer connection; and carrying out establishment of CS domain services on the basis of the wireless network layer. By using the embodiment of the invention, in the flattened UMTS network, the eHSPA (evolved high speed packet access) Node B of a core network of the CS domain user surface can be directly connected, so that the connection between the eHSPA Node B and the user surface of an MGW (Media Gateway) or an MSC (Mobile Switching Center) in the CS domain does not need extra transmission network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and equipment for realizing CS (Circuit Switching, circuit switching) domain services in a flat UMTS (Universal Mobile Telecommunications System, universal mobile communication system). Background technique [0002] The flattening of the network structure can reduce the level of network nodes, which is the current development trend of mobile networks. For example, WiMax (Worldwide Interoperability for Microwave Access, LTE (Long Term Evolution, long-term evolution), etc. all adopt a flat network structure, and the UMTS network with a non-flat network structure is gradually becoming flat. evolve. Traditional UMTS network structure such as figure 1 As shown, the core network part includes MSC (Mobile Switching Center, mobile switching center), SGSN (Serving GPRS Supporting Node, GPRS service support node), GGSN (Gateway GPRS Supporting Node, GPRS g...
